Unipolar Versus Bipolar Interlocking in Humeral Shaft Fractures in Adults

Shaft fractures account for 20% of humeral fractures and 3% of all adult fractures in France, with an estimated incidence of 13 to 20/100,000 people. Men aged 21 to 30 years and women aged 60 to 80 years are particularly affected. Intramedullary nailing is among the standard treatments for humeral shaft fractures (when surgery is required). Once inserted, the nail is locked in order to limit stress on the fractured bone, as well as possible secondary rotational displacements or malunion. Bipolar interlocking (BI) is typically performed on both sides (proximal and distal) of the fracture site. This procedure is performed under radiological control, exposing the patient and care team to radiation (during the entire procedure). The objective of the treatment is to obtain consolidation of the fracture within 12 months, and to limit the occurrence of irreversible complications such as malunion or nonunion (2-10% at 12 months post-surgery). The "unipolar interlocking" (UI) technique has recently been introduced. In this technique, locking is performed only on the proximal side of the fracture site. By avoiding the distal approach, potential complications such as radial nerve damage, with the risk of irreversible paralysis (3.8-14.2% in studies of the BI technique in this indication) or the risk of infection on the distal side can be avoided. It also reduces operative time, and consequently the radiation received by patients and caregivers. However, the UI may be poorly positioned, …
