[Cases of complex endoprosthetic surgery of the hip joint]

Area of Science:

• Orthopedic Surgery
• Reconstructive Surgery

Background:

• Complex hip joint pathologies and trauma sequelae necessitate specialized surgical interventions.
• 140 complex endoprosthetic hip joint procedures were performed in 124 patients between 1988 and 2001.
• These cases represented 14.3% of all hip joint surgeries at the institution.

Purpose of the Study:

• To evaluate the outcomes of complex hip joint endoprosthetics, particularly focusing on a newly developed two-stage surgical method.
• To establish primary complex endoprosthetics as a distinct surgical category requiring specialized techniques and equipment.

Main Methods:

• A retrospective analysis of 140 complex hip joint endoprosthetic procedures in 124 patients.
• Application of a novel two-stage hip joint endoprosthetics method (Patent No 2173108 RF) in 16 patients.
• Post-operative follow-up ranging from 1 to 6 years, with results assessed using the Harris Hip Score.

Main Results:

• The study included 6 main patient groups with significant pathological changes requiring tailored surgical approaches.
• The developed two-stage method was applied to 16 patients, achieving excellent or good results in 14 (87.5%) cases.
• Patients undergoing this complex procedure had a mean age of 48.7, significantly younger than those receiving conventional primary endoprosthetics (mean age 68).

Conclusions:

• Primary complex hip joint endoprosthetics should be recognized as an independent surgical intervention type.
• The developed two-stage method offers a viable and effective solution for complex hip joint endoprosthetics.
• Successful outcomes necessitate specialized planning, surgical expertise, and advanced equipment for complex hip joint reconstructions.
