Navigation for total hip arthroplasty
Despite increasing advantages in biomaterials, prosthetic designs, and implant fixation, clinical outcome of total hip arthroplasty (THA) has 10% failure rate after 10 years. Component malposition is well known to be responsible for instability, impingement, excessive wear and early loosening. Computer-assisted procedures are expected to improve the accuracy of the components positioning and al...
متن کاملHybrid SPECT/CT for the assessment of a painful hip after uncemented total hip arthroplasty
BACKGROUND The diagnosis of hip pain after total hip replacement (THR) represents a highly challenging question that is of increasing concern to orthopedic surgeons. This retrospective study assesses bone scintigraphy with Hybrid SPECT/CT for the diagnosis of painful THR in a selected cohort of patients. METHODS Bone SPECT/CT datasets of 23 patients (mean age 68.9 years) with a painful hip af...
متن کاملReverse hybrid total hip arthroplasty
Background and purpose - The use of a cemented cup together with an uncemented stem in total hip arthroplasty (THA) has become popular in Norway and Sweden during the last decade. The results of this prosthetic concept, reverse hybrid THA, have been sparsely described. The Nordic Arthroplasty Register Association (NARA) has already published 2 papers describing results of reverse hybrid THAs in...
متن کاملHybrid or reverse hybrid for total hip arthroplasty?
When reverse hybrid total hip arthroplasty (cemented thick all poly acetabular cup and uncemented hydroxyapatite coated femoral stem) was initiated in Turkey by this author in 1989, there was too much negative criticism.[1,2] The reason for preferring this option was earlier personal experience and the literature data.[3,4] Currently, to the author’s knowledge, there is no other orthopedic surg...
متن کاملClinical Study for Measurement of Stem Antetorsion during Total Hip Arthroplasty. Ct Free Navigation Vs G-guide
Implant positioning is one of the critical factors influencing the postoperative outcome in total hip arthroplasty (THA) [1.2]. In our previous study, we evaluated the Combined anteversion (CA) value in patients who underwent THA using an image-free navigation for the cup with manual adjustment of the stem. Consequently, the AT value showed wide variability [3].Since March 2013, we have measure...
