A 64-Year-Old Man Consulted His Physician Because He Had Noticed

A 64-year-old man consulted his physician because he had noticed during the past 6 months a thickening of the skin at the base of his left ring finger. As he described it: "There appears to be a band of tissue that is pulling my ring finger into the palm." On examination of the palms of both hands, a localized thickening of subcutaneous tissue could be felt at the base of the left ring and little fingers. The metacarpophalangeal joint of the ring finger could not be fully extended, either actively or passively.
-The following statements concerning this patient are correct except which?

A) The deep fascia beneath the skin of the palm is thickened to form the palmar aponeurosis.
B) The distal end of the aponeurosis gives rise to five slips to the five fingers.
C) Each slip is attached to the base of the proximal phalanx and to the fibrous flexor sheath of each finger.
D) Fibrous contraction of the slip to the ring finger resulted in permanent flexion of the metacarpophalangeal joint.
E) The patient had Dupuytren's contracture.
