BACKGROUND: Supracondylar humerus fracture is the most common fracture of the elbow in children. Closed reduction and percutaneous pinning is considered to be the optimal treatment strategy; however, in some instances, open reduction may be necessary. The aim of this retrospective study was to compare clinical and functional results of triceps-splitting posterior versus lateral approach in pediatric supracondylar humerus fracture surgery. METHODS: A total of 38 patients underwent surgery; Group I consisted of 30 patients on whom posterior approach was used, while lateral approach was used on the 8 patients in Group 2. Flynn criteria were used to evaluate cosmetic and clinical results. Fracture healing was assessed with anteroposterior and lateral x-rays. Patients and parents were asked to describe time needed for complete return of full elbow range of motion (ROM) and overall satisfaction. RESULTS: Mean fracture union time was 44.1 days and 46.3 days, and time required to regain complete or near complete elbow ROM was 57.5 days and 55.7 days after splint removal for Group I and Group 2, respectively. Twenty-one of 30 (70%) patients (and parents) in Group I, and 6 of 8 (75%) patients (and parents) in Group 2 were totally satisfied with the results. Twenty-one of 30 (70%) patients in Group 1, and 6 of 8 (75%) patients in Group 2 had excellent cosmetic and functional results according to Flynn outcome criteria. CONCLUSION: In cases of pediatric supracondylar humerus fracture, early closed reduction and percutaneous pinning is preferred; however, when this method is not applicable, triceps-splitting posterior approach is a safe and comparable method to lateral approach with advantages of easier fracture reduction and shorter operating time.

Purpose: Platelet-rich plasma (PRP) includes growth factors and proteins that accelerate and stimulate bone regeneration and tissue recovery. The aim of this study was to evaluate the effects of PRP on fracture healing in terms of biomechanics and histology. Methods: Seventy female rats were included in this experimental study. They were divided into three groups: Group I (no PRP, n = 30), Group II (PRP added, n = 30) and Group III (control, n = 10). The left femurs of the rats in Groups I and II were osteotomized and fixed by K-wires. Although no additional intervention was performed on Group I rats, PRP was applied to the fracture sites of Group II rats. The remaining ten rats were used as the control group of the biomechanical test (Group III). In the fourth week, nine femurs from Group I and ten femurs from Group II, and in the ninth week, nine femurs from each group were removed, and bone recovery was assessed histologically according to Modified Lane-Sandhu histological scoring criteria. Three-point bending test was applied to femurs for biomechanical evaluation in the ninth week. Results: Histological healing was found to be significantly higher in Group II than in Group I ( p < 0.05). Furthermore, biomechanical test results showed that healing quantity and bone strength were significantly better in Group II than in Group I ( p < 0.05). Conclusion: PRP is a widely studied material in the physiology of fracture healing. The results of this study demonstrated the ameliorative biomechanical effects of PRP on fracture healing, in addition to accelerating the histological union of fractures. In the light of these results, PRP could be a viable alternative to accelerate the healing of fractures, late unions or non-unions. Level of evidence: Prospective comparative study, Level II.

Amaç: Bu çalışmamızda erişkin humerus diyafiz kırıklarında plak vida tespiti, kilitli intramedüller çivi ile tespit ve yeni bir tedavi metodu olarak titanyum elastik çivi ile tespit sonucunda kırık kaynama oranlarını, komplikasyon oranlarını ve hastaların fonksiyonel sonuçlarını değerlendirmeyi amaçladık. Elde edilen bulgular ışığında humerus cisim kırıkları için daha basit, kırık biyolojisine daha uygun ve fonksiyonel durumu en üst düzeye çıkarabilecek bir tedavi metodu ortaya konulabilir mi sorusunu araştırmayı planladık.Gereç ve Yöntem: Necmettin Erbakan Üniversitesi Meram Tıp Fakültesi Ortopedi ve Travmatoloji Anabilim Dalında Ocak 2012 ve Ocak 2015 tarihleri arasında tedavi edilen 38 erişkin yaş grubu humerus diyafiz kırığı retrospektif olarak değerlendirildi. Hastaların yaş aralığı, cinsiyete göre dağılımı, kırık etyolojisi,ve hastanede kalış sürelerine yönelik veriler kayıt altına alındı. Hastaların kırık sınıflandırılması AO/OTAsınıflamasına göre yapıldı. En az 6 aylık takibi olan hastalar çalışmaya dahil edildi. Hastaların kontrolleri esnasında direk grafi ile kırık kaynama oranları, varus/valgus dereceleri, ön/arka planda açılanma oranları incelendi. Hastalara fonksiyonel skorlama olarak Omuz, dirsek ve el sakatlık skorlaması (DASH), Mayo Dirsek Skorlaması, UCLA Omuz Skorlaması, Steward-Hunley kriterlerine göre değerlendirme yapıldı. Tüm bu veriler istatistiksel olarak değerlendirilerek 3 tedavi yöntemi arasında fark olup olmadığı değerlendirildi.Bulgular: Gruplar arasında epidemiyolojik olarak anlamlı fark bulunamadı. Kırık etyolojisi, cinsiyet dağılımı ve yaş aralığı literatürle uyumlu bulundu. Hastanede yatış süresinin TEN grubunda anlamlı olarak kısa olduğu bulundu.Kırık kaynama oranlarında ve fonksiyonel skorlamalarda tedavi tiplerine göre anlamlı bir farkı olmadığı anlaşıldı. Varus/valgus ve ön/arka planda açılanma oranlarının TEN ile tedavi edilen grupta bir miktar yüksek olduğu görüldü. Ancak bu oranlar humerus diyafiz kırıkları için kabul edilebilir sınırlar arasında bulundu. Varus/valgusun ve ön/arka plandaki açılanmanın fonksiyonel skorlara etkisi de değerlendirildi ve fonksiyonel durumu etkilemediği analiz edildi.Her üç tedavi tipinde de mükemmel ve iyi sonuçların çoğunlukta olduğu ve gruplarının birbirine istatistiksel olarak üstün olmadığı sonucuna varıldı.Sonuç: Sonuçlarımız ve literatür bilgileri ışığında konservatif tedavinin ekstremiteyi uzun süre hareketsiz bırakması, hastaların yaşam konforunu ve kişisel bakımlarını kısıtlaması, plak vida osteosentezinde yumuşak doku hasarı ve kırık biyolojisinin bozulması, ve kilitli intramedüller çivilerdeki muhtemel omuz problemleri göz önünde bulundurulduğunda titanyum elastik çivinin humerus cisim kırıklarında iyi bir alternatif olabileceğini düşünmekteyiz. Ancak bu tedavi metoduyla alakalı hem bizim serimizin ve takip süremizin az olması nedeniyle hem de literatürde böyle çalışmalar bulunmadığı için yüksek vaka sayılı ve daha uzun süre takipli, randomize kontrollü, prospektif çalışmalara ihtiyaç olduğunu düşünüyoruz.Anahtar Kelimeler: Humerus diyafizer kırıkları, elastik çivi ,TEN, intramedüller çivi, plak vida tespit, erişkin yaş, fonksiyonel sonuçlar, varus/valgus deformite Objectives: The aim of this study is analyze union rates, peroperative complications and funcitonal outcomes of the patients in treatment of humerus shaft fractures in adults with plate-screw fixation, locking intramedullary nail fixation and new treatment method of titanium elastic nail fixation. W aimed to find the treatment of humerus diaphyseal fractures which is minimal easier and optimal for fracture healing biology and which increase the functional outcomes in patients.Materials and Methods: A total of 38 adult patients evaluated in this retrospective study treated for humerus shaft fracture in Necmettin Erbakan Üniversity Meram Medical Faculty Department of Othopedics and Traumathology between January 2012 and January 2015. Ages, sexes, fracture ethiology and hospital duration datas were recorded. Fractures are classified according to AO/OTA classification. The study inlucdes only the patients who has minimal 6 months follow up. Union and varus/valgus and angulation rates were evaluated with X-ray views in clinical visits all of the patients. Funcitonal outcomes were evaluated by Disability of shoulder, elbow and Hand (DASH), Mayo elbow score, UCLA shoulder score and Steward-Hunley criterias. All of these data were analyzed for significant or nonsignificant statistical difference between three treatment methods of humerus shaft fracture.Results: There were no significant difference in epidemological data of three groups. Fracture ethiology, ages, sexes was congruent with literature. Hospital duration time was shorter than the other methods in the group treated with TEN and this was significant. Analysis of union rates and differences in functional outcomes were not significant between three groups. İn TEN group Varus/valgus and angulation rates were higher than the other methods. But this result was in acceptable range for humerus shaft fracture. Also we analysed the correlation of varus/valgus, angulation and funcitonal outcomes. There was no correlation between these deformities and funcitonal outcomes. In all of three groups most of the results were found to be excellent and good (there was no significant difference between groups).Conclusions: According to our results and literature knowledges conservative methods immobilize the extremity, decrease the life quality, and complicate the personal care, plate screw fixation can damage more soft tissue and fracture healing biology than the others, surgical technique of locking intramedullary nail can cause shoulder problems. We think that TEN can be a good alternative for theese fractures. However prospective randomised stıdies with larger number of patients and longer follow-up are needed.Key Words: Humerus diaphyseal fractures , elastic nail, TEN, intrmedullary nail,plate screw fixation, adult age, functional outcomes, varus/valgus deformity 121
