Bipolar dislocation of the clavicle

Abstract

Bipolar dislocation of the clavicle at acromioclavicular and sternoclavicular joint is an uncommon traumatic injury. The conservative treatments adopted in the past is associated with redislocation dysfunction and deformity. A 41 years old lady with bipolar dislocation of right shoulder is treated surgically by open reduction and internal fixation by oblique T-plate at sternoclavicular joint and Kirschner wire stabilization at acromioclavicular joint. The patient showed satisfactory recovery with full range of motion of the right shoulder and normal muscular strength. The case reported in view of rarity and at 2 years followup.

The Unique Bipolar Clavicle Dislocation: A Novel Reconstruction Technique and Case Report

“…Castropil et al reported successful outcomes with semitendinosus allografts for treatment of isolated SCJ dislocations [ 20 ]. Tendon allografts may be a favorable alternative to metal hardware, such as K-wires since there have been several reports of cardiac tamponade and tracheoinnominate artery fistula resulting from the migration of K-wires [ 14 , 21 , 22 ]. Also, a tendon allograft reliably provides flexibility and stability for the treatment of these difficult injuries.…”

Bipolar Dislocation of the Clavicle: A Report of Two Cases with Different Injury Patterns and a Literature Review

“…Many authors implemented various procedures for SCJ augmentation to prevent further recurrence or instability. The techniques they used included fixation with metal devices such as a Kirschner wire [ 11 , 20 , 21 ], cerclage wire [ 13 ], compression screw [ 1 ], T-plate [ 12 ], and hook plate [ 22 ], as well as ligamentous reconstruction with polyester fiber tape [ 4 ], polyester surgical mesh [ 7 ], muscle strip [ 36 ], and tendon graft [ 23 ]. Most of these devices were sufficient to prevent recurrence, but the SCJ has an ROM of a maximum of 40°, and rigid joint bridging fixation may compromise shoulder movement.…”
