Aim: To analyze results of proposed reverse transosal suture. Materials: 264 cases (187 patients; 143 men, 44 women, age between 5 to 75 y. o.) of tendon fixation to distal phalanx by proposed technique was accepted in our research, after two stages flexor tendon grafting, in 2008—2019. On 2nd day after surgery - early full amplitude movement rehabilitation protocol (modification of Kleinart technique) was applied. Results: In an interim analysis of 109 patients treatment results, we noted complications associated with a transossal tendon suture to distal phalanx in 7.5 % (8/159) of cases: infectious complication — 1 case, serious nail growth disorders — 1, slight deformation of the nail plate — 5 cases, periodic pain in distant period — 1 case. To avoid complications associated with nail plate disorders, suture technique was modified by displacing the transcutaneous canal to the side of the nail germinal zone without incision on the back of the finger. No deformation of the nail plate was observed after changing of suture technique. Conclusions: flexor digitorum profundus tendon fixation technique minimizes trauma to surrounding tissues. Strong internal fixation of the tendon gives the possibility of early movements. Intermediate material analysis made it possible to change the suture technique to effectively eliminate the most common complications.
Актуальність. Найбільш часта травма плечового суглоба — це вивих плеча. Частота вивихів плеча, за даними літератури, становить 2 % від усіх видів травм населення світу. «Нещаслива тріада» плеча зустрічається в 9–18 % випадків серед передніх вивихів плеча. Мета роботи: створення алгоритму діагностики «нещасливої тріади» плеча для покращання результатів лікування цієї патології. Матеріали та методи. У ДУ «Інститут травматології та ортопедії НАМН України» в період із 2000 по 2018 рік було проведене лікування 492 пацієнтів із вивихом плеча, серед них у 28 була діагностована «нещаслива тріада» плеча. Усі пацієнти були оглянуті клінічно, виконана мануальна оцінка функції дельтоподібного м’яза й чутливості еполетної зони, рентгенографія, комп’ютерна томографія, ультразвукове дослідження (УЗД), магнітно-резонансна томографія (МРТ) і електронейроміографія. Результати. При підозрі на передній вивих плеча мануально оцінюємо функцію дельтоподібного м’яза й чутливість в еполетній зоні. Під загальним знеболюванням виконуємо вправлення вивиху. У подальшому проводимо контроль оцінки функції дельтоподібного м’яза й чутливості еполетної зони. У разі порушення — оцінюємо функцію кисті. Виконуємо УЗД або МРТ плечового суглоба (а за необхідності — МРТ плечового сплетення). Візуалізація на УЗД або МРТ розриву ротаторної манжети плеча в комбінації з порушенням функції дельтоподібного м’яза дає нам підстави до встановлення діагнозу «нещасливої тріади» плеча. Висновки. «Нещаслива тріада» плеча — тяжка травма плечового суглоба, що призводить до тривалої втрати працездатності, а в деяких випадках — і до інвалідизації хворих. Діагностика «нещасливої тріади» плеча пізніше від 8 тижнів із моменту травми значно погіршує результати подальшого лікування цієї патології. Розроблений нами алгоритм діагностики «нещасливої тріади» плеча дозволяє поставити діагноз у ранні терміни після травми, що дає можливість розраховувати на більш повне відновлення функції.
Objective. To determine a role of «wide awake» аnesthesia for improvement of results of tendon–muscular transpositions on the hand. Маterials and methods. During 2016 – 2017 yrs a «wide awake» аnesthesia was applied in 32 patients, suffering consequences of the upper extremity and ageing 16 – 68 years. Median age of the patients have constituted (38.7 ± 14.7) years. Results. The results of a “local awake аnesthesia without placing a tourniquet” while performing a tendon–muscular transpositions and the mobilization operations on the hand were estimated. Conclusion. High efficacy of a «wide awake» аnesthesia in nonvolume function–creating interventions, performed with addition of sliding and active structures and necessitating close intraoperative cooperation with the patient, was proved.
Relevance. The etiology of ruptures of the rotator cuff of the shoulder (RC) is represented by a variety of diseases, including age-related degeneration, low- and high-energy trauma. Most often, a rupture of the RC, combined with trauma, occurs with anterior dislocation of the shoulder – in 56% of patients. The “terrible triad” of the shoulder, which leads to a loss of function and disability in patients, is diagnosed in 9-18% of patients. RC ruptures of <1-1.5 cm throughout the entire thickness of the tendon have a high risk of progression and formation of a massive rupture of the RC. According to various authors, massive ruptures occur in 40% of all RC ruptures. Objective: to evaluate the results of surgical treatment of patients with old and complicated ruptures of the RC. Materials and Methods. From 2016 to 2021, in the SI “Institute of Traumatology and Orthopedics of NAMS of Ukraine”, Department of Microsurgery and Surgery of the Upper Limb, 140 patients with a ruptured RC were treated. The patients underwent: suture of the RC under arthroscopic control, open RC suture, transposition of the latissimus dorsi tendon into the RC defect, implantation of biodegradable InSpace balloon, or implantation of a biomatrix into the RC defect and reverse shoulder arthroplasty. Results. The function was assessed before surgery and in the long-term postoperative period using the Constant-Murley Score. In 5 patients with an implanted balloon, the score increased from 34-38 to 56-61 in 8-12 months. In 7 patients with reinforced biomatrix implantation, the score increased from 34-38 to 65-69 in 9-12 months. In 7 patients with transposition of the latissimus dorsi tendon, the score increased from 35-37 to 68-75 in 9-12 months. In 10 patients with reverse arthroplasty, the score increased from 30-34 to 58-65 in 12-18 months. In 82 patients, after the suture of the RC under arthroscopic control of the shoulder, the score increased from 36-40 to 78-82 in 12-18 months. In 29 patients with an open suture of the RC, the score increased from 34-38 to 68-75 in 12-18 months. Conclusions. Early diagnosis and timely surgical treatment for the pathology of the RC make it possible to obtain the best results in the long-term postoperative period. Massive and old ruptures of the RC require a complete instrumental examination in the preoperative period. The degree of adipose degeneration and rotator arthropathy is of key importance for determining the operative tactics of surgical treatment.
The aim of this study: was determine the force of tension and deformation of axillary nerve in rupture rotator cuff and paresis of deltoid muscle of the shoulder joint. Material and methods: Semi-natural modelling based on the axial scans spiral computed tomography of the intact shoulder joint was performed to determine the degree of traction load on the axillary nerve with distal displacement shoulder head and tendon rupture which paresis of the deltoid muscle. Result: The values of deformations for axillary nerve being at the limit of tissue strength at distal displacement of humeral head of the model by 50 %, progressively increased with increasing distal displacement of humeral head to 100 % of its diameter, reaching values 1.7 times higher than the strength nervous tissue. Conclusion: The progressive changes occurring in the axillary nerve under the action of traction loads, and as a consequence of its ischemia, over time can lead not only to demyelination, but also to the defeat of the axons themselves atrophy of its fibers. In turn, deltoid muscle atrophy increases the traction load on the affected axillary nerve, which forms a vicious circle. The only possible option to "break" the vicious circle is restore the stabilizing structures damaged during the injury, among which one of the most important is the tendons of the rotator cuff of the shoulder. Surgical restoration of the integrity rotator cuff of the shoulder reduces the traction load acting on the axillary nerve, which in turn significantly improves the conditions for reinnervation of the deltoid muscle.
Relevance. Peripheral nerve injuries are potentially disabling lesions, which account for about 2-3% of all injuries. In order to study the clinical manifestations of limb denervation in the early and late stages, we conducted an experimental study. Objective: in the experiment, to study the effect of bone marrow aspirate injection into the target muscles on denervation-reinnervation processes by studying the clinical manifestations of denervation (presence of trophic ulcers, edema, or muscle wasting). Materials and Methods. The experiment was performed on 36 rabbits, which were divided into four groups: a group of pseudo-operated animals, group 1 (neurotomy and sciatic nerve suture), group 2 (on-time injection of bone marrow aspirate), and group 3 (delayed injection of bone marrow aspirate). Detection of hypotrophy or edema of the tibia was performed by determining the percentage of leg circumference of the operated on and intact limbs. Clinical manifestations of limb denervation were recorded during the examination of experimental animals before their euthanasia. Results. When comparing the number of complications in group 1 and group 2, more complications of the denervation process was observed in group 1. At the same time, no difference was found between group 1 and group 3, as well as between group 2 and group 3. When comparing the indicators of hypotrophy, the difference between group 1 and group 2, as well as a significant difference (p<0.05) between group 1 and group 3, with a predominance of hypotrophy in group 2 and group 3 were revealed. Conclusions. The injection of bone marrow aspirate into the target muscles during surgery and in the early stages of reinnervation helped to reduce the clinical manifestations of the denervation process. Delayed administration of bone marrow aspirate to target muscles significantly (p<0.05) helped to reduce edema of denervated target muscles.
The effect of bonemarrow puncture on the sciatic nerve injury repair (experimental study). State Institution "Institute of Traumatology and Orthopedics of the National Academy of Medical Sciences of Ukraine", Kyiv, Ukraine ABSTRACT. Background. Problem of poor recovery efficiency of the damaged peripheral nerve is associated with prolonged nerve fiber regeneration and late reinnervation. Use of autologous bone marrow punctate is suggested for trophic support and stimulation of distal nerve in the path of nerve fiber sprouting. Objective. Investigate the effect of bone marrow aspirate on regeneration of the damaged sciatic nerve with simultaneous and delayed injection. Methods. Complete neurotomy and two end-to-end nerve sutures were applied and modeled on rabbit model. In group 1, only the nerve suture, in group 2, autologous bone marrow punctate was additionally administered, in group 3, punctate was injected 7 weeks afternerve suture. Histological and morphometric methods evaluated nerve regeneration at the level of nerve suture and 5-6 cm at 8, 12 and 18 weeks after surgery. Results. In group 1, 2 and 3 after 8 weeks nerve in the distal segment was recovered at the level of 20.8%, 33.3% and 41.6%; in 12 weeks-41,6%, 72,9% and 75,0%; after 18 weeks-47.9%, 77.1% and 72.9%. Regeneration significantly increased in the period 8-18 weeks in the nerves of group 1, and in groups 2 and 3 recovery was significantly faster, but the density of nerve fibers did not reach the values in the nerves of pseudoperated animals. Conclusions. The use of autologous bone marrow punctate stimulates regeneration of the surgically restored sciatic nerve, increasing density of nerve fiber regeneration and their myelination. Introduction of punctate immediately after the injury stimulates the recovery process to a greater extent than the delayed injection, but the difference is detected only in early stages of recovery.
