[Coraco-trochineal conflict or anteromedial conflict of the shoulder. Contribution of arthroscanners].
Like the anterosuperior subracromial conflict, the coracotrochineal or anteromedial conflict of the shoulder is a groove pathology. In a series of 340 patients who had an arthroscan of the shoulder, including 245 with a conflict syndrome (70%), we observed an anteromedial conflict in 12 cases (8.5%) of the 140 patients with an intact cuff and 52 cases (50%) in 102 patients with an injured cuff. The frequency of the anteromedial conflict appears to be proportional to the degree of cuff injury. We described the signs of the trochin suggesting the anterior musculotendinous structures (subscapsular tendon and/or long biceps tendon) are involved and conclude that the anteromedial conflict is often misdiagnosed. It would appear to be a frequent complication of cuff injury (mechanical theory) which the surgeon should take into consideration when repairing cuff injury.
