One Versus 3-Week Immobilization Period for Nonoperatively Treated Proximal Humeral Fractures: A Prospective Randomized Trial

Abstract

Background: There is no consensus on the duration of immobilization for nonoperatively treated proximal humeral fractures (PHFs). The main objective of the study was to determine the differences in pain between PHFs that were treated nonoperatively with 3-week immobilization and those treated with 1-week immobilization.

Methods: A prospective randomized trial was designed to evaluate whether the immobilization time frame (1-week immobilization [group I] versus 3-week immobilization [group II]) for nonoperatively treated PHFs had any influence on pain and functional outcomes. Pain was assessed using a 10-cm visual analog scale (VAS) that was administrated 1 week after the fracture, at 3 weeks, and then at the 3, 6, 12, and 24-month follow-up. The functional outcome was evaluated using the Constant score. To assess the functional disability of the shoulder, a self-reported shoulder-specific questionnaire, the Simple Shoulder Test (SST), was used. The Constant score and the SST were recorded at the 3, 6, 12, and 24-month follow-up. Complications and secondary displacement were also recorded.

Results: One hundred and forty-three patients were randomized, and 111 (88 females and 23 males) who had been allocated to group I (55 patients) or group II (56 patients) were included in the final analysis. The mean age of the patients was 70.4 years (range, 42 to 94 years). No significant differences were found between the 2 groups in terms of pain as measured with the VAS at any time point (1 week [5.9 versus 5.6; p = 0.648], 3 weeks [4.8 versus 4.1; p = 0.059], 3 months [1.9 versus 2.4; p = 0.372], 6 months [1.0 versus 1.2; p = 0.605], 1 year [0.65 versus 0.66; p = 0.718], and 2 years [0.63 versus 0.31; p = 0.381]). No significant differences were found in the Constant score or SST score at any time point. No significant differences were noted in the complication rate.

Conclusions: Short and long periods of immobilization yield similar results for nonoperatively treated PHFs, independent of the fracture pattern. These fractures can be successfully managed with a short immobilization period of 1 week in order to not compromise patients' independence for an overly extended period.

Level of evidence: Randomized controlled trial Level II. See Instructions for Authors for a complete description of levels of evidence.
