Residual Extensor Lag Approximately 1 Month After Splint or Cast Immobilization of a Mallet Finger

Aim:

The purpose of the study is to learn more about how a person recovers after treatment for
mallet finger injury. The investigators want to identify the best outcome after mallet
finger injury and how to improve treatment strategies.

Primary null hypothesis:

There are no statistically significant factors associated with extensor lag between 4 weeks
and 4 months after immobilization is discontinued for a mallet finger among demographic,
injury, and treatment factors.

Secondary null hypothesis:

There are no statistically significant factors associated with PROMIS upper extremity
function between 4 weeks and 4 months after completion of immobilization for a mallet finger
among demographic, psychological, injury, and treatment factors.
