Between the 1950s and the 1980s, the incidence of forearm fractures increased in the city of Malmö. We have now collected data on all forearm fractures during 1991 and 1992 and compared them with previously published data from 1953-1957 and 1980-1981. During the 1990s, 1314 individuals with wrist fractures and 125 with shaft fractures were recorded. ⋯ In women, the increase in incidence of wrist fractures appears to have been interrupted, when comparing the years 1991-1992 and 1980-1981. Among men, the incidence of wrist fractures appears to be increasing, even after the 1980s. The reduction in incidence among women may partly be explained by warmer winters during 1991-1992.

We performed a retrospective survey of the clinical records and radiological examinations of 10 patients with a diagnosis of spinal epidural abscess, without spondylodiscitis. All patients had an acute onset of fever and local or radiating back pain. 3 patients had mild, and 1 patient severe neurological symptoms. The diagnosis and subsequent regression of the abscess after treatment were verified by MRI. ⋯ Blood cultures showed Staphylococcus aureus as the etiological agent in 8/10 patients. In 2 cases, no agent was found, probably due to ongoing antibiotic therapy when the cultures were taken. All patients were treated successfully using antibiotics alone, with complete regression of the neurological symptoms.

We studied 30 patients with arthrosis in one knee operated on with a cemented (n 26) or an uncemented total knee arthroplasty (TKA) (n 4). Full weight-bearing from the first postoperative day was allowed in all patients, and they received standard postoperative physiotherapy. 1 week prior to surgery, and after 3 and 6 months, isokinetic and isometric muscle strength in both legs were measured, using a Cybex 6000 dynamometer. Isokinetic tests showed a bilateral, significant, and progressive increase (30-53%) in flexor muscle strength most pronounced in the operated legs. ⋯ Isometric extension strength showed a temporary decrease at 3 months, which returned to the preoperative level. No significant change in isometric strength was observed in the contralateral legs. The knee pain during the muscle strength measurements decreased significantly from the preoperative level, which may indicate that the substantial pain relief within 3 months after a TKA is an important factor for evaluation of muscle strength.
