If conservative treatment is insufficient for patients with irreparable rotator cuff tears, biodegradable balloon method has yielded favorable outcomes in terms of pain and functionality in comparison with other surgical methods. Moreover, lesser morbidity, short procedure time and absence of postoperative rehabilitation requirement can be considered as advantages of this method.
Epidural fibrosis is a challenging topic in spinal surgery. Numerous clinical and experimental studies have been focused on this issue to clarify problems faced in spinal procedures for the patient as well as the surgeon and find out new methodologies. Dense cytokines and growth factors which are released from inflammatory cells have been suggested to play a major role in the inception and progression of fibrosis. One of the most investigated and important actor in epidural fibrosis is assumed to be the transforming growth factor-1β (TGF-1β) formation. Studies showed that Dexmedetomidine (DEX) downregulates TGF-β pathway with its anti-inflammatory and antioxidant effects. From this point of view, for the first time in the literature we try to observe if there will be an effect of topical DEX administration over epidural fibrosis in a rat model. We hypothesized that DEX might have preventive effects on epidural fibrosis via anti-inflammatory and antioxidant effects. Twenty-four adult male Wistar albino rats were randomly assigned to three groups (Topical DEX, Spongostan, Laminectomy). A total laminectomy was performed at the L3-L5 level and then the ligamentum flavum and epidural fat tissue were cleared away from the surgical site. Histopathological assessment was performed postoperatively after 4 weeks. Our study revealed that topical DEX administration may have effects on reducing epidural fibrosis. Topical DEX administration may be helpful in preventing epidural fibrosis after laminectomy in rats through multiple anti-inflammatory and antioxidant mechanisms as well as through TGF -1β pathway.
Arthroscopic capsulolabral repair is a well-established surgical treatment for traumatic anterior shoulder instability. When there is insufficient labral tissue during arthroscopic primary or revision Bankart repairs, various soft tissue procedures have been recommended. All these procedures aim to reattach glenohumeral ligaments to the glenoid rim and regain the tight anterior structures to prevent re-dislocation or subluxation. Some authors recommend the Latarjet procedure, even in the absence of critical bone loss in this patient group. The labrum increases the depth of the glenoid cavity, thereby, increasing the glenoid track. It behaves like a block for the humeral head. Reconstruction of the labral tissue may strongly contribute to shoulder joint stability when it is totally absent. In this article, we describe a novel labral reconstruction technique (Duru technique) using the long head of the biceps tendon in two patients without an existing labral tissue.
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.
