In this study, we aimed to explore surgical variations in the Femoral Neck System (FNS) used for stable fixation of Pauwels type III femoral neck fractures. Finite element models were established with surgical variations in the distance between the implant tip and subchondral bone, the gap between the plate and lateral femoral cortex, and inferior implant positioning. The models were subjected to physiological load.Aims

There has been a long-standing debate as to whether medullary or periosteal flow is the dominant vascular supply during the healing of
With the ageing population, fragility fractures have become one of the most common conditions. The objective of this study was to investigate whether microbiological outcomes and fracture-healing in osteoporotic bone is worse than normal bone with fracture-related infection (FRI). A total of 120 six-month-old Sprague-Dawley (SD) rats were randomized to six groups: Sham, sham + infection (Sham-Inf), sham with infection + antibiotics (Sham-Inf-A), ovariectomized (OVX), OVX + infection (OVX-Inf), and OVX + infection + antibiotics (OVX-Inf-A). Open femoral diaphysis fractures with Kirschner wire fixation were performed. Aims

We reviewed 63 patients with fractures of the distal tibial metaphysis, with or without minimally displaced extension into the ankle joint. The fractures had been caused by two distinct mechanisms, either a direct bending force or a twisting injury. This influenced the pattern of the fracture and its time to union. All fractures were managed by statically locked intramedullary nailing, with some modifications of the procedure used for
We compared the results of primary ultrasonographic examination of 163 children with 224 suspected fractures with the subsequent radiological findings. The aim was to assess the value of ultrasound in the diagnosis of fractures in children. We found a good correlation for fractures of the long bones of the upper and lower limbs. Ultrasound was most reliable for the detection of simple femoral and humeral
The aim of this study was to investigate if there are differences in outcome between sliding hip screws (SHSs) and intramedullary nails (IMNs) with regard to fracture stability. We assessed data from 17,341 patients with trochanteric or subtrochanteric fractures treated with SHS or IMN in the Norwegian Hip Fracture Register from 2013 to 2019. Primary outcome measures were reoperations for stable fractures (AO Foundation/Orthopaedic Trauma Association (AO/OTA) type A1) and unstable fractures (AO/OTA type A2, A3, and subtrochanteric fractures). Secondary outcome measures were reoperations for A2, A3, and subtrochanteric fractures individually, one-year mortality, quality of life (EuroQol five-dimension three-level index score), pain (visual analogue scale (VAS)), and satisfaction (VAS) for stable and unstable fractures. Hazard rate ratios (HRRs) for reoperation were calculated using Cox regression analysis with adjustments for age, sex, and American Society of Anesthesiologists score.Aims

We have reviewed retrospectively 68 revisions of the femoral component in arthroplasties of the hip in 65 patients, using impaction bone grafting, at a median of three years (1 month to 6 years). We employed the cemented Exeter X-Change technique in 36 patients and the uncemented Bi-Metric allografting method in 32. The 37 bone defects were grade 3 or grade 4 on the Endo-Klinik classification. The Mayo hip score improved from a mean of 32 (. sd. ± 18) to 62 (. sd. ± 15). Most (25) of the 34 complications occurred in grade-3 and grade-4 defects; nine were intraoperative
From 1988 to 1994 a consecutive series of 1000 fractures of the adult clavicle was treated in the Orthopaedic Trauma Clinic of the Royal Infirmary of Edinburgh. In males, the annual incidence was highest under 20 years of age, decreasing in each subsequent cohort until the seventh decade. In females, the incidence was more constant, but relatively frequent in teenagers and the elderly. In young patients, fractures usually resulted from road-traffic accidents or sport and most were diaphyseal. Fractures in the outer fifth were produced by simple domestic falls and were more common in the elderly. A new classification was developed based on radiological review of the anatomical site and the extent of displacement, comminution and articular extension. There were satisfactory levels of inter- and intraobserver variation for reliability and reproducibility. Fractures of the medial fifth (type 1), undisplaced
We report a prospective study of the incidence of fractures in the adult population of Edinburgh, related to age and gender. Over a two-year period, 15 293 adults, 7428 males and 7865 females, sustained a fracture, and 5208 (34.0%) required admission. Between 15 and 49 years of age, males were 2.9 times more likely to sustain a fracture than females (95% CI 2.7 to 3.1). Over the age of 60 years, females were 2.3 times more likely to sustain a fracture than males (95% CI 2.1 to 2.4). There were three main peaks of fracture distribution: the first was in young adult males, the second was in elderly patients of both genders, mainly in metaphyseal bone such as the proximal femur, although
We made a prospective study of 116 patients with tibial
In a consecutive series of 498 patients with 528 fractures of the femur treated by conventional interlocking intramedullary nailing, 14 fractures of the femoral neck (2.7%) occurred in 13 patients. The fracture of the hip was not apparent either before operation or on the immediate postoperative radiographs. It was diagnosed in the first two weeks after operation in three patients and after three months in the remainder. Age over 60 years at the time of the femoral fracture and female gender were significantly predictive of hip fracture on bivariate logistic regression analysis, but on multivariate analysis only the location of the original fracture in the proximal third of the femur (p = 0.0022, odds ratio = 6.96, 95% CI 2.01 to 24.14), low-energy transfer (p = 0.0264, odds ratio = 15.56, 95% CI 1.38 to 75.48) and the severity of osteopenia on radiographs (p = 0.0128, odds ratio = 7.55, 95% CI 1.54 to 37.07) were significant independent predictors of later fracture. Five of the 19 women aged over 60 years, who sustained an osteoporotic proximal
Osteopetrosis (OP) is a rare hereditary disease that causes reduced bone resorption and increased bone density as a result of osteoclastic function defect. Our aim is to review the difficulties, mid-term follow-up results, and literature encountered during the treatment of OP. This is a retrospective and observational study containing data from nine patients with a mean age of 14.1 years (9 to 25; three female, six male) with OP who were treated in our hospital between April 2008 and October 2018 with 20 surgical procedures due to 17 different fractures. Patient data included age, sex, operating time, length of stay, genetic type of the disease, previous surgery, fractures, complications, and comorbidity.Aims

Fibrinolysis plays a key transition step from haematoma formation to angiogenesis and fracture healing. Low-magnitude high-frequency vibration (LMHFV) is a non-invasive biophysical modality proven to enhance fibrinolytic factors. This study investigates the effect of LMHFV on fibrinolysis in a clinically relevant animal model to accelerate osteoporotic fracture healing. A total of 144 rats were randomized to four groups: sham control; sham and LMHFV; ovariectomized (OVX); and ovariectomized and LMHFV (OVX-VT). Fibrinolytic potential was evaluated by quantifying fibrin, tissue plasminogen activator (tPA), and plasminogen activator inhibitor-1 (PAI-1) along with healing outcomes at three days, one week, two weeks, and six weeks post-fracture.Aims
