Elbow Plating System Surgical Technique (ELB00-05-M) Elbow Plating System Surgical Technique Acumed® is a global leader of innovative orthopaedic and medical solutions. We are dedicated to developing products, service methods, and approaches that improve patient care. Acumed® Elbow Plating System Designed in conjunction with Shawn W. O’Driscoll, MD, PhD, the Elbow Plating System is engineered to address fractures of the distal humerus, olecranon, and coronoid. The Elbow Plating System includes precontoured, indication-specific plates and a low-profile Olecranon Plate design with anatomic curvature and instrumentation to aid with plate and screw insertion. This system also includes the Hexalobe Screw System with variable angle Tap-Loc® Technology for the Medial and Lateral Distal Humerus Plates. Acumed offers Posterolateral Plates in addition to Medial and Lateral Distal Humerus Plates to provide multiple plating solutions for elbow fracture management. Indications for Use: ⊲ Fractures of the distal humerus, olecranon, and coronoid ⊲ Osteotomies of the olecranon Definition Warning Indicates critical information about a potential serious outcome to the patient or the user.

O’Driscoll, MD, PhD Figure 1 Technical Objectives for Locking Olecranon Plates: ⊲ Each screw should be as long as possible ⊲ Locking screws should interlock to provide a stable “fixed angle” structure inside the bone fragment ⊲ Plate should buttress against anterior pull of elbow flexors ⊲ Plate should provide stable fixation of the ulnar shaft ⊲ Plate should be applied with compression across the fracture ⊲ Plate must be strong and stiff enough to resist bending before union occurs Fracture Reduction and 1 Plate Placement Attach the Olecranon Plate Proximal Targeting Guide (80-0654) to the Olecranon Plate (70-03XX) with the Locking Bolt: M4 (80-0652). Flex the elbow 90 degrees, reduce the fracture, and apply the plate. The prongs in the proximal end of the plate should penetrate the triceps tendon and provide provisional fixation. These prongs are not intended to compress the tendon and a gap between the plate and the bone should be visible on X-ray. Note: Plates designed for use on the left arm are blue. Plates designed for use on the right arm are green. Note: Using the Extended Olecranon Plate (70-03XX) requires splitting the triceps tendon. Figure 2 Provisional Wire Placement 2 If a locking screw is to be utilized in the most proximal hole of the plate, thread the 2.3 mm Locking Drill Guide 6–65 mm (80-0622) into the plate hole. A 2.0 mm x 9" ST K-wire (WS-2009ST) is drilled through the locking drill guide and across the fracture site, penetrating the anterior metaphyseal cortex.

  • Upper Extremity Fractures
    Department of Rehabilitation Services Physical Therapy Standard of Care: Distal Upper Extremity Fractures Case Type / Diagnosis: This standard applies to patients who have sustained upper extremity fractures that require stabilization either surgically or non-surgically. This includes, but is not limited to: Distal Humeral Fracture 812.4 Supracondylar Humeral Fracture 812.41 Elbow Fracture 813.83 Proximal Radius/Ulna Fracture 813.0 Radial Head Fractures 813.05 Olecranon Fracture 813.01 Radial/Ulnar shaft fractures 813.1 Distal Radius Fracture 813.42 Distal Ulna Fracture 813.82 Carpal Fracture 814.01 Metacarpal Fracture 815.0 Phalanx Fractures 816.0 Forearm/Wrist Fractures Radius fractures: • Radial head (may require a prosthesis) • Midshaft radius • Distal radius (most common) Residual deformities following radius fractures include: • Loss of radial tilt (Normal non fracture average is 22-23 degrees of radial tilt.) • Dorsal angulation (normal non fracture average palmar tilt 11-12 degrees.) • Radial shortening • Distal radioulnar (DRUJ) joint involvement • Intra-articular involvement with step-offs. Step-off of as little as 1-2 mm may increase the risk of post-traumatic arthritis. 1 Standard of Care: Distal Upper Extremity Fractures Copyright © 2007 The Brigham and Women's Hospital, Inc. Department of Rehabilitation Services. All rights reserved. Types of distal radius fracture include: • Colle’s (Dinner Fork Deformity) -- Mechanism: fall on an outstretched hand (FOOSH) with radial shortening, dorsal tilt of the distal fragment. The ulnar styloid may or may not be fractured. • Smith’s (Garden Spade Deformity) -- Mechanism: fall backward on a supinated, dorsiflexed wrist, the distal fragment displaces volarly. • Barton’s -- Mechanism: direct blow to the carpus or wrist.

To our best knowledge, few studies have evaluated the use of the olecranon bone graft as a treatment for non-union after distal finger replantation. Our aim in this report was to present our experience of using olecranon grafts in our nonunion patients undergoing distal replantations.
