Summary:. A 71-year-old man who had hip abductor insufficiency due to a chronic injury to the right superior gluteal nerve injury after lipoma resection presented to our outpatient clinic 1.5 years postoperatively with persistent pain, atrophy of the gluteus medius muscle, and Trendelenburg sign with a corresponding limp. A magnetic resonance imaging scan and neurophysiological diagnostics confirmed a chronic lesion of the superior gluteal nerve with completed reinnervation and absent pathological spontaneous activity, excluding neurosurgical options to restore hip abduction. Following interdisciplinary evaluation of the patient’s case, we performed a vastus lateralis transfer in May 2023 to stabilize the right hip joint. The entire vastus lateralis muscle was carefully freed from the surrounding tissue, and its attachment to the quadriceps tendon was separated. The proximal section of the lateral vastus was then fixed to the ilium and greater trochanter, while the muscle’s distal portion was sutured to a more proximal part of the quadriceps muscle. The postoperative course was without any complications, and the patient left the hospital with an abduction splint 10 days after surgery. When he presented to our outpatient clinic 10 weeks after surgery, he reported a significantly improved gait and reduction of pain. Trendelenburg sign was now absent, but right knee function was not impaired and the patient was able to ambulate without the regular need for an orthosis. A transfer of the vastus lateralis muscle is therefore a valuable option to restore hip abductor function in cases of chronic nerve lesions which exclude neurosurgical options.
