OBJECTIVE: To measure the axial stretching force produced by the small splint fixation system in the treatment of the fracture. METHODS: Dumbbell shaped plexiglass was machined to model the bone shaft with expanded two ends. Force transducer was set at the model fracture site to measure the stretching force produced by fracture fixation of the small splint with cloth aqueous bag that simulated the muscles and other soft tissue underneath. RESULTS: There was positive relationship between the axial stretching force produced at the model fracture site and the transverse pressing force exerted by the external plates...

Introduction: Osteosynthesis of the femur using an interlocking nail is the gold standard for treating diaphyseal fractures of the femur. There are two established entry points for the antegrade interlocking nails which is the piriformis fossa or the greater trochanter. It has been reported that varus malalignment was frequently seen in proximal femur fracture which were treated with interlocking nail utilizing the greater trochanter entry point. The study was done to find out if the problem was of significance...

Background and Aims: Boraginales are often characterized by a dense cover of stiff, mineralized trichomes, which may act as a first line of defence against herbivores. Recent studies have demonstrated that the widely reported silica and calcium carbonate in plant trichomes may be replaced by calcium phosphate. The present study investigates mineralization patterns in 42 species from nine families of the order Boraginales to investigate detailed patterns of mineralization and the possible presence of a phylogenetic signal in different mineralization patterns...

BACKGROUND: American Academy of Orthopaedic Surgeons (AAOS) Clinical Practice Guidelines for pediatric femoral shaft fractures indicate titanium elastic nails (TENs) for children 5 to 11 years old. Growing evidence suggests these fractures may also be treated with open or submuscular plating. The purpose of this study was to compare estimated blood loss (EBL), operative time, fluoroscopy time, cost, and subjective and objective pain scores between TENs and plating techniques used in 5- to 11-year-old children with midshaft femur fractures based on length stability...

Acetabular and spino-pelvic (SP) morphological parameters are important determinants of hip joint dynamics. This prospective study aimed to determine whether acetabular and SP morphological differences exist between hips with and without cam morphology and between symptomatic and asymptomatic hips with cam morphology. A cohort of 67 patients/hips was studied. Hips were either asymptomatic with no cam (Controls, n = 18), symptomatic with cam (n = 26) or asymptomatic with cam (n = 23). CT-based quantitative assessments of femoral, acetabular, pelvic and spino-pelvic parameters were performed...

While many femoral neck fractures can be reliably treated with surgical intervention, Pauwels III femoral neck fractures in the young adult population continue to be a challenging injury, and there is no consensus on optimal treatment. As such, there are past and ongoing biomechanical studies to evaluate the fixation provided by different constructs for this inherently unstable fracture. While many investigations rely on cadavers to evaluate the biomechanical performance of a construct, significant inter-subject variability can confound the analysis...

An error-controlled mesh refinement procedure for needle insertion simulations is presented. As an example, the procedure is applied for simulations of electrode implantation for Deep Brain Stimulation. We take into account the brain shift phenomena occurring when a craniotomy is performed. We observe that the error in the computation of the displacement and stress fields is localised around the needle tip and the needle shaft during needle insertion simulation. By suitably and adaptively refining the mesh in this region, our approach enables to control, and thus to reduce, the error whilst maintaining a coarser mesh in other parts of the domain...

RATIONALE: Although numerous reconstruction protocols have been reported for lower leg trauma, those for distal leg trauma remain few. We present the case of a woman with an implant exposure wound, who was successfully treated through fat grafting, without major flap surgery. PATIENT CONCERNS: An 83-year-old woman with an exposed implant in lower extremity received reconstruction surgery once and the surgery failed. She refused additional major surgery and negative pressure wound therapy...

Arm wrestling places significant torque on the humeral shaft. A spiral distal humeral shaft fracture is an unusual but significant injury that can result. Of 93 patients who presented between 2009 and 2017 with closed humeral shaft fractures that were managed nonoperatively, 9 sustained the fractures while arm wrestling. Outcomes were compared with those of all other patients with nonoperatively managed humeral shaft fractures sustained through other mechanisms. The Student's t test was used to compare cohorts...

For patients with prior coronary artery bypass graft surgery, reaching lesions in native coronary arteries distal to the anastomosis of bypass grafts can be challenging due to long distance between the graft ostium and the lesion and significant tortuosity that needs to be traversed. We describe one such lesion in a patient presenting with non-ST segment elevation myocardial infarction and cardiogenic shock. The lesion was successfully treated using a variety of strategies, including use of a short guide catheter, long guidewire, a guide catheter extension, long shaft balloons and stents, and short length stents...

We previously reported safety and usefulness of transradial iliac artery stenting using 6 Fr guiding sheath. However, radial artery occlusion was a major limitation of this procedure. We analyzed the safety and utility of slender transradial iliac artery stenting using a 4.5 Fr guiding sheath to prevent radial artery occlusion. We performed transradial iliac artery stenting in left radial artery, using a 4.5 Fr sheath incorporating a shaft length of 110 cm, for 34 lesions in 29 patients. Transradial intervention was attempted at the discretion of the operator...

The ligamentum teres (LT) is perceived to contribute to hip stability and proprioception. LT incompetence can lead to pain and instability, which may play a role in chondral damage. Hip arthroscopy plays a role in diagnosing and treating LT tears. Reconstruction of the LT is feasible, but careful attention needs to be paid to tunnel positioning, graft material, graft length, and fixation methods. An anatomic femoral tunnel should exit at the fovea capitis on the femoral side, whereas the location for safe placement of the acetabular attachment is thought to be in the posteroinferior part of the cotyloid fossa...

Spinal fusion and bone defect after injuries, removal of bone tumors, and infections need to be repaired by implantation. In an aging society, recovery from these procedures is often difficult. In this study, we found that injection of SPG-178 leads to expression of several bone marker genes and mineralization in vitro, and revealed a significantly higher degree of newly formed bone matrix with use of SPG-178 in vivo. MC3T3-E1 cells were used to evaluate osteoblast differentiation promoted by SPG-178. To analyze gene expression, total RNA was isolated from MC3T3-E1 cells cultured for 7 and 14 days with control medium or SPG-178 medium...

Intraosseous hemangiomas are uncommon benign vascular tumors. Here the authors report a case of intraosseous hemangioma of the radial shaft in a 2-year-old boy, surgically treated by tumor mass resection and application of calcium sulfate pellets with no signs of relapse over a 2-year follow-up. Moreover, the lesion healed with new bone formation, and the last plain radiographs suggested homogenous normal trabecular bone density. The radius grew in length and remodeled to an almost normal shape. Clinically, elbow flexion-extension and forearm pronation and supination were within normal limits at the last follow-up visit...

In social insects, nests are very important structures built to provide a protected microhabitat for immature development and food storage and are the places where most interactions between all members of a colony occur. Considering that nest architecture is an important behavioural trait that can clarify essential points of the social level of the species, here we describe the architectural model of the Ponerinae ant Odontomachus chelifer. Five subterranean nests were excavated; one of them filled with liquid cement for extraction of casts of chambers, shafts and tunnels...
