This study aims to assess prospectively whether measurement of perioperative Troponin T is a useful predictor of potential morbidity and mortality in patients undergoing surgery for fractured neck of femur. All patients aged 65 years and over presenting with a fractured neck of femur over a 4-month period were initially included. Exclusion criteria were renal failure, polymyositis and conservative fracture management. Troponin T levels were measured on admission, day 1 and 2 post-surgery. According to local protocol, a level of >0.03ng/mL was considered to be raised. Outcome measures adverse were cardiorespiratory events (myocardial infarction, congestive cardiac failure, unstable angina, major arrhythmias requiring treatment and pulmonary embolism), death and length of inpatient stay. 108 patients were recruited after application of the exclusion criteria. 42 (38.9%) showed a rise in Troponin T >0.03ng/mL in at least one sample. Of these, 25 (59.5%) sustained at least outcome complication, as opposed to 7 (10.6%) from the group with no Troponin T rise (p<0.001). The mean length of stay was 25.7 days for patients with elevated Troponin T levels, compared with 18.3 days in the normal group (p<0.012). There were 9 deaths in the raised Troponin group (21.4%), and 5 (7.6%) in the group with no rise (p<0.05). The principal causes of early death after hip fracture surgery are cardiac failure and myocardial infarction. Troponin T is a sensitive enzymatic marker of myocardial injury. The association between raised Troponin and hip fractures has not previously been made. In our series, 38.9% showed a perioperative Troponin rise. This was significantly associated with increased morbidity, mortality and longer hospitalisation. Many hip fracture patients appear to be having silent cardiorespiratory events, contributing significantly to perioperative morbidity. We recommend measurement of Troponin levels in all such patients to identify this risk and initiate appropriate treatment.

To investigate the proportion of dysplastic hips which are retroverted. We studied the radiographs of over seven hundred patients with dysplastic hips who had had a periacetabular osteotomy in the period 1984–1998. We excluded patients with neuromuscular dysplasia, Perthes’ disease of the hip, post-traumatic dysplasia and proximal focal femoral deficiency. We selected 232 radiographs of patients with congenital acetabular dysplasia. A number of parameters were measured including lateral centre-edge angle, anterior centre-edge angle, acetabular index of weight-bearing surface, femoral head extrusion index and acetabular index of depth to width. Also recorded were acetabular version and congruency between femoral head and acetabulum. The lateral centre-edge angle of Wiberg had a mean value of 6.4° (SD 8.9°), the mean anterior centre-edge angle was 1.3° (SD 13.5°) and the acetabular index of weight-bearing surface of the acetabulum had a mean value of 24.5° (SD 9.7°). The majority (192, 82.8%) of acetabula were anteverted as might be expected. However, a significant minority (40, 17.2%) were retroverted. The mean anterior centre-edge angle in retroverted hips was 6.7° (SD 9.4°) compared with 0.4° (SD 13.3°) in anteverted hips. The authors have shown that, in a typical group of patients with congenital acetabular dysplasia significant enough to warrant periacetabular osteotomy, the majority of hips as expected have anteverted acetabula. However, a significant minority are retroverted. This finding has an important bearing on the performance of the osteotomy. We have also found that most if not all the information required prior to and following periac-etabular osteotomy can be obtained from an orthograde view of the pelvis.
It is generally agreed that in acetabular dysplasia the acetabulum lies excessively anteverted. Although this is true for the majority of hips, we have found that in some patients with dysplastic hips, the acetabulum lies unexpectedly in retroversion.
