ABSTRACT
In clinical practice, recurrent Achilles ruptures have been noted to occurr at the original ruptured site. However, reports of new developed fresh rupture of the Achilles tendon in other sites are is extremely rare. Our report is about one uncommon case of a traumatic calcaneal tuberosity avulsion fracture following augmented repair, which was performed using the Krackow locking loop technique. We performed open reduction and intra-osseous fixation using a suture anchor. This procedure was done through the primary longitudinal incision for the calcaneal avulsion fracture fragment. After 6 months of follow-up, our patient has achieved a complete functional recovery and he can normally perform daily and work-related tasks without pain.
ABSTRACT
PURPOSE: A conventional magnetic resonance imaging (MRI) was conducted in supine position, showing a slight different from that conducted in upright position. Therefore, we simulated the upright position by applying the axial load on a lumbar spinal stenosis patient and measured the change of neural tube size in axial load and standardized the data. MATERIALS AND METHODS: We compared the axial loading MRI obtained from spinal stenosis patients who visited Wonkwang University Hospital outpatient clinic between October 2010 and May 2011 showing radiologic and physical symptoms. RESULTS: Neural tube sizes by conventional MRI were as follows: 195.57 mm² and 203.20 mm² on average between the left and right sides in L3/4; 194.64 mm² and 211.43 mm² on average in L4/5; and 199.38 mm² and 203.04 mm² on average in L5/S1. Neural tube sizes by axial loading MRI were as follows: 166.43 mm² and 174.27 mm² on average between the left and right sides in L3/4; 154.81 mm² and 158.67 mm² on average in L4/5; and 148.48 mm² and 157.19 mm² on average in L5/S1. Changes of neural tube sizes in L3/4, L4/5, and L5/S1 had a significant correlation (p<0.05). CONCLUSION: The axial loading device was an excellent tool in simulating the upright position for spinal stenosis patients, and the change of neural tube sizes reproduced for the upright position was statistically significant. This is thought to be meaningful for clinical applicability.
