Objective The aim of this study was to evaluate the clinical features and functional results of patients with parosteal lipomas. Methods A total of 12 patients (8 females and 4 males; mean age: 45 (10–62) years) with parosteal lipomas who were treated between April 1986 and April 2014, were included into the study. The medical records of the patients were reviewed to analyze the clinical features and functional results of the patients. Results Of the 12 lipomas, 5 were localized in the proximal arm, 4 in the forearm, 1 in the distal arm, 1 in the distal thigh and 1 in the distal tibia. All patients presented with a progressive, slow . . .-growing mass that was associated with thumb extension weakness in 1 case, and brachialgia-like symptoms in 1 case. Plain radiographs showed a juxtacortical mass in all cases and irregular ossification in 3 cases. In all cases, marginal excision was performed and no clinical recurrence was observed after a mean follow-up of 16 months. Conclusion Parosteal lipomas are uncommon tumors that can be diagnosed with their characteristic radiological features. Parosteal lipomas occurring in the proximal radius may easily cause paralysis of the posterior interosseous nerve or muscle weakness.

Objective: Rotator cuff repair is associated with multiple complications, significant morbidity, and reintervention, which could be mitigated by postoperative chemodeneveration with botulinum toxin-A (BTX-A). This study evaluated the antinociceptive and paralytic effects of BTX-A on an experimental supraspinatus repair rat model and its effect on functional outcomes (running performance). Methods: Thirty rats were grouped into the surgical repair group (group A), repair + intramuscular BTX-A group (group B), or control group (group C). At the end of the 3-month follow-up, running performance of the rats on a motorized treadmill was . . .evaluated in four time periods (0-30 min, 30-60 min, 60-90 min, and 90-110 min), and penalty points (i.e., number of shock stimuli per lane) were recorded. Afterwards, the supraspinatus muscles were removed and evaluated histologically. Results: Regarding running performance, group B received significantly fewer penalty points than did group A ( Daha fazlası Daha az

Objective: Delaying the treatment of bone and tendon injuries may cause unmanageable complications. Bonesetters continue to cause delays in treatment. The purpose of this study was to analyze the medical outcomes of delay due to bonesetter intervention and factors affecting patient treatment preference. Methods: Among outpatients treated at our clinic between January 2010-December 2012, bonesetter- intervened patients were included, and patient demographics, clinical outcomes, and possible social factors were retrospectively analyzed. Clinical examinations and radiological screening measurements were used to evaluate outcomes. Resul . . .ts: Of the 162 patients, 97 (59.8%) were male, and mean age was 27.5±9.4 years. Eighty-nine (54.9%) of the patients lived in a rural area, and 108 (66.7%) underwent surgery. Bonesetter preference was dictated primarily by elderly relatives (47.6%) or neighbors (33.3%). Patients with a primary school education and unemployed patients mostly preferred bonesetters (p=0.03 and Daha fazlası Daha az

Objective: Bone protein extract (BPE) usually requires a carrier or a scaffold for implantation. We aimed to compare the effect of equine-derived BPE, an osteoinductive agent composed of a high amount of type-I collagen and other bone proteins (Colloss-E), with that of human demineralized bone matrix (DBM) for treating cavitary bone defects not requiring scaffold use. Methods: Rabbit distal femoral condyle was used as a stable cavitary bone defect model. Bone defects of 6-mm diameter and 10-12-mm depth were created in the femoral condyles. Rabbits were assigned into the equine-derived BPE (BPE) , human-derived DBM (DBM), and control . . . (C) groups. Approximately 20 mg of BPE was implanted into the defect in the equine-derived BPE group (n=6), whereas 0.3 cc of DBM was implanted in the DBM group (n=6). Defects were left empty in the C group (n=6). The defect area was histologically examined after 6 weeks. Results: There were no instances of macroscopic defect collapse or failure. Histopathological examination revealed that the BPE group had better scores (statistically significant) than both the other groups in terms of quality of union. The BPE group also had higher scores than the DBM group in terms of graft incorporation and new-bone formation. Conclusion: The current study revealed results consistent with those of the previous studies concerning BPEs. Equine-derived BPE was found to be successful for treating cavitary bone defects not requiring scaffold use. © 2015 Turkish Association of Orthopaedics and Traumatology Daha fazlası Daha az

Objective: The aim of this study was to investigate the effect of electromagnetic fields (EMFs) at 900 MHz frequencies on bone fracture healing. Methods: The study included 30 adult male Wistar albino rats (average weight: 256 g) divided into two equal groups. Transverse fracture was created manually by pressing a finger on the right tibias of all rats and fractures were fixed intramedullary using a K-wire. Rats in Group 1 were exposed to EMF at 900 MHz frequency 30 minutes a day, 5 days a week for 8 weeks. Group 2, the control group, was kept under the same experimental conditions without EMF exposure. Radiological, mechanical and . . .histological examination of tibial fracture healing was performed. Results: There was a significant difference between radiological, histological and manual biomechanical scores of the study and control groups (p=0.020, p=0.006 and p=0.032, respectively). All scores were lower in the study group than the control group. Conclusion: Results of this study demonstrate that EMF at 900 MHz of frequency emitted from cellular phones has a significantly negative effect on bone fracture healing in a rat tibia model.©2013 Turkish Association of Orthopaedics and Traumatology Daha fazlası Daha az

Objective: This experimental study investigates the effectiveness of expanded polytetrafluoroethylene (Dualmesh®, Gore Medical, Flagstaff, AZ, USA), sodium hyaluronate-carboxymethyl cellulose (Seprafilm ®, Genzyme, Cambridge, MA, USA), and polysiloxane (silicone) as anti-adhesive barriers for inhibition of fibrosis in the subacromial area following rotator cuff repair. Methods: Rabbit rotator cuff tenotomy and repair was conducted on 24 rabbits in 4 groups: control (Group A), Dualmesh® (Group B), Seprafilm® (Group C), and silicone (Group D). Anti-adhesive barrier materials were sutured over the repaired rotator cuff. Macroscopic and . . . histological evaluations were made at the end of the sixth postoperative week. Results: Macroscopic evaluation revealed that minimal adhesion occurred in the control and silicone groups, while the Seprafilm® and Dualmesh® groups showed evidence of fibrosis. Microscopic evaluation revealed diffuse fibrosis and collagen accumulation in the Dualmesh® and Seprafilm® groups, whereas minimal collagen deposition and inflammatory cell reaction was found among the silicone and control groups. Significant differences were found between the silicone and Dualmesh® (p=0.001) and silicone and Seprafilm® groups (p=0.002), as well as between the control and Dualmesh® (p=0.002) and control and Seprafilm® groups (p=0.002). Conclusion: Expanded polytetrafluoroethylene (ePTFE/Dualmesh®) and sodium hyaluronate carboxymethyl cellulose (SH-CMC/Seprafilm®) did not prevent or attenuate postoperative subacromial fibrosis following cuff tear repair. Nor did silicone prevent or attenuate fibrosis. More detailed research is needed for development of an effective anti-adhesive barrier for use after rotator cuff tear surgery. © 2016 Turkish Association of Orthopaedics and Traumatology Daha fazlası Daha az
