4.5/5.0 mm Locking Plate Narrow Specification
- Plates available holes are 11, 12, 14, 16, 18, 20 and 22.
- Plate has combi holes and round holes. Combi holes allow fixation with locking screws in the threaded section and cortex screws in the dynamic compression unit section for compression.
- The shaft holes accept 5 mm locking screws in the threaded portion or 4.5 mm cortical screws or 5 mm Locking cancellous screws in the compression portion.
- The symmetrical shape of the plate holes enables compression to be achieved in both directions.
- The hole spacing in the plate is regular. Plate positioning is thus not restricted by the presence of a mid-section. This is of particular advantage in comminuted or segmental fractures.
- 4.5/5.0 mm Locking Plate Narrow allow implant placement to address the individual fracture pattern.
- Limited-contact surface reduces bone-to-plate contact and helps to preserve the periosteal blood supply.
- Choice of different lengths of plate eliminates the need to cut plates.
- Pre-contoured plate to match anatomical shape.
- Available in both Titanium and Stainless steel.
- locking plate increases construct stability, decreases risk of screw back-out and subsequent loss of reduction. It also reduces the need for precise anatomic plate contouring and minimizes the risk of stripped screw holes.
- A complete Instruments Set is available for 4.5/5.0 mm Locking Plate Narrow. General Instruments are available for this plate such as Plate Bending Press, Plate Holding Forceps, Plate Bending Pliers, Bone Holding Forceps, Bone Elevators, Bone Cutter, Bone Nibbler, Depth Gauge, Sleeve, Screw Driver, Trocar Sleeve etc.
4.5/5.0 mm Locking Plate Narrow Uses
4.5/5.0 mm Locking Plate Narrow is intended for fixation of various long bones, such as the humerus, femur and tibia. These are also used in fixation of peri-prosthetic fractures, osteopenic bone and fixation of non unions and malunions in adult patients. The oval shaped hole is designed to create dynamic pressure between the fractured bone fragments.
Advantages of using Locking Plate for 4.5/5.0 mm Locking Plate Narrow
- 4.5/5.0 mm Locking Plate Narrow is a locking plate so it does not have to precisely contact the underlying bone in all areas. When screws are tightened, they “lock” to the threaded screw holes of the plate, stabilizing the segments without pulling the bone to the plate. Locking screws make it impossible for screw insertion to alter the reduction. Non locking plate/screw systems require a precise adaptation of the plate to the underlying bone. Without this close contact, tightening of the screws will pull the bone segments toward the plate, resulting in loss of reduction and possibly the occlusal relationship
- Locking plate/screw systems do not disrupt the underlying cortical bone perfusion as much as conventional plates, which compress the plate to the cortical bone.
- Screws are unlikely to loosen from the plate. Similarly, if a bone graft is screwed to the plate, a locking head screw will not loosen during the phase of graft incorporation and healing. The possible advantage to this property of a locking plate/screw system is decreased risk of inflammatory complications due to hardware loosening.
- Locking plate/screw systems have been shown to provide more stable fixation than conventional non locking plate/screw systems.
Locking Screw Technology
The heads of the locking screws contain male threads while the holes in the plates contain female threads. This allows the screw head to be threaded into the 4.5/5.0 mm Locking Plate Narrow hole, locking the screw into the plate. This technical innovation provides the ability to create a fixed angle construct while using familiar plating techniques.
Locking Plate Technology
By using locking screws in a bone plate, a fixed-angle construct is created. In osteopenic bone or fractures with multiple fragments, secure bone purchase with conventional screws may be compromised. Locking screws do not rely on bone/plate compression to resist patient load, but function similarly to multiple small angled blade plates. In osteopenic bone or comminuted fractures, the ability to lock screws into a fixed-angle construct is imperative.
By combining locking screw holes with compression screw slots in the shaft, the plate can be used as both a locking device and a fracture compression device. If compression is desired, it must be achieved first by inserting the standard screws in the compression screw slots before inserting any locking screws.
4.5/5 mm Locking Plate Narrow Contraindications
Contraindications may be qualified or total, and need to be taken into consideration when evaluating the prognosis in each case. Alternative management techniques may need to be considered under the following conditions:
- Acute or chronic infections, either local or systemic.
- Local or systemic accurate or chronic inflammation.
- Serve muscular, nervous or vascular disease endangering the affected area.
- Defective bone structures, which would impede adequate anchoring of the implant.
- All associated diseases which could endanger the function and success of the implant.
Preoperative Planning for 4.5/5 mm Locking Plate Narrow
The operating planning is carried out following a thorough clinical evaluation of the patient, Also, x-rays must be taken to allow a clear indication of the bony anatomy and associated deformities. At the time of the operation, the corresponding implantation instruments in addition to a complete set of 4.5/5 mm Locking Plate Narrow must be available.
The clinician should discuss with the patient the possible risks and complications associated with the use of Implants. It is important to determine pre-operatively whether the patient is allergic to any of the implant materials. Also, the patient needs to be informed that the performance of the device cannot be guaranteed as complications can affect the life expectancy of the device.
4.5/5 mm Locking Plate Narrow Precautions
- Confirm functionality of instruments and check for wear during reprocessing. Replace worn or damaged instruments prior to use.
- It is recommended to use the instruments identified for this screw.
- Handle devices with care and dispose worn bone cutting instruments in a sharps container.
- Always irrigate and apply suction for removal of debris potentially generated during implantation or removal.
4.5/5 mm Locking Plate Narrow Warnings
- 4.5/5 mm Locking Plate Narrow can break during use (when subjected to excessive forces). While the surgeon must make the final decision on removal of the broken part based on associated risk in doing so, we recommend that whenever possible and practical for the individual patient, the broken part should be removed. Be aware that implants are not as strong as native bone. Implants subjected to substantial loads may fail.
- Instruments, screws and cut plates may have sharp edges or moving joints that may pinch or tear user’s glove or skin.
- Take care to remove all fragments that are not fixated during the surgery.
- While the surgeon must make the final decision on implant removal, we recommend that whenever possible and practical for the individual patient, fixation devices should be removed once their service as an aid to healing is accomplished. Implant removal should be followed by adequate post-operative management to avoid refracture.
4.5/5 mm Locking Plate Narrow General Adverse Events
As with all major surgical procedures, risks, side effects and adverse events can occur. While many possible reactions may occur, some of the most common include: Problems resulting from anesthesia and patient positioning (e.g. nausea, vomiting, dental injuries, neurological impairments, etc.), thrombosis, embolism, infection, nerve and/or tooth root damage or injury of other critical structures including blood vessels, excessive bleeding, damage to soft tissues incl. swelling, abnormal scar formation, functional impairment of the musculoskeletal system, pain, discomfort or abnormal sensation due to the presence of the device, allergy or hypersensitivity reactions, side effects associated with hardware prominence, loosening, bending, or breakage of the device, mal-union, non-union or delayed union which may lead to breakage of the implant, reoperation.
