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.

Remodelling of Angular DeforMity after Femoral Shaft Fractures in Children: Young Bae Pyo, Sang Ho Ha, Hong Moon Sohn; J Korean Soc Fract 1998;11(1):116-122. Published online January 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.1.116

Abstract PDF: The common sequelae after femoral shaft fractures in children are leg-length discrepancy, angular deformity and rotational deformity. Overgrowth after the conservative management of fractures has been clearly defined, and it has been reported that rotational deformities can remodel. The importance of angular deformity after fracture is less clear although it has been reported as many as 40% of cases. So, authors reviewed 15 children (16 cases) with unilaterral femoral shaft fractures who had more than 10 degrees angular deformity after conservative treatment and observed the remodelling of deformity both at the fracture site and the physes. after average follow up of 34 months, the results were as follows 1. The average correction was 84% of the initial angular deformity; the physes contributed more than the fracture site. 2. The anterior angulation remodelled better than the varus angulation. 3. Younger children remodelled better and the magnitude of the angulation influenced the degree of remodelling.

Remodelling and Reangulation following the Fracture of Both Bones of the Forearm in Children: Sung Tae Lee, Jeong Hwan Oh, Eui Hwan Ahn, Hyuck Jun Lee; J Korean Soc Fract 1997;10(4):972-978. Published online October 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.4.972

Abstract PDF: One-hundred fifty children underwent closed reduction for the fracture of both bones of the forearm were retrospectively reexamed with an average follow-up time of 28.7 months(range, 13-60 months). Patients were divided into three groups of 50-complete fractures, 50-green-stick fractures broken intact cortex and 50-green-stick fractures preserved intact cortex. The rate of the reangulation after closed reduction was lowest on the green-stick fractures preserved intact cortex. Forty-seven patients with residual angulation after healing were divided into two age groups of 4-10 years and 10- 15 years at the time of fracture. In children younger than 10 years of age with residual angulation after distal fractures of both bones of the forearm, the change of orientation of the epiphyseal plate toward the normal seemed to account for nearly all the actual correction at the site of fracture. The hinge should be used to aid in an accurate and stable reduction. The importance of the orientation of the epiphyseal plate is related to the distance between the fracture site and the epiphyseal plate according to the age of the patient.

Overgrowth and Remodelling after Femoral Shaft Fractures in Children: Seung Rim Park, Hyoung Soo Kim, Joon Soon Kang, Woo Hyeong Lee, Hyun Yang Chun; J Korean Soc Fract 1997;10(1):226-232. Published online January 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.1.226

Abstract PDF: Fifty-two femoral shaft fractures in children, treated conservatively, were studied clinically and radiographically to access the overgrowth and it is related factors. Among them, we reviewed fourteen children(16 cases), who had angular deformities over 10 after union for the spontaneous correction of the angular deformity. They had an average follow-up of 40.5 months and 32.4 months. The results were as follows : 1. The average of the overgrowth was 9.9mm. 2. The overgrowth was influenced by the age, but was not promoted by other factors. 3. The average overgrowth of the age group between 4 and 9 was 10.8 +/- 2.7mm. 4. The average correction was 78% of the initial angular deformity, 77% had occurred at the physes and 23% at the fracture site. 5. There was no close relation between the remodelling rate and degrees of initial deformity.
