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.

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 […]

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 […]

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 […]

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. […]

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 […]

One of the most common finger injuries is a tear of the ulnar collateral ligament of the thumb at the metacarpal phalangeal joint. In the distant past, this was referred to as gamekeeper’s thumb. This was described in Scottish gamekeepers due to a repetitive injury of the ulnar collateral ligament by the gamekeepers placing stress across the MCP joint while breaking the necks of […]

Glenoid dysplasia is a developmental anomaly of the scapula that results in bony deficiency of the posteroinferior glenoid. The normal glenoid labrum is shaped like a wine glass, with the bony margin extending to both edges. In glenoid dysplasia (also called glenoid hypoplasia or posterior glenoid rim deficiency) there is hypoplasia of the posterior bony glenoid. Since the bone is deficient posteriorly, there is […]
