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.
To study possible neurologic complications, five lambs were operated on by sublaminar wiring at the thoracolumbar spine. Monitoring of the central motor pathway was carried out by percutaneous electrostimulation. A comparative anatomic study was designed to compare the magnitude of the spinal canal and the area occupied by the spinal cord at the low thoracic and lumbar level in 15 lamb, 8 pig, and 8 human spines. The following parameters were measured by slide caliper: the anteroposterior diameter of the spinal canal and the spinal cord, the length and thickness of the laminas, and the distance between each consecutive lamina. All five operated lambs showed major neurologic deficits after surgery. The results of the anatomic study suggest that there exists in humans a sufficiently ample "safety zone" that permits wire insertion without risking injury to neurologic structures. Such a "safety zone" is nonexistent in lambs and pigs unless an extensive laminectomy is performed to decrease the depth of wire penetration.
A 14-year-old boy had a congenital shortening of the first right metatarsal bone, with overloading of the central metatarsals and medial deviation of the second toe. A percutaneous osteotomy and slow distraction by an external fixator for 10 weeks lengthened the bone from 32 mm to 60 mm. After the distraction, a bone graft was performed, and tenotomies and a capsulotomy corrected a threatening subluxation. Consolidation of the lengthening focus required 16 weeks.
