Treatment of genu valgum by a novel percutaneous transverse metaphyseal osteotomy of the distal femur in children and adolescents.

Purpose: To evaluate the outcomes of a novel percutaneous medial supracondylar femoral osteotomy and above-knee cast technique in children and adolescents as a minimally invasive surgical intervention for treatment of genu valgum.

Methods: In this prospective study, 60 patients (70 knees) with a tibiofemoral angle more than 15° were treated with a novel medial percutaneous supracondylar femoral osteotomy and above-knee cast and followed up for an average of 29 months. The radiological outcome was measured with MAD, TFA, and mLDFA.

Treatment of non-united femoral neck fracture by a novel subtrochanteric angulation lateral translation valgus osteotomy (SALVA osteotomy).

Purpose: The ideal treatment of non-united and neglected fracture neck femur in the young adult still remains unclear and is characterized by many biological and biomechanical challenges.

Methods: Twenty-one patients with non-united or neglected fracture neck femur aged between 19 and 50 years were treated by a novel subtrochanteric valgus osteotomy and were followed up for a mean of 26.7 months.

Dynamic stabilization for degenerative diseases in the lumbar spine: 2 years results.

Following lumbar fusion, adjacent segment degeneration has been frequently reported. Dynamic systems are believed to reduce main fusion drawbacks. We conducted a retrospective study on patients with degenerative lumbar disease treated with posterior dynamic stabilization with monoaxial hinged pedicular screws and lumbar decompression.
