AI Article Synopsis
- * All surgical procedures used a cemented cup that was fully supported by an allograft, with 7 cases of failure primarily due to loosening or infections.
- * Notably, 13 out of the 20 patients maintained stable reconstructions without needing further surgery, indicating that this method is a viable option for large bone defects not suited for conventional repair techniques.
Article Abstract
We evaluated the use of a hemipelvic acetabular transplant in 20 revision hip arthroplasties with massive acetabular bone defects. We report 65% good intermediate-term results at a mean follow-up of 5 years (4-10 years). A cemented cup (without a reinforcement ring) was entirely supported by the allograft in all procedures. There were 7 failures (5 aseptic loosening and 2 deep infections). Two dislocations occurred but did not require acetabular revision. There were 2 cases in which moderate acetabular migration occurred but then stabilised and did not progress. Thirteen of 20 acetabular reconstructions did not require revision. We believe that these are satisfactory intermediate-term results for massive acetabular defects too large for reconstruction with other standard techniques.

Purpose: Many treatment options are available for the revision of large acetabular defects. Debate continues as to which technique is most effective. This meta-analysis aimed to determine the rates of failure of acetabular bone defects Paprosky type III or American Academy of Orthopaedic types III-IV treated with morselized allograft in association with cemented cup or cementless cup or reinforcement devices.

Article Synopsis
- The study looks at surgeries done on kids' hips after removing bone tumors, focusing on two methods: modular prostheses and allograft-prosthesis composites.
- Researchers wanted to find out how often kids needed more surgery and what kinds of problems happened after these two types of surgeries.
- Over 54 kids were treated from 2000 to 2021, with different methods used depending on their age and how well they responded to treatment.

Background: Two-stage exchange arthroplasty remains the gold standard for treating chronic hip periprosthetic joint infections. However, controversy remains regarding the optimal spacer type, particularly among patients with increased dislocation risk. This study reports on the outcomes of articulating hip spacers utilizing a single constrained-liner design.

Introduction: Granuloma formation following total hip arthroplasty (THA) can occur regardless of the bearing surface. In very rare cases, extensive granulomas mimicking tumors may develop which are known as pseudotumors. The aim of this study is to report on these rare yet complex situations to stimulate reflection in diagnostic and therapeutic approaches.
