Occult Osseous Injuries After Ankle Sprains: Incidence, Location, Pattern, and Age

Abstract

We retrospectively evaluated 109 magnetic resonance studies in patients with prior ankle sprains to investigate the frequency and pattern of bone bruises. Patterns of bone bruises were then correlated with the ligaments injured. In addition, the age of the injury was determined from medical records to correlate the presence of bone bruises with the temporal period from injury. Bone bruises occurred in 39% of ankle sprains. Multiple bone bruises were seen in 40% of those with bone bruises; they occurred more frequently in patients with multiple ligaments injured. The marrow changes may be secondary to impaction, rotary instability of the ankle, and microavulsion vectors. Bone bruise-like lesions were seen at an average of 8.4 weeks in age but were seen more than a year after the injury. We conclude that bone bruises frequently occur in patients with ankle sprains, and the marrow changes may be caused by one of the three proposed mechanisms.

Clinical and imaging features of suspected prodromal fracture of the proximal phalanx in three Thoroughbred racehorses

“…1989), bone contusions (Stafford et al. 1986) and occult bone lesions (Labovitz and Schweitzer 1998). The most widely used term‐bone marrow oedema (BMO)‐is a histopathological term used to describe the replacement of bone marrow fat by material containing hydrogen ions, in the form of water (Alanen et al.…”

“…In both human and veterinary medical imaging, a number of synonyms have been used to describe the combination of bone marrow signal alterations seen in the cases described here. These terms include bone bruises (Yao and Lee 1988) bone marrow oedema (BMO) (Wilson et al 1988;Berger et al 1989), bone contusions (Stafford et al 1986) and occult bone lesions (Labovitz and Schweitzer 1998). The most widely used term-bone marrow oedema (BMO)-is a histopathological term used to describe the replacement of bone marrow fat by material containing hydrogen ions, in the form of water (Alanen et al 1998;Peterfy 2004) but has been used by clinicians as a generic diagnostic term for what is an imaging observation with a wide diagnostic differential, both traumatic and nontraumatic in origin.…”

Prospective study on diagnostic strategies in osteochondral lesions of the talus

“…29,30,43 We found five kissing lesions in 104 ankles (5%), which is comparable with findings in other studies. 44 Diagnostic arthroscopy was statistically significantly better than HPX and the mortise view. However, it did not show better results than helical CT or MRI in detecting or excluding an OLT.…”

Osseous abnormalities associated with collateral desmopathy of the distal interphalangeal joint: Part 1

“…Osseous trauma can be identified using MRI, characterised by an area of high signal intensity in the femur or tibia in fat suppressed images. Similar osseous lesions, sometimes referred to as 'bone bruises', occur in association with ligamentous injuries of the ankle (Labovitz and Schweitzer 1998). Similar lesions have been documented in horses associated with CL injury of the DIP joint (Dyson and Murray 2007c), but their frequency of occurrence is not known.…”
