Long arm splints are used in a variety of settings for immobilization of both bony and soft tissue injuries to the upper extremities. This type of splint provides immobilization to the elbow and the wrist. As a result, elbow flexion and extension and wrist flexion, extension, forearm supination/pronation can be restricted. Long arm splints are often the initial form of immobilization placed on an injured limb to accommodate soft tissue swelling before more definitive treatment with a cast or surgical fixation. This activity presents the indications for a long arm splint and highlights the role of the interprofessional team in the management of patients with arm pathology. Objectives: Identify the technique of a long arm splint. Describe the indications of a long arm splint. Review the complications of a long arm splint. Summarize interprofessional team strategies for improving care coordination and communication to advance the safe use of a long arm splint and improve outcomes.

Longarm splints are used in a variety of settings for immobilization of both bony and soft tissue injuries to the upper extremities. This type of splint provides immobilization to the elbow and the wrist. As a result, elbow flexion and extension and wrist flexion, extension, forearm supination/pronation can be restricted. Long arm splints are often the initial form of immobilization placed on an injured limb to accommodate soft tissue swelling before more definitive treatment with a cast or surgical fixation.[1][2][3]

As with any splinting technique, there are a few possible complications. Improperly padded splints can lead to skin breakdown. Splints that are wrapped too tight can lead to patient discomfort and possibly decrease perfusion to the extremity. During the curing process, splinting materials give off heat in an exothermic reaction. This heat can cause patient discomfort. Plaster can cause skin irritation if it makes direct contact with the skin. Over-padded splints can become too loose and inadequately immobilize an injury. Splints that are over aggressively molded can cause skin breakdown at the point of maximal pressure.

Long arm splints may be applied by many healthcare workers including therapists and orthopedic nurses.  Long arm splints are a valuable tool in the treatment of a variety of upper extremity injuries. This form of splinting can provide excellent immobilization while allowing for swelling that often accompanies acute injuries. Typically, a long arm splint is the initial form of immobilization. It typically is removed, and patients are transitioned into more definitive immobilization such as a cast. The practitioner needs to take time to become familiar with the materials and techniques needed to make a well-padded and molded splint that properly positions a patient to maintain a reduction and allow for soft tissue swelling. An interprofessional team consisting of emergency physicians, orthopedists, and emergency or orthopedic nurses will improve care and outcomes. [Level 5] Patient monitoring after splint placement is recommended. If the splint is too tight, it can lead to compartment syndrome, without devastating consequences.
