It is more common in developing countries. A positive metacarpal sign means that a tangential line drawn from the distal end of head of fourth and fifth metacarpals passed through the distal end of third metacarpal (Figs 1A and B), while.. 1) Pseudohypoparathyroidism, 2) Hyperparathyroidism, 3) Hyperthyroidism, 4) Hypothyroidism, 5) NULL. Named accessory bones include: Fractures to metacarpal bones account for 30-40% of all hand fractures, of which 25% occur in the first metacarpal (second to fractures to the fifth metacarpal bone). Treatment and prognosis. The vast majority of Colles fractures can be treated with closed reduction and cast immobilization. Typically, Monteggia fracture-dislocations occur as the result of a fall onto an outstretched hand (FOOSH) 4.. The clavicle is the only long bone in the body that lies horizontally.Together with the shoulder blade, it makes up the shoulder girdle. The first metacarpal bone is short and thick with a shaft thicker and broader than those of the other metacarpal bones. Besides the metacarpophalangeal joints, the metacarpal bones articulate by carpometacarpal joints as follows: Carpometacarpal joints of the left hand. A member of the NBA 75th Anniversary Team, he is a nine-time NBA All-Star and earned the NBA Most Valuable Player Award (MVP) for the 201617 season.He is also a nine-time All-NBA Team member, led the Dubuque: McGraw-Hill, 2010. Odontoid process fracture, also known as a peg or dens fracture, occurs where there is a fracture through the odontoid process of C2. 562 Fracture, sprain, strain and dislocation except femur, hip, pelvis and thigh with mcc; 563 Fracture, sprain, strain and dislocation except femur, hip, The cast extends from below the elbow to the metacarpal heads and holds the wrist somewhat flexed and in ulnar deviation 4 - for those of you familiar with Australian rules football; this position is reminiscent of the position adopted when intra-articular body fracture; The calcaneus is also a common site of stress fractures, occurring in the posterosuperior aspect. Russell Westbrook III (born November 12, 1988) is an American professional basketball player for the Los Angeles Lakers of the National Basketball Association (NBA). Therefore the radius is considered to be the larger of the two. [citation needed], These centres unite before fifteenth year in girls and seventeenth year in boys. A fracture of the fourth and/or fifth metacarpal bones transverse neck secondary due to axial loading is known as a boxer's fracture. The base of each metatarsal bone articulates with one or more of the tarsal bones at the tarsometatarsal joints, and the head with one of the first row of phalanges at the metatarsophalangeal joints.Their bases also articulate with each other at the intermetatarsal joints. Non-operative management 6 may be indicated in the setting of minimally displaced fracture. The narrowed part in the middle is referred to as the body (or shaft) of the bone. The dorsal surface of the body is divided by an oblique ridge, There are two classification systems 5,6. Pathology Anatomy. Closed fracture of base of right fifth metacarpal; Right fifth metacarpal base (hand bone) fracture; ICD-10-CM S62.316A is grouped within Diagnostic Related Group(s) (MS-DRG v 40.0):. The first metacarpal bone is short and thick with a shaft thicker and broader than those of the other metacarpal bones. History and etymology An elongated lateral tubercle of the posterior process of the talus is referred to as a Stieda process, so occasionally these fractures are described as Stieda process fractures.. A Cedell fracture is a fracture of the medial tubercle of the posterior process. If immobilization is impractical (large body habitus) or the patient has polytrauma, surgical management may also be indicated. - Malrotation metacarpal fracture - Malrotation due to metacarpal fracture Interosseus muscles and lumbricals insert onto the base of the proximal phalanx and flex the proximal fragment. Management depends not only on the type of fracture but also importantly on the functional status and living situation of the patient. It presents on its base one facet on its superior surface, which is concavo-convex and articulates with the hamate, and one on its radial side, which articulates with the fourth metacarpal.. On its ulnar side is a prominent tubercle for the insertion of the tendon of the extensor carpi ulnaris muscle.. Deep dissection. The volar surface is grooved in the middle line for the passage of the flexor tendons, and marked on either side by an articular eminence continuous with the terminal articular surface.[2]. The peripheral metacarpals (those of the thumb and little finger) form the sides of the cup of the palmar gutter and as they are brought together they deepen this concavity. This article incorporates text in the public domain from page 227 ofthe 20th edition of Gray's Anatomy (1918). The thumb has several associated accessory bones. The Lisfranc joint articulates the tarsus with the metatarsal bases, whereby the first three metatarsals articulate respectively with the three cuneiforms, and the 4 th and 5 th metatarsals with the cuboid.. Palmar view of the left hand (fourth metacarpal shown in yellow). This article incorporates text in the public domain from page 228 ofthe 20th edition of Gray's Anatomy (1918). 562 Fracture, sprain, strain and dislocation except femur, hip, pelvis and thigh with mcc; 563 Fracture, sprain, strain and dislocation except femur, hip, location (distal pole, waist, proximal pole) involvement of articular surfaces; displacement or step; humpback deformity due to angulation between proximal and distal parts; alignment. The narrowed part in the middle is referred to as the body (or shaft) of the bone. The Greek physician Galen used to refer to the metacarpus as . The five metacarpal bones, numbered. Classification. Classification. Insufficiency fractures are a type of stress fracture, which are the result of normal stresses on abnormal bone. As with the four other metatarsal bones it can be divided into three parts; a base, body and head. Inoue H, et al. Conveniently the Salter-Harris types can be remembered by the mnemonic SALTR.. type I. slipped; 5-7%; fracture plane passes all the way through the location (distal pole, waist, proximal pole) involvement of articular surfaces; displacement or step; humpback deformity due to angulation between proximal and distal parts; alignment. Types of metacarpal fracture. The clavicle is the only long bone in the body that lies horizontally.Together with the shoulder blade, it makes up the shoulder girdle. Typically, Monteggia fracture-dislocations occur as the result of a fall onto an outstretched hand (FOOSH) 4.. Pathology Anatomy. Right hand. If immobilization is impractical (large body habitus) or the patient has polytrauma, surgical management may also be indicated. Soft tissue swelling, denoted by the arrow, is perhaps a more obvious finding than the fracture itself. First metacarpal of the left hand (shown in red). scapholunate interval Several types of treatment exist ranging from non-operative techniques, with or without immobilization, to operative techniques using closed or open reduction and internal fixation (ORIF). Classification. The base of each metatarsal bone articulates with one or more of the tarsal bones at the tarsometatarsal joints, and the head with one of the first row of phalanges at the metatarsophalangeal joints.Their bases also articulate with each other at the intermetatarsal joints. The Frykman classification of distal radial fractures is based on the AP appearance and encompasses the eponymous entities of Colles fracture, Smith fracture, Barton fracture, chauffeur fracture.. delayed presentation (> 3 weeks) high operative risk; fracture characteristics. Surfaces. Close up. The dorsal surface of the body is divided by an oblique ridge, The dorsal surface of the body is divided by an oblique ridge, Animation. The neck of a metacarpal is a common location for a boxer's fracture, but all parts of the metacarpal bone (including head, body and base) are susceptible to fracture. First metacarpal bone of the left hand. The Frykman classification of distal radial fractures is based on the AP appearance and encompasses the eponymous entities of Colles fracture, Smith fracture, Barton fracture, chauffeur fracture.. Classification. Insufficiency fractures are a type of stress fracture, which are the result of normal stresses on abnormal bone. There are two clavicles, one on the left and one on the right. Patients with any neurological deficit or unstable fracture patterns (damage to the posterior ligaments) will need surgical fixation to decompress the spinal cord and stabilize the fracture 5. The clavicle, or collarbone, is a slender, S-shaped long bone approximately 6 inches (15 cm) long that serves as a strut between the shoulder blade and the sternum (breastbone). The metacarpals, particularly the base of the first metacarpal are usually fractured as a result of impact or sudden trauma such as punching, or a fall onto the hand if your thumb is extended out to the side. Saladin, Kenneth S. "Capt. Anderson and D'Alonzo The middle metacarpals are tightly united to the carpus by intrinsic interlocking bone elements at their bases. The vast majority of Colles fractures can be treated with closed reduction and cast immobilization. Epidemiology. A member of the NBA 75th Anniversary Team, he is a nine-time NBA All-Star and earned the NBA Most Valuable Player Award (MVP) for the 201617 season.He is also a nine-time All-NBA Team member, led the Classification. Treatment and prognosis. Metacarpus (yellow). Posterior (dorsal) view. Although traditionally the mandible and base of skull are thought to form a complete bony ring, interrupted only by the TMJs.This should mean that the mandible should fracture in two places (akin to the bony pelvis) making single fractures uncommon, but this in fact not the case, with ~40% of History and etymology That bone is known as a metacarpal. Insufficiency fractures are a type of stress fracture, which are the result of normal stresses on abnormal bone. Surfaces. Odontoid process fracture, also known as a peg or dens fracture, occurs where there is a fracture through the odontoid process of C2. Terminology. The first metacarpal bone is short and thick with a shaft thicker and broader than those of the other metacarpal bones. An open fracture is where bone has pierced though the skin. The head (caput) or digital extremity presents an oblong surface markedly convex from before backward, less so transversely, and flattened from side to side; it articulates with the proximal phalanx.

Usually, this kind of fracture occurs as the result of a fall on an outstretched arm and is often associated with a distal radius fracture. Classification, management and long-term results. 5th, Green DP, Pederson WC, Hotchkiss RN, Wolfe SW (Eds), Elsevier - Churchill Livingstone, Philadelphia 2005. p.277. They should not be confused with fatigue fractures which are due to abnormal stresses on normal bone, or with pathological fractures, the result of diseased, weakened bone due to focal pathology [5]. Anterior (palmar) view. A Shepherd fracture refers to a fracture of the lateral tubercle of the posterior process. This contrasts to the other four metacarpal bones where the secondary centre is found in the head. The Lisfranc ligament attaches the medial cuneiform to the 2 nd metatarsal base via three bands, the dorsal ligament, interosseous The mechanism of injury is variable, and can occur both during flexion or extension, and with or without compression 5. Another method of classification is as type A fractures: the anterior process of the calcaneus is fractured; type B: fracture of the mid calcaneus, trochlear process, and sustentaculum tali Classification. Usually, this kind of fracture occurs as the result of a fall on an outstretched arm and is often associated with a distal radius fracture. ; The opisthenar area (dorsal) is the corresponding area on the posterior part of the hand. The fourth metacarpal bone (metacarpal bone of the ring finger) is shorter and smaller than the third.. The Lisfranc joint articulates the tarsus with the metatarsal bases, whereby the first three metatarsals articulate respectively with the three cuneiforms, and the 4 th and 5 th metatarsals with the cuboid.. The narrowed part in the middle is referred to as the body (or shaft) of the bone. Although traditionally the mandible and base of skull are thought to form a complete bony ring, interrupted only by the TMJs.This should mean that the mandible should fracture in two places (akin to the bony pelvis) making single fractures uncommon, but this in fact not the case, with ~40% of There are two classification systems 5,6. Anatomy & Physiology: the Unity of Form and Function. In four-legged animals, the metacarpals form part of the forefeet, and are frequently reduced in number, appropriate to the number of toes. A shortened fourth metacarpal bone can be a symptom of Kallmann syndrome, a genetic condition which results in the failure to commence or the non-completion of puberty. The Salter-Harris classification was proposed by Salter and Harris in 1963 1 and at the time of writing (June 2016) remains the most widely used system for describing physeal fractures.. Approximate Synonyms. Types of metacarpal fracture. Patients with any neurological deficit or unstable fracture patterns (damage to the posterior ligaments) will need surgical fixation to decompress the spinal cord and stabilize the fracture 5. On the palmar aspect of the articular surface there is a pair of eminences or tubercles which articulate with the radial and ulnar sesamoid bones of the thumb metacarpophalangeal joint; the lateral eminence is larger than the medial. Non-operative management 6 may be indicated in the setting of minimally displaced fracture. Traditionally this avulsion fracture has been ascribed to the insertion of peroneus brevis and is caused by forcible inversion of the foot in plantar flexion, as may occur while stepping on a curb or climbing steps. It assesses the pattern of fractures, involvement of the radioulnar joint and presence of a distal ulnar fracture.. The fifth metatarsal is analogous to the fifth metacarpal bone in the hand. The mechanism of injury is variable, and can occur both during flexion or extension, and with or without compression 5. - Malrotation metacarpal fracture - Malrotation due to metacarpal fracture 5th, Green DP, Pederson WC, Hotchkiss RN, Wolfe SW (Eds), Elsevier - Churchill Livingstone, Philadelphia 2005. p.277. The origin of the first dorsal interosseous muscle is on the ulnar aspect of the base, and can sometimes extend onto the shaft. Insertions are shown in red. Epidemiology. The metacarpals form a transverse arch to which the rigid row of distal carpal bones are fixed. Terminology. Triepel, H. (1908). The Bado classification is used to subdivide the fracture-dislocation into four types which all have different treatment options and prognoses and is based on the principle that the direction in which the apex of the ulnar fracture points is the same The first metatarsal articulates with the medial cuneiform, and to a small extent to the Management depends not only on the type of fracture but also importantly on the functional status and living situation of the patient. As with the four other metatarsal bones it can be divided into three parts; a base, body and head. The body (shaft) is prismoid in form, and curved, so as to be convex in the longitudinal direction behind, concave in front. There are two clavicles, one on the left and one on the right. Closed fracture of base of right fifth metacarpal; Right fifth metacarpal base (hand bone) fracture; ICD-10-CM S62.316A is grouped within Diagnostic Related Group(s) (MS-DRG v 40.0):. Mandibular fractures are relatively common especially among young men. Management depends not only on the type of fracture but also importantly on the functional status and living situation of the patient. location (distal pole, waist, proximal pole) involvement of articular surfaces; displacement or step; humpback deformity due to angulation between proximal and distal parts; alignment. A Shepherd fracture refers to a fracture of the lateral tubercle of the posterior process. Treatment and prognosis. Looser zones are also a type of insufficiency fracture. Therefore the radius is considered to be the larger of the two. Although traditionally the mandible and base of skull are thought to form a complete bony ring, interrupted only by the TMJs.This should mean that the mandible should fracture in two places (akin to the bony pelvis) making single fractures uncommon, but this in fact not the case, with ~40% of Figure 2: Fracture of the base of the 5th metacarpal. Close up. Widgerow AD, Ladas CS. It assesses the pattern of fractures, involvement of the radioulnar joint and presence of a distal ulnar fracture.. A boxers fracture is when you break a bone at the base of your finger, near the knuckle or neck of the bone. delayed presentation (> 3 weeks) high operative risk; fracture characteristics. To the right, a close-up view of the base of the metacarpal shows the fracture line, outlined in red in the image below. That bone is known as a metacarpal. The ring metacarpal is somewhat more mobile while the fifth metacarpal is semi-independent.[1]. Print. Its narrow shaft connects its widened base and rounded head; the former consisting of a thick cortical bone surrounding the open medullary canal; the latter two consisting of cancellous bone surrounded by a thin cortical shell. Treatment and prognosis. Memorial on the anatomical nomenclature of the anatomical society. The first metacarpal bone or the metacarpal bone of the thumb is the first bone proximal to the thumb. Russell Westbrook III (born November 12, 1988) is an American professional basketball player for the Los Angeles Lakers of the National Basketball Association (NBA). Metacarpals shown in red. For example, someone who lives alone may not be able to do so without the use of one arm. An elongated lateral tubercle of the posterior process of the talus is referred to as a Stieda process, so occasionally these fractures are described as Stieda process fractures.. A Cedell fracture is a fracture of the medial tubercle of the posterior process. Pathology. The neck of a metacarpal is a common location for a boxer's fracture, but all parts of the metacarpal bone (including head, body and base) are susceptible to fracture. Deep dissection. To the right, a close-up view of the base of the metacarpal shows the fracture line, outlined in red in the image below. It presents on its base one facet on its superior surface, which is concavo-convex and articulates with the hamate, and one on its radial side, which articulates with the fourth metacarpal.. On its ulnar side is a prominent tubercle for the insertion of the tendon of the extensor carpi ulnaris muscle.. Galeazzi fracture-dislocations are unstable requiring surgical intervention, which involves open reduction and internal fixation (ORIF) of the radial fracture, intraoperative assessment of the distal radioulnar joint for reducibility and stability, and subsequent Kirschner wire fixation of the ulna to the radius, triangular fibrocartilage complex When present, these bones are usually found near the base and trapezium and are the products of an additional centre of ossification, usually of the trapezium, that failed to fuse with the associated bone. intra-articular body fracture; The calcaneus is also a common site of stress fractures, occurring in the posterosuperior aspect. Looser zones are also a type of insufficiency fracture. In addition to stating that a fracture is present, a number of features should be sought and commented upon: fracture. Mechanism. type I: avulsion of anterior glenoid margin; type II: transverse or oblique fracture through glenoid fossa exiting inferiorly; type III: oblique fracture through glenoid fossa exiting superiorly and associated with acromioclavicular joint injury; type IV: transverse fracture exiting through the medial scapular border Soft tissue swelling, denoted by the arrow, is perhaps a more obvious finding than the fracture itself. There are two clavicles, one on the left and one on the right. Blunted metacarpals (particularly the fourth metacarpal) are a symptom of nevoid basal-cell carcinoma syndrome. Mandibular fractures are relatively common especially among young men. The clavicle is the only long bone in the body that lies horizontally.Together with the shoulder blade, it makes up the shoulder girdle. Its narrow shaft connects its widened base and rounded head; the former consisting of a thick cortical bone surrounding the open medullary canal; the latter two consisting of cancellous bone surrounded by a thin cortical shell. [10][11] Meta is Greek for beyond and carpal from Ancient Greek (karps, wrist). [1]. The first metatarsal articulates with the medial cuneiform, and to a small extent to the Animation. Although it appears complicated, These type of fractures are more common in children, especially aged 5-10 years, due to the elasticity of their bones. Widgerow AD, Ladas CS. Another method of classification is as type A fractures: the anterior process of the calcaneus is fractured; type B: fracture of the mid calcaneus, trochlear process, and sustentaculum tali Indications for non-operative management include: patient factors. [4] Intraarticular fracture-dislocations of the metacarpal head or base may require surgical fixation, as fragment displacement affecting the joint surface is rarely tolerated well.[4]. It presents three surfaces: medial, lateral, and dorsal. In digitigrade and unguligrade animals, the metacarpals are greatly extended and strengthened, forming an additional segment to the limb, a feature that typically enhances the animal's speed. - Malrotation metacarpal fracture - Malrotation due to metacarpal fracture 5th, Green DP, Pederson WC, Hotchkiss RN, Wolfe SW (Eds), Elsevier - Churchill Livingstone, Philadelphia 2005. p.277. type I: avulsion of anterior glenoid margin; type II: transverse or oblique fracture through glenoid fossa exiting inferiorly; type III: oblique fracture through glenoid fossa exiting superiorly and associated with acromioclavicular joint injury; type IV: transverse fracture exiting through the medial scapular border Mechanism. It is for this reason that the 5 th metatarsal base must be included in the lateral ankle projection of an ankle series, especially when performed for an There are two classification systems 5,6. The ulna is usually slightly longer than the radius, but the radius is thicker. On either side of the head is a tubercle for the attachment of the collateral ligament of the metacarpophalangeal joint. Closed fracture of base of right fifth metacarpal; Right fifth metacarpal base (hand bone) fracture; ICD-10-CM S62.316A is grouped within Diagnostic Related Group(s) (MS-DRG v 40.0):. There are three main types of metacarpal fracture: Conveniently the Salter-Harris types can be remembered by the mnemonic SALTR.. type I. slipped; 5-7%; fracture plane passes all the way through the Dorsal view of the left hand (first metacarpal shown in yellow). If immobilization is impractical (large body habitus) or the patient has polytrauma, surgical management may also be indicated. It assesses the pattern of fractures, involvement of the radioulnar joint and presence of a distal ulnar fracture.. Rarely, a torus fracture may refer to the fracture of an oral torus, and there is potential for the two terms to be confused 10. Anderson and D'Alonzo Characteristics. On the palmar and lateral side of the base is the insertion of the tendon of the abductor pollicis longus muscle, usually featuring a small tubercle. Fractures of the base of the middle phalanx of the finger. Classification. International Anatomical Nomenclature Committee (1966). Galeazzi fracture-dislocations are unstable requiring surgical intervention, which involves open reduction and internal fixation (ORIF) of the radial fracture, intraoperative assessment of the distal radioulnar joint for reducibility and stability, and subsequent Kirschner wire fixation of the ulna to the radius, triangular fibrocartilage complex intra-articular body fracture; The calcaneus is also a common site of stress fractures, occurring in the posterosuperior aspect. Galeazzi fracture-dislocations are unstable requiring surgical intervention, which involves open reduction and internal fixation (ORIF) of the radial fracture, intraoperative assessment of the distal radioulnar joint for reducibility and stability, and subsequent Kirschner wire fixation of the ulna to the radius, triangular fibrocartilage complex Classification. The cast extends from below the elbow to the metacarpal heads and holds the wrist somewhat flexed and in ulnar deviation 4 - for those of you familiar with Australian rules football; this position is reminiscent of the position adopted when A positive metacarpal sign means that a tangential line drawn from the distal end of head of fourth and fifth metacarpals passed through the distal end of third metacarpal (Figs 1A and B), while.. 1) Pseudohypoparathyroidism, 2) Hyperparathyroidism, 3) Hyperthyroidism, 4) Hypothyroidism, 5) NULL. scapular fracture; clavicle fracture; distal radial fracture (especially Colles fracture) Treatment and prognosis. The fracture complex results from a direct blow to the malar eminence and results in three distinct fracture components that disrupt the anchoring of the zygoma. 80% of fractures to the first metacarpal occur at its base. The Salter-Harris classification was proposed by Salter and Harris in 1963 1 and at the time of writing (June 2016) remains the most widely used system for describing physeal fractures.. [5] When the both sexes were considered together, the ossification of base of first metacarpal was seen to start between 13 and 41 months. Mandibular fractures are relatively common especially among young men. 5th, Green DP, Pederson WC, Hotchkiss RN, Wolfe SW (Eds), Elsevier - Churchill Livingstone, Philadelphia 2005. p.277. The configuration of the thumb carpometacarpal joint plays an important role in the mechanism of opposition. The index metacarpal is the most firmly fixed, while the thumb metacarpal articulates with the trapezium and acts independently from the others. Conveniently the Salter-Harris types can be remembered by the mnemonic SALTR.. type I. slipped; 5-7%; fracture plane passes all the way through the An open fracture is where bone has pierced though the skin. Characteristics. The fifth metatarsal is analogous to the fifth metacarpal bone in the hand. The base (basis) or carpal extremity is of a cuboidal form, and broader behind than in front: it articulates with the carpal bones and with the adjoining metacarpal bones; its dorsal and volar surfaces are rough, for the attachment of ligaments.[2]. Metacarpals There are five metacarpals, each one related to a For example, someone who lives alone may not be able to do so without the use of one arm. The base is the part closest to the ankle and the head is closest to the toes. The cast extends from below the elbow to the metacarpal heads and holds the wrist somewhat flexed and in ulnar deviation 4 - for those of you familiar with Australian rules football; this position is reminiscent of the position adopted when To the right, a close-up view of the base of the metacarpal shows the fracture line, outlined in red in the image below. A boxers fracture is when you break a bone at the base of your finger, near the knuckle or neck of the bone. Palmar view. There are three main types of metacarpal fracture: type I: avulsion of anterior glenoid margin; type II: transverse or oblique fracture through glenoid fossa exiting inferiorly; type III: oblique fracture through glenoid fossa exiting superiorly and associated with acromioclavicular joint injury; type IV: transverse fracture exiting through the medial scapular border - Malrotation metacarpal fracture - Malrotation due to metacarpal fracture Interosseus muscles and lumbricals insert onto the base of the proximal phalanx and flex the proximal fragment. The Lisfranc ligament attaches the medial cuneiform to the 2 nd metatarsal base via three bands, the dorsal ligament, interosseous They should not be confused with fatigue fractures which are due to abnormal stresses on normal bone, or with pathological fractures, the result of diseased, weakened bone due to focal pathology The Salter-Harris classification was proposed by Salter and Harris in 1963 1 and at the time of writing (June 2016) remains the most widely used system for describing physeal fractures.. The fourth metacarpal bone (metacarpal bone of the ring finger) is shorter and smaller than the third.. 361-64. Non-operative management 6 may be indicated in the setting of minimally displaced fracture. It is a common site of fracture- 70% of all carpal fractures, often injured by a fall onto an outstretched limb; Pisiform, hamate and base 5th metacarpal Ulnar nerve (C7,8) Radiocarpal Jt Supination (of forearm) Supinator 60 Lateral epicondyle of humerus and ridge near radial notch of The dorsal surface, broad and flat, supports the tendons of the extensor muscles. That bone is known as a metacarpal. Metacarpals There are five metacarpals, each one related to a Fractures of the base of the middle phalanx of the finger. The first metacarpal bone is short and thick with a shaft thicker and broader than those of the other metacarpal bones. Shultz, S. J., Houglum, P. A., Perrin, D. H. (2010).
