Cementless arthroplasty with a distal femoral shortening for the treatment of Crowe type IV developmental hip dysplasia

Background:Severe developmental dysplasia of the hip is a surgical challenge. The purpose of this study is to describe the cementless arthroplasty with a distal femoral shortening osteotomy for Crowe type IV developmental hip dysplasia and to report the results of this technique.Results:The mean followup for the 12 hips was 52 months (range 36-82 months). The mean Harris hip score improved from 41 points (range 28-54) preoperatively to 85 points (range 79-92) at the final followup. The mean length of bone removed was 30 mm (range 25-40 mm). All the osteotomies healed in a mean time of 13 weeks (range 10-16 weeks). There were no neurovascular injuries, pulmonary embolism or no infections.Conclusion:Our study suggests that cementless arthroplasty with a distal femoral shortening is a safe and effective procedure for severe developmental dysplasia of the hip.

Total hip arthroplasty in adult patients who had developmental dysplasia of the hip

This study evaluated the hypothesis that the clinical results are equivalent in the group of patients with dysplasia, low dislocation, and high dislocation types using a contemporary technique for hip arthroplasty. The mean age of patients at the time of the index operation was 49.5 years (range, 29-61 years). Thirty patients (40 hips, 35%) had dysplasia, 22 (34 hips, 29%) had a low dislocation, and 24 (42 hips, 36%) had a high dislocation. The mean follow-up was 9.7 years (range, 6-14 years). In the high dislocation group, 7 hips (17%) had a revision of one or both component. In low dislocation group, 3 hips (9%) had a revision of one or both components. In the dysplastic group, 2 hips (5%) had a revision of one or both components.     

Early results of total hip arthroplasty in patients with developmental dysplasia of the hip compared with patients with osteoarthritis

We have investigated the results of primary total hip arthroplasty (THA) performed in patients with developmental dysplasia of the hip (DDH). Through the New Zealand Joint Registry, we identified all patients with DDH undergoing primary THA (n = 1205) and all patients with primary osteoarthritis (OA) undergoing primary THA (n = 40 589) between January 1, 1999, and December 31, 2008. Postoperative outcomes, baseline information, and operative characteristics were analyzed and compared between the DDH and the OA groups. There was no significant difference in Oxford Hip Score or revision rate between the 2 groups. Our results support THA as a successful surgical option in the management of degenerative arthritis in DDH, with comparable functional outcomes and revision rates to THA performed for primary OA.

Total hip arthroplasty (S-ROM stem) and subtrochanteric osteotomy for Crowe type IV developmental dysplasia of the hip

Background:

Developmental dysplasia of the hip (DDH) in adults with severe pain and disability is best treated by total hip arthroplasty (THA). The purpose of this study was to retrospectively evaluate the outcomes of subtrochanteric shortening osteotomy combined with THA using S-ROM stem for those severe patients with a special focus on the effect of two shapes in the subtrochanteric osteotomy ends: Oblique and transverse.

Materials and Methods:

Twenty one cases with mean age of 43.6 years who met inclusion criteria and were operated between February 2007 and February 2012 were included in the study. Those cases had been divided into two groups (oblique vs. transverse) and all records between the two groups were analyzed.

Results:

The Harris hip score significantly improved from 30.6 (range 18–59) preoperatively to 91.2 (range 87–98) postoperatively by the latest followup. Complications including one deep venous thrombosis, one intraoperative fracture of femur and two dislocations occurred while they were addressed properly afterward. The oblique group showed significant advantages in operative time, union time and additional fixation in comparison with the transverse group.

Conclusions:

In the primary THA for the treatment of irreducible DDH, subtrochanteric oblique osteotomy combined with the freely-rotatable S-ROM stem provided favorable short term outcomes by affording both morphological and functional advantages.     

Dislocation after total hip arthroplasty among patients with developmental dysplasia of the hip

The precise relationship between developmental dysplasia of the hip and dislocation among patients after total hip arthroplasty has not been well clarified. A total of 820 patients with developmental dysplasia of the hip who underwent total hip arthroplasty from January 2000 to December 2009 were categorized according to Crowe classification, and postoperative dislocation rates were analyzed among subgroups. The overall dislocation rate was 2.93%. No statistically significant differences in dislocation rates were observed between these with and without subtrochanteric osteotomy. Femoral head size was the only factor with significant difference between the dislocated and stable groups, especially when femoral head diameter increased from 28 to 32 mm. Of all dislocations, 69.6% were anterior dislocation, and the degree of cup anteversion and combined anteversion of anterior dislocators was higher than that of the posterior dislocators (P = .0082 and P = .001).
