Surgical Technique: Open Hip HS Allograft
Femoroacetabular impingement is a well-known cause of hip pain. When impingement is caused by a relative over-coverage of the femoral head, it is called pincer impingement. A possible treatment option consists of rim trimming. Pincer impingement is often associated with labral thinning and degeneration. If the labrum is not repairable, a labral reconstruction is needed to restore labral function.
The preferred surgical technique for a circumferential labral reconstruction is an open reconstruction using a hamstring allograft. A surgical dislocation is performed according to the technique described by Ganz et al. After performing the rim trimming, a reconstruction of the labrum using a semitendinosus allograft is performed. This graft is prepared and then fixed to the rim using bone anchors from anterior to posterior. Both ends of the graft are also firmly fixed to the transverse acetabular ligament. This reconstruction ensures a 360° repair of the sealing function of the labrum.
