The hip suction seal plays a key role in distractive stability and maintenance of intra-articular fluid pressure of the hip. Preservation of the suction seal relies on the acetabular labrum and the congruence between the labrum and the femoral head-neck junction. During the treatment of cam-type impingement, iatrogenic over-resection in the femoral head-neck junction or labrum deficiency can cause loss of this suction seal. In this technical note, we describe a remplissage procedure performed in addition to labral reconstruction in a patient with loss of the suction seal due to a dysfunctional labrum and previous over-resection of a cam deformity.
髋关节的负压密封在髋关节的牵引稳定性和关节内液压维持中起着关键作用。负压密封的维持依赖于髋臼盂唇以及盂唇与股骨头-颈交界处的匹配度。在治疗凸轮型撞击症时,股骨头-颈交界处的医源性过度切除或盂唇缺损会导致这种负压密封丧失。在本技术说明中,我们描述了在一名因盂唇功能障碍和既往凸轮畸形过度切除导致负压密封丧失的患者中,除了盂唇重建之外还实施的一种填充手术。
