![]() ![]() Diagnosis is may clinically with worsening posterior shoulder pain during maximal abduction and external rotation (position of late cocking) associated with. Both oblique fractures and transverse fractures with >30° of angulation usually require closed reduction and Kirschner wire fixation ( CRIF) 2,3. Internal impingement is a cause of shoulder pain in overhead athletes caused by repetitive impingement between the undersurface of the rotator cuff and the posterosuperior glenoid. The vast majority of epibasal fractures are considered stable and can be treated conservatively with thumb spica immobilization for 4-6 weeks 2,3. bone healing may occur as a combination of the above two process depending on the stability throughout the construct. occurs with non-rigid fixation, as fracture braces, external fixation, bridge plating, intramedullary nailing, etc. ![]() Plain radiographĮpibasal fractures are divided according to the direction of fracture into transverse and oblique and can be variably angulated and displaced. involves responses in the periosteum and external soft tissues. CT scan is helpful for intra-articular assessment and operative planning. Diagnosis is made with plain radiographs of the humerus and elbow. The causative mechanism is axial overload along the first metacarpal with simultaneous flexion. Distal Humerus Fractures are traumatic injuries to the elbow that comprise of supracondylar fractures, single column fractures, column fractures or coronal shear fractures. Plain films are usually sufficient to diagnose and assess epibasal fractures however, if adequate views cannot be obtained or there is suspicion of intra-articular involvement, further assessment with CT is prudent 3. Bennett’s injury is a fracture subluxation of the first carpo-metacarpal joint. The metacarpal fractures constitute 18e44 of hand fractures. Preface is an educational resource for orthopaedic surgeons designed to improve training through the communal efforts of those who use it as a. These fractures usually result from longitudinal axial loading 5. The incidence of metacarpal fractures is 8.4 per 10,000 per-son-years.1These may present as isolated fracture, multiple meta-carpal fractures or in combination with bony injuries to other extremity. 'Because the fracture-dislocation of the base of the fifth metacarpal is pathologically and radiographically similar to the Bennett fracture of the thumb metacarpal, it is referred to as a ' reversed Bennett ', ' ulnar Bennett ', or ' Tenneb ' (Bennett spelled backwards) fracture'. ![]() Epibasal fracture of the thumb accounts for approximately 3% of all hand fractures and 16% of metacarpal fractures and is mostly (>80%) seen in young men 4. ![]()
