Other Names

  • Bunnell's intrinsic tightness test
  • Bunnell Littler Test
  • Finochietto-Bunnell Test

Purpose

The Bunnel Litter Test[1]
  • Helps identify the source of PIP tension or flexion motion limitation by evaluating the intrinsic muscle or capsular tightness in the affected digit.
  • May also be used to determine osteoarthritis.

Description

  • Locate and extend the MCP joint and flex the PIP joint. Take note of the range of motion of the affected digit.
  • Repeat the procedure but this time the MCP joint should be flexed.
  • Positive Test
    • Decreased motion, suggesting capsule contraction or osteoarthritis
    • No change in motion, sugests capsular restriction at PIP joint
    • Increased motion, lumbrical muscle tightness may be present

Pathology

  • Osteoarthritis of the finger
  • Capsule contraction of PIP joint
  • Lumbrical muscle tightness

Evidence

  • None
