Comparison of conservative treatment outcomes for proximal humeral epiphyseal fractures in patients of different ages.

Abstract

Several studies have suggested that excellent therapeutic outcomes can be achieved with conservative treatment of proximal humeral epiphyseal fractures in patients younger than 11years old; however, the outcomes of conservative treatment for children older than 11years are controversial. To address this problem, this study compared outcomes of conservative treatment for proximal humeral epiphyseal fractures in pediatric patients of different ages. The patients were divided into two groups for comparative purposes based on age. GroupI consisted of 34patients who were less than 11years old (average age: 5years) and groupII included 21patients who were 11years of age or older (average age: 14years). Patients in both groups underwent conservative treatment and follow-up examination, where they first were examined with X‑radiography for assessment of deformity, fracture union and loss of reduction. At the final follow-up after 2years, patients were assessed by an interview and adetailed physical examination including the assessment of shoulder function using the Constant-Murley score. There were no significant differences in the grading scale of varus deformity between the two groups (P > 0.05) after immediate postreduction X‑radiography; however, there were significant differences in the grading scale of varus deformity between groupI and groupII at the 2‑year follow-up (P < 0.05). There were no significant differences between the two groups with respect to the Constant-Murley score and arm length discrepancy (P > 0.05) at final follow-up examinations. In general, the results suggested that the outcomes, as measured with radiographs, for both older and young children were comparable after immediate postreduction roentgenograms. For long-term follow-up there was adifference between the two groups and the degree of angulation and displacement might be associated with treatment outcomes for older children. Thus, these factors should be considered when treating and evaluating the outcomes for older children.
