There are no actual figures readily available for this however, nearly every forward in both codes has suffered an injury at some point when scrummaging. This can be anything from bruising to sadly near fatal injuries. The front row are particularly susceptible to injury which is why their positions cannot have any other position taking the role on they must be from row specialist or the scum becomes uncontested
In Rugby the scrum is made up of eight forwrds from each team so a total of 16 players are involved in a full scrum.

a scuffle in rugby scrum
technically I believe No you cannot add players to the 3 rows that are defined as the scrum added to this is the fact that a contested scrum cannot take place unless the front row contains the trained props and hooker.
Most rugby players wear shoulder pads, which protects them when they tackle and for when they are in a scrum or ruck. The players who go in the scrums and rucks wear scrum hats, this prevents them from head injuries, but also prevents cauliflower ears. And nearly all the players wear gum shields to protect their teeth.
Its common name is a RUCK.

Players piling on each other to move the ball and or gain position for themselves forms a scrum in the game of Rugby.
