Imaging evaluation of extraarticular posterior loose bodies in varus ankle osteoarthritis.

Multiple loose bodies (LBs) are often found in patients with varus ankle osteoarthritis (OA). This study aimed to investigate the characteristics of extra-articular posterior ankle LBs in patients with varus ankle OA. We also sought to determine whether there were variations in the characteristics of LBs according to the degree of ankle OA.

Outcome comparison of minimally invasive proximal and distal chevron Akin osteotomies in patients with severe hallux valgus deformity: A randomized prospective study.

Purpose: To date, the surgical treatment of severe hallux valgus deformity remains challenging despite the various methods presented. This study aimed to compare the effectiveness of minimally invasive distal chevron Akin osteotomies (d-MICA) and minimally invasive proximal chevron Akin osteotomies (p-MICA) in correcting severe hallux valgus deformities.

Methods: This prospective follow-up study included patients randomly assigned to undergo p-MICA or d-MICA for hallux valgus deformities with a preoperative hallux valgus angle (HVA) ≥ 40° and/or a first to second intermetatarsal angle (IMA) ≥ 16°.

A comparison of characteristics and outcomes of operative treatment for Achilles tendon sleeve avulsion in older versus younger patients.

Introduction: Achilles tendon sleeve avulsion (ATSA) is a rare injury that often results from pre-existing insertional Achilles tendinopathy and occurs when a tendon avulses from the insertion as a continuous sleeve. To date, outcomes of operative treatment for ATSA in older patients have not been reported. Therefore, this study aims to compare the characteristics and outcomes of Achilles tendon (AT) reattachment with or without tendon lengthening for ATSA between older and younger patients.

Radiographic Outcomes of Proximal vs Distal Syndesmotic Low Tibial Osteotomy.

Background: We aimed to determine whether the location of tibial osteotomy affects the outcome during low tibial osteotomy (LTO) with fibular osteotomy for varus ankle arthritis by comparing proximal syndesmotic (PS) and distal syndesmotic (DS) tibial osteotomy.

Methods: We retrospectively reviewed the radiographic findings of 50 cases (among 47 patients) who underwent LTO with fibular osteotomy for varus ankle arthritis. The enrolled patients were divided into 2 groups according to the location of the tibial osteotomy: the PS group (25 cases, 24 patients) and the DS group (25 cases, 23 patients).

Eflapegrastim's enhancement of efficacy compared with pegfilgrastim in neutropenic rats supports potential for same-day dosing.

Eflapegrastim (Rolontis) is a long-acting granulocyte colony-stimulating factor (G-CSF) with an IgG4 Fc fragment and short polyethylene glycol linker. Current G-CSF products are administered 24 hours after chemotherapy. The present study compares the duration of neutropenia (DN) with eflapegrastim or pegfilgrastim at 0, 2, 5, or 24 hours post chemotherapy.

Factors affecting unused remaining volume of intravenous patient-controlled analgesia in patients following laparoscopic gynecologic surgery.

Purpose: This study was undertaken to evaluate the factors affecting the unused remaining volume of intravenous patient-controlled analgesia (IV PCA) in patients who had undergone laparoscopic gynecologic surgery.

Methods: We retrospectively collected patient records from pre-existing PCA log sheets from 98 patients. Surgical factors and IV PCA-related data including remaining volume, administration duration, early discontinuation (yes or no), and adverse reactions were recorded.
