    Massive and Irreparable Rotator Cuff Tears
    (2020-01-01T00:00:00Z) Bilgin, Emre; Kapıcıoğlu, Mehmet; Bilsel, İsmail Kerem; KAPICIOĞLU, MEHMET; BİLSEL, İSMAIL KEREM
    Rotator cuff (RC) tears are a considerable reason of shoulder disability in both the young and elderly population. Although instrumentation methods and surgical techniques have been improving, the failure rates remain still high after tendon repairs attributed to large tear size, increased age, poor tendon quality and fatty infiltration of the RC muscle.To enhance the healing potential of RC and improve outcomes after repair, various augmentation methods have been introduced over the past two decades. Growth factors, stem cell therapies and scaffolds are the main augmentation approaches. The aim of these procedures is to enhance the healing potential of the repair construct and, simultaneously, help the restoration of the native tendon-to-bone interface.This chapter will focus on scaffold devices and their role in the augmentation of RC repair. The biomechanical properties of the scaffolds, their efficacy, outcomes and complications based on both preclinical and clinical studies are discussed. An overview of the future trends in scaffold augmentation for RC surgery is presented in light of the current literature.

    Biomechanical comparison of humeral nails with different distal locking mechanisms: Insafelock nails versus conventional locking nails.
    (2019-11-01) Erden, T; Kapicioglu, MEHMET; Demirtas, A; Bilsel, K; Akpinar, F; Kuduz, H; KAPICIOĞLU, MEHMET
    Objective: The aim of this study was to compare the biomechanical resistance to rotational and axial forces of a conventional locking nail with a newly designed intramedullary humeral nail developed for humeral shaft fractures with a secure locking mechanism through the distal part of the nail. Methods: InSafeLOCK humeral nail system (group 1, TST, Istanbul, Turkey) and Expert humeral nail system (group 2, DePuy Synthes, Bettlach, Switzerland) of the same size (9 300 mm) were examined. In total, 24 fourth-generation humerus sawbones were used in the experiment. Osteotomy was performed at the humerus shaft, and a defect was created by removing 1 cm of bone. After pre-loading 5000 cycles at a frequency of 2 Hz and a force of 50e250 N for axial loading and 5000 torsion torques between 0.5 Nm and 6.5 Nm at a 2 Hz frequency for torsional loading, the failure load values of each load were recorded. Distal interlocking was performed with an endopin in group 1, while a double cortex screw was used in group 2. Results: All samples successfully passed the cyclic loading. The initial and final stiffness values were similar between the groups after axial loading (p ¼ 0.873 and p ¼ 0.522, respectively). The mean axial failure load values in groups 1 and 2 were 2627 ± 164 N and 7141 ± 1491 N, respectively. A significant difference was found in the axial failure load values (p ¼ 0.004). Significant differences were observed between the initial and final torsional stiffness between the two groups (p ¼ 0.004 and p ¼ 0.004, respectively). No significant difference was found in the failure load values after torsional loading (11791 ± 2055 and 16997 ± 5440 (p ¼ 0.055). Conclusion: These results provide a biomechanical demonstration of the adequate stability of both nails after axial and rotational loading. The reliability of the newly developed InSafeLOCK humeral nail system, which does not require fluoroscopic control and an additional incision for distal locking, supports its use in the clinic.

    Do Techniques for Hill-Sachs Remplissage Matter in Terms of Functional and Radiological Outcomes?
    (2021-06-01T00:00:00Z) Pulatkan, Anil; KAPICIOĞLU, Mehmet; UÇAN, VAHDET; Masai, Mustafa Ngeiywo; Ozdemir, Bulent; Akpinar, Sercan; Bilsel, Kerem; KAPICIOĞLU, MEHMET; UÇAN, VAHDET; BİLSEL, İSMAIL KEREM
    Background: Different techniques are used for the remplissage procedure, including the double-pulley and mattress suture techniques. Both techniques have shown good results; however, it is unclear if one technique is superior. Hypothesis: The remplissage procedure using the double-pulley technique with 2 anchors would have superior functional and radiological outcomes compared with the mattress suture technique with a single anchor. Study Design: Cohort study; Level of evidence, 3. Methods: This study included patients with anterior shoulder instability who were treated using arthroscopic Bankart repair combined with remplissage between 2012 and 2017. A structured questionnaire was used to gather information on the following metrics: Instability Severity Index Score, hyperlaxity, Sugaya index, presence of a Hill-Sachs defect, number of dislocations before surgery, sports participation, radiological measurement of the Hill-Sachs lesion, postoperative range of motion in both shoulders, Rowe score, Walch-Duplay score, American Shoulder and Elbow Surgeons score, and Filling Index Score of Remplissage grade according to magnetic resonance imaging scans at the last follow-up. Results: There were 41 patients included with a mean age of 30 +/- 7 years who underwent the Hill-Sachs remplissage procedure using the double-pulley technique with 2 anchors (n = 21; group DA) or the mattress suture technique with a single anchor (n = 20; group SA). At the final follow-up, there were no significant differences between the groups regarding the Instability Severity Index Score (P = .134), the Sugaya index (P = .538), sports participation (P = .41), the radiological measurement of the Hill-Sachs lesion (P = .803), or the Rowe score (P = .182). However, there were significant differences between the groups in the Walch-Duplay score (P = .012), American Shoulder and Elbow Surgeons score (P = .005), and Filling Index Score of Remplissage grade (P = .015), favoring group DA, as well as differences in external rotation in a neutral position (external rotation loss: 9 degrees +/- 3 degrees [group SA] vs 12 degrees +/- 3 degrees [group DA]; P = .003) and at 90 degrees of abduction (external rotation loss: 8 degrees +/- 3 degrees [group SA] vs 11 degrees +/- 3 degrees [group DA]; P = .006), favoring group SA. Conclusion: In the remplissage procedure, the double-pulley technique provided better filling of the lesion and improvement in functional scores, but external rotation was limited compared with the mattress suture technique.

    Is coracoclavicular ossification a complication or a good prognostic factor after surgical treatment of acromioclavicular joint injury?
    (2022-01-01) Ertogrul R.; Sahin K.; Celik H.; KAPICIOĞLU M.; Ersen A.; Bilsel K.; ŞAHİN, KORAY; KAPICIOĞLU, MEHMET; BİLSEL, İSMAIL KEREM
    © 2022Background: The purpose of this study was to investigate whether heterotopic ossification (HO) in the coracoclavicular (CC) space after surgical treatment of acromioclavicular joint (ACJ) injury is a complication or a sign of good prognosis. Methods: Fifty-nine consecutive patients who underwent CC reconstruction with or without augmentation of the ACJ for acute ACJ injuries were analyzed. Postoperative American Shoulder and Elbow Surgeons (ASES) score, Constant score (CS), subjective shoulder value (SSV), and visual analog scale (VAS) results were evaluated. For radiological evaluation, HO was evaluated, and CC distances were measured. Results: Fifty-one patients (11 women and 40 men; mean age, 36 years [range, 17-68 years]) were evaluated after a mean follow-up of 3 years (range, 2-8 years). The mean ASES score at the follow-up was 82.73 (range, 51.6-100), mean CS was 85 (range, 50-100), mean SSV was 80 (range, 40-100), and mean VAS was 1.9 (range, 0-5). It was observed that the clinical outcomes (ASES, CS, SSV, VAS) of patients who developed ossification in the CC space were better than those who did not although it was not statistically significant. No statistically significant differences were found in the clinical outcomes (ASES, CS, SSV, VAS) between patients who underwent CC reconstruction without augmentation of the ACJ and those who were combined (P > .05). Conclusion: HO in the CC space is a common finding following AC joint fixation injury. We suggest that HO is not a complication and might possibly have positive effects on clinical outcomes.

    Comparison of Single and Double Incision Repair Techniques in Distal Biceps Tendon Rupture
    Objective: The purpose of this study was to compare the complications and functional outcomes of single versus doubleincision repair techniques for the treatment of distal biceps brachii tendon rupture Methods: Between 2012 and 2018, patients with distal biceps brachii tendon rupture who were treated with a single or doubleincision repair technique were included in this retrospective study. Range of motion (ROM) and Mayo elbow performance scores (MEPS) were evaluated. Results: Seventeen patients with a mean age of 45.6±6.4 years (range: 34-58 years) who underwent single (n=9) and double (n=8) incision techniques were included in this study. The mean followup was 33±10.5 months (range: 24-62 months). Preoperative and postoperative ROM and MEPS were similar between two groups (p>0.05). In the single incision repair technique group, 3 patients had lateral antebrachial cutaneous nerve (LACN) palsy and 1 patient was re-operated due to re-rupture. In the double incision repair technique group, 1 patient had posterior interosseous nerve (PIN) palsy and 1 patient had hematoma that did not require surgical drainage. No significant differences were detected in terms of complications (p=0.62). Conclusion: Good functional results were obtained after both single and double incision techniques for the treatment of distal biceps brachii tendon rupture. Both single and double incision techniques were reliable however LACN was at risk in single incision technique and PIN in double incision technique.

    Clinical and anatomical outcomes of isolated coracoclavicular fixation after acromioclavicular joint injury: is it stable enough or is additional horizontal fixation necessary?
    © 2022 The AuthorsBackground: Recently, an emphasis has been put on anatomical reduction of acromioclavicular (AC) joint both in vertical and hortizontal planes for management of AC joint injuries due to persisting horizontal instability. Therefore, an additional AC fixation in horizontal plane has been recommended. However, relation between horizontal AC joint instability and clinical outcomes is still controversial. This study aims to evaluate outcomes of isolated coraco-clavicular fixation using arthroscopic assisted single coraco-clavicular tunnel technique in grade III and V AC joint injuries and to investigate the correlation between anatomical and clinical outcomes. Methods: This study was conducted with 19 patients with grade III or V AC joint injury. Clinical outcomes included postoperative pain intensity and functional outcomes (Constant Score, American Shoulder and Elbow Surgeons, and Subjective Shoulder Value). Radiological evaluations were performed using radiographs and postoperative computed tomography scans. Degree of initial injury and postoperative stability both on axial and coronal planes were evaluated after radiological assessment. Correlations between anatomical and clinical outcomes were investigated using Pearson\"s correlation test. Results: At the final follow-up assessment, the mean pain score was 1.8 ± 1.8, mean American Shoulder and Elbow Surgeons score was 81.0 ± 15.4, mean Subjective Shoulder Value was 81.3 ± 19.6, and mean Constant Score was 86.3 ± 14.8. The mean loosening ratio and AC distance were 43.5 ± 30.6% and 4.3 ± 12.4 mm, respectively. No correlation was observed between postoperative anatomical and clinical outcomes (P > .05). Conclusion: Additional AC fixation on horizontal plane is not a prerequisite for all injuries, there is no significant association between horizontal instability and clinical outcomes and indications of an additional AC fixation needs to be determined.
