You will be provided with the titles and abstracts of a collection of medical RCT reports studying a clinical question -- for instance, the efficacy of an intervention on some medical outcome. Please write a few sentences synthesizing the findings of these reports, which could serve as a conclusion section for a systematic review article. Your response should not include any other text. The RCT reports are below.



Title 1:
Hyperextension injuries of the PIP finger joint. Comparison of early motion and immobilization.
Abstract 1:
In a prospective study of traumatic lesions of the volar fibrocartilage of the PIP joint, 56 patients were randomized to treatment by immobilization for 3 weeks and 56 patients, to purely analgetic treatment without immobilization. Seventy-eight patients were reexamined 6 months later and 77 patients, in a follow-up study 2-3 years after the injury. No difference was found between the two groups with respect to subjective complaints or objective signs.


Title 2:
[Hyperextension injuries of the volar fibrocartilage in the proximal interphalangeal joints of the fingers].
Abstract 2:
nan
There is insufficient evidence from trials testing the need for, and the extent and duration of, immobilisation to inform on the key conservative management decisions for treating hyperextension injuries of the proximal interphalangeal joints.
