40 patients with dislocated bimalleolar and trimalleolar ankle fractures took part in this randomized study. All ankles were operated on using cerclage, staples and pins. Active ankle movement with weight bearing in an orthosis was compared with active ankle movement without weight bearing using a dorsal splint. Stereophotogrammetric analysis showed small(More)
A prospective randomized study was performed comparing immediate and late weight bearing in 53 dislocated bimalleolar and trimalleolar fractures. Using cerlage, staples, and pins (Cedell 1967), an exact reconstruction of the ankle mortise was achieved in 41/53 ankles. At follow-up after 3 and 6 months, the two groups were equal regarding clinical results.(More)
BACKGROUND Periprosthetic bone loss occurs around uncemented femoral stems and may be influenced by the stem size. PATIENTS AND METHODS We studied 138 consecutive patients, 3 (2-7) years on average after a total hip arthroplasty operation (THA) for unilateral osteoarthritis with the Bi-Metric uncemented femoral stem. We analyzed Harris hip score and bone(More)
Fifty-one patients with dislocated lateral malleolar fractures took part in this prospective randomized study. Active ankle movements with weight bearing in an orthosis were compared with active ankle movements without weight bearing using a dorsal splint. By using cerclage, staples, and pins (Cedell 1967), an exact reconstruction of the ankle mortise was(More)
BACKGROUND Bone loss leading to late-occurring periprosthetic femoral fracture is a mode of failure in cementless total hip arthroplasty. The aim of this trial was to investigate the effect of a bisphosphonate, risedronate, on femoral periprosthetic bone resorption following total hip arthroplasty in patients with osteoarthritis of the hip. METHODS We(More)
To analyze postoperative fracture stability and late ankle mortise mobility, 46 lateral malleolar and 53 bimalleolar ankle fractures were randomly separated to either early or late weight-bearing groups and followed for 18 months. Internal fixation with cerclage wires, staples, and pins were used. Better clinical results were found among the lateral(More)
In 7 adult volunteers, a roentgen stereophotogrammetric technique was used to analyze the tibiofibular relationship during active unloaded movements of the ankle. The greatest movements were observed during plantar to dorsiflexion with an average widening of the ankle mortise of 1.0 mm and an average dorsal translation of the fibula of 0.9 mm. No(More)
Fifty-three patients with dislocated lateral malleolar fractures were randomly selected after operation for either active ankle movement and weight bearing in an orthosis or no ankle movement but weight bearing in a walking cast. At follow-up examinations after three, six, and 18 months, no differences were found between the groups except for a better(More)
The bone mineral content across the calcaneus was measured by gamma absorptiometry in 82 patients with operated on ankle fractures. A mean deviation in bone mineral content between the injured and the uninjured leg of 6 percent was found. Early weight bearing in a walking cast or brace did not influence the process of postfractural osteopenia. Compared with(More)
STUDY DESIGN A retrospective analysis of records and radiographs in five patients who developed acute cauda equina syndrome after surgery for lumbar disc herniation. OBJECTIVES To postulate as a possible pathophysiologic mechanism the venous congestion caused by preexisting spinal stenosis and to present a management plan: extended decompression within 48(More)
