Does Sacral Slanting Affect Postoperative Shoulder Balance in Patients With Lenke Type 2A Adolescent Idiopathic Scoliosis?

Objective: Even minor sacral slanting can influence T1 tilt and shoulder balance. Yet, the relationship between sacral slanting and postoperative shoulder imbalance (PSI) has not been previously explored. To determine risk factors for PSI in Lenke 2A adolescent idiopathic scoliosis (AIS) patients, with an emphasis on sacral slanting.

Efficacy and safety of oblique posterior endplate resection for wider decompression (trumpet-shaped decompression) during anterior cervical discectomy and fusion.

Objective: Anterior cervical discectomy and fusion (ACDF) provides a limited workspace, and surgeons often need to access the posterior aspect of the vertebral body to achieve sufficient decompression. Oblique resection of the posterior endplate (trumpet-shaped decompression [TSD]) widens the workspace, enabling removal of lesions behind the vertebral body. This study was conducted to evaluate the efficacy and safety of oblique posterior endplate resection for wider decompression.

Enhancement of Steel Sandwich Sheet Adhesion Using Mechanical Interlocking Structures Formed by Electrochemical Etching.

Steel sandwich sheets (steel-polymer-steel), which are composed of lightweight polymers bonded on both sides with rigid steel sheets, have recently been developed as functional lightweight materials. In this study, a steel sandwich sheet (electrogalvanized (EG) steel sheet-polypropylene (PP)-EG steel sheet) with improved normal adhesion is fabricated without adhesives. Instead, adhesion is achieved via mechanical interlocking between the etched EG steel sheets and PP.

Feasibility of CaO-SiO-PO-BO Bioactive Glass Ceramic Cage in Anterior Cervical Diskectomy and Fusion.

Background: CaO-SiO-PO-BO bioactive glass ceramic (BGC) is known to chemically bond with bones by forming a hydroxyapatite layer and inducing osteoblastic differentiation. This study was conducted to compare the clinical outcomes, radiographic outcomes, and safety of a CaO-SiO-PO-BO BGC cage in anterior cervical diskectomy and fusion (ACDF) with those of an allograft interbody spacer.

Methods: A total of 63 patients who underwent 2-level ACDF to treat degenerative cervical radiculopathy/myelopathy were reviewed.

Effect of Lower-Extremity Angular Imbalance on Foot and Ankle Pain in Patients With Genu Varus Deformity.

When there is a varus knee deformity, the ankle and foot compensate. However, the association between pain and angular change in the compensatory mechanism is not well understood. Therefore, we investigated the relationship between pain and angular change of the lower extremity in genu varus patients.

How Does Ossification of Posterior Longitudinal Ligament Progress in Conservatively Managed Patients?

Study Design: Retrospective cohort study.

Objective: The aim of this study was to elucidate the progression of ossification of the posterior longitudinal ligament (OPLL) in conservatively managed patients and determine its risk factors SUMMARY OF BACKGROUND DATA.: Although several studies have demonstrated how OPLL progresses after laminoplasty or fusion, its progression in conservatively managed patients remains unclear.

Comparison of Revision Rates Due to Aseptic Loosening between High-Flex and Conventional Knee Prostheses.

Purpose: The purpose was to evaluate and compare the revision rate due to aseptic loosening between a high-flex prosthesis and a conventional prosthesis.

Materials And Methods: Two thousand seventy-eight knees (1,377 patients) with at least 2 years of follow-up after total knee arthroplasty were reviewed. Two types of implants were selected (LPS-Flex and LPS, Zimmer) to compare revision and survival rates and sites of loosened prosthesis component.

Effects of salmon DNA fraction and in a monosodium iodoacetate-induced osteoarthritis rat model.

PRF001 is a fragmented DNA polymer extracted from the testes of salmon. The purpose of this study was to assess the anti-inflammatory effect of PRF001 as well as the protective effect of PRF001 intake against arthritis in a rat model. , cell survival and inflammatory markers after HO treatment to induce cell damage were investigated in CHON-001 cells treated with different concentrations of PRF001.

Conservative Management after Intraoperative Over-Release of the Medial Collateral Ligament from its Tibial Insertion Site in Patients Undergoing Total Knee Arthroplasty.

During varus deformity correction in a patient undergoing total knee arthroplasty (TKA), the medial collateral ligament (MCL) could get completely detached from its distal insertion site. Our aim was to evaluate the (1) mid-term clinical outcome and implant survival after conservative treatment in patients with intraoperatively over-released MCL and (2) preoperative risk factors for MCL over-release. A retrospective study was conducted on patients who had undergone a primary TKA between 2001 and 2006.

Nonweightbearing Radiographs in Patients With a Subtle Lisfranc Injury.

Background: A midfoot sprain can be easily missed because of minimal findings on initial radiographs, which are almost universally nonweightbearing. We investigated preoperative nonweightbearing plain radiographic images in patients who were found to have unstable subtle Lisfranc injuries.

Methods: We retrospectively reviewed 51 patients who were operated on between February 2004 and March 2015.
