Abstract PDF: PURPOSE
To evaluation of usefulness of low-intensity ultrasound for nonunion and delayed union.
MATERIALS AND METHODS
For 5 months, we treated 7 delayed union and 8 nonunion using low-intensity ultrasound. After 5 months, in checked X-ray AP and Lateral view, when cortical bridge formation was done, we through union.
RESULTS
In 7 delayed union, 5 cases-2 femur, tibia, humerus, radius were healed. In 8 nonunion, 3 femur nonunion were healed. Union rate was 71% in delayed union 37.5% in nonunion.
CONCLUSION
we thought that the low-intensity ultrasound has capacity of induction of union and was considered as the method of treatment for delayed union.

Causative Factor for Cubitus Varus Deformity in Severely Displaced Supracondylar Fractures of the Humerus in Children : s Rotational Deformity of Distal Fragment Needed to be Acurately Reduced?: Seung Woo Suh, Jeong Ho Park, Jong Gun Oh, Seung Ju Chun, Jeong Ro Yoon, Seok Hyun Lee; J Korean Soc Fract 1997;10(3):712-717.

Abstract PDF: We reviewed retrospectively 53 cases of supracondylar fracture of humerus in children which were severely displaced(Gartland type III). All patients were treated with closed reduction and percutaneous pinning. Purpose of this study is to evaluate the residual effect of incompletely reduced fragment, especially of rotation of distal fragment(represented by fish-tail sign) on clinical relults. The quality of reduction was determined by carrying angle, varus tilting, existence of fish-tail sign and medial displacement. Of the 53 elbows, fish tail signs only presented in twelve cases(50.0%), medial tilting combined with fish tail in five(20.8%) and medial displacements in seven cases(29.2%). Final results by Flynn et al. were as follows; Excellent was in 40 cases(15.9%), Good in 6(11.3%), Fair in 1(1.8%), poor in 6(11.3%). Six cases of poor outcomes resulted from cubitus varus deformed elbow, of which cubitus varus deformity developed in 5 cases of medial tilted distal fragment, one developed in medially displaced fragment, and cases presented with fish tail sign(rotation of distal fragment) had no contribution to cubitus varus deformity yielding acceptable clinical results. In conclusion, even though the quantification of fish tail sign is needed, fish tail sign only presenting on fluorscopy might be acceptable in operative room.
