Accurate spatial location of joint center (JC) is a key issue in motion analysis since JC locations are used to define standardized anatomical frames, in which results are represented. Accurate and reproducible JC location is important for data comparison and data exchange. This paper presents a method for JC locations based on the multiple regression algorithms without preliminary assumption o...

Background: Prevalence of recurrent shoulder dislocation in patients taking tramadol has not been studiedyet so, this study aims to study the recurrent shoulder dislocation following tramadol induced seizure. Methods: In this cross-sectional study, 205 patients with recurrent shoulder dislocation complaints (2 or more) referred to Shafa Orthopedic and Iranmehr hospitals Tehran, Iran, from Oc...

absractall perilunate fracture-dislocations combine bone avulsions, ligament disruptionand fractures in different forms. the most frequent pattern is the dorsal transscaphoidperilunate fracture-dislocation. the reported risk of missed initial diagnosisin perilunate dislocations is as high as 20%. concerning pathomechanics of theperilunate fracture-dislocation, it should be noted that most dorsa...

introduction arthrogryposis multiplex congenita (amc) with incidence of 1 in 3000 of births is characterized by multiple rigid joint and soft-tissue contractures. case presentation we present a case of amc with severe soft tissue and joints contractures, especially joints of lower limb and elbows, bilateral complete dislocation of hips (cdh) and knees (cdk) (type iii), bilateral elbow joint dis...

A unilateral (Left side) additional Clavicular head of sternocleidomastoid (SCM) was found during routine dissection of head and neck region in 43 years old male cadaver. The additional slip was extended its origin almost whole the length of middle third of clavicle. The fusion failure or abnormal mesodermal splitting during development may be the reason for present variation at origin of stern...

For comminuted shaft fracture of clavicle, the operative goal, aside from sound bone healing without complications of direct reduction, is maintenance of the original length in order to maintain the normal biomechanics of adjacent joint. Our bridge plating technique utilizing distraction through a lumbar spreader was expected to be effective for restoring clavicular length with soft tissue pres...

Objectives Cervical nerves block cannot be performed on some patients because of the risk of phrenic nerve paralysis. To overcome this limitation, we discovered the site of selective only supraclavicular nerve block at the subclavian site. Case report We present the case of a 62-year-old woman with clavicular fracture. We performed a selective block of the supraclavicular nerve and the fifth ...

We performed endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) on a patient presenting with an asymptomatic peripancreatic mass-like lesion. The aspiration cytologic finding was class II. On positron emission tomography-computed tomography (PET-CT), there were hot spots in the left supra-clavicular lymph node and the peripancreatic lesion. A whole biopsy of the left supra-clavicular...

Clavicular tuberculosis is a rare entity, an unusual case of skeletal tuberculosis. We report a case of rare presentation of clavicular tuberculosis as a non-healing ulcer in the medial two-third and lateral one-third of the clavicle. The clinical picture was confusing because of the development of foul-smelling discharge due to secondary infection. The diagnosis is rarely suspected before biop...
