Lisfracs Injury
The Lisfranc joint complex is the midfoot joint that formed between bases of all metatarsals, cuneiform and cuboid. This joint complex is very important in maintaining the foot arch, transferring the body weight and muscle pull created by calf muscle from hind and midfoot to forefoot. These joints are held together by different ligament complexes and bone configuration similarly like ‘ROMAN ARCH’ and maintain foot arch.
Injury of this joint ranges from simple sprain and strain of these ligaments to major fracture of these bones and dislocation of the joints. Injury usually happens twisting the foot when indirect rotational and axial loading force passes through the hyper-plantarflexed forefoot.
Obvious injury is diagnosed easily because of its clinical presentation. But for subtle injury it requires a high degree of suspicion and clinical acumen. Only x-ray is not enough for proper evaluation of this injury, CT scan and MRI or both may require.
Recommended treatment is always operative for obvious fracture. Even most of the subtle injuries also require operative treatment because of the high incidence of disability. Foot arch can collapse and the flat foot can develop if the injury is neglected.
