    - is X-linked recessive dystrophy that shares many of the features of DMD, including pseudohypertrophy of muscles;
    - main clinical difference is that the course is more protracted;
    - patients are usually able to walk as late as early adulthood and often live into their 30s and 40s;

- Lower Extremities:
    - equinus deformities & toe-walking are common;
    - consider Vulpius heel-cord lengthening, performed in conjunction, if needed, with a posterior tibial-tendon transfer
