Treatment of delayed- and non-union of fractures using pulsed electromagnetic fields.

A prospective series of 32 consecutive patients, with 33 long-bone fractures suffering from delayed- or non-union were treated by pulsed electromagnetic fields (PEMF) or by PEMF with surgery. The management regime for the PEMF treatment was simpler and less rigid than that reported by Bassett et al. and our stimulation waveform was also different.

Delayed median nerve injury due to retained glass fragments. A report of two cases.

Two cases of delayed median nerve division after laceration of the wrist by glass are described. In both there was no neurological damage at the time of the original injury. However, retained fragments of glass were subsequently responsible for division of the median nerve in both cases and of the surrounding tendons in one.

Entrapment neuropathy of the superficial peroneal nerve. A bilateral case.

A 21-year-old female athlete presented with bilateral lumps in her calves which became painful on exercise. Exploration revealed entrapment of the superficial peroneal nerves. Her symptoms were relieved by fasciectomy.

Ruptured femoral vein. A complication of the use of gentamicin beads in an infected excision arthroplasty of the hip.

Despite widespread use of gentamicin beads in the treatment of chronic infections of bone and soft tissue, no serious complications have been reported. This report describes a rupture of the femoral vein which occurred during the attempted removal of a chain of beads after radical excision of a chronically discharging Girdlestone arthroplasty. The patient later had a disarticulation at the hip.

Osteoarthritis of the hip: the patient behind the disease.

Previous epidemiological studies suggested that patients with osteoarthritis (OA) of the hip might constitute a definable subset of the population with characteristics that predispose them to joint failure. To investigate this possibility a comparative study of somatotype, bone density, disc degeneration, polyarticular joint degeneration, and soft-tissue calcification was carried out in 3 groups of individuals: (1) patients presenting with OA of the hip; (2) patients with acute femoral neck fracture; (3) healthy controls. OA of the hip was rare in patients with femoral neck fracture; conversely, patients with coxarthrosis did not have the low values for bone density seen in the fracture group.

The use of suction drainage in the operation of meniscectomy.

A prospective trial has been carried out to determine the value of suction drainage in the operation of meniscectomy. One hundred operations were analysed, in half of which drains had been used. The use of the drain could not be shown to result in any sustained advantages.

Appendicitis and mimicking conditions. A prospective study.

A prospective study of 444 consecutive patients diagnosed as having acute appendicitis was carried out in a district general hospital. The appendix was acutely inflamed, gangrenous, or perforated in 346 patients. Diagnostic error, 22% overall, was twice as common in females as in males.
