Abstract

Background: Adult humeral shaft fractures have traditionally been managed conservatively, but surgical intervention is considered for displaced fractures or when conservative treatment is unlikely to be successful. The optimal surgical approach remains controversial, with open reduction and internal fixation (ORIF) using plates and screws considered the gold standard. However, concerns about soft tissue damage have led to the development of less invasive techniques, such as anterior bridge plating using minimally invasive plate osteosynthesis (MIPO). This study aimed to evaluate the outcomes of MIPO for humeral shaft fractures.

Methods: A prospective cohort study included 43 patients who underwent anterior bridge plating with MIPO for closed, displaced humeral shaft fractures. Forty patients had full follow-up (functional and radiological) and three patients were lost to follow-up. Fractures were classified using the AO classification system. Surgical technique involved incision, reduction, and fixation with locking compression plates. Follow-up assessments were conducted at various intervals, and functional outcomes were evaluated.

Results: Fracture union was achieved in 38 of 40 patients (95%). Two patients required secondary bone grafts for non-union. The mean time to union was between 12 and 16 weeks. Excellent shoulder function was observed in 82.5% of patients, and excellent elbow function in 77.5%. The range of motion on the operated side differed statistically significantly from the nonoperated side but was not clinically significant.

Conclusions: MIPO with anterior bridge plating is a viable option for the surgical management of humeral shaft fractures. It offers good fracture healing rates and satisfactory functional outcomes and avoids extensive soft tissue dissection associated with ORIF. Level of evidence: II.
