FIGURE 37.1
T2-weighted MRI of the knee of a 24-year-old
patient with type I OI with a torn ACL. Although the torn ACL is
not visible, a peripheral meniscus tear and degeneration with bone
edema are observed.

the latter of which is detectable via X-ray diffraction.

Differences in tendon biomechanical strength became
apparent at high levels of strain.

Ligament injuries are even less frequently reported
than tendon injuries, perhaps due to decreased injury
severity. However, medial collateral ligament

and
anterior cruciate ligament (ACL) tears (
Figure 37.1
)
have been reported.

CONCLUSION
[16]
Muscle, tendon and ligament pathologies affecting
both the lower and upper extremities are seen in OI
patients. Ruptured Achilles tendons, anterior cruciate
ligament tears and shoulder injuries due to constant
wheelchair use are not uncommon in the OI population.
Within this patient population, allograft-assisted surgi-
cal repair of similar injuries has been successful.
