A 37-year-old man who works in construction presents to the emergency department after sustaining a fall from a roof. He attempted to stop his fall and grabbed onto a piece of sheet metal which subsequently lacerated his middle finger. A clinical photo is presented in Figure A. He has 4 mm two-point discrimination to both the radial and ulnar aspects of the digit and can flex both the distal and proximal interphalangeal joints upon command. His laceration is irrigated and probed. The flexor digitorum profundus and superficialis tendons are both uninjured. The wound is closed primarily, and he is referred to a hand surgeon. Which of the following sequela are most likely to occur if the patient does not undergo surgical treatment of the injured structure indicated in Figure A?
