Area of Science:

  • Orthopedic Surgery
  • Reconstructive Surgery

Background:

  • Acetabular bone deficiency presents a significant challenge in revision hip arthroplasty.
  • Effective reconstruction techniques are crucial for restoring hip function and stability.

Purpose of the Study:

  • To evaluate the clinical and radiographic outcomes of acetabular revisions using an acetabular roof reinforcement ring with a hook (ARRRH).
  • To assess the efficacy of ARRRH combined with morsellized bone graft in cases with moderate-to-severe acetabular bone deficiencies.

Main Methods:

  • Retrospective evaluation of 37 acetabular revisions utilizing the ARRRH technique.
  • Assessment of patient demographics (average age 52.4 years) and follow-up duration (mean 4.5 years).
  • Clinical outcomes measured by the Harris hip score; radiographic assessment of bone graft incorporation.

Main Results:

  • Significant improvement in mean Harris hip score from 49 preoperatively to 87 postoperatively.
  • Complete radiographic incorporation of bone graft in all 37 cases.
  • Reported complications included hip dislocation (3), greater trochanter nonunion (1), infection (1), donor site discomfort (3), and hook failure (2).

Conclusions:

  • The acetabular roof reinforcement ring with a hook (ARRRH) is a valuable surgical option for acetabular revision.
  • This technique, when combined with morsellized bone graft, demonstrates successful outcomes in patients with moderate-to-severe acetabular bone deficiencies.
  • While effective, potential complications should be considered during surgical planning and patient selection.
