The effects of maximal radial bowing on forearm rotation in pediatric diaphyseal forearm fractures.

PURPOSE: To evaluate the effects of radial bowing on forearm rotation in forearm fractures compared with healthy children. METHODS: A retrospective study was conducted on children aged 1-16 years old. Group 1 was children with history of diaphyseal forearm fractures, and group 2 was healthy children. Children in group 1 with ≤ 70° forearm pronation and/or ≤ 80° supination on affected side are defined as "case." In group 2, children with forearm pronation > 70° and/or supination > 80° are defined as "control." Radial bowing was measured on AP radiograph of the forearm; maximal radial bowing (MRB) and location of the maximal radial bowing (LMRB) were recorded. RESULTS: Total of 112 children were included (group 1 = 70, group 2 = 42). In group 1, there were 28 children with ≤ 70° forearm pronation and/or ≤ 80° forearm supination (case group). In group 2, there were 33 children with > 70° forearm pronation and > 80° forearm supination (control group). Mean age of case and control group was 11.08 ± 3.02 and 7.85 ± 3.93 years, respectively. Average MRB was 6.15 ± 1.93% and LMRB was 61.94 ± 9.41% in case group. In control group, average MRB was 7.23 ± 1.03% and LMRB was 62.08 ± 4.24%. There was statistically significant correlation between children with ≤ 70° forearm pronation and MRB (P = 0.034) compared with control group. Also, there was statistically significant correlation between children with ≤ 80° forearm supination and MRB (P = 0.023) compared with control group. For ROC curve analysis, MRB ≤ 6.84% showed the association with ≤ 70° forearm pronation (72.2% sensitivity and 73.8% specificity) and MRB ≤ 5.75% associated with ≤ 80° forearm supination (54.6% sensitivity and 84.9% specificity). CONCLUSIONS: Children with MRB ≤ 6.84% can result in ≤ 70° forearm pronation, and MRB ≤ 5.75% can be presented with ≤ 80° forearm supination.

Prognostic Factors in Recurrent Congenital Muscular Torticollis.

INTRODUCTION: Congenital muscular torticollis (CMT), primarily resulting from unilateral shortening and fibrosis of the sternocleidomastoid muscle. One of the common surgical complications is recurrent deformity. However, the associations between unipolar or bipolar release, age of the patient, and the recurrence of the disease are unclear. Therefore, the purpose of this study was to evaluate the factors associated with recurrence after surgery. MATERIALS AND METHODS: A retrospective review was performed in 47 patients who were diagnosed with CMT and had been treated surgically with unipolar or bipolar release between January 2007 and December 2015. Demographic data (sex, sides, surgical technique, age at time of surgery, period of follow-up, complications and recurrence) were recorded. RESULTS: Forty-seven patients with an average age of 8.7 years old at time of surgery. Twenty-six patients had right-sided muscular torticollis, while 21 had left-sided. The average follow-up time was 2 years (range, 2-4 years). The average age of unipolar release was 8.8 years old (range, 218 years old), while the average age of bipolar release was 8.7 years old (range, 2-13 years old). Recurrence occurred in 11 patients (9 in unipolar and 2 in bipolar release). Sex, side of deformity, type of surgery and age at time of surgery showed no statistically significant as a factor for recurrence rate, however recurrence of unipolar more than bipolar surgery was nearly two times revealing clinical significance. CONCLUSIONS: Sex, side of deformity, type of surgery and age at time of surgery were not associated with the recurrence deformity.
