Abstract
Background
Several studies have suggested that excellent therapeutic outcomes can be achieved with conservative treatment of proximal humeral epiphyseal fractures in patients younger than 11 years old; however, the outcomes of conservative treatment for children older than 11 years are controversial. To address this problem, this study compared outcomes of conservative treatment for proximal humeral epiphyseal fractures in pediatric patients of different ages.
Methods
The patients were divided into two groups for comparative purposes based on age. Group I consisted of 34 patients who were less than 11 years old (average age: 5 years) and group II included 21 patients who were 11 years of age or older (average age: 14 years). 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 2 years, patients were assessed by an interview and a detailed physical examination including the assessment of shoulder function using the Constant-Murley score.
Results
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 group I and group II 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.
Conclusion
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 a difference 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.
Zusammenfassung
Hintergrund
Mehrere Studien haben gezeigt, dass durch die konservative Behandlung proximaler humeraler epiphysärer Frakturen bei Patienten <11 Jahren exzellente therapeutische Ergebnisse erzielt werden können. Jedoch sind die Ergebnisse der konservativen Behandlung bei Kindern >11 Jahren kontrovers. Um dieses Problem zu adressieren, verglich man in dieser Studie die Ergebnisse der konservativen Behandlung proximaler humeraler epiphysärer Frakturen bei Kindern unterschiedlichen Alters.
Methoden
Gruppe I bestand aus 34 Patienten, die jünger als 11 Jahre waren (Durchschnittsalter 5 Jahre), und Gruppe II schloss 21 Patienten ein, die 11 Jahre oder älter waren (Durchschnittsalter: 14 Jahre). Die Patienten beider Gruppen erhielten eine konservative Behandlung sowie eine Follow-up-Untersuchung, bei der sie mittels Röntgenaufnahmen untersucht wurden, um Deformität, Frakturheilung und den Reduktionsverlust zu beurteilen. Beim letzten Follow-up nach 2 Jahren wurden die Patienten mittels eines Interviews und einer detaillierten körperlichen Untersuchung bewertet, einschließlich der Beurteilung der Schulterfunktion mittels Constant-Murley-Score.
Ergebnisse
Es gab keine signifikanten Unterschiede in der Klassifikationsskala für Varusdeformität zwischen den 2 Gruppen (p > 0,05) nach der sofortigen Röntgenaufnahme nach Reduktion. Jedoch gab es signifikante Unterschiede in der Klassifikationsskala für Varusdeformität zwischen Gruppe I und Gruppe II beim 2‑Jahres-Follow-up (p < 0,05). Hinsichtlich des Constant-Murley-Scores und der Armlängendiskrepanz (p > 0,05) wurden zwischen den beiden Gruppen bei der letzten Follow-up-Untersuchung keine signifikanten Unterschiede festgestellt.
Schlussfolgerung
Im Allgemeinen zeigten die Ergebnisse, dass die mittels Röntgenaufnahmen erfassten Outcomes sowohl bei älteren als auch bei jüngeren Kindern nach einer sofortigen Röntgenaufnahme nach Reduktion vergleichbar waren. Im Langzeit-Follow-up wurde ein Unterschied zwischen den beiden Gruppen festgestellt, und dass Angulationsgrad und Dislokation mit den Behandlungsergebnissen älterer Kinder assoziiert sein könnten. Daher sollten diese Faktoren bei der Behandlung und Evaluation der Ergebnisse älterer Kinder berücksichtigt werden.
