The aim of the study was to investigate the relationship between the interpedicular distance increase ratio and the ratio of canal compromise in thoracolumbar burst fractures.Thirty-one patients (18 male and 13 female) with an average age of 30.8 (14-57) who had been treated for thoraco-lumbar burst fractures in the Department of Orthopaedics and Traumatology were included in the study. The initial anteroposterior radiographs of the patients were used to calculate the increase ratio of interpedicular distance (both from medial-to-medial and from center-to-center). The area measurements from the computerized tomography or magnetic resonans images were used to calculate the canal compromise. The relationship between the increase ratio of interpedicular distance and the ratio of canal compromise was investigated by correlation and linear regression analysis.There was a 'very good' correlation between the from medial-to-medial and from center-to-center measurements of interpedicular distance (Pearson correlation coefficient: 0.89, p0.001). The correlation between the ratio of canal compromise and from medial-to-medial and from center-to-center measurements of interpedicular distance was 'good' with Pearson correlation coef-ficients of 0.60 and 0.63, respectively (p0.001). No statistically significant relationships were found between the fracture levels, types, neurologic status of the patients, and the increase ratio of interpedicular distance or the ratio of canal compromise.Depending on the correlation coefficients which were obtained in this study: To predict the canal compromise from the ratio of interpedicular distance increase is not a reliable method for all of the patients.

Stable fracture fixation is important in the treatment of intertrochanteric femur (ITF) fractures in the elderly population to prevent the loss of reduction, achieve early mobility, and restore independence. The aim of this study was to present the results of surgical treatment of stable and unstable ITF fractures using a trochanteric antegrade intramedullary nail with two cephalocervical screws in an integrated mechanism (Intertan®; SmithNephew, Memphis, TN) and evaluate the relationship between the loss of reduction and screw position in the femoral neck in two planes.The authors investigated all varus misalignments and losses of reduction in 57 patients (22 males, 35 females) treated for ITF fractures with the Intertan® between 2010 and 2011. Two indices (screw alignment index in the frontal projection [SAIcoronal] and screw alignment index in the lateral projection [SAIsagittal]) were defined to evaluate the loss of reduction. Patients were also evaluated according to the Harris hip score and Barthel independence index.The mean patient age was 77.1 years. The mean follow-up period was 21.7 months. All patients achieved complete union. We did not detect any varus collapse or loss of reduction. At the end of the follow-up period, the mean Barthel independence index was 90.7, and the mean Harris hip score was 83.7.The use of a trochanteric antegrade intramedullary nail with two cephalocervical screws allows for linear intraoperative compression and rotational stability of the head/neck fragment, prevents reduction loss, and has a wide application area in the femoral head. Its inherent continuous stability permits early weight-bearing and mobilization. It is a safe and an efficient option for the treatment of ITF fractures.

The aim of this study was to evaluate the results of the endoscopic calcaneoplasty technique for the treatment of retrocalcaneal bursitis and Haglund's disease.This study included 30 feet of 28 patients who underwent endoscopic surgery for Haglund's disease between 2003 and 2011. The inflamed bursa and posterosuperior surface of the calcaneus were removed with a shaver and bone resection performed until there was no friction on the Achilles tendon with the ankle in dorsiflexion. All patients were discharged on the same day and allowed full weight-bearing at the second postoperative week. American Orthopedic Foot and Ankle Society (AOFAS) scores and patient satisfaction were recorded.Average follow-up was 58.4 months. AOFAS scores significantly improved from a postoperative average of 52.6 points to 98.6 points at the final evaluation (p0.005). All patients were satisfied with the result of the operation.Endoscopic calcaneoplasty with the patient in the prone or supine position appears to be a safe and effective surgical procedure for the treatment of retrocalcaneal bursitis and Haglund's disease.
