Leg length discrepancy is a common and not appreciated complication after THR. Unequal leg length may cause earlier implant wear, patient's dissatisfaction, impair patient's function or even some legal consequences for the surgeon. To achieve the final equal leg length after surgery one must comply with some rules: proper patient's examination, informing patient about possible leg length discrepancy, proper length measurement- both clinical and radiological after antero-posterior pelvis x-ray; proper radiological length measurements especially when some hip contractures are observed, appropriate implant selection, proper prosthesis templating. The intraoperative leg length measurement with some surgical or radiological devices is essential for leg equalization. Special operative techniques are necessary for leg lengthening or shortening without hip instability. Final leg length measurement after surgery is necessary to determine a rehabilitation program. |
