Introduction: Knee deformity associated with osteoarthritis (OA) is one of the most common complications seen in patients referred to orthopaedic surgeons. High tibial osteotomy (HTO) is an accepted method for treatment of medial knee osteoarthritis with varus deformity. The aim of this study was to compare results of osteotomy methods in patients with genu varum (GV) deformity. Methods: In this cohort study, the sample consisted of 32 patients with genu varum deformity (42 knees) who were divided into two groups and matched according to age and gender. The patients were treated with open or closed wedge osteotomy. After surgery, they were followed-up and compared for 6 months. Results: The sample consisted of 25 women (87.2%) and 7 men (21.8%). Ten patients (31.2%) presented with bilateral deformity. The incidence of complications was the same for both procedures (12.5%); this included one peroneal nerve injury following closed wedge surgery. Overall, patient satisfaction was 87.5% and 75% for the open and closed wedge methods respectively. Operative time, days to full weight bearing, and days to return to routine activities were significantly shorter for patients treated with the open wedge method (p<0.001). Conclusion: Open wedged HTO is associated with shorter operating time, shorter recovery time, higher patient satisfaction, and probable lower risk of neurological injury.

STUDY DESIGN: Descriptive, cases series study. PURPOSE: To evaluate clinical findings and results of treatment of patients with spinal osteoid osteoma who underwent surgery. OVERVIEW OF LITERATURE: Osteoid osteoma is a benign tumor with spinal involvement rate of about 10%. It is manifested during adolescence with symptoms such as painful scoliosis. To treat the problem, operation on the patients and excising the nidus are suggested. METHODS: This descriptive study was conducted on 11 patients with spinal osteoid osteoma at our orthopedic educational center. All patients were treated through open surgery and nidus curettage. All samples were pathologically confirmed. Imaging methods (spiral computed tomography-scan) was used in preoperative planning. Scoliosis and other clinical findings were studied. RESULTS: The study was conducted on 11 patients comprising 6 females (54.5%) and 5 males (45.5%) with the mean age of 14.6 years. Mean deviation of scoliosis resulting from spinal osteoid osteoma was 22.8 degrees. There was more scoliosis in the involvement of the lumbar vertebra. In comparison with adults, scoliosis was more severe in youths. There was one case of vertebra body involvement with manifestation of painful scoliosis. Due to lack of careful preoperative examination, the surgery was repeated for this case. No sign of recurrence was observed in patients who underwent open surgery and all scoliosis in the follow-up had improved. CONCLUSIONS: Based on our findings, surgical excision of spinal ostoeid osteoma was successful and complete recovery was achieved in spinal deformity in the course of follow-up. Scoliosis is often seen during adolescence and lumbar involvement is more severe.

STUDY DESIGN: This is descriptive analytical study. PURPOSE: The present study aims at comparing treatment results found between the two groups comprising of patients who underwent posterior spinal fusion using thoracic pedicle screws and the ones who underwent combined anterior-posterior method, respectively. OVERVIEW OF LITERATURE: There was controversy about surgical techniques including anterior, posterior, or a combined anterior-posterior approaches are applied to treat non-congenital scoliosis with surgical indications. METHODS: Medical records of 50 patients suffering from thoracic non-congenital scoliosis with curves exceeding 70degrees were reviewed. In this study, 25 patients who underwent posterior spinal fusion using thoracic pedicle screws were compared with 25 patients who underwent combined anterior-posterior method. RESULTS: Patients treated through posterior-only and combined approaches were respectively hospitalized for 11.84+/-5.18 and 26.5+/-5.2 days (p=0.001). There was a significant difference between these two groups considering intensive care unit admission duration (p=0.001), correction in sagittal view of X-ray (p=0.01), and number of days the patients underwent traction (0.001). Finally, coronal view was corrected without any significant difference (p=0.2). CONCLUSIONS: According to our findings, it is hypothesized that posterior-only method is associated with some significant advantages and is an advisable method in patients with severe scoliosis over than 70degrees.

PURPOSEThe aim of this present study is to investigate the prevalence of alcohol and substance abuse (ASA) and its relationship with other risky driving behaviors among motorcycle drivers.

METHODSThis is a cross sectional study which is performed at Shiraz city of Iran. Data from motorcycle drivers were collected using a standard questionnaire in eight major streets at different times of the day. The data includes consumption of alcohol and other substances two hours before driving and some of the risky behaviors during driving.

RESULTSA total of 414 drivers with a mean ± SD age of (27.0 ± 9.3) years participated in the study. Alcohol or substance consumptions two hours before driving was significantly associated with risky driving behaviors such as using mobile phone during driving, poor maneuvering, and driving over the speed limit (both p < 0.001). It was also associated with carelessness about safety such as driving with technical defects (p < 0.001) and not wearing a crash helmet (p=0.008).

CONCLUSIONScreening for alcohol and substance consumption among motorcycle drivers is an efficient way to identify drivers that are at a greater risk for road traffic accidents.
