To address controversy surrounding the most appropriate comparison group for mild traumatic brain injury (mTBI) research, mTBI patients aged 12-30 years were compared to an extracranial orthopedic injury (OI) patient group and an uninjured, typically-developing (TD) participant group with comparable demographic backgrounds. Injured participants underwent subacute (within 96 hours) and late (3 months) diffusion tensor imaging (DTI); TD controls underwent DTI once. Group differences in fractional anisotropy (FA) and mean diffusivity (MD) of commonly studied white matter tracts were assessed...

Ligament injuries occur frequently, substantially hindering routine daily activities and sports participation in patients. Surgical reconstruction using autogenous or allogeneic tissues is the gold standard treatment for ligament injuries. Although surgeons routinely perform ligament reconstructions, the integrity of these reconstructions largely depends on adequate biological healing of the interface between the ligament graft and the bone. We hypothesized that localized ultrasound-mediated, microbubble-enhanced therapeutic gene delivery to endogenous stem cells would lead to significantly improved ligament graft integration...

BACKGROUND: Cranial cruciate ligament rupture is a prevalent injury in dogs, and tibial plateau leveling osteotomy (TPLO) is one of the preferred surgical techniques. Surgical site infection is a possible complication following TPLO and measurement of serum acute phase proteins is suggested to be a way to early recognize and distinguish postoperative infectious complications from normal postoperative inflammatory conditions. In this study we investigate the changes in concentrations of the systemic inflammatory markers C-reactive protein (CRP) and serum amyloid A (SAA) following tibial plateau leveling osteotomy (TPLO) in dogs and evaluate if deviations from the changes expectedly induced by the surgical procedure are useful in early detection of post-surgical infections...

BACKGROUND: Bone healing and assessment of the state of bone bridging is an important part of clinical orthopedics, whether for fracture healing or for follow up of osteotomy procedures. Tibial tuberosity advancement (TTA) is designed to restore stability in cruciate deficient stifle joints by advancing the tuberosity while creating an osteotomy gap. The current study aims to: 1) compare three different imaging modalities to assess bone healing: ultrasound, radiographs and computed tomography (CT) and, to 2) compare the effect of a gelatinous matrix (GM) versus a demineralized bone matrix mix (DBM mix) on bone healing and bridging of this osteotomy gap in 10 otherwise healthy client-owned dogs with cranial cruciate ligament insufficiency...

Polyetheretherketone is attractive for dental and orthopedic applications due to its mechanical attributes close to that of human bone; however, the lack of antibacterial capability and bioactivity of polyetheretherketone has substantially impeded its clinical applications. Here, a dual therapy implant coating is developed on the 3D micro-/nanoporous sulfonated polyetheretherketone via layer-by-layer self-assembly of Ag ions and Zn ions. Material characterization studies have indicated that nanoparticles consisting of elemental Ag and ZnO are uniformly incorporated on the porous sulfonated polyetheretherketone surface...

Implant degradation products have shown signs of a cutaneous allergic response after implantation of a metal orthopedic replacement, loosening and failure of the joints as well as skin rashes, general fatigue, pain, and impaired wounds and bone healing. The prevalence of contact skin sensitivity in patients with a joint replacement device is higher than that in the general population. This delayed hypersensitivity to metallic orthopedic implants is more clearly defined and is a contributing factor to implant failure...

Osteoimmunology has revealed the importance of a favorable immune response for successful biomaterial-mediated osteogenesis. Boron-incorporated calcium silicate (Ca11 Si4 B2 O22 , B-CS) coating has been reported as a potential candidate for improving osteogenesis in orthopedic applications in vitro. However, relatively little is known about its effects on the immune response and subsequent osteogenesis. In this work, the immunomodulatory properties of the B-CS coating and its specific mechanism of action were explored...

Although many treatment modalities are available for Morton's neuroma, the injection of the neuroma with alcohol has gained popularity. However, recently, some investigators have observed a progressive deterioration in pain scores for patients initially pain free after the treatment. The purpose of the present retrospective comparative study was to determine whether mechanical metatarsalgia is related to symptom recurrence. We included 104 consecutive cases of ultrasound-guided alcohol injection for Morton's neuroma in 92 patients...

Nonoperative treatment of an injured ulnar collateral ligament of the thumb metacarpophalangeal (MCP) joint (skier's thumb without a Stener lesion) is managed by immobilization. A splint is applied on the radial side with the thumb in slight flexion to immobilize the MCP joint and allow motion in the interphalangeal joint. Thermoplastic splints are mainly used for daily activities with the advantage of custom fabrication for optimal comfort. To immobilize the thumb during surgical procedures performed by an orthopedic surgeon, splints made of sterilizable materials are needed but not yet available to our knowledge...

Polyetheretherketone (PEEK) is a high-performance semicrystalline thermoplastic polymer that is widely used in the orthopedics treatment. However, due to its biological inertness, the surface modification of PEEK using different methods to improve the biocompatibility remains a significant challenge. Herein, we attempted to use the covalently coating of phosphorylated gelatin loaded with bone morphogenetic protein 2 (BMP-2) on hydroxylated micro-porous PEEK films for enhancing the biological activity. Environmental scanning electron microscope (ESEM), fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS) and water contact angle measurements were applied to characterize the surface of modified or untreated PEEK films...
