Locked Plating versus Nailing for Proximal Tibia Fractures: A Multicenter RCT.

OBJECTIVES: The main 2 forms of treatment for extraarticular proximal tibial fractures are intramedullary nailing (IMN) and locked lateral plating (LLP). The goal of this multicenter, randomized controlled trial was to determine whether there are significant differences in outcomes between these forms of treatment. DESIGN: Multicenter, randomized controlled trial. SETTING: 16 academic trauma centers. PATIENTS/PARTICIPANTS: 108 patients were enrolled. 99 patients were followed for 12 months. 52 patients were randomized to IMN, and 47 patients were randomized to LLP. INTERVENTION: IMN or lateral locked plating. MAIN OUTCOME MEASUREMENTS: Functional scoring including Short Musculoskeletal Functional Assessment, Bother Index, EQ-5Dindex and EQ-5DVAS. Secondary measures included alignment, operative time, range of motion, union rate, pain, walking ability, ability to manage stairs, need for ambulatory aid and number, and complications. RESULTS: Functional testing demonstrated no difference between the groups, but both groups were still significantly affected 12 months postinjury. Similarly, there was no difference in time of surgery, alignment, nonunion, pain, walking ability, ability to manage stairs, need for ambulatory support, or complications. CONCLUSIONS: Both IMN and LLP provide for similar outcomes after these fractures. Patients continue to improve over the course of the year after injury but remain impaired even 1 year later. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Locked Lateral Plating Versus Retrograde Nailing for Distal Femur Fractures: A Multicenter Randomized Trial.

OBJECTIVES: The 2 main forms of treatment for distal femur fractures are locked lateral plating and retrograde nailing. The goal of this trial was to determine whether there are significant differences in outcomes between these forms of treatment. DESIGN: Multicenter randomized controlled trial. SETTING: Twenty academic trauma centers. PATIENTS/PARTICIPANTS: One hundred sixty patients with distal femur fractures were enrolled. One hundred twenty-six patients were followed 12 months. Patients were randomized to plating in 62 cases and intramedullary nailing in 64 cases. INTERVENTION: Lateral locked plating or retrograde intramedullary nailing. MAIN OUTCOME MEASUREMENTS: Functional scoring including Short Musculoskeletal Functional Assessment, bother index, EQ Health, and EQ Index. Secondary measures included alignment, operative time, range of motion, union rate, walking ability, ability to manage stairs, and number and type of adverse events. RESULTS: Functional testing showed no difference between the groups. Both groups were still significantly affected by their fracture 12 months after injury. There was more coronal plane valgus in the plating group, which approached statistical significance. Range of motion, walking ability, and ability to manage stairs were similar between the groups. Rate and type of adverse events were not statistically different between the groups. CONCLUSIONS: Both lateral locked plating and retrograde intramedullary nailing are reasonable surgical options for these fractures. Patients continue to improve over the course of the year after injury but remain impaired 1 year postoperatively. LEVEL OF EVIDENCE: Therapeutic Level I.

Timing of Flap Coverage With Respect to Definitive Fixation in Open Tibia Fractures.

OBJECTIVES: We conducted a large, U.S wide, observational study of type III tibial fractures, with the hypothesis that delays between definitive fixation and flap coverage might be a substantial modifiable risk factor associated with nosocomial wound infection. DESIGN: A retrospective analysis of a multicenter database of open tibial fractures requiring flap coverage. SETTING: Fourteen level-1 trauma centers across the United States. PATIENTS: Two hundred ninety-six (n = 296) consecutive patients with Gustilo III open tibial fractures requiring flap coverage at 14 trauma centers were retrospectively analyzed from a large orthopaedic trauma registry. We collected demographics and the details of surgical care. We investigated the patient, and treatment factors leading to infection, including the time from various points in care to the time of soft-tissue coverage. INTERVENTION: Delay definitive fixation and flap coverage in tibial type III fractures. MAIN OUTCOME MEASUREMENTS: (1) Results of multivariate regression with time from injury to coverage, debridement to coverage, and definitive fixation to coverage in the model, to determine which delay measurement was most associated with infection. (2) A second multivariate model, including other factors in addition to measures of flap delay, to provide the estimate between delay and infection after adjustment for confounding. RESULTS: Of 296 adults (227 M: 69 F) with open Gustilo type III tibial fractures requiring flap coverage, 96 (32.4%) became infected. In the multivariate regression, the time from definitive fixation to flap coverage was most predictive of subsequent wound infection (odds ratio 1.04, 95% confidence interval 1.01 to 1.08, n = 260, P = 0.02) among the time measurements. Temporary internal fixation was not associated with an increased risk of infection in both univariate (P = 0.59) or multivariate analyses (P = 0.60). Flap failure was associated with the highest odds of infection (odds ratio 6.83, 95% confidence interval 3.26 to 14.27, P < 0.001). CONCLUSION: Orthoplastic teams that are dedicated to severe musculoskeletal trauma, that facilitate coordination of definitive fixation and flap coverage, will reduce the infection rates in Gustilo type III tibial fractures. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Extracorporeal shock wave therapy in the treatment of chronic tendinopathies.

Many clinical trials have evaluated the use of extracorporeal shock wave therapy for treating patients with chronic tendinosis of the supraspinatus, lateral epicondylitis, and plantar fasciitis. Although extracorporeal shock wave therapy has been reported to be effective in some trials, in others it was no more effective than placebo. The multiple variables associated with this therapy, such as the amount of energy delivered, the method of focusing the shock waves, frequency and timing of delivery, and whether or not anesthetics are used, makes comparing clinical trials difficult. Calcific tendinosis of the supraspinatus and plantar fasciitis have been successfully managed with extracorporeal shock wave therapy when nonsurgical management has failed. Results have been mixed in the management of lateral epicondylitis, however, and this therapy has not been effective in managing noncalcific tendinosis of the supraspinatus. Extracorporeal shock wave therapy has consistently been more effective with patient feedback, which enables directing the shock waves to the most painful area (clinical focusing), rather than with anatomic or image-guided focusing, which are used to direct the shock wave to an anatomic landmark or structure.

Optimal arthroplasty for femoral neck fractures: is total hip arthroplasty the answer?

Although there is little doubt that arthroplasty of one form or another is appropriate treatment for many patients with a displaced femoral neck fracture, there is ongoing controversy about the relative merits of different types of arthroplasty among specific groups of patients. In particular, total hip arthroplasty is infrequently recommended because of concerns about the perceived high initial cost, increased risk of dislocation, and the anticipated low functional demands and life expectancy of the typical hip fracture patient. When viewed in this traditional context, the merits of total hip arthroplasty are not believed to outweigh the risks, except in the rare instance of a patient with preexisting symptomatic hip arthritis that sustains a hip fracture.Accumulating evidence suggests that a reevaluation of the role of total hip arthroplasty (THA) in patients with hip fracture is warranted. Recent comparative follow-up studies have documented superior and more durable function in a subset of patients with displaced femoral neck fractures after total hip replacement when compared to hemiarthroplasty or uncomplicated osteosynthesis. Economic analyses have suggested that the long-term cost of treatment favors total hip replacement because of the additional cost of treating failures of internal fixation and hemiarthroplasty in patients who survive 2 years or longer after their initial hip fracture. Finally, recent advances in the design of THA components such as the introduction of improved bearing surfaces allowing the use of larger femoral heads, combined with improved surgical techniques, may be making THA safer and less prone to dislocation and other mechanical complications.The purpose of this paper is to review the recent literature regarding the results of total hip replacement in patients with a displaced fracture of the femoral neck. Total hip replacement may have a larger role in the treatment of displaced femoral neck fractures than it has in the past.
