چکیده
Humeral shaft fractures make up from 3 to 5 per cent of the general number fractures. There is a distinct bimodal age distribution patients with diaphyseal humeral Most cases are found among men aged 21-30 years and elderly women 60-80 years. Biomechanical peculiarities bone fragment displacement in an important component further planning patient’s treatment rehabilitation. The aim this article assess possible variants determine role muscle on vector at different levels shaft. Materials methods. study included 50 18 78 comminuted Patients 55 dominated according distribution, 68 cent. In most (62 cent), were caused by certain low-energy traumatic factor. 60 hospitalized within first 24 hours after injury. According A. O. Müller classification, 12B-type constituted 72 total number, 12C made 28 Operative was performed for 76 patients, conservative – has been determined data computer-assisted tomography X-ray photography using typical insertion chart under study. Reliable individual anatomic properties intraoperatively. Results discussion. three groups diagnosed fracture. group comprised senile traumas. second 59 third involved high-energy As result, demonstrated key muscles impacting dislocation fragments multifragmental including: deltoid, greater pectoral, coracobrachial, triangularis, biceps, brachial, latissimus dorsi muscles. Based analysis clinical data, shown interrelations between fracture level traumas, age, sex. Elderly female have out mostly experience fractures, which distal deltoid attaching point. Individuals typically located proximally synergy adduction impact observed that should be taken into account when performing closed reduction as well during operative intervention.

متن کاملHemiarthroplasty for comminuted proximal humeral fractures.
PURPOSE To evaluate early functional outcomes of hemiarthroplasty for 3- or 4-part proximal humeral fractures. METHODS 16 men and 11 women aged 27 to 83 (mean, 56) years underwent hemiarthroplasty for comminuted 3-part (n=13) or 4-part (n=14) proximal humeral fractures. All the patients reported normal shoulder function prior to injury. The range of shoulder motion and muscle power were evalu...
