[Clinical course of the quintus varus supraductus osteotomy in postoperative patients subjected to the LP-INR surgical approach].

OBJECTIVE To evaluate the clinical course of patients subjected to the osteotomy designed at the National Rehabilitation Institute (LP-INR) with a memory staple to treat the congenital quintus varus supraductus deformity, from December 2002 to August 2009. Moreover, to show that the LP-INR osteotomy decreases weight bearing under the 5th metatarsal head, descends the phalanx, spares the metatarsophalangeal joint, and prevents relapses and pain. MATERIAL AND METHODS The study was conducted from December 2002 to August 2009 and included 51 patients with quintus varus supra-ductus deformity and 78 feet; 33 patients were males (64.7%) and 18 were females (35.2%), the Maryland clinical scale was applied at postoperative month six. The AOFAS scale was applied in the preoperative and postoperative periods to assess pain, gait and alignment. RESULTS The Maryland scale showed excellent results in 42 patients (84.3%), good results in 3 patients (5.8%), fair in 3 patients (5.8%) with a score of 75 to 50, and poor in 3 patients (5.8%). The AOFAS scale score for the forefoot was 55 + 8 preoperatively and 90 + 5 postoperatively. The Student t test was statistically significant in the preoperative and postoperative periods < 0.05. DISCUSSION The LP-INR osteotomy for the treatment of the congenital quintus varus supraductus deformity provides appropriate alignment of the 5th toe with decreased load on the 5th metatarsal head and avoids broad resections that result in both cosmetic and functional alterations.
