1. Cuboid Syndrome (2/2/10)

Background - Cuboid syndrome is a poorly defined clinical entity that describes acute and chronic lateral foot pain. Historically, cuboid syndrome has been described as a subluxation of the calcaneal cuboid joint. Radiographic classification of this subluxation has not been defined. Absence of a classification for radiographic findings of cuboid syndrome suggests that the classical description of cuboid syndrome may be anecdotal.

Hypothesis - MRI findings in patients with acute and chronic lateral column pain/cuboid syndrome suggests that cuboid syndrome may be caused by abrupt force applied to the cuboid by the peroneus longus tendon. This abrupt force applied to the cuboid results in a bone contusion. Abrupt force being applied to the cuboid would be common in a lateral ankle sprain. Incomplete healing of the bone contusion and repetitive stress applied by the peroneus longus tendon to the cuboid results in re-injury of the cuboid.

Study format - We are currently searching for individuals who have symptoms that have been diagnosed as cuboid syndrome and would like to participate in this study. Study participants need to meet the following criteria:

1. Have been treated and diagnosed with lateral column foot pain/cuboid syndrome during the past 2 years.

2. Have experienced acute pain and relapses of pain in the lateral column of the foot.

3. Have had both x-rays and MRI of the foot.

4. Live in The United States.

If you meet these criteria and are interested in participating in this study, please contact us at melissa@drjoster.com.

Topical Landmarks That May Be Used For EGR Surgery (12/22/09)

Background - A surgical approach is the term used to describe incision placement at the start of surgery. Defining correct surgical approach is important to enable access to the planned changes made by a particular surgery. In endoscopic surgical procedures, surgical approach is critical to the success of the procedure. Endoscopic gastrocnemius recession (EGR) is an endoscopic procedure that selectively releases one of the two calf muscles. Defining the surgical approach for EGR can be difficult based upon variation in body build (mesomorphic/endomorphic) and variations in anatomy.

Method - In this study we are reviewing 100 MRI studies of the calf, ankle and leg to define anatomical relationships that will enable surgeons to use topographical landmarks to clearly define the surgical approach for EGR.
