Effects of lateral circumflex femoral artery ligation on blood flow to the surrounding muscles in the direct anterior approach.

Background: The direct anterior approach to the hip joint enables the identification and ligation of the lateral circumflex femoral artery. However, the effect of lateral circumflex femoral artery ligation on blood flow to the muscles surrounding the hip remains unknown. This study clarified the changes in blood flow to the surrounding muscles following ascending branch ligation of this artery.

The Utility of False-Profile Radiographs for the Detection of Osteoarthritis Progression in Acetabular Dysplasia.

Background: Both the lateral center-edge angle and acetabular roof obliquity on anteroposterior radiographs are well-known prognostic predictors of osteoarthritis progression in patients with acetabular dysplasia. However, few studies have evaluated osteoarthritis progression on false-profile radiographs. In the present study, osteoarthritis progression was evaluated on anteroposterior and false-profile radiographs.

The prevalence and risk factors for delayed union of the superior pubic ramus at one year after curved periacetabular osteotomy: its risk factor and outcome.

Purpose: Curved periacetabular osteotomy (CPO) has been developed for the treatment of acetabular dysplasia. While several studies have reported its good clinical results, the complications of CPO include delayed union and nonunion of the superior pubic ramus. The purpose of this study is to investigate the prevalence of delayed union of the pubis one year after CPO, and to determine the risk factors for this complication.

Incidence of delayed union one year after peri-acetabular osteotomy based on computed tomography.

Background: Pubic bone nonunion and delayed union are reported as post-operative complications after peri-acetabular osteotomy (PAO). However, few studies have determined the incidence of delayed union using computed tomography (CT) scans. This study aimed to determine the incidence of delayed union at one year after PAO using X-ray and CT scans.

Open pelvic ring fracture and multiple fractures of the lower extremities: a case report.

A 73-year-old female was hit by a car, and transferred to our hospital. On examination, her consciousness was alert, but her vital signs were unstable. There are three 10-cm open wounds on her right buttock.
