A deformity, dysmorphism, or dysmorphic feature is a major abnormality in the shape of a body part or organ compared to the normal shape of that part.

Intramedullary locked compression screw for stabiliziation and union of complex ankle and subtalar deformities

An intramedullary lockable compression screw for stabilization and reconstruction of deformities of the ankle and subtalar joints, and which is particularly suitable for stabilization and fusion of the tibiotalar, talocalcaneal, tibiocalcaneal and / or tibiotalocalcaneal, is provided. The compression screw includes an elongated tubular member extending along a substantially straight first longitudinal axis between the leading end and the trailing end of the member. The tubular member includes a threaded leading end portion proximate the leading end, a threaded trailing end portion proximate to the trailing end, and an unthreaded shaft portion interconnecting the threaded leading end and the threaded trailing end portions. The diameter of the threaded leading end portion is smaller than the diameter of the threaded trailing end portion. A through-hole extends along a straight second longitudinal axis between a first opening, in a first area of an outer periphery of the tubular member proximate to the trailing end, and a second opening, in a second area of the outer periphery of the tubular member distal to the trailing end. The through hole is formed such that the second longitudinal axis intersects the first longitudinal axis at an angle of other than 90 degrees and so as to accommodate a locking screw.

Multi-adjustable plate for osteotomy

InactiveUS20120232596A1Shorten durationSimple techniqueBone platesAcute angleBiomedical engineering
The invention relates to a mechanical device intended for correcting a malformation of the bones of the body. The device is continuously adjustable, making the surgeon's work easier and reducing surgery time, thus reducing the risk of infection and, above all, guaranteeing the desired precision for surgery. The device comprises a top plate (1) suitable for sliding over a bottom plate (2) by means of a guide (7). Said plates can be screwed on either side of an angled notch made in the bone. The plates comprise respectively top (5) and bottom (6) bearings of the notch of the bone. Said bearings form an acute-angle bevel which substantially matches the surfaces of the notch. One of the plates is provided with an adjustment screw (4) for continuous adjustment of the relative positions of the plates. The device also comprises a locking screw (3) suitable for maintaining the open position of the device and, consequently, the final angle of the notch of the bone in the desired position. The Top bearing of the notch of the bone having angular adjustment is suitable for correcting the angle of the bevelled surface of the bearing, in particular the tibial slope, by means of a tapered screw (8) adjustment an angular space in the bearing.

Medical device and method to correct deformity

ActiveUS20090012565A1Correction of spinal deformitySuture equipmentsInternal osteosythesisEngineeringMedical device
A system for correcting a spinal deformity includes an implant fixed to one side of a vertebra and a rod extending along an axis of the spine on a second side of the vertebra. An adjustment member, which may include a reel, is coupled to the rod. A force directing member, such as a cable, extends between the rod and the adjustment member. The force directing member is retractable toward and extendible from the adjustment member. A method of correcting spinal deformity includes providing an implant, a rod, an adjustment member coupled to the rod, and a force directing member extending between the rod and the adjustment member. The adjustment member can be retractable toward and extendible from the adjustment member.

External fixation system and method of use

ActiveUS20070049930A1Distraction/reduction/compression of bone or bone segmentsMove quicklyInternal osteosythesisJoint implantsDistractionDeformity
An external fixation system for connecting one or more bone segments together to facilitate healing of bone. The system may include one or more rings and / or ring segments. One or more linear distractors and / or angular distractors may connect the rings to each other so as to allow for distraction and / or reduction / compression of a bone. Linear distractors may enable an operator to move the rings towards and away from each other, while angular distractors may enable an operator to angle the rings relative to each other. In an embodiment using angular distractors, one or more angular separation assemblies may be positioned between the rings. These separation assemblies may have joints which may two portions which may be angled relative to each other and connected directly or indirectly to the rings. Various fasteners (e.g., nuts) and / or tightening members may configured for quick movement along and selective tightening to various components. Moreover, clamps may be attached to the rings and may engage pins, wire, rods, which may be inserted into bone to hold bone segments to each other. The components of the external fixation system may be provided in sets or kits so that the a surgeon may select various combinations of components to create an external fixation system which is configured specifically for the particular needs of a patient and the bone fracture / deformity.
