Background: Aim of this technical note is to describe the fabrication procedure of a new thermoplastic static-progressive hand-based splint for PIP joint flexion contractures, and report its effects in the treatment of a small group of sportsmen.
Methods: The serial-static splint consists of a short metacarpal gauntlet base, with a hole for the thumb and a dorsal finger gutter that extends to the distal extremity. A low-temperature thermoplastic material, two loop fastener straps, three small pieces of self-adhesive hook fastener and cooling spray are required. The orthosis has been tested on four professional volleyball players (3 females and 1 male), aged 18-24 years, suffering from PIP joint flexion contractures after traumatic hand injuries occurred 2 to 3 months before. Patients wore the splint for 1 hour followed by 1 hour of rest (6 times per day), for 2 to 3 weeks. During the resting periods patients performed a few sets of active ROM exercises at their PIP joint.
Results: This new splint design demonstrated to be effective in early recovery of complete PIP joint extension and subjects resumed soon their sports activity.
Conclusions: Our device is easy to fabricate and to use and comfortable for patients.
