Radial nerve palsy following humeral shaft fractures
Regarding radial nerve palsy following fractures of the humeral shaft.
1.The Holstein–Lewis fracture — a spiral fracture of the distal third of the humeral shaft — has a higher rate of associated radial nerve palsy than other humeral-shaft fracture patterns.
2.In closed fractures, neuropraxia is the most common nerve injury; in open fractures, neurotmesis is more common.
3.Iatrogenic radial nerve palsy occurs more commonly after posterior than anterolateral approach for humeral-shaft open reduction and internal fixation.
4.Spontaneous recovery of nerve function is often observed around 7 weeks, with full recovery by approximately 6 months.
5.Surgical exploration is indicated in open fractures and in closed fractures that do not show improvement within 4–6 months.
