Final answer:
The best next step after a patient's wrist pain persists despite initial treatment is to order a repeat x-ray to rule out a missed fracture, such as a scaphoid fracture which might not appear immediately on x-rays. If no fracture is evident, referral to physical therapy should be considered to facilitate recovery.
Step-by-step explanation:
After a patient presents with continuing wrist pain following a fall, with initial x-rays showing no fractures, the next course of action would be multifaceted. Since the initial conservative treatment has not led to improvement, it is reasonable to consider further diagnostic measures to ensure no fractures were missed, as a scaphoid fracture can sometimes only be seen on x-rays after some time due to initial swelling. Hence, option a, ordering a repeat x-ray to check for any fractures that may have been missed the first time, would be a prudent step. If the repeat x-ray also shows no fractures, then option b, referring the patient for physical therapy, might be recommended to aid in recovery through supervised exercises and therapies.
In cases where tendinitis is suspected or diagnosed, a splint and NSAIDs are common initial treatments. If these do not lead to improvement, escalating care with physical therapy is appropriate to ensure progress and prevent worsening of the condition. Prescribing stronger NSAIDs or continuing with only splinting and ice without re-evaluation or additional diagnostic follow-up, such as an MRI if indicated, could lead to further delays in healing and potential complications.
