Pedicle Screws

Pedicle screws are orthopedic implants used occasionally in a spinal fusion to add extra support and strength to the fusion while it heals. Pedicle screws are placed above and below the vertebrae that were fused. A rod is used to connect the screws which prevents movement and allows the bone graft to heal.

Compression Screws

These screws include a patented taper, variable thread pitch, and fully threaded length to provide strong compression and holding power for fractures, osteotomies, and fusions. 

Locking/Non-Locking Screws

The locking plate has a corresponding threaded plate hole. During insertion, the locking head screw engages and locks into the threaded plate hole. Friction between plate and bone is necessary for stability using conventional screws.

Cervical Plates

The surgeon inserts a spacer and permanently fixes the adjacent vertebrae to one another with a cervical plate. This stabilization eliminates movement and often relieves your pain and other symptoms. However, it reduces your flexibility and range of motion.

Interbody Fusion Devices

Interbody fusion cages are small hollow medical implants that are inserted into the intervertebral space to restore physiological disc height and to allow bony fusion. 

PEEK Cages

Polyetheretherketone (PEEK) cages have been widely used during the past decade in implantable medical devices for patients with degenerative disorders of the cervical spine. The use of a cervical PEEK cage is beneficial in that it does not require bone grafting.

Limb Lengthening Rods

Limb lengthening is a reconstructive procedure where the deformed bone is straightened or missing bone is replaced. It is performed in children and adults who have variations in their leg length as a result of diseases, injuries or birth defects. The process of increasing the bone length depends on tissue and bone regeneration. When the bone is pulled apart, it tends to regenerate at the rate of approximately 1mm per day. There are two phases of lengthening until the bone is healed: distraction phase and consolidation phase. The distraction phase involves lengthening of the bone. Consolidation phase involves hardening and calcification of this new bone which is still weak due to lack of calcium. Implants can be external or intramedullary.

Extremity Fixation Plates

Internal fixation allows shorter hospital stays, enables patients to return to function earlier, and reduces the incidence of nonunion (improper healing) and malunion (healing in improper position) of broken bones. The implants used for internal fixation are made from stainless steel and titanium, which are durable and strong. If a joint is to be replaced, rather than fixed, these implants can also be made of cobalt and chrome. These orthopedic implants are compatible with the body and rarely cause an allergic reaction.

Suture Anchors

Suture Anchors are very useful implantable medical devices for fixing tendons and ligaments to bone. They are made up of the Anchor – which is inserted into the bone, and the Eyelet – which is a hole or a loop in the anchor to through which the suture passes. The anchor may be a screw mechanism or an interference fit. The eyelet links the anchor to the suture.

Straight and Bent Rods

Titanium or cobalt chrome implants used in spinal fusion surgery (or scoliosis surgery), they run parallel to the spine on both sides held in place by pedicle screws with a locking cap or screw.

Fibula Plates

Fibula plates are generally forged in stainless steel or titanium. The plates feature an anatomic shape and profile, both distally and along the fibular shaft. The combi-holes in the LCP plate shaft combine a dynamic compression unit (DCU) hole with a locking screw hole. Combi-holes provide maximum flexibility with the options of axial compression and locking capability throughout the length of the plate shaft.

Compression Plates

Compression plates are designed to apply compression to fractures. The standard compression plate is usually referred to as a dynamic compression plate, which is a misnomer since these plates supply static compression to a fracture. Static compression enables quicker healing times and less pain during recovery.

MTP Plates

MTP plates include compression, revision, and lower profile “wingless” plates that can provide lower extremity surgeons with a variety of options to treat metatarsophalangeal joint fractures, fusions, and osteotomies. With a low-profile design that can help minimize soft tissue irritation, MTP plates are designed to be incredibly strong, enabling solid fusions of metatarsophalangeal joints.

Trial Spacers & Instrumentation

MDI will make trial spacers and instrumentation to compliment the range of orthopedic implants we manufacture for our customers. These are often made from stainless steel and require heat treatment, chrome/hard coating and enamel color banding to designate sizes.
