Tarsometatarsalniveltyjä

"Tarsometatarsalniveltyjä" is a Finnish term that refers to injuries or dislocations affecting the tarsometatarsal joints of the foot. These joints, also known as Lisfranc joints, are formed by the articulation between the tarsal bones (primarily the medial cuneiform, intermediate cuneiform, and lateral cuneiform) and the bases of the metatarsal bones. This complex structure plays a crucial role in maintaining stability and enabling proper foot function during weight-bearing activities such as walking and running.

Injuries to the tarsometatarsal joints typically occur due to trauma, including falls, twisting injuries, or direct impacts. These injuries can range from mild sprains and ligament injuries to complete dislocations or fractures. Tarsometatarsal dislocations are often associated with significant pain, swelling, and difficulty bearing weight on the affected foot. Proper diagnosis usually involves clinical examination complemented by imaging techniques such as X-rays or MRI scans to assess bone alignment and soft tissue damage.

Treatment depends on the severity of the injury. Mild sprains may be managed with immobilization and rest, while dislocations or fractures often require surgical intervention to realign the bones and stabilize the joint using pins, screws, or plates. Untreated or improperly managed injuries can lead to chronic instability, deformity, or post-traumatic arthritis, which may impair foot function long-term.

Preventative measures include protective footwear and caution during high-impact activities. Understanding the anatomy and biomechanics of the tarsometatarsal joints is essential for accurate diagnosis and effective management of these injuries, promoting optimal recovery and preserving foot functionality.
