Aims: Developing a new effective method of clavicle osteosynthesis.

Methods: The K-wire is inserted along bone fragments (and bone autograft – in case of clavicle defect). Then K-wire is fixed near the breast-bone with the curved or threaded lug. External end of K-wire is strained in external fixation module. When having fracturing console pin with lug is inserted in acromion of frontal plane and is connected to K-wire with short bar. In cases of non-unions and defects two K-wire are inserted (through coracoid and acromion) sagittally. Both of them are strained in half-ring. The K-wire inserted along bone fragments is strained in half-ring (Patent of RF # 1657168).

Results: 238 patients were treated by CoSF: 222 with fractures, 11 – with non-unions, 5 – with defects of clavicle. Complete restoration of shoulder function during of fixation period was registered in 86,1% patients (p< 0,001). Analysis has shown that the main reason of join stiffness were delayed operation. 13,6% of patients have been operated in more than two weeks the injury had occurred, when the contracture already appeared. Pin-tract infection were arised in 3,4% cases, pin-tract osteomyelitis – in 1% cases.

Conclusions: Good and excellent results proved prospective of CoSF as well as improving this method.
