Twelve consecutive dislocated hip prostheses and one dislocated hip joint were reduced in the emergency room using the method described in this paper. This method has multiple advantages. It uses a lever and fulcrum technique and therefore is capable of producing substantial levels of force with less effort. The patient and physician are in relatively comfortable positions and little assistance is necessary.

Objective: Spinopelvic sagittal balance ensures efficient posture and minimizes energy expenditure by aligning the spine, pelvis, and lower extremities. Deviations can cause clinical issues like back pain and functional limitations. Key radiographic parameters, including pelvic tilt (PT), pelvic incidence (PI), sacral slope (SS), and lumbar lordosis (LL), are essential for evaluating spinal pathologies and planning surgeries.

Background: Hip instability following total hip arthroplasty (THA) is among the most common indications for revision surgery. The implantation of dual-mobility (DM) systems, designed to improve stability, continues to rise, and thus, characterizing in vivo implant damage modes is paramount.
Methods: Under an implant retrieval protocol, 51 DM THA systems were analyzed.

Background: Periprosthetic hip dislocation after total hip arthroplasty is a devastating postoperative complication. It is often associated with suboptimal orientation of the acetabular component, characterized by the acetabular abduction and anteversion angles obtained from anteroposterior pelvic radiographs. We introduce a novel automated web tool to streamline the subjective and lengthy process of this manual measurement and compare it to manual human measurements.

It was hypothesized that the stem size planned with accordance to the diaphyseal canal width alone can accommodate the distal femur successfully with no sizing mismatch. Forty-six patients (53 hips) suffering from secondary osteoarthritis due to hip dysplasia scheduled for total hip arthroplasty (THA) with a subtrochanteric transverse shortening osteotomy were included.
View Article and Find Full Text PDFDislocation is the second most common indication for revision total hip arthroplasty (THA). In revision cases the dislocation rate can be as high as 5-30%. The aim of this study was to assess the outcome, specifically the dislocation rate in revision THA where a dual mobility cup was used.
