[Diagnosis and surgical treatment of tarsometatarsal joint complex injuries]

To explore the diagnosis and surgical treatment of tarsometatarsal joint complex injuries.

Between January 2000 and October 2009, 24 cases of tarsometatarsal joint complex injuries were treated. There were 14 males and 10 females with an average age of 38 years (range, 21-65 years). Injury was caused by a machine in 8 cases, by traffic accident in 12 cases, and by falling from height in 4 cases. All fractures were closed. The time from injury to hospitalization was 2-17 hours (5 hours on average). Open reduction and internal fixation with screw were performed.

Incision healed by first intention in other patients except 1 patient who had effusion at incision. Twenty-three cases were followed up 12-47 months with an average of 23 months. X-ray films showed that all fractures healed after 9-15 weeks of operation (13 weeks on average). No complication was found, such as osteofascial compartment syndrome, nonunion infection, loosening or breakage of the internal fixator. According to Maryland scoring, the results were excellent in 7 cases, good in 8 cases, fair in 5 cases, and poor in 3 cases with an excellent and good rate of 65.2%.

Anatomical reduction and stable fixation are important for satisfying results in treating tarsometatarsal joint complex injuries.
