Abstract:
The proximal medial column of the humerus is a continuous cortical region in the inner and lower part of the humerus head, which has attracted more and more attention in clinical and scientific research since it was proposed. It has been shown to increase the stability of internal fixation, maintain the height of the humeral head to prevent varus, and reduce the risk of screw penetration. Biomechanical studies have also shown that the medial column has an outstanding performance in increasing the stiffness, torsion resistance, and shear resistance of the locking plate. Although it has many benefits, there is no unified definition of its concept and specific region, and the existing classification does not include the medial column, therefore more researches are required to provide supporting information. The methods of medial column reconstruction mainly include locking plate combined with talus screw, locking plate combined with bone grafting, internal and external double plate combined support, locking plate combined with bone cement, and humeral cage. These methods have their own characteristics, however they will increase the cost of surgery and bring new complications. How to determine the best way of reconstruction is one of the focuses of future research. In this review, the concept of the proximal medial humerus column, the role of maintaining internal fixation, the role of biomechanics and the reconstruction methods are reviewed.
