Kirschner wire breakage after surgery of the lesser toes.
A retrospective review was made of all patients operated on by the two senior authors from January 1985 to January 1993 for problems with Kirschner wire breakage following forefoot surgery. Thirty-three broken K-wires in 27 patients were encountered. All of these were 0.045-inch K-wires that had been placed across the metatarsophalangeal (MTP) joint of the lesser toes. In no case was there breakage of a K-wire that was larger than 0.045 inches or that did not cross the MTP joint. The medical records and radiographs of 565 consecutive patients having fixation with 0.045-inch K-wires that crossed the MTP joints of the lesser toes were then reviewed. A total of 1002 K-wires were used with an overall failure rate of 3.2% (4.8% of the patients). All of these K-wires failed just proximal to the point of entry into the metatarsal head. No intra-articular retained fragments were noted. Twenty-five of the retained fragments were completely within the metatarsal head and shaft, and eight of these fragments pierced the cortex of the metatarsal proximally. Twenty-three patients with retained fragments were examined in follow-up and in no case could the retained fragment be palpated or directly related to postoperative symptoms. Of the three patients who complained of persistent pain, two had mild pain with persistent MTP synovitis and one had severe pain due to lateral deviation of the toe after surgery.(ABSTRACT TRUNCATED AT 250 WORDS)
