    ABSTRACT: A case of volar and ulnar solitary dislocation of the scaphoid of the right hand associated with type 3 Monteggia fracture dislocation (Bado) of the same limb is reported. It was complicated by median nerve palsy which was masked by the compartment syndrome of the forearm. He was treated with open reduction, internal fixation and decompression of the median nerve. The functional result is good. Solitary dislocation of the scaphoid is a very rare carpal bone injury. Isolated case reports were published in the past. However, it was complicated with median nerve palsy and masked by the compartment syndrome of the forearm that had never been described.

    ABSTRACT: A subcapital femoral neck fracture complicating a healed trochanteric fracture is rare. Such cases are managed in a rather heterogeneous manner, i.e. there exists a mixture of cases treated by either fixed angle devices or dynamic compression screws. We describe 5 patients who developed subcapital femoral neck fractures after healed trochanteric fractures treated with dynamic compression screws. The subjects' clinical data, operative records, and radiographs have been studied retrospectively and the literature reviewed. The risk factors for such a complication include being of advanced age, female, osteoporotic, and having a small femoral head and neck, and a basicervical type of fracture.

    ABSTRACT: An easy pedicle vascular bone graft technique for the management of nonunion of humeral shaft fracture is described. The distal and lateral part of the humerus, including the lateral epicondyle, is transferred to the nonunion site of the humerus. This vascular bone graft is based on the accessory radial collateral artery. It promotes healing of the nonunion.

    ABSTRACT: A new mechanism of injury of the forearm bones, crisscross injury, is described. It is more common than the Essex-Lopresti fracture dislocation. The old concept of isolated injury of one side of the radioulnar joint may be challenged. It often occurs in Mason type II fracture dislocation of the radial head or dislocation of radioulnar joints. The first part was a cadaveric study of the crisscross injury of forearms. The second part was a clinical study of the crisscross injury in some cases of Mason type II fracture radial head and double dislocation of the radioulnar joint. The cadaveric study confirmed a stable crisscross fracture dislocation injury with intact interosseous membrane. The clinical study echoed the presence of this injury by imaging techniques. The crisscross injury mechanism explains the mirror pathogenesis of the traumatic fracture dislocation of the distal and proximal radioulnar joints with intact shaft of the radius and ulna. Co-existing subluxation or dislocation of the other radioulnar articulation must not be overlooked in cases of fracture dislocation of one radioulnar joint. Two types of crisscross injury of forearm bones are proposed.

    ABSTRACT: Tuberculous osteomyelitis is an uncommon disease entity. We report two cases of tuberculous infection of the scapula, one involving the acromion and one involving the body of the scapula. Tuberculosis is still an important differential diagnosis in unusual or chronic bone conditions.

    ABSTRACT: Solitary dislocation of the scaphoid can be classified as simple, or complex if the distal carpal row is included. It may be total or partial. Partial dislocation of the proximal pole may occur in a radial, palmar or dorsal direction. Each type has a different significance in terms of surgical approaches, complications and prognosis.
