Metacarpal Fractures: Achieving Best Outcomes

---

1.  This anatomical structure at the MCP joint is the reason the MCP is flexed to 50-70 degrees of flexion in the "safe position": Collateral Ligament Sagittal Bands Volar Plate Lumbricals

2.  When fabricating an orthosis for a reliable patient with a 5th MC base fracture, the _________ joint may be left free given the risk is minimal that motion here will cause issues with healing. Wrist IP CMC MCP

3.  This is the type of fracture healing that occurs with fixation that allows a slight amount of movement during healing which spurs on the formation of a callous. Secondary Healing Primary Healing Intrinsic Healing Extrinsic Healing

4.  With a patient that has been treated conservatively for an oblique metacarpal fracture with interval callous formation, what type of exercise would you initially begin with? Intrinsic stretching Squeezing a stress ball Active tendon glides Isotonic wrist curls with three pounds

5.  If PIP flexion is greater with MCP flexion than with MCP extension, what type of tightness would you provide stretches for? Long Flexor Tightness Intrinsic tightness Long Extensor tightness PIP join tightness

6.  What adjustments would you make to an ulnar gutter orthosis if the patient had surgical fixation with external k-wires? Make sure you achieve 30 degrees of PIP flexion Create a bubble around their MCP joint Create a bubble around their pins Make sure you leave the pins exposed

7.  What scenario would justify initiation of grip strengthening as part of your treatment regimen? MC FX treated conservatively at post injury week eight with dense callous formation MC FX with plate and screw fixation at post op week one MC FX treated with K-wire fixation immediately after pin removal at post op week four MC FX treated with IM rod at post op week one

8.  What type of orthosis would be helpful in later stages of healing when there are significant limitations in active and passive MCP flexion of the small finger? Anti Claw Orthosis Static Progressive MCP flexion orthosis Webspacer Orthosis Ulnar Gutter Orthosis Forearm Based

9.  Compression of which nerve can cause issues with full active composite fist and it would be the reason a therapist chooses to use a wrist orthosis at night later in the rehabilitation process? Ulnar Nerve Musculocutaneous Nerve Median Nerve Radial Nerve

10.  In the case of a Bennett's fracture with rigid fixation, AROM can start as early as: 4 weeks post operatively Post op day one 5 weeks post operatively 2 weeks post operatively
