Although highly positive results for wear reduction of cross-linked polyethylene (HXLPE) have been reported around the 10-year follow-up, long-term result related to reoperation and wear-related survival is still an issue. Therefore, this study aimed compare follow-up a single manufacture's liner >15 years in terms rate.This retrospective cohort included 134 primary total hip arthroplasties (THAs) who were followed up at least 15 years. The mean age time surgery was 50.7 (conventional [CPE]...

Abstract One of the key aspects diagnosis and treatment atypical femoral fractures is early detection incomplete prevention their progression to complete fractures. However, an fracture can be misdiagnosed as a normal lesion by both primary care physicians orthopedic surgeons; expert consultation needed for accurate diagnosis. To overcome this limitation, we developed transfer learning-based ensemble model detect localize A total 1050 radiographs, including 100 fractures, were preprocessed...

Abstract This study aimed to evaluate the early results of primary total hip arthroplasty (THA) using dual mobility (DM) cups in patients at a risk dislocation and compare them with that fixed bearing (FB) THA. retrospective included who had undergone THA between January 2016 December 2018 were dislocation. A propensity score-matched analysis was conducted for 63 procedures vitamin-E infused highly cross-linked polyethylene (VEPE) DM performed FB from same manufacturer mean follow-up period...

Abstract Total hip replacement arthroplasty (THA) in dysplasia patients has a higher dislocation rate than with simple osteoarthritis due to anatomical deformation. Therefore, reduce postoperative THA is the challenge for surgeons. From 2015 2020, 1525 underwent performed by two surgeons at single institution. A total of 152 involving 172 THAs were included. The classified into dual-mobility (DM) and fixed-bearing (FB) acetabular cup groups. occurrence functional evaluation joint, was...

Isolated greater trochanter (GT) fractures are relatively rare and few studies have assessed the appropriate diagnostic therapeutic strategies for these fractures. When initial plain radiographs show an isolated GT fracture, underestimation of occult intertrochanteric extension may result in displacement a previously non-displaced fracture. This study examined clinical results value different elderly patients with on radiographs.Between January 2010 2015, 30 showing were using MRI, bone...

Purpose:We evaluated the geometric discrepancies between proximal femur in Koreans and two types of femoral nail using plain radiographs.Materials Methods: A total 100 consecutive patients (38 treated with antirotation [PFNA], 62 PFNA II) intertrochanteric fracture were retrospectively identified.The minimum follow up period was 32 months.The analysis performed preoperative true hip antero-posterior radiographs unaffected side, data compared II dimensions.Postoperative assessments...

Abstract Background Transverse acetabular fractures, although classified as elementary, have worse outcomes than other types of fractures. Prognostic factors for this fracture type are not clearly established. This study aimed to assess the surgical transverse fractures and subtypes thereof investigate prognostic factors. Methods Between 2014 2019, 39 patients (39 hips) had or thereof. We reviewed evaluated patient factors, injury in relation osteoarthritis (OA) conversion total hip...

Purpose: This study aimed to evaluate the surgical outcomes of biologic plating using locking compression plate-distal femur (LCP-DF) in patients with subtrochanteric fracture femur.Materials and Methods: Between January 2010 December 2013, 28 consecutive fractures femur, treated fixation LCP-DF, were enrolled.Preoperative values, including patient age, sex, body mass index, type, type lung injury, timing from injury surgery, retrospectively evaluated.Radiologic assessments included time...

We analyzed the surgical outcomes at two institutions after internal fixation using multiple screws in femoral neck fractures with valgus impaction to determine independent predictors and their cut-off values for nonunion reoperation.Between January 2006 December 2016, 104 that underwent from were enrolled. The logistic regression model receiver operating characteristics analysis used reoperation.There 20 reoperations (19.2%) due 11 nonunions (10.6%) nine cases of head osteonecrosis (8.7%)....
