In what position is the tibial sesamoid considered abnormal?

The tibial sesamoid being positioned above 3 is considered abnormal due to its implications for the biomechanics of the foot and potential for conditions such as sesamoiditis or metatarsalgia. In an optimal position, the sesamoids typically lie within a certain range that allows for proper function during activities such as walking and running. When the tibial sesamoid is positioned above the designated limit, it can disrupt the normal weight-bearing function and may lead to increased stress on the first metatarsal and adjacent structures.

A thorough assessment often includes evaluating the alignment and position of the sesamoids with respect to the metatarsal heads. In clinical practice, abnormal positioning can indicate underlying structural issues or potential for injury. Understanding the typical anatomic relationships and their variations is crucial for diagnosis and treatment planning in podiatric medicine.
