Non-union following bilateral simultaneos Ganz trochanteric osteotomy. | LitMetric

AI Article Synopsis

  • A study involving 13 patients who had bilateral hip resurfacing showed a higher risk of complications compared to 139 patients who had unilateral surgeries, with 32% of the bilateral group experiencing symptomatic non-unions.
  • Statistical analysis revealed a significant difference in non-union rates, indicating that bilateral procedures have less favorable outcomes than unilateral ones (P=0.0004).
  • The findings suggest that if bilateral hip arthroplasty is performed, patients should remain non-weight bearing for 6 weeks post-surgery to help ensure better healing and reduce complications.

Article Abstract

Between January 2003 and December 2004, 13 patients underwent bilateral resurfacing arthroplasty via a Ganz trochanteric osteotomy. This bilateral group was mobilised fully weight-bearing with crutches. During the same period 139 Ganz trochanteric osteotomies were performed for unilateral hip resurfacing. These patients were mobilised with crutches, weight-bearing up to 10 kg on the operated leg. Nine osteotomies (32%) in the bilateral group subsequently developed a symptomatic non-union requiring revision of fixation. This compares with 10 patients (7%) in the unilateral group. Applying the Fisher's exact test, the difference reached significance (P=0.0004). In two patients a second revision was required to achieve union. In one patient, revision of trochanteric fixation precipitated a deep infection. Protected weight-bearing following a Ganz trochanteric osteotomy is important to the success of the procedure. Simultaneous bilateral hip arthroplasty through a Ganz approach should be avoided. If it is undertaken, we recommend that patients should be non weight-bearing for 6 weeks following surgery. Non-union following a Ganz trochanteric osteotomy for arthroplasty carries a significant morbidity.
