Turf toe is a term used to describe myriad injuries to the metatarsophalangeal complex of the great toe, which have been associated with the introduction of artificial turf surfaces in sport. If not diagnosed early and treated properly, these injuries can result in chronic pain and loss of mobility. Accurate injury grading through physical exam and advanced imaging is essential to guide treatment, thereby minimizing long-term complications and maximizing an athlete’s recovery and return to play.

“…Previous reports [ 19 , 20 ] showed that the plantar plate of the first MTPJ differed from that of the lesser ones (2–5) in that it spanned between the proximal phalangeal base and metatarsal head with the intervening hallux sesamoids. There are discrepancies when describing the components of the plantar plate [ 11 , 13 , 16 , 21 – 25 ]. Some studies [ 2 , 15 ] reported that the plantar plate arose from the distal margin of the intersesamoid ligament and extended distally toward the base of the proximal phalanx.…”

High-resolution 3T magnetic resonance imaging and histological analysis of capsuloligamentous complex of the first metatarsophalangeal joint

Background There are discrepancies in the understanding of the structure of the capsuloligamentous complex of the first metatarsophalangeal joint (MTPJ); this study aims to investigate the differences with previous anatomical reports of high-resolution 3T magnetic resonance imaging (MRI) and histological analysis in illustrating the structure of the capsuloligamentous complex of the first MTPJ. Methods Nine fresh frozen cadaveric feet specimens (from two women and three men; aged 32 to 58 years) were used in this study. All specimens underwent MR examination with T1-weighted imaging and T2-weighted spectral attenuated inversion recovery in three planes. Subsequently, all cadaveric feet specimens were sliced into 2-mm-thick sections. The MRI features of the capsuloligamentous complex of the first MTPJ were analyzed in these specimens. Hematoxylin–eosin and Masson’s trichrome staining methods were used to explore the histologic features of the capsuloligamentous complex of the first MTPJ. Results Different from most previous studies, our results showed that the plantar plate could be divided into four portions including the central portion of the plantar plate, the intersesamoid, the sesamoid phalangeal and the metatarsosesamoid ligaments. The normal central portion of the plantar plate could be clearly visualized in the sagittal and coronal plane MR images. The intersesamoid ligament is a continuation of the central portion of the plantar plate on the sagittal plane on the gross specimen, the MR imaging, and the histological examination. On the coronal plane of the gross specimen and MR imaging, the sesamoid phalangeal ligaments and the central portion of the plantar plate can be seen as separate ligaments, but they appeared interwoven with the same continuous collagenous fibers on the histological analysis. Conclusion High-resolution 3T MRI allows accurate demonstration of the different anatomical details of the capsuloligamentous complex of the first MTPJ from previous anatomical reports. The histological analysis provides further understanding of the structures of the capsuloligamentous complex of the first MTPJ from previous studies.

“…Magnetic resonance imaging (MRI) can be useful in ambiguous cases; however, it needs to be interpreted with caution as they have been shown to overestimate the degree of injury. Dietrich et al obtained MRIs in 30 asymptomatic volunteers and found that the collateral ligaments frequently contained hyperintense areas on fluid-weighted sequences with fat suppression and on intermediate weighted sequences [12].…”

Toe injuries have been found to represent nearly 10% of injuries presenting to fracture clinics. While most injuries can be treated nonsurgically, there are a number of specific injuries that require a high index of suspicion, careful management, and in some cases, surgical intervention. Injuries detailed in this review include turf toe, traumatic bunion, and hallux and sesamoid fractures. Additional pathologies that are covered include sesamoiditis and sesamoid avascular necrosis as well as hallux rigidus. Appropriate workup and current treatment recommendations are discussed. Injuries to the hallux can result in long-term pain and disability if not properly diagnosed and treated. A high index of suspicion is required.
