A case of an anterior interosseous nerve palsy associated with a Monteggia fracture-dislocation is presented. The fracture of the ulna was reduced and stabilized with a plate, and the proximal radioulnar dislocation was also reduced. The nerve recovery was spontaneous and complete. A satisfactory result was obtained, without pain or functional sequelae.
A case of bilateral intraosseous lipomas of the calcaneus is presented. The bilateral localization of calcaneal intraosseous lipomas is extremely rare.
A case of trigger finger due to a lipoma of the tendon sheath at the wrist is presented. Lipoma of the tendon sheath is a very rare tumor. In the case reported, the symptoms disappeared after surgical treatment.
We present two patients with avulsion-fractures involving the superior scapular edge. One of the fractures was bilateral. The treatment for both patients was conservative and gave excellent functional results. The different mechanisms that produced the lesions are discussed. It is our opinion that the mechanism was indirect in each case.
We present case of bipolar dislocation of the right clavicle in a 26 year-old man. He was treated by open reduction plus internal fixation with Kirschner wires at the acromioclavicular joint, and orthopedic reduction of the sternoclavicular joint plus percutaneous osteosynthesis with Kirschner wires. An excellent (functional and cosmetic) result was obtained. A review of the literature is included, and some aspects of the treatment are discussed.
The authors present a case of intramuscular leiomyoma of the lower limb. Its location was the internal gastrocnemius muscle of the right leg. The treatment consisted in ablation of the tumor, which was well delimited and had well-defined edges. The evolution after surgery was entirely satisfactory, with no complications or recurrences in the 24 months following the procedure.
