ABSTRACT: The purpose of
this multicenter study was to evaluate the clinical performance of an ultrahigh
molecular weight polyethylene (UHMWPE) fiber cable for re-attachment of the
osteotomized greater trochanter in hip surgery. Included in the study were 85
hips that had undergone surgery with greater trochanter osteotomy, including 50
hip arthroplasty procedures and 35 hip osteotomies. The osteotomized greater
trochanter was reattached using one or more UHMWPE fiber cables. The bone union
and displacement of the greater trochanter were assessed in radiographs for up
to 12 months after surgery. Non-union of the osteotomy site occurred in 4.7% of
the cases. In approximately 90% of the cases, displacement was less than 2 mm at up to
12 months after surgery. The UHMWPE fiber cable was a good biomaterial for
reattaching the osteotomized greater trochanter and may also be an option for
osteosynthesis procedures.
