To explore how the thickness of the femoral lateral wall influences the effectiveness of internal fixation systems used to treat intertrochanteric fractures. CT images of the pelvis and femur of a male adult were used to construct an intertrochanteric fracture model (AO/OTA 31-A2) with various thicknesses of the femoral lateral wall (FLW). Four finite element (FE) models were created with the lateral femoral walls being 10 mm, 20 mm, 30 mm, and 40 mm thick.

Background: Recent progress in the chemotherapy and surgical procedures for osteosarcoma have enabled the preservation of limb function even when cancer occurs in the distal radius, a rare primary site of osteosarcoma.
Case Report: We describe a case of osteosarcoma that occurred in an 18-year-old, male Kyudo (Japanese archery) archer's left distal radius. Since the patient desired to resume Kyudo and the left hand was quite important for gripping a bow, we chose partial wrist arthrodesis (fibulo-scapho-lunate arthrodesis) with free vascularized fibular grafting (FVFG) as the reconstruction procedure following wide resection.

The Zavanelli manoeuvre is often the final resort of the clinician facing undeliverable shoulder dystocia and we present retrospective pooled data comprising 110 shoulder dystocia cases, 11 impacted breech and 11 locked twin deliveries assessed from ten case series and 38 individual case reports. Although recommended when other external and internal manipulations have failed, we suspect that many clinicians have not had formal training on how to conduct the manoeuvre and may be unfamiliar with the steps involved, leading to a reluctance and delay in initiating this. We describe original descriptions of the manoeuvre, examine its use in intractable shoulder dystocia and illustrate stepwise the cephalic replacement technique.

Unilateral cochlear implantation (CI) limits deafness-related changes in the auditory pathways but promotes abnormal cortical preference for the stimulated ear and leaves the opposite ear with little protection from auditory deprivation. In the present study, time-frequency analyses of event-related potentials elicited from stimuli presented to each ear were used to determine effects of unilateral CI use on cortical synchrony. CI-elicited activity in 34 adolescents (15.

Background: Intramedullary nails have become the main treatment for intertrochanteric fractures. However, a distal locking procedure during nailing gradually raised controversy. In this study, a systematic review and meta-analysis of clinical trials was performed to summarize existing evidence, aiming to determine the safety and efficacy of distal locking or unlocking in the nailing of stable intertrochanteric fractures.
