INTRODUCTION The anatomy of the proximal femur at the time of total hip arthroplasty has been widely studied but the horizontal plane was never considered, or only limited to the torsion of the femoral neck. METHODS Using CT-scan images from a group of 178 patients scheduled for cementless total hip arthroplasty (THA), we analysed the evolution of the torsion of the proximal femoral metaphysis, in reference to the posterior bicondylar plane of the femur. The evolution of the torsion, between 20 ...

INTRODUCTION There is conflicting evidence as to whether or not patients undergoing total hip arthroplasty (THA) via the direct anterior approach (DAA) have increased risk of component malposition. The aim of this study was to investigate whether specific preoperative radiographic features were predictive of postoperative component malposition in DAA THA. PATIENTS AND METHODS We examined 204 THA operations performed for osteoarthritis via the DAA at a single institution. Preoperative radiographs...

BACKGROUND Bony morphology is central to the pathomechanism of femoroacetabular impingement syndrome (FAIS), however isolated radiographic measures poorly predict symptom onset and severity. More comprehensive morphology measurement considered together with patient factors may better predict symptom presentation. This study aimed to determine the morphological parameter(s) and patient factor(s) associated with symptom age of onset and severity in FAIS. METHODS 99 participants (age 32.9 ± 10.5 ye...

INTRODUCTION Third-generation hemispheric, titanium porous-coated (HTPC) acetabular cups have been shown to achieve good biologic fixation through enhanced porous ingrowth surfaces. They also allow for a wide range of bearing options, including polyethylene, dual-mobility, and ceramic liners. The purpose of the study is to review the mid-term clinical outcomes an HTPC acetabular cup with a minimum of 7-year follow-up. METHODS A retrospective, observational study was conducted on all consecutive ...

Background:The combined anteversion theory to prevent impingement in total hip arthroplasty (THA) has been proposed. However, because stem-anteversion is influenced by the native femoral anteversio...

AIM The purpose of this study was to use computational modeling to determine if surgical correction of hip dysplasia restores hip contact mechanics to those of asymptomatic, radiographically normal hips. METHODS Discrete element analysis (DEA) was used to compute joint contact stresses during the stance phase of normal walking gait for 10 individuals with radiographically normal, asymptomatic hips and 10 age- and weight-matched patients with acetabular dysplasia who underwent periacetabular oste...

PURPOSE To define the anatomical relationship of the major neurovascular structures to the standard endoscopic portals used in endoscopic hamstring repair. A secondary outcome was to determine the safest angle of insertion from each standard portal. METHODS Endoscopic portals were established in the 3 standard locations (lateral, medial, and inferior) and Steinmann pins inserted at various angles. Each hip was dissected and the distance between the pins and the pertinent anatomy measured. RESULT...

OBJECTIVES This study sought to delineate the postoperative outcomes in dialysis patients undergoing hip hemiarthroplasty (HHA) for the treatment of femoral neck fractures (FNF) in order to better optimise pre- and postoperative management and minimise short-term morbidity and mortality rates. METHODS 16,955 patients who had undergone HHA for femoral neck fractures from 2005 to 2018 were isolated from a multi-institutional surgical registry, of which 343 (2.0%) were on dialysis and 16,612 (98.0%...

PURPOSE Femoral neck fractures in young patients are associated with increase complication risk. The objective of this study was to evaluate the results of quadratus femoris muscle pedicle grafting in the treatment of ununited femoral neck fractures. METHODS This study includes 16 patients with ununited femoral neck fractures treated with quadratus femoris muscle pedicle graft. 7 patients had neglected femoral neck fractures while 9 had ununited femoral neck fractures after fixation. Quadratus f...

Purpose:Aseptic loosening is rare after primary total hip arthroplasty (THA) with mostly uncemented tapered stems; however, different factors can modify the results. We question whether 3 different...
