Hand Biomechanics Lab Digit Widget Patient Information

Controlling MP Hyperextension
Some patients with PIP flexion contractures may also hyperextend
at the knuckle (MP) joint. When the MP joint goes backwards
(Fig. 12), some of the extension force at the PIP joint is lost. To
control MP hyperextension, an MP Flexion Strap is included. Use
this strap only on the direction of your surgeon or hand therapist.
If directed to use the MP Flexion Strap, place the padded side
over the top of the involved finger as shown (Figs. 13 and 14).
Bend the MP joint as you securely attach the hook and loop
straps to the palm side of the Cuff placing the pad over the top of
the finger. The straps and pad may be trimmed as needed.

Maintenance
1. Replace the Elastic Band(s) daily. Always follow your
surgeon or therapist's instructions regarding the number and
color of bands to use and the time worn each day. You may
find that using the included Band Applicator Tool makes it
easier to change the bands.
2. Follow the advice of your surgeon to care for the pin sites.
3. Your surgeon can order replacement Cuffs from Hand
Biomechanics Lab.
4. The sliding action of the Connector Assembly may become
compromised due to exposure to foreign substances during
the course of daily activity. If you experience problems,
you may need to disconnect the Connector Assembly as
described in the "Removal for Hand Washing" instructions
and wash it in warm soapy water. Rinse thoroughly, air dry,
and reassemble the device. After washing, the Connector
Assembly should slide freely on the rod. Do NOT apply oil
to the rod inside the Connector Assembly.
5. If you develop a rash or skin irritation under the Cuff, a
cotton stockinet may be worn under the Cuff.
6. Do not hesitate to call us if you need more Elastic Bands.
