Total hip arthroplasty via muscle-sparing approaches is advocated and performed with increasing frequency. However, performing total hip arthroplasty through muscle-sparing approaches may require a more forceful retraction, which in turn may damage the muscles which the less invasive approach intended to preserve. We report on the rupture of the piriformis muscle during primary total hip replac...

The purpose of the study was to assess the safety of Intra-articular steroid hip injections (IASHI), prior to ipsilateral total hip arthroplasty (THA). We investigated whether there was an excess of infection in such a group 7-10 years after total hip arthroplasty. A database of 49 patients who had undergone IASHI followed by ipsilateral THA was reviewed. The mean length of time between injecti...

We have undertaken a prospective, randomised study to compare conservation of acetabular bone after total hip replacement and resurfacing arthroplasty of the hip. We randomly assigned 210 hips to one of the two treatment groups. Uncemented, press-fit acetabular components were used for both. No significant difference was found in the mean diameter of acetabular implant inserted in the groups (5...

Pseudotumors associated with total hip arthroplasty have been associated with metal-on-metal and metal-on-polyethylene total hip arthroplasties due to a granulomatous foreign-body reaction to methyl methacrylate, polyethylene, or metal ion release, but they have not been related to prosthetic joint infections. In this paper, we report an unusual case of Candida albicans total hip arthroplasty i...

We compared joint proprioception in 12 hips in 12 patients with hemiarthroplasty after fracture of the hip, in 12 hips in 11 patients with total hip arthroplasty because of osteoarthritis and in a control group of 12 age-matched patients with no clinical complaints. There was no significant difference (p = 0.05) in joint proprioception in any of the groups. There was no decrease in joint propri...

PURPOSE The purpose of this study was to determine the extent of preoperative osteoarthritis (OA) that precludes benefit from hip arthroscopy by systematically reviewing the literature on hip arthroscopy in the setting of OA. METHODS We searched the Medline and PubMed databases using the following Medical Subject Heading terms: arthritis, osteoarthritis, chondral damage, chondral injury, chon...

Infection at the pseudoacetabulum in a patient with a high hip dislocation has not been reported previously in the English literature. We report a case of total hip arthroplasty in a 28-year-old female who presented to us with hip pain following debridement of the infected pseudojoint in a case of neglected developmental dysplasia of the hip. The infection was treated with thorough debridement ...

BACKGROUND Wear cannot be completely prevented after total hip arthroplasty. If severe polyethylene (PE) liner wear develops, the so-called catastrophic failure occurs and metallosis develops. We postulated that longevity of the new implant may be affected after revision surgery for metallosis following a catastrophic failure of a PE liner due to the substantial amount of PE wear particles and ...

BACKGROUND There is a lack of data on the long-term outcome of total hip arthroplasty procedures, as assessed by validated tools. METHODS We conducted a follow-up study to evaluate the quality of life and functionality of 250 patients an average of 16 years (range: 11-23 years) after total hip arthroplasty using a validated assessment set including the SF-36 questionnaire, Harris Hip Score, W...

The purpose of this study was to retrospectively evaluate the efficacy a tranexamic acid (TXA) perioperative protocol for primary hip- and knee arthroplasty, in terms allogenic blood transfusion rates. A retrospective cohort conducted included all hip arthroplasty procedures period 2014-2019. Patients who underwent surgery due trauma or revision were excluded. total amount 5205 patients eligibl...
