Gluteus Maximus Transfer as an Augmentation Technique for Patients With Severe Abductor Deficiency of the Hip

Tijdschriftbijdrage - Tijdschriftartikel

Impaired abductor function of the hip following severe abductor deficiencies can be devastating for functionality and quality of life. Recently, gluteus maximus transfer has been proposed as a solution to these difficult problems. However, outcome results are sparse. The aim of this study was to evaluate the effects of gluteus maximus transfer on improvement of pain, disability, and quality of life in patients with severe hip abductor deficiencies. Gluteus maximus transfer was performed in 16 patients with severe disruption of the abductor muscles of the hip. Data were collected preoperatively and at 6 weeks, 3 and 6 months, and 1 to 2 years after surgery. The measurements pertained to complications, healing of the flap based on magnetic resonance imaging (MRI) findings (in 10 patients), evaluation of Trendelenburg gait and sign, and patient-reported outcome measures of pain, disability, and quality of life. Preoperatively, all patients had a positive Trendelenburg sign and reported severe pain at the level of the greater trochanter. At a mean follow-up of 20 months,the Trendelenburg sign was negative in 7 patients and the Trendelenburg gait had disappeared in 7 patients. There was an improvement in patient-reported outcome measures but not to a significant level except for the pain subscores. Two patients had a postoperative seroma that resulted in a visible bump on the lateral side. Seven of 10 repairs with MRI follow-up showed perfect ingrowth on MRI without signs of rerupture. Gluteus maximus transfer for abductor deficiency of the hip may be effective for pain relief and functional improvements.Most patients showed an improved quality of life but were not completely pain free.
