INTRODUCTION One of the primary functions of the proximal tibiofibular joint is slight rotation to accommodate rotational stress at the ankle. Proximal tibiofibular joint dislocation is a rare injury and accounts for less than 1% of all knee injuries. This dislocation has been reported in patients who had been engaged in football, ballet dancing, equestrian jumping, parachuting and snowboarding...

Isolated pisiform dislocation is an uncommon condition, with a limited number of cases reported in the literature. We present unique case 15-year-old male who experienced atraumatic isolated bone his left wrist and presented pain, deformity, ulnar nerve palsy little ring fingers. Radiographic investigations confirmed diagnosis dislocation, patient successfully underwent open reduction, stabiliz...

We report a case of a 58-year-old man presenting with a spontaneous and late in-the-bag intraocular lens dislocation to the vitreous. A previous uneventful extracapsular cataract extraction with can-opener style capsulotomy and implantation of a polymethylmethacrylate three-piece lens was performed and, two years after the surgery, the patient developed capsule contraction syndrome with a fibro...

The purpose of this study is to find the uncertainties in the reconstruction of MR compatible ring-tandem intracavitary applicators of high-dose rate image-based brachytherapy treatment planning using rigid registration of 3D MR and CT image fusion. Tandem and ring reconstruction in MR image based brachytherapy planning was done using rigid registration of CT and MR applicator geometries. Verif...

This paper investigates the effect of inserting a ring type barrier on leakage flow of brush seals with different bristles clearances (the distance between bristle pack tip and rotor surface). The ring is placed on both upstream and downstream sides of the bristles. An axisymmetric CFD model is employed to calculate radial pressure distribution along backing plate, axial pressure variation on r...

DESCRIPTION A 26-year-old right-handed man presented with pain in his right ring finger after a physical altercation. Deformity and swelling in the distal interphalangeal (DIP) joint was evident. There was no open injury or sensory loss; flexion and extension were limited secondary to pain. X-ray showed posterior dislocation of the ring finger DIP joint without fracture.

A PERUSAL of the literature suggests that the ring-shaped tumour (cristallwulst) of regenerating lens substance first described by Soemmerring (1828) is not uncommon but may pass unrecognized unless the pupil is very wide, a congenital or operative coloboma of the iris is present, or the ring has become dislocated (Figs 1 and 2). Not more than fourteen cases of dislocation have so far been publ...
