Summary
Peri-prosthetic ossification, particularly grades III and IV, can cause hip joint stiffening and handicap. Surgical intervention combined with radiotherapy, alongside preventative anti-inflammatory drugs and diphosphonates for at-risk patients, is recommended.
Area of Science:
- Orthopedic Surgery
- Radiology
- Rheumatology
Background:
- Peri-prosthetic ossification is a complication following hip arthroplasty.
- Grades I and II ossification are common and do not impact outcomes.
- Grades III and IV ossification lead to significant joint stiffening and handicap.
Purpose of the Study:
- To analyze peri-prosthetic ossification, its risk factors, and management strategies.
- To evaluate the effectiveness of surgical treatment, radiotherapy, and prophylactic measures.
Main Methods:
- Retrospective analysis of 100 patients with hip prostheses.
- Classification of peri-prosthetic ossification into grades I-IV.
- Review of surgical interventions, radiotherapy protocols, and preventative treatments.
Main Results:
- 49 cases of ossification observed in 100 patients.
- 6 cases of grades III and IV ossification identified.
- Grades III and IV ossification led to progressive coxo-femoral joint stiffening within one year.
Conclusions:
- Re-operation is indicated for severe peri-prosthetic ossification (grades III and IV) to restore joint mobility.
- Surgical treatment should be complemented by radiotherapy.
- Prophylactic treatment with NSAIDs and diphosphonates is crucial for high-risk individuals.
