Once the cuboid fracture is recognized, weight bearing views should be obtained to assess for occult ligamentous injury as well as CT scan to fully characterize the extent of the fracture and comminution. However, medial oblique views may better characterize the calcaneo-cuboid and metarocuboid articulations. DiagnosisĪP, lateral and oblique views of the foot are usually sufficient to diagnose cuboid fracture. This diagnosis should considered differential of athletically active patients presenting with chronic lateral foot pain. Similar to traumatic injuries, this injury is likely related to repetitive forced abduction of the forefoot. This presents lateral foot pain that radiates to the ankle and lateral metatarsals resulting in a sense of weakness in plantarflexion during push off. There is usually direct tenderness to palpation over the cuboid and difficulty with weight-bearing.Ĭuboid dislocation has been reported to occur in up to 9% of high performance athletes and 17% of ballet dancers and is termed cuboid syndrome. Swelling and ecchymosis over the cuboid should raise suspicion of this injury and when other midfoot injuries are present, the cuboid articulations should be carefully inspected for subtle injury. Subsequently, the fracture pattern unique to each subcategory is given a number.įractures of the cuboid can present with varying swelling and deformity of the lateral midfoot. This classifies cuboid fractures as 76 with A- extra-articular, B- involving either the calcaneocuboid joint or metatarsocuboid joint, C- involving both major joint surfaces. The OTA classification system may be used for research purposes. There is no commonly used classification system. The peroneus longus courses on the planar surface of the cuboid in a lateral to medial direction. The longitudinal plantar ligament provides strong support of the plantar aspect of the calcaneocuboid joint. Additionally, the fourth and fifth metatarso-cubiod joints allow up to three times more motion than the medial three metatarso-cunieform joints.

These articulations provide for nearly all of the mobility of the lateral column of the foot. Distally, it articulates with the fourth and fifth metatarsals.

Medially, it articulates with the navicular nad lateral cuneiform. Proximally, the cuboid has a saddle shaped articulation with the calcaneus. The cuboid makes up the midfoot's contribution to the lateral column of the foot and serves mainly as a lateral column spacer block. However, injuries to the cuboid may be subtle and can be misdiagnosed as lateral ankle sprains. Direct injuries occur by direct blow or high energy crush injuries. Indirect injury usually occurs through a torsional injury to the ankle and midfoot resulting in the cuboid being crushed between the calcaneus and metatarsals by forced plantar flexion and abduction. They can occur through direct or indirect mechanisms. Fractures of the cuboid can occur in isolation, but are often associated with other fractures and dislocations of the midfoot.
