Avascular necrosis is a serious complication of slipped capital femoral epiphysis and is difficult to treat. The reported incidence varies from 3% to 47% of patients. The aims of treatment are to maintain the range of movement of the hip and to prevent collapse of the femoral head. At present there are no clear guidelines for the management of this condition and treatment can be difficult and unrewarding. We have used examination under anaesthesia and dynamic arthrography to investigate avascular necrosis and to determine the appropriate method of treatment. We present 20 consecutive cases of avascular necrosis in patients presenting with slipped capital femoral epiphysis and describe the results of treatment with a mean follow-up of over eight years (71 to 121 months). In patients who were suitable for joint preservation (14), we report a ten-year
Most surgeons favour removing forearm plates
in children. There is, however, no long-term data regarding the complications
of retaining a plate. We present a prospective case series of 82
paediatric patients who underwent plating of their forearm fracture
over an eight-year period with a minimum follow-up of two years.
The study institution does not routinely remove forearm plates.
A total of 116 plates were used: 79 one-third tubular plates and 37 dynamic
compression plates (DCP). There were 12 complications: six plates
(7.3%) were removed for pain or stiffness and there were six (7.3%)
implant-related fractures. Overall, survival of the plates was 85%
at 10 years. Cox regression analysis identified radial plates (odds
ratio (OR) 4.4, p = 0.03) and DCP fixation (OR 3.2, p = 0.02) to
be independent risk factors of an implant-related fracture. In contrast
ulnar plates were more likely to cause pain or irritation necessitating
removal (OR 5.6, p = 0.04). The complications associated with retaining a plate are different,
but do not occur more frequently than the complications following
removal of a plate in children.
