Preventing Unnecessary Surgery in Patients Presenting for Orthopedic Spine Surgery: Literature Review and Case Series

Almost 40% of patients who have been diagnosed with amyotrophic lateral sclerosis (ALS) may have been misdiagnosed. Some of these patients may have undergone surgical procedures to address symptoms that could have actually be early indications of ALS.Up to 40% of patients diagnosed with amyotrophic lateral sclerosis (ALS) have received an incorrect diagnosis, a number undergo surgical treatment for signs and symptoms that can be attributed to early manifestations of ALS. Initial presentation of ALS is elusive and is often mistaken for other disorders originating from the cervical spine such as cervical radiculopathy or myelopathy. Such incorrect diagnoses often display symptoms that fall within the scope of an orthopedic spine surgeon, who can remedy said diagnoses. Given that a diagnosis of ALS is grave, it is crucial to establish a definitive diagnosis quickly, without unnecessary surgery. The objective of this series is to highlight patients who were referred by other physicians for spine surgery to remedy potential side effects of cervical myelopathy but were ultimately diagnosed with ALS. Case 1: A 46-year-old Caucasian woman with carpal tunnel syndrome and cervical intervertebral disc degeneration. Case 2: A 77-year-old African American man with a history of arthritis, GERD, a herniated disc, claw hand, hypertension, prostate disease, and general weakness. Case 3: A 74-year-old Caucasian woman with a background history of hypertension, dyslipidemia, hypothyroidism, osteopenia, and foot drop. In orthopedic spine surgery, ALS could be an easily misdiagnosed disease, which can be mistaken for cervical spondylosis, cervical radiculopathy, cervical myelopathy, lumbar radiculopathy, and lumbar myelopathy; it is of note to be aware of how ALS may initially present. It is imperative for the orthopedic spine surgeon to consider ALS with patients presenting with progressive unilateral/bilateral upper extremity weakness.
