Despite all modern surgical techniques, skin flap that is considered as the main method in most reconstructive surgeries puts the skin tissue at danger of necrosis and apoptosis derived from ischemia. Therefore, finding a treatment for decreasing the apoptosis derived from flap ischemia will be useful in clinic. In present study, we evaluated the effect of azelaic acid 20% and finasteride on ex...

Background: Skin flap grafting is a popular approach for reconstruction of critical skin and underlying soft tissue injuries. In a previous study, we demonstrated the beneficial effects of two 5α-reductase inhibitors, azelaic acid and finasteride, on tissue survival in a rat model of skin flap grafting. In the current study, we investigated the involvement of nitric oxide and inducible nitric o...

case report: we report a 44-year-old man with right femoral nerve palsy following delayed reduction of an anterior dislocation of hip. conclusion: two months after closed reduction, complete clinical recovery of right femoral nerve was achieved and the patient was able to resume his job. introduction: incidence of nerve injury in traumatic hip dislocations is up to 10 %. sciatic nerve is the mo...

isolated scaphoid dislocation is a rare injury of the wrist. to our knowledger, only 22 cases of isolated scaphoid dislocation have been reported in enghish-language literature and we could find only one case with pure radial dislocation. we present a 34-year-old man with isolated pure radial scaphoid dislocation that was treated by open reduction and repair of the scapholunate ligament and pin...

habitual dislocation of the hip (hdh) in children is a rare entity and can be a causative factor for popping or snapping hip which is a common problem in children with good prognosis. we report a case of hdh in a 9 year old girl who was suffering from frequent snapping hip at night, its course and treatment process.

BACKGROUND Current teaching suggests increased perfusion in free transverse rectus abdominis myocutaneous (TRAM) flaps over pedicled TRAM flaps, broadening indications for its use in high risk patients. This study compared perfusion analysis of free muscle-sparing versus pedicle TRAM flaps in vivo in the peri-operative and late post-operative periods. METHODS The SPY-Elite system using...

BACKGROUND The usage of submental flap is a good method for head and neck reconstruction, but it has some risk also, such as anatomical variations and surgical errors. In this article, we present a modified incision design for the submental flap. METHODS We designed a modified submental flap incision method based on the overlap of the incision outline of the submental flap, platysma myocutane...

BACKGROUND The aim of this study was to identify the factors that affect the progress of a traumatic anterior dislocation of the shoulder. METHODS Two hundred and thirty-eight patients (246 shoulders) with a traumatic anterior dislocation were enrolled in this study. The mean age at the time of surgery was 25 years (range, 14 to 47 years). There were 214 men and 24 women. RESULTS One hundre...

Objectives: Patellofemoral dislocation, the most severe presentation on spectrum of patellar instability, is common in adolescent populations. Trochlear dysplasia an integral component disorder, and procedures aimed at correcting instability by addressing this are often necessary. A theoretical risk injury to distal femoral physis exists these surgeries. At our institution, a thick-flap sulcus ...
