[Total hip arthroplasty for non-functional bony ankylosed hip in young and middle-aged patients]
Insights
Total hip arthroplasty (THA) effectively treats young and middle-aged patients with non-functional bony ankylosed hips. This surgery significantly improves hip function and mobility, with excellent and good outcomes in 84.2% of cases.
Area of Science:
- Orthopedic Surgery
- Arthroplasty
- Hip Reconstruction
Background:
- Non-functional bony ankylosed hip presents significant mobility challenges.
- Young and middle-aged patients with hip ankylosis require effective surgical solutions.
Purpose of the Study:
- To evaluate the efficacy of total hip arthroplasty (THA) in young and middle-aged individuals suffering from non-functional bony ankylosed hips.
Main Methods:
- Retrospective analysis of 14 cases (19 hips) undergoing THA between January 2010 and March 2013.
- Patients aged 23-58 years with diverse etiologies including tuberculosis, ankylosing spondylitis, and arthritis.
- Pre- and post-operative Harris hip scores were compared, with an average follow-up of 2.2 years.
Main Results:
- Significant improvement in Harris hip scores from 24.368 ± 7.625 pre-operatively to 86.837 ± 7.742 post-operatively (P = 0.000).
- An excellent and good outcome rate of 84.2% was achieved.
- No major complications like neurovascular injury, dislocation, or infection were reported; prosthesis positioning was satisfactory on X-ray.
Conclusions:
- Total hip arthroplasty (THA) is a safe and effective treatment for non-functional bony ankylosed hips in younger and middle-aged populations.
- The procedure leads to substantial functional recovery and improved quality of life.
- THA offers a viable option for restoring mobility and function in this challenging patient group.
Objective:
To explore the effectiveness of total hip arthroplasty (THA) for non-functional bony ankylosed hip in young and middle-aged patients.
Methods:
Between January 2010 and March 2013, 14 cases (19 hips) of non-functional bony ankylosed hip were treated by THA. There were 9 males and 5 females, aged 37.5 years on average (range, 23- 58 years). The left hip was involved in 6 cases, the right hip in 3 cases, and bilateral hips in 5 cases. The causes were tuberculosis in 2 patients, ankylosing spondylitis in 5 patients, traumatic arthritis in 5 patients, osteoarthritis in 1 patient, and suppurative infection in 1 patient. The disease duration was 7-18 years with an average of 8.9 years. Flexion stiffness was observed in 10 hips, flexion abduction stiffness in 6 hips, and flexion adduction shortening stiffness in 3 hips. Only 5 patients could walk with a crutch before operation. Harris hip score was 24.368 ± 7.625.
Results:
The average operation time was 63.4 minutes (range, 50-90 minutes). The average intraoperative blood loss was 196.8 mL (range, 100-400 mL). Patients obtained primary healing of incision; no complication of neurovascular injury, fracture, joint dislocation, or infection occurred. All patients were followed up 2.2 years on average (range, 1 year to 4 years and 3 months). The Harris score was 86.837 ± 7.742 at last follow- up, showing significant difference when compared with preoperative score (t = -41.956, P = 0.000). The results were excellent in 5 hips, good in 11 hips, fair in 2 hips, and poor in 1 hip, with an excellent and good rate of 84.2%. All patients could basically take care of themselves; 2 patients could walk with crutch, and the other patients could walk without crutch. X-ray films showed that prosthesis was in good position; no shifting, loosening, or sinking was found. Heterotopic ossification occurred in 2 hips.
Conclusion:
THA is an effective surgical approach to treat non-functional bony ankylosed hip in young and middle- aged patients.
