Hip Squeaking
The aim of the study was to analyze the incidence of squeaking with ceramic-onceramic total hip arthroplasty (THA) after 10 years of follow-up and the potential complications that could occur related to this phenomenon. One hundred THAs implanted between November 1999 and December 2000 were evaluated. Incidence of squeaking was investigated clinically with a questionnaire. Implant positioning w...
متن کاملA Computational Analysis of Squeaking Hip Prostheses
A ceramic-on-ceramic (CoC) hip prosthesis with clearance is modeled as a multibody dynamics system for the purpose of studying hip squeaking. A continuous contact force model provides the intrajoint forces developed at the hip joint. Friction effects due to the relative motion are also considered. A FFT analysis of the audible sounds from CoC hip acceleration is carried out to analyze hip squea...
متن کاملThe role of patient factors and implant position in squeaking of ceramic-on-ceramic total hip replacements.
We investigated factors that were thought to be associated with an increased incidence of squeaking of ceramic-on-ceramic total hip replacements. Between June 1997 and December 2008 the three senior authors implanted 2406 primary total hip replacements with a ceramic-on-ceramic bearing surface. The mean follow-up was 10.6 years. The diagnosis was primary osteoarthritis in each case, and no pati...
متن کاملInfluence of prosthetic design on squeaking after ceramic-on-ceramic total hip arthroplasty.
Squeaky ceramic-on-ceramic (COC) total hips have received much recent publicity, and implant design may be implicated. We reviewed 270 consecutive COC total hip arthroplasties in 233 patients comparing 4 implant combinations representing 4 manufacturers. A cohort (n = 45) of Stryker Trident acetabular cups paired with Stryker Accolade femoral stems showed a dramatically higher incidence of "pro...
متن کاملPainful Hips In Children
The clinical challenge in paediatric hip pain is to distinguish urgent conditions such as infection of the hip joint from the more common irritable hip. Transient synovitis is one of the most common causes in children over 3 years of age but it has similar early symptoms to septic arthritis. This article offers a guide to assessment, an overview of common causes, and clarity around which childr...
