    Factors affecting adherence with foot abduction orthosis following Ponseti method
    (Turkish Assoc Orthopaedics Traumatology, 2015) Göksan, Süleyman Bora; Bilgili, Fuat; Bursalı, Ayşegül; Koç, Eylem; Eren, İlker; Faculty Member; School of Medicine; 168021
    Objective: The Ponseti method is an effective protocol for treatment of congenital idiopathic clubfoot. Foot abduction orthosis (FAO) is sometimes necessary to preserve the correction achieved with the serial casting and tenotomy. Patient and family adherence to brace use is a common problem, as nonadherence is directly related to relapse. The aim of this study was to investigate patient and parent characteristics related to relapse. Methods: One hundred and fifty-three children who were treated with Ponseti method (mean age: 44.62 months; range: 16-104 months) and their parents were included in the study. Thirty-one patients experienced relapse at an average follow-up of 32 months (range: 6-84 months) since beginning orthosis use. At the time of follow-up visits, parents were questioned about brace use adherence. Satisfaction with Symptoms Scale in the American Academy of Orthopaedic Surgeons (AAOS) Pediatric Outcomes Data Collection Instrument (PODCI) was used. Results: Difficulties with brace use were encountered in 122 children. Children of parents who were satisfied with the treatment had relapse at an average of 69.13 +/- 2.64 months, and those of parents who were not satisfied at 32.83 +/- 7.51 months. The most important variable was the child's adaptation to the orthosis treatment without an adverse reaction. Additionally, better compliance was found in children with higher-educated parents. Conclusion: Non-compliance with periods of intolerance is very common for children during orthosis treatment. Parents' coping strategies are very important to avoid relapses. It is important to develop strategies to guide parents.

    Reconstruction techniques for mega bone defects
    (Springer Berlin Heidelberg, 2015) Eralp L.; Şen C.; Eren, İlker; Faculty Member; School of Medicine; 168021
    Trauma, tumors, and infections requiring resection leave orthopedic surgeons a problem to deal: bone defects. Bone defect management is a long-lasting topic, and different treatment strategies are suggested. Currently, segment transport techniques are accepted as gold standard for extensive defects. In the last decade, various treatment approaches are popularized. In this chapter, both segment transport and more recent techniques such as vascularized grafting or cage reconstruction are presented. © Springer Berlin Heidelberg 2015. All rights are reserved.

    Background - Impaired shoulder function is the most disabling problem for daily life of Fascioscapulohumeral muscular dystrophy (FSHD) patients. Scapulothoracic arthrodesis can give a high impact to the functionality of patients. Here we report our experience with scapulothoracic arthrodesis and spinal stenosis surgery in FSHD patients. Patients and methods - 32 FSHD patients were collected between 2015-2016. Demographical and clinical features were documented. All the patients were neurologically examined. The Medical Research Council (MRC) and the FSHD evaluation scale was used to assess muscle involvement(1). Scapulothoracic arthrodesis and spinal stenosis surgeries were performed in eligible patients. Results - There were 16 male and 16 female (mean age 34.4 years; range 12-73) patients. 6 shoulders of 4 patients aged between 2132 years underwent scapulothoracic arthrodesis (two bilateral, one left and one right sided). Only one 63 years old female patient with severe hyperlordosis had spinal fusion surgery. All of the patients undergoing these corrective surgeries have better functionality in daily life, as well as superior shoulder elevation. Conclusion - Until the emergence and clinical use of novel therapeutics, surgical interventions are indicated in carefully selected patients with FSHD to improve arm movements, the posture and the quality of life of patients in general. Scapulothorosic arthrodesis is a management with good clinical results and patient satisfaction. In selected cases other corrective orthopedic surgeries like spinal fusion may also be considered.

    Erector spinae plane block for scapulothoracic arthrodesis for facioscapulohumeral dystrophy patients: a case series
    (Lippincott Williams and Wilkins (LWW), 2023) N/A; N/A; Gürkan, Yavuz; Sincer, Yasemin; Manici, Mete; Gedik, Cemil Cihad; Eren, İlker; Demirhan, Mehmet; Faculty Member; Researcher; Faculty Member; Researcher; Faculty Member; Faculty Member; School of Medicine; School of Medicine; School of Medicine; School of Medicine; School of Medicine; School of Medicine; 154129; 349846; 113502; 327612; 168021; 9882
    Facioscapulohumeral dystrophy (FSHD) typically affects the periscapular muscles, resulting in scapular winging. Scapulothoracic arthrodesis (STA) stabilizes the scapula to provide better movement for these patients. Analgesia regimen for FSHD patients who received a single-shot erector spinae plane block (ESPB) and a catheter at the area were retrospectively analyzed in this study. Patients were asked to rate their pain postoperatively and only 5 of 10 patients needed rescue analgesic. No complications occurred. Our experience suggests that continuous ESPB may be helpful for providing analgesia in FSHD patients undergoing STA.

    Objective: The aim of this study was to clinically and radiologically evaluate patients treated with plate osteosynthesis with structural allografts for severely valgus-impacted fractures of the proximal humerus. Methods: The study included 10 patients (average age: 57 years; range: 34 to 77 years) with valgus-impacted Neer Type 4 proximal humerus fractures. Fractures were classified according to the Robinson classification. Patients were called for an up-to-date examination and evaluated radiologically and clinically with Constant and DASH scores. Results: Average follow-up period was 22.5 +/- 12.2 (range: 12 to 50) months. Average DASH score at the final follow-up was 7.6 +/- 4.5 (range: 2.5 to 16.7) and average Constant score was 87.7 +/- 4.4 (range: 83 to 94). None of the cases had early or late head collapse. There was no avascular necrosis. One early screw penetration was observed. Conclusion: Surgical treatment of valgus-impacted proximal humerus fractures achieved successful results. However, the cavity under the humeral head may lead to failure due to mechanical insufficiency. Plate osteosynthesis with structural allografts warrants initial mechanical support until union, thus avoiding complications related to head collapse.

    Introduction to deformity analysis and planning
    (Springer, 2018) N/A; Eren, İlker; Faculty Member; School of Medicine; 168021
    Deformity can be simply described as deviation from normal anatomy. This can be in the form of angulation, translation, rotation or length. The purpose of analysis is to report the magnitude and direction of a deformity or combination of deformities in a patient. To achieve this goal, we should have the standard values of the normal anatomy and a standard radiologic survey to work on. This chapter covers the description and basic components of a deformity and principles to obtain appropriate radiologic imaging for analysis. Details of each deformity component and methods for their correction will be discussed in the following chapters.

    Functional outcomes and complications following scapulothoracic arthrodesis in patients with facioscapulohumeral dystrophy
    (Lippincott Williams and Wilkins (LWW), 2020) Ersen, Ali; Atalar, Ata Can; N/A; Eren, İlker; Birsel, Olgar; Oflazer, Piraye; Demirhan, Mehmet; Faculty Member; Faculty Member; Faculty Member; Faculty Member; School of Medicine; School of Medicine; School of Medicine; School of Medicine; Koç University Hospital; 168021; 202021; N/A; 9882
    Background: Facioscapulohumeral dystrophy (FSHD) is an autosomal-dominant myopathy characterized by facial and shoulder girdle muscle weakness with scapular winging. Scapulothoracic arthrodesis is a successful treatment approach for patients with Methods: We retrospectively reviewed the records of 40 patients (64 shoulders) in whom scapulothoracic arthrodesis was performed. To achieve fusion, multiple multifilament cables were used together with autologous bone and allograft bone. Preoperative and postoperative shoulder elevation and abduction; Disabilities of the Arm, Shoulder and Hand (Quick version, qDASH) scores; and pulmonary function were compared. Recorded complications were classified as pulmonary or scapular. Results: The mean age of the patients at the time of the operation was 25.4 years (range, 15 to 60 years), and the mean duration of follow-up was 71.2 months (range, 12 to 185 months). When the preoperative values were compared with those at the latest follow-up, significant improvement was noted in terms of elevation (from a mean [and standard deviation] of 60.6 degrees +/- 17.2 degrees to 123.7 degrees +/- 26.7 degrees; p < 0.001), abduction (from 52.7 degrees +/- 15.8 degrees to 98.8 degrees +/- 20.3 degrees; p < 0.001), and qDASH scores (from 34.7 +/- 11.4 to 13.3 +/- 13.1; p < 0.001). The overall complication rate was 26.6%. There were 7 pulmonary complications (4 pneumothoraxes, 2 pleural effusions, and 1 major atelectasis), and 5 chest tube placements were required. Ten complications (including 3 rib fractures, 1 brachial plexus palsy, 2 cases of implant irritation, 2 nonunions, 1 delayed union, and 1 scapular fracture) were related to the scapular fixation, and 7 revision procedures were required. Scapulothoracic fusion was achieved in all patients but 1, who had a scapular fracture. Pulmonary function tests were performed for 19 patients, and no difference was observed between preoperative and postoperative results. Conclusions: Scapulothoracic arthrodesis with use of multifilament cables is a successful surgical technique with high fusion rates and low morbidity. Pulmonary complications are common but resolve with careful attention.

    A novel shoulder disability staging system for scapulothoracic arthrodesis in patients with facioscapulohumeral dystrophy
    (Elsevier Masson SAS, 2020) N/A; Eren, İlker; Birsel, Olgar; Çakmak, Özgür Öztop; Aslanger, Ayça Dilruba; Eraslan, Serpil; Kayserili, Hülya; Oflazer, Piraye; Demirhan, Mehmet; Faculty Member; Faculty Member; Faculty Member; Doctor; Researcher; Faculty Member; Faculty Member; Faculty Member; School of Medicine; School of Medicine; School of Medicine; N/A; School of Medicine; School of Medicine; School of Medicine; School of Medicine; Koç University Hospital; 168021; 202021; 299358; N/A; N/A; 7945; N/A; 9882
    Background: Scapulothoracic arthrodesis (STA) is a well-established surgical technique to provide scapular stabilization in patients with facioscapulohumeral dystrophy (FSHD). There is no staging or scoring systems available to guide surgical decision. The aim of this study was to develop a staging system to evaluate the shoulder disability in patients with FSHD to guide surgical decision making and assess its reliability among surgeons. Methods: Fifty-seven shoulders of 29 patients (15 male, 14 female) with an average age of 34.5 years (13–73) were included. Six stages of the disease were defined to create a system consisting of shoulder elevation, deltoid function and scapular winging. Patients were assessed by two independent orthopaedic surgeons who were blind to each other. Statistical analyses included mean and standard deviation for descriptive variables, Pearson's correlation and Cohen's Kappa for inter and intra observer agreement. Results: Measurement of elevation showed excellent correlation in both inter- and intraobserver assessment. There was substantial agreement on deltoid function and moderate agreement on scapular winging. Decision on stage showed excellent agreement on inter observer and substantial agreement on intra observer assessment. Surgical decision using the stage showed excellent agreement on both inter and intra observer assessment. Conclusion: This novel staging system has an excellent inter observer agreement on FSHD patients’ shoulder disability. This would provide surgeons a beneficial tool to define patient groups that would have negatively or positively affected from STA. © 2020 Elsevier Masson SAS
