From January 2010 to January 2017, 81 complete flexor digitorum profundus tendon disruptions in Zones 2B and 2C were treated using the modified Mantero technique. The patients were re-examined at a mean of 62 months (range 30-96) after operation. We analysed outcomes against ages, gender, pulley integrity, associated injuries and follow-up times. The median total range of motion of both interphalangeal joints, distal interphalangeal joint alone and Quick DASH scores were significantly better for the group with pulley vented versus no pulley vented. According to the Strickland and Glogovac criteria, 76 (91%) had excellent or good, five fair and none had poor results. There were no complications except for one deep and one superficial infection at the site of the injury. There were no tendon ruptures and only three patients (3.7%) required secondary tenolysis. The modified Mantero repair is recommended as an alternative in the repair of tendon disruptions in Zone 2B and 2C. The good results and absence of ruptures suggest that the tendon healing and strength of repair are adequate for immediate postoperative motion.Level of evidence: IV.
