Category: Trauma Introduction/Purpose: The first tarsometatarsal (TMT) joint is very crucial for midfoot stability. To address its importance, retrospective analyses of treatment for the first TMT joint dislocation with Lisfranc injury was performed in a multi-center manner. Comparison of open reduction internal fixation (ORIF) and primary arthrodesis was conducted for the injury. Methods: This multi-center study was involved ten clinical institutions in different area of China. .From January 2003 to June 2015, 126 Lisfranc injuries with first TMT joint dislocation underwent surgical intervention. Of this group, forty one (32.5%) feet were first TMT joint dislocation only. Eighty five feet were first TMT joint dislocation and fractures. They were 76 males (60.3%) and 50 females (39.7%) with a mean age of 45.5 (range, 20-87) years. The duration from injury to surgery is 11.7 (range, 4-26) days. Two groups were divided by surgery methods as open reduction internal fixation (ORIF) group and primary arthrodesis group. Ninety two patients were performed by ORIF, while primary arthrodesis group including 34 cases. Outcome measures included clinical examination, radiographs, AOFAS ankle-hindfoot scores, visual analogue scale (VAS) and SF-36 scores. Complications and revision rate were analyzed as well. Results: 126 patients were followed up for 29.5 months. At 1.5 years postoperatively, the AOFAS score was 79 and 85 in ORIF group and arthrodesis group.The VAS score was 3.1 separately in two groups.The mean Physical Functioning sores of SF-36 was 80.3 points and 83.5• points. The Bodily Pain score of SF-36 was 76.1 points and 84.6• points.Redislocation of first tarsometarsal joint were observed in 16 cases among ORIF group.36 patients in ORIF group had pain in midfoot, eight of them had persistent pain with the development of deformity or osteoarthrosis.No redislocation and no hardware failure was identified in arthrodesis group Conclusion: Primary stable arthrodesis of the first ray gives a better short and medium term outcome than open reduction and internal fixation for Lisfranc injury with the first ray dislocation. Possible complication and revision could be avoided by primary arthrodesis for dislocated first ray injuries.
