Treatment of tarsometatarsal joint injury combined with metatarsal fracture by open reduction and internal fixation / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the therapy and the key points of the tarsometatarsal joint injury combined with metatarsal fracture.</p><p><b>METHODS</b>From Jan. 2006 to Jul. 2008,19 patients with tarsometatarsal joint injury combined with metatarsal fracture were treated with opened reduction and internal fixation of Kirschner wire or screws, included 13 males and 6 females with an average age of 38.1 years ranging from 21 to 56 years. The classification of tarsometatarsal joint injury showed that there were 2 cases of inner column injury, 5 cases of inner and medial column injury, 3 cases of lateral and medial column injury, 9 cases of tri-column injury. There were 8 cases of shaft fracture, 7 of neck fracture, 19 of foundation fracture.</p><p><b>RESULTS</b>All the incisions were first stage healed without skin necrosis. The healing time of fracture was 11.2 weeks on average. All the patients were followed-up for 6 to 17 months with an average of 12.8 months. According to the standard of AOFAS, the average score was (84.500 +/- 8.553), the results were excellent in 4 cases, good in 9 cases, fair in 3, and poor in 3. The regular daily life was recovered after 6.4 months, 3 patients suffer from mild osteoarthritis.</p><p><b>CONCLUSION</b>No matter which fixed mode was used, the anatomical reduction was the most important to rebuild arches of the foot and recover medial longitudinal and lateral arch. Rebuilding arches of the foot guaranteed the integrity of the stress point scaffold and avoided the pain and limp. The anatomical reduction of tarsometatarsal joint and metatarsal was also important to rebuild the function of foot.</p>
