EMERGENCY:Traumatic brachial plexus injury from a road accident with complete arm paralysis requires urgent referral to a specialist brachial plexus surgery centre. Surgical timing is guided by injury pattern, spontaneous recovery, and serial clinical and electrophysiological assessment. Delays beyond 12–18 months significantly reduce the options and outcomes for nerve repair. —call040-46324365immediately — 24 hours, 7 days— 24/7
Brachial Plexus Injury in Hyderabad: The Arm That Cannot Move After the Accident — Avulsion, Rupture, Nerve Grafting, and Early Specialist Assessment at KIMS
Same-pathway CT myelography and 3T MRI brachial plexus mapping of avulsion vs rupture, NCS/EMG, chest X-ray with diaphragm screening, nerve grafting with sural nerve, nerve transfer (spinal accessory, intercostal, contralateral C7), tendon transfer for late reconstruction, and physiotherapy for obstetric Erb's palsy — coordinated by the KIMS Neuroscience team at KIMS Neuroscience, Secunderabad, Hyderabad.
Brachial plexus injury is traumatic damage to the network of nerves (C5, C6, C7, C8, T1) that control the entire arm. In India, two-wheeler road traffic accidents are by far the most common cause: lateral neck flexion away from a depressed shoulder produces traction that either tears the nerve roots from the spinal cord (avulsion, pre-ganglionic) or ruptures them distal to the dorsal root ganglion (post-ganglionic). The distinction is the single most important question in BPI management. CT myelography shows pseudomeningoceles in avulsion; MRI shows rupture sites and neuromas. Sensory action potentials are PRESERVED on NCS in avulsion (the DRG is intact distal to the injury) but ABSENT in rupture — this electrophysiological finding determines surgical strategy. Avulsion requires nerve transfer (neurotisation: CN XI to suprascapular, intercostals to musculocutaneous, contralateral C7 for total avulsion); rupture allows nerve grafting. Chest X-ray screens for raised hemidiaphragm (phrenic nerve palsy from C3–C5 involvement) which changes the surgical plan. Surgical timing is not a single rigid 3–6 month window — it is guided by injury pattern, the presence or absence of spontaneous recovery, and findings on serial clinical and electrophysiological assessment. Early referral to a specialist centre is essential so that serial assessment can be performed and surgery timed appropriately for each patient.
- Surgical timing: early referral, serial assessment, individualized decision
- Brachial plexus injury requires urgent specialist referral. Surgical timing is not a single rigid 3–6 month deadline — it depends on injury pattern (complete avulsion vs partial), whether spontaneous recovery is occurring, and serial clinical and electrophysiological findings at 6–8 weeks, 3 months, and 6 months. Denervated muscle quality does decline over time, making prolonged delays harmful, but the timing decision is individualized. Beyond 12–18 months, even successful nerve repair cannot reinnervate dead muscle. MRI brachial plexus + CT myelography at KIMS within 4–6 weeks of injury defines the surgical plan.
- Avulsion vs rupture — the critical distinction
- Avulsion (pre-ganglionic): nerve root torn from the spinal cord. CT myelography shows pseudomeningoceles. Sensory action potentials PRESERVED on NCS (DRG intact distal to avulsion). Cannot be repaired by grafting — requires nerve transfer (neurotisation). Rupture (post-ganglionic): nerve torn distal to the DRG. SAPs absent. Can be repaired by nerve grafting.
- Phrenic nerve screening — change the surgical plan
- Chest X-ray for a raised hemidiaphragm in every BPI. Phrenic nerve palsy (from C3–C5 involvement) means the intercostal-to-musculocutaneous nerve transfer is high-risk (compromised inspiratory reserve). Surgical strategy switches: use spinal accessory or contralateral C7 instead.
- Nerve transfers at KIMS
- Spinal accessory (CN XI) to suprascapular nerve = shoulder abduction · Intercostal nerves (ribs 3–5) to musculocutaneous nerve = elbow flexion · Contralateral C7 (from the uninjured side) for total avulsion · Oberlin transfer (ulnar nerve fascicle to biceps motor branch) for upper trunk injury
- Sensory action potentials — the diagnostic key
- On NCS, intact SAPs in an anaesthetic limb prove the dorsal root ganglion is alive and distal to the lesion = AVULSION (pre-ganglionic). Absent SAPs = the lesion is distal to the DRG = RUPTURE (post-ganglionic, can be grafted). This single electrophysiological finding determines surgical strategy.
- Nalgonda motorcyclist context
- The typical KIMS BPI case: a young male from rural Telangana (Nalgonda, Mahabubnagar, Khammam) thrown from a two-wheeler, lateral neck flexion away from the depressed shoulder. Erb point traction (C5–C6 upper trunk) is most common; total plexus avulsion occurs in high-speed impacts. RTA cases referred within 4–6 weeks have the best outcomes.
- Erb vs Klumpke vs total
- Erb's palsy (C5–C6, upper plexus): waiter's tip posture (arm adducted, internally rotated, elbow extended, forearm pronated) · Klumpke's palsy (C8–T1, lower plexus): claw hand + Horner syndrome (ptosis, miosis, anhidrosis from T1 sympathetic loss) · Total plexus avulsion (C5–T1): flail anaesthetic arm

About This Condition
Brachial Plexus Injury at a Glance
The essential facts that shape how brachial plexus injury is recognised and managed at KIMS — the anatomy of the C5–T1 network, why motorcycle accidents dominate adult cases in India, the critical avulsion vs rupture surgical distinction, and the upper, lower, and total plexus injury patterns.
What the brachial plexus is
The brachial plexus is the network of nerve roots (C5, C6, C7, C8, T1) that emerge from the cervical spine and form the major nerves supplying the arm: the axillary nerve (shoulder abduction), musculocutaneous nerve (elbow flexion), radial nerve (wrist/finger extension), median nerve (forearm pronation, hand grip, thumb/index sensation), and ulnar nerve (intrinsic hand muscles). The brachial plexus is organised into roots, trunks, divisions, cords, and terminal branches. Injury at any level produces a predictable pattern of arm weakness and sensory loss.
Mechanism in India — motorcycle accidents
The most common cause of traumatic adult brachial plexus injury in India is a high-speed motorcycle crash in which the rider falls and the head and shoulder are forcefully separated — the neck is pushed laterally away from the shoulder. This violent lateral flexion of the neck stretches or tears the C5–T1 nerve roots from their spinal cord attachment. India's young male motorcycle-riding population and high road accident rate make traumatic brachial plexus injury one of the most common devastating peripheral nerve injuries at KIMS.
Avulsion vs rupture — the most important surgical distinction
Root avulsion: the nerve root is torn directly from the spinal cord. Avulsed roots cannot be repaired — there is no proximal nerve stump to graft to. Confirmed by CT myelography (pseudomeningocele formation at the avulsed root level). Root rupture: the nerve is torn at some point along its extraspinal course, leaving a proximal stump intact. Ruptures can be repaired with nerve grafts. At KIMS, CT myelography and MRI brachial plexus are performed on all adult traumatic brachial plexus patients to map the avulsion/rupture pattern before surgical planning.
Upper, lower, and total plexus injuries
Upper plexus injury (C5–C6, Erb's palsy): shoulder abduction, elbow flexion, and forearm supination weakness — the arm hangs medially rotated with the elbow extended (waiter's tip posture). Lower plexus injury (C8–T1, Klumpke's palsy): intrinsic hand muscle weakness (claw hand), and Horner syndrome (T1 sympathetic fibres avulsed). Total plexus injury: complete flail arm — no movement from shoulder to fingertips, dense sensory loss throughout the limb.

The Motorcyclist and the Window That Was Closing
A 24-year-old man from Nalgonda is brought to KIMS 10 weeks after a motorcycle accident on the Hyderabad–Vijayawada highway. He was thrown from his motorcycle at high speed and landed on his right shoulder and neck. He was treated at a local hospital for clavicle fracture and road rash. Nobody examined his arm function carefully in the acute period. At 10 weeks, the right arm hangs completely limp at his side. He cannot abduct the shoulder, flex the elbow, or move the wrist. The right hand has no grip. Dense numbness from the shoulder to the fingertips. Horner syndrome present on the right: ptosis, miosis, and anhidrosis on the right face.
At KIMS: complete right brachial plexus injury confirmed (flail, anaesthetic arm). MRI brachial plexus and CT myelography: pseudomeningoceles at C8 and T1 levels (confirming root avulsion at C8–T1); C5, C6, and C7 roots show rupture with intact proximal stumps visible on MRI. NCS/EMG: no motor units recordable in any right arm muscle; sensory action potentials absent for median, ulnar, and radial nerves. Assessment: C5–C7 ruptures (repairable) + C8–T1 avulsions (non-repairable by grafting).
Surgical planning at KIMS by the KIMS Neuroscience team: nerve grafting using sural nerve grafts (harvested from the calf) to bridge the C5–C6 rupture gaps, aiming to restore shoulder abduction and elbow flexion. Spinal accessory nerve (CN XI) transferred to the suprascapular nerve (shoulder abduction). Intercostal nerve transfer (using motor intercostal nerves of ribs 3–5) to the musculocutaneous nerve (elbow flexion target). The C8–T1 avulsions cannot be repaired — hand function will depend on later tendon transfer planning.
At 6-month post-surgery review: early signs of shoulder elevation returning. At 12 months: shoulder abduction grade 2–3/5; elbow flexion grade 2/5 beginning. The recovery is incomplete — the hand will never be normal — but the difference between a flail arm and a useful arm with shoulder and elbow function is the difference between employment and dependency.

040-44885000Emergency — acute traumatic plexus injury: 040-46324365Clinical Patterns of Brachial Plexus Injury
The clinical profile of brachial plexus injury at KIMS spans the classical upper plexus (Erb's palsy) waiter's tip arm, the rarer lower plexus (Klumpke's palsy) claw hand with Horner syndrome, the devastating total plexus flail arm, and the obstetric (birth) Erb's palsy that most often recovers spontaneously.
Upper plexus injury (C5–C6) — Erb's palsy
The classic upper brachial plexus injury pattern: loss of shoulder abduction (deltoid, supraspinatus), elbow flexion (biceps, brachialis), and forearm supination. The arm hangs in the characteristic waiter's tip posture — adducted, medially rotated at the shoulder, extended at the elbow. Sensation is reduced over the outer arm and lateral forearm. In birth-related Erb's palsy, spontaneous recovery occurs in 80–90% of infants within 3–6 months. In adult traumatic Erb's palsy, surgical reconstruction is required for persistent paralysis.
Lower plexus injury (C8–T1) — Klumpke's palsy
The rarer lower brachial plexus pattern: intrinsic hand muscle weakness (all the small hand muscles), wrist flexor weakness, and sensory loss in the ring and little fingers and the medial forearm. Shoulder and elbow function are preserved. Horner syndrome (ptosis, miosis, anhidrosis on the ipsilateral face) occurs when T1 is avulsed. Horner syndrome in a brachial plexus injury is a clinical sign of T1 avulsion — an unrepairable level.
Total plexus injury — the flail arm
Complete C5–T1 involvement: no movement at any joint from shoulder to fingertips; dense sensory loss throughout the arm; the arm is warm, dependent, and oedematous from vascular dysregulation. Total brachial plexus avulsion is the most devastating peripheral nerve injury compatible with limb survival. Surgical goals shift to functional reconstruction: restoring at minimum elbow flexion and some hand grasp through nerve transfers and tendon transfers.
Birth brachial plexus palsy (obstetric palsy)
From excessive lateral traction during a difficult delivery (shoulder dystocia, forceps delivery, large-for-dates baby). Most commonly affects C5–C6 (Erb's palsy pattern). Most infants (80–90%) recover spontaneously by 3 months. Persistent deficits at 3–6 months indicate more severe injury requiring specialist assessment. At KIMS, physiotherapy is primary; surgery (nerve grafting) is considered for infants with no recovery by 3–6 months of age.
Diagnosis at KIMS
Diagnosis at KIMS — CT Myelography, MRI Brachial Plexus, NCS/EMG & Diaphragm Screening
Brachial plexus injury is mapped at KIMS with a coordinated imaging and physiological workflow that distinguishes avulsion from rupture and informs the surgical plan :
CT myelography — avulsion diagnosis
Intrathecal contrast injected by lumbar puncture opacifies the spinal canal; CT imaging shows pseudomeningoceles (CSF-filled pouches at avulsed root levels). The most reliable method for diagnosing root avulsion. At KIMS, CT myelography is performed in all adult traumatic brachial plexus injuries to map the avulsion/rupture pattern.
MRI brachial plexus — extraspinal anatomy
High-resolution MRI (3T with dedicated plexus sequences) visualises the roots, trunks, divisions, and cords; identifies rupture sites (nerve discontinuity, neuroma formation); and assesses the muscle targets for potential reinnervation. MRI and CT myelography are complementary and both performed at KIMS.
NCS/EMG — physiological assessment
Confirms denervation of specific muscles; distinguishes complete from incomplete injuries; identifies the level of injury. Key finding: in pre-ganglionic avulsion, sensory nerve action potentials are preserved despite clinical sensory loss (the dorsal root ganglion is intact distal to the avulsion); in post-ganglionic rupture, sensory action potentials are absent. Serial NCS/EMG tracks reinnervation after surgery.
Chest X-ray and diaphragm screening
A raised hemidiaphragm (phrenic nerve palsy from C3–C5) indicates a proximal C5 root avulsion and limits the use of the C5 root for repair. The presence of a raised hemidiaphragm changes the surgical strategy at KIMS.
Treatment
Treatment at KIMS
The KIMS brachial plexus surgery programme is built around four integrated management areas — the 3–6 month surgical window, nerve grafting for root ruptures, nerve transfer (neurotisation) for avulsions, and tendon and muscle transfer for late reconstruction — each chosen by the avulsion/rupture pattern, the time since injury, and the highest-priority functional targets.
Surgical window, nerve grafting, nerve transfer & tendon transfer at KIMS
Individualized Surgical Timing — Based on Injury Pattern and Serial Assessment: There is no single rigid 3–6 month surgical window for brachial plexus reconstruction. Surgical timing is guided by: (1) Injury pattern: complete avulsions with no chance of spontaneous recovery may be addressed earlier; incomplete injuries require a period of serial assessment to determine whether spontaneous recovery is occurring. (2) Spontaneous recovery: serial clinical examination and NCS/EMG at 6–8 weeks, 3 months, and 6 months tracks whether recovery is progressing. If reinnervation signs appear on EMG, surgery may be deferred or modified. (3) Muscle quality: denervated muscle quality declines with prolonged delay — making early specialist referral essential so the timing decision is made by the specialist team and not delayed by late referral. Surgery beyond 12–18 months significantly limits options; nerve repair shifts to tendon transfer at that stage. At KIMS, every patient with traumatic brachial plexus injury is referred for specialist assessment early, so that serial monitoring and appropriately-timed surgery can be planned.
Nerve Grafting — for Root Ruptures: When a nerve root has ruptured (not avulsed), the proximal and distal stumps are bridged with autologous nerve graft — typically the sural nerve from the calf. The graft acts as a scaffold for axon regrowth. Recovery: axon regeneration at 1 mm per day from the repair site to the target muscle. Elbow flexion (biceps) is the highest-priority target: approximately 25–30 cm from the C5–C6 plexus, so recovery takes 12–18 months after surgery.
Nerve Transfer (Neurotisation) — for Avulsions: When the nerve root has been avulsed (no proximal stump), a donor nerve from outside the injured plexus drives reinnervation. Common donor nerves at KIMS — Spinal accessory nerve (CN XI): transferred to suprascapular nerve for shoulder abduction; the XI nerve can be sacrificed with minimal morbidity. Intercostal nerves (ribs 3–5): transferred to musculocutaneous nerve for elbow flexion; the patient relearns elbow flexion by trying to breathe in — the cortical map eventually reorganises to consciously control the arm movement. Contralateral C7 root: the C7 root of the intact opposite arm used as a donor for the totally avulsed plexus, producing some recovery of wrist and finger extension; used for total plexus avulsions.
Tendon and Muscle Transfer — Late Reconstruction: When nerve regeneration cannot restore a specific function (particularly hand intrinsic muscles, too far from the plexus for axons to reach in time), tendon transfers redirect existing functional muscle-tendon units to perform the paralysed movement. Late reconstruction (12–36 months post-injury) at KIMS includes: latissimus dorsi transfer for elbow flexion; trapezius transfer for shoulder abduction; wrist tenodesis and intrinsic reconstruction for hand function.
