Remodelling of Angular Deformity in Birth-Associated Femoral Shaft Fracture: Soon Hyuck Lee, Sung Tae Lee, In Rok Yoo, Seoung Joon Lee; J Korean Fract Soc 2005;18(3):330-334. Published online July 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.3.330

Abstract PDF: PURPOSE
To find out the process of bone remodelling and risk factors in birth-associated femoral fracture.
MATERIALS AND METHOD
We evaluated the four femoral fractures in three neonates about the obstetric and family history, and measured the angulation at the fracture site and the angle between the proximal and distal epiphysis of the femur on the radiographies taken at regular intervals.
RESULTS
The incidence of birth-associated femoral fracture was 0.06%. In two cases, fracture angulation and interepiphyseal angle had been decreased. However the angular deformity was worsened in two cases, but the interepiphyseal angle had been decreased regardless to the change of fracture angulation. So the alignment of epiphyseal plate came to normal alignment of joint surface.
CONCLUSION
The underlying disorder should be searched, because of its rarity. The physeal reorientation that makes joint alignment near normal irrespective of amount of angular deformity is assumed as the predominant mechanism in remodelling process of the angular deformity.

Radiologic Result of Treatment of Intertrochanteric Fracture Using Compression Hip Screw: Involvement of Lateral Cortex: Suk Ha Lee, Sung Tae Lee, Kwang Jun Oh, Yong Bae Kim, Woo Seung Lee, Ji Sung Jun, In Rok Yoo, Jung Sup Keum; J Korean Fract Soc 2005;18(2):115-119. Published online April 30, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.2.115

PURPOSE
To assess the meaning of the unstable intertrochanteric fracture of femur with involvement of lateral cortex by analysing the radiologic result of the surgical treatment using a compression hip screw.
MATERIALS AND METHODS
Classifing patients (who has taken the surgical treatment for intertrochanteric fracture of femur using compression hip screw from January 1999 to June 2002) in our hospital with 24 patients who had not much difference statistically in the compression screw located within the femur, Tip-Apex distance (TAD) the Singh Numerical Value of osteoporosis. The results were divided into two groups, group A (without fracture extends through lateral cortex of femur: 16 cases) and B (fracture extends through lateral cortex of femur: 8 cases), when analyzing it. And then analyzed the final examination in the evaluation of electrical potential level by radiology, change of the inside and outside of neck-shaft angle, descent level of the screw and the change of the neck-shaft angle.
RESULTS
In the latest follow up, the sliding amount of the screw in group B, the average was 14.9+/-9.3 mm, and 6.7+/-3.6 mm in group A. There was no difference statistically (p value>0.05). In the varus change in group B, the average was 8.00+/-8.12degrees and in group A it ws 2.75+/-2.63degrees There was statistical difference(p value<0.05). In displacement after operation, it was 7.60+/-2.61 mm in group B and 0.5+/-1.80 mm in group A. There was statistical difference (p value<0.05).
CONCLUSION
The intertrochanteric fracture with involvement of lateral cortex of femur have to be considered as unstable fracture having tendency of displacement.
