Relative contraindications include previous infection, ligamentous
instability, subluxation of the talus, and mechanical malalignment.
Maiotti and colleagues (42) recommended using arthroscopic thermal capsular shrinkage for chronic ankle instability without ligamentous
8) Specifically, a lesser arc injury represents a pure ligamentous
injury around the lunate, and a greater arc injury involves the bones around the lunate (Fig.
MRI of ligamentous
and soft tissue injury in the cervical spine.
This destructive synovitis progresses to bone erosion and ligamentous
laxity, ultimately leading to instability and subluxation of the cervical spine.
The investigators suggested early operative treatment of unstable concomitant ligamentous
injury that was identifiable on plain radiographs.
Continued external rotation of the ilium may tear the anterior SI ligamentous
structures until the PSISs abut.
3) In reflex response time studies, the results seem to point to ligamentous
laxity, or a lack of ligamentous
integrity or malalignment of the ankle joint with excessive range of motion as the cause of functional instability, rather than to any deficit in reflex response time (Johnson and Johnson, 1993);
Compared to type I fractures, the aforementioned ligamentous
insertions are less likely to be attached to the condylar fragment.
Current indications for elbow MR arthrography include evaluation of the ligamentous
structures and depiction of articular hyaline cartilage defects.
Fractures and ligamentous
injuries of the clavicle and its articulation.
Management of spine injuries: absolute contraindications for return to play Cervical cord neurapraxia Single neurapraxic event with evidence of cord damage Ligamentous
instability Multiple episodes Episodes with symptoms lasting more than 36 hours "Stingers" Persistent neck pain Loss of motion Neurologic deficit Evidence of cervical myelopathy Principles and Guidelines 1.
