Shared decision-making (SDM) is a patient-centered approach where medical professionals collaborate with patients to make treatment decisions. In this case report, we describe an 88-year-old woman who suffered a traumatic atlas fracture, and surgical treatment was initially recommended. However, she tended to endorse conservative treatment and consulted her family physician. Her family physician conducted a thorough review of medical literature and explained the risks of surgical and non-surgical treatments. Finally, a rigid collar was decided. Subsequent follow-up of the patient showed no neurological deficits, and she regained neck mobility. This case reveals that conservative treatment with rigid collars is a safe and effective option for stable atlas fractures. Family physicians play a crucial role in consolidating medical information and facilitating SDM, which respects patient's preferences and values, promotes information exchange between medical staff and patients, and makes the best treatment plan together.
