DefinitionThe lumbricals are small muscles of the hand that are not attached to the bones but to tendons. They are located between the tendons of the flexors and the extensor tendons of the finger at the palm of the hand (fig 1).

Mechanism of the lesionA one finger hold grabbed with a stretched finger while the others are bending, stretch the correspondent lumbrical muscle irreparably.

one finger hold
It is imperative to modify the grabbing technique of one finger holds by never separating the middle and the ring finger (fig 4).
Fig 4: Risk free grabbing of a one finger holdCorrection of the physical preparation:
Stop the session and put some ice on it immediately. You also might want to try a compression (not really easy in that area).
Repeat ice treatment 3 to 4 times per day for 3 to 7 days. Do not apply anti-inflammatory gel.
A specific physical therapy combining ultrasound therapy, mobilization and stretching can help to optimize recovery.
Stop training for 10 to 30 days (depending on the importance of the lesion, determined by a sonogram). When you start training again do so progressively by strapping the middle finger together with the ring finger and without using one finger holds.
