Case ReportsPseudarthrosis resulting in complete paraplegia fifteen years after spinal fusion.
Paraplegia immediately following spinal fusion is a known problem. This case demonstrates the importance of long-term follow-up of fusion patients. Prompt attention must be given to any change in neurological status. A careful check must be made for pseudarthrosis and for secondary compression of the spinal cord as possible causes of neurological compromise.

Mechanical effects of reaming and implantation of acrylic cement into the medullary cavity of bones.
Changes in the mechanical properties of the rat femur caused by intramedullary application of bone cement were studied. In one group of animals reaming of the medullary cavity was performed, and bone cement was injected. In a control group only reaming was performed. ⋯ This may be attributed to more periosteal bone being deposited, as implantation of bone cement induced a significant increase in periosteal reaction. The elastic stiffness of the bone was not altered either by reaming or the implantation of bone cement. It is concluded that reaming and implantation of bone cement into the medullary cavity do not impair the mechanical properties of the femur in the young rat.

Randomized Controlled Trial Clinical TrialEarly results after Colles' fracture: functional bracing in supination vs dorsal plaster immobilization.
A randomized clinical study of functional bracing in supination (FUSU) versus dorsal plaster immobilization (DPI) was conducted in 145 patients with Colles' fracture. A dynamic wrist unit was developed and used in 68 patients allocated for FUSU. The anatomical end result after FUSU was excellent or good in 80% of the patients versus 64% after DPI (P less than 0.05), in particular due to less dorsal angulation (P less than 0.001) and less radial shortening. ⋯ At 6 months, 92% satisfactory results were achieved after FUSU versus 86% after DPI (P less than 0.05). Both anatomical and functional benefits were recorded in Frykman type V, VI, and VIII fractures and in the group of displaced intra-articular fractures. The functional benefit from FUSU is suggested primarily to be secondary to decreased fracture redislocation.
