Hip Replacement Arthroplasty (Subscribe)  

Incidence of sciatic &/or femoral palsies after THR ranges from 1-3%;
- incidence of nerve palsy is 1-2% of primary total hip replacement, 3-4% after revision, and 5-6% in THR for congenitally dislocated hips;
Wheeless' Textbook of Orthopaedics

Primary hip replacement requires careful patient selection, a knowledge of available prostheses, thorough pre-operative planning, familiarity with surgical exposures and sufficient manual dexterity to carry out the procedure. The aim of hip replacement is to restore the biomechanics of the diseased joint as closely as is practical. Failure to observe...

Intraoperative frozen section (FS) consultation is used in evaluating possible infection in cases of hip and knee revision arthroplasty, serving as an adjunct to preoperative and intraoperative studies. We examined our experience for more than 11 years to determine if FS examination had value when sections were sent unselectively. As...
