Sequential Bilateral Hip Fractures in Elderly Patients.

Purpose: To evaluate the incidence and presentation of osteoporotic sequential bilateral hip fractures (SBHF) in Center for Joint Disease, Chonnam National University Hwasun Hospital as there are limited studies with variable results reported in Korea.

Materials And Methods: Records of 507 patients aged >60 years old presenting with osteoporotic hip fractures between 2009 and 2015 were retrospectively reviewed to document the occurrence and presentation of sequential hip fractures; mean post-treatment follow-up was 48 months. Additionally, any correlations between sequential fractures and initial fracture and risk factors were assessed.

Survival and Risk Factor Analysis of Medial Open Wedge High Tibial Osteotomy for Unicompartment Knee Osteoarthritis.

Purpose: The purpose of this retrospective study was to evaluate the survival rates and analyze the factors that affect survival rate after primary treatment with medial open wedge high tibial osteotomy (MOWHTO) for medial unicompartmental knee osteoarthritis.

Methods: Clinical evaluation using Knee Society Score (KSS) and Western Ontario and McMaster Universities Osteoarthritis Index score and radiographic evaluation, including mechanical axis, were done before and after surgery. The main failure criteria for survival included the conversion to total knee arthroplasty or KSS of <60 points.

Shoulder Joint Infections with Negative Culture Results: Clinical Characteristics and Treatment Outcomes.

Background: The incidence of septic arthritis of the shoulder joint is increasing as the population ages. The prevalence of shoulder infection is also increasing because of the growing use of arthroscopy and expansion of procedures in the shoulder. However, cultures do not always identify all microorganisms, even in symptomatic patients.

Two-stage revision for periprosthetic joint infection of the hip: Culture-negative versus culture-positive infection.

Introduction: Negative culture findings are common in periprosthetic joint infection (PJI) of the hip.

Methods: Retrospective study was performed to total 84 patients which devided into two groups: culture-negative (n: 27) and culture-positive (n: 57).

Results: The reimplantation rate was 96.

Treatment outcome of dome osteotomy of the pelvis combined with trochanteric advancement for sequelae of Perthes' disease.

Objective: Disparity in size between femoral head and acetabulum could promote premature degeneration of the hip joint. The purpose of this study was to report the results of Kawamura's dome osteotomy for acetabular dysplasia due to sequelae of Perthes' disease.

Patients And Methods: Fourteen patients (14 hips) operated between 1999 and 2012 were retrospectively reviewed.

Breakage of the Tail Portion of the Lag Screw during Removal of Proximal Femoral Zimmer Natural Nail: Report of Two Cases with Technical Notes.
