Gluteus Maximus Transfer for Hip Abductor Deficiency

Area of Science:

• Orthopedic surgery
• Hip biomechanics
• Musculoskeletal research

Background:

• Gluteus medius and minimus pathology causes lateral hip pain due to hip abductor deficiency.
• Gluteus maximus tendon transfer is an option for failed repairs or irreparable tears.
• Current techniques primarily use bone tunnel fixation.

Purpose of the Study:

• To describe a modified gluteus maximus tendon transfer technique.
• To enhance fixation strength and biomechanical stability of the tendon transfer.

Main Methods:

• A reproducible gluteus maximus tendon transfer technique is detailed.
• The modification involves adding a distal row to the tendon transfer.
• This aims to improve compression and fixation to the greater trochanter.

Main Results:

• The modified technique offers improved fixation compared to traditional methods.
• Enhanced compression of the tendon transfer to the greater trochanter is achieved.
• Improved biomechanical strength of the gluteal abductor transfer is anticipated.

Conclusions:

• The described distal row technique provides a reproducible method for gluteus maximus tendon transfer.
• This modification may offer superior fixation and biomechanical support for hip abductor deficiency.
• It presents a viable surgical option for managing lateral hip pain stemming from abductor dysfunction.
