RESUMEN
INTRODUCTION: Heel pain is one of the common reasons why patients consult orthopaedic surgeons in an outpatient setting. The dorsal heel pain is often caused by a Haglund's deformity which is an exostosis of the posterior superior calcaneus. It often leads to Haglund's syndrome with calcaneal bursitis and Achilles tendinosis. This study aims to investigate the roll of MRI in diagnosis of Haglund's syndrome and its influence on therapy. MATERIALS AND METHODS: We retrospectively analysed data of 45 patients which clinically and radiologically confirmed Haglund's deformity. Patients were divided into two groups that either did not receive MRI (MRI_0) or received MRI (MRI_1). To evaluate the significance, Fisher´s test was used. A statistical significance was assumed at p < 0.05. RESULTS: The average age was 57.0 years. There was no significant difference in therapy comparing the groups MRI_0 and MRI_1. Haglund's syndrome was detected in 86.7% of all patients with Haglund's deformity. CONCLUSION: MRI does not influence the therapy of patients with Haglund's deformity. Therefore, the resources of this cost-intensive and limited type of investigation should be used elsewhere. In cases of atypical heel pain, the MRI might be useful.

BACKGROUND: Conventional nails rely on interlocking screws for axial and rotational stability. Such screws have poor fixation in patients with poor bone quality (osteopenia). The Fixion nail does not depend on interlocking screws-axial and rotational stability is instead achieved by nail expansion. Therefore, this nail may be better suited for patients with poor bone quality who require humeral stabilization. METHODS: The system was used to manage 25 unstable humerus shaft fractures in osteoporotic bone. An antegrade approach was used in 18 patients and a retrograde approach was used in 7 patients. RESULTS: There were no intra- or postoperative complications. Postoperatively, all fractures were stable and had healed by week 16. The mean operative time was 35 +/- 10 minutes (+/- SD) including 1.5 +/- 0.5 minutes of fluoroscopy time. CONCLUSION: The results of this study show that use of this nailing system is associated with minimal complications, predictable fracture healing, and excellent functional outcomes in a cohort of elderly patients with poor bone quality and humeral shaft fractures requiring stabilization. Further confirmation by larger prospective trials is necessary.
