Kienbock Disease in Adults 21–69 with Intact Lunate: Next Step When Wrist Immobilization Has Not Worked

For adults aged 21–69 with Kienböck disease and a confirmed intact lunate, a structured escalation pathway applies when conservative management has not achieved the required clinical goals.

Clinical scenario: Patient aged 21–69 with Kienböck disease. The lunate remains intact — not fractured, with functional articular surfaces — confirmed by imaging consistent with Lichtman stage 0, I, or II, Schmitt MRI stage A, and Bain arthroscopic grade 0.

Previous treatment — basis for escalation

Nonoperative management — wrist immobilization with a short arm cast or splint for at least 3 months, combined with avoidance of strenuous activities — was the prior step. This protocol applies when wrist pain has not resolved or when imaging shows disease progression (lunate collapse) at the 3-month reassessment.

Next intervention — partial overview

When conservative management fails, a lunate unloading or revascularization procedure is considered. Several surgical options exist; which approach is selected depends on specific anatomical and radiographic factors. The complete selection algorithm and full protocol are available in the structured regimen.

For patients 21 to 69 years, proceed to sections B or C, as appropriate.

The lunate is "intact" if it is not fractured and the articular surfaces are "functional."

Lichtman stages 0, I, and II, Schmitt stage A, and Bain grade 0 all represent an intact lunate.

If the patient is symptomatic after 3 months, or imaging demonstrates disease progression, a lunate unloading or revascularization procedure is considered.

Lunate unloading is often used for patients with intact lunates who fail nonoperative treatment.
