Blount and Clarke's 1949 case series describes the technique of epiphyseal stapling at the distal femur and proximal tibia to reversibly arrest physeal growth in children. The central question: can mechanical compression across a physis reliably stop elongation, and will growth resume after hardware removal? This is the paper that transformed growth modulation from permanent epiphysiodesis into a titratable, reversible procedure.
Epiphysiodesis before 1949 was a one-way door: Phemister's technique permanently destroyed the physis, requiring accurate growth prediction years in advance — a task Blount himself called "inadequate in the face of individual variations."
Blount's stapling showed that the physis could be paused and restarted. When you see a child with progressive angular deformity or limb length discrepancy, this paper is why you think in terms of guided growth rather than permanent arrest: staple early, watch clinically, remove when alignment is achieved.
The practical rules that come directly from this paper: use three staples per side (not one or two), do not leave staples in for more than two years, and time removal by watching the patient walk rather than relying solely on radiographic measurement.
Blount's core insight. Asymmetric physeal compression corrects angular deformity. Remains the mechanistic backbone of the modern 8-Plate tension band system (Stevens, 2007), which replaced staples with a more forgiving implant while preserving the identical biological logic.
