The Modified Dunn Subcapital Realignment Osteotomy for the Treatment of Moderate and Severe Slipped Capital Femoral Epiphysis; A Tertiary Referral Centres Experience
Description
In this presentation, Daniel Winsom discusses findings from his fellowship focused on Modified Dunn osteotomies, particularly in the context of treating slips, a common pathology in Australia linked to obesity and the Polynesian Aboriginal communities. He highlights the challenges of treating severe slips with pinning in situ, which is the gold standard but can be difficult and doesn't correct the underlying deformity. Winsom presents the results of a retrospective study over ten years, where they analyzed post-operative AVN rates following Modified Dunn surgeries, emphasizing the need for careful surgical technique to maintain blood supply to the femoral head.
Through clinical photographs and case studies, he illustrates the surgical process and various outcomes, revealing that the overall AVN rate was 17%, with higher rates in unstable versus stable hips. Winsom notes the importance of high-volume centers in performing such technically demanding procedures and expresses a desire to reduce AVN rates further, aiming for better outcomes through enhanced techniques and management strategies. The presentation concludes with a discussion on the importance of collaborative research efforts as they compare significantly with existing literature on AVN rates after similar procedures.
