Abstract

Traumatic hip fracture-dislocations are associated with chondral and labral pathology as well as loose bodies that can be incarcerated in the hip joint. Incarceration, such as interposed labrum between acetabulum and femoral head that is not readily visualized preoperatively, is a rare but important cause of pain and can potentially be a source for early degeneration and progression to osteoarthritis. We present three cases, arthroscopic surgery of incarcerated acetabular osseo-labral fragment following reduction of traumatic hip fracture-dislocation.

  Fig. 1 A 24-year-old woman complained pain and snapping sensation in the left hip joint. (A) Preoperative plain anteriorposterior radiography of the pelvis shows asymmetry of the medial hip joint space and (B) computed tomography (CT) scan shows intra-articular bony fragment (arrow). (C) In arthroscopic findings, acetabular osseo-labral fragment is widely detached and incarcerated in the joint space (asterisk). (D) Postoperative plain radiography and (E) CT scan show concentric reduction and complete removal of bony fragment. (F) Inverted labral tear is refixed after reduction.

  Fig. 2 A 17-year-old man complained pain and limited range of motion in the left hip joint. (A) Preoperative plain anteriorposterior radiography of the pelvis shows asymmetry of the medial hip joint space and (B) computed tomography (CT) scan shows intra-articular bony fragment (arrow). (C) In arthroscopic findings, acetabular osseo-labral fragment is widely detached and incarcerated in the joint space (asterisk). (D) Postoperative plain radiography and (E) CT scan show concentric reduction and complete removal of bony fragment. (F) Inverted labral tear is refixed after reduction.

• 

  Fig. 3 A 54-year-old woman complained pain and limited range of motion in the right hip joint. (A) Preoperative plain anterior-posterior radiography and (B) computed tomography (CT) scan shows intra-articular bony fragment (arrows). (C) In arthroscopic findings, acetabular osseo-labral fragment is widely detached and incarcerated in the joint space (asterisk). (D) Postoperative plain radiography and (E) CT scan show concentric reduction and complete removal of bony fragment. (F) The incarcerated osseo-labral fragment is irreducible.
