AbstractBackground. Primary hyperparathyroidism (PHPT) leads to increased bone turnover, low bone mineral density, and increased fracture risk. These effects are, however, preferentially seen in the distal forearm, which is rich in cortical bone. This study aimed to determine how frequently the distal forearm T score was the worst T score ...

PURPOSE: Graft pretensioning is used in anterior cruciate ligament (ACL) reconstruction to prevent secondary slackening. Its effects on collagen fibrillar ultrastructure are not known. In this study, we hypothesized that graft pretensioning in ACL reconstruction creates ultrastructural changes detectable in scanning electron microscopy (SEM). METHODS: A prospective comparative study was ...

ABSTRACT: BACKGROUND: Flexible intramedullary nailing has emerged as an accepted procedure for paediatric femoral fractures. Present indications include all patients with femoral shaft fractures and open physis. Despite its excellent reported results, orthopaedic surgeons remain divided in opinion regarding its usefulness and the best material used for nails. We thus ...

Children requiring allogeneic hematopoietic stem cell transplantation (alloHSCT) have multiple risk factors for impaired bone accrual. The impact of alloHSCT on volumetric bone mineral density (vBMD) and cortical structure has not been addressed. Tibia peripheral quantitative computed tomography (pQCT) scans were obtained in 55 alloHSCT recipients, ages 5-26 years, a ...

Ruptures of the peroneus longus tendon are uncommon, with a small number of case reports found in published studies. The presence of an os peroneum can predispose the peroneus longus tendon to rupture at the cuboid level with or without concomitant fracture, or fracture through a partite os peroneum. Whether ...

BACKGROUND: Combining closed reduction techniques with minimally invasive plate osteosynthesis (MIPO) or intramedullary nailing is a technically challenging procedure, especially when dealing with complex femoral fractures such as periprosthetic fractures. Cerclage wiring is a well known adjunct for fracture reduction and fixation. However, it is usually performed by open reduction, ...

The incidence of hip fracture, death and the estimated incidence of major osteoporotic fracture in France were used to determine the lifetime and 10-year probability of fracture and incorporated into a probability model (FRAX®) calibrated to the French population. INTRODUCTION: Fracture probabilities in the French population have not been determined. ...

Semi-automatic morphometry is highly reproducible and not time intensive; however, no study has evaluated agreement between semi-automated morphometric methods and the Genant semi-quantitative method performed as a rule by radiologists. Our study shows substantial agreement between both methods; however, semi-automatic morphometry upgrades mild deformities and overestimates the prevalence of fractures. ...

Distraction osteogenesis is one of the common procedures for limb lengthening. However, attempts are being made constantly to establish objective guidelines for early and safe removal of a fixator using a sensitive and quantitative measurement technique. Dual-energy X-ray absorptiometry (DEXA) has been evaluated in the past for understanding callus stiffness, ...

Tibiotalocalcaneal arthrodesis using intramedullary nail fixation is a technically demanding procedure. Periprosthetic fracture in association with tibiotalocalcaneal arthrodesis is a rare occurrence, with relatively few instances reported. The present report describes 2 such instances that occurred after tibiotalocalcaneal arthrodesis using retrograde femoral intramedullary nail fixation. Studies have suggested that a ...

Fractures of the talar neck comprise almost 50% of fractures of the talus and may result in significant long-term morbidity. It is of paramount importance to ensure anatomic reduction of the fracture not only for fracture healing but also for minimizing future posttraumatic arthritic sequelae. In addition to conventional radiographs ...

QUESTIONS/PURPOSES: We determined (1) whether misaligned liner insertion, acetabular shell deformation, entrapment of ...

Complex proximal tibial plateau fractures need surgical treatment to achieve good clinical results. The treatment of this kind of fractures is often complicated either by the patient's compromised general conditions, or by soft tissue damage. The locking plate combines the technical advantages of an angular stable plate with those of ...

ABSTRACT: This study will seek to identify a measurable radiographic index, the Metaphyseal-Diaphyseal Index (MDI) score to determine whether intra-operative fracture in osteoporotic bone can be predicted. A 5 year prospective cohort of 560 consecutive patients, undergoing hemiarthroplasty (cemented or uncemented), was evaluated. A nested case-control study to determine risk ...

Icariin, a plant-derived flavonol glycoside, has been proved as an osteoinductive agent for bone regeneration. For this reason, we developed an icariin-loaded chitosan/nano-sized hydroxyapatite (IC-CS/HA) system which controls the release kinetics of icariin to enhance bone repairing. First, by Fourier transform infrared spectroscopy, we found that icariin was stable in ...

BACKGROUND: Long-bone fractures are very common in trauma centers. The conventional Arbeitsgemeindschaft fur Osteosynthesefragen (AO) technique contributes to most fracture healing problems, and external fixation technology also has several disadvantages, so new techniques are being explored. METHOD: A novel hexapod computer-assisted fracture reduction system based on a 3D-CT image reconstruction ...

Current literature is raising questions regarding this management as opposed to offering operative fixation in some instances. This study addresses the use of the Disabilities of the Arm, Shoulder and Hand (DASH) outcomes measure to identify those that have the ...

ABSTRACT: Composite defects of the fronto-orbital region represent a reconstructive challenge. Total autogenous reconstruction requires a thin pliable skin flap along with a bony component that can be osteotomized predictably. The thoracodorsal artery perforator/scapular bone chimeric flap provides a reliable single-stage method to cover difficult composite forehead defects where local ...

Minimally invasive plate osteosynthesis (MIPO) technique is reported as a satisfactory procedure for the treatment of humeral shaft fractures by the anterior approach by several authors.
