Aka: Radial Nerve Injury at the Humerus, Saturday Night Palsy, Honeymooner's Wrist Drop, Sleep Paralysis, Crutch Palsy, Wrist Drop, Radial Nerve Compression, Radial Neuropathy, Radial Nerve Palsy- See Also
- Pathophysiology
- Radial Nerve tracks follows the spiral groove down the medial Humerus
- Causes
- Mid-shaft humerus Fracture
- Direct injury to the Radial Nerve as it lies in spiral groove
- Does not typically affect elbow extension (triceps)
- Axilla compression (Saturday Night Palsy, Crutch Palsy)
- Falling asleep with arm over the back of a chair or bench, often inebriated (Saturday Night Palsy)
- Results in loss of elbow extension (triceps) and a Wrist Drop
- Honeymooner's Wrist Drop
- Shoulder and upper arm compressed under the arm/body of their partner resulting in local compression
- Mid-shaft humerus Fracture
- Signs
- Weak elbow extension
- Occurs if Radial Nerve injury at the axilla
- Wrist Drop
- Weak wrist and digit extensors
- Sensory loss
- Dorsal hand numbness (including lateral 3.5 digits)
- Weak elbow extension
