Дане дослідження ґрунтується на результатах обстеження та лікування 154пацієнтів, віком від 16 до 75 років (23 хворих жіночої та 131 чоловічої статі) зустановленим діагнозом перелом п'ясної кістки (кісток). Консервативномулікуванню підлягали 70 пацієнтів, хірургічному – 84 пацієнта.Результатом проведеного дослідження стало: вивчення особливостейклінічної картини, даних біомеханічних та експериментальних досліджень, станукістки та п'ясно-фалангових суглобів, а також, розробка та впровадження новихметодик профілактики незадовільних результатів, що дозволять суттєвопокращити якість лікування хворих з переломами 2 – 5 п'ясних кісток. На основісонографічного обстеження п'ясно-фалангових суглобів, вдалося встановитипередумови утворення розгинальних контрактур у пацієнтів з переломамип'ясних кісток. Впровадження комплексного підходу до лікування, системи реабілітації іззастосуванням запропонованих методів дозволяє покращити результатилікування, зокрема підвищити якість життя обраної категорії хворих, скоротитистроки непрацездатності.^UMetacarpal and fingers phalanges fractures make up 10 % of all fractures of thebone of the skeleton and 50 % of them arise as a result of an industrial injury.Fractures of metacarpal bones are found in 30 % of cases of all fractures of the bonesof the hand. The urgency of this problem in recent years is due to a significant number ofcomplications and unsatisfactory results of short tubular bones fractures treatment.They make up 9-25.3 % of patients in orthopedic hospitals. The reason for this trend is often non-known principles of short tubular bones fracture treatment, especially thecorrect fragments reposition and stable fixation, adherence to deadlines fragmentsimmobilization maximum preservation of limb function, and violation of rules ofdifferent osteosynthesis methods and imperfection some hardware.This study is based on the results of the examination and treatment of 154patients (23 female and 131 male) with a diagnosis of metacarpal bone (bones), aged16 to 75 years. For conservative treatment 70 patients were treated, surgical - 84patients.Depending on the type of treatment received, all patients were divided into twoclinical groups. The first group consisted of 70 patients who received conservativetreatment. The second group includes 84 patients who have undergone surgicaltreatment. Patients in both clinical groups were comparable in terms of age, gender,type, and localization of fractures. Patients treated conservatively were divided into 2subgroups: 1) those treated in the classical (long) gypsum band at the position offingernail extension; and 2) those treated in the functional band with the possibility ofmovements in MF joints of the hand. The patients undergoing surgical treatment werealso divided into 2 subgroups: 1) k-wires osteosynthesis and 2) osteosynthesis ofmetacarpal bones fractures by mini plates. The studies included a detailed analysis of complaints and anamnesis. Particular attention was paid to the nature, mechanism of injury and the period from injury to medical treatment. In addition to clinical examination, instrumental, sonographic, Xray and MRI tests were performed. Using personal data (DASH), the patient'sindividual relation to the function of the injured hand was determined, and theobjective indicators of the hand function (AAHS) were investigated.The result of the study was the following: the study of the features of the clinicalpicture, the data of biomechanical and experimental studies, the state of bone andmetacarpal-phalangeal joints, as well as the development and implementation of newmethods for the prevention of poor results that will significantly improve the quality oftreatment in patients with fractures 2-5 metacarpal bones. Based on sonographicexamination of the metacarpal-phalangeal joints, we managed to establish thepreconditions for the establishment of extension contractions in patients with fracturesof metacarpal bones. Real-time modeling of the bone fracture and evaluation of bone-fixationinteraction in the system was performed. An analysis of biomechanical properties ofvarious metal fixators used for metal osteosynthesis of fractures of the metacarpalbones was carried out. A comparative analysis of the biomechanical properties ofvarious fixators was carried out, as well as the metal fixator proposed and developed.Implementation of the developed metal fixator, which will significantly improvethe results of surgical treatment of head and neck fractures of 2 to 5 metacarpal bones,and will make the operative interventions on this subject less traumatic and moreeffective. Development of pathogenetically grounded method of conservative andoperative treatment of patients with fractures of 2 - 5 metacarpal bones.The introduction of a comprehensive approach to treatment, rehabilitationsystems with the application of the proposed methods can improve the results of treatment, in particular, improve the quality of life of the selected category of patients,reduce the disability.
