About Complete BPI

A complete brachial plexus injury affects all five roots from C5 to T1, leaving the arm flail and insensate. The injury usually follows high-energy trauma, particularly motorcycle crashes. Early recognition is critical because acute repair within months gives the best chance of reanimating muscles before motor end-plates lose receptivity to incoming nerve fibres.

Initial assessment combines a careful history, physical examination of every muscle group, and dedicated imaging. MRI of the cervical spine and brachial plexus highlights root avulsions, pseudomeningoceles and post-ganglionic injuries. Nerve conduction studies and EMG add functional information, while CT myelography may be requested in selected cases. Together these guide the surgical roadmap.

Surgery is staged around priority functions. Shoulder reanimation often uses spinal accessory to suprascapular nerve transfer, sometimes combined with phrenic or intercostal transfers. Elbow flexion is restored using transfers to the musculocutaneous nerve. When intraplexal donors are unavailable, contralateral C7 transfer becomes a powerful option to provide a single strong donor for distal targets.

Free functioning muscle transfer, typically gracilis, may be used in extensive avulsions to provide elbow flexion or finger function powered by intercostal or contralateral C7 nerves. Sensory restoration on the lateral hand is addressed where possible to protect the limb from injury. The plan is individualised to the patient's age, occupation and overall medical fitness.

Postoperative care includes pain control, sling immobilisation and early protected mobilisation of unaffected joints to prevent stiffness. Smoking is strictly discouraged as it impairs nerve regeneration. Regular reviews over the first year monitor signs of reinnervation, and physiotherapy is intensified once muscles begin to respond. Splints and electrical stimulation are used as adjuncts where appropriate.

Outcomes depend on injury pattern, time to surgery, age and rehabilitation. Most patients gain useful elbow flexion and shoulder stability, with hand function more limited in complete injuries. We discuss expectations openly, plan secondary procedures such as tendon transfers or joint fusions when needed, and provide structured follow-up so progress is reviewed and supported through the entire recovery journey.

What to expect

• Detailed clinical and imaging assessment of all five nerve roots
• Nerve transfers prioritising shoulder stability and elbow flexion
• Free functioning muscle transfer where intraplexal donors are inadequate
• Sensory transfers to protect the hand where feasible
• Structured pain control and early protected mobilisation
• Long-term physiotherapy with periodic surgical review

Recovery

• Sling protection and gentle range-of-motion exercises in the first weeks
• Reinnervation typically appears between six and twelve months
• Active strengthening introduced once muscles begin to respond
• Strict avoidance of smoking and other factors that impair nerve healing
• Periodic review for possible secondary tendon or muscle transfers
