Category: Trauma Introduction/Purpose: The aim of this study was to evaluate and compare the clinical and radiological results of internal fixation with headless cannulated screw and locking compression distal ulna hook plate for the fracture at the base of fifth metatarsal bone, Zone 1. Methods: From April 2012 to April 2015, thirty cases (29 patients) were evaluated retrospectively. The mean follow up periods was 13 months. There were divided two groups based on use of the screw (group A, n=15) or the plate (group B, n=15).We measured the displacement to diastasis of the fracture on the foot oblique radiographs taken pre- and post-operatively in each group, checked the time to bone union and the difference of the reduction distance in each group. Clinical results were evaluated using American Orthopedic Foot and Ankle Society (AOFAS) midfoot score at 12 months postoperative. Results: In group A, the mean time to union was 54.2±9.3 days, the mean displacement to diastasis improved to 0.3±0.4 mm postoperatively (p<0.001), and the mean reduction distance was 2.9±1.0 mm. In group B, the mean time to union was 41.5±7.0 days, the mean displacement to diastasis improved to 0.06±0.2 mm postoperatively (p<0.001), and the mean reduction distance was 4.1±1.6 mm. AOFAS score was verified 97.7±3.4 in group A and 98.2±3.2 in group B. The time to union was significantly different between groups A and B (p=0.01).There were no complications. Conclusion: We suggest that the plate is more effective method for the shorter union time in surgical treatment of fifth metatarsal base fractures.

Category: Ankle, Trauma Introduction/Purpose: Osteoporotic fractures in ankle have often included small bone fragments and were very unstable. There had been tried to fix them for anatomical reduction, using variable methods. However, it was not easy to keep the reduction, especially in elderly. The purpose of this study was to evaluate the results of the treatment in ankle fractures with small fragment using claw plate in elderly. Methods: The nineteen patients with ankle fractures, which included the small fragments, from january 2012 to july, 2014 were evaluated retrospectively. All patients were more than 65 years and had osteoporosis. The authors have been tried to fix it using claw plate in all cases. The mean follow up period was 15 months(range, 12month to 18month). The claw plate was designed to catch the small fragment and made of tubular plate or locking tubular plate with bending it after cutting the distal end of them. It had two different hooks to keep the reduction and the fragment. Functional outcome scores were obtained using Olerud Molander Ankle score(OMA), VAS, and American Orthopedic Foot and Ankle Society (AOFAS) score at 2, 3, 6, 9, 12 month after the operation, when each patient underwent a physical examination and radiography. There was evaluated statistically by SPSS 19.0 Results: There were no complication, such as metal failure and loss of reduction. AOFAS score improved from 56.4±3.1 at 2 month to 93±1.5 at 12 month(p=0.01). The VAS improved from 6.2±0.9 at 2 month to 1.2±0.8 at 12 month(p=0.001). OMA score improved from 15.5±0.2 at 2 month to 75±2.5 at 12 month (p=0.001). There was significant difference, statistically. There was obstained the bony union in 3 months after the operation in all cases Conclusion: We suggested that the claw plate is the alternative method to fix the osteoporotic ankle fracture with small fragments in elderly, without complications
