A medical device can include a first anchor for attachment to a first bone fragment and a second anchor for attachment to a second bone fragment. The second anchor attachment can be coupled to the first anchor via a compression element between the first anchor and the second anchor. The medical device can include a resorbable element maintaining the first anchor and the second anchor at a first distance. The resorbable element can be configured to at least partially resorb after insertion into a patient. After the resorbable element is at least partially sorbed, the compression element forces the first anchor and / or the second anchor to translate such that the first anchor and the second anchor are at a second distance, thereby compressing the first bone fragment and the second bone fragment.

Disclosed herein are components, systems, and methods to secure an intramedullary implant to multiple fragments of a fractured bone and to secure an intramedullary implant to a fragment of a fractured bone using multiple modalities. The intramedullary implant includes a proximal body portion with transverse fixation holes positioned to receive bone fixators that secure a first bone fragment of the fractured bone to the intramedullary implant, a distal body portion with a deployable bone fixator that abuts an inner surface of a second bone fragment of the fractured bone, and a tapered intermediate body portion with a transverse fixation hole positioned to receive a bone fixator that secures the second bone fragment of the fractured bone to the intramedullary implant.

The present invention provides an osteosynthesis plate for fixing bone fragments in the repair of bone, particularly the mandible. [Solution] The invention comprises a plate body P, the plate body having an upper surface OS and a lower surface for positioning the plate body on bone fragments K1 and K2, the plate body having a plurality of fixing parts BA1 and BA2, the bone fixation plate OP being fixed to the bone fragments at the lower surface of the plurality of fixing parts, each of the plurality of fixing parts being associated with at least one fixing point BP1 and BP2, at least one fixing point of the fixing parts being formed on an island part IA, the island part being connected to the relevant fixing part of the plate body only via spring segments FS1 and FS2 that allow elastically restorable relative displacement between each fixing part and each island part, and the spring segments asymmetrically surrounding the fixing point associated with the spring segments.

Apparatuses and methods for a flexible obturator for use with an access assembly of an intraosseous device are disclosed. The flexible obturator can include elastic properties and a relatively low column strength, a relatively low shear strength, and / or a relatively high compression strength. The obturator can prevent bone chips and tissue from obstructing the needle lumen when the obturator is supported in the needle. When removed from the needle, the obturator can deform under force to prevent accidental needle sticks. The flexible obturator can define a radially symmetric profile and can conform to the interior profile of the needle lumen. The flexible obturator can extend beyond the distal tip of the needle and be trimmed to be flush with the bevel of the needle. This simplifies the manufacturing process, allowing a single size of obturator to fit multiple sizes of needles.

A surgical system can be configured to obtain image data of a joint that comprises at least a portion of a humerus; segment the image data to determine a shape for a diaphysis of the humerus; based on the determined shape of the diaphysis, determine an estimated pre-morbid shape of the humerus; based on the estimated shape of the humerus, identify one or more bone fragments in the image data; and based on the identified bone fragments in the image data, generate an output. 76 20 24 20 11 04 20 F eb 2 02 4 A B S T R A C T 2 0 2 4 2 0 1 1 0 4 2 0 F e b 2 0 2 4 7 6

Osteosynthesis plate (OP; OP'; OP''; OP'''), which is intended for fixing bone fragments (K1, K2) for the reconstruction of a bone (K), in particular a mandible, comprising a plate body (P; P') with a top (OS) and a bottom, on which the plate body (P; P') is to be placed on the bone fragments (K1, K2), wherein the plate body (P; P') has several attachment sections (BA1, BA2; BA1', BA2', BA3'), on which attachments of the osteosynthesis plate (OP; OP'; OP''; OP''') are to be made on the underside by the bone fragments (K1, K2) and to which at least one attachment point (BP1, BP2; BP1', BP2', BP3') is assigned, wherein the at least one attachment point (BP2; BP2', BP3') is located at at least one of the attachment sections (BA1, BA2; BA1', BA2', BA3') is designed on an island section (IA) which is connected to the associated fastening section (BA2; BA2', BA3') of the plate body (P;P') is connected exclusively via spring segments (FS1, FS2) which allow a relative displacement of the respective mounting section (BA2; BA2', BA3') and the respective island section (IA) to each other in an elastically resilient manner, wherein the spring segments (FS1, FS2) surround their assigned mounting point (BP2, BP2', BP3') asymmetrically.;

A method for fixating a bone fragment may include delivering a first device into a first bone such that a first portion of the first device is fixed in the first bone and a second portion of the first device extends outward from the first bone; cutting the first bone to generate the bone fragment, wherein the first portion of the first device is fixed in the bone fragment; and placing an apparatus on an exterior surface of the bone fragment, the apparatus having two or more fixation holes, at least one of which includes a slot. The method may include positioning the second portion through the slot; securing the apparatus onto the exterior surface of the bone fragment by delivering a first fixation device into the bone fragment through a second fixation hole; and removing the first device from the first bone.
