Pedicle screw instrumentation performed before the age of 5 years does not cause a negative effect on the growth of pedicles, the transverse plane of the vertebral body, or the spinal canal. It can be safely performed in the treatment of deformity in this age group.
According to radiological and histological parameters, PTX appears to improve angiogenesis and healing of segmental cortical bone defects of the radius in a rat model.
The congenital upper lip sinuses are rare and they have previously been reported only in 40 cases. We have presented a case report of congenital midline upper lip sinus in an elderly age. Although the treatment modality is very easy and successful in any cases, the etiology of this rare congenital situation has been obscure and further studies should be done to find out.
Background: EFECE systems are newly defined internal fixation systems, which are suitable for patella fracture fixation. The aim of this study was to compare the fixation strength of EFECE Systems with tension band wiring for transverse patellar fracture simulation on fresh frozen cadaver models. Methods: Quadriceps tendon-patella-patellar tendon (QT-P-PT) complex was prepared from human cadavers. After simulation of a transverse patella fracture, in group 1, 5 patella were fixed with a pair of 1.2 mm EFECE wires and 4 EFECE devices. In group 2, 5 patella were fixed with a pair of 1.2 mm Kirschner wires (K-wire) and a cerclage wire according to the tension band technique. Using a testing device with custom-made jaws, increasing distraction force was applied to these QT-P-PT complexes. Extension of these complexes with the distraction forces was observed. The maximum distraction force and the elongation during maximum force were evaluated. Results: After 5 experiments with the EFECE systems, there was no EFECE wire breakage or EFECE wire-EFECE device catching failure. The median maximum force was 740 N (720-810 N). During maximum distraction force the median extension was 2.5 mm (1.6-2.5 mm). After 5 experiments with the tension band technique, there was no Kwire breakage. The median maximum force was 330 N (240-510 N). During this maximum distraction force the median extension was 3.4 mm (2.2-3.8 mm). Conclusions: Based on the biomechanical advantages, patella fracture treatment with EFECE systems may constitute a reasonable alternative in the treatment of patella fractures.
ÖZAmaç: Bu çalışmada karpometakarpal (KMK) kırıklı çıkık nedeniyle açık veya kapalı redüksiyon ile tedavi edilen hastaların orta dönem klinik takip sonuçları geriye dönük olarak değerlendirilip karşılaştırıldı. Hastalar ve yöntemler: Dördüncü ve beşinci parmak KMK kırıklı çıkık nedeniyle ameliyat edilen 15 hastanın (1 erkek, 14 kadın; ort. yaş 32.5±10.5 yıl; dağılım 18-55 yıl) tıbbi çizelgeleri incelendi. Hastalar uygulanan tedaviye göre kapalı redüksiyon ve perkütan pinleme (KRPP, n= 6) ve açık redüksiyon ve perkütan pinleme (ARPP, n=9) olmak üzere iki gruba ayrıldı. Hastalar tedavi gruplarına kör bir el terapisti tarafından değerlendirildi. Hastalar görsel analog ölçeği (GAÖ), Kol, Omuz ve El Sorunları Hızlı Anketi (Q-DASH) skorları ve yumruk yapma kuvvetine göre karşılaştırıldı. Komplikasyonlar kaydedildi. Bulgular: ARPP grubu ve KRPP grubunun ortalama GAÖ değerleri sırasıyla 2.33±0.50 ve 1.67±0.52 idi. ARPP grubu ve KRPP grubunun ortalama Q-DASH değerleri sırasıyla 13.63±3.21 ve 9.05±2.36 idi. ARPP grubu ve KRPP grubunun ortalama yumruk yapma kuvveti değerleri sırasıyla 65.78±3.70 ve 75.17±6.11 idi. ARPP grubunun ortalama GAÖ ve Q-DASH skorları KRPP grubuna kıyasla istatistiksel olarak anlamlı şekilde daha yüksekti. KRPP grubunun ortalama yumruk yapma kuvveti değeri ARPP grubuna kıyasla istatistiksel olarak anlamlı şekilde daha yüksekti. Sonuç: Dördüncü ve beşinci parmak KMK kırıklı çıkıkların KRPP ile tedavisi yaralanma sonrası erken dönemde istatistiksel olarak daha üstün GAÖ, Q-DASH ve yumruk yapma kuvveti değerleri ile sonuçlanmaktadır.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
