Introduction: The aim of this study is to retrospectively assess functional and radiological outcomes, and immediate and long-term post-surgical complications in a series of patients with humeral fractures treated with osteosynthesis using a minimally invasive technique. Methods: Retrospective multicenter study of 14 patients with humeral fractures treated with minimally invasive plate osteosynthesis through lateral approaches between 2007 and 2013. Seven were females and 7 males, age averaged 48.7 years (range 21-73). Fractures were classified according to the AO classification: 12A1 (n = 1), 12B1 (n = 1), 12B2 (n = 3), 12C1 (n = 6), 12C2 (n = 1), and 12C3 (n = 2). Two lateral incisions (proximal and distal) were used. The plates were slid through a submuscular canal, and the radial nerve was protected. Results: Follow-up averaged 30 months. Union was achieved in 13 cases (92.85%), time to union averaged three months (range, 2 to 6). Flexion averaged 174.8°, external rotation was 67.2°, abduction 173.8º and internal rotation 72.1°. Elbow flexion and extension averaged 140.5°. Constant score averaged 82.66 points; DASH score averaged 15.27 points. Four patients had radial nerve neurapraxia (23.5%). Conclusions: Percutaneous osteosynthesis with plates using a lateral minimally invasive approach has proven effective for the treatment of humeral shaft fractures, applying the principle of bridge plate. It is a biological, technically demanding procedure but not free from complications.
