Skier's Thumb (cont.)
Skier's Thumb Diagnosis
The physician will first determine whether or not the patient has other
limb-threatening injuries and then evaluate
the thumb in more detail.
The doctor will ask the patient how the injury happened. The patient will be
asked the following questions:
- At what time did the injury take place?
- What was the exact positioning of the hand and thumb during the injury?
- How soon after the injury did the pain and swelling begin?
- Did it feel as if the thumb was stressed beyond its normal range of motion?
The doctor will also ask about the patient's past medical history. The
patient will be asked the following questions.
- Have you ever suffered from a similar injury before?
- Have you ever had any type of surgery in your hand or wrist?
- Are you allergic to any pain medications?
- Have you ever fractured any bones in your wrist or
- Are you right-handed or left-handed?
- What is your primary occupation?
The doctor will then perform a physical examination.
- Testing the laxity (looseness) of the ulnar collateral ligament of the thumb: This test will be done by holding the base of
the thumb in a fixed position, while applying a lateral (sideways) force on the tip of
the thumb to see how many degrees it will move. This movement will be compared to the movement of
the other, uninjured thumb. Pain may make this difficult to do immediately after the injury (in which case the injury may be treated and then reexamined in a few days).
- Assessing for normal functioning of the three major nerves in the hand
- Checking for point tenderness over certain bony spots of the hand that may indicate fracture
- X-ray of
the hand to make sure no bones are broken
- Examining the rest of the arm for any associated injuries to your wrist, forearm, elbow, and shoulder
