Summary
Leg length discrepancy after total hip replacement (THR) is common. Achieving equal leg length requires careful pre-operative assessment, intraoperative measurements, and specific surgical techniques to avoid complications and ensure patient satisfaction.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Leg length discrepancy is an underrecognized complication following total hip replacement (THR).
- This complication can lead to earlier implant wear, patient dissatisfaction, functional impairment, and potential legal issues for surgeons.
Purpose of the Study:
- To outline the essential steps and considerations for achieving equal leg length after THR.
- To emphasize the importance of meticulous measurement and surgical technique in preventing and managing leg length discrepancies.
Main Methods:
- Comprehensive pre-operative patient examination and informed consent.
- Accurate clinical and radiological (antero-posterior pelvis X-ray) length measurements, accounting for hip contractures.
- Appropriate implant selection, prosthesis templating, and intraoperative measurements using specialized devices.
- Application of specific surgical techniques for limb lengthening or shortening while maintaining hip stability.
Main Results:
- Adherence to a systematic approach, including detailed pre-operative planning and intraoperative adjustments, is crucial for successful leg length equalization.
- Meticulous measurement and technique minimize the risk of complications associated with unequal leg length post-THR.
Conclusions:
- Achieving equal leg length after THR is a multi-faceted process requiring careful attention to detail at every surgical stage.
- Final post-operative measurement is vital for guiding the patient's rehabilitation program and optimizing functional outcomes.
