PATIENT PRESENTATION

The patient is a 48-year-old woman who started a new job 6 months ago as a bookkeeper. She has been experiencing pain in the right wrist for approximately 1 month. The pain and tenderness are in the region of the styloid process of the radius. She states that the pain radiates into the forearm and thumb as her day progresses. She states that the pain began as a dull ache at the end of the day, but has progressed to the point of inability to complete her morning activities because of the discomfort. Her daily routine includes counting bills and receipts in the morning using her right hand with a repetitive pronation to supination movement. In the afternoon, her work is primarily done utilizing a keyboard. She has no hobbies, but does routine housework and cooking for herself and her spouse.

Finkelstein test. The patient places the thumb in the palm and makes a loose fist. The examiner then ulnarly deviates the patient’s wrist (as indicated by the arrow). Pain at the first dorsal compartment with this maneuver is a positive response. (From Brunicardi FC, Andersen D, Billiar T, et al., eds.

Essentials of Diagnosis
++

  • Tenderness with palpation

  • Positive resisted isometric test in thumb abduction and extension

  • Finkelstein test is best for diagnosis3

++
General Considerations
++

  • Entrapment tendonitis, tendon friction

  • Often a direct result of repetitive stress or chronic overuse of extensor and abductor muscles causing excessive friction to tendon sheath

  • Patients likely to develop adhesions and irritation between tendons and their sheaths

++
Demographics
++

  • Mostly found in women aged 30 to 50 years, possibly due to great angle of the styloid process

  • Common among individuals who perform any activity requiring repetitive hand and wrist movement

  • At-risk populations include

    • Massage therapists

    • Musicians

    • Milliners

    • Gardeners

    • Office workers

    • Pregnant and postpartum women
