Treatment of olecranon fractures in older individuals: a cross-sectional survey of surgeon treatment preferences.

Background: With an aging population, the incidence of olecranon fractures in older patients is increasing. The standard of care has traditionally included operative management for displaced fractures. Recent literature has called this standard of care into question. Older patients may be at increased risk of operative complications and may have satisfactory functional outcomes with nonoperative management. Given recently evolving evidence, the current treatment preferences of orthopedic surgeons for older patients with displaced olecranon fractures are unknown. Methods: We administered a cross-sectional survey of Canadian orthopedic surgeons via e-mail invitation and online survey form to determine treatment preferences for patients aged 65-75 and >75 years with simple displaced and comminuted displaced stable olecranon fractures. Respondents reviewed representative images and were asked to indicate their preferred treatment based on patient age. We also asked respondents to indicate their perceived importance of 11 patient factors on treatment decision-making. Results: We received 200 responses (33.8% response rate). For patients aged 65-75 years with simple displaced fractures, surgeons preferred tension-band wiring (n = 110, 56%) to plating (n = 82, 42%, P = .005), while only 3% (n = 5) preferred nonoperative treatment. For patients aged >75 years with simple displaced fractures, surgeons preferred operative (n = 144, 73%) to nonoperative management (n = 51, 26%; P < .01) with either tension-band wiring (n = 77, 39%) or plating (n = 67, 34%). In these patients, early range of motion (n = 35, 18%) was preferred to immobilization (n = 16, 8%; P = .004). For comminuted fractures, plate fixation was preferred for patients aged 65-75 years (n = 189, 95%) and >75 years (n = 131, 68%). In patients aged >75 years, this was followed by early range of motion (n = 35, 18%) and immobilization (n = 24, 13%). Of the 11 factors surveyed, participation in high-intensity activities (mean rank = 9.4), independent living (mean rank = 8.8), and disrupted extensor mechanism (mean rank = 8.3) were ranked most highly for increasing likelihood of surgical treatment. Conclusion: In patients aged 65 to 75 years, operative management is favored by most surgeons, with tension-band wiring preferred over plating for simple displaced fractures. In patients aged >75 years, operative management is again preferred by most respondents for simple and comminuted fractures. Despite operative preferences, there is a paucity of quality evidence to guide treatment decision-making, particularly in patients aged >75 years.

Optimal entry point for antegrade and retrograde femoral intramedullary nails.

Surgical management of femoral shaft fractures with intramedullary nails has become the standard of care, with multiple options for entry point described, including piriformis entry, trochanter entry and retrograde femoral nails. Our present review describes the surgical anatomy of the proximal and distal femur and its relation to different entry points for intramedullary femoral nails. In addition, we reviewed relative indications for each technique, difficulties associated and possible complications.

How Does Orthopaedic Research Affect Patient Care?

Academic medicine hinges on high-quality results from research. Surgeon scientists spend their career acquiring grants, writing papers, and educating a next generation of scientists. The real question is how well are we at playing this game? Does our research change surgical practice or affect patient care or government policy? Ideally, published research does and will continue to shape the way care is delivered. Key questions remain, however; what is the return on research investment in orthopaedics? How can surgeons decide which "evidence" matters, and does practice-change only refer to Level I evidence (randomized trials)? This review considers all these questions.

Understanding and Taking Control of Surgical Learning Curves.

As surgical techniques continue to evolve, surgeons will have to integrate new skills into their practice. A learning curve is associated with the integration of any new procedure; therefore, it is important for surgeons who are incorporating a new technique into their practice to understand what the reported learning curve might mean for them and their patients. A learning curve should not be perceived as negative because it can indicate progress; however, surgeons need to understand how to optimize the learning curve to ensure progress with minimal patient risk. It is essential for surgeons who are implementing new procedures or skills to define potential learning curves, examine how a reported learning curve may relate to an individual surgeon's in-practice learning and performance, and suggest methods in which an individual surgeon can modify his or her specific learning curve in order to optimize surgical outcomes and patient safety. A defined personal learning contract may be a practical method for surgeons to proactively manage their individual learning curve and provide evidence of their efforts to safely improve surgical practice.

Lateral Elbow Exposures: The Extensor Digitorum Communis Split Compared with the Kocher Approach.

INTRODUCTION: In comparison with the frequently used modified Kocher approach, the extensor digitorum communis (EDC) splitting approach allows improved access to the anterior half of the radial head, which is most commonly fractured, while reducing the risk of iatrogenic injury to the lateral collateral ligament. STEP 1 MAKE THE INCISION MODIFIED KOCHER APPROACH: Make an oblique 7-cm lateral incision beginning at the proximal edge of the lateral epicondyle and extending distally over the center of the radial head toward the posterior ulnar border of the extensor carpi ulnaris muscle belly. STEP 2 DEVELOP THE INTERVAL BETWEEN THE ANCONEUS AND THE EXTENSOR CARPI ULNARIS: Identify and develop the intermuscular interval between the anconeus and the extensor carpi ulnaris. STEP 3 PERFORM THE LATERAL ELBOW CAPSULOTOMY: Longitudinally incise the lateral elbow capsule and annular ligament anterior to the lateral ulnar collateral ligament. STEP 4 THE EXTENDED MODIFIED KOCHER APPROACH: Extend the exposure by elevating the common extensor origin (extensor carpi radialis brevis, EDC, and extensor carpi ulnaris) proximally off the lateral epicondyle and reflect it anteriorly. STEP 5 MAKE THE INCISION EDC SPLITTING APPROACH: Make a longitudinal oblique 5 to 6-cm lateral incision beginning at the proximal edge of the lateral epicondyle and extending distally over the radial head toward the Lister tubercle. STEP 6 IDENTIFY AND SPLIT THE EDC: The EDC tendon is identified and bisected longitudinally starting proximally at its origin on the lateral epicondyle and extending 20 mm distally from the radiocapitellar joint. STEP 7 PERFORM THE LATERAL ELBOW CAPSULOTOMY: The annular ligament and joint capsule are then incised collinear with the EDC split anterior to the equator of the capitellum. STEP 8 EXTENDED EDC SPLITTING APPROACH: Extend the exposure by detaching the anterior half of the EDC tendon and the extensor carpi radialis brevis tendon from the lateral epicondyle. STEP 9 LAYERED CLOSURE: Perform an interrupted layered closure. RESULTS: In our recent cadaveric study, we quantitatively compared the modified Kocher and EDC splitting approaches in order to determine which provided the greatest exposure of the anterior aspect of the radial head, which is most commonly fractured.IndicationsContraindicationsPitfalls & Challenges.

Objective analysis of lateral elbow exposure with the extensor digitorum communis split compared with the Kocher interval.

BACKGROUND: The most widely used surgical approach to treat radial head fractures is through the Kocher interval. However, the extensor digitorum communis (EDC) splitting approach is thought to allow easier access to the anterior half of the radial head, which is more commonly fractured. The aim of this cadaveric study was to compare the osseous and articular surface areas visible through the EDC split and the Kocher interval. METHODS: Four approaches were used in fresh frozen cadaveric upper extremities: EDC splitting (n = 6), modified Kocher (n = 6), extended EDC splitting (n = 6), and extended modified Kocher (n = 4). For each approach, the osseous and articular surface areas visualized were outlined with use of a burr. Each elbow was then stripped of soft tissue and a digitized three-dimensional model was created with use of a surface scanning system. The visible surface area obtained with each approach was mapped and quantified with use of the markings created with the burr. RESULTS: The EDC splitting approach provided greater exposure of the anterior half of the radial head (median, 100%) compared with the modified Kocher approach (68%, p < 0.05). The extended modified Kocher and extended EDC splitting approaches provided comparable visualization of the distal aspect of the humerus, capitellum, radial head, and coronoid process. CONCLUSIONS: The results suggest that the EDC splitting approach provides more reliable visualization of the anterior half of the radial head while minimizing soft-tissue dissection and reducing the risk of iatrogenic injury to the lateral ulnar collateral ligament.

The rheumatoid wrist.

Wrist involvement is common in patients with rheumatoid arthritis. Individual patient assessment is important in determining functional deficits and treatment goals. Patients with persistent disease despite aggressive medical management are candidates for surgery. Soft-tissue procedures offer good symptomatic relief and functional improvement in the short term. Extensor and flexor tendons may rupture because of synovial infiltration and bony irritation. When rupture occurs, direct repair usually is not possible. However, when joints that are motored by the ruptured tendon are still functional, tendon transfer or grafting may be considered. Because of the progressive nature of the disease, dislocation and end-stage arthritis often require stabilization with bony procedures. The distal radioulnar joint is usually affected first and is commonly treated with either the Darrach or the Sauvé-Kapandji procedure. Partial wrist fusion offers a compromise between achieving stability of the affected radiocarpal joint and maintaining motion at the midcarpal joint. For pancarpal arthritis, total wrist fusion offers reliable pain relief at the cost of motion. Total wrist arthroplasty is an alternative that preserves motion; however, the outcomes of total wrist replacement are still being evaluated.
