    (Springer-Verlag France, 2015) Altan, Egemen; Özbaydar, Mehmet Uğur; Tonbul, Murat; Şenaran, Hakan; Temelli, Yener; Akalan, Ekin
    Background Natural consequence of repetitive ankle sprains is the chronic ankle instability. Objective of this study was to clarify the gait patterns of functional ankle instability (FAI) patients after arthroscopic synovectomy, but also assessment of postoperative recovery. Patients and methods Arthroscopic synovectomy was performed to 14 FAI patients with history of unilateral repetitive ankle sprains, pain, and subjective sensation of instability. At a mean 54 months of follow-up (27-84), clinical assessment was conducted with respect to pain, number of ankle sprains, and American Orthopaedics Foot and Ankle Society (AOFAS) scores. Gait analysis was conducted to determine the temporospatial, kinetic and kinematic parameters at the last follow-up. Results Mean AOFAS scores increased from 68 (range 55-75) to 89 (range 77-100) points (P<0.01). Mean ankle sprains was 13 in a period of 23 (range 14-48) months (0.58 per month) and decreased to three sprains in a mean time period of 54 months (0.053 per month) (P<0.01). Mean preoperative and postoperative VAS scores were 8.0 and 2.9, respectively (P<0.01). During gait analysis, no significant differences were found in ankle joint, including foot progression angles, ankle dorsi-plantar flexion degrees and ground reaction forces (P>0.01). Among temporospatial parameters, only double support time showed a significant difference (P<0.01). All patients were satisfied from the procedure and returned to their previous activity level. Conclusion Improved long-term clinical results and scores were obtained in our patient group when compared with the preoperative scores. Also, three-dimensional gait analysis showed that the involved ankles demonstrate similar gait patterns to the uninvolved ankles in patients with FAI. © Springer-Verlag France 2014.

    Comparison of two different measurement methods to determine glenoid bone defects: area or width?
    (MOSBY-ELSEVIER, 2014) Altan, Egemen; Ozbaydar, Mehmet Ugur; Tonbul, Murat; Yalcin, Levent
    Background: This study compared two different techniques that have been used to measure the glenoids of patients with recurrent anterior shoulder dislocation. Methods: We analyzed 36 patients who had received arthroscopic Bankart repair for anterior shoulder instability. Retrospectively, 3-dimensional computed tomography images of both shoulders were available for these patients. Two measurement methods were compared to determine the glenoid defects. One of these techniques is based on linear measurement, previously defined as the glenoid index. The other method is based on surface area measurement. Subsequently, 3 more diameters and the average values obtained from these diameters were compared with the surface measurement method. Pearson correlation coefficient (r) was assessed to determine the relationship. Results: There was an almost perfect relationship between measurement methods when the defect area was less than 6% of the inferior glenoid circle (r, 0.915; P < .001). This relation decreased and the difference became more pronounced (r, 0.343; P=.657) when the bone loss exceeded 14% of the inferior glenoid circle. The highest correlations with the actual defects were the average values obtained from 4 different diameters (r, 0.964; P < .001) and the 4-o'clock position of the single diameter measurements (r, 0.860; P=.001). In addition, 11 patients had crescent-like defects, demonstrating a relatively low correlation between the measurement methods (r, 0.679; P=.021). Conclusion: Although the best correlation was achieved from average values obtained from different diameter positions, in practical use, we advise a linear measurement to estimate the glenoid bone loss at the 4-o'clock position to achieve a high correlation between the measurement techniques.
