Plastic Finger Splints

Selecting the proper size is critical for effective immobilization. As indicated in the specifications, sizing is determined by both the length and the diameter (circumference) of the affected finger. You should measure the distance from the fingertip to the first joint (the distal interphalangeal joint) and the width of the finger pad. The splint should fit snugly enough to hold the fingertip in slight hyperextension or neutral extension without being so tight that it compromises circulation. Given that the splints are sold in a 12-pack with assorted sizes ranging from #1 to #7, this allows clinicians to fit a wide variety of patient anatomies accurately.

The primary difference between the two options is aesthetic, though they share the same functional integrity. The clear tone splints offer a discreet, medical-grade transparency that is often preferred for its low visibility against various skin tones or for allowing clinicians to easily monitor the underlying skin condition. The skin tone splints are designed to blend with natural flesh tones, offering a cosmetic advantage for patients who prefer the splint to be less conspicuous during daily activities. Both colors are manufactured from the same lightweight, durable plastic and are available in the full range of sizes to ensure clinical efficacy does not compromise patient preference.

Consistent wear is essential for the successful repair of ruptured tendons, such as in mallet finger injuries. The splint must be worn continuously—typically for 6 to 8 weeks—to maintain the fingertip in extension, allowing the tendon to reattach to the bone without interruption. Removing the splint prematurely, even briefly for cleaning, can disrupt the healing process and lead to recurrence of the deformity. We recommend securing the splint with medical-grade tape and advising patients to keep the splint dry and intact throughout the immobilization period, only removing it under the direct guidance of a healthcare professional for skin inspection.
