Staged Fixation with Respect to Soft Tissue in Tibial Plateau Fractures with Acute Compartment Syndrome: Correlation Analysis of Complications.

Backgroud: Staged operations are commonly employed in the management of high-energy tibial plateau fractures (TPF) complicated by acute compartment syndrome (ACS); however, complications, such as nonunion, deep wound infection, and traumatic arthritis, often occur due to severe bone and soft-tissue damage. We aimed to report the radiological and clinical outcomes of staged surgical interventions performed following complete closure of the fasciotomy wound for the treatment of TPF complicated by ACS. Additionally, we analyzed factors associated with complications arising from these procedures.

Identification of risk factors and clinical outcomes for symmetric peripheral gangrene: A new scoring system using a common data model database.

Symmetrical peripheral gangrene (SPG) is a destructive clinical condition where amputation is often the final treatment option. We aimed to identify the predictors of SPG using the common data model (CDM) and propose a new scoring system for predicting hospitalized patients at risk of developing SPG. A cohort of patients treated with intravenous noradrenaline, epinephrine, and vasopressin between 2011 and 2020 was retrospectively analyzed using the CDM database.

This study aimed to report the clinical application of the RSAF flap and to evaluate its reliability in older adult patients.

Cbfβ Is a Novel Modulator against Osteoarthritis by Maintaining Articular Cartilage Homeostasis through TGF-β Signaling.

TGF-β signaling is a vital regulator for maintaining articular cartilage homeostasis. Runx transcription factors, downstream targets of TGF-β signaling, have been studied in the context of osteoarthritis (OA). Although Runx partner core binding factor β (Cbfβ) is known to play a pivotal role in chondrocyte and osteoblast differentiation, the role of Cbfβ in maintaining articular cartilage integrity remains obscure.

The purpose of this study was to report mid-term to long-term reconstruction results for thumb (radial) polydactyly.

Staged Management of Severely Displaced Calcaneal Fractures With Transarticular Pinning: A Damage Control Strategy.

Background: Severely displaced calcaneal fractures can result in considerable morphology derangement and may be accompanied by soft tissue compromise. Delayed operative restoration of the calcaneal morphology may result in acute retensioning of the damaged soft tissue with associated wound-related complications. In this study, we describe a staged treatment of displaced intra-articular calcaneal fractures that uses temporary transarticular Kirschner wire (K-wire) fixation and staged conversion to definite fixation.

Open-wedge high tibial osteotomy in patients with discoid lateral meniscus.

Background: There are concerns about the progression of the lateral osteoarthritis (OA) should be taken into account when high tibial osteotomy (HTO) is performed in patients with discoid lateral meniscus (LM). This study evaluated the clinical results of HTO in patients with discoid LM and elucidated factors affecting the results.

Methods: This study evaluated 32 female patients with varus deformity and medial OA.

The patellofemoral joint does not deteriorate clinically after open-wedge high tibial osteotomy.

Background: After high tibial osteotomy (HTO), the loading of the lateral compartment can be increased. Moreover, the change of patellar height may adversely affect the patellofemoral joint and functional outcomes.

Hypothesis: We hypothesized that the cartilage of the lateral compartment and patellofemoral joint would worsen after open-wedge HTO and the overcorrection of HTO could worsen the cartilage state of the patellofemoral joint.

Excellent outcomes after double-locked plating in very low periprosthetic distal femoral fractures.

Introduction: Very low periprosthetic distal femur fractures (PPDFFs) are rare injuries and often have a relatively high failure rate after single lateral locked plating. The double plating technique yields good outcomes in osteoporotic fractures of the distal femur. To date, there is limited information on double-locked plate fixation of very low PPDFFs.

Can medial stability be preserved after open wedge high tibial osteotomy?

Purpose: This study evaluated the medial joint stability after high tibial osteotomy (HTO) releasing the superficial medial collateral ligament (sMCL) without cutting and repairing.

Methods: Twenty-one patients who performed HTO were enrolled. After an L-shaped incision was made in the pes anserinus, the sMCL was released from the distal portion during surgery.
