Publication Metadata only Pelvic ewing sarcoma: a single center experience(2022-11-01) EROL, BÜLENT; TOKUÇ, AYŞE GÜLNUR; EKER, NURŞAH; Baysal B., EROL B., TOKUÇ A. G. , EKER N., Senay R.Publication Metadata only Staged management of infection with adjustable spacers after megaprosthesis implantation in primary sarcoma patients(2023-03-01) ŞİRİN, EVRİM; AKGÜLLE, AHMET HAMDİ; EROL, BÜLENT; ŞİRİN E., Sofulu O., Baysal O., AKGÜLLE A. H., EROL B.BackgroundWhile periprosthetic joint infection has always been a significant concern for orthopaedic surgeons, the rate of infection is five to ten times higher after tumor prosthesis implantation. With the growing use of mega-implants, the number of these infections has also increased. We aimed to investigate the results of our patients with a primary malignant musculoskeletal tumor, who underwent two-stage revision surgery for an infected mega-prosthesis. We also presented the emerging complicatons and required soft tissue reconstruction procedures.MethodsThe study included 32 primary bone and soft tissue sarcoma patients who underwent a two-stage revision procedure for infection. After a rigorous bone and soft tissue debridement procedure at the first stage, antibiotic-loaded bone cement was wrapped around a cloverleaf type intramedullary nail and inserted into the forming gap. After a minimum of 6 weeks of antibiotic therapy, depending on patients\" clinical signs and serum infection markers, the reimplantation stage was undertaken.ResultsThe mean oncologic follow-up period was 28 months (range 5-96 months). During this period, 11 patients died because of non-infection related causes, 12 patients were alive with their disease, whereas 9 patients were totally free of their oncologic condition. The infection was eradicated in all survivors except one patient, where a high-level transfemoral amputation became necessary.ConclusionPeriprosthetic infection after tumor proshesis implantation in cancer patients can be managed with same principles as conventional arthroplaty procedures, taking care that they are immunocompromised and vulnerable patients and their bone stock loss is significant which makes surgical options more challenging.Publication Open Access Immobilization after pediatric supracondylar humerus fracture surgery: Cast or splint(2022-01-01) ŞİRİN, EVRİM; POLAT, MURAT; ŞAHBAT, YAVUZ; EROL, BÜLENT; AKGÜLLE, AHMET HAMDİ; AKGÜLLE A. H., ŞİRİN E., Baysalo O., POLAT M., Sahbat Y., EROL B.Objective: While surgical treatment is the most accepted treatment method for displaced supracondylar humerus fractures in children, there is little data about immobilization method after surgery. The aim of the study is to determine whether there is any difference in preventing loss of reduction between long-arm cast and long-arm splint following pediatric supracondylar humerus fracture surgery. Patients and Methods: We conducted a retrospective analysis of pediatric patients with supracondylar humerus fractures treated operatively between 2012 and 2019 at a university hospital. According to Skaggs criteria, early postoperative and 3rd-week follow-up X-rays were evaluated for the loss of reduction (LOR). Postoperative immobilization method; splint or cast was compared in the context of LOR. Results: Cast immobilization was found to be superior in preventing LOR in the first three weeks postoperatively (p˂0.05). There was no significant difference for other factors like fracture configuration, patient age and surgical technique. Conclusion: Cast immobilization is superior to splint immobilization in preventing radiologic LOR after pediatric supracondylar humerus fracture surgery however, clinical relevance of this conclusion is yet to be proved.Publication Metadata only Is radiological rotation measurement affected by the fracture pattern in pediatric supracondylar humeral fractures(2023-01-01) ŞAHBAT, YAVUZ; BAYSAL, ÖZGÜR; POLAT, MUHAMMED SAİD; BÜYÜKTOPÇU, ÖMER; EROL, BÜLENT; AKGÜLLE, AHMET HAMDİ; ŞAHBAT Y., BAYSAL Ö., Ağırdil Y., POLAT M. S., BÜYÜKTOPÇU Ö., Shammadli Z., EROL B., AKGÜLLE A. H.Background: In supracondylar humerus fractures (SCHF), the most frequently used method to calculate rotation is the Gordon lateral rotation percentage (GLRP) defined by Gordon et al. However, this technique includes only typical fractures (49%–80% of all fractures) from the Johns Hopkins (J-H) fracture classification system. Purpose: The aim of the study was to investigate (1) is Gordon criteria useful for John Hopkins subgroups of supracondylar fractures and (2) is Gordon criteria affected by internal and external rotation. Material and Methods: This study was designed using four pediatric left humerus bones obtained from the Sawbone© company. For each bone, an osteotomy was made to mimic each of the J-H coronal fracture patterns. The cut bones were placed in a wooden rotation apparatus. The GLRP measurements were taken by five blinded observers. Results: In the repeated measurements of the observers, <20° rotation typical and <30° medial oblique and lateral oblique fracture pattern were measured as within the limits of an acceptable amount of rotation according to the Gordon criteria. However, for high fracture pattern (HFP), ≤30° internal rotation and <60° external rotation were determined to be within the acceptable rotation criteria according to the Gordon criteria. Conclusions: All fracture patterns have different characteristics; however, based on the data of this study, the Gordon criteria can be used safely for typical, medial oblique, and lateral oblique fracture patterns but it is necessary to lower the acceptable rate of 50% for HFP.Publication Open Access Does re-amputation following lower extremity amputation in diabetic or dysvascular patients negatively affect survival(2022-01-01) EROL, BÜLENT; Baysal O., Msangi W. J., Gunar B., EROL B.Objective: We aimed to investigate the characteristics of patients who underwent unilateral amputation due to diabetes and peripheral artery disease, as well as the risk factors that cause re-amputation, and to determine these patients’ survival status and the risk factors for mortality. Patients and Methods: This retrospective study included 133 patients who underwent amputation due to diabetes and peripheral arterial disease between 2012 and 2018. The etiology of amputation, the re-operation rate and time to re-operation following initial amputation, survival status and follow up results were accessed from hospital records. Results: Twenty-eight patients underwent amputation due to peripheral arterial disease, whereas 105 patients had peripheral vasculopathy due to diabetes mellitus. The re-operation rate was 33.8%, and the median period from initial surgery to the second surgery was six-weeks. Sixty-six deceased patients survived with a median of 6 months following initial operation. Conclusion: The most crucial factor causing re-amputation was the non-healing wound problems. Patients with amputation should be followed up carefully for wound problems in the six weeks after surgery. Advanced age, American Society of Anesthesiologist grade 4 patients, associating neurological disease, low albumin level, low lymphocyte count and postoperative intensive care unit requirement were all poor prognostic factors for survival. Re-amputation had no negative effect on survival..Publication Open Access Treatment of locally aggressive benign bone tumors by means of extended intralesional curettage without chemical adjuvants(2022-04-01) EROL, BÜLENT; YENİGÜL A. E., Sofulu O., Erol B.bone tumors treated with extended intralesional curettage without the use of adjuvant in a tertiary orthopedic oncology center. Method: A total of 172 patients treated with surgical curettage and high-speed burrs for the diagnosis of aneurysmal bone cyst, giant cell tumor, osteoblastoma, chondroblastoma, and chondromyxoid fibroma were included in the study. Demographic, radiological, and clinical data of the patients were analyzed. Results: One-hundred seventy two patients (101 (59%) female and 71 (41%) male) with a mean age of 23years (6–84). The mean follow-up period was 48months (18–108). In the study, a total of 8 (4.6%) patients had postoperative complications, 17 (9.9%) patients had recurrence in the postoperative period. Diameter greater than 5 cm was found to be a risk factor for recurrence (p<0.004). The probability of developing complications was found to be significantly higher in patients with recurrence (p<0.001). There was no significant relationship between recurrence and age, tumor type, and tumor stage. Conclusion: Successful treatment results can be obtained with extended surgical curettage, high-speed burr, and cauterization without the use of chemical adjuvants in locally aggressive bone tumors.Publication Open Access Effect of fracture location on rate of conversion to open reduction and clinical outcomes in pediatric Gartland type III supracondylar humerus fractures(2022-02-01) EROL, BÜLENT; Tokyay A., Okay E., Cansu E., Aydemir A. N., EROL B.BACKGROUND: Supracondylar humerus fractures are the most common form of elbow fracture in children and adolescents. At present, treatment planning is based on the Gartland classification. Reduction and percutaneous pinning are done for Gartland type III fractures. In cases where closed reduction is unsuccessful, the procedure is converted to open reduction. However, there is no consensus on which patients are more likely to require conversion to open reduction. The aim of this study was to investigate the effect of fracture location on the rate of conversion to open reduction and clinical outcomes. METHODS: A total of 112 patients who underwent early surgery for Gartland type III supracondylar humerus fracture between August 2011 and August 2017 were evaluated. The patients\" age, sex, facture location, post-operative loss of reduction, and complications were noted. The fractures were classified according to fracture level relative to isthmus (high level) or at/below the isthmus (low level). Closed reduction was initially preferred. Open reduction with percutaneous pinning was performed, when necessary. Flynn\"s criteria were used to evaluate elbow motion after treatment. RESULTS: Mean follow-up time was 39 months (16-62 months). The mean age of the patients was 6.4 +/- 2 years (1.4-12 years). Thirty-nine of the patients were female, 73 were male; 32 fractures were in the dominant arm, 80 were in the non-dominant arm. Ninety of the fractures were classified as high level (proximal) and 22 as low level (distal). Patients with low-level fractures were significantly younger (p0.05). CONCLUSION: The Gartland classification provides important guidance for the treatment of supracondylar humerus fractures, but may have limitations. Our results suggest that revising the classification by incorporating fracture location may be more beneficial for pre-operative planning.Publication Open Access Supracondylar humerus fractures in ınfants and early toddlers; characteristics, clinical and radiological outcomes compared with older children(2022-09-01) AKGÜLLE, AHMET HAMDİ; ŞAHBAT, YAVUZ; EROL, BÜLENT; AKGÜLLE A. H. , Sahbat Y., Baysal O., Kart H., EROL B.Background Supracondylar humerus fractures (SCHF) are rarely seen in the youngest age groups (1-3 years). Although there is no difference in the context of treatment options, it has been shown that younger age groups have different characteristics. Few studies have examined toddlers, which have notably different characteristics. This study is the first to report the characteristics, diagnosis, treatment and functional results of SCHF in infants and early toddlers. Methods A retrospective analysis was made of the data of patients younger than 30 months old, who were operated on in our clinic for SCHF between 2012 and 2020 with at least 2 years of follow-up. Patient demographic and surgical data, and the functional and radiological results were documented. Results Evaluation was made of a total of 52 patients comprising 30 females (58%) and 22 males (42%), with a mean age of 20.75 +/- 5.4 months (range, 6-30 months). The injury was in the right elbow in 24 (46%) patients. The mechanism of injury was a fall from an object at home (table, chair, bed, etc.) in 41 (79%) patients. Patients who fell from a height of more than 4 meters had additional injuries (liver laceration, vertebral fracture, etc.). Only 1 patient had anterior interosseous nerve (AIN) damage before the operation, but the final follow-up neurovascular examinations for all patients were normal. The median follow-up period was 4 years (range, 2-7 years). Flynn outcome scores were (88.5%) excellent and variant Hospital for Special Surgery scores were (82.7%) excellent. Conclusions With appropriate treatment of SCHF, the clinical outcomes in infants and early toddlers are excellent. Using a medial pin to achieve and protect stability in this age group does not increase the risk of iatrogenic ulnar nerve damage. Patients younger than 20 months tend to have more varus malalignment but similar functional results.Publication Open Access Impact of skeletal muscle measurements by chest computed tomography on survival and postoperative complications in patients with soft tissue sarcoma(2022-01-01) ARIKAN, RUKİYE; EROL, BÜLENT; KÖSTEK, OSMAN; BAYOĞLU, İBRAHİM VEDAT; DANE, FAYSAL; YUMUK, PERRAN FULDEN; ÖZGEN, ZERRİN; BUĞDAYCI, ONUR; AKIN TELLİ T., BUĞDAYCI O., Alan O., Sariyar N., Isik S., Arikan R., Yasar A., Majidova N., Celebi A., EROL B., et al.© 2022 Taylor & Francis Group, LLC.This study aims to evaluate whether sarcopenia, measured by chest computed tomography (CT), affects survival outcomes and postoperative complications in soft tissue sarcoma (STS) patients undergoing surgery. In this retrospective study, CT scans of 79 patients were reviewed to measure pectoralis and T12 vertebra muscle area. Both were then adjusted for height (cm2/m2) as pectoralis muscle index (PMI) and T12 vertebra muscle index (TMI). Analyses were performed by dichotomizing muscle indices at gender-specific 50th percentile; PMI and TMI < 50th percentile were defined as low, and ≥50th percentile as high. Overall postsurgical complication rate (PCR) was 16%. Median length of hospital stay (LOHS) was 10 days (3–90). PMI and TMI were significantly lower in women (p = 0.02, p = 0.04). Median body mass index was significantly higher in high PMI and TMI groups (p = 0.01 for both). PCR and LOHS were similar between low and high PMI and TMI groups. Median follow-up was 29 months, 37 patients had recurrence and 23 died. No significant difference was noted between low and high PMI and TMI groups, in terms of disease-free or overall survival. PMI and TMI as measured by chest CT had no impact on survival outcomes or postoperative complications in localized STS.
