Aims. To assess the long-term effect of distal trochanteric transfer (DTT) on the clinical and radiographic outcomes of patients with Legg-Calvé-Perthes’ disease (LCPD) following a varus derotational osteotomy (VDRO). Patients and Methods. For this single centre cross-sectional retrospective study we analysed the data of 22 patients (24 hips) with LCPD who had greater trochanteric overgrowth (GTO), following a VDRO performed in our institution between 1959 and 1983. GTO was defined as an articular trochanteric distance (ATD) of < 5 mm. We compared the radiographic and clinical outcomes of patients who underwent DTT for GTO (ten patients, ten hips) with those who did not (12 patients, 14 hips). Age at presentation was 6.9 years (4 to 10) and 8.0 years (3.2 to 12) respectively. Symptoms associated with the hip and general quality of life were assessed using the Harris hip score (HHS) and the Short Form (SF)-36 questionnaires. Results. At long-term follow-up of the DTT group, the ATD was 21.7 mm (standard deviation (. sd. ) 9.8) and the centro-trochanteric distance (CTD) was 13.8 mm (. sd. 8.3). In the control group the ATD was -0.6 mm (. sd. 7.8) and the CTD was 32.5 mm (. sd. 10.2). These differences were statistically significant (p < 0.001). The mean HHS and SF-36 scores were 68.4 (. sd. 25.0) and 62.0 (. sd. 27.7) for the DTT group and 73.2 (. sd. 24.2) and 73.3 (. sd. 21.5) for the control group, respectively. There was no statistically significant difference in the HHS (p = 0.63) or SF-36 score (p = 0.25). There were four patients who had undergone hip arthroplasty in the DTT group (40%) and one patient (7.1%) in the control group (p = 0.07). The mean age at the time of arthroplasty was 45.3 years (42.1 to 56.5) and 43.6 years respectively. Six patients in the DTT group suffered from moderate to severe osteoarthritis (Tönnis grade 2 or 3) compared with eight patients in the control group (60% versus 57.1%, p = 0.61). Conclusion. Although DTT improved the radiographic results in the long-term follow-up of patients with GTO following VDRO, there was no clinical benefit seen in the HHS, SF-36 or incidence of osteoarthritis compared with patients who had not undergone DTT.

Aims

To examine the long-term outcome of arthrodesis of the hip undertaken in a paediatric population in treating painful arthritis of the hip. In our patient population, most of whom live rurally in hilly terrain and have limited healthcare access and resources, hip arthrodesis has been an important surgical option for the monoarticular painful hip in a child.

Aims. This study compared the long-term results following Salter osteotomy and Pemberton acetabuloplasty in children with developmental dysplasia of the hip (DDH). We assessed if there was a greater increase in pelvic height following the Salter osteotomy, and if this had a continued effect on pelvic tilt, lumbar curvature or functional outcomes. Patients and Methods. We reviewed 42 children at more than ten years post-operatively following a unilateral Salter osteotomy or Pemberton acetabuloplasty. We measured the increase in pelvic height and the iliac crest tilt and sacral tilt at the most recent review and at an earlier review point in the first decade of follow-up. We measured the lumbar Cobb angle and the Short Form-36 (SF-36) and Harris hip scores were collected at the most recent review. Results. During the first decade of follow-up, there was a greater increase in pelvic height in the children who had a Salter osteotomy (Salter, 10.1%; Pemberton, 4.3%, p < 0.001). The difference in the increase in pelvic height was insignificant at the most recent review (Salter, 4.4%; Pemberton, 3.1%, p = 0.249). There was no significant difference between the two groups for the lumbar Cobb angle, (Salter, 3.1°; Pemberton, 3.3°, p = 0.906). A coronal lumbar curve was seen in 41 children (97%), 30 of these had a compensatory curve. Sacral tilt was the radiographic parameter for pelvic imbalance that correlated most with the lumbar Cobb angle (Pearson correlation co-efficient 0.59). The Harris hip score and SF-36 were good and showed no differences between the two groups. Conclusion. In the long-term, we found no difference in the functional results or pelvic imbalance between Salter osteotomy and Pemberton acetabuloplasty in the management of children with DDH.

Purpose. To examine the effect of limb lengthening on the quality of life of people who have disproportionate short stature (DSS). Method. Thirteen previous patients, completed the SF-36, the Derriford Appearance Scale and participated in face to face semi structured interviews to establish the impact on their physical and social functioning, their present situation including employment, education, housing and leisure activities and their thoughts about whether they felt the treatment had been worthwhile. To increase understanding about the patient and family experience of limb lengthening, participants were asked about their memories of the procedure and the treatment period. Results. Much was learned about key areas such as pain control, pin site cleaning and physiotherapy. The importance of the role of families in supporting the patient through the treatment was strongly emphasised and how this was sometimes at the expense of siblings. Conclusions. Overall all participants were able to find some benefit to the procedure but they had mixed feelings about the outcome. There was evidence of benefit to some physical capabilities and confidence levels but there were areas where the situation was similar to those with DSS who had not had surgery e.g. bodily pain. It is acknowledged that this study has some methodological weaknesses which reduce the strength of the findings
