PURPOSE OF THE STUDY The aim of this retrospective study was to assess the subjective evaluation of treatment by patients with respect to their return to work and recreational sport following the fracture of clavicle diaphysis with posttraumatic shortening of 1.5 cm, or more, treated non-operatively and surgically. MATERIAL AND METHODS Our group of patients consisted of 51 patients (14 females, 37 males) aged between 18 and 89 years (average age 46 years). We concentrated on the parameters of sex, age, side of injury, extent of posttraumatic shortening, method of treatment, return to work or recreational sport, DASH score at one year post non-operative or surgical treatment. Patients who sustained a pathological fracture, fractures of the clavicle combined with an injury of the acromioclavicular joint or simultaneous fracture of the humerus or the ribs were excluded from the study. Patients with open fractures or re-fractures were excluded as well. The indication for treatment selection was based on pre-operative discussion of the doctor with the patient and the Informed Consent was signed. The patient was informed about different treatment options. A shorter period of fixation of the arm and post-operative physiotherapy was mentioned in connection with surgical treatment as well as potential surgical complications. A statistical analysis comparing the data in both groups was conducted using the Fisher exact test. The p-value of 0.05 or less was considered as statistically significant. RESULTS The right side was affected 26 times, the left side 25 times. The shortening ranged from 1.5 to 3.7 cm. 24 patients (8 females, 16 males) aged 21 to 89 years (average 54 years) were treated non-operatively. 27 patients (6 females, 21 males) aged 18 to 74 years (average 38 years) underwent surgery. The difference in sex distribution in both groups was not statistically significant (p = 0.5311). According to the Robinson classification, there were 17 patients with type 2A2 fractures, of whom 8 underwent surgery and 9 were treated non-operatively, 19 patients with type 2B1 fractures, of whom 9 underwent surgery and 10 were treated non-operatively, and 15 patients with type 2B2, of whom 10 underwent surgery and 5 were treated non-operatively. The surgically treated patients prevailed in type 2B2 only, but this difference was not statistically significant (p = 0.2350). In the non-operatively treated group, 23 out of 24 patients returned to pre-injury activities in 3 months on average. Ten patients (48%) reported reaching the same function as on the other side. In the DASH score evaluation, 11 patients reached the value of 0-3.3, five patients 3.4-10, six patients 10.1-30.0 and two reached the score of more than 30. In the evaluation of capacity to work, 15 out of 24 patients were able to work, 11 of them without any restrictions or difficulties. In the evaluation of the sport and playing musical instrument module, 9 out of 24 patients did not engage in sports activities or do not play any musical instruments. In the surgically treated group, 26 out of 27 patients returned to pre-injury activities within 6 weeks. 19 (70%) patients reported reaching the same function as on the other side. In the DASH score evaluation, 19 patients reached the value of 0-3.3, two patients 3.4-10, 5 patients 10.1-30.0 and one patient with nonunion 72.5. Comparison of the average values of the DASH score demonstrated slightly better results achieved by surgical treatment (9.03 vs 6.77). When assessing the work module, 24 out of 27 patients returned to work, 20 of them without any restrictions or difficulties. Out of 27 patients, 4 patients were no longer able to engage in sports activities or to play a musical instrument. Of the 23 remaining patients, 18 did not have any problems, 5 suffered from minimal problems. The group of patients treated non-operatively included one case of non-union and the same applies to the surgically treated group. In 3 patients the removal of hardware was performed, 3 patients underwent revision of the surgical wound because of infection. DISCUSSION The recommendation of the weight-bearing of the upper extremity was similar in both groups, 12 weeks post injury/surgery on average. It is clear that sooner return to work or sports activities in the surgically treated group was preferred by younger patients who expected quicker recovery. Younger patients were less patient and more eager to return to work and sports, while the older patients, on the other hand, were more cautious about possible complications of surgery. CONCLUSIONS The results of our study did not identify any correlation between the clavicle shortening and the indication for surgical treatment. Surgical treatment was preferred by younger patients, more frequently by males. The rationale was supported by the perspective of sooner return to work and favourite sports activities. Their decision was not affected by the known risks of surgical treatment. Evaluation of the DASH score at one year after injury/surgery showed similar results. A higher incidence of complications in the surgically treated group did not lead to negative evaluation of the selected treatment modality by the highly motivated group of patients either. Key words: fractures of the clavicle diaphysis, non-operative treatment, surgical treatment, return to work, return to sports activities, functional results at 1 year.

PURPOSE OF THE STUDY The study analyses a cohort of patients with surgically treated ankle fractures who developed complete distal tibiofibular synostoses. It focuses on their occurrence and association with the extent of tibiotalar dislocation of the ankle joint on the trauma X-ray and its relation to the choice of surgery. MATERIAL AND METHODS The cohort of a total of 824 patients with type B and C fractures according to Weber classification was followed up for 9 years. The cohort consisted of 403 (48.9%) men and 421 (51.1%) women. The exclusion criteria included associated talus fractures, calcaneus fractures and fractures of the other bones of the foot. The studied data were obtained retrospectively from medical documentation and by evaluation of trauma X-rays and X-rays obtained during the postoperative checks. The ankle fractures were classified based on the Weber classification and the basic epidemiologic data (age and gender), type of fracture and extent of tibiotalar dislocation of ankle fractures on the trauma X-ray were evaluated. Posttraumatic ankle dislocation was divided into tibiotalar dislocation > 10 mm, tibiotalar dislocation < 10 mm and the group with regular ankle joint. When evaluating the treatment method, the cohort was divided into three groups: Group 1 with one-stage osteosynthesis, Group 2 with temporary K-wire transfixation or external fixation and subsequent secondary conversion to internal osteosynthesis, and Group 3 with definitive transfixation or external fixation of the ankle. The results were statistically evaluated using the Pearson s chi-square test, or the Fisher s exact test for low frequencies. A multivariant logistic regression model was created to identify statistically significant factors contributing to the development of synostosis. The results with the p-value < 0.05 were considered statistically significant. RESULTS In the whole cohort, the synostosis of distal tibiofibular joint was observed in a total of 131 (15.9%) patients. In men it was in 85 (21.1%) cases and in women in 46 (10.9%) cases, which was statistically significant (p < 0.0001). There was a statistically significant difference (p = 0.0020) between the mean age in the group of patients with synostosis (54.4 years) and the mean age in the group of patients without synostosis (49.1 years). Complete distal tibiofibular synostoses were found in 78 (12.7%) fractures classified as type B according to the Weber classification and in 53 (25.5%) type C fractures. When taking into account the gender, synostoses occurred more frequently in men in both types of fractures classified based on the Weber classification, only in type C fractures no statistical significance was established (p = 0.3026). Various size of posttraumatic tibiotalar dislocation was present in both types of fractures. The group with less severe type B ankle fractures showed a statistically significant dominance of synostosis development in cases with large tibiotalar dislocation of more than 10 mm (p<0.0001). In the group with type C fractures different results were obtained. The highest frequency of cases with synostosis was reported in the group with dislocation smaller than 10 mm (p = 0.0698). In the entire cohort, 615 (74.6%) one-stage osteosyntheses were performed and synostoses developed in 77 (12.5%) cases. In 165 (20.0%) patients, transfixation with K-wires or external fixation with subsequent conversion to secondary osteosynthesis were used and synostoses were identified in 50 (30.3%) cases (p < 0.0001). The open fractures showed an insignificantly smaller number of synostoses than the closed fractures (p = 0.5902). DISCUSSION Posttraumatic distal tibiofibular synostoses have varied morphology. A number of studies confirmed that they do not affect much the functional status of the ankle, even despite their extensive finding in the area of syndesmosis is evident on the Xray. Etiologically, a certain role in their development is reported to be played by posttraumatic hematoma in case of damage to deep soft and bony structures of the ankle. CONCLUSIONS A higher occurrence of synostoses was observed in male population, older age patients and also in type C fractures according to the Weber classification. Larger tibiotalar dislocation showed statistical significance in the development of synostoses in type B fractures according to the Weber classification, whereas in type C fractures it was not the main factor contributing to the development of synostosis. In cases where one-staged osteosynthesis was performed, the occurrence of synostoses was statistically significantly lower than in secondary osteosynthesis after temporary stabilisation. Key words: ankle fracture, distal tibiofibular synostosis, ankle joint dislocation, Weber classification, acute surgery, delayed surgery.

PURPOSE OF THE STUDY Lumbar spinal stenosis (LSS) is a serious and fairly frequent disorder with prevalence increasing with age which often results in a disability. The surgical procedures are often very risky due to the greater age of patients with severe stenosis and their comorbidities. The study aimed to assess the functional outcomes and complications in patients who underwent surgical treatment for LSS at one year postoperatively and to identify the differences in the functional outcomes, if any, in dependence on the number of operated segments. MATERIAL AND METHODS It was a prospective study which included 33 patients who underwent surgery at the authors department from 1 November 2015 to 1 October 2016 for LSS, the mean age of patients was 69.5 (43-83) years. The surgery was indicated based on the clinical examination, radiography and MR imaging and consisted in posterior decompression with or without stabilisation and fusion. Pre- and post-operatively, a neurological examination and evaluation of patient difficulties were performed by: VAS - particularly for low back pain (VAS-LB) and lower limb pain (VAS-LL), Oswestry Disability Index (ODI) and Swiss Spinal Stenosis Questionnaire (SSSQ). The evaluation was done at a half year and one year after the surgery. The authors made comparisons in dependence on the number of treated segments (1-2, 3-5 and Th-S stabilisation). RESULTS A significant improvement of all the followed-up parameters was reported at one year postoperatively. At one year after the surgery, the VAS-LB score showed a decrease by 2.39 (p = 0.001), the VAS-LL by 3.26 (p < 0.001), while a decrease by 2 or more points is considered clinically significant. When evaluating the SSSQ questionnaire, a decrease in subjective difficulties (SSSQ-S) was by 0.89 (p < 0.001), in physical function (SSSQ-F) by 0.87 (p < 0.001). In this questionnaire, the satisfaction rate with the surgery was 2 - i.e. somewhat satisfied. Altogether 76% of patients were very or somewhat satisfied, no one was very dissatisfied. When evaluating the ODI, an improvement by 20.6% (p < 0.001) was reported. The authors identified neither any significant differences in the outcomes at a one-year follow-up in dependence on the length of stabilisation, nor any significant differences between the six-months and one-year follow-up. Intraoperative complications occurred in 18%, early postoperative complications in 6% of patients. The ASD developed in 9% within one year. DISCUSSION The authors confirmed a significant improvement of the followed-up parameters (VAS-LB, VAS-LL, SSSQ, ODI) which corresponds with recent literature. The decrease in VAS and ODI in the authors study is more marked than the outcomes stated in literature. The authors outcomes clearly show that there is no correlation with the length of stabilisation and the number of decompressed segments. Conversely, the rate of complications was higher in this group than the rates stated in literature, but majority of complications had no consequences for the patients. CONCLUSIONS In the group of patients with a one-year follow-up the authors confirmed that surgical procedures will result in reduced subjective difficulties of patients, reduced pain and improvement of physical function. A significant improvement of all the followed-up parameters was reported. The authors did not confirm the correlation between the postoperative improvement and the number of treated segments. Key words:lumbar spinal stenosis, quality of life, post-operative outcomes, complications.

PURPOSE OF THE STUDY Ankle fractures are characterised by a high variability of damage to bone and ligament structures which leads to diverse clinical conditions. This study aims to analyse a group of patients with surgically treated ankle fractures, with a focus on evaluating the outcomes of treatment of ankle joint medial structure injuries (medial malleolar fracture, ligament lesions). MATERIAL AND METHODS The analysed group included 186 patients (102 men and 84 women), in whom an ankle fracture surgery was performed in 2015 and 2016. The outcomes of the treatment were evaluated in 111 patients with type B and type C fractures, who underwent a follow-up examination at one year after the surgery consisting in subjective and objective assessment of the condition and an ankle radiograph. The obtained outcomes were processed using the techniques of descriptive statistics and subsequently evaluated through the Pearson´s chi-square test at 5% significance level, or the Fisher´s exact test for low frequencies. RESULTS The mean age of patients in the group was 48.6 years, while it was lower in men than in women (42.8 years compared to 53.9 years). According to Weber classification, 1 % of fractures were classified as a type A fracture, 68 % as a type B, 27 % as a type C. The group of isolated medial malleolar fractures represented 4 % of cases. The medial side of the ankle joint more frequently suffered a ligament lesion (56 %) than a medial malleolar fracture (44 %). The mean age of the patients with a medial malleolar fracture was 51.9 years, whereas the mean age of the patients with a ligament lesion on the medial side of the ankle was 44.2 years. When evaluating the outcomes using the OMA score at one year postoperatively, a statistically significant difference was found (p = 0.002) between the patients with a medial malleolar fracture (OMA 79.9) and the patients with a ligament lesion at the medial side of the ankle joint (OMA 91.2). DISCUSSION The aim of the study was to add more information on medial structures of ankle joint that are of major importance for ensuring stability of ankle fractures. In agreement with the literature, when managing the ankle fractures with an injury suffered on the medial side there is obviously a more uniform approach in cases with medial malleolar fractures. The situation is different in case of the deltoid ligament lesion, when historically there is a certain level of non-uniformity in indications for revision surgeries and treatment of the injured ligament structures. In our group, in the case of ligament lesion on the medial side of the ankle joint an emphasis is put on the fluoroscopy control of the symmetry of tibiotalar joint space before the beginning of the surgery and also after the fibular fracture stabilisation. The revision surgery was indicated in cases where asymmetry of ankle fork was found. The patients considered the treatment outcome better in cases with a ligament lesion than in cases with a medial malleolar fracture. CONCLUSIONS Proper treatment of medial structures of the ankle joint is important for ensuring the stability of ankle fractures. The patients with type B fractures reported better results at one year postoperatively compared to the patients with type C fracture according to the Weber classification. A statistically significantly better results after the ankle fracture surgery were achieved in patients with the presence of a medial ligament lesion compared to the patients with a medial malleolar fracture. Key words:ankle fracture, injury of medial structures, epidemiology, outcomes of treatment.

The aim was to construct a composite structure for bone tissue substitute on the basis of a degradable composite of an organic nanofiber carrier and an inorganic matrix in 3D, and to achieve subsequent colonisation by differentiated human mesenchymal stem cells (hMSC) towards osteocytes. We developed an active bone tissue substitute using nanofiber technology for a polycaprolactone (PCL) scaffold with the addition of hydroxyapatite and the colonisation of both components with hMSC with the ability of differentiation towards osteocytes. The constructed composition included the components necessary for bone healing (inorganic and cellular) and it also forms a spatially-oriented 3D structure. We used polycaprolactone Mw 70,000 with electrostatic spinning for the formation of nanofibers using a modified NanospiderTM method. For the inorganic component we used orthophosphate-calcium silicate with a crystal size of 1-2 mm which the nanofiber membrane was coated with. Both components were connected together with a tissue adhesive based of fibrin glue. Cultivated hMSC cells at a concentration of 1.2 × 104/cm2 were multiplied in vitro and then cultivated in the expansion medium. HMSC overgrew both the PCL membrane and the Si-CaP crystals. After colonisation with cultivated cells, this composite 3D structure can serve as a three-dimensional bone tissue replacement.
