Instability of the joints at the base of the finger (the knuckle joints) may allow the fingers to stray to the side or cross over or under each other, making it difficult to hold objects or work on a computer. If a finger cannot actively be brought into alignment with the adjacent finger, it may catch on things causing great pain. Splinting to hold two fingers together, or “buddying”, creates better alignment and improves function.
For Adduction or Abduction of the Fingers
Use the SIRIS™ Buddy Ring to “buddy up” a straying finger with a neighboring finger. It is appropriate when there is stability in an adjoining finger, but not for ulnar drift of all digits due to rheumatoid arthritis.
Buddy Ring Offsets
You can order the SIRIS™ Buddy Ring with no offset, half offset or full offset between the rings. “No offset” positions the rings side by side, creating slight abduction of the fingers. “Full offset” positions one ring distal to the other ring to follow the webspace of the hand or to place one ring farther from the web space to assist with finger adduction.
2 ½ Buddy Ring
Use the SIRIS™ 2 ½ Buddy Ring, which has two rings connected by a one-half ring, to align fingers that are abducting, crossing or have an extension lag. This type of deviation may arise following trauma, post polio or from tendon transfers.
Use the SIRIS™ Pulley Ring to manage bowstringing at the A-2 pulley. To determine the width of the ring, measure proximal to the PIP volar crease to allow full flexion. If a Pulley Rings will not fit tight enough due to a large PIP joint, feel free to contact us about the Hinged Pulley Ring we have been developing.
