and a retainer disposed at an lateral interface of the pair of longitudinal segments and the lateral segment, wherein the retainer is configured to receive a second end of the pivot arm; wherein the pair of longitudinal segments and the lateral segment of the segmented body are each configured to move relative to one another in response to insertion of the second end of the pivot arm into the retainer. ### Claim 2 (depends on 1) The foot holding assembly of claim 1, wherein the pair of longitudinal segments of the slider block are configured to move relative to each other along the lateral interface and orthogonal a central axis of the rail. ### Claim 3 (depends on 2) The foot holding assembly of claim 2, wherein the slider block further comprises a pivot arm release extending from one of the pair of longitudinal segments and comprising an open position permitting insertion removal of the second end of the pivot arm from the retainer and a closed position configured to restrict the removal of the second end of the pivot arm from the retainer. ### Claim 4 (depends on 3) The foot holding assembly of claim 3, wherein: the pair of longitudinal segments of the slider block are permitted to move relative to each other along the lateral interface and orthogonal a central axis of the rail when the pivot arm release is in the open position; and the pair of longitudinal segments of the slider block are restricted from moving relative to each other along the lateral interface and orthogonal the central axis of the rail when the pivot arm release is in the closed position. ### Claim 5 (depends on 2) The foot holding assembly of claim 2, wherein the lateral segment of the slider block is configured to move relative to the pair of longitudinal segments parallel to the central axis of the rail. ### Claim 6 (depends on 1) The foot holding assembly of claim 1, wherein the lateral segment of the slider block extends across a longitudinal interface formed between the pair of longitudinal segments and wherein the longitudinal interface extends parallel with a central axis of the rail. ### Claim 7 (depends on 1) The foot holding assembly of claim 1, wherein the slider block comprises a stop release extending from the lateral segment of the segmented body, and wherein the stop release is configured to selectably lock the slider block to the rail. ### Claim 8 A foot holding assembly for securing a foot of a patient during a surgical or diagnostic procedure, the assembly comprising: a boot configured to hold the foot of the patient; a rigid sole coupled to the boot; a pivot arm having a first end rotatably coupled to the sole; a slider block pivotally coupled to a second end of the pivot arm and configured to be slidably mounted to a rail, wherein the slider block comprises: a segmented body comprising a pair of longitudinal segments and a lateral segment; a retainer disposed at an lateral interface of the pair of longitudinal segments and the lateral segment, wherein the retainer is configured to receive a second end of the pivot arm; and a pivot arm release extending from one of the pair of longitudinal segments and comprising an open position permitting insertion removal of the second end of the pivot arm from the retainer and a closed position configured to restrict the removal of the second end of the pivot arm from the retainer. ### Claim 9 (depends on 8) The foot holder assembly of claim 8, wherein the pair of longitudinal segments of the slider block are permitted to move relative to each other along the lateral interface and orthogonal a central axis of the rail when the pivot arm release is in the open position. ### Claim 10 (depends on 9) The foot holder assembly of claim 9, wherein the pair of longitudinal segments of the slider block are restricted from moving relative to each other along the lateral interface and orthogonal the central axis of the rail when the pivot arm release is in the closed position. ### Claim 11 (depends on 8) The foot holder assembly of claim 8, wherein the pivot arm release of the slider block comprises a shaft extending into a first longitudinal segment of the pair of longitudinal segments and a slug extending into a second longitudinal segment of the pair of longitudinal segments, and wherein a threaded lateral interface is formed between the shaft and the slug. ### Claim 12 (depends on 8) The foot holder assembly of claim 8, wherein the lateral segment of the slider block is configured to move relative to the pair of longitudinal segments parallel to a central axis of the rail. ### Claim 13 (depends on 8) The foot holder assembly of claim 8, wherein the slider block further comprises a stop release extending from the lateral segment of the segmented body, and wherein the stop release is configured to selectably lock the slider block to the rail. ### Claim 14 (depends on 8) The foot holder assembly of claim 8, wherein the pair of longitudinal segments and the lateral segment of the slider block are each configured to move relative to one another in response to insertion of the second end of the pivot arm into the retainer when the pivot arm release is in the open position. ### Claim 15 A foot holding assembly for securing a foot of a patient during a surgical or diagnostic procedure, the assembly comprising: a boot configured to hold the foot of the patient; a rigid sole coupled to the boot; a pivot arm having a first end rotatably coupled to the sole; a slider block pivotally coupled to a second end of the pivot arm and configured to be slidably mounted to a rail, wherein the slider block comprises: a segmented body comprising a pair of longitudinal segments and a lateral segment; and a retainer disposed at an lateral interface of the pair of longitudinal segments and the lateral segment, wherein the retainer is configured to receive a second end of the pivot arm; wherein the pair of longitudinal segments are configured to move relative to each other along the lateral interface and orthogonal a central axis of the rail. ### Claim 16 (depends on 15) The foot holding assembly of claim 15, wherein the lateral interface of the slider block extends orthogonal the central axis of the rail. ### Claim 17 (depends on 16) The foot holding assembly of claim 16, wherein the lateral interface of the slider block comprises a tongue-in-groove lateral interface. ### Claim 18 (depends on 15) The foot holding assembly of claim 15, wherein the lateral segment of the slider block is configured to move relative to the pair of longitudinal segments parallel to the central axis of the rail. ### Claim 19 (depends on 15) The foot holding assembly of claim 15, wherein each of the pair of longitudinal segments of the slider block comprises a pivot about which the pair of longitudinal segments are configured to pivot. ### Claim 20 (depends on 15) The foot holding assembly of claim 15, wherein the slider block further comprises a pivot arm release extending from one of the pair of longitudinal segments and comprising an open position permitting insertion removal of the second end of the pivot arm from the retainer and a closed position configured to restrict the removal of the second end of the pivot arm from the retainer.
