What is Rower's wrist / intersection syndrome?
Tendons that straighten the thumb and those that straighten the wrist cross paths on the back of the wrist. Irritation at this intersection due to overuse (e.g. rowing, repetitive strong gripping) can case “Rower’s wrist” or “intersection syndrome”.
Symptoms include pain and swelling over the back of the wrist, sometimes a gritty sensation can be felt when moving these tendons.
Treatment for intersection syndrome
Treatment of Rower’s wrist / intersection syndrome is nearly always non-surgical.
Rest and splinting is usually a very successful treatment. If that fails, a steroid injection can provide relief. If complaints persist, surgical release of the tunnel of the wrist tendons can be considered.
