An apparatus comprising a joint spacer for treatment of a joint of a human subject, the joint spacer comprising:
- a pouch having a wall comprising a dermal graft material, the wall having an average thickness between 1 and 4 mm;
- and
- a filling port for the pouch,
- wherein the pouch is configured to be inserted into a space of the joint and elastically inflated via the filling port,
- wherein when the pouch is inflated and the filling port is sealed, the inflated pouch remains intact when subjected to a force in a range from 400 N to 1000 N.
An apparatus comprising a joint spacer for treatment of a joint of a human subject, the joint spacer comprising:
- a pouch having a wall comprising a dermal graft material,
- wherein the joint spacer is configured to be inserted into a space of the joint and inflated to provide mechanical support to the joint,
- wherein the pouch is inflated with a volume of bone marrow.
A method for treating a joint of a human subject, the method comprising:
- inserting a joint spacer into a joint space, the joint spacer including a pouch having a wall comprising either a polymer interwoven into a dermal graft material or a polymer shaped as one or more separate layers that are fixed to a dermal graft material, the wall having an average thickness between 1 and 4 mm;
- elastically inflating the pouch within the joint by filling the pouch via a filling port of the pouch;
- and
- sealing the filling port of the pouch such that the inflated pouch remains intact when subjected to a force in a range from 400 N to 1000 N.
