Abstract
Presented the experience of the application of stable osteosynthesisby three Kirschner wires on diaphyseal fractures of the metacarpal bones at 74 patients.Indications for osteosynthesiswas opened (6%), closed (94%), non-united, mal-unitedfractures and false joints of metacarpal bonesdiaphysis. Patients were performed intraosseous anesthesia atdistal epimetaphysisarea of radial bone.Describeda method of operation extramedullaryosteosynthesis using three Kirschner wires. Also,describedmethod of wedge osteotomy for full recovery of hand function. Good results were obtained in 83.1% of patients, satisfactory at 13.6%, and unsatisfactory results in 3.4% of patients
Highlights
Treatment of fractures of the metacarpal bones is still a difficult part of Hand Surgery
Intramedullary osteosynthesis pin allows for reliable fixation of fragments, provides extra-articular holding metal fixating, contributes in less traumatization of interosseous muscles and longitudinal arch brush and can be apply for multiple fractures of metacarpal bones
Despite the simplicity and reliability of the diafixation method, its application is limited for multiple fracture of the metacarpal bone and does not eliminate the rotational displacement of bone fragments
Summary
Treatment of fractures of the metacarpal bones is still a difficult part of Hand Surgery. Extra focal osteosynthesis external fixation finds a wider application but this method is indicated only at fragmented, peri and intra-articular fractures [Beidik, 2006; Miguleva, 2004; Zerdedzhi, 2008]. Despite the simplicity and reliability of the diafixation method, its application is limited for multiple fracture of the metacarpal bone and does not eliminate the rotational displacement of bone fragments. To eliminate these disadvantages, we have developed a modified diafixation method for bone fragments fracture of the metacarpal bones of the hand
