Hand flexor tendon injuries are common and biomechanically challenging to achieve good functional outcomes. Several approaches using the Pennington-modified Kessler repair technique have been attempted, but high-level evidence is still lacking. Here, we evaluated the relative efficacy of 3 versions of the Pennington-modified Kessler technique in repairing complete flexor digitorum profundus (FDP) laceration in Zone 1. We conducted a two-year, single-centre, double-blind, randomized clinical trial involving 85 patients with 105 digits enrolled between June 1, 2017, and January 1, 2019...

Bone cement is often used in the surgical treatment of Ewing sarcoma (ES). Chemotherapy-impregnated cement (CIC) has never been tested in slowing ES growth. The purpose of the study is to determine if CIC can decrease cell proliferation, and to assess changes in the mechanical qualities of the cement. Chemotherapeutic agents including doxorubicin, cisplatin, etoposide, and SF2523 were mixed with bone cement. ES cells were plated and exposed to cell growth media that had contained CIC or regular bone cement (RBC) as a control, and cell proliferation assays were performed daily for three days...

While recent studies showed that macrophages are critical for bone fracture healing, and lack of M2 macrophages have been implicated in models of delayed union, functional roles for specific M2 receptors have yet to be defined. Moreover, the M2 scavenger receptor CD163 has been identified as a target to inhibit sepsis following implant associated osteomyelitis, but potential adverse effects on bone healing during blockage therapy have yet to be explored. Thus, we investigated fracture healing in C57BL/6 vs...

Patellar tendons are assumed to be uniform in morphology and mechanical properties despite a higher prevalence of tendinopathies observed in the medial region. The purpose of this study was to compare the thickness, length, viscosity, and shear modulus of the medial, central, and lateral regions of healthy patellar tendons of young males and females in vivo. B-mode ultrasound and continuous shear wave elastography were performed on 35 patellar tendons (17 females, 18 males) over three regions of interest. A linear mixed-effects model (α = 0...

Tendons and ligaments have a poor innate healing capacity, yet account for 50% of musculoskeletal injuries in the US. Full structure and function restoration post-injury remains an unmet clinical need. This study aimed to assess the application of novel 3D printed scaffolds and induced pluripotent stem cell-derived mesenchymal stem cells (iMSCs) overexpressing the transcription factor Scleraxis (SCX, iMSCSCX+ ) as a new strategy for tendon defect repair. The polycaprolactone (PCL) scaffolds were fabricated by extrusion through a patterned nozzle or conventional round nozzle...

The rat mono-iodoacetate arthritis model has been used in studies on the hip, knee, and ankle joints. Few studies have explored its utility in shoulder arthritis research, and none have evaluated the effects of time and different mono-iodoacetate doses on arthritis progression. Therefore, we developed a rat mono-iodoacetate shoulder arthritis model to evaluate articular changes through radiological and histological analyses. Sprague-Dawley rats (n=108) were equally divided into groups that were intra-articularly injected with 0...

Femoral version (FV) deformities are common in patients with developmental dysplasia of the hip (DDH) and may contribute to cartilage damage due to abnormal joint loading. Derotational femoral osteotomy (DFO) surgery corrects FV deformities. However there is little consensus about the femoral transection location for DFO, and its influence on joint loads is unknown. The purpose of this study was to compare the effects of two common DFO locations on muscle forces and hip joint reaction forces (JRFs) in patients with DDH...

Osteoarthritis (OA) contributes to significant medical and socioeconomic burden in many populations. Its prevalence is expected to rise continuously owing to the combined effects of aging and increase in risk factors, including obesity, physical inactivity, and joint injuries. Pain is a hallmark presentation of OA. Topical nonsteroidal anti-inflammatory drugs (NSAIDs) are recommended by many international guidelines as an early treatment option of the management of osteoarthritic pain. However, the use of topical NSAIDs remains low in Malaysia and appears not to be a preferred agent in managing OA pain by prescribers...

Composite tissue injuries (CTIs) in extremities include segmental bone defects (SBDs) and volumetric muscle loss. The objective of this study was to determine if skeletal muscle autografting with minced muscle grafts (MMGs) could improve healing in a SBD and improve muscle function in a porcine CTI model that includes a SBD and adjacent volumetric muscle loss injury. Adult Yucatan Minipigs were stratified into three groups including specimens with an isolated SBD, an SBD with volumetric muscle loss (CTI), and an SBD with volumetric muscle loss treated with MMG (CTI+MMG)...

The Levitation Tricompartment Offloader (TCO) brace is designed to unload all three knee compartments by reducing compressive forces caused by muscle contraction. This study aimed to determine the effect of the TCO on knee contact forces and quadriceps muscle activity in individuals with knee osteoarthritis. Lower limb kinematics, kinetics, and electromyography data were collected during a chair rise-and-lower. A 3D inverse dynamics model of the lower-leg and foot was used with a sagittal plane knee model to compute knee joint forces...

The purpose of this study was to track platelet-derived growth factor receptor-beta (Pdgfr-β) lineage cells at the site of Achilles tendon injury over time. Pdgfr-β-CreERT2 :Ai9 mice were generated in order to track Pdgfr-β lineage cells in adult mice. A surgical Achilles transection injury model was employed to examine the presence of Pdgfr-β lineage cells in the healing tendon over time, with 5 mice per time point at 3, 7, 14, 28, and 56 days postoperatively. Histology and immunohistochemistry for tdTomato (Pdgfr-β lineage cells), PCNA (proliferating cell nuclear antigen, cell proliferation), and α-SMA (alpha smooth muscle actin, myofibroblasts) were performed...

Adolescent idiopathic scoliosis (AIS) is a spine deformity whose progression during growth is affected by asymmetrical loads acting on the spine. The conservative brace treatment aims to limit the deformity's progression until the end of skeletal growth. This study's objective was to develop a patient-specific finite element model (FEM) simulating immediate in-brace correction and subsequent growth modulation over 2 years of treatment. Thirty-five retrospective AIS cases with documented correction over 2 years were analyzed...

MRI is the gold standard for assessment of soft tissues, however, X-ray based techniques are required for evaluating bone-related pathologies. This study evaluated the performance of synthetic computed tomography (sCT), a novel MRI-based bone visualization technique, compared with CT, for the scoring of knee osteoarthritis. sCT images were generated from the 3T T1-weighted gradient echo MR images using a trained machine learning algorithm. Two readers scored the severity of osteoarthritis in tibiofemoral and patellofemoral joints according to OACT, which enables the evaluation of osteoarthritis, from its characteristics of joint space narrowing, osteophytes, cysts and sclerosis in CT (and sCT) images...

Resiliency consists of three core components, which include presence of adversity, protective factors to overcome adversity, and positive outcomes or growth. Therefore, resiliency aligns with the trauma recovery process. This paper describes development of the Trauma Resiliency Scale (tRS) to quantify the resiliency of trauma patients upon presentation and during recovery. Scale items were proposed and reviewed by an expert panel. Group construct validity testing was performed using both individual and focus group feedback with item analysis...

The assessment of three-dimensional (3D) bony defects is important to inform the surgical planning of hip reconstruction. Mirroring of the contralateral side has been previously used to measure the hip centre of rotation (CoR). However, the contralateral side may not be useful when diseased or replaced. Statistical Shape Models (SSMs) can aid reconstruction of patient anatomy. Previous studies have been limited to computational models only or small patient cohorts. We used SSM as a tool to help derive landmarks that are often absent in hip joints of patients with large acetabular defects...

Articular surface irregularities are often observed in collapsed femoral heads with osteonecrosis, while the effects of the degree of collapse on the articular surface are poorly understood. We first macroscopically assessed the articular surface irregularities on 2-mm coronal slices obtained using high-resolution microcomputed tomography of 76 surgically resected femoral heads with osteonecrosis. These irregularities were observed in 68/76 femoral heads, mainly at the lateral boundary of the necrotic region...

Progressive collapsing foot deformity (PCFD) is characterized by a progressive subluxation of the peritalar bones and respective joints. Two-dimensional conventional radiographs are limited in their ability to visualize the peritalar bones and joints with adequate detail to describe the complex three-dimensional (3D) deformity. An improved understanding of the relationship between joint coverage and deformity would allow clinicians to use coverage analysis to distinguish among the stages of PCFD. The aim of this study was to analyze the joint coverage of the six articular relationships within the talocrural, subtalar, and Chopart joints using weightbearing computed tomography (WBCT) scans...

Autocrine stimulation of tumor cells is an important mechanism for the growth of skeletal tumors. In tumors that are sensitive, growth factor inhibitors can dramatically reduce tumor growth. In this study, our aim was to investigate the effects of Secreted phosphoprotein 24 kD (Spp24) on the growth of osteosarcoma (OS) cells in the presence and absence of exogenous BMP-2 both in vitro and in vivo. Our study demonstrated that Spp24 inhibited proliferation and promoted apoptosis of OS cells as confirmed by 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide assay and immunohistochemical staining...
