Organized lance usage from a horseback may have become popular and widespread in 11th century (a.k.a. medieval heavy cavalry charge), but it has been used in ancient times as well as in Alexander the Great's conquests.
Spears were used in cavalry much before the Alexander’s hetairoi. The limitation in the frontal charges during the High Middle ages was a matter of horse breeds and the diffusion of chainmal and other types of armors. The descriptions of battles from the Dark Age in Northern Europe use to be the collision of two shieldwall, cavalry seems to play a secondary role and there is not any reference to frontal charges. The warhorses from the Sassanid cataphracts and the later European destriers were very corpulent and make it possible, but the original races from Northern Europe were almost poneys. Moreover, training a war horse for not be panic in the noisy confusion of battle was hard and expensive, not all the horses could be useful for a charge.
The textual evidences suggest for the Vikings, Celts and Anglo-Saxons was very difficult to raise an army with a significant number of horsemen with full armor. For a limited force of warriors over horses of around 145 cm tall, it has to be almost impossible to break a properly formed shieldwall.
