RATIONALE Osteopetrosis is a rare disease that predominantly occurs in descendants of inbreeding families. In the case of fractures happen in patients with osteopetrosis, the choice between operative or conservative treatment is still controversial. Open reduction and internal fixation (ORIF) is a conventional treatment for fractures, and it possesses more applicability than conservative treatm...

BACKGROUND Femoral neck fractures typically occur as a result of high-energy mechanisms among non-geriatric patients. Complications, including femoral neck shortening, non-union, and avascular necrosis, are relatively common after the internal fixation of this fracture pattern. These complications have serious effects on young patients. The Pauwels classification, which is the first biomechanic...

Double network (DN) gels, consisting of a brittle first and flexible second network, have been known to be extremely tough and functional hydrogels. In a DN gel subjected to force, the brittle first network breaks prior to the fracture of the flexible network. This process, referred to as internal fracture, dissipates energy and increases the energy required to completely fracture DN gels. Such...

objective: to determine the effects of platelet rich plasma prp on healing rates of long bone non-:union: fracture. method: this was a randomized double-blind placebo controlled clinical trial being performed in a 12-month period. we included 75 adult (>18 years) patients suffering from long bone (femur, tibia, humerus and ulna) non-:union: fracture who were randomly assigned to receive 5ml prp...

BACKGROUND Supracondylar fracture of humerus is the second most common fracture in children which account for 60-75% of all fractures around the elbow. There are various treatment modalities for type-III fracture, i.e., closed reduction and casting, skeletal traction, close reduction and percutaneous pinning and open reduction and internal fixation. This study was conducted to see the outcome o...

BACKGROUND The aim of the present study is to analyze the incidence of hip fracture as a complication of admissions to internal medicine units in Spain. METHODS We analyzed the clinical data of 2,134,363 adults who had been admitted to internal medicine wards. The main outcome was a diagnosis of hip fracture during hospitalization.Outcome measures included rates of in-hospital fractures, leng...

determination of the optimum loading path (internal pressure- axial feeding) to restrict the bursting, buckling and wrinkling through tube hydroforming process is necessary to produce an acceptable tube. in this paper, the wrinkling and fracture criteria are implemented to an finite element code devoted to the simulation of tube hydroforming processes. using the ansys parametric design language...

Limited data are available on the use of internal fixation in combat zone hospitals. The authors performed a retrospective review of 713 surgical cases during 2 Operation Enduring Freedom deployments to a Level III theater hospital in 2007 and 2009 to 2010. The epidemiology and short- to intermediate-term outcomes of patients treated with internal fixation devices were studied. The authors foun...

This study aims at diagnosis and rehabilitation of a rare case of deep wound infection and internal fixation rejection in elbow. The patient sustained a distal fracture in the humerus 1 year ago, which was internal fixed. The wound always effused and the elbow had pain and swelling; joint motion was limited. Blood sedimentation rate and C reactive protein level increased, bacterial culture sugg...
