    Comparison Of Efficacy Of Oral Versus Intra-Articular Corticosteroid Application In The Treatment Of Frozen Shoulder: An Experimental Study In Rats
    (2022) Cinar, Bekir Murat; Battal, Vahit Erdal; Bal, Nebil; Guler, Umit Ozgur; Beyaz, Salih; 35234132
    Objective: The aim of this study was to compare clinical and histopathological effects of oral versus intraarticular corticosteroid application in a rat model of frozen shoulder. Methods: In this study, eighty adult Sprague-Dawley rats were used. The animals were divided into 5 equal groups. The frozen shoulder model was created by immobilizing animals' shoulders with internal fixation with sutures for 8 weeks. At the 8th week, sham(n: 16) and control (n: 16) groups were sacrificed to collect data for healthy and affected shoulders. Also, at the 8th week, 50 mg/kg methylprednisolone was started for the oral treatment group, and a single dose of 0.5mg/kg triamcinolone acetonide was injected for the intraarticular treatment group. The effect of additional steroid treatment was expected for 2 weeks, then all remaining treatment and natural course groups were sacrificed on the 10th week. Results: After sacrification, specimens taken as "en bloc" scapulothoracic disarticulation were randomly divided into two groups for a range of motion measurement and histopathological examination. The control (frozen shoulder model) group's shoulder range of motion in all directions was lower than the sham (healthy) group (P < 0.01). Natural course and intraarticular steroid groups, compared to the frozen shoulder model showed a significant increase in the direction of abduction (P < 0.05). Also, it was found for treatment groups that in all directions the range of motion was not as good as the healthy values (P < 0.01). The intraarticular treatment group showed higher degrees of abduction compared to the natural course and oral steroid treatment groups (P < 0.01). Oral steroid treatment group's range of motion was not significantly better than the disease model and had no superiority to the natural course group (P > 0.05). Histopathologically, no statistically significant difference was observed between the groups for signs of frozen shoulder which was found in the immobilized group (P > 0.05). Histopathologically, immobilization was found to cause thickening of the capsule that cannot be resolved by treatment. (P < 0.05). Conclusion: In frozen shoulder disease, intraarticular steroid injection seems to be superior in increasing the range of motion than oral steroid treatment.

    A Comparative Study On Use of Two Versus Three Double-Loaded Suture Anchors in Arthroscopic Bankart Repair
    (2021) Ozdemir, Bulent; Akpinar, Sercan; Cinar, Bekir Murat; 0000-0002-7906-5039; 33463425; AAL-4474-2021
    Objectives: This study aims to compare clinical results of repair using two versus three double-loaded suture anchors in arthroscopic Bankart repair. Patients and methods: Between July 2012 and December 2017, a total of 40 patients (38 males, 2 females; mean age: 31.68.1; range: 17 to 47 years) who underwent Bankart arthroscopic surgery and were followed for minimum two years were retrospectively analyzed. Group 1 (n=17) underwent arthroscopic Bankart repair with two double-loaded suture anchors, while Group 2 (n=23) underwent repair with three double-loaded suture anchors. Clinical outcomes of the patients and recurrences were compared. Results: At the final postoperative follow-up, a significant improvement was observed in the functional outcomes in all patients. No statistically significant difference was found (p>0.05) in the mean clinical scores of the Constant Shoulder Score between Group 1 (94.2 +/- 7.8) and Group 2 (95.4 +/- 4.1). There was no significant difference in the mean Rowe scores (Group 1: 95.6 +/- 4.6 vs. Group 2: 96.3 +/- 3.8, respectively) and external rotation loss (at neutral Group 1: 1.9 degrees vs. Group 2: 2.2 degrees, respectively). Three of our patients had recurrent dislocation during a major traumatic event (n=2 in Group 1 and n=1 in Group 2). Conclusion: Our study results suggest that stability is not correlated with the use of either two versus three double-loaded suture anchors in arthroscopic Bankart repairs.

    Supramalleolar osteotomy with a hexapod type external fixator for the treatment of ankle joint three planar deformity: Case report
    (2020) Cinar, Bekir Murat; Guler, Umit Ozgur; 0000-0002-5375-635X; 0000-0002-7906-5039; 32584739; AAJ-4844-2021; AAL-4474-2021
    The varus ankle deformity can lead to osteoarthritis; therefore, numerous supramalleolar tibia osteotomy techniques are described to correct this deformity. Many of these techniques are more suitable for uniplanar ankle deformity. Particularly, if there are multiplane ankle deformities, the use of the six-axis deformity correction system may be successful in solving the problems which may occur during the correction. In this article, we report two cases of three plane deformities of ankle joint due to trauma sequelae, which were treated with supramalleolar osteotomy using a hexapod fixator which is called the Smart Correction Frame (R).
