[Problems of hip arthrodesis (author's transl)]

Area of Science:

• Orthopedic Surgery
• Biomechanical Engineering

Background:

• Hip arthrodesis is a surgical procedure to fuse the hip joint.
• Various techniques exist, each with potential benefits and drawbacks.
• Assessing long-term outcomes and comparative effectiveness is crucial.

Purpose of the Study:

• To report on a follow-up study of 84 hip arthrodesis cases.
• To compare the outcomes of four different arthrodesis methods.
• To evaluate the long-term influence of hip fusion on the knee and lumbar spine.

Main Methods:

• Follow-up study of 84 patients undergoing hip arthrodesis.
• Application of four surgical techniques: nail-block, double-nail, cross-plate, and screw arthrodesis.
• Analysis of clinical outcomes and biomechanical impact on adjacent joints.

Main Results:

• Double-nail arthroplasty was discontinued in favor of total hip arthroplasty.
• Screw arthrodesis was abandoned due to suboptimal results.
• Nail-block and cross-plate arthrodesis demonstrated continued value, particularly for younger, working individuals.

Conclusions:

• Nail-block and cross-plate hip arthrodesis are effective for specific patient populations.
• These methods are particularly beneficial for young, active individuals awaiting total hip arthroplasty.
• Further investigation into the biomechanical effects on the knee and lumbar spine is warranted.
