Background:
The authors modified the anterolateral approach for Holstein-Lewis humeral shaft fractures using a plating technique to achieve sufficient distal fixation by minimal splitting of the brachioradialis muscle to fix the most distal screws. The purpose of this retrospective study was to evaluate the efficacy of our modified anterolateral approach for Holstein-Lewis humeral fractures and document clinical and functional results.
Materials And Methods:
Between 2008 and 2014, 18 patients (mean age 35.4 years) with a Holstein-Lewis humeral shaft fracture who underwent open reduction and internal fixation with a plate and screws using the modified anterolateral approach and followed for a minimum of 12 months were included. Radiologic fracture configurations, number of distal cortical fixations, union rate, and time to union were analyzed. Clinical outcomes were evaluated using the Mayo elbow performance index system, range of elbow motion, and postoperative complications.
Results:
Mean fracture length was 60.2 ± 10.2 mm (range 49.2-77.2) and mean distal cortical length was 41.4 ± 7.04 mm (range 22.8-59.6). Distal fragments were fixed at a minimum of six cortical points (range 6-8) in all cases using the modified anterolateral approach. Average time to union was 10.5 weeks (range 8-12 weeks). All cases of radial nerve palsy completely recovered within 3 months. Mean elbow range of motion at final follow-up was 3.2 degrees of flexion contracture (range 0-10) and 135.4 degrees of further flexion (range 120-140), and the average Mayo elbow performance score was 96.3 points (range 90-100). There were no non-union or metal failures.
Conclusions:
The results obtained indicate that the modified anterolateral approach is a safe and easy accessible method that provides sufficient distal osseous fixation for Holstein-Lewis humeral shaft fractures without serious complications. The modified anterolateral approach for plate osteosynthesis appears to be one of the most available options for the treatment of Holstein-Lewis humeral fractures.
