Systems and methods for limb support

An orthotic device, comprising:

• a hard or hardenable cast suitable for application to a limb of a patient;
• a footbed comprising an internal footbed, a sidewall portion, and an external sole;
• a first strut coupled to the footbed and/or the sidewall portion;
• a second strut coupled to the footbed and/or the sidewall portion;
• a paddle coupled to the first strut, the paddle comprising an inner surface configured to face the hard or hardenable cast as applied to the limb of the patient, wherein the inner surface comprises a mechanical interlock feature configured to minimize sliding of the paddle with respect to the hard or hardenable cast as applied to the limb;
• and
• a circumferential attachment system configured to interface with the paddle for tightening around the limb.

• and
• a foot support assembly comprising a first support layer and a second support layer located on the first support layer, wherein the first support layer is denser than the second support layer.

An orthotic device, comprising:

• a hard or hardenable cast suitable for application to a limb of a patient;
• a footbed comprising an internal footbed, a sidewall portion, and an external sole, wherein the internal footbed is substantially rigid and the external sole is an external rocker sole configured to permit ambulation;
• a foot support assembly, comprising a first support layer and a second support layer located on the first support layer, wherein the first support layer is denser than the second support layer;
• a first strut coupled to the footbed and/or the sidewall portion;
• a second strut coupled to the footbed and/or the sidewall portion;
• a paddle coupled to the first strut, the paddle comprising an inner surface configured to face the hard or hardenable cast as applied to the limb of the patient, wherein the inner surface comprises a mechanical interlock feature configured to minimize sliding of the paddle with respect to the hard or hardenable cast as applied to the limb;
• and
• a circumferential attachment system configured to interface with the paddle for tightening around the limb, wherein the circumferential attachment system comprises a strap coupling system.

A method for treating an ulcer or injury to the plantar area of a foot of a patient, comprising:

• providing the patient with an orthotic device comprising:
• a footbed comprising an internal footbed and an external sole, wherein the internal footbed is substantially rigid;
• a first strut coupled to the footbed;
• a second strut coupled to the footbed;
• a paddle coupled to the first strut, the paddle comprising an inner surface configured to face a limb of the patient having a hard cast applied thereto;
• a first support layer located on the footbed, the first support layer comprising a first aperture;
• and
• a second support layer located on the first support layer, the second support layer comprising a second aperture larger than the first aperture and at least partially overlapping the first aperture, wherein the first support layer is denser than the second support layer,
• wherein the first and second apertures are configured to circumscribe the ulcer or injury to the plantar area of the foot of the patient.
