How Do Changes in Femoral Anteversion Impact Femoral Rotation and Anterior Offset After Total Hip Arthroplasty?

Background: The impact of femoral anteversion changes on femoral rotation and anterior offset following total hip arthroplasty (THA) has not been well studied. This study therefore investigated the relationship among femoral anteversion, anterior offset, and femoral rotation before and after THA.

Methods: There were 995 patients who had staged primary bilateral THAs who received a preoperative supine computerized axial tomography (CT) scan, following a standardized protocol, for surgical planning prior to each THA.

The accuracy of restoration of femoral head centre of rotation in the anteroposterior plane after uncemented total hip arthroplasty : a CT-based study.

Aims: Hip arthroplasty aims to accurately recreate joint biomechanics. Considerable attention has been paid to vertical and horizontal offset, but femoral head centre in the anteroposterior (AP) plane has received little attention. This study investigates the accuracy of restoration of joint centre of rotation in the AP plane.

National Joint Registry recorded untoward intraoperative events during primary total hip arthroplasty: an investigation into the data accuracy, causal mechanisms and attributability.

Introduction: Untoward intraoperative events occurring during total hip arthroplasty are recorded by the National Joint Registry through Minimum Data Set (MDS) forms. This data may be used to assess the safety of implants. The aim of this study is to evaluate the accuracy of the untoward intraoperative events, assess the mechanism and ascertain whether these events were attributable to the implants inserted.

Management of neck of femur fracture in an adult with short stature and learning disability.

Neck of femur fractures (NOFF) are one of the major health concerns, with their incidence and the cost of care rising each year. Though a plethora of literature remains available on NOFF and its management, we found very little evidence for management of NOFF in patients with short stature and learning disability. Because of this unique combination of conditions in our patient, we had to deviate from the standard practice in terms of the implant choice.

Role of preoperative magnetic resonance imaging in patients with quiescent septic arthritis undergoing primary total hip arthroplasty.

Aim: to evaluate the role of preoperative magnetic resonance imaging (MRI) in assessing patients with a history of undergoing total hip arthroplasty.

Materials And Methods: retrospective consecutive study of patients with previous history of septic arthritis who underwent MRI scans of their hips prior to primary hip arthroplasty surgery and who also had minimum 2 years follow up postoperatively. Detailed radiographic examinations were obtained, demographic and microbiological data collected.
