The effect of prolonged immobilization on elbow range of motion in supracondylar humerus fractures treated with closed reduction and percutaneous pinning

Abstract

Aim: The purpose of this study was to evaluate the effect of prolonged immobilization on elbow range of motion in Gartland type III supracondylar humerus fractures treated with closed reduction and percutaneous pinning.

Material and Methods: In this retrospectively designed study, patients whose k-wires and cast were removed after sufficient callus tissue was visible were classified as Group A, and patients who had k-wires removed and arm casts used for more than 2 weeks prolonged were classified as Group B. All patients had Gartland type III supracondylar humerus fracture. Clinical outcomes of two patient groups were analyzed and compared.

Results: The final analysis included 72 patients. Group A consisted of 37 patients. Group B consisted of 35 patients. Group B had a significantly lower ROM than Group A in the second month (p< 0.001). Group B had a significantly lower ROM than Group A in the third month (p=0.004). There was no significant difference in ROM between Group A and Group B in the sixth (p=0.48) and twelfth months (p=0.54).

Discussion: In this study, there was no significant difference in ROM between patients who used long-arm casts for two weeks after their pins were removed and those who started mobilization early. Some patients may have to use long arm casts for a more extended period of time. However, it should be kept in mind that early rehabilitation reduces elbow contracture.
