The pelvic support osteotomy: indications and preoperative planning.

Pafilas D, Nayagam S - Strategies Trauma Limb Reconstr (2008)

Bottom Line: The pelvic support osteotomy is a double level femoral osteotomy with the objective of eliminating a Trendelenburg and short limb gait in young patients with severe hip joint destruction as a consequence of neonatal septic arthritis.We present an analysis of the preoperative assessment that will assist the surgeon to plan out the procedure.(b) Where should the second osteotomy be performed and what is the magnitude of varus and derotation desired at this level?

ABSTRACT
The pelvic support osteotomy is a double level femoral osteotomy with the objective of eliminating a Trendelenburg and short limb gait in young patients with severe hip joint destruction as a consequence of neonatal septic arthritis. The osteotomy has seen several changes and a brief historical overview is provided to set the evolution of the modifications of the procedure in context. We present an analysis of the preoperative assessment that will assist the surgeon to plan out the procedure. Specifically, we set out to answer the following questions: (a) Where should the first osteotomy be performed and what is the magnitude of valgus and extension correction desired at this level? (b) Where should the second osteotomy be performed and what is the magnitude of varus and derotation desired at this level?

The level of the second osteotomy is to allow the limb to return to a near parallel alignment to the contralateral normal side but leave a small residual overcorrection of valgus. The position of this osteotomy can be worked out as part of the preoperative plan using the equation described in the text where y = (x1 − x2)/sine θ

Fig7: The level of the second osteotomy is to allow the limb to return to a near parallel alignment to the contralateral normal side but leave a small residual overcorrection of valgus. The position of this osteotomy can be worked out as part of the preoperative plan using the equation described in the text where y = (x1 − x2)/sine θ

Mentions: We advocate the level of the distal osteotomy be placed such that after varus correction, the centre of the knee joint is the same distance from the midline of the body as compared with the contralateral side. This level can be determined using image manipulation software or using simple trigonometry (Fig. 7). In working out the level of the distal osteotomy, the following X-ray parameters are measured:Fig. 7
