First toe pain in a professional football player • Xray of the Week
First toe pain in a 30 y/o professional football player. What is the diagnosis?
Figure 1. Sagittal T1 (A) and "fat sat" (B) images show a tear of the tibial sesamoid phalangeal ligament (red arrow). The tear is a complete tear (grade III) with retraction of the tibial sesamoid.
Figure 2. Sagittal “fat sat” images show a normal (green arrow) and a torn (red arrow) sesamoid phalangeal ligament.
Figure 3. Axial “fat sat” images show a normal (green arrow) and a torn (red arrow) sesamoid phalangeal ligament.
Figure 4. This football player is at high risk for turf toe. Note the hyperextension of the first metatarsal phalangeal joint (insert) and the massive downward pressure by the opposing player.
Figure 5. Accelerated arthrosis in a 27 year old with chronic turf toe. Sagittal (A) and coronal (B) images show a shortened scarred sesamoid phalangeal ligament (red arrow) and a chronic osteochondral defect of the first metatarsal head (green arrows).
Turf toe is a tear of the sesamoid phalangeal ligament [Figs. 1-3]. The mechanism of injury in the acute setting is a hyperextension of the first metatarsal phalangeal joint when the hallux is fixed in equinus [Fig.4]. Chronic tear may occur with hyperextension or repeatedly pushing off when running or jumping. Playing football especially on artificial turf is a predisposing factor. Significant morbidity can occur with up to half of patients still symptomatic at 5 years. Most cases are managed conservatively with ice, elevation, and NSAIDS. Immobilization is used in higher grade injuries. However, surgery may be needed for failed conservative management or if there are complications such as sesamoid fracture, bipartite sesamoid separation, sesamoid proximal migration, instability with pain/synovitis, hallux rigidus, or an unstable chondral flap of the first metatarsal phalangeal joint [Fig.5].
