Peripheral nerve injury causes severe loss of motor and sensory functions, consequently increasing morbidity in affected patients. An autogenous graft is considered the current gold standard for reconstructing defects recovering lost neurological functions; however, there are certain limitations to this method, such as limited donor supply. With advances regenerative medicine, recent research has focused on fabrication tissue-engineered grafts promising alternatives grafts. In study, we...
Abstract The need for the development of soft materials capable stably adhering to nerve tissues without any suturing followed by additional damages is at fore a time when success in postoperative recovery depends largely on surgical experience and/or specialized microsuturing skills surgeon. Despite fully recognizing such prerequisite conditions, designing with robust adhesion wet nerves as well acute/chronic anti‐inflammation remains be resolved. Herein, sticky and strain‐gradient...
Longitudinally oriented, 3D printed collagen hydrogel-grafted elastic nerve guidance conduits to promote regeneration in peripheral defects.
Objectives With the increasing popularity of searches for medical information on YouTube, availability videos concerning carpal tunnel syndrome (CTS) is increasing. This study aimed to evaluate quality and reliability YouTube CTS. Setting participants No were included. Primary secondary outcome measures We searched 1 April 2021 using keywords “carpal syndrome” release” evaluated first 55 retrieved videos. summarised video characteristics including Video Power Index (VPI), which was designed...
A survey for aflatoxin B(1) (AFB(1)) was conducted on 88 food-grade rice samples randomly collected during July and August 2002 in Seoul, Korea. The presence of AFB(1) determined by enzyme-linked immunosorbent assay, the positive from assay were confirmed using high-performance liquid chromatography. Besides this, surveying data literature published since 1997, intake food Korea calculated compared with provisional maximum tolerable daily intakes. Naturally occurring found 5/88 (6%) an...
The early detection of osteoarthritis (OA) is currently a key challenge in the field rheumatology. Biochemical studies OA have indicated that matrix metalloproteinase-13 (MMP-13) plays central role cartilage degradation. In this study, we describe potential use dark-quenched fluorogenic MMP-13 probe to image both vitro and rat models. imaging technique involved using peptide substrate, near-infrared (NIR) dye, NIR dark quencher. results from study demonstrate allows for visual OA-induced...
Trigger finger is frequently treated with tendon sheath injections. This cadaveric study evaluated the accuracy and safety of blind sonographically guided To our knowledge, a that precisely mapped locations material injected into has not been reported previously.A total 40 fingers (excluding thumbs) 5 fresh cadavers were used. Methylene blue dye was flexor using either or injection technique (20 for each technique). The location then determined via dissection.Dye observed only in (ie,...
The joint angle during gait is an important indicator, such as injury risk index, rehabilitation status evaluation, etc. To analyze gait, inertial measurement unit (IMU) sensors have been used in studies and continuously developed; however, they are difficult to utilize daily life because of the inconvenience having attach multiple together difficulty long-term use due battery consumption required for high data sampling rates. overcome these problems, this study propose a multi-joint...
A flexible and bioactive scaffold for adipose tissue engineering was fabricated evaluated by dual nozzle three-dimensional printing. highly elastic poly (L-lactide-co-ε-caprolactone) (PLCL) copolymer, which acted as the main scaffolding, human derived decellularized extracellular matrix (dECM) hydrogels were used printing inks to form scaffolds. To prepare (3D) scaffolds, PLCL co-polymer printed with a hot melting extruder system while retaining its physical character, similar tissue, is...
A retrospective analysis was performed based on the medical records and imaging studies of 16 wrists (14 patients) with isolated partial intercarpal ligament tears (scapholunate ligament: 6 wrists, lunotriquetral ligament, 10 wrists) treated arthroscopic debridement thermal shrinkage. Three had Geissler grade 1 13 2 tears. Mean follow-up 52.8 months. Overall pain visual analog scale scores improved significantly ( P <.05) at rest during activities daily living heavy manual work....
The goal of this study was to compare treatment outcomes screw proximal femoral nails and helical investigate the effectiveness for intertrochanteric fractures. Forty patients with fractures were treated at our institution between January 2005 2007, a minimum follow-up 1.5 years. Seventeen (mean patient age, 67 years; age range, 45–89 men:women ratio, 3:14), 23 74 64–91 6:17). We evaluated mean operation time, amount bleeding, time ambulation, average union period, changes in neck shaft...
Stroke is a leading cause of disability among elderly individuals, and gait impairment typical characteristic related to the stroke severity experienced by patients. The aim this study propose novel classification method using symmetric features with recursive feature elimination cross-validation (RFECV). An experiment was conducted on data acquired from thirteen chronic patients eighteen participants. They walked treadmill at four different speeds based their preferred speed. In study,...
Purpose: This study investigated the clinical and radiologic outcomes of partial trapeziectomy suspensionplasty with a suture button for thumb carpometacarpal (CMC) joint osteoarthritis over 2-year follow-up period.Methods: retrospective involved 17 patients CMC (Eaton Littler stage II or III) treated using button. Clinical were evaluated visual analog scale pain, Quick DASH score, pinch grip strength, range motion. The trapezial space ratio (TSR) was used as parameter to evaluate...
Abstract Peripheral nerve repair is considered the gold standard treatment for complete transection injuries, yet achieving satisfactory functional recovery remains challenging due to muscle atrophy during time required axonal regeneration. This study investigated beneficial effects of 4-aminopyridine (4-AP), a potassium channel blocker, on neural and muscular recovery. Following right sciatic nerve, 40 mice underwent end-to-end using microscopic epineural sutures were randomly assigned...
We reviewed the clinical results of reconstruction performed for extensive tibial bone and soft tissue defect with a free vascularized osteocutaneous fibular graft in 46 patients (43 male 3 female). The mean duration follow-up was 30 months (range 13-76 months). age at time 41 years 15-66 years). In consecutive procedures grafts, bony union achieved 43 grafted fibulae an average 3.75 after operation. There were two delayed unions one non-union. Forty-four cutaneous flaps survived, failed due...
Revision Bankart operations frequently show capsulolabral buttress loss and recurrent soft tissue lesion. Capsulolabral augmentation is designed to increase glenohumeral stability by 2 separate mechanisms: deepening the glenoid concavity reducing capsular laxity. This accomplished shifting capsule labrum.A retained may of height slope at a certain period after surgery, regardless stability. Thus, authors wanted confirm importance an intraoperative establishment in terms...
Endoprosthetic reconstruction is widely applied for pathological fractures of the proximal humerus; however, functional impairment usually unsatisfactory. The aims current study are to evaluate reliability interlocking intramedullary (IM) nailing with cement augmentation as a fixation method in humeral lesions and assess outcomes.We reviewed 32 patients humerus who underwent IM augmentation. Functional scores pain relief were assessed outcomes.The mean follow-up period was 14.2 months....
