Aims: The aim of this randomized trial was to compare the functional outcome of two different surgical approaches to the hip in patients with a femoral neck fracture treated with a hemiarthroplasty.
Patients And Methods: A total of 150 patients who were treated between February 2014 and July 2017 were included. Patients were allocated to undergo hemiarthroplasty using either an anterolateral or a direct lateral approach, and were followed for 12 months. The mean age of the patients was 81 years (69 to 90), and 109 were women (73%). Functional outcome measures, assessed by a physiotherapist blinded to allocation, and patient-reported outcome measures (PROMs) were collected postoperatively at three and 12 months.
Results: A total of 11 patients in the direct lateral group had a positive Trendelenburg test at one year compared with one patient in the anterolateral group (11/55 (20%) 1/55 (1.8%), relative risk (RR) 11.1; p = 0.004). Patients with a positive Trendelenburg test reported significantly worse Hip Disability Osteoarthritis Outcome Scores (HOOS) compared with patients with a negative Trendelenburg test. Further outcome measures showed few statistically significant differences between the groups.
Conclusion: The direct lateral approach in patients with a femoral neck fracture appears to be associated with more positive Trendelenburg tests than the anterolateral approach, indicating a poor clinical outcome. Cite this article: 2019;101-B:793-799.

Background: The aim of our study is to compare the effect of the 30° reverse Trendelenburg position combined with the beach chair position on respiratory parameters in laparoscopic sleeve gastrectomy (LSG) with the 30° reverse Trendelenburg position alone.
Material And Method: Fifty patients with body mass index > 30 were included in the study. The patients were divided into two groups; in the control group, the standard 30° reverse Trendelenburg.

The gluteus medius allows hip abduction and stabilization of the pelvis when walking. A rupture of the gluteus medius tendon is associated with lateral hip pain, weakness, a positive Trendelenburg sign, and a limp. Diagnosis is confirmed by ultrasound or MRI.

The superior gluteal nerve (SGN) is a mixed nerve of the sacral plexus that arises from the posterior divisions of the L4, L5, and S1 nerve roots. Its motor branch plays a crucial role in innervation of hip muscles, which allows for physiological gait or walk-pattern. As for its sensory branch, it provides innervation for the hip joint capsule, especially its superior part.

Article Synopsis
- - The study evaluated the use of Paavilainen osteotomy in combination with total hip arthroplasty (THA) for treating high developmental hip dislocation, focusing on effectiveness and risk factors for nonunion after the procedure.
- - A total of 44 patients were reviewed over an average follow-up of 4.4 years, showing significant improvement in hip function scores, with a 12% incidence of nonunion, which was linked to the length of contact between the osteotomy block and femoral cortex.
- - The research concluded that this combined surgical approach is effective and less complex than other methods for high-dislocation hip dysplasia, with a critical contact length of 2.15 cm identified as essential for
Trendelenburg gait after total hip arthroplasty due to reduced muscle contraction of the hip abductors and extensors.

Article Synopsis
- Some patients who undergo total hip arthroplasty (THA) for hip osteoarthritis may still exhibit a Trendelenburg gait, which involves a specific pattern of muscle contractions during walking.
- The study analyzed 89 patients with a focus on hip muscle performance and pelvis movement to identify factors contributing to this gait, finding that 27% displayed the Trendelenburg gait.
- Key findings suggest that poor performance in hip abductor and extensor muscles during early to mid-stance phases of walking is linked to difficulty in stabilizing the hip, highlighting the importance of these muscle functions after surgery.
