Reconstruction for chronic dislocation of the hip

Area of Science:

• Orthopedic Surgery
• Biomechanical Engineering

Background:

• Chronic hip dislocation presents complex reconstructive challenges.
• Restoring normal hip biomechanics is crucial for long-term function.

Purpose of the Study:

• To evaluate a surgeon's hip reconstruction technique for chronic dislocation.
• To assess the restoration of hip biomechanical parameters and patient outcomes.

Main Methods:

• Analysis of 66 patients (84 hips) undergoing hip reconstruction.
• Long-term patient profiling (0, 10, 20 years) including pain, mobility, and active movement.
• Radiological assessment for loosening, migration, subsidence, and revision rates.
• Measurement of work done by active movement against gravity.

Main Results:

• Satisfactory outcomes were achieved despite a higher incidence of complications compared to primary hip arthroplasty.
• Demonstrated advantages of using a flanged cemented socket.
• Specific custom-made prostheses were utilized in certain cases.

Conclusions:

• Hip reconstruction for chronic dislocation can yield satisfactory results.
• Flanged cemented sockets offer demonstrable benefits in these complex cases.
• Careful patient selection and surgical technique are vital for successful outcomes.
