A method, machine-readable storage medium embodying computer-readable code and automated system for assaying or monitoring the extent of joint or bone deformity reported by a summarized score that may include joint space narrowing, bone erosion and periarticular osteoporosis in a joint-degenerative or joint-damaging disease in a subject are disclosed. From a digitized image of one of the subject's straight bone terminated with a joint such as fingers, coordinates of right and left bone contours of a selected middle or proximal phalange are determined, and these coordinates are in turn used to determine the coordinates of a minimum width in the middle region of the phalange and one or more apices in a region adjacent at least one side of a joint of the selected phalange. These latter coordinates are used in selecting a reference joint contour representing normal-bone contour for that phalange, or the contour of the patient phalange from an earlier x-ray image. Guided by the reference joint contour, a region of the selected joint of the patient is analyzed to assay or monitor the extent of joint or bone deformity in the subject.

Instruments, implants, bone plates, systems and methods for correcting bone deformities and fractures in the lower extremity are disclosed. Specifically, targeting instruments, implants, bone plates, systems and methods used for correcting bone deformities and/or fractures in the foot are disclosed.

A method of correcting a bone deformity includes fixing first and second support members to first and second fragments of a bone, respectively. The first support member may have a receiver connected thereto. First and second tracking devices are connected to the first and second bone fragments, respectively. A deformity correction plan is determined, and a position of the first support member is adjusted relative to the second support member based on the plan. Location data is transmitted from the first and second trackers to the receiver. Based on the tracker location data, a real position of the first and second bone fragments is determined. The real position of the first and second bone fragment is compared to the deformity correction plan, and the deformity correction plan is reprogrammed based on the comparison. The first and second support members may then be adjusted based on the reprogrammed deformity correction plan.

Described herein are methods sand devices for the correction and reduction of bone deformities, such as metatarsus primus adductus, using a tethering technique which does not require drilling into the stable bone. In some embodiments, a bone plate has an elongate plate body and wings extending laterally from the plate body. The wings may be configured to generally follow the circumferential contours of the bone when placed on the bone in use. The bone plate can further include means for positioning cerclage material on the bone plate such that the cerclage material extends circumferentially over the wings rather than on the bone, thereby reducing the total contact area between the cerclage material and the bone.

The invention relates to a three-branched chain parallel external fixation device adopting annular adjustment. The three-branched chain parallel external fixation device comprises a near end ring, a far end ring, a hook joint, a spherical hinge, telescopic branched chains, annular guide rails, adjusting hand wheels, adjusting knobs, kirschner wires and a locking wire chucks. Through kirschner wires, the near end ring and the far end ring of the external fixation device are perpendicularly and rigidly fixed to a deformable bone separately, the annular guide rails are arranged on the near end ring and the far end ring respectively, the adjusting hand wheels are connected with sliding blocks on the annular guide rails, the adjusting knobs are installed on the telescopic branched chains, through the adjusting hand wheels and the adjusting knobs, the sliding blocks move around the annular guide rails, meanwhile, the telescopic branched chains extend or retract, and therefore the three-branched parallel external fixation device realizes 6-DOF movement and can correct any spatial three-dimensional bone deformity. The three-branched chain design is adopted, the annular guide rails are arranged, a 3-PUPS parallel structure is formed, and the three-branched chain parallel external fixation device has the advantages of being simple in structure, large in work space and flexible to operate, being provided with a few movement chains, and not being interfered easily.

The present invention is a method and device for the correction and reduction of bone deformities, such as metatarsus primus adductus, using a plate body with winged buttresses and dorsal loop. The method and device can be affixed to a bone without any drilling or violating of the bone and can use a tethering technique which does not require drilling into the second metatarsal, nor does it require the placement of a prominent suture knot/button device medially along the first metatarsal.

Described herein are external fixation systems for correcting bone deformities in adjacent bones or fragments thereof. The systems herein include first and second elongate tubes that translate with respect to one another via rotation of an actuation member at an end of one of the rods. At least one housing member is coupled along a length of one of the tubes. The housing member includes at least clamping portion for clamping a portion of a fixation pin therein. When the housing member is in an unlocked state, the clamping portions can move in a variety of directions. When in a locked state, the housing member cannot move with respect to the tube that it is coupled to. The position and orientation of the fixation pin is also set. The locked and unlocked state of the housing member is determined by the positioning of a locking pin coupled to the housing member.

A device and method for preventing and correcting abnormal shaping of an infant's cranium by applying external forces over time with the growth of an infant to achieve normal shaping of the infant's head. The device is a cranial orthosis having a depression with a contact surface in the shape of at least a portion of a normal infantile cranium. The orthosis further provides lateral support surfaces creating points of contact to restrict rotation of the infant's cranium and provide additional external forces for normal shaping of the infant's cranium. Because the present invention is non-conforming to the shape of an abnormal skull, the exerted forces cause accelerated expansion of the skull in less prominent areas coincident with brain and skull growth.
