BACKGROUND: Large femoral defects after trauma, femoral non-unions, fractures complicated by osteomyelitis or defects after bone tumour resection present high burden and increased morbidity for patient and are challenging for reconstructive surgeons. Defects larger than 6 cm and smaller defects after failed spongioplasty are suitable for reconstruction using a free, eventually a pedicled vascularised bone flap. The free fibular flap is preferred but an iliac crest free flap or a pedicled medial femoral condyle flap can be also used. These vascularised flaps are ideal for bridging defects of long bones and can be also used as osteocutaneous or osteomuscular flaps for coverage of soft tissue defect if present. The patients and their families were informed that data will be submitted for publication and they gave their written informed consent prior to the submission. The study was approved by the institutional ethic committee. METHODS: We analysed a group of eight patients with large diaphyseal or distal metaphyseal femoral defects. A free fibular flap was used in six patients, a pedicled medial ipsilateral femoral condyle flap was used in two patients and a defect in one patient was reconstructed using an iliac crest free flap. RESULTS: All flaps healed completely in all patients and no fracture of the flap was detected during the study period. In one patient, a locking plate broke and was replaced by a compression plate. At the last check-up all patients were able to step on the reconstructed limb with full weight. DISCUSSION: Although our study comprises a heterogeneous group of cases, they all have been successfully treated by a similar technique, adapted in each case specifically to the needs of the patient. A major limitation parameter of reconstruction by a free vascularised flap is the size of bone defect needed to be reconstructed. In case of a bone defect longer than 6 cm and a concomitant soft tissue disruption, a vascularised double-barrel fibula is the preferred. CONCLUSION: Large femoral defects can be successfully reconstructed with good long-term results using suitable free or pedicled vascularised bone flaps, especially preferring the free fibular flap.

PURPOSE OF THE STUDY Carpometacarpal (CMC) instabilities of the thumb joint occur after injuries or due to joint overload in patients with congenital joint hypermobility. They are often undiagnosed and, if left untreated, are the basis for the development of rhizarthrosis in young individuals. The authors present the results of the Eaton-Littler technique. MATERIAL AND METHODS The authors present a set of 53 CMC joints of patients with an average age of 26.8 years (15-43 years) operated on in the years 2005-2017. Post-traumatic conditions were found in 10 patients and in 43 cases instability was caused by hyperlaxity, also demonstrated in other joints. The operation was performed from the Wagner's modified anteroradial approach. After the operation, a plaster splint was applied for 6 weeks, after which rehabilitation (magnetotherapy, warm-up) began. Patients were evaluated using the VAS (pain at rest and during exercise), DASH score in the work module, and subjective evaluation (no difficulties, difficulties not limiting normal activities, and difficulties limiting normal activities) before surgery and 36 months after surgery. RESULTS During the preoperative assessment, the average VAS value was 5.6 at rest and 8.3 during exercise. During the VAS assessment at rest, the values at 6, 12, 24 and 36 months after surgery were 5.6, 2.9, 0.9, 1, 2 and 1.1. When evaluated in the given intervals under load, the detected values were 4.1, 2, 2.2 and 2.4. The DASH score in the work module was 81.2 before surgery, 46.3 at 6 months, 15.2 at 12 months, 17.3 at 24 months, and 18.4 at 36 months after surgery. In the subjective self-assessment made at 36 months after surgery, 39 patients (74%) assessed their condition as having no difficulties, ten patients (19%) reported difficulties that did not limit normal activities, and four patients (7%) reported difficulties limiting normal activities. DISCUSSION Most authors present the results of their surgeries in patients with post-traumatic joint instability, and they report excellent results at two to six years after surgery. There is a negligible number of studies addressing instabilities in patients with instability caused by hypermobility. When using the conventional method described by the authors in 1973, our results of the evaluation performed at 36 months after surgery are comparable to those reported by other authors. We are well aware of the fact that this is a short-term follow-up and that this method does not prevent developing degenerative changes in the case of long-term follow-up, but reduces clinical difficulties and may delay the development of severe rhizarthrosis in young individuals. CONCLUSIONS CMC instability of the thumb joint is a relatively common disorder, although not all individuals experience clinical difficulties. In the case of difficulties, the instability needs to be diagnosed and treated as this is how the development of early rhizarthrosis in the predisposed individuals can be prevented. Our conclusions suggest a possibility of a surgical solution with good results. Key words: carpometacarpal thumb joint, thumb CMC joint, carpometacarpal thumb instability, joint laxity, rhizarthrosis.

PURPOSE OF THE STUDY It was a prospective, randomised, unblinded study. Effects of the application of platelet-rich fibrin (PRF) on the anatomic anterior ligament reconstruction were examined. MATERIAL AND METHODS A total of 40 patients who underwent a surgery between 2012 and 2014 were enrolled in the study. The patients were randomised into two groups: the group with PRF application (n=20) and the group without PRF application (n=20, control group). The study included 11 women and 29 men, with the mean age at the time of inclusion into the study 29.1 years. Vivostat ® PRF was obtained perioperatively from the patient s blood and applied intraoperatively to the hamstring tendon graft. The ACL graft healing was assessed through magnetic resonance (MRI) at 6 and 12 months postoperatively. The clinical outcomes (the Lysholm score and the IKDC Subjective score, return to pre-injury sport levels, Pivot-shift test, graft failure) as well as standardised laxity measurements using GenouRob arthrometer were performed preoperatively and 12 months after surgery. RESULTS The study was completed by thirty-three (33) patients (17 in the PRF group and 16 in the control group). In two cases, postoperative graft failure was reported (both cases in the control group). No significant differences were found in the process of graft ligamentization evaluated through MRI (p=0.07). No significant difference between the groups was identified with respect to return to pre-injury sport levels (p=0.232), or the Lysholm score and IKDC Subjective score (p=0.259, and p=0.364 respectively). The postoperative knee laxity measurement using Genourob arthrometer did not reveal any significant differences between the PRF group and the control group. DISCUSSION Results similar to those arrived at by our study have recently been published also by other authors worldwide. We can therefore assume that the application of PRF can be of benefit, especially at the early stage of healing. The results still need to be verified on a larger study group, the study design should focus on the development in the early postoperative period. CONCLUSIONS In our study group, no significant difference was observed in the evaluated subjective and objective clinical parameters. Only the parameter regarding the ACL graft failure fell just short of statistical significance, namely to the disadvantage of the group without the PRF application. Key words: anterior cruciate ligament, arthroscopy, anatomic ACL reconstruction, magnetic resonance imaging of the graft, platelet-rich fibrin, graft healing, MRI signal intensity of the graft.

Osteoid osteoma is a primary benign bone tumor with rare intra-articular occurrence. Our case report describes a rare case of a 21-year-old man with long-term severe pain in the right hip region caused by osteoid osteoma managed by arthroscopic excision. The clinical finding of pains and a limited range of motion did not correlate with the normal plain X-ray finding. The osteoid osteoma was suspected based on the CT scan. In literature, several methods of resection of intraarticular osteoid osteoma of the hip are described. Since our department has long specialised in arthroscopic hip surgery and based on the available examinations the tumor appeared to be located within the arthroscopic reach, we decided for arthroscopic resection of the tumor. Our study comprises a detailed description of the entire surgical procedure, the used arthroscopic approaches and the arthroscopic technique of tumor excision. The histological examination of samples taken from the mass confirmed the suspected osteoid osteoma. The success of arthroscopic excision of the tumor was later confirmed also by very positive postoperative recovery when the patient very soon experienced a considerable reduction of pain observed during our five-year follow-up of the patient (Day 13, Week 2 and 6, Year 1, 2 and 5). During the follow-up period, an increase of the Harris Hip Score (13.5 preoperatively vs 76.6/91/94/96/96 postoperatively) and a decrease in VAS (9 preoperatively vs. 3/1/1/1/1) were reported. The follow-up CT and MRI performed at 2 or 5 years after surgery did not show tumor recurrence. The case report includes also illustrations consisting of X-rays, CT and MRI scans before and after surgery as well as multiple scans taken intraoperatively. It has to be emphasized that this is a rare case and an evaluation of a larger group of patients would be necessary to verify the successful outcomes of arthroscopic technique in treatment of the hip joint osteoid osteoma.

Case presentation of 7 years follow up of female patient with wrist arthritis caused by Madelung deformity. As causal treatment remains unknown, the pain reduction by means of selective wrist denervation is one possible option.
PURPOSE OF THE STUDY The failure of arthroplasties and above all the issue of infection and its detection have become an ever more frequently discussed problem. The purpose of our study was to determine the frequency and the type of complications after revision total knee arthroplasties and to compare them with the frequency of complications after primary implantations. MATERIAL AND METHODS In our group of patients followed up in the period from January 2007 to December 2016, in 50 patients the revision surgery was performed for aseptic loosening and in 24 patients for deep infection. In the case of revision surgery for aseptic loosening, in 18 patients original sterilised components were used as a spacer, in 6 patients an articulating cement spacer was applied. Only the complications resulting in the performance of further revision were included in the statistics. A total of 13 patients underwent a primary implantation at another centre. The number of revisions and the reason for implant failure were monitored. The results were compared with the frequency of revision surgeries after primary total knee arthroplasty, of which 2,436 were carried out in the referred to period. RESULTS Of 2,436 primary endoprostheses, altogether 3.1 % failed. In 50 (2.1 %) patients aseptic loosening was reported, 24 patients (1 %) suffered from infection. The median time from primary implantation to revision was 11 years for aseptic loosening, 2 years for infection. The most frequent cause of failure was aseptic loosening. In the group of patients who underwent a revision surgery for aseptic loosening, another revision was necessary in 6 cases (12 %), in the group of patients after the two-stage revision surgery for infection, in 9 cases (37.5 %). The most frequent reason for revision surgery was infection - in both the groups this was the reason for 67 % of revision surgeries. DISCUSSION Our results obtained with respect to primary as well as revision surgeries for aseptic loosening correspond with the results reported by other authors. In the case of two-stage revision implantation, the reported frequency of recurrent infections is the same, the frequency of revision surgeries for aseptic causes is slightly lower in our group. The most frequent causes of revision surgery are also in agreement. In the case of primary implantation, the patients most frequently suffer from aseptic loosening, after revision surgeries another revision surgery is most often performed due to infection. The literature refers to studies suggesting the potential use of original components as a spacer with the same success rate as that achieved with the cement spacer. The original components produced good results in two thirds of two-stage revision implantations, which is why we can agree with these studies. CONCLUSIONS The results clearly show a noticeable increase in the frequency of complications in revision surgeries compared to primary surgeries. In comparison with primary implantations, a subsequent revision after the revision implantation for aseptic loosening was necessary three times more frequently, after the two-stage revision implantation for infection it was ten times more frequently. As the most problematic complication can be considered the infection in case of primary as well as revision interventions. It is obvious that aseptic loosening of the primary implant usually occurs later (the median of 11 years) than the development of deep infection (the median of 2 years). Key words: total knee arthroplasty, revision, failure, complications, aseptic loosening, infection, spacer.

PURPOSE OF THE STUDY Transposition of tibialis posterior muscle ranks among the methods of dorsiflexion restoration in patients with peroneal nerve palsy. Even though this method is commonly used, anatomical variations are still encountered which make us modify the established procedures. The purpose of this study is to evaluate the functional outcomes of operated patients and based on the clinical experience to define by cadaver preparation the anatomical causes preventing the use of the standard transposition technique. MATERIAL AND METHODS The clinical group includes 21 patients (15 men, 6 women) with the mean age of 34.2 years and with common peroneal nerve palsy confirmed by EMG. In 20 patients, transposition of the tendon of the tibialis posterior muscle (MTP) through the interosseous membrane of the leg was performed. In one patient the tendon was transposed ventrally to the distal end of the tibia and fixed in the lateral cuneiform bone due to an extremely narrow space of the interosseous membrane of the leg distally between the lower limb bones. In 18 patients the tendon was fixed by osteosuture to the base of 3rd metatarsal bone, in three patients to the lateral cuneiform bone. The outcomes were evaluated at 6 months after the surgery, when active ankle dorsiflexion (DF) range of motion greater than 5° was considered an excellent outcome, active position at 90° up to DF less than 5° a satisfactory outcome, and any plantigrade position as a poor outcome. The anatomical study included 20 extremities fixed by formalin (10 cadavers, 5 men and 5 women with the mean age of 71.3 years). The length of the individual parts of tibialis posterior muscle was measured and the variations of the muscle attachment were evaluated. The measurement was concluded by a simulation of surgical procedure. RESULTS When evaluating the clinical group, an excellent outcome was reported in 12 patients (57%), a satisfactory outcome in 8 patients (38%) and a poor outcome in one patient (5%). When evaluating the anatomical group, a division of the attaching part of the tendon into three main strips was observed. The thickest middle strip attached to the tuberosity of navicular bone and medial cuneiform bone was reported in all the specimens. The thinner lateral strip (originating from the tendon in 90% of specimens) was attached to the intermediate and lateral cuneiform bone, the cuboid bone, metatarsal bones II-V, and moreover it grows into the origin of the flexor hallucis brevis muscle. The third strip of the tendon attached to the sustentaculum tali, plantar calcaneonavicular ligament and fibrocartilago navicularis was missing in one specimen (5%). When the passing the tendon through the interosseous space between the lower limb bones was simulated in order for the tendon to go in the direction of the planned traction, in two specimens (10%) the pulling through was impossible due to the tendon being thicker than the interosseous space. In two specimens (10%) it was not the tendon, but already the muscular belly which passed through the given space. DISCUSSION In our group, 95% of the functional outcomes were excellent or satisfactory. A poor result was reported in one patient, in whom the EMG examination was not performed as a standard procedure and in whom the muscular strength was insufficient to achieve full dorsiflexion of the ankle. The anatomical study indicates that the narrow space between the lower limb bones can prevent the pulling through of the tendon, which can be addressed intraoperatively by the transposition of the tendon ventrally to tibia. The study reveals that the tendon necessary for transposition can be elongated by the strips of the tendon attached to the sole of the foot. CONCLUSIONS The knowledge of the anatomical conditions may help us better manage potential complications intraoperatively. Key words: tibialis posterior muscle, peroneal nerve palsy, transposition of tibialis posterior muscle, anatomy of tibialis posterior muscle, common fibular nerve palsy.
