Abstract

OBJECTIVE:

To investigate the treatment method and effectiveness of fresh closed fracture-dislocation of the midtarsal joint.

METHODS:

Between April 2004 and April 2011, 73 patients (75 feet) with fresh closed fracture-dislocation of the midtarsal joint were treated with closed reduction combined with open reduction and internal fixation. There were 56 males (58 feet) and 17 females (17 feet), aged from 19 to 62 years (mean, 35.8 years). Injuries were caused by falling from height in 35 cases, by sprain in 4 cases, by machine twist in 5 cases, by heavy pound in 9 cases, and by traffic accident in 20 cases. The time from injury to admission ranged from 1 hour and 30 minutes to 48 hours (mean, 4.5 hours). According to Main's classification standard, 6 feet were rated as vertical compression injury, 33 feet as medial displacement injury, 17 feet as lateral displacement injury, 9 feet as flexion injury, and 10 feet as crush injury. Concomitant injuries included midfoot fracture-dislocation (34 feet), scaphoid fracture (6 feet), cuboid bone fracture (18 feet), calcaneal fracture (8 feet), talus fracture (7 feet), tibiotalar joint dislocation (2 feet), subtalar joint dislocation (2 feet), medial malleolus fracture (1 foot), and acute compartment syndrome (3 feet).

RESULTS:

Healing of incision by first intention was achieved in 65 cases (67 feet), by second intention in 8 cases (8 feet). Sixty-two cases (62 feet) were followed up from 11 months to 7 years and 11 months (mean, 3 years and 6 months). After operation, feet pain occurred in 26 cases, and stiffness or discomfort of the affected foot in 36 feet when walking. The X-ray examination showed good reduction of fracture-dislocation of the midtarsal joint and concomitant injuries with no re-dislocation or bone nonunion in 59 feet; 3 feet had flatfoot secondary to navicular necrosis, and underwent arthrodesis. The American Orthopaedic Foot and Ankle Society (AOFAS) score was 77-90 (mean, 88.6) at last follow-up.

CONCLUSION:

According to the preoperative evaluation of the damage, using the manual reduction combined with internal fixation (mini-plate or hollow screw with Kirschner wire) methods can obtain good effectiveness in the treatment of fracture-dislocation of the midtarsal joint.
