Orthoses for Painful Fingers

October 31, 2019

Orthotic fabrication for the treatment of finger osteoarthritis

Osteoarthritis (OA) is a chronic disease which can result in painful joints and limited functional ability. OA of the hand is the most common and affects women three times more than men.

Most articles and studies have looked at interventions for OA of the thumb CMC joint. But painful fingers can also cause a variety of functional deficits, which include:

  • Decreased grip and pinch strength
  • Decreased range of motion
  • Decreased performance during everyday activities

Luckily, there are various therapeutic interventions, including orthotic fabrication, that can ease painful fingers and help patients to carry on with their day-to-day activities.

Orthotic Fabrication for Fingers: Current Research

A recently published systematic review (Beasley et al, 2019) in the Journal of Hand Therapy evaluated the evidence for therapeutic interventions specifically for finger joints with osteoarthritis. This is the first systematic review to target interventions for the proximal inter-phalangeal (PIP), distal inter-phalangeal (DIP), and thumb inter-phalangeal (IP) joints.

The review focused on finger joint interventions that included:

  • AROM exercises
  • Thermal modalities
  • Laser therapy
  • Joint protection techniques
  • Yoga
  • Orthotic fabrication

Decreasing pain is the main focus of these therapeutic interventions.

Only two of the eighteen studies reported on the use of orthoses to manage symptoms of finger joints with OA. Ikeda et al (2010) and Watt et al (2014) both evaluated the use of orthoses for the distal interphalangeal joint. These two studies demonstrated that wearing a customized DIP orthosis significantly reduces pain in finger joints with OA.

Clinicians can reference the information provided by systematic reviews such as this one and also use good clinical judgment to choose appropriate patient-centred treatment options.

Material Choices for Finger Orthoses

Choose lightweight thermoplastic materials to fabricate comfortable orthoses for painful fingers. The following can all be used to make excellent finger orthoses:

  • Orfilight (NS) in 2.5 mm (1/12”) and 1.6 mm (1/16”)
  • Orficast and Orficast More
  • Orfit Classic
  • Aquafit NS (Orfit Natural NS)
  • Orfit Colors NS
