Insights
The Basic hip prosthesis demonstrated good mid-term outcomes in 417 patients, with improved hip function and acceptable complication rates. These results support the continued use of this implant in hip replacement surgery.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Hip replacement surgery is a common procedure for treating debilitating hip conditions.
- The Basic hip prosthesis is a widely used implant for total hip arthroplasty.
- Evaluating the long-term efficacy and safety of hip prostheses is crucial for patient outcomes.
Purpose of the Study:
- To assess the mid-term clinical and radiographic outcomes of the Basic hip prosthesis.
- To determine the complication rates associated with this implant.
- To provide evidence supporting the use of the Basic prosthesis in hip arthroplasty.
Main Methods:
- A retrospective study of 430 hip prosthesis implant procedures using the Basic prosthesis.
- A mean follow-up period of 6 years for 417 patients.
- Clinical assessment using the Harris hip score and radiographic evaluation for complications.
Main Results:
- Significant improvement in average Harris hip score from 35.7 preoperatively to 90.9 postoperatively.
- Thigh pain decreased from 6% at 2 years to 2% at 6 years.
- Radiographic findings included calcar resorption (22 cases) and heterotopic ossification (36%).
Conclusions:
- The Basic hip prosthesis shows favorable mid-term clinical results comparable to other studies.
- The complication profile, including calcar resorption and heterotopic ossification, is within acceptable ranges.
- The study supports the continued use of the Basic prosthesis in hip replacement procedures.
Abstract:
The Basic (IQL-Biomet, Valencia, Spain) hip prosthesis was used in 430 implant procedures, of which 417 had mean follow-up of 6 years. Radiographic follow-up was performed at 1, 3, 6, and 12 months postoperatively, and annually thereafter. The average Harris hip score improved from 35.7 preoperatively to 90.9 postoperatively. Clinical results after 2 years of follow-up showed 6% thigh pain, which decreased to 2% at 6 years. Radiographic evaluation demonstrated 22 cases of calcar resorption, 14% of which had distal pedestal formation. Heterotopic ossification was noted radiographically in 36%. These mid-term results obtained with the Basic prosthesis are similar to the findings of other series and warrant its use.
