Irreducible dorsal metatarsophalangeal joint dislocation of the fifth toe: a case report.

The authors report a case of a dorsal dislocation of the fifth metatarsophalangeal joint that could not be reduced by closed manipulation, and instead required open reduction with Kirschner-wire fixation to maintain alignment. Although metatarsophalangeal joint dislocation is not unheard of, it is not common for the deformity to resist efforts at closed reduction and immobilization or percutaneous pin fixation. One year after surgery, the patient described in this article had returned to his baseline activity level, and was ambulating without pain while demonstrating full range of motion in the fifth metatarsophalangeal joint.

Lymphangiomyoma of the shoulder: an exceptional localisation. A case report.

Lymphangioleiomyomatosis (LAM) is a rare condition usually occurring in young women of childbearing age. It is characterised by the presence of abnormal smooth muscle cells (LAM cells) in the lungs, lymph nodes, and/or other organs, with a few reports of isolated extrapulmonary cases. We report the case of a 26-yr-old female who presented with a painless shoulder mass. Ultrasonography, computed tomography and magnetic resonance imaging revealed an intermuscular mass with cystic and solid tissue components, measuring 6 cm x 4 cm. The mass was removed surgically after the diagnosis of LAM was made following tru-cut biopsy. This case corresponds to an exceptional localisation of LAM.

Bizarre parosteal osteochondromatous proliferation (Nora's lesion) of the forefoot.

Nora's tumour is an uncommon benign tumour, involving mostly tubular bones of hands and feet, and characterized by a proliferation of chondroid, bony and fibrous tissues. Main differential diagnoses are osteochondroma, chondrosarcoma, and osteosarcoma. The authors report a case involving the left foot. The diagnosis was suspected by imaging characteristic features and was confirmed by histological examination. Treatment was surgical, with complete excision. There are no clinical or radiological signs of recurrence on further review one year postoperatively.

Isolated complex dislocation of the metacarpophalangeal joint of the third finger.

Two unusual cases of isolated closed complex dislocation of the metacarpophalangeal joint of the third finger are presented. The single most important element preventing reduction was interposition of the volar plate between the proximal end of the phalanx and the head of the metacarpal, but the deep transverse ligament was also intimately involved in the entrapment mechanism. Such dislocations require open reduction as in the two cases presented, and we found the dorsal approach to be simple and effective.
