摘要
Objective: To investigate the characteristics and damage area of the articular surface of the first/second tarsometatarsal joint to improve the treatment of the Lisfranc injury. Methods: Twenty fresh foot specimens of normal adults were dissected and divided into two groups. Results: In the group with one screw penetration, the ratio of damage area to distal articular surface of the first metatarsal and medial cuneiform bones were 5.11% and 4.65%, respectively; the ratio of damage area to distal articular surface of the second metatarsal and the middle cuneiform bones were 7.44 +/- 0.86% and 9.41 +/- 0.45%, respectively. In the group with two screw penetration, the ratio of damage area to distal articular surface of the first metatarsal and medial cuneiform bones were 10.22 +/- 0.67% and 9.30 +/- 0.32%, respectively, and the ratio of the damage area to the articular surface of the second metatarsal and middle cuneiform bones were 7.44 +/- 0.86% and 9.41 +/- 0.45%, respectively. For six feet, the ratio of the damage area caused by the screw through the second metatarsal base and middle cuneiform bones to the distal articular surface were 13.32 + 0.38% and 17.48 + 0.84%, respectively. Conclusion: The articular area of medial cuneiform bone is larger than that of the first metatarsal, and the articular area of the middle cuneiform bone is slightly smaller than that of the second metatarsal. The screw guide pin should be implanted successfully for the first time in the treatment of tarsometatarsal joint injury, because repeated adjustment may cause serious injury to the articular surface.
