Functional results following fractures of the proximal humerus. A controlled clinical study comparing two periods of immobilization.

In order to compare 1 and 3 weeks of immobilization following proximal humeral fractures a prospective controlled trial was performed in 85 patients. Clinical follow-up according to the Neer assessment system was done after 1, 3, 6, 12, and 24 months. One week of immobilization resulted in a better total score due to less pain during the first 3 months. After 6 months no difference in pain, function, or mobility was found and no further recovery of shoulder function was seen after 12 and 24 months.
