Öğe Anterior Inferior Iliac Spine Avulsion Fracture A Series of 5 Cases(Lippincott Williams & Wilkins, 2015) Serbest, Sancar; Tosun, Haci Bayram; Tiftikci, Ugur; Oktas, Birhan; Kesgin, EnginAvulsion fractures of the pelvic apophyses rarely occur in adolescent athletes in the course of sudden strong contraction of muscle attached to growth cartilage. This injury may usually be misdiagnosed for tendon or muscle strain. Patient's history, physical examination, and radiologic studies are important for diagnosis. The literature includes only a few case reports but no case series as yet. The aim of this study was to present the results of 5 cases of anterior inferior iliac spine (AIIS) avulsion fractures treated conservatively. The study included 5 patients (4 male, 1 female, mean age 13.6 years) who underwent conservative treatment for AIIS avulsion fractures and had an adequate follow-up. All patients were admitted to the emergency department and misdiagnosed as muscle strain. Three of them were football player, 1 skier, and 1 fighter. Each patient was treated with immobilization and nonsteroidal anti-inflammatory drugs. At follow-up, all patients showed relief from their pain and mechanical symptoms and regained full range of motion and returned to their previous levels of activity. Diagnosis requires careful attention to the physical examination and imaging. In this series, all pelvic avulsion fractures (100%) were managed successfully with a conservative approach. Good results and return to previous levels of activity can be achieved with conservative treatment.Öğe Comparison of bench-top simulation versus traditional training models in diagnostic arthroscopic skills training(Turkish Joint Diseases Foundation, 2018) Canbeyli, Ibrahim Deniz; Cirpar, Meric; Oktas, Birhan; Keskinkilic, Seyyid IsaObjectives: This study aims to compare the efficacy of existing training models for acquisition of arthroscopic skills and to investigate the most effective training method or combination of methods for residents. Materials and methods: A total of 100 fifth-year students from medical school (40 males, 60 females; mean age 23.7 years; range, 22 to 33 years) volunteered to participate in the study and were randomly divided into five education groups (E1-5): group E1 (trained on bench-top simulator), group E2 (read surgical technique), group E3 (read surgical technique and watched surgical video), group E4 (watched surgical video only), and group E5 (control group). After completion of the pre-training, each student was individually asked to perform an arthroscopy practice. A checklist containing the tasks to be performed w as gig en to students and students were asked to complete the tasks on the checklist in five minutes. Results: In group E1, the mean rate of successful achievement of tasks was significantly higher than other groups in both knee and shoulder arthroscopy models. Rate of each task was statistically similar for groups E2, E3, E4 and E5. In group E1, mean durations for completion of tasks in both arthroscopy models were significantly shorter than other groups. There was no statistically significant difference in terms of gender between those who successfully completed the tasks in both arthroscopy models. Conclusion: A basic arthroscopic bench-top simulator may be a low-cost and effective training method to increase arthroscopic skill levels in resident training compared to traditional methods.Öğe Effect of extracorporeal shock wave therapy on fracture healing in rat femural fractures with intact and excised periosteum(Turkish Joint Diseases Foundation, 2014) Oktas, Birhan; Orhan, Zafer; Erbil, Baris; Degirmenci, Erdem; Ustundag, NilObjectives: The aim of this study is to compare the effect of extracorporeal shock wave therapy (ESWT) on fractures with intact periosteum and excised periosteum. Materials and methods: Thirty-seven Wistar albino rats were randomized into four groups. Osteotomy and intramedullary Kirschner wire fixation were performed on all right femurs under ketamin anesthesia. The first group (n=10) was identified as control group. In the second group (n=10), periosteum located at the osteotomy site was excised circumferentially during surgery. In the third group (n=9), periosteum was left intact and ESWT was applied. In the forth group (n=8), periosteums of all rats were excised and ESWT was applied. All fracture lines were evaluated radiographically each two weeks and histologically at the sixth week. Results were evaluated statistically. Results: In periosteum excised group which represents a model of open fractures with soft tissue defect, ESWT application had a significantly positive histologic effect on bone healing. However, radiological evaluation did not reveal any statistically significant difference between groups with intact and excised periosteums. Conclusion: According to our findings, ESWT can be used to improve fracture healing and prevent pseudoarthrosis in the treatment of open fractures with accompanying soft tissue and periosteum damage. However, further clinical studies are required to include ESWT in routine practice.Öğe The effect of intensive exercise program and kinesiotaping following total knee arthroplasty on functional recovery of patients(Bmc, 2018) Oktas, Birhan; Vergili, OzgeBackground: Total knee arthroplasty (TKA) is a gold standard for terminal term gonarthrosis patients in order to diminish pain, correct deformities, and regain stability. Postoperative functional recovery of patients depends on the current postoperative rehabilitation program to an important extent. The purpose of our study is to compare midterm functional level of gonarthrosis patients who were included in physiotherapy rehabilitation program following TKA with people in similar ages without any surgical indication nor intervention. We have aimed also to compare functionality of people who had additional kinesiotaping (KT) treatment with people who had conservative treatment only after knee arthroplasty. Methods: Functional level and knee functionality of people in study were evaluated at the end of postoperative first month by 6-min walk test and Lysholm knee score respectively. Results: There was no statistical difference between groups with and without TKA in terms of height, weight, body mass index, Lysholm score, and 6-min walk test score (p > 0.05). In patient group with TKA, people with postoperative KT treatment had greater 6-min walk test score for postoperative first month (p = 0.005). Conclusion: TKA is considered a gold standard procedure in order to increase the quality of life and improve functionality of terminal term gonarthrosis patients. It is necessary to immediately control pain and edema of knee and apply intensive rehabilitation program aimed at muscle strengthening around hip and knee in order to increase the success of operation.Öğe Effect of Q-angle, lateral distal tibial angle and hip muscle torques on ankle injury(Ios Press, 2023) Uludag, Mesut; Vergili, Ozge; Kilic, Rabia Tugba; Oktas, Birhan; Yosmaoglu, Hayri BaranBACKGROUND: The ankle sprain is the most common ankle injury. Although the factors that increase the risk of ankle injury are included in the literature, the definitive evidence is controversial. OBJECTIVE: The aim of our study was to examine whether Q-angle, lateral distal tibial angle (LDTA), and hip muscle torque are associated with ankle sprain. METHODS: Thirty-six individuals who underwent an axial X-ray examination of the lower extremity following ankle sprain were included. The Q-angle and LDTA were measured on the axial knee X-rays on both sides. The isometric muscle strength was measured with a digital handheld dynamometer for the quadriceps femoris muscle, the gluteus medius muscle and the gluteus maximus muscle. Muscle torques were calculated by multiplying isometric muscle strength values with the distance to the joint center. RESULTS: Discrimination analysis shows that the gluteus maximus (0.90), gluteus medius (0.49), quadriceps femoris muscle torques (0.34), and lateral distal tibial angle (0.43) were the factors that most contributed to ankle sprain. No significant relationship was found between the Q-angle and ankle sprain (p = 0.603). A strong relationship was found between LDTA, quadriceps femoris, gluteus medius and gluteus maximus muscle torques and ankle sprain (p = 0.014, p < 0.001, p = 0.011, p = 0.002, respectively). CONCLUSIONS: In conclusion, the torques of the proximal muscle may be more related than the Q-angle to lateral ankle sprain injury. Individuals with high LDTA should also be carefully examined for the risk of ankle sprain.Öğe EXPERIMENTAL EVALUATION OF TIGECYCLINE AND TEIKOPLANIN IN THE TREATMENT OF IMPLANT RELATED METHICILLIN RESISTANT STAPHYLOCOCCUS AUREUS (MRSA) OSTEOMYELITIS(Int Journal Pharmaceutical Sciences & Research, 2014) Orhan, Zafer; Degirmenci, Erdem; Oktas, Birhan; Karaduman, Okan; Kir, Gozde; Mulazimoglu, LutfiyeTreatment of implant related MRSA osteomyelitis is a real challenge both for the physician and the patient. We evaluated the comparative efficacy of tigecycline, a novel broad-spectrum glycycline antibiotic and the glycopeptide antibiotic teicoplanin in the treatment of implant related MRSA osteomyelitis in an experimental rat model. Implant related MRSA osteomyelitis was studied in tibial metaphysis of 60 rats. When compared to the control groups, the number of microorganisms was found to be significantly lower in the study groups, but there was no statistically significant difference between tigecycline and teicoplanin respectively. Tigecycline with its good tissue penetration and lower side effects was found to be as effective as teicoplanin in implant related MRSA osteomyelitis, even if the implant is retained. It could be considered as an alternative to glycopeptides because of the efficacy and because of the lower adverse effects in long term usage. Further studies are warranted to suggest a standard medical treatment for implant-related osteomyelitis.Öğe Investigation of new application technique named star taping in patellofemoral pain: a randomized, single-blind, and placebo-controlled study(Taylor & Francis Ltd, 2024) Sahan, Tezel Yildirim; Vergili, Ozge; Oktas, BirhanPurpose: Patellofemoral pain (PFP) is characterized by pain around the patella during functional activity. The purpose of this study was to determine the effects of the new method of applying the patellar Kinesio taping (KT). Materials and methods: Participants with PFP were randomly assigned to a Kinesio star taping (n = 14), placebo taping (n = 12), or control group (n = 13). Knee pain intensity during activity, resting, at night-time and during buckling were measured using the visual analogue scale under both KT, placebo taping, and home exercising before and after six weeks. Oedema, performance, knee function, and muscle strength were assessed with circumferential measurement, the Kujala questionnaire, vertical jumps, a 10-step down test, squat test, triple jump test, respectively, in all groups before and after taping. Results: Decreases were detected in pain in each group (p < 0.05) but there were no differences in pain during activity, and buckling in the three groups before and after taping (p > 0.05). Performances and knee functions showed similar results in all groups before and after taping (p > 0.05). The outcomes of all tapings showed that there were no differences between the groups in terms of oedema (p > 0.05), the knee functions (p > 0.05), and muscles strength on the affected and unaffected sides, there were no significant differences between inter and intra groups (p > 0.05). Conclusions: A 6-week new technique star taping together with home-based exercises have similar effects with placebo taping and home exercise groups on oedema, pain, performance, function in PFP. The effects of star taping technique may be determined in future studies as long- and short-term in different types of injuries.Öğe Mesenchymal stem cells have significant anti-infective effect on methicillin-resistant Staphylococcus epidermidis vascular graft infections(Turkish Joint Diseases Foundation, 2019) Canbeyli, Ibrahim Deniz; Kabalci, Mehmet; Cirpar, Meric; Tiryaki, Meral; Oktas, BirhanObjectives: This study aims to evaluate the effects of mesenchymal stem cell (MSC) implantation on vascular graft infections caused by methicillin-resistant Staphylococcus epidermidis (MRSE) and compare with antibiotic treatment. Materials and methods: Healthy adult 56 Wistar rats (age, over 5 months: weighing. 300-350 g) were divided into eight groups. Group I was defined as the control group and group 2 was defined as the infected control group. Groups 3 and 4 were defined as Dacron grafted and MRSE infected groups. treated with tigecycline and MSCs. respectively. Groups 5 and 6 were performed polytetrafluoroethylene (PTFE) graft and infected with MRSE. These groups were also administered tigecycline and MSC treatment. respectively. Groups 7 and 8 were infected with MRSE without graft administration and were also performed tigecycline and MSC treatment. respectively. Grafts and soft tissue specimens were collected at 13 days postoperatively. Colony counts of pert-graft tissue were performed. All samples were evaluated by enzyme-linked immunosorbent assay (ELISA) for the markers that determine stem cell activity. Results: The overall success of the treatments was assessed by the number of rats with MRSE recurrence, regardless of graft used. The difference between the untreated group 2, tigecycline groups (3. 5 and 7) and MSCs groups (4.6 and 8) were statistically significant. Success of MSC and tigecycline treatments was similar in Dacron. PTFE, and non-grafted groups. There was a resistance of MRSE infection in Dacron groups to MSC and tigecycline treatments. This was considered to be indicative of the susceptibility of the Dacron grafts to infection. However, there was no significant difference between group 2 and Dacron groups in terms of bacterial colonization. ELISA results were significant in three cytokines. Conclusion: Mesenchymal stem cells can be considered as an alternative treatment option on its own or part of a combination therapy for control of vascular graft infections.Öğe Rafting technique without bone grafting in reverse Hill-Sachs lesions(Turkish Joint Diseases Foundation, 2017) Cirpar, Meric; Oktas, Birhan; Daglar, BulentIn this article, we report a case of bilateral posterior shoulder instability, having reverse Hill-Sachs lesions of 25 to 50% of the articular surface on the right side, and of 50% on the left side. The defects were anatomically reconstructed after tuberculum minus osteotomy by elevation of the articular surface and buttressing with raft screws without graft usage. Early rehabilitation with pendulum shoulder exercises was started at third postoperative day. At postoperative sixth week, patient had full range of motion without instability and pain. At postoperative 18th month, the patient had normal physical examination and the constant shoulder score was 86, which was 92.4% of the age-and gender-matched population. Rafting technique without bone grafting may be a treatment alternative with satisfactory clinical results for medium to large sized reverse Hill-Sachs lesions of posterior shoulder instability.Öğe The effect of the platelet-rich plasma on osteogenic potential of the periosteum in an animal bone defect model(Turkish Joint Diseases Foundation, 2021) Oktas, Birhan; Cirpar, Meric; Sanli, Elif; Canbeyli, Ibrahim Deniz; Bozdogan, OnderObjectives: This study aims to investigate whether plasma-rich plasma (PRP) enhances the osteogenic potential of periosteal grafts used to repair bone defects and maintains both histologically and biomechanically more durable bone tissue. Materials and methods: A standard bone defect was formed to the left femurs of 54 Sprague-Dawley rats and three groups were formed. In the first group (n=18), no periosteal repair was done for bone defect. In the second group (n=18), periosteal graft tissue was sutured to cover the defect entirely. In the third group (n=18), before periosteal repair, a 1 mL of PRP fibrin was applied into the bone defect. All femoral specimens were compared histologically at four and six weeks and biomechanically by three-point bending test at six weeks after treatment. Results: In the PRP applied group, healing of the bone defect at four weeks was significantly better than the other groups in terms of histological new bone formation (p<0.05). At six weeks, new bone formation in both of the periosteum preserved groups was superior to the first group (p<0.05, for both). There was no statistically significant difference between the second and third groups at the end of the sixth week in the biomechanical analysis, although both groups were significantly stronger than the first group (p<0.05). Conclusion: Stimulation of the periosteum with PRP application causes early osteogenic differentiation of precursor cells. Although, at biomechanical basis, PRP application does not create any significant difference, in the recovery of the bone defects at very early period, application of PRP may play a role to accelerate fracture and to decrease nonunions.
