Publication Metadata only Use of abdominal negative pressure wound therapy in different indications: a case series(MA HEALTHCARE LTD, 2019) EROL, BÜLENT; Kocaaslan, Fatma Nihal Durmus; Ozkan, Melekber Cavus; Akdeniz, Zeynep; Sacak, Bulent; Erol, Bulent; Yuksel, Mustafa; Celebiler, OzhanNegative pressure wound therapy (NPWT) is a widely used wound management system. Several articles have been published on the advantages and complications of this system. Abdominal dressing negative pressure system (abdominal NPWT) is a newer technology, developed and used in open abdomen cases. The adherence of the sponge to the intra-abdominal organs is prevented by a polyurethane foam. This study presents a number of case series where an abdominal NPWT (ABThera, KCl, US) has been used to treat other vital organs, helping to prevent complications such as organ rupture and fatal bleeding.Publication Metadata only Ekstremite yerleşimli kemik sarkomlarında biyolojik rekonstrüksiyonun orta dönem radyolojik ve fonksiyonel sonuçları(2018-03-18) EROL, BÜLENT; AKGÜLLE, AHMET HAMDİ; EROL B., AKGÜLLE A. H., BAYKAN S. E., ONAY T., BAYSAL Ö.Amaç: Biyolojik rekonstrüksiyon çocuklarda kemik sarkomu rezeksiyonu sonrası kullanılabilir bir seçenektir. Bu çalışmada, çocuklarda kemik rezeksiyonu sonrası biyolojik rekonstrüksiyonun orta-dönem radyolojik ve fonksiyonel sonuçları sunulmuştur. Yöntem: Uzun kemik ve pelviste primer sarkomu olan kırk sekiz hastaya [ortalama yaş 12,5 (4-22 yaş)] geniş cerrahi rezeksiyon ve biyolojik rekonstrüksiyon uygulandı. Kemik defektleri; damarlı fibula grefti (DFG) ile interkalar (32), osteoartiküler (12) rekonstrüksiyonlar ve artrodez(4) şeklinde tedavi edildi. DFG, 19 alt ekstremite rekonstrüksiyonunda yapısal allogreft veya geri kazanılmış kemik ile kombine edildi. Hastalar ortalama 43 ay (25-105 ay) süre ile takip edildiler. Bulgular: 12 ay sonunda hastaların 45’inde (%93,7) greft kaynaması ve greft hipertrofisi gözlendi. 24 ay sonunda DFM ile allogreft/geri kazanılmış otogreft osteointegrasyonu %100 olarak gözlendi. Proksimal humeral osteoartiküler rekonstrüksiyon yapılmış olan 7 çocukta, fibula başı ve gleonid arasındaki morfoloji ve çap uyumsuzluğu devam etti. Proksimal femoral rekonstrüksiyon yapılan 3 hastada fibula başının giderek remodele olduğu gözlendi. Distal radial osteoartiküler rekonstrüksiyon yapılan 2 hastada başlangıçtan itibaren karpal kemiklerle anatomik uyumu olan fibular epifiz eklem yüzünün giderek daha konkavlaştığı görüldü. Boy eşitsizliği osteoartiküler rekonstrüksiyon yapılan hiçbir hastada klinik fonksiyon bozukluğu oluşturmadı. Son takipte ortalama MSTS skorları üst ekstremite rekonstrüksiyonlarında %78 (%66,6-90), alt ekstremite rekonstrüksiyonlarında %82 (%56,6-100) olarak değerlendirildi [Şekil 1B]. Dokuz (%18,75) hastada yeniden cerrahi gerektiren, gecikmiş kaynama (3), implant yetmezliği (2), enfeksiyon (1) ve yara problemi (3) komplikasyonları görüldü. Büyüme plağı/epifiz bölgesinden interkalar rezeksiyon yapılmış olan üç hastada (%6,25) ileride uzatma cerrahisi gerektirebilecek bacak boyu eşitsizliği oluştu. Donör saha komplikasyonları [6 (%12,5); geçici sinir hasarı (3), enfeksiyon (1), yara problemi (2)] konservatif olarak tedavi edildi. 14 (%29) hastada uzak metastaz ve/veya lokal nüks şeklinde hastalığın tekrarladığı görüldü. Defekt büyüklüğü ve DFG uzunluğu ile MSTS skorları ve radyolojik parametreler arasında korelasyon saptanmadı (p>0,05). Çıkarımlar: DFG transferinin başarısı; mikrovasküler tecrübenin yanında, stabil internal fiksasyon, maksimum kemik-kemik birleşimi gibi temel ortopedik prensiplere bağlılık, eklem mobilizasyonu ve ağırlık vermeye ilişkin uygun yaklaşımları gerektirir. Bu seride, büyük kemik defektleri DFG’nin çeşitli şekillerde uygulanması ile tedavi edilmiş ve kalıcı stabilite ile aşamalı olarak iyileşen radyolojik ve fonksiyonel sonuçlar elde edilmiştir. Bu sonuçlar, kemik sarkomlarının tedavisinde biyolojik rekonstrüksiyonun etkinliğini gösteren önceki serileri kuvvetle desteklemektedir.Publication Metadata only Mid-term results of osteoarticular reconstructions of paediatric periarticular bone sarcomas with free fibula head flap(2018-10-13) EROL, BÜLENT; ŞİRİN, EVRİM; AKGÜLLE, AHMET HAMDİ; EROL B., ŞİRİN E., AKGÜLLE A. H., İĞREK S., BAYKAN S. E., TETİK C.Publication Metadata only Comparison of results after surgical repair of acute and chronic ulnar collateral ligament injury of the thumb(ELSEVIER, 2014) EROL, BÜLENT; Basar, H.; Basar, B.; Kaplan, T.; Erol, B.; Tetik, C.This study sought to demonstrate that successful outcomes can be achieved with the new technique presented here for chronic ulnar collateral ligament (UCL) injury of the thumb metacarpophalangeal (MCP) joint, as well as with K-wire pinning for acute UCL injury. We followed 19 patients who suffered an UCL rupture (mean follow-up: 14.26 +/- 4.65 months) and 32 patients who presented with UCL avulsion fracture (mean follow-up: 16.81 +/- 7.54 months). We used a free tendon graft for UCL reconstruction in the UCL rupture group. Both ends of the graft were stabilized with bioabsorbable suture anchors, which were used as biotenodesis interference screws. Closed reduction and K-wire fixation was used in UCL avulsion fracture group. There were no statistically significant differences between operated and contralateral healthy thumb MCP joint in both groups in the grip strength, tip pinch strength, flexion, extension, ulnar deviation, and radial deviation movements at final follow-up. Grip strength, tip pinch strength, ulnar deviation and radial deviation were significantly better in the avulsion group than the rupture group. All patients regained full stability at the MCP joint in avulsion group; 16 patients regained full stability and 3 patients presented with mild laxity (less than 10 degrees laxity) in rupture group. Glickel grading scale used as a functional score was excellent for 30 patients and good for 2 patients in avulsion group; it was excellent for 17 patients and good for 2 patients in rupture group. Our study shows that closed reduction and percutaneous K-wire fixation of acute displaced large UCL avulsion fracture is a simple technique and achieves adequate stability of UCL. For UCL rupture, free tendon reconstruction with bioabsorbable suture anchors provides adequate stability and stable fixation within the tunnels. (C) 2014 Elsevier Masson SAS.

An osteoid osteoma of the toe is very rare and arising in a pedal phalanx may be difficult to diagnose. A 34-year-old male has local swelling and tenderness but there were no hyperemia, temperature increase, or clubbing. There was a 2-month history of antibiotic treatment with suspicion of soft tissue infection in another clinic. The osteoid osteoma was completely excised by curettage and nidus removal with open surgical technique. The patient was followed up for 63 months with annual clinical and radiographic evaluations. There was no relapse of the pain and no residual recurrent tumour. Osteoid osteoma may be difficult to distinguish from chronic infection or myxedema. The patients may be taken for unnecessary treatment. The aim of the treatment for osteoid osteoma is to remove entire nidus by open surgical excision or by percutaneous procedures such as percutaneous radiofrequency and laser ablation. Osteoid osteomas having radiologic and clinical features other than classical presentation of osteoid osteoma are called atypical osteoid osteomas. Atypical localized osteoid osteomas can be easily misdiagnosed and treatment is often complicated.Publication Metadata only Pelvik ve alt ekstemite yerleşimli ewing sarkomlu olgularımızda tedavi sonuçlarımız(2017-04-23) ÖZGEN, ZERRİN; EROL, BÜLENT; TOKUÇ, AYŞE GÜLNUR; EKER, NURŞAH; Özgen Z., Erol B., Tokuç A.

T.Publication Open Access Isolated volar surgical approach for the treatment of perilunate and lunate dislocations(SPRINGER HEIDELBERG, 2014-06) EROL, BÜLENT; Basar, Hakan; Basar, Betul; Erol, Bulent; Tetik, CihangirBackground: Volar and/or dorsal surgical approaches are used for surgical treatment of perilunate and lunate dislocations. There are no accepted approaches for treatment in the literature. We evaluated the functional results of isolated volar surgical approach for the treatment of perilunate and lunate dislocation injuries. Materials and Methods: 9 patients (6 male and 3 female patients average age 34.5 +/- 3.6 years) diagnosed with perilunate or lunate dislocations between January 2000 and January 2009 were involved in the study. The reduction was performed through isolated volar surgical approach and K-wire fixation, fracture stabilization with volar ligament repair was performed. Range of wrist joint motion, fracture healing, carpal stability, grip strength, return to work were evaluated and also direct radiographs were taken routinely at each control. The scapholunate interval and the scapholunate angle were evaluated radiographically. Evaluations of the clinical results were done using the DASH, VAS and Modified Mayo Wrist Scores. Results: The physical rehabilitation was started at 6th week, after the K-wires were removed. The average followup was 18.2 months (range 12-28 months). At the final followup, the average flexion extension arc was 105.0 +/- 9.6 degrees (74.6% of the other side), the average rotation arc was 138.8 +/- 7.8 degrees (81.5% of the other side) and the average radioulnar arc was 56.1 +/- 9.9 degrees (86.4% of the other side). The grip strength was 0.55 bar; 83.2% that the uninjured arm. According to the Mayo Modified Wrist score, the functional result was excellent in five patients and good in four and the average DASH score was 22.8. The scapholunate interval was 2.1 mm and scapholunate angle was 51 degrees. Conclusion: The clinical and radiological results of the isolated volar surgical approach were satisfactory. The dorsal approach was not needed for reduction of dislocations during operations. Our results showed that an isolated volar approach was adequate.Publication Metadata only Tendon-Holding Capacities of Two Newly Designed Implants for Tendon Repair: An Experimental Study on the Flexor Digitorum Profundus Tendon of Sheep(2014) EROL, BÜLENT; Ağır, Ismail; Aytekin, Mahmut Nedim; Başçı, Onur; Caypınar, Barış; Erol, BülentBACKGROUND: Two main factors determine the strength of tendon repair; the tensile strength of material and the gripping capacity of a suture configuration. Different repair techniques and suture materials were developed to increase the strength of repairs but none of techniques and suture materials seem to provide enough tensile strength with safety margins for early active mobilization. In order to overcome this problem tendon suturing implants are being developed. We designed two different suturing implants. The aim of this study was to measure tendon-holding capacities of these implants biomechanically and to compare them with frequently used suture techniques. MATERIALS AND METHODS: In this study we used 64 sheep flexor digitorum profundus tendons. Four study groups were formed and each group had 16 tendons. We applied model 1 and model 2 implant to the first 2 groups and Bunnell and locking-loop techniques to the 3rd and 4th groups respectively by using 5 Ticron sutures. RESULTS: In 13 tendons in group 1 and 15 tendons in group 2 and in all tendons in group 3 and 4, implants and sutures pulled out of the tendon in longitudinal axis at the point of maximum load. The mean tensile strengths were the largest in group 1 and smallest in group 3. CONCLUSION: In conclusion, the new stainless steel tendon suturing implants applied from outside the tendons using steel wires enable a biomechanically stronger repair with less tendon trauma when compared to previously developed tendon repair implants and the traditional suturing techniques.
