BACKGROUND: This pilot study aimed to ascertain whether the local application of ascorbic acid (AA), of T3 , and of rat (r) bone marrow mesenchymal stem cells (BMSCs), alone or in all possible combinations, promoted healing after an Achilles tendon injury in a rat model. METHODS: An Achilles tendon defect was produced in 24 6-8-week-old male inbred Lewis rats. The animals were then randomly divided into eight groups of three rats each. The tendon defect was filled with 50 μL of phosphate-buffered saline (PBS) containing (1) 50 μg/mL AA (AA group), (2) 10-7  M T3 (T3 group), (3) 4 × 106 rBMSCs (rBMSC group), (4) 50 μg/mL AA + 10-7  M T3 (AA + T3 group), (5) 4 × 106 rBMSCs + 50 μg/mL AA (rBMSC + AA group), (6) 4 × 106 rBMSCs + 10-7  M T3 (rBMSC + T3 group), (7) 4 × 106 rBMSCS + 50 μg/mL AA + 10-7  M T3 (rBMSC + AA + T3 group), and (8) PBS only (control group: CTRL)...

BACKGROUND: Unstable sacral fractures are high-energy injuries and comprise polytrauma. Internal fixation to enable withstanding vertical loads is required to get up early from the bed after an unstable sacral fracture. We developed a new minimally invasive surgical (MIS) procedure for unstable pelvic ring fractures and reported it in Japanese in 2010. We presented our minimally invasive surgical technique of crab-shaped fixation for the treatment of unstable pelvic ring fractures and report on its short-term outcomes...

BACKGROUND: Polymethylmethacrylate (PMMA) is used for local antimicrobial delivery in orthopedic infection. Oritavancin is a long half-life lipoglycopeptide with broad activity against Gram-positive bacteria. Herein, we addressed if 7.5% w/w oritavancin mixed into PMMA affects PMMA strength and whether it elutes from PMMA, compared to vancomycin. METHODS: Elution was assessed by placing an oritavancin- or vancomycin-loaded bead in a flow system with human plasma...

INTRODUCTION: While locking plates have markedly improved fixation of proximal humerus fractures, a cohort of fractures remains difficult to treat. This cohort has been identified as fractures with marked medial comminution and varus deformity. Loss of reduction and fixation failure are the most frequently reported complications for this cohort. We report the use of an orthogonal 1/3 tubular plate to augment the proximal humerus locking plate. METHODS: The subject underwent osteosynthesis for a four-part proximal humerus fracture with medial comminution...

BACKGROUND: Platelet-rich plasma (PRP) is autologous in origin and contains a high concentration of platelets which is a source of various growth factors. Previous studies have suggested that PRP has a positive effect in accelerating fusion by an autologous bone graft in a lumbar fusion. The role of PRP on artificial bone grafts in spinal fusion remains controversial. In this study, positive effect on spinal fusion by PRP was hypothesized; in vitro and in vivo studies were designed to test this hypothesis...

BACKGROUND: Total hip arthroplasty for adult patients with a history of infection of the hip in childhood could be a more technically demanding procedure due to complicated anatomy and the possibility of reinfection. Here, we conducted a mid-term analysis of clinical outcomes in such patients after primary cementless total hip arthroplasty (THA). METHODS: We reviewed 101 patients (101 hips; 51 men; mean age, 52.3 years) who underwent cementless THA between 2008 and 2015, at a mean of 24 years (range, 11-43) since the resolution of childhood hip infection...

#19
Yang Ruen Zheng, Yung Chang Lu, Chung Ting Liu
BACKGROUND: Clavicle fractures are common clinical problems, accounting for approximately 10% of all fractures. Neer's type II fractures disrupt the integrity of the coracoclavicular ligament and, therefore, are inherently unstable, requiring an extended period time to achieve bone union and being associated with a high rate of non- or malunion. Restoration of the stability of the distal clavicle is an important factor to decrease the rate of non- or malunion. As such, the aim of our study was to describe our technique of indirect osteosynthesis, using a minimally invasive closed-loop double endobutton (TightRope) technique for fixation of unstable (Neer's type II) distal clavicle factures, and to evaluate the short-term clinical outcomes...
