A. It is a classical example of Neuropraxia
B. NEUROPRAXIA
- It is a physiological temporary reversible spontaneous conduction block leading to ‘Slow Conduction’
2. There is Transient Demyelination
(No need of Surgery as myelin can regenerate)
3. Here Axon/Sheath is intact
4. Recovery: Spontaneous, 100% (within 3-6 weeks)
5. Tinel’s Sign Negative
6. Eg of Neuraprexia:
• Sitting for too long
• Tourniquet Palsy
• Saturday Night Palsy
7. In Neuraprexia, nerve will spontaneously recover but in 6 weeks. BUT if the patient keeps his wrist flexed for 3-4 weeks, he will develop a Flexion deformity / Flexion Contracture / Flexion Stiffness. (So Option ‘A’ Wait & Watch is incorrect)
8. T/t: Dynamic Cock up splint (Option D) is applied to prevent contractures & deformities later
C. Saturday Night Palsy / Crutch Palsy:
- Due to Radial Nerve Palsy
- Occurs due to Compression of Radial Nerve in Radial groove while putting hand on chair or the crutch leading to ‘WRIST DROP’
- Commonly seen after alcohol intoxication
