Facial and skull base trauma can cause clinically significant epistaxis. Optimal evaluation and treatment require knowledge of the pertinent vascular and skull base anatomy. We describe a patient with extensive skull base injury and epistaxis in whom CT revealed a fracture through the roof of the nasopharynx and arteriography showed injury to the pterygovaginal (pharyngeal) artery. The fracture...

We proposed a multipronged approach to the management of Freiberg disease. A combined dorsal closing wedge with shortening of the metatarsal and joint debridement and microfracture for treating the Freiberg infarction was done. The hypothesis is that dorsal closing wedge and shortening alone cannot help cartilage regeneration. Addition of micro-fracture aids in cartilage regeneration and debrid...

Superficial thrombophlebitis of the dorsal vein of the penis, known as penile Mondor’s disease, is an uncommon genital disease. We report on a healthy 44-year-old man who presented with painful penile swelling, ecchymosis, and penile deviation after masturbation, which initially imitated a penile fracture. Thrombosis of the superficial dorsal vein of the penis without rupture of corpus cavernos...

offshore pipelines are an effective tool for transportation of oil and gas which are usually assembled by the use of girth welds. since flaws may naturally exist at such welds, fracture assessment of girth welded offshore pipelines is substantial. current fracture assessment procedures like bs 7910 consider identical material properties for the weld and the base metals. however the strength dif...

The stability of the wrist during motion and interrelated motions depends on the capsuloligamentous integrity and the contact surface contours of the carpal bones [1]. Perilunate fracture dislocations (PLFD) are high-energy injuries, produced by wrist hyperextension. It can be palmar or dorsal. Palmar dislocation is extremely rare and result from a fall on the dorsum of the flexed wrist. This i...

BACKGROUND We characterize in this report the mechanism and type of skull fracture in urban populations of Iran. METHODS Data including the general characteristics, mechanism of trauma, abbreviated injury scale, Glasgow coma scale, duration of hospitalization, and outcome of trauma patients registered from 1999 to 2004 were extracted from the Iranian National Trauma Registry database. RESUL...

We present an extreme rare case of traumatic partial avascular necrosis of the lunate after palmar perilunate dislocation with lunate fracture. A 32-year-old female was injured by motorcycle accident with palmar perilunate fracture dislocation and lunate fracture. Scapholunate and lunotriquetrum dislocations were reduced and fixed temporarily. The torn dorsal ligament was repaired. Considering ...

This study aims to evaluate the biomechanical mechanism of fixation systems in the most frequent T-shaped acetabular fracture using finite element method. The treatment of acetabular fractures was based on extensive clinical experience. Three commonly accepted rigid fixation methods (double column reconstruction plates (P × 2), anterior column plate combined with posterior column screws (P + PS...

abstract background: distal radial fracture is one of the most common fractures of the skeletal system. although it has been believed to be a simple fracture with excellent outcomes, practical operations’ results have always been undesirable and even poor. the goal of this study was to compare two methods of treatment “pin and plaster and precautious pin fixation in patients with unstable extra...
