JBJS Classics: Pollicization of the Index Finger

JBJS Classics Logo.pngOrthoBuzz regularly brings you a current commentary on a “classic” article from The Journal of Bone & Joint Surgery. These articles have been selected by the Editor-in-Chief and Deputy Editors of The Journal because of their long-standing significance to the orthopaedic community and the many citations they receive in the literature. Our OrthoBuzz commentators highlight the impact that these JBJS articles have had on the practice of orthopaedics.

Even before hand surgery became a specialty, the characteristics of the thumb that enabled pad-to-pad opposition (and therefore fine motor function) were well-recognized:  shorter length, fewer bony segments, and pronated position relative to the fingers; a wide first web space; and intrinsic muscle control of abduction, rotation, and pinch.  Although these principles were used to devise surgical procedures to restore thumb function prior to Buck-Gramcko’s landmark JBJS article in 1971, most were used for a small number of patients, with limited information available about outcomes.  Thumb absence is uncommon, and no hand surgeon was able to gain sufficient experience with index pollicization to refine and enhance the technique until the confluence of Buck-Gramcko’s exceptional skill and one of the major medical catastrophes of the 20th century.

Dieter Buck-Gramcko was born in Hamburg, Germany in 1927.  Following World War II, he trained in general and trauma surgery and became one of the first hand surgeons in Germany.1  Between 1957 and 1962, thalidomide was marketed in Germany as a sedative, but it also inhibited angiogenesis, causing limb malformations, including thumb deficiency, when fetuses were exposed to the drug during limb development.2  The resulting large number of German infants with thumb deficiency provided Buck-Gramcko with the opportunity to modify the technique of index pollicization and study the outcomes of his modifications to improve results. He described his findings and results in this landmark article.

His careful description of index pollicization includes the principles and techniques that remain the hallmarks of this operation.  His diagram of reduction of bones and joints (Figure 3 of his classic article, shown below) is a simple and elegant depiction of the principles of this complex operation.  His rigorous follow-up, measurement of outcomes, and propensity to criticize his own work to improve results are all apparent in this article, which provides an excellent example of applying the scientific method. Not surprisingly, Buck-Gramcko remained rigorous and objective throughout his long career; 20 years later, he published another article focused on complications and poor outcomes after index-finger pollicization.3James Classic Image.png

Index pollicization is one of the paramount operations of hand surgery, largely because Buck-Gramcko applied theoretical principles of thumb function, methodically and meticulously refined the technique of pollicization, studied the outcomes of his work, and passed this valuable information along in this classic article.  It remains a useful guide to the performance of this operation almost half a century later.  The thalidomide tragedy had a silver lining, thanks to Buck-Gramcko’s surgical skills, methodologic rigor, and scientific objectivity.

JBJS/JOSPT Webinar: Basilar Thumb Arthritis—October 13, 1:30 PM EDT


Thumbs account for approximately 40% of human hand function, playing a critical role during work, play, and activities of daily living.  Arthritis at the base of the thumb (basilar or trapeziometacarpal joint) is one of the most common forms of hand osteoarthritis, affecting as many as 40 percent of the female population older than 55.

This complimentary webinar, hosted jointly by The Journal of Bone & Joint Surgery (JBJS) and the Journal of Orthopaedic & Sports Physical Therapy (JOSPT), will look at the efficacy of both nonoperative and surgical approaches to basilar thumb arthritis.

  • Co-authors Jorge Villafañe, PT, PhD, and Joshua Cleland, PT, PhD, will discuss results from a randomized trial in JOSPTthat compared a multimodal program of exercise and mobilization to a placebo in the management of basilar thumb arthritis.
  • E.R. Hovius, MD, co-author of a randomized trial in JBJS comparing trapeziometacarpal fusion with trapeziectomy plus ligament reconstruction, will delineate the findings from this Level I study.

Moderated by Sanjeev Kakar, MD, a hand surgeon at the Mayo Clinic in Rochester, Minnesota, the webinar will include additional perspectives from two expert commentators—Krysia Dziedzic, PhD, and Peter Stern, MD.

JBJS JOPA Image Quiz: A Teenager with Thumb Pain After Hand-First Slide

JOPA IQ ThumbThis month’s Image Quiz from the JBJS Journal of Orthopaedics for Physician Assistants (JOPA) describes the case of a 14-year-old boy with a history of a bifid first metacarpal who injured his thumb while sliding hand-first into a base during a baseball game. Anteroposterior and lateral radiographs of the thumb are shown, and findings from the physical exam are detailed in words and photos.

The Image Quiz reviews the function of and injuries to the ulnar collateral ligament (UCL), including the injury classically described as “skier’s thumb.” Pick the best among four possible next steps in diagnosing and treating this injury.
