Long-term course of developmental dysplasia of the hip: follow-up of the non-operated hips of patients undergoing unilateral rotational acetabular osteotomy for twenty-four years.

Purpose: To follow-up the non-operated hips of patients who underwent unilateral rotational acetabular osteotomy (RAO) for bilateral developmental dysplasia of the hip (DDH) for a minimum of 20 years to clarify (1) the timing of onset of hip osteoarthritis (OA) in DDH, and (2) factors associated with the development of OA.

Methods: This study included 92 non-operated hips of patients who underwent unilateral RAO for bilateral DDH. We examined the timing of OA onset and total hip arthroplasty (THA) and the joint survival rate in the studied hips.

Arthroscopic Treatment of a Ganglion Cyst Originating from the Transverse Acetabular Ligament in the Hip Joint A Case Report.

Introduction: Intra-articular ganglion in the hip joint is rare. Here, we present a case of ganglion cyst originating from the transverse acetabular ligament (TAL) in the hip joint treated by arthroscopic surgery.

Case Report: A 48-year-old man presented with the right groin pain after activity.

Do radiological findings around the Fitmore stem change over time? : radiolucency around the short hip stem disappears within a few years: a retrospective study.

Aims: Although the short stem concept in hip arthroplasty procedure shows acceptable clinical performance, we sometimes get unexplainable radiological findings. The aim of this retrospective study was to evaluate changes of radiological findings up to three years postoperatively, and to assess any potential contributing factors on such radiological change in a Japanese population.

Methods: This is a retrospective radiological study conducted in Japan.

What is the most cost-effective strategy for nasal screening and Staphylococcus aureus decolonization in patients undergoing total hip arthroplasty?

Background: To reduce periprosthetic joint infection after total hip arthroplasty (THA), several nasal screening and decolonization strategies for methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) have been performed. These include universal decolonization (UD; i.e.

Can sterility of stripped iodophor-impregnated plastic adhesive drape be maintained at the time of incision closure in total hip arthroplasty?

Objective: The aim of this study was to analyze the contamination rates of the skin under the iodophor-impregnated plastic adhesive drape (IOD) at the time of incision closure in total hip arthroplasty (THA).

Methods: A total of 225 patients undergoing primary THA (28 men, 197 women; mean age=65 years; age range=30-85) were included in this study. After asepsis using a solution of 1% chlorhexidine with 83% alcohol by volume, the surgical site was painted with a 10% povidone-iodine solution, and IOD was attached tautly at the start of surgery.

Postoperative creatine kinase elevation following hip arthroscopy and associated risk factors.

Objective: The aim of this study was to investigate postoperative CK and risk factors for CK elevation after hip arthroscopy.

Methods: This retrospective study reviewed 122 patients (50 males, 72 females; mean age, 44.1 years) who underwent hip arthroscopy from September 2012 to March 2018.
