Background Total hip replacement for high dislocation of the hip presents some difficulties, considering patients' young ages, the abnormal hip anatomy and the high rate of complications. In this study, we present our experience in terms of clinical and radiological results in the treatment of Crowe type IV hips with subtrochanteric femoral shortening osteotomy and cementless total hip replacement. Materials and Methods We retrospectively reviewed 15 patients with Crowe type IV hip dysplasia (two bilateral cases for a total of 17 hips) treated with cementless total hip replacement associated with shortening subtrochanteric osteotomies (nine transversal and eight Z-shape osteotomies) between March 2000 to February 2006. The mean follow-up was 88 months (range 63-133). Harris hip score, leg length discrepancy, neurological status, union status of the osteotomy and the component stability were the criteria of the evaluation. All complications were noted. Results The mean HHS improved from 38.3 (range 32-52) to 85.6 (range 69-90). The mean preoperative leg length discrepancy was of 45 mm (range 38-70) and reduced to a mean of 12 mm (range 9-1.6) postoperatively. All osteotomies resulted healed at an average of 12.3 weeks (range 10-15). No cases of delayed union or nonunion were detected. Two patients (11%) showed early symptoms of sciatic nerve palsy which resolved uneventfully in 6 months. There was no migrations and none of the implants required revision. Conclusions Cementless THA with shortening subtrochanteric osteotomy is an effective method in the treatment of patients with Crowe type IV development dysplasia of the hip. Level of evidence IV.

We conclude that in complicated non-unions, the use of blade plate and bone strut allograft has a definite positive role in the management of such cases.

Introduction:Humeral shaft fractures are quite common in orthopedics and represent 1-3% of adult fractures. The surgical treatment is the a better choice in order to obtain a reduction and stable alignment and to prevent the complications. The goal of this study was to compare the three techniques (IMN, LCP and EF) in the treatment of diaphyseal fractures of the humerus in the adult patient.Materials and Methods:We examined 79 patients with diaphyseal fractures of the humerus. 32 were treated with plaque (LCP), 26 with intramedullary nail (IMN) and 21 with eternal fixer (FE) The clinical and radiographic follow-up was done at 1.3, 6 and 12 months. As rating scales we used the ASES and SF-36. We recorded all the complications.Results:The median follow-up was 11.5 months (9-16). The operative time was significantly smaller in the case of FE (47 ‘) with a statistically significant difference compared with other techniques. Even the blood loss was lower in the case of FE (60ml), compared to nails (160ml) and LCP (330ml) p <0.05. We had no differences in the duration of hospitalization and the ASES SF-36 score. We had 2 cases of non-union in the LCP group, 1 case in the IMN group and no cases in the FE group. In IMN group we had one case of radial transient paralysis. We did not have any deep infection, in the FE group 8 patients we had superficial secretions from pins.Conclusion:From the results of our study, it is clear that the treatment of humeral shaft fractures guarantee overlapping results with the use of plates, of intramedullary nails, or with the external fixator. Consequently, the choice of which technique to use should be determined based on the experience of the operator and patient compliance.
