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.
This study aims to investigate the effects of hyperbaric oxygen (HBO) therapy and platelet-rich plasma (PRP) on the regeneration of osteochondral defects of the rats, and the synergistic effect of this combined treatment. Materials and methods: This randomized, controlled, and interventional animal study was conducted between May 2014 and August 2014 Osteochondral regeneration was evaluated in four treatment groups (control, PRP, HBO, and HBO+PRP groups) at the 30 th day after iatrogenic injury. Thirty-two female Wistar albino rats (weighing 248-305 g) underwent arthrotomy and osteochondral surgery on left knees. The regenerations of defects were then examined histologically by the modified version of O'Driscoll score. Results: Groups that were treated with either HBO or PRP alone regenerated significantly better than the control group (p=0.01), while no significant difference was found between the HBO-and PRP-treated groups (p>0.05). The defects in group 4 (treated with both HBO and PRP) regenerated significantly better than the control group, the HBO-treated group alone, and the PRP-treated group alone (p=0.01). Conclusion: The results of this study showed a synergistic effect of HBO and PRP on knee cartilage regeneration. However, the possible underlying mechanisms should be the subject of future researches. The aggregation and activation of growth factors released from platelets whose activation is increased in the hyperbaric environment may explain this effect. This may result in a better regeneration than the effect of PRP or HBO alone.
The bucket-handle meniscal tear is a specific type of meniscal injuries which has specific signs on MRI. An attached fragment displaced away from the meniscus with any type of tear causes bucket-handle tear of the meniscus. Magnetic resonance imaging (MRI) is the most commonly used diagnostic tool for meniscal injuries. We present a case of free medial meniscal fragment which mimics the dislocated bucket-handle tear on MRI. The presence of “fragment within the intercondylar notch sign” and “the absence of the bow tie sign” may be an indication of a free meniscal fragment. This should be considered during diagnosis.
Aşil tendon rüptürleri yaygın kas-iskelet sistemi yaralanmalarıdır. Genellikle tek taraflı olarak aktif orta yaş bireylerde meydana gelir. Herhangi bir yatkınlık oluşturan risk faktörü olmadan oluşan spontan rüptürler nadirdir ve bunun da bilateral olması oldukça nadirdir. Biz, herhangi bir risk faktörü olmayan spontan bilateral aşil tendon rüptürü olan 32 yaşındaki erkek olguyu sunuyoruz. Rüptür halter kaldırma sonrası ağırlığa bağlı olarak bilateral gastroknemius kompleksinde meydana gelen aşırı stres ve uzamaya bağlı olarak meydana gelmişti. Klinik tanı konduktan sonra ultrasonografi ile bilateral rüptür gösterildi. Hastaya bilateral cerrahi tamir uygulandı. Rehabilitasyon 6 hafta sonra başlandı. Ameliyattan 8 hafta sonra kısmi, 12 hafta sonra tam yük vererek mobilize olan hasta yaralanma öncesi iş ve sosyal yaşantısına sorunsuz döndü. Bilateral aşil tendon rüptürleri çok nadirdir fakat yüksek farkındalık karşı taraf rüptürlerinin gözden kaçmasını önleyebilecektir.
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.
