Summary
The protrusio socket technique for total hip arthroplasty effectively treats chronic hip dislocation and subluxation. This surgical method yielded excellent outcomes in most patients, though obesity and osteopenia are contraindications.
Area of Science:
- Orthopedic Surgery
- Arthroplasty Research
Background:
- Chronic hip dislocation and subluxation present significant challenges in total hip arthroplasty.
- Existing techniques may have limitations in addressing these complex hip instability issues.
Purpose of the Study:
- To evaluate the efficacy of the protrusio socket technique in managing chronically dislocated or subluxated hips.
- To assess the long-term outcomes and identify potential contraindications for this specific arthroplasty procedure.
Main Methods:
- A retrospective case series involving twenty-two patients with chronic hip instability.
- Surgical implantation of the protrusio socket technique for total hip arthroplasty.
- Clinical and radiographic follow-up ranging from sixteen to fifty-nine months.
Main Results:
- The protrusio socket technique demonstrated high effectiveness in treating chronic hip dislocation and subluxation.
- Excellent surgical outcomes were achieved in seventeen out of twenty-two hips.
- Two hips did not achieve the desired excellent results.
Conclusions:
- The protrusio socket technique is a highly effective surgical option for chronic hip instability requiring total hip arthroplasty.
- Conditions such as obesity and systemic osteopenia (e.g., rheumatoid arthritis) are identified as contraindications for this procedure.
