Using an Institute Model to Reduce the Incidence of Venous Thromboembolism Within a Large Hospital System.

Internal benchmarking showed that the Orthopedic Institute had an above average rate of venous thromboembolism (VTE) along with other institutes. The Orthopedic VTE Quality Team was assigned to investigate opportunities for improvement to share with other institutes. To investigate the issues and barriers to the administration of chemical and mechanical VTE prophylaxis, data collection included real-time point prevalence study, physician and nursing surveys, and electronic medical record audits. The results of the data collection indicated inconsistencies in nursing and patient care. Therefore a VTE policy and VTE educational poster was developed. In conjunction, nursing education will be completed to describe the best practice for sequential compression devices and anticoagulant therapies and documentation. The physician will be notified for refusals on either mechanical or chemical prophylaxis.

Knotless Suture Anchor Suspensionplasty for Basal Joint Arthritis A Prospective Case Series with Short-Term Outcomes.

BACKGROUND: The mainstay of surgical treatment for advanced basal joint arthritis is arthroplasty. Many differ- ent techniques of basal joint arthroplasty exist, but none has been determined to be superior to the others, and most methods used to maintain the post-trapeziectomy space require postoperative immobilization or pin fixation. In this article, we describe a knotless suture anchor suspen- sionplasty (KSAS) technique and present a prospective case series with short-term outcomes. The KSAS technique utilizes a suspension construct to maintain the post-trapeziectomy space, allowing for early mobilization without the need for pin fixation or casting. METHODS: Twenty-five patients underwent trapeziectomy with KSAS. Visual analog scale (VAS) for pain scores and Quick Disabilities of the Arm, Shoulder, and Hand (qDASH) scores were recorded preoperatively and at multiple post- operative points. Grip and pinch strengths were recorded. Maintenance of the post-trapeziectomy space and subsidence were determined by comparing preoperative and postopera- tive radiographs. RESULTS: VAS pain scores were significantly reduced from baseline at all postoperative time points with a reduction from 6.54 to 1.47 at 20 to 24 weeks (p < 0.001). qDASH scores were also significantly decreased from baseline at all time points except for 1 week postoperatively with a re- duction from 57.71 to 12.27 at 20 to 24 weeks (p < 0.001). Grip strength improved from 80.43% compared to the non- operative side preoperatively to 90.36% at 6 months status post KSAS (p < 0.05). Radiographically, subsidence was 35.11% at final follow-up. CONCLUSIONS: Our data suggest that KSAS is a safe, effective, and reproducible basal joint arthroplasty tech- nique that allows for early mobilization while sufficiently maintaining the post-trapeziectomy space enough to prevent impingement of the first metacarpal on the scaphoid. Al- though there are limitations to this prospective case series, the data presented here warrant long-term outcome studies utilizing this technique.

The Loop 'n' Tack Knot: Biomechanical Analysis of a Novel Suture Technique for Proximal Biceps Tenodesis.

BACKGROUND: Secure tendon grasping is critical to the success of any tenodesis procedure. Several techniques currently used for tendon grasping can result in longitudinal splitting of the tendon, causing construct failure and failure of the tenodesis. PURPOSE: To compare the Loop 'n' Tack knot as a tendon-grasping technique with other common suture techniques. We investigated the biomechanical strength and mode of failure. STUDY DESIGN: Controlled laboratory study. METHODS: Eleven matched pairs of proximal biceps were harvested from fresh-frozen cadaveric shoulders. One tendon from each pair was stitched using 1 of 4 different techniques. The suture techniques evaluated included the Loop 'n' Tack with 2 different types of high-strength nonabsorbable suture, a double half-racking stitch, and a Krakow stitch. Samples were cyclically loaded between 5 and 20 N for 100 cycles, followed by a pull to failure at 33 mm/s. RESULTS: The Loop 'n' Tack techniques were equivalent to the double half-racking and Krakow techniques for load to ultimate failure (P = .817 and P = .984, respectively). The double half-racking technique was the stiffest construct, which was significantly greater than the second-stiffest group, the Loop 'n' Tack method with both FiberLink suture (P = .012) and SutureTape (P = .002), which had greater stiffness than the Krakow group (P < .001). The most common failure mode for the Loop 'n' Tack stitch was suture breakage compared with the Krakow and double half-racking methods, where the most common mode of failure was suture pullout from the tendon (P < .001). CONCLUSION: Biomechanical testing found that the Loop 'n' Tack techniques had similar ultimate load to failure values when compared with the double half-racking and Krakow methods. Mode-of-failure analysis showed that the Loop 'n' Tack construct typically failed by suture breakage, whereas the other techniques failed by suture pullout. CLINICAL RELEVANCE: The Loop 'n' Tack technique allows for secure grasping of tissue without the need for externalization of the tendon. This technique may be beneficial in compromised or poor-quality tissue without reducing overall pullout strength when compared with a standard half-racking or Krakow stitch.

Epidemiological Analysis of Displaced Supracondylar Fractures.

INTRODUCTION:  Supracondylar fractures are one of the most common fracture patterns sustained by children, and one of the most common injuries requiring operative fixation. Understanding the complications associated with supracondylar fractures is vital for the practicing orthopedic surgeon. This analysis of supracondylar fractures examined the clinically important aspects including vascular injury, compartment syndrome, neurological injury, brachialis entrapment, associated injuries, and etiologies of injury. Recent advances in technology have resulted in a myriad of new forms of recreational equipment for children to play with. The purpose of this study is to compare the historical literature, the current literature, and a single surgeon's sample of supracondylar fractures. In addition, this study aims to evaluate if any changes in epidemiology or etiology have occurred due to the development of new recreational equipment. OBJECTIVE:  The purpose of this study is to evaluate and provide a qualitative overview of the epidemiology of displaced supracondylar fractures, to compare historically reported numbers to more recent literature as well as a single surgeon sample, and to evaluate if changes in epidemiology or etiology have occurred due to the new recreational equipment that children use. METHODS: Some 75 displaced supracondylar elbow fractures were reviewed. Data elements recorded from the electronic medical record (EMR) included patient age, gender, height, weight, handedness, date, time, location, mechanism, Gartland classification, concurrent injuries, and neurovascular status.  Results: In this study, there were 42 males and 33 females. The average age was six years. Some 70 of the 75 patients were older than the age three. One fracture was open, nine fractures had a pucker sign, seven presented with a nerve palsy, four presented without a pulse, and seven patients presented with an additional ipsilateral distal radius fracture. All fractures were the result of a fall. Falls from playground equipment resulted in 29 fractures. There were 10 from falls off of furniture, six from falls during sports, three from falls on the stairs, and three from fall off of bikes. The remaining fractures resulted from running, tripping, falling from a toy ball, sled, tree, wagon, fence, bounce house, van, deck, power wheels car, ATV, and a go-cart. Some 64 fractures were transferred from 27 different outside hospitals. Eleven fractures presented directly to the ED. Twenty-six fractures occurred during the summer, 20 occurred in the autumn, 6 occurred in the winter, and 23 occurred during the spring. Some 35 fractures occurred at home, 30 on the school grounds, four in a gymnasium, four in a park, one at a farm show, and one in a parking lot. Some 25 fractures were treated between midnight and 8 am, 16 were treated between 8 am and 5 pm, and 34 were treated between 5 pm and midnight.  Conclusion: Pediatric supracondylar fractures are common in children, and many of them require operative intervention. This study examined the most important aspects of supracondylar fractures. This update provides a look at the clinically important aspects of supracondylar fractures and compares them to previous teachings and canon. Despite the advancement and changes in recreational equipment that children are using, children are still sustaining supracondylar fractures in the most common ways including falls from playground equipment and falls from standing.

The Loop 'N' Tack Biceps Tenodesis: An All-Arthroscopic, Intra-Articular Technique.

Tenodesis and tenotomy of the long head of the biceps are treatment options for a wide range of pathologies without clear superior technique or site of fixation. Clinical outcomes comparing numerous techniques for tenotomy versus tenodesis have resulted in similar pain relief; however, tenotomy may result in a cosmetic "Popeye" deformity and fatigue pain. We present a quick, simple, and knotless technique for tenodesis of the long head of the biceps at the proximal aspect of the bicipital grove that can be completed entirely arthroscopically. This technique uses suture to secure a tenotomized proximal biceps tendon to a knotless anchor just proximal to the subscapularis tendon at the proximal biceps groove. The tensionless repair allows the biceps to scar within the biceps groove, thereby reducing subsidence and formation of a "Popeye" deformity and fatigue pain in the biceps seen with tenotomy alone while eliminating the ability to overtension.

Sarcopenia and sarcopenic obesity in patients with complex abdominal wall hernias.

BACKGROUND: Chronic muscle wasting, or sarcopenia, has been associated with poor-health outcomes after major surgical procedures. Here, we explore the utility of CT-generated determinations of sarcopenia as markers of risk in patients undergoing evaluation for complex ventral hernia repair. METHODS: In 148 successive patients being evaluated for complex ventral hernia repair, CT scans were analyzed retrospectively for attributes of the hernia and indices of core-muscle mass, correlating them with preoperative clinical/laboratory profiles and outcomes in 82 patients who had undergone surgery. RESULTS: Prevalence of sarcopenia, and sarcopenia corrected for obesity, was 26% and 20% respectively. Sarcopenia was associated with age, some laboratory indicators, and increased hospital length of stay but not with a higher likelihood of surgical site occurrence. CONCLUSIONS: Obesity may obscure the value of sarcopenia as a marker of metabolic disturbance and postoperative outcome. Image-based measurements of core-muscle mass should be used with caution as predictors of risk in similar surgical populations.

Measuring Surgical Site Infections in Children: Comparing Clinical, Electronic, and Administrative Data.

BACKGROUND: Surgical site infections (SSIs) are an important end point and measure of quality of care. Surgical site infections can be identified using clinical registries, electronic surveillance, and administrative claims data. This study compared measurements of SSIs using these 3 different methods and estimated their implication for health care costs. STUDY DESIGN: Data were obtained from 5,476 surgical patients treated at a single academic children's hospital (January 1, 2010 through August 31, 2014). Surgical site infections within 30 days were identified using a clinical registry in the NSQIP Pediatric, an electronic surveillance method (Nosocomial Infection Marker; MedMined), and billing claims. Infection rates, diagnostic characteristics, and attributable costs were estimated for each of the 3 measures of SSI. RESULTS: Surgical site infections were observed in 2.24% of patients per NSQIP Pediatric definitions, 0.99% of patients per the Nosocomial Infection Marker, and 2.34% per billing claims definitions. Using NSQIP Pediatric as the clinical reference, Nosocomial Infection Marker had a sensitivity of 31.7% and positive predictive value of 72.2%, and billing claims had a sensitivity of 48.0% and positive predictive value of 46.1% for detection of an SSI. Nosocomial Infection Marker and billing claims overestimated the costs of SSIs by 108% and 41%, respectively. CONCLUSIONS: There is poor correlation among SSIs measured using electronic surveillance, administrative claims, and clinically derived measures of SSI in the pediatric surgical population. Although these measures might be more convenient, clinically derived data, such as NSQIP Pediatric, may provide a more appropriate quality metric to estimate the postoperative burden of SSIs in children.

Prevalence of systemic inflammation and micronutrient imbalance in patients with complex abdominal hernias.

OBJECTIVE: To determine the prevalence of low-grade inflammation, micronutrient imbalances and associated clinical profiles in patients being evaluated for complex abdominal hernia repair. METHODS: Review of 127 consecutive adult patients for evaluation of complex ventral hernias from January 2012 to March 2013. Records were analyzed to determine the prevalence and correlations of clinical risk factors, attributes of hernias identified by computerized tomography, and laboratory indices of metabolism, inflammation and micronutrient imbalances. RESULTS: Strong correlations (p < 0.001) were established for body mass index (BMI) with volume of hernia content and C-reactive protein (CRP) level. CRP levels correlated strongly with red cell distribution width and inversely with zinc (p < 0.01). Evidence of micronutrient imbalance (abnormal zinc or red cell distribution width [RDW]) was observed in 48%. CONCLUSIONS: In this comorbidity-rich population with known variability in surgical outcomes, the prevalence of chronic inflammation and micronutrient deficiency are high enough to warrant systemic preoperative evaluation given their possible effect on wound healing and convalescence. Simple repletion is unlikely to improve outcomes without attention to the biological stresses that are associated with micronutrient imbalance.
