Leg length inequality, which is often considered to be a problem after
total hip replacement, can affect the outcome of the patient satisfaction.
Leg length inequality increased risk of dislocation, unaffected hip pain
leading the need for another surgery.
But in Japanese orthopedic settings,
these common complication following total hip arthroplasty can not
be informed precisely.
It is said because of lack of surgical technique,
positioning of the operation and the timing.
Nine hundred and eighty-seven cases of primary THA were studied
to address the clinical importance
of a leg length discrepancy following total hip arthroplasty. Another study
was undertaken to determine the effects of leg unequality on clinical outcomes
at up to 3 years follow-up.
A postoperative leg unequality of 10mm or more leads to poorer
functional results.
It does not happen a lot here in Japan, but still remains one of the
most common reasons in the U.S for litigation against the orthopedic community.
