A boxer's fracture is the break of the fifth metacarpal bone of the hand near the knuckle. [4] Occasionally, it is used to refer to fractures of the fourth metacarpal as well. [1] Symptoms include pain and a depressed knuckle. [2] Classically, it occurs after a person hits an object with a closed fist. [3]
A short fourth metacarpal bone can also be found in Turner syndrome, a disorder involving sex chromosomes. A fracture of the fourth and/or fifth metacarpal bones transverse neck secondary due to axial loading is known as a boxer's fracture. [1]
intra articular comminuted fracture of base of first metacarpal: axial load along the metacarpal causing splitting of the proximal articular surface: Rolando's fracture at Wheeless' Textbook of Orthopaedics online Runner's fracture: Running: stress fracture of distal fibula 3–8 cm above the lateral malleolus: repeated axial stress on fibula
Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture. Generally, bone fracture treatment consists of a doctor reducing (pushing) displaced bones back into place via relocation with or without anaesthetic, stabilizing their position to aid union, and then waiting ...
Arthroplasty surgery for TMC OA removes part or all of the trapezium. [27] Surgery may also support the metacarpal by reconstructing a ligament using a tendon graft or weave. Surgery may also place something in the space where the trapeziometacarpal joint was, either a tendon wrapped up into a ball or a prosthesis.
Rolando fracture – a comminuted intra-articular fracture through the base of the first metacarpal bone; Bennett's fracture – a fracture of the base of the first metacarpal bone which extends into the carpometacarpal (CMC) joint [15] Boxer's fracture – a fracture at the neck of a metacarpal; Broken finger – a fracture of the carpal ...
Due to the relation between their insertions on the sides of the metacarpal head and the axis of rotation in the joint, the collateral ligaments are taut in flexion but lax in extension, while the accessory collateral ligaments are lax in flexion but taut in extension. [1]
A fracture of the fourth and/or fifth metacarpal bones transverse neck secondary due to axial loading is known as a boxer's fracture. [1] [[[Boxer%27s_fracture#{{{section}}}| contradictory]]] The fifth metacarpal bone is the most common bone to be injured when throwing a punch.
