Gluteus maximus transfer and mass graft (Capsulorraphy) in recurrent hip dislocation with the history of total hip replacement: A case series

Introduction: Post THR dislocation has been a significant complication that interferes with the patient's life. Detection of risk factors, careful planning, proper operative procedures, and patient education is essential to prevent the incidence of dislocation. Several operative measures have been studied to achieve this, including the use of mesh for soft tissue procedures and capsulorraphy. Case Presentation: A total of four patients is included in this case series. Two had a history of trauma that contributes to the necessity of the procedure while the other two had degenerative joint issues. All were operated by soft tissue procedure of gluteus maximus transfer as an abductor replacement and along with capsule augmentation using synthetic mesh as a synthetic capsule to strengthen and provide more stability. Discussion: The abductor strength from this gluteus maximus procedure is sufficient to stabilize the pelvis and prevent pelvic sag. The primary material of the mesh should produce inflammatory reaction so that a fibro capsular structure is formed surrounding the hip joint to add stability. Conclusion: The use of mesh in soft tissue procedures, such as capsulorraphy, with the addition gluteus maximus transfer may assist to prevent (re)dislocations of the hip. However, further study should be conducted to validate the routine use of mesh and gluteus maximus transfer to prevent dislocation after the procedure.
