Carpal Tunnel Syndrome (CTS) results from the compression of the median nerve as it travels through a narrow passageway in the wrist. This compression causes symptoms like numbness, tingling, and weakness, particularly in the thumb, index, middle, and part of the ring finger. While initial management involves non-surgical approaches like wrist splinting or corticosteroid injections, surgery is often necessary when these methods fail.
The surgical procedure, known as carpal tunnel release, involves cutting the transverse carpal ligament, which forms the roof of the tunnel, to relieve pressure on the median nerve. This procedure is reserved for severe or persistent cases to prevent permanent nerve damage and restore hand function.
The Path to Diagnosis
The path to surgery begins with non-surgical medical professionals who manage the condition’s early stages. A Primary Care Physician (PCP) often assesses symptoms and initiates conservative treatments, such as activity modification and splinting. If symptoms persist, the patient is referred to a specialist for definitive diagnostic testing.
Neurologists confirm the diagnosis by performing electrodiagnostic studies, specifically nerve conduction studies (NCS) and electromyography (EMG). These tests measure the speed and strength of electrical signals, quantifying the degree of compression and nerve damage.
Physical Medicine and Rehabilitation (PM&R) specialists also determine the necessity for surgery by assessing the failure of non-surgical interventions. They act as gatekeepers, referring the patient to a surgeon only when objective data indicates nerve decompression is required.
Primary Surgical Specialists
Once surgery is determined, three primary specialties are qualified to perform carpal tunnel release: Orthopedic Surgeons, Plastic Surgeons, and Neurosurgeons. Each specialty is trained to address the anatomical components of the hand and wrist, though their foundational training differs.
Orthopedic Surgeons
Orthopedic Surgeons, particularly those focused on the upper extremity, are often the most common specialists. Their residency training centers on the musculoskeletal system, giving them expertise in the bones, tendons, and ligaments that form the carpal tunnel structure. They are well-equipped to handle the anatomical release of the ligament.
Plastic Surgeons
Plastic Surgeons frequently perform hand surgery, including carpal tunnel release. Their extensive training in delicate soft tissue handling and reconstructive procedures makes them adept at managing the skin and intricate structures around the nerve.
Neurosurgeons
Neurosurgeons also perform carpal tunnel release, as their specialization focuses on the nervous system, including peripheral nerves like the median nerve. Their expertise in nerve pathology and decompression techniques makes them suitable for this procedure. The choice of surgeon often depends on local practice patterns and the individual surgeon’s specialized training.
Specialized Training and Expertise
While multiple surgical specialties are qualified, the most important factor in selecting a surgeon is subspecialty training and a high volume of experience in hand surgery. The standard for focused expertise is the completion of a one-year, accredited Hand Surgery Fellowship following the primary surgical residency. This additional training provides an in-depth focus on the complex anatomy and various conditions affecting the entire hand and upper extremity.
Surgeons who have completed this fellowship are eligible to obtain the Subspecialty Certificate in Surgery of the Hand, which was formerly known as the Certificate of Added Qualifications (CAQ) in Hand Surgery. This certification, administered by a joint committee of the American Boards of Orthopaedic Surgery, Plastic Surgery, and Surgery, signifies a recognized level of expertise beyond general board certification. Obtaining this certificate requires passing a rigorous examination and demonstrating significant experience through a submitted case log.
Patients should prioritize a surgeon who holds this subspecialty certification, regardless of whether their initial residency was in orthopedics, plastic surgery, or general surgery. The surgeon’s volume of carpal tunnel procedures and specific experience with the chosen technique, such as open or endoscopic release, is also a relevant consideration. Ultimately, the best results are linked to the dedicated, specialized training focused on the delicate work of the hand.
