Hemiarthoplasty with Bone Block Graft and Low Profile Prosthesis for the Comminuted Proximal Humerus Fractures: Chung Hee Oh, Joo Han Oh, Sae Hoon Kim, Ki Hyun Jo, Sung Woo Bin, Hyun Sik Gong; J Korean Fract Soc 2008;21(3):213-219. Published online July 31, 2008; DOI: https://doi.org/10.12671/jkfs.2008.21.3.213

PURPOSE
To evaluate the outcome of hemiarthroplasty with bone block graft and low profile prosthesis (Aequalis(R) fracture prosthesis) for the comminuted proximal humerus fractures.
MATERIALS AND METHODS
Sixteen low profile prostheses were used since July 2004, and 11 patients were followed-up for average 19.9 (12~30) months. Their mean age was 67.3 (52~78) years. Pain and satisfaction visual analog scale (VAS), range of motion, and modified UCLA score for hemiarthroplasty were evaluated at every visit. Radiography was also checked for stem position, loosening, and tuberosity union.
RESULTS
Mean pain VAS was 2.7 (0~5), and mean satisfaction VAS was 8.4 (5~10). Mean active forward flexion was 137 degrees (90~170), external rotation at side was 45.5 degrees (25~70), and internal rotation at back was T10 (T7~L1). Modified UCLA score was 19 (12~30) at final visit. All stems were stable, and there were no loosening at the final follow-up. All tuberosities were united except two tuberosity absorptions.
CONCLUSION
The outcome of hemiarthroplasty with bone block graft and low profile prosthesis was comparable to other implants for comminuted proximal humerus fractures. This system had unique advantages for tuberosity union. Further study with more patients and longer follow-up are necessary to clarify the effectiveness of this prosthesis.

Subtalar Distraction Arthrodesis for Calcaneal Malunion: Hyung Jin Chung, Jae Kwang Yum, Kook Jin Chung, Jae Min Jeon; J Korean Fract Soc 2006;19(1):34-40. Published online January 31, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.1.34

Abstract

PURPOSE
To evaluate the results and efficacy of the subtalar distraction arthrodesis on patients with complications due to malunion after intra-articular calcaneal fracture.
MATERIALS AND METHODS
From October 2001 to September 2004, we operated on 10 patients (14 cases). There were 9 male patients and one female; their mean age was 41 years old. Ten cases among them were operated initially. The mean period between initial injury and arthrodesis was 18 months. The mean follow up period was 16 months. During the operation, we used extensile lateral approach and arthrodesis was performed using tricortical bone block and cannulated screws. The ankle-hindfoot scale was used for clinical evaluation. In radiologic analysis, plain X-ray and CT of the both feet were examined for union and various parameters.
RESULTS
Thriteen cases achieved radiologic bone union. The mean ankle-hindfoot scale (maximum: 94 points) increased from 52.4 points preoperatively to points 77.2 at the final follow-up. The radiologic analysis of the pre and postoperative standing lateral radiograph showed mean increase of 6.9 mm in talo-calcaneal height, 5.2 degrees in talocalcaneal angle, 4.3 degrees in talar declination angle and average decrease of 4.5 degrees in talo-first metatarsal angle.
CONCLUSION
The short term result of the subtalar distraction arthrodesis using tricortical bone block was promising, but longer follow-up will be needed.
