Management of long bone defects occurring in accidents or war injuries is a difficult problem, From 1978 to 1986, 11 patients were treated for long bone defects of the humerus ( 10 cases) and radius (one case), using free vascularized fibular transfer by microsurgical technique .The patients were followed for 4 months and in all of them, selective angiography and scanning revealed exellent...

The objective of the current study was to determine the anatomical features of the auditory ossicles inhamster. Twenty temporal bones from 10 adult hamsters, weighing 275-300 g were used. After dissectingthem, the features of the ossicles were assessed with an ocular micrometer and photographed by astereomicroscope. Finally, all data were evaluated and analysed using the Sigma Statt software. T...

We describe a case of intramuscular vascular malformation with extensive ossification within the posterior compartment muscles of leg which grossly mimicked long bone leading to equinus deformity of foot. Phleboliths and calcifications are characteristic of vascular malformations, while massive ossification is rare. To our knowledge, no extensive ossified vascular malformation within the leg mu...

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...

In this research, anatomical descriptions of the structure of the temporal bone and auditory ossicles have been performed based on dissection of ten guinea pigs. The results showed that, in guinea pig temporal bone was similar to other animals and had three parts; squamous, tympanic and petrous .The tympanic part was much better developed and consisted of oval shaped tympanic bulla with many re...

        Ewing's sarcoma is a relatively common malignant bone tumor that typically occurs in long bone diaphyses of adolescents and young adults of 10-30 years old. Often times, all Ewing's sarcoma of bone have radiographic abnormalities. Diagnosis is usually delayed and can be misdiagnosed as osteomyelitis. Bone to bone metastasis occurs, but soft tissue retro bulbar metastas...
