    Derotation varus osteotomy improved outcomes for severe Perthes disease patients compared to nonoperative methods. Surgical treatment led to better clinical and radiological results, particularly for Catterall grade 4 hips.

    Area of Science:

    • Orthopedic Surgery
    • Pediatric Orthopedics
    • Pediatric Bone Diseases

    Background:

    • Perthes disease affects hip joint development in children.
    • Severe forms require effective containment strategies.
    • Previous treatments had variable success rates.

    Purpose of the Study:

    • To compare the efficacy of derotation varus osteotomy versus nonoperative methods for severe Perthes disease.
    • To evaluate clinical and radiological outcomes in both treatment groups.

    Main Methods:

    • Retrospective study of 44 patients with severe Perthes disease.
    • Group 1: 32 hips treated with derotation varus osteotomy.
    • Group 2: 12 hips treated with casts and splints.

    Main Results:

    • Operated group showed superior clinical outcomes compared to the nonoperated group.
    • 75% of operated hips had good to fair radiological results.
    • 41% of nonoperated hips had fair radiological results.

    Conclusions:

    • Derotation varus osteotomy is advantageous for severe Perthes disease, especially Catterall grade 4.
    • Surgical containment offers better outcomes than nonoperative management.
    • Radiological assessment methods are crucial for evaluating treatment effectiveness.
