Lisfranc injuries affect the tarsometatarsal (TMT), intercuneiform, and the naviculocuneiform joints. It can be osseous, ligamentous, or a combination of the two. The major advance in the last decade has been the emphasis on early stable anatomical reduction and stabilisation of these injuries. Recent studies have suggested that primary arthrodesis may be a preferred technique for primarily ligamentous Lisfranc injuries. This study aimed to evaluate the short term results of primary arthrodesis in pure ligamentous lisfranc injuries. Twenty patients, 13 males and 7 females with a mean age of 27.4 ± 6.19 with minimum age 19 years old and maximum age 39 years old were included in this study. The most common mechanism of injury was road traffic accident (55%), followed by fall from height (40%), and followed by hyper plantar flexion foot trauma during descending stairs (5%). the mean AOFAS score of the included patients was 81.65 ± 1.60 with minimum score 80 and maximum score 84. the mean EFAS score of the included patients was 31.60 ± 1.76 with minimum score 28 and maximum score 34. the mean Pain VAS score of the included patients was 2.05 ± 0.76 with minimum score 1 and maximum score 3. the mean Union time of the included patients was 12.55 ± 0.51 weeks with minimum 12 weeks and maximum 13 weeks. In conclusion, Lisfranc injuries are complex and care must be taken in selecting the appropriate treatment. Primary arthrodesis in pure ligamentous lisfranc injury has advantages: reduced foot deformity rates, sustained biomechanical morphology of the feet, reduced complications, higher level of function recovery, shorter time of surgical procedures, fewer complications, higher AOFAS, EFAS, pain VAS scores, reduced plantar pain and decrease reoperation rates. The majority of the fusion patients had good results and osseous union. |
