Introduction and purpose: The most frequent neurological complication of humeral fractures is radial nerve palsy. Most patients with humeral fractures and radial nerve palsy recover with conservative treatment. But a small percentage of patients require surgical treatment; these are patients who show no clinical improvement of their nerve lesion after 3 months of conservative treatment, those with an open fracture, an associated vascular lesion, secondary radial palsy or patients who require open fracture osteosynthesis. The aim of this study is to assess and analyze humeral fractures with radial palsy that have required surgical treatment.

Materials and methods: A prospective pre and postoperative study with a protocol was carried out between 1999 and 2007 in which 28 patients with humeral fractures and radial palsy required surgical treatment. Of the patients studied 10 were women and 18 were men. Their ages varied from 18 to 74 years of age. As to the type of radial palsy, it was primary in 11 patients, secondary in 2 patients (included in the fracture callus) and postoperative in 15. Neurolysis was performed in 20 patients and fascicular grafts were used in 8.

Results: Time to fracture healing was 14.2 + 5.6 weeks. The period of radial nerve recovery was 7.2 + 5.7 months. Neurolysis was performed in 20 patients and fascicular grafts in 8. There were 20 complete recoveries, 4 incomplete but useful, in 4 cases there was no recovery and palliative surgery was subsequently performed.

Conclusions: Surgical treatment of humeral fractures with radial palsy is indicated in patients who show no clinical improvement of their nerve lesion after 3 months of conservative treatment, those with an open fracture, an associated vascular lesion, secondary radial paralysis or in patients who require an open fracture osteosynthesis. Functional recovery rates are high if surgery is carried out during the appropriate period of time. Treatment is neurolysis or fascicular grafts. Palliative surgery is reserved for cases in which complete recovery is not achieved.
