Codman's self-published, subscription-only monograph — the first book in English written solely about the shoulder. Organized as a taxonomy of shoulder lesions (subacromial bursa pathology, rupture of the supraspinatus, calcified deposits, tendinitis of the short rotators) that Codman explicitly frames as a demonstration piece for the End Result Idea, not a shoulder text first: "this book is presented to you as a final illustration of my life work, rather than as a monograph on the shoulder."
Still directly influential: Charles Neer's own 1970 fracture-classification paper quotes Codman by name on the four-segment fracture concept. Codman's pendulum exercises remain a rehabilitation staple. His critical-zone reasoning anticipated Neer's "impingement syndrome" by ~40 years.
