Turkey still lacks a comprehensive series indicating the incidence and diagnostic distribution of bone and soft tissue tumors. The presented data would add to our knowledge on the specific rates of the bone and soft tissue tumors in Aegean region.

We report a prospective series of 33 unicompartmental knee arthroplasties (UKAs) operated for a spontaneous osteonecrosis of the knee (SPONK) compared with 35 UKAs operated for osteoarthritis (OA). The mean follow-up was 5 years. Preoperative functional score in the SPONK group was significantly lower than that in the OA group. The results were comparable in terms of pain, knee score and function. At the last follow-up, the survival rate was 92.8% for the SPONK group and 95.4% for the OA group. We found a higher rate of radiolucencies in the SPONK group, however, without any clinical symptoms. The UKA is a good option in the treatment of SPONK.

Osteoarthritis is a chronic disorder characterized by joint cartilage degeneration with concomitant changes in the synovium and subchondral bone metabolism. Many conservative treatment modalities, one of which is intra-articular injections, have been described for the treatment of this disorder. Traditionally, hyaluranic acid and corticosteroids are the agents that have been used for this purpose. Recently, polyacrylamide hydrogels are being used widely. Biocompatibility, nonbioabsorbability, and anti-infectious effect obtained by silver addition made polyacrylamide hydrogels more popular. In this paper, we present a case and the method of our management, in whom host tissue reaction (foreign body granuloma, edema, inflammation, and redness induration) has been observed, as the first and unique adverse effect reported in the literature.

Objectives: This study aims to describe our surgery technique and discuss patients treated through the dorsoulnar artery (DUA)-based technique of osseous and osteo-fascio-cutaneous vascularized ulnar bone grafting. Patients and methods: Between January 2011 and January 2015, six male patients (median age: 22.5 years; range, 20 to 24 years) who underwent surgery during which the technique of DUA ulnar bone graft was utilized. One patient with scaphoid nonunion, three patients with Kienböck’s disease, and two patients with a traumatic metacarpal defect were retrospectively evaluated. The joint range of motion (ROM), grip strength, Disabilities of the arm, shoulder and Hand (DASH) questionnaire score and Visual Analog Scale (VAS) score, and radiographies before and after surgery were examined. Scintigraphy was performed at 12 weeks postoperatively to monitor the viability of the bone graft. Results: All patients showed improvements in the ROM, grip strength, VAS, and DASH scores. According to the radiographic examination, bone union was achieved in all patients and the scintigraphy revealed that vascularization was detected in the bone tissue. Conclusion: The advantages of DUA-based vascularized bone graft are good bone quality and quantity and versatility due to its long pedicle. The osteo-fasio-cutaneous DUA flap seems to be effective in the treatment of traumatic metacarpal bone defects accompanied by skin loss. The DUA-based vascularized ulnar bone may be a source for scaphoid and lunate biological bone reconstruction.

Objective: In this study, we aimed to evaluate clinical presentations, histopathological diagnosis, surgical treatment modalities and complications of patients operated for a parotid gland mass. Methods:Medical records of 100 patients who were operated for a parotid gland mass between 2010 and 2016 years evaluated retrospectively.Results and discussion: 49 (49%) of these patients were female and 51 (51%) were male. The mean age of the patients was 47.9. Post-operative histopathologic assessement, 89 of the cases were found to be primary benign, 7 of the cases primary malignant and 4 of the cases secondary malignant. For benign tumors the most common histopathology was pleomorphic adenoma in 45 (45%) patients, and the second was whartin tumor in 32 (32%) patients. Mucoepidermoid carsinoma was seen as the most common primary malign tumor (3 patients). All cases with primary malignancy continue to follow-up visits and the average follow-up period is 37 months. However, all of the cases with secondary malignant parotid tumors were died due to malignancy. Complication ratio was 12% and facial paresis was the most common complication. Conclusion:Subtotal parotidectomy is an adequate and efficient surgical procedure for the benign parotid tumors and complication risk is considerably low when applied carefully. However it may be required complementary total parotidectomy for malignant tumors. The prognosis is very good especially for the primary malign parotid tumors. However, it is not satisfactory for the secondary malign tumors.
