We report the ten-year survival of a cemented

time of surgery, and compare the functional outcome with that of
patients aged >
55 years. The data were collected prospectively
and analysed using Kaplan-Meier survival statistics, with revision
for any reason, or death, as the endpoint. A total of 203 patients
aged <
55 years were identified. Four had moved out of the area
and were excluded, leaving a total of 221 TKRs in 199 patients for
analysis (101 men and 98 women, mean age 50.6 years (28 to 55));
171 patients had osteoarthritis and 28 had inflammatory arthritis.
Four patients required revision and four died. The ten-year survival
using revision as the endpoint was 98.2% (95% confidence interval
94.6 to 99.4). Based on the Oxford knee scores at five and ten years,
the rate of dissatisfaction was 18% and 21%, respectively. This
was no worse in the patients aged <
55 years than in patients
aged >
55 years. These results demonstrate that the

We present the case of a 63-year-old woman who sustained an acrylic cement burn of the sciatic nerve at hip replacement. She was treated by resection of the damaged segment and grafting. Electron microscopy showed that the nerve was nearly normal 1 cm from the
A prospective single-cohort study was designed to include 20 patients with enchondromas but was stopped because of poor early results. Four patients with an enchondroma, three in the proximal humerus and one in the distal femur, were treated by curettage and filling of the defect with Norian SRS

There have been comparatively few studies of the incidence of osteolysis and the survival of hybrid and cementless total hip replacements (THRs) in patients younger than 50 years of age. We prospectively reviewed 78 patients (109 hips) with a hybrid THR having a mean age of 43.4 years (21 to 50) and 79 patients (110 hips) with a cementless THR with a mean age of 46.8 years (21 to 49). The patients were evaluated clinically using the Harris hip score, the Western Ontario and McMaster Universities (WOMAC) osteoarthritis score and the University of California, Los Angeles (UCLA) activity score. Radiographs and CT scans were assessed for loosening and osteolysis. The mean follow-up was for 18.4 years (16 to 19) in both groups. The mean post-operative Harris hip scores (91 points versus 90 points), the mean WOMAC scores (11 points versus 13 points) and UCLA activity scores (6.9 points versus 7.1 points) were similar in both groups. The revision rates of the acetabular component (13% versus 16%) and the femoral component (3% versus 4%), and the survival of the acetabular component (87% versus 84%) and the femoral component (97% versus 96%) were similar in both groups. Although the long-term fixation of the acetabular metallic shell and the
