    Analysis of lower extremity alignment in achondroplasia - Interobserver reliability and intraobserver reproducibility
    (Lippincott Williams & Wilkins, 2006) Inan, M; Jeong, C; Chan, G; Mackenzie, WG; Glutting, J
    This study was designed to evaluate the reliability and reproducibility of frontal plane malalignment measurements using the mechanical axis deviation method in achondroplasia and to determine whether the patient's age has any influence on these measurements. A total of 150 anteroposterior standing radiographs of the lower extremities were randomly selected for the study. Radiographs were divided into three groups according to age: group 1, younger than 6 years of age; group 2, 6 to 10 years of age; group 3, older than 10 years of age. Interobserver agreement for the medial proximal tibial angle and the lateral distal tibial angle measurements were poor (0.32 and 0.38, respectively) in group 1, but agreement increased between observers with increasing patient age. Good to excellent intraobserver reproducibility was found in all groups, except measurement of the medial proximal tibial angle in group 1, where the results were poor (0.36). Significant measurement errors in the proximal and distal tibial joint lines are possible in children less than 6 years of age with achondroplasia.

    Correction of rotational deformity of the tibia in cerebral palsy by percutaneous supramalleolar osteotomy
    (British Editorial Soc Bone Joint Surgery, 2005) Inan, M; Ferri-de Baros, F; Chan, G; Dabney, K; Miller, E
    A percutaneous supramalleolar osteotomy with multiple drill holes and closed osteoclasis was used to correct rotational deformities of the tibia in patients with cerebral palsy. The technique is described and the results in 247 limbs (160 patients) are reported. The mean age at the time of surgery was 10.7 years (4 to 20). The radiographs were analysed for time to union, loss of correction, and angulation at the site of the osteotomy. Bone healing was obtained in all patients except one in a mean period of seven weeks (5 to 12). Malunion after loss of reduction at the site of the osteotomy developed in one tibia. Percutaneous supramalleolar osteotomy of the tibia is a safe and simple surgical procedure.
