This study aims to compare clinical and radiological follow-up results of a rectangular (SL-Plus®) or a round (Synergy®) femoral component in patients with Crowe type 2 or 3 hip dysplasia operated with total hip arthroplasty (THA) without a shortening osteotomy.Between January 2012 and December 2017, a total of 34 hips of 30 female patients (mean age: 42.9±11.6 years; range, 24 to 66 years) were retrospectively analyzed. All patients were evaluated using the Harris Hip Score (HHS) and Visual Analog Scale (VAS) for pain pre- and postoperatively. Intra- and postoperative complications were noted. Evaluation criteria included leg length discrepancy, stem subsidence, bone atrophy or hypertrophy around the stem according to Gruen zones, operative time, and intraoperative blood loss. Correlation analysis of radiological, clinical findings, and stem size was performed.The mean follow-up was 61.3±27.2 months. The mean postoperative HHS was 89.3±6.2 vs. 93.1±9.1, and the mean VAS score 1±0.6 vs. 1±0.8 in round and rectangular stem groups at the final follow-up. No significant differences were detected between the groups in any of the evaluated parameters, except for a more severe degree of stress shielding observed in the round stem group. Round stem size was positively correlated with a more severe stress shielding (r=0.55, p=0.020). No patient had to be revised during the follow-up period. The overall complication rate was 9%.Successful and comparable results can be obtained with cementless THA in patients with high riding dysplastic hips implanting either of the femoral components, a rectangular or a round stem. Although the round stem was associated with more common proximal stress shielding, this was not associated with worse clinical outcomes.

This study focused on the anatomical characteristics and variations of intercostobrachial (ICBN) nerve and median nerve to investigate the possible use of ICBN in restoration of sensory damage of hand after traumatic median nerve injury and to evaluate the feasibility of ICBN neurotization to median nerve.Variations of ICBN were noted in 16 axillary region dissections of eight cadavers. Measurements for ICBN's suitability in terms of neurotization to brachial plexus were done with millimetric devices. The distance of ICBN to the distal end of the lateral (LCMN) and medial (MCMN) contributions of the median nerve and the diameters of ICBN, LCMN, and MCMN were measured.Fifteen axillary dissections exhibited ICBN, whereas it was absent on the left side of one of the cadavers. The mean diameter of ICBN at its origin was 2.0±0.7 mm and the mean diameter of ICBN at its coaptation point was 3.1±0.9 mm. The mean diameter of the LCMN was 3.9±2.0 mm, the mean diameter of MCMN was 3.5±0.9 mm. The length of ICBN was found to be adequate at both 45 and 90° of shoulder abduction to be extended to both LCMN and MCMN. The diameters of LCMN and MCMN were not significantly correlated with the diameter of ICBN both at origin and at coaptation point (LCMN: p=0.55-0.63 and MCMN: p=0.89-0.85). There is no significant difference between the diameter of LCMN and the diameter of ICBN at its coaptation point (p=0.168) and also between the diameter of MCMN and the diameter of ICBN at its coaptation point (p=0.232).All ICBNs dissected showed adequate length to reach the lateral and medial contribution of the median nerve directly. The ICBN could be a feasible candidate since its diameter was close to LCMN and MCMN according to the descriptive and inferential statistics.

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.
