Dorsiflexory Phalangeal Osteotomy for Grade II Hallux Rigidus: Patient-Focused Outcomes at Eleven-Year Follow-Up.Dorsiflexory phalangeal osteotomy has been shown to be an effective treatment for mild to moderate hallux rigidus in short- to medium-term follow-up studies. It is speculated that the procedure alters the mechanical function of the joint and reduces the demand for hallux dorsiflexion by elevating the proximal phalanx into a more dorsiflexed position. However, it has been demonstrated that the first metatarsophalangeal (MTP) joint space and joint range of motion are reduced by the procedure, calling into question the long-term effectiveness of the operation. This study reviewed 27 dorsiflexory phalangeal osteotomy cases at an average of 11 years postoperatively. Twenty-one (77%) patients reported that they were completely satisfied with the results of their surgery; 4 (15%) patients reported that they were satisfied with reservations; and 2 (7%) patients reported that they were dissatisfied. The patients who were satisfied with reservations complained of interphalangeal (IP) joint pain or stiffness. One patient developed second MTP joint metatarsalgia after surgery, and in 1 patient first MTP joint pain returned at 24 months after surgery. One dissatisfied patient complained of second MTP joint metatarsalgia, and a second patient required revision excisional arthroplasty for continued joint pain. Ten patients (38%) reported stiffness of the first MTP joint, but only 2 patients reported any restriction of activity. Footwear restrictions were reported by 15 (58%) patients preoperatively and by 9 (35%) patients at final follow-up. Dorsiflexory phalangeal osteotomy maybe a reliable long-term treatment for grade II or moderate hallux rigidus and is a safe and effective alternative to first MTP joint fusion in joints where movement is still present and joint cartilage is viable.
