Arthrodiastasis in the management of Perthes disease: a systematic review.

Abstract

This systematic review explores the relevant literature to assess the efficacy of the use of arthrodiastasis in the management of Perthes disease. Until this moment, arthrodiastasis is not well established for its use in Perthes disease as opposed to other containment procedures. Furthermore, there are no clear indications for its use in this disease. Twelve articles were matched to the inclusion criteria and all articles were reviewed and radiological and clinical data were collected and compiled. As regards the hip flexion range of motion, the average preoperative flexion range of motion was 55.32°, while the postoperative was 90°. The average preoperative hip abduction range of motion was 12.28° and postoperative was 35.28°. Mean preoperative hip internal rotation range of motion was 8.69° and postoperatively was 24.93°. Mean preoperative external rotation range of motion was 21.73°, while the postoperative range was 33.71°. Final Stulberg classification was ascertained showing most patients ending with stages two and three. Complications were also assessed with most of which being superficial pin tract infections. The use of arthrodiastasis is a valid treatment option for Perthes disease; however, more articles need to be produced showing comparative data of arthrodiastasis versus other containment procedures. Level of evidence - level 1: systematic review.
