r, distal femur or proximal humerus, which is of equal quality. The other regions, proximal tibia and ulna, contain only minimum concentration of red bone marrow. CONCLUSIONS The experimental study comparing the concentration of red bone marrow in grafts harvested using a minimally invasive procedure from the region of greater trochanter, distal femur and proximal humerus concluded that these samples are comparable with the grafts from the iliac wing. The grafts harvested from proximal tibia and proximal ulna show only negligible concentration of red bone marrow and their use in clinical practice is disputable. The benefits of our experimental study for treatment shall be further evaluated in a clinical study.

The correlation with postoperative neurologic deficit was evaluated too. MATERIAL AND METHODS Between January 2007 and January 2018, a group of 113 patients was evaluated in the study who underwent spine surgery using intraoperative neurophysiological monitoring (IONM) focusing on transcranial motor evoked potential (tc-MEP) monitoring. The average age of the patients was 30 years. Tc-MEPs were recorded bilaterally from tibialis anterior muscle and the abductor hallucis muscle in 88 patients without neurological deficit and in 25 patients with neurological deficit. The peak latency of waveform amplitude was defined as the period from stimulation until the waveform amplitude reached its peak. The correlation with postoperative neurological deficit was examined separately for latency delays of 5% and 10% or more and in cith the decrease of waveform amplitude. Another study found similarities in the decrease of amplitude of 70 % or more from baseline and the delay in amplitude latency of 10% or more from baseline; with 86% sensitivity, 98% specificity, 2% FPR and 86% PPV (1). CONCLUSIONS In conclusion, we investigated the efficacy of a change of peak latency delay of waveform amplitude in tc-MEP monitoring. The utilizing of the peak latency delay of waveform amplitude value resulted in high sensitivity up to 100 % and allows reduction of the FPR and an increase of the PPV. Further studies should set the alarm criteria more precisely for the waveform amplitude latency peak delay to achieve more effective spinal cord tc-MEP monitoring. Our concept of findings supports the neurophysiological monitoring findings in other studies.

The aim of this study was to compare the "rotational" (more than one surgeon) and "full-time single surgeon" use of the orthopedic theater. MATERIAL AND METHODS We retrospectively evaluated patients who underwent orthopedic surgery in 2016 in different theaters. A total of 604 of 1973 patients were excluded from the study, and 1369 patients were analyzed. The follow-up period was 1 year. While evaluating the cases, the duration and order of each case, the total operation time on the table, the number of surgeons, the total number of cases, the number of residents, and the experiences of the surgeons were investigated, and the effects of these parameters on the complication rates were analyzed. The Dindo-Clavien system was used to classify the complications. RESULTS When comparing the methods, the complication rate of the full-time single-surgeon method (12.9%) was less than that of the rotational method (21.7%) (p 0.022). A higher rate of complications (8.5%) was observed in operations with a duration of 115 minutes or more compared to other operations (p less then 0.001). A higher complication rate (23.7%) was observed in cases lasting more than 345 minutes (p = 0.002). CONCLUSIONS According to our study, full-time use of the orthopedic theater by a single surgeon was found to be safer than rotational use. In addition, the duration of surgeries lasting longer than 115 minutes or longer than 345 minutes during the day increased the rate of surgical complications. Key words patient safety, surgical planning, operation time, operation order, orthopedic complication.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 monitorning 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. Selleck Aminoguanidine hydrochloride 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 The purpose of this study is to evaluate the results of chronic tendinous mallet finger repair with all soft suture anchors. MATERIAL AND METHODS In this retrospective study we evaluated 14 patients. Data included age, side of surgery, the degree of extensor lag, the ratio of the damaged articular surface, postoperative recovery period and time to return to work. We recorded extensor lag and Crawford scores of all patients at the last follow-up. RESULTS Mean follow-up period was 22.07 months. The preoperative and postoperative extensor lags were 27.2 (15-35) and 3 (0-19), respectively. Crawford scores of patients were moderate in 1 patient, fair in 2 patients and excellent in 10 patients. We observed only one skin complication in the postoperative period. CONCLUSIONS All-soft suture anchors have high patient satisfaction rates and functional results. Thus, they could be used in the treatment of patients with chronic tendinous mallet finger. The low complication rate is a major advantage. Key words tendinous mallet finger, hand surgery, all-soft anchor.
