Understanding Liz Frank Injuries
A Liz Frank injury refers to disruptions in the tarsal-metatarsal articulation, which can range from minor subluxation to complete fractures and dislocations. These injuries are uncommon, accounting for only about 0.2% of all fractures, with a notably higher incidence in males in their 20s. The challenge lies in their frequent misdiagnosis, as 20 to 50% of cases are initially overlooked due to subtle or absent findings on x-rays. Early diagnosis is crucial, as delays can lead to considerable long-term complications like arthritis and chronic pain.
