Systems and methods for electromagnetic (EM) distortion detection and compensation are disclosed. In one aspect, the system includes an instrument, the system configured to: determine a reference position of the distal end of the instrument at a first time based on EM location data, determine that the distal end of the instrument at a second time is static, and determine that the EM location data at the second time is indicative of a position of the distal end of the instrument having changed from the reference position by greater than a threshold distance. The system is further configured to: determine a current offset based on the distance between the position at the second time and the reference position at the first time, and determine a compensated position of the distal end of the instrument based on the EM location data and the current offset.

A support system for positioning a patient in lateral position during surgery procedures with a removable, adjustable support pad assembly, comprising a first support unit arranged for attachment to side rail on a lateral edge of an operating table, and a second support unit comprising an arm connected movably by the using of a movable connection with a pad plate adapted to position a support pad connected by a biasing connector to a support plate with degrees of freedom of angular rotational movement of the support pad in relation to the patient. The biasing connector comprises a channel formed between a base plate support segment and a projection clamping the pad plate apart from the support plate to allow flow of air and/or fluids from the support pad.

A surgical positioner system for a support table having a side rail having a clamp assembly for attaching to the side rail. The clamp assembly having a spring and a locking assembly with movement in the x- and y-plane; and extension provides sliding movement in the z-plane. The extension being dimensioned to be operably connected to said clamp assembly and a rotational assembly. A rotational assembly has a portion for operably connecting to the extension, a device attachment portion, and a rotational assembly operably connected to the device attachment portion for providing rotational thereof. A boot having a holder portion and a flexible attachment can be attached to the device attachment portion. The surgical positioner provides motion from different force factors causing multiple components to move in a coordinated way using such established pivots and useful in performing various surgical procedures including direct anterior approach total hip replacement surgery.

A foot holding assembly that includes 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. The slider block includes a segmented body including 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 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.

A surgical frame and method for use thereof is provided. The surgical frame is capable of reconfiguration before, during, or after surgery. The surgical frame includes a main beam that can be rotated, raised/lowered, and tilted upwardly/downwardly to afford positioning and repositioning of a patient supported thereon. The surgical frame also includes a pelvic support for supporting a patient during movement of the main beam. The pelvic support is articulable between at least a retracted first position where the pelvic support is withdrawn from the pelvic area of the patient, and an extended second position where the pelvic area is supported thereby.

An apparatus comprises means for engaging a patient platform. The means comprises at least one layer of laminar sheeting of radiolucent material. At least one anatomical support member which comprises at least one layer of laminar sheeting of radiolucent material. At least one articulating joint unit is in engagement with the at least one of anatomical support member. The at least one articulating joint unit comprise at least one layer of laminar sheeting of radiolucent material with a primarily non-metallic connector at a central pivot point. The at least one articulating joint unit is positionable in at least a vertical and horizontal orientations enabling positioning of portions of an anatomy in three dimensions along x, y, and z axes. At least one primarily non-metallic locking member is configured to lock the at least one articulating joint unit at selectable position(s), in which a load bearing stress is spread across lengths of the laminar sheeting to mitigate a susceptibility to stress fractures and load failure.

Systems and devices oriented in a compact manner provide lift assistance to a spar of a surgery table for hip, leg-related surgeries, or generally lower limb related orthopedic procedures. The compact device does not impede the radiolucency of the spar below the patient's hip, trochanter, or femur.

A patient support device includes an alternate support top, a head support unit partially supporting the alternate support top, a foot support unit longitudinally spaced from the head support unit and an adaptor associated with the foot support unit. The adaptor is securable to the foot support unit so that the adaptor and foot support unit cooperate to partially support the alternate support top so that the alternate support top extends footwardly beyond the foot support unit. The roles of the head and foot support units may be reversed. A related patient support system includes a baseline set of support tops and a set of alternate support tops.

Rotation unit (16) for connecting to an operating table for rotation of a patient's leg about its longitudinal axis, wherein the rotation unit (16) comprises: an interface (24) for attachment of the foot of the patient's leg on the rotation unit (16); a rotor, to which the interface (24) is connected in a torsionally resistant manner and which is used for rotation of the interface (24) and thus of the patient's leg about the longitudinal axis; a stator (42), on which the rotor is rotatably mounted, such that the rotor can rotate relative to the stator; a rotary handle (22) for rotation of the rotor; and a locking assembly (26) for blocking the rotation of the rotor relative to the stator. The locking assembly (26) can be actuated by means of an action on the rotary handle.
