a 25-year-old man was admitted in hospital due to right side hemopneumothorax secondary to car accident. a chest tube was inserted. during the hospitalization days, chest ct scan revealed a 3cmx3 cm oval-shaped density located in the right upper lobe. since he was in a good general condition, he was discharged from hospital after removal of chest tube and a follow-up chest ct-scan was recommend...

The purpose of this study was to compare the acetabular component alignment in patients undergoing primary total hip arthroplasty (THA) via 3 surgical techniques: direct anterior using intraoperative fluoroscopy, posterolateral using an external alignment guide (posterolateral conventional), and posterolateral using computer navigation (posterolateral navigated). Two surgeons performed the dire...

Abstract Introduction Cystic mediastinal lymphangiomas (CML) are exceedingly rare, representing <1% of cystic (CL), and typically present before 2 years age. Few cases describe adult presentations solitary CML none symptomatic with ‘mass-effect’ complications. We an incidental finding a causing mass effect complications our definitive surgical management. Case Report A 44-year-old Caucas...

OBJECT Posterior lumbar interbody fusion (PLIF) was developed to overcome the limitations of posterolateral fusion in correcting spinal deformity and maintaining lumbar lordosis. In this study the authors compare the biomechanical effects of three different posterior reconstructions on the adjacent motion segment. METHODS Ten calf spinal (L2-S1) specimens underwent nondestructive flexion-exte...

OBJECTIVE Whether video-assisted thoracic surgery (VATS) is associated with less shoulder dysfunction when compared with posterolateral thoracotomy (PLT) remains unclear. We therefore conducted this prospective study to assess the shoulder function in patients following major lung resection using either the VATS or PLT approach. METHODS Twenty-nine consecutive patients were prospectively recr...

BACKGROUND Chronic post-thoracotomy pain (CPTP) consists of different types of pain. Some characteristics of CPTP are the same as those of recognized neuropathic pain syndromes. OBJECTIVE We aimed to determine the safety and efficacy of gabapentin (GP) in comparison to naproxen sodium (NS) in patients with CPTP. METHODS Forty consecutive patients with CPTP after posterolateral/lateral thora...

The article published in CHEST by Seelig and associates (January 1999)1 on a very rare complication of occult diaphragmatic hernia has an important theoretical and practical value. Like the authors, we found that the diagnosis of blunt traumatic rupture of the diaphragm may represent a challenge. In the majority of 13 patients managed at our clinic between 1989 and 2000, the fact of blunt thora...

BACKGROUND Diagnosis of partial anterior cruciate ligament (ACL) tears is difficult on magnetic resonance imaging (MRI), particularly the isolated tears of the posterolateral bundle. PURPOSE To describe 2 MRI signs of partial ACL tear involving the posterolateral bundle on conventional knee MRI sequences, specifically, the "gap" and "footprint" signs. STUDY DESIGN Case-control study. METH...

BACKGROUND The efficacy of subpleural analgesia to reduce postoperative pain intensity in patients after lateral thoracotomy is controversial. In this study, we demonstrated the efficacy of two types of subpleural analgesia. METHODS This prospective, controlled, randomized, double-blind trial was performed in Department of Thoracic Surgery of Alzahra Hospital associated with Isfahan Universit...
