The fixation of labelled sulphate ion, 35SO4, is a measure of chondroitin-sulphate synthesis by cartilage cells, and a most satisfactory way of testing the viability of these cells (Curran and Gibson, 1956). In the case of human tissues, the test must be made in vitro, by incubating suitable slices of cartilage, obtained at biopsy or necropsy, in a medium containing a known amount of sulphur is...

Partial meniscectomy is believed to change the biomechanics of the knee joint through alterations in the contact of articular cartilages and menisci. Although fluid pressure plays an important role in the load support mechanism of the knee, the fluid pressurization in the cartilages and menisci has been ignored in the finite element studies of the mechanics of meniscectomy. In the present study...

Image Acquisition Ultrasonography of the larynx can be performed using standard ultrasound equipment suitable for musculoskeletal examinations. A 7-10 megahertz linear or microconvex transducer provides good resolution and adequate penetration. Sedation is often necessary, as it facilitates patient cooperation and relaxation to allow extension of the head permitting access to the laryngeal regi...

  Background: Electrical injury is daily compromise of our life and upper and lower extremities   are common sites of injury .   Case Presentation: A 23 years old man who had suffered high voltage electrical injury referred   to our center. He had severe left upper extremity burn and suffered from head and thoracic   injuries due to falling down from high altitude.   Treatment: Fasciotomy of th...

Congenital nasal anomalies are rare, with an incidence of 1%–4%. These anomalies range from simple pathology, such as septal deviation or asymmetry of the nostrils, to severe problems accompanied by different craniofacial anomalies [1]. Here, we report the case of a 19-year-old boy with an aesthetic problem of the nose. His physical examination revealed a depression on the supratip area of his ...

Abstract Purpose: Skeletal staining is a way to study the effect of many chemical or herbal substances on development of bones and cartilages in order to record the level of probable deformity.This article aimed to present a modified protocol to make all skeletal studies on laboratory animals possible. Materials and Methods: The important notes about skeletal staining were fixing by ethan...

Objective: to demonstrate the effectiveness of combination of radial extracorporeal shock wave therapy and muscle energy technique on pain, range of motion, and neck function of the individuals with active trigger points of upper trapezius muscle. Method: Fifty-four (54) participants with active TrPs of upper trapezius muscle were participated and randomly divided into three groups. Group A (...

UNLABELLED Patients with unilateral cleft lip display characteristic nasal changes that are independent of the degree of deformity. Defenders of the intrinsic theory consider these deformities to be due to embryogenic alterations of the alar nasal cartilages. Those that propose the extrinsic theory defend the thesis that the deformity is due to disorganization of the perioral muscles deformed b...

PURPOSE OF THE STUDY In this study, our aim is to examine the effect of proximal fibular osteotomy on knee and ankle kinematics with finite element analysis method. MATERIAL AND METHODS One 62-year-old, female volunteer's radiologic images were used for creating lower limb model. Osteotomized model (OM) which was created according definition PFO non-osteotomized (NOM) created. To obtain a stres...

Discoid cartilage was first described in 1889 by Young, and for long was found affecting only the lateral cartilage. The “ snapping knee “ was described as a clinical sign of this condition by Kroiss in 1910. In 1930 Watson Jones described a ring-shaped medial cartilage in a thirty-four-year-old man with clicking at the inner side of his knee ; there had been no history of injury. The cartilage...
