The primary aim was to describe the epidemiology of the Holstein-Lewis humeral shaft fracture, its association with radial nerve palsy, and the outcome regarding recovery from the radial nerve palsy and fracture healing. The secondary aim was to analyze the long-term functional outcome.
Six major hospitals in Stockholm County.
Descriptive study. Retrospective assessment of radial nerve recovery and fracture healing. Prospective assessment of functional outcome.
Twenty-seven patients with a 12A1.3 humeral shaft fracture according to the OTA classification satisfying the criteria of a Holstein-Lewis fracture in a population of 358 patients with 361 traumatic humeral shaft fractures.
Nonoperative or operative treatment according to the decision of the attending orthopaedic surgeon.
Recovery of the radial nerve, fracture healing, and functional outcome according to the Short Musculoskeletal Function Assessment (SMFA).
The Holstein-Lewis humeral shaft fracture constitutes 7.5% of all humeral shaft fractures and was associated with an increased risk of acute radial nerve palsy compared with other types of humeral shaft fractures, 22% versus 8% (P
