Described is a locking intramedullary nail for insertion in the medullary cavity of hollow bones for treating bone fractures or for joint stiffening. The nail comprises an oblong shaft having at least one holder for a locking screw. In the region of an opening a roller or ball-shaped sleeve having a bore for receiving the locking screw is arranged. The sleeve which is supported in the shaft in a freely pivotable manner can be locked in a positionally stable manner in the shaft. This affords the ability to introduce the locking screws during the implantation of the intramedullary nail at an optimum angle for the respective anatomical or pathological situation of the patient and to subsequently lock it permanently at a constant angle.

Described herein is a surgical nail in the form of an intramedullary nail with a central axis made from a material M with a tensile strength F.sub.z, compressive strength F.sub.d, density ρ.sub.2 and modulus of elasticity E. The nail has a transverse bore extending transversely to the central axis and having a cross-sectional profile F and a transverse axis, the cross-sectional profile F having a maximum length a that runs in the direction of the central axis and a maximum width b that runs perpendicular to the length. An insert with the longitudinal axis, made from material m and having a modulus of elasticity e that is smaller than the modulus of elasticity E of material M, can be introduced into the transverse bore. The insert also has a length L that runs in the direction of its longitudinal axis and satisfies the condition L>0.2 D.

The invention relates to an interlocking nail (10) for fixation of transverse and short spiral fractures of, long bone, particularly shaft of the femur, tibia and humerus, having Graft extrusion space/slot (101) for holding stem cells graft and 4 or 5 holes for putting interlocking bolts from lateral to medial direction. Constant compression achieved (irrespective of weight bearing cycle) at the fracture site by tightening of the Endo-Compression Screws (108, 109 and 110) results in stimulation of stem cells and reduction in bone gap, thus enhances bone healing and union manifolds.

An aspect of the disclosure relates to an intramedullary device configured for ankle fusion. The intramedullary device for ankle fusion includes: a housing configured to be coupled to a calcaneus bone; and a rod configured to be coupled to a tibia bone, wherein a distal end of the housing includes an external thread. The rod is configured for telescopic movement relative to the housing, and to retract relative to the housing to cause ankle fusion. After fusion is achieved, the rod can be distracted to correct a limb length discrepancy.

Aspects of the disclosure relate to an adjustable implant configured to be implanted into a patient that includes an adjustable portion moveable relative to a housing. The adjustable implant may include various smart components for enhancing operation of the implant. Smart components may include a controller for managing operations and a transducer for communicating ultrasound data with an external interface device. Additional smart components may include a load cell within the housing for measuring an imparted load; a sensor for measuring angular position of the adjustable portion; a dual sensor arrangement for measuring imparted forces; a reed switch; a half piezo transducer; and an energy harvester.

An intramedullary nail implant for positioning in a bone having a head and a shaft defining an intramedullary canal. The implant includes a distal portion having a shaft extending along a central axis and configured for positioning within the intramedullary canal. A proximal portion extends proximally from the distal portion. The proximal portion defines a contact surface which extends at least in part medially of the central axis such that it is configured to extend within a medial portion of the bone head. A method of implanting the nail is also provided.

Implants, systems and methods for correcting bone deformities and fractures in the lower extremity are disclosed. Specifically, implants, systems and methods used for correcting bone deformities and/or fractures in the foot using compression are disclosed. A nail system including a first member with a first deformable member positioned at a first end of the first member and a second member received within the first member.

The invention comprises a method for fixating bones in the foot by aligning the bones in their desired position, inserting a screw in the aligned bones, inserting at least one transverse element near the head or tip of the screw, and tightening the screw to compress the bones. The screw comprises a shaft having first and second ends with spirally wound screw threads beginning near the first end and extending along the shaft. Advantageously, the screw is cannulated and screw threads are formed on an interior surface of the cannulation. Illustratively, the transverse elements may be staples, open-ended washers, or open-ended nuts. Reduction instruments and drill guides used in the invention are also disclosed.

An implant system for use in orthopaedic surgery for fixation of bone includes an intramedullary nail and a coupling member. The intramedullary nail includes a proximal portion defining a longitudinal axis. The proximal portion includes an axial bore defining an axis substantially parallel to the longitudinal axis of the proximal portion and a transverse bore configured to receive a bone fastener. The coupling member includes a through hole and is movably arranged within the axial bore of the proximal portion. Further, the coupling member includes a drive portion and a bone fastener engagement portion. The drive portion is in one variant non-rotatably coupled to the bone fastener engagement portion. The bone fastener engagement portion is configured to engage the bone fastener penetrating the transverse bore. In one variant the engagement is realized via an extended contact region.

Devices, systems, and methods for bone stabilization, especially proximal humeral stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis and an enlarged head portion extending from the elongated portion. The stabilization system may include an intramedullary nail having an upper portion and a lower portion extending from the upper portion, the upper portion and the lower portion including a plurality of holes. A plurality of fasteners may be configured to extend through one or more of the plurality of through holes in the bone plate and/or one or more of the plurality of holes in the intramedullary nail and into the bone. The plate and nail may each be used alone or in combination together to stabilize a fracture in a long bone, such as a humerus.
