Linked Elbow Arthroplasty: Rationale, Design Concept, and Surgical Technique

Introduction As noted in Chapters 85 and 86 , the concepts underpinning the design and results of total elbow arthroplasty are improving with increased basic knowledge of elbow mechanics, better designs, and greater surgical experience. In this chapter the general principles of established and improved designs are described; the concepts—details for specific designs and techniques—are described here as well as in Chapters 88 and 89 .…

Unlinked and Convertible Arthroplasty: Design, Concept, and Technique

Introduction Total elbow arthroplasty (TEA) is indicated for pain and functional limitations secondary to inflammatory arthritis, osteoarthritis, posttraumatic arthritis, acute distal humeral fractures, distal humeral nonunions, tumors, osteonecrosis, and dysfunctional instability. Currently available prostheses can be subclassified as linked, unlinked, or convertible implants that can be interchanged between an unlinked or a linked design. This chapter will focus on the design considerations, techniques, and results of…

Distal Humeral Hemiarthroplasty

Introduction Distal humeral hemiarthroplasty (DHH), although first described in 1947, has attracted increasing interest over the last few years as a surgical option for a number of distal humeral disorders. As a result of the improved understanding of the anatomy and biomechanics of the elbow and the availability of anatomical prostheses, it has been recognized that DHH may provide advantages over current treatments for complex fractures…

Radiocapitellar Prosthetic Arthroplasty for Isolated Radiocapitellar Arthritis

Introduction In this chapter we will discuss the evaluation and treatment of patients with isolated primary osteoarthritis of the radiocapitellar joint. Arthritis of the elbow compared with other joints is relatively uncommon. Risk factors include, but are not limited to, a genetic predisposition, manual labor, and an articular fracture. Osteoarthritis of the elbow differs from that of other joints, often with preservation of the joint space…

Biomechanics of Joint Reconstruction

Introduction While we have discussed the biomechanics of the elbow in general terms earlier in this book, we now focus on concepts relevant to joint reconstruction, especially prosthetic replacement. As in Chapter 3 , the discussion is arbitrarily divided into the main joint functions: motion (kinematics), stability (constraints), and strength (forces). Motion The elbow is classified as a trochleoginglymoid joint; that is, it has two degrees…

Elbow Arthroplasty: Historical Perspective

Introduction The history of prosthetic replacement properly begins with exoprosthetic replacement. Possibly the first recorded such explant is the so-called Cairo toe dating back to 950 BC. Refinements of exoprosthetic replacement were documented in the 16th century with an articulated upper extremity prosthesis successfully used during battle ( Fig. 85.1 ). The earliest attempts at elbow arthroplasty were resection procedures performed as early as 1780 and…

Elbow Pathology From Metabolic Disease

Introduction Today it is recognized that most of the metabolic diseases that affect joints, such as the crystalline arthropathies, are covered under the topic of seronegative arthropathy (see Chapter 78 ). Other than the crystalline arthropathies, with the possible exception of tumoral calcinosis, no metabolic diseases have a special predilection for or a characteristic presentation at or about the elbow joint. Therefore, information is rather limited…

Neuropathic Arthropathy

Introduction As noted in prior editions of this book, neuropathic arthropathy of the elbow is distinctly unusual and poorly understood. Since the last edition, we could find only five reports that were relevant to this discussion. Although a large number of pathologic causes have been associated with neuropathic arthropathy ( Box 82.1 ), only a few of these affect the upper extremity. Thus, the available literature…

Neoplasms of the Elbow

Introduction and Relevance Most benign and malignant tumors of bone and soft tissue are relatively rare, and their occurrence in the region of the elbow is even more unusual. Although there are no valid statistics on soft tissue tumors, compilation of data from the files of the Mayo Clinic until December 2003 indicates that only 1% or so of bone tumors occur at the elbow (…

Septic Arthritis

Introduction Septic arthritis is an inflammatory joint condition secondary to pathologic joint inoculation with infectious microorganisms. It can be the result of either direct inoculation (penetrating trauma) or more commonly caused by hematogenous seeding of the vascular synovial membrane due to a bacteremic episode. Because there is no limiting basement plate under the vascularized synovium, it is easy for bacteria to enter the joint during bacteremia.…

Hematologic Arthritis

Introduction This chapter reviews the elbow pathology associated with some hematologic conditions. The symptoms and radiographic changes of hematologic arthritis resemble inflammatory conditions such as rheumatoid arthritis. The medical treatment of the underlying process plays an important role in the management of elbow symptoms. Hemophilia and sickle cell disease represent the most common examples of hematologic arthritis. The elbow may also be affected in other conditions…

Seronegative Inflammatory Arthritis

Introduction Seronegative inflammatory arthritis refers to a group of conditions in which clinical evidence of noninfectious, active inflammation ( Box 78.1 ) is noted in the joints, but serum autoantibodies, such as rheumatoid factor (RF) or anticyclic citrullinated peptide (anti-CCP) antibodies, are absent. RFs are autoantibodies and were the first autoantibodies described in rheumatoid arthritis (RA). RF is used as a diagnostic marker for RA but…

Rheumatoid Arthritis

Introduction Rheumatoid arthritis (RA) is an inflammatory disease of unknown etiology that has been known to exist since at least the 1800s, when the first detailed description was reported. Indirect evidence that it may have existed as far back as 7000 to 8000 years ago has been reported. Despite extensive research into its etiology and many theories about its pathogenesis, no uniform idea explains its many…

Primary Osteoarthritis of the Elbow

Introduction Over the years since the first edition of this book, primary degenerative arthritis of the elbow is now both well recognized and readily treated. While the pattern of articular changes of the elbow with aging has been studied, from a practical perspective we consider this a “marginal disease.” That is, a consistent pattern of osteophyte formation forms a rim around the margins of the humeral,…

Posttraumatic Elbow Osteoarthritis

Introduction Trauma to the elbow resulting in damage to the articular cartilage or residual surface in congruencies can alter the load distribution across bearing surfaces and place the joint at risk for development of degenerative changes and early-onset arthritis. Posttraumatic articular injuries may be isolated to specific areas of the elbow, such as the radiocapitellar joint or can encompass the entire joint, resulting in profound functional…

Bursitis

Introduction It would seem that it remains appropriate to introduce this topic with the following statement from Monro from 1788: Ensuring the smooth and frictionless working of the body corporate, usually uncomplaining, inconspicuous, hard-working, and very modest in their requirements, the bursae have been so neglected that, even when one of them misbehaves, this is usually misattributed to some more important structure. Olecranon bursitis is the…

Atypical Pain Presentation in the Elbow

Introduction While preceding chapters of this book have addressed management of various medical and surgical conditions in the elbow, the management of pain has been separated out as its own specific chapter. Congenital, traumatic, and surgical issues may all result in painful processes in the normal and athletic patient population. Pain is defined as a subjective, unpleasant sensory and emotional experience associated with actual or potential…

Nerve Entrapment Syndromes

Introduction The diagnosis of a nerve entrapment lesion arising at the elbow can be relatively straightforward if the history, physical examination, electromyographic (EMG) and imaging studies, when indicated, all confirm the diagnosis and the localization of the lesion. However, when the history and physical examination do not correspond, or the electrophysiologic or imaging studies do not support a specific clinical diagnosis, then problems can arise. Therefore,…

Lateral Collateral Ligament Insufficiency

Introduction The lateral collateral ligament (LCL) complex is one of the main structures implicated in the stability of the elbow joint. Insufficiency of the LCL complex is present in many patients with elbow instability. Several basic science and clinical studies have improved our understanding of the contributions of the LCL complex to elbow stability, the etiology of lateral collateral ligament insufficiency, the value of different clinical…
