MRI NEWSLETTER: The Spring Ligament, PTT Tear and Adult Acquired Flatfoot Deformity on MRI

Posted May 12, 2017

The posterior tibial tendon is the primary stabilizer of the foot. Other stabilizers include the spring ligament, the tarsal sinus ligaments and plantar fascia. The spring ligament complex consists of the tibio-spring component of the deltoid ligament and the calcaneonavicular ligament , which limits plantar flexion of the talus and stabilizes the talocalcaneal navicular joint. The tarsal sinus ligaments (cervical and interosseous ligaments) limit […]

MRI NEWSLETTER: Tarsal Coalition on MR

Posted April 20, 2017

Tarsal coalition is a congenital anomaly with fusion of the tarsal bones. The fusion may be bony, fibrous or cartilaginous. The most common tarsal coalitions are the calcaneonavicular and the talocalcaneal coalition. Tarsal coalitions often lead to painful foot, frequent ankle sprain, flat foot deformity and hindfoot valgus. This may lead to peroneal spastic flat foot. Calcaneonavicular coalition ossifies early and develops symptoms at […]

MRI NEWSLETTER: MR of the Bipartite Patella

Posted April 10, 2017

The bipartite patella is a normal patellar variant secondary to failure of fusion. Bipartite patella is often confused with a patellar fracture. Bipartite patella occurs in 8% of the population, is much more common in males 9:1, and bilateral in 50-80%. Bipartite patella occur most commonly in the superior- lateral location, 75% of cases. Bipartite patella is usually asymptomatic and found incidentally with only 2% […]

MRI NEWSLETTER: High Incidence of CAM FAI in Athletes

Posted April 4, 2017

Recent studies of FAI reveal the very high incidence of cam deformity (femoral neck bump) in Athletes. The cam deformity is a major risk factor for osteoarthritis of the hip and labral tears. More than half of the athletes studied, average age 25, had evidence of cam deformity as compared to only 23% of age-matched controls. In one study, cam deformities gradually developed during […]

MRI NEWSLETTER: Flexor Pulley Injury in Rock Climbers

Posted April 4, 2017

Injuries are most common in rock climbing and other sports resulting in a forced extension of a flexed finger. Approximately 30% of all hand injuries in rock climbers are pulley injuries. Findings on MRI include; focal discontinuity of pulley fibres, bowstringing – increased gap between the flexor tendon and volar surface of the phalanx, edema superficial and deep to pulley, fluid within tendon sheath. Read […]

MRI NEWSLETTER: Posterior Medial Corner Injuries of the Knee

Posted April 4, 2017

The posterior third of the posterior medial corner is made up of: – the posterior oblique ligament (POL) – the oblique popliteal ligament (OPL) – the posterior third of the medial meniscus the semi-membranous tendon (SM) The surgeons frequently ask if the POL is injured in posterior medial corner injuries. The posterior third of the posterior medial corner is made up of: – the […]

MRI NEWSLETTER: Meniscal Root Tears

Posted April 4, 2017

Meniscal root tears were not reported in the literature 10 years ago but recently have become increasingly important in both radiology and orthopedics. The meniscal roots are the primary structural anchors of both the medial and the lateral meniscus to the tibial plateau. As you can see in diagram below, the posterior roots of both the lateral and medial meniscal roots are anterior to […]

MRI NEWSLETTER: Painful Os Peroneum Syndrome

Posted April 4, 2017

The lateral ankle tendons include the peroneus brevis (PB) and peroneus longus (PL) tendons, which serve to evert the foot. These 2 tendons share the same tendon sheath proximally at the superior peroneal retinacula (SPR), but separate distally into two sheaths at the inferior peroneal retinacula (IPR). There brevis is located anterior to the longus. These tendons run in the retromalleolar groove on the […]

MRI NEWSLETTER Sinus Tarsi Syndrome

Posted April 4, 2017

Sinus tarsi syndrome is an inflammatory condition causing lateral hindfoot pain and instability. The most common cause for the syndrome is ankle trauma (about 70%) in particular an inversion injury, which can be treated with steroid injection into the sinus tarsi. A more serious cause of sinus tarsi syndrome is posterior tibial tendon dysfunction and spring ligament tears which frequently lead to the syndrome. […]

MRI NEWSLETTER: Stener-like Lesion of the Medial Collateral Ligament of the Knee

Posted April 4, 2017

An injury of the MCL is one of the most common ligamentous injuries of the knee. MCL injuries are graded 1-3, with grade 1 consisting of edema next to the MCL, Grade 2 with abnormal signal within the tendon, and Grade 3 with disruption of the tendon. Most disruptions occur at the proximal end (femoral avulsion) or mid-portion of the MCL. The vast majority […]
