Final answer:
Controlled Active Range of Motion (AROM) exercises can be initiated for a healing distal radius fracture when sufficient stability and evidence of healing are present, which is generally a few weeks post-injury but varies based on individual circumstances and must be guided by a physician's advice.
Step-by-step explanation:
The student's question pertains to the rehabilitation protocol following a distal radius fracture, specifically, the timing for the initiation of controlled Active Range of Motion (AROM) exercises if the fracture is healing secondarily. Secondary bone healing involves the creation of a callus, gradual bridging of the fracture, and eventual remodeling to restore bone strength and shape. Controlled AROM exercises should be introduced cautiously and according to a physician's guidance, typically when there is sufficient evidence of fracture healing and stability to prevent disruption. Normally, this might occur a few weeks after the injury, but the exact timing can vary based on individual circumstances, including the nature of the fracture and the patient's overall health. It is essential that an Occupational Therapist Registered (©OTR) closely monitors the client's pain levels, range of motion, and functional use of the wrist and hand to ensure that the rehabilitation program does not compromise the healing process.
