Volar Approach to the First Extensor Compartment for Surgical Treatment of DeQuervain Tenosynovitis.

Many surgical techniques have been published in regards to the operative management of DeQuervain tenosynovitis. As it has been classically described, stenosing tenosynovitis of the first extensor tendon compartment is a common tendinopathy along the radial side of the wrist causing pain and swelling in the affected area. When surgery is necessary, decompression of the abductor pollicis longus and extensor pollicis brevis tendons decreases first extensor compartment friction and has been shown to successfully alleviate symptoms. A number of varying techniques have been reported in the literature to achieve adequate decompression and minimize postoperative complications such as sensory nerve injury, incomplete decompression, and tendon subluxation. We describe a novel volar approach to the first extensor compartment, which allows direct visualization of the retinaculum and a midline retinacular release. In addition, the volar approach has an associated decreased risk of iatrogenic nerve injury by passing volar and deep to the more superficial sensory nerves that overly the retinaculum. On the basis of our experience, patients do not experience an increased risk of volar tendon subluxation with this approach.

Complication Rates after Lateral Plate Fixation of Periprosthetic Distal Femur Fractures: A Multicenter Study.

OBJECTIVE: Periprosthetic fractures of the distal femur can be challenging injuries to treat; nonunion rates of up to 22% have been reported. The purpose of this study was to determine the rate of complications and nonunion in a multicenter series, and to identify patient or surgical factors that were associated with nonunion. DESIGN: Retrospective comparative study SETTING: Three Level 1 trauma centers PATIENTS: Fifty-five patients with a periprosthetic distal femur fracture proximal to a total knee arthroplasty. Minimum follow up for inclusion was six months or until union or failure. INTERVENTION: Surgical fixation using a precontoured lateral locking plate MAIN OUTCOME MEASUREMENT: Fracture union was the primary outcome. Patient demographic and injury variables (age, comorbidities, fracture classification and characteristics) and surgical technique factors (mode of plate fixation, plate material, working length, screw density, and proximal screw type) were identified and compared between patients who developed a nonunion and those who did not. Regression analysis was performed to identify independent risk factors for nonunion. RESULTS: The overall rate of nonunion was 18% and the total complication rate was 24%. After additional surgery, 49 of 55 patients went on to heal (89%). There were no statistical differences in patient demographic or injury variables between the union and nonunion groups, and none of the variables studied were independent risk factors for nonunion in the regression analysis. CONCLUSIONS: In this series of 55 patients with periprosthetic distal femur fractures treated with precontoured lateral locking plates, 18% developed nonunion and the overall complication rate was 24%. No patient or surgical variables were identified as risk factors. Future research should seek to identify patients at high risk for complication and nonunion who could benefit from alternative fixation strategies or distal femoral replacement.

Outcomes of severe sepsis and septic shock patients after stratification by initial lactate value.

BACKGROUND: In the setting of severe sepsis and septic shock, mortality increases when lactate levels are ≥ 4 mmol/L. However, the consequences of lower lactate levels in this population are not well understood. The study aimed to determine the in-hospital mortality associated with severe sepsis and septic shock when initial lactate levels are < 4 mmol/L. METHODS: This is a retrospective cohort study of septic patients admitted over a 40-month period. Totally 338 patients were divided into three groups based on initial lactate values. Group 1 had lactate levels < 2 mmol/L; group 2: 2-4 mmol/L; and group 3: ≥ 4 mmol/L. The primary outcome was in-hospital mortality. RESULTS: There were 111 patients in group 1, 96 patients in group 2, and 131 in group 3. The mortality rates were 21.6%, 35.4%, and 51.9% respectively. Univariate analysis revealed the mortality differences to be statistically significant. Multivariate logistic regression demonstrated higher odds of death with higher lactate tier group, however the findings did not reach statistical significance. CONCLUSION: This study found that only assignment to group 3, initial lactic acid level of ≥ 4 mmol/L, was independently associated with increased mortality after correcting for underlying severity of illness and organ dysfunction. However, rising lactate levels in the other two groups were associated with increased severity of illness and were inversely proportional to prognosis.

The Incidence and Outcome Differences in Severe Sepsis with and without Lactic Acidosis.

INTRODUCTION: To compare the incidence, characteristics, and outcomes of lactate expressors and nonexpressors in patients with severe sepsis and septic shock. METHODS: This is a retrospective cohort study of patients with severe sepsis and septic shock who presented over a 40-month period to an academic tertiary care center. Primary outcome of interest was in-hospital mortality. Secondary outcomes were hospital length of stay (LOS), Intensive Care Unit (ICU) LOS, and escalation of care. RESULTS: Three hundred and thirty-eight patients met inclusion criteria and were divided into a lactate expressor group (n = 197; initial lactate ≥2.5 mmol/L) and a nonexpressor group (n = 141; lactate <2.5 mmol/L). The mortality rate was 46.2% for lactate expressors and 24.8% for nonexpressors. There were no significant differences in hospital or ICU LOS. The escalation-of-care rate in the severe sepsis nonexpressor group was more than double that found in the expressor group: 16.5% versus 6.2% (P = 0.040). The two groups had baseline differences: expressor group had a higher median Acute Physiology and Chronic Health Evaluation II (APACHE II) illness severity score, and nonexpressors had an increased prevalence of comorbid conditions. APACHE II score (odds ratio [OR] 1.10 (1.07-1.14), P < 0.001) and being in the expressor group (OR 1.72 [1.03-2.89], P = 0.039) increased the odds of mortality. CONCLUSIONS: In patients with severe sepsis and septic shock, lactate nonexpressors are common. Although the mortality in this cohort is less than its counterparts who present with lactate elevation, it is still significant which warrants vigilance in their care.
