Define osteosynthesis

A general description of suitable agents is included in Appendix 1. The authors retrospectively evaluated the short-term clinical outcomes of 10 patients who underwent elbow HA for distal humerus fractures. If these concentrations and times are exceeded significantly, discoloration or corrosion could occur with some materials.

Postoperative and preoperative start of low molecular weight heparin LMWH does not change the outcome of mortality or risk of reoperation in patients with hip fractures treated with osteosynthesis, according to a recent study.

The plate is fixed proximally to diaphysis by screws that are inserted percutaneously or by minimal incisions Fig. The authors concluded that in this case series of 6 patients with DHA for non-reconstructable distal humerus fractures, favorable mid-term follow-up results were seen; however, complications were also observed.

The crucial steps are represented by the reestablishment of axis, length and rotation of the femur, using Krettek techniques Krettek et al.

This usually happens because the fractured bone is not accurately re-assembled. Open reduction and internal fixation involves open reduction of the fracture site and fixation with titanium plates. The fibular fracture commonly seen in ankle injuries is often fixed with lag screws protected by a neutralization plate.

A buttress plate is used to prevent a collapse in fracture patterns which are unstable under compressive forces. Most used techniques are HA and angle-stable locking compression plate osteosynthesis.

The screw as claimed in claim 5wherein each cutting ridge is offset from a respective radial axis of the shaft, the radial axis being perpendicular to the central axis and intersecting an outermost location of the respective cutting ridge, such offset being in a direction from the radial axis opposite the direction of rotation of the screw during screw insertion.

Surgical intervention generally involves fusion, eliminating the motion of the upper cervical spine.

Treatment of Pediatric Condylar Fractures: A 20-Year Experience

To understand which method reduces mortality and reoperations while also diminishing bleeding complications, researchers used data from the Norwegian Hip Fracture Register NHFR to compare preoperative and postoperative starts of LMWH. Based on the clinical evidence, arthroplasty with a metal radial head is an acceptable alternative in the treatment of an unreconstructible comminuted fracture.

There were no statistically significant differences between patients receiving LMWH postoperatively or preoperatively 7, 30, and days post operation.

This short-term review suggested that distal humerus HA may be an effective treatment for certain distal humerus fractures. The author described a new triceps exposure approach for TEA, the anconeus-triceps lateral flap, which has proved valuable in patients with distal humeral and olecranon fracture malunion, and its preliminary results at a minimum follow-up of 24 months.

They stated that surgeons should remain cautious in performing TEA in young patients who can be expected to use the TEA in a more demanding fashion, placing them at higher risk for mechanical failure.


It is quite likely that this material will become more commonly used in the future. Span Plating or Bridge Plating Tension Band Plates come in different sizes and shapes depending on the size of the bone and its anatomical shape. From the middle of the plate, the distal hole is a simple and proximal hole of combi hole is threaded.

The angle b1 is also defined as the angle between the main axis AP and the straight line E1 connecting the crests of the threads P.

Bone Plates in Orthopedics – Principle, Types and Uses

Patients present with pain, swelling, limited motion, especially forearm rotation. See Appendix 3 for further details. They are usually self-tapping, that is to say that they do not usually require drilling.

Span Plating or Bridge Plating It is a modification of neutralization mode which is applied when there is comminution and one does not want to dissect the fracture area to avoid devitalization of the fragments. Sebastia-Forcada et al noted that there is no consensus on what type of arthroplasty is best for the treatment of complex proximal humeral fractures in elderly patients.

This backward and forwards cyclical movement is likely to result in early fatigue failure of the plate. English-German online dictionary developed to help you share your knowledge with others.

The mission of the American Academy of Foot and Ankle Osteosynthesis (AAFAO) is to provide comprehensive education in the training of podiatric residents in the techniques and skills of skeletal fixation trauma and reconstructive surgery of the foot and ankle.

lines of osteosynthesis in mandibular fractures, lines of natural compression forces that occur at the distal part of the body and the angle of mandible whereas lines of tension or distraction occur at the superior border of the mandible.

Different anatomical locations demand different shapes and sizes of plates. AOTrauma ORPApril 2 SinceAO has devised.

Internal fixation is an operation in orthopedics that involves the surgical implementation of implants for the purpose of repairing a bone, a concept that dates to the mid-nineteenth century and was made applicable for routine treatment in the mid-twentieth century.
