A 31-year-old right-handed construction worker, referred from a minor injuries unit, presented with left ring finger pain from a spray gun injury with Newton 103-S(a type of liquid cement). Despite protective gloves, he had swelling, erythema, and necrotic skin. Tetanus immunization was administered, and urgent surgery revealed concrete
penetration causing tissue damage. pH was corrected, and subsequent debridements confirmed tendon continuity. Reconstruction was chosen over potential amputation.
A cross-finger flap was performed at one week, but wound infection at five weeks required additional interventions. At four months, the digit had limited range of motion and at 18 months, the patient reported no functional limitations, successfully returning to work with healed skin on both fingers.
