Satisfactory results seen after Ganz surgical hip dislocation for Pipkin fractures
Satisfactory results were seen after safe Ganz surgical dislocation of Pipkin fractures in hips with no increase in osteonecrosis in patients who underwent early joint reduction, based on results of a prospective trial.
Researchers studied 28 patients with type I or type II Pipkin fractures, who underwent closed reduction within 6 hours of injury. At 6 weeks, 12 weeks and every 6 months thereafter, until final follow-up, investigators radiographically assessed the patients. At the last follow-up, patients underwent functional assessments with the Merle d’Aubigne scores and Oxford hip scores (OHS). The mean follow-up was 36 months.
Investigators also used logistic regression analysis to determine the influence the procedure had on the timing of degenerative arthritis occurrence and functional outcomes.
Results showed all fractures were fixed internally and all osteotomies unified without the need of additional interventions. There was also no evidence of osteonecrosis on radiographs at follow-up. The mean modified Merle d’Aubigne score was 16.53 points and mean OHS was 42.65 points. Investigators noted patients with degenerative arthritis, patients with labral injury and patients with residual chondral effects had significantly lower Merle d’Aubigne scores.
According to results from the regression analysis, open surgery timing did not have an effect on the time when degenerative arthritis occurred or on the functional outcomes. ‒ by Monica Jaramillo
