4.5/5 mm Locking Plate Proximal Femoral Lateral Type-I, Right/Left Uses
4.5/5 mm Locking Plate Proximal Femoral Lateral Type-I, Right/Left is intended for fractures of the femur including:
- Fractures of the trochanteric region, trochanteric simple, trochanterodiaphyseal, multifragmentary pertrochanteric, intertrochanteric reversed or transverse or with additional fracture of the medial cortex.
- Fractures of the proximal end of the femur combined with ipsilateral shaft fractures.
- Metastatic fracture of the proximal femur.
- Osteotomies of the proximal femur.
- Plate also for use in fixation of osteopenic bone and fixation of nonunions or malunions.
Advantages of using Locking Plate Proximal Femoral Lateral Type-I, Right/Left
- 4.5/5 mm Locking Plate Proximal Femoral Lateral Type-I, Right/Left 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 mm Locking Plate Proximal Femoral Lateral Type-I, Right/Left 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 Proximal Femoral Lateral Type-I, Right/Left 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.
Warnings and Precautionary for 4.5/5 mm Locking Plate Proximal Femoral Lateral Type-I, Right/Left
Before using 4.5/5 mm Locking Plate Proximal Femoral Lateral Type-I, Right/Left, the surgeon and ancillary staff should study the safety information in these instructions, as well as any product-specific information in the product description, surgical procedures and/or brochures.

At the time of the operation, the corresponding implantation instruments in addition to a complete set of 4.5/5 mm Locking Plate Proximal Femoral Lateral Type-I, Right/Left 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 Proximal Femoral Lateral Type-I, Right/Left 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.

4.5/5 mm Locking Plate Proximal Femoral Lateral Type-I, Right/Left Warnings
- 4.5/5 mm Locking Plate Proximal Femoral Lateral Type-I, Right/Left 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.
