Electroacupuncture in the treatment of a ganglion of the wrist--a case report.

A ganglion is a cystic swelling that occurs most commonly in women. Recurrence is possible after conservative or surgical treatment. A novel method of therapy, electroacupuncture stimulation, was performed in a 53 year old woman with a large, recurrent dorsal wrist ganglion. After treatment it rapidly disappeared and there was no recurrence during the one year follow-up period. Although the mechanism is obscure, it is our impression that electroacupuncture may have a local action on such cysts in addition to needle drainage.

[Tibial osteomyelitis following intraosseous infusion: a case report].

Fluids, medications, and blood products can be rapidly administered via intraosseous infusion under emergency conditions, particularly to pediatric patients aged from 0 to 2 years. A five-month-old infant who had been hospitalized with a diagnosis of sepsis developed swelling and hyperemia at the infusion site 10 days after an intraosseous infusion in the right proximal tibia. Physical examination showed a serous discharge from a fistula on the anteromedial side of the right proximal cruris. Plain radiographs demonstrated periosteal reaction in the right tibia and osteolytic areas in the proximal metaphysis. With a diagnosis of acute osteomyelitis, drainage and medullary irrigation were performed and parenteral antibiotic treatment was initiated. Cultures from the surgical site yielded Candida albicans, upon which fluconazole (8 mg/kg) treatment was administered for four weeks. A complete clinical and radiographic improvement was observed at the end of a 12-month follow-up.

A morphometric study on the humerus for intramedullary fixation.

In recent years, the popularity of intramedullary humeral nailing is on the rise in spite of its handicaps. There are many problems in intramedullary humeral stabilization because of the anatomic structure of the bone. We performed various methods and measurements to determine shape, length and diameter and curvature of the medullary canal of the humerus in 57 human dry cadaver bones. Anterior angulation with an average of 21 cm apart from greater tubercle was found at 1/3 distal part. Mean degree of angulation was 9 degrees (max: 15, minutes: 5, S.D.: 2.84). Humerus bones with septal aperture (supratrochlear foramen) at the fossa coronoidea were observed to have very narrow medullary canal. The best point for nail insertion was found to be an area on the line from greater tubercle anteromedially to caput humeri. This study revealed that carefully evaluated structure of humeral medullary canal and various congenital constructions such as septal aperture, and correct selection of a nail with proper length and diameter are essential for successful nailing.

[Comparison between fixation with Herbert screws and Kirschner wires in the treatment of scaphoid pseudoarthrosis].

OBJECTIVES: To compare the treatment results of patients with scaphoid pseudoarthrosis, who were treated by autogenous cancellous bone grafting followed by fixation with Herbert screws or Kirschner wires. METHODS: The study included 19 men (mean age 28 years, range 20 to 41 years) who were treated for scaphoid pseudoarthrosis and had a minimum follow-up of 12 months. Treatment was comprised of autogenous cancellous bone grafting and fixation with Herbert screws (n=10) or Kirschner wires (n=9). Fifteen right and four left hands were affected. The mean duration between the traumatic event and surgery was 20 months (range 3 to 72 months). Fractures were localized in the proximal pole (n=4, 21%), waist (n=13, 68%), and in the distal pole (n=2, 11%). The mean follow-up was 16 months for Herbert screws, and 21 months for Kirschner wires. RESULTS: None of the patients exhibited a loss in range of motion of 10 degrees or more. The mean time to union was six months (range 3 to 20 months) with Herbert screws and eight months (range 4 to 22 months) with Kirschner wires. All patients had union with Kirschner wires, whereas non-union occurred in three patients with Herbert screws, two of whom had had proximal pole fractures. Radiologic outcome was significantly different between the two groups (p<0.01). CONCLUSION: Because of good vascularity and union potential, scaphoid pseudoarthrosis can be successfully treated by an appropriate surgical technique using autogenous cancellous grafting independent of fixation materials.

Calcaneal brown tumor with primary hyperparathyroidism caused by parathyroid carcinoma: an atypical localization.

Brown tumors are one of the characteristics of primary hyperparathyroidism, although, in some cases, they are noted with secondary hyperparathyroidism as well. The authors present a case of a 50-year-old woman with primary hyperparathyroidism caused by parathyroid carcinoma with an unusual location of a brown tumor in the calcaneus. She first presented with pain and swelling over the heel and ankle, and the diagnosis was suspected by radiographs. Biopsy of the calcaneal lesion confirmed a brown tumor. After the parathyroid lesion was removed surgically, her symptoms were relieved. The calcaneal lesion was treated with immobilization of the foot.
