Efficacy of various core decompression techniques versus non-operative treatment for osteonecrosis of the femoral head: a systemic review and network meta-analysis of randomized controlled trials.

Background: Various Joint-preserving therapy (JPT) methods have been performed and tried in recent decades, but their results and efficacy were inconsistent and controversial. The purpose of this study is to evaluate its effectiveness and whether there are statistical differences in treatment between different interventions based on published RCT studies.

Methods: Following the PRISMA-NMA checklist, Medline, EMBASE, Web of Science, and Cochrane Library databases were searched and collected related RCT studies.

Madelung Disease Epidemiology and Clinical Characteristics: a Systemic Review.

Background: Madelung disease is a rare lipid metabolic disorder, and most cases are sporadically reported. There are currently no systematic reviews summarizing the epidemiological and clinical characteristics of this disease. The purpose of the current article is to extract and analyze the existing evidence concerning Madelung disease derived from case series in order to provide adequate treatments for patients based on a more comprehensive understanding of the disease.

Treatment of volar defects of the finger using dorsal digital-metacarpal flap versus free medial plantar artery flap: a comparative study.

Background: The treatment of defects on the volar surface of the finger has been scarcely reported, and its utility for digital resurfacing remains unclear. This study compared the outcomes of free medial plantar artery flap (MPAF) and dorsal digital-metacarpal flap (DDMF) in finger reconstruction.

Methods: This retrospective cohort study included 24 patients with soft-tissue defects on the volar surface of the finger from March 2014 to March 2017.

Differences between simple trapeziectomy and trapeziectomy with ligament reconstruction and tendon interposition for the treatment of trapeziometacarpal osteoarthritis: a systematic review and meta-analysis.

Background: The optimal management of trapeziometacarpal osteoarthritis remains controversial. This systematic review and meta-analysis assessed the subjective and objective outcomes and complications of simple trapeziectomy (T) versus trapeziectomy with ligament reconstruction and tendon interposition (T + LRTI).

Methods: The PubMed, Embase, Web of science, and Cochrane electronic databases were searched from inception to Aug 31, 2020.

Femoral nerve compression caused by a hibernoma in the right thigh: a case report and literature review.

Background: A hibernoma, also known as a brown fat tumor, is a rare benign soft tissue tumor, which originates from brown adipose tissue remaining in the fetus after the gestational period. It is often detected in adult men, presenting as a painless slow-growing mass. Hibernomas of the thigh have been reported; however, motor and sensory disorders caused by the tumors compressing the femoral nerve have not been reported.
