1. A transdermal implant assembly for attaching an external prosthesis to a bone of a patient, the transdermal implant assembly comprising:
- a transdermal bone fixator configured for anchoring into a recess of the bone, the transdermal bone fixator including;
a longitudinally extending shaft configured to be received into the recess of the bone;
a spindle defining a cavity, the spindle having a proximal end and a distal end, wherein the distal end extends a distance past a dermis layer of the patient and is exposed to an environment external from the patient;
a compliant biasing member disposed within the cavity; and
an end cap removably coupled to the spindle and configured to seal the cavity;
a prosthesis adapter coupled to the spindle and configured for connection to an external prosthetic device that is operable for use with the bone,wherein the compliant biasing member is accessible upon removal of the end cap for adjustments from the external environment.

Abstract
A transdermal implant assembly including a transdermal bone fixator configured for anchoring into a bone. The fixator includes a longitudinally extending shaft configured to be received into a recess of the bone, and a spindle defining a cavity. A compliant biasing member is disposed within the cavity and an end cap is removably coupled to the spindle to seal the cavity. The compliant biasing member is accessible for adjustments from the external environment.

16. A transdermal implant assembly for attaching an external prosthesis to a bone of a patient, the transdermal implant assembly comprising:
-
an anchor disposed in and secured to a recess formed in the bone, the anchor including a longitudinally extending stem; a transdermal bone fixator coupled to the anchor, the transdermal bone fixator including; a longitudinally extending shaft configured to be received into the recess formed in the bone; a spindle defining a cavity, the spindle having a proximal end and a distal end, wherein the distal end extends a distance past a dermis layer of the patient and is exposed to an environment external from the bone of the patient; a compliant biasing member disposed within the cavity, wherein the compliant biasing member is pre-stressed and configured to provide a compressive force to the bone; an adjustment member disposed in the cavity and threadably coupled to the longitudinally extending anchor stem, the adjustment member being accessible from the external environment for adjusting the compliant biasing member without removing the spindle; a prosthesis adapter coupled to the spindle and configured for connection to an external prosthetic device that is operable for use with the bone. - View Dependent Claims (17, 18, 19)

20. A method of implanting a transdermal implant assembly into a patient, the method comprising:
- exposing and preparing a bone to receive a transdermal bone fixator;
the transdermal bone fixator comprising;
a longitudinally extending shaft configured to be received into the bone; and
a spindle having a proximal end and a distal end, wherein the distal end is configured to extend a distance past a dermis layer of the patient;
a compliant biasing member disposed within an interior of the spindle;
implanting the shaft of the transdermal bone fixator into the bone;
exposing at least a portion of the spindle to an environment external from the patient;
setting the compliant biasing member to exert a first force;
monitoring the force of the compliant biasing member; and
accessing the interior of the spindle and adjusting the compliant biasing member to exert a second force after the transdermal implant assembly is implanted in the bone of the patient. - View Dependent Claims (21, 22, 23)
