The Henry approach forearm represents a surgical technique gaining significant attention in orthopedic trauma care, particularly for managing complex fractures of the forearm. This method emphasizes a specific entry point along the medial aspect of the forearm, allowing for meticulous visualization of the fracture site while preserving critical neurovascular structures. By following the natural anatomical planes, surgeons can achieve stable fixation with reduced soft tissue disruption, which is fundamental to improving patient outcomes.
Understanding the biomechanics of the forearm is essential when considering the Henry approach. The radius and ulna function as a unified unit, requiring synchronized healing to restore full pronation and supination. The Henry approach provides an optimal corridor for accessing the radius, the bone most frequently requiring intervention, while simultaneously protecting the ulnar nerve and artery located medially. This balance between access and protection is the cornerstone of the technique’s design.
Historical Context and Evolution
Developed by Dr. Arthur Henry in the early 20th century, this approach was a response to the high rates of complications associated with more invasive procedures. Initially met with skepticism, the Henry approach gradually proved its efficacy in reducing nerve injuries and promoting faster recovery. Over the decades, modifications have been integrated, yet the fundamental principle of a direct, medial incision remains unchanged, demonstrating the robustness of the original concept.
Indications and Patient Selection
Surgeons utilize the Henry approach for specific fracture patterns where medial access is advantageous. Common indications include fractures of the distal third of the radius, particularly those involving the volar or dorsal aspects of the bone. It is also the preferred route for removing symptomatic hardware or addressing non-unions in this region. Careful patient selection is vital, as this approach is less suitable for highly comminuted fractures requiring extensive lateral exposure.
Distal radial fractures with volar displacement
Recurrent dorsal wrist ganglia requiring excision
Hardware irritation or infection at the distal radius
Non-unions in the distal radial shaft
Synovectomy for inflammatory conditions
Surgical Technique and Nuances
Executing the Henry approach demands precision and a thorough knowledge of anatomy. The procedure begins with a curvilinear incision along the medial border of the ulna, extending from the proximal forearm to the wrist crease. Subcutaneous tissues are dissected carefully to protect the basilic vein and the medial antebrachial cutaneous nerve. The investing fascia of the flexor muscles is then incised, revealing the flexor pronator mass, which is split along the fibers to minimize muscle damage.
Once the fracture site is exposed, the surgeon utilizes retractors to safeguard the median nerve and flexor tendons. The fracture is reduced under direct vision, ensuring anatomical alignment before applying internal fixation, such as a plate and screws. The technique’s strength lies in its ability to provide excellent exposure with minimal retractors, thereby reducing the risk of iatrogenic injury to the delicate structures within the carpal tunnel.
Recovery and Rehabilitation Protocols
Post-operative care following a Henry approach prioritizes early mobilization to prevent stiffness. Patients typically begin gentle range-of-motion exercises within the first week, focusing on wrist and finger movement. Weight-bearing or resistance activities are gradually introduced, guided by radiographic evidence of healing. Physical therapy plays a crucial role in restoring full function, with protocols tailored to the individual’s pain tolerance and healing progress.
Long-term outcomes are generally favorable, with high rates of union and restored function. The minimal scarring and preservation of muscle bulk contribute to superior cosmetic results compared to more lateral approaches. For the active patient or athlete, the Henry approach offers a reliable pathway back to pre-injury activity levels, combining effective fracture management with a commitment to biological preservation.
