RESUMEN
Objectives: To investigate the incidence and severity of knee pain following retrograde intramedullary nailing of femur fractures and to better understand functional outcomes using validated patient-reported outcome measures. Methods: Fifty-three patients with OTA 32 or 33 fractures treated by retrograde nail at a single academic Level 1 trauma center between 2009 and 2020 were retrospectively reviewed. Patients verbally completed the Oxford Knee Score (OKS) and Patient-Reported Outcome Measurement Information System (PROMIS) Short Form 6b, minimum one year postoperatively. Results: Thirty-four (64%) patients reported the presence of pain. Of those reporting pain, 16 (47.1%) reported their pain as mild. Compared to those without pain, patients with knee pain had lower OKS (30.38 +/- 10.65, versus 41.95 +/- 6.87; P <0.001) and higher PROMIS scores (14.65 +/- 6.76 versus 10.95 +/- 7.09; P=0.066). Conclusion: The increasing severity of pain was inversely correlated with functional status as measured by patient-reported measures. At present, the reliability, high union rates, and otherwise low complication rates associated with retrograde femoral nailing justify its continued use. However, knee pain and functional outcomes should remain an integral part of the preoperative discussion with the patient.
RESUMEN
Background: Implant removal due to infection is one of the major causes failure following open reduction and internal fixation (ORIF). The aim of this study was to determine trends and predictors of infection-related implant removal following ORIF of extremities using a nationally representative database. Methods: Nationwide Inpatient Sample data from 2006 to 2017 was used to identify cases of ORIF following upper and lower extremity fractures, as well as cases that underwent infection-related implant removal following ORIF. Multivariate analysis was performed to identify independent predictors of infection-related implant removal, controlling for patient demographics and comorbidities, hospital characteristics, site of fracture, and year. Results: For all ORIF procedures, the highest rate of implant removal due to infection was the phalanges/hand (5.61%), phalanges/foot (5.08%), and the radius/ulna (4.85%). Implant removal rates due to infection decreased in all fractures except radial/ulnar fractures. Tarsal/metatarsal fractures (odds ratio (OR)=1.45, 95% confidence interval (CI): 1.02-2.05), and tibial fractures (OR=1.82, 95% CI: 1.45-2.28) were identified as independent predictors of infection-related implant removal. Male gender (OR=1.67, 95% CI: 1.49-1.87), Obesity (OR=1.85, 95% CI: 1.34-2.54), diabetes mellitus with chronic complications (OR=1.69, 95% CI: 1.13-2.54, P<0.05), deficiency anemia (OR=1.59, 95% CI: 1.14-2.22) were patient factors that were associated with increased infection-related removals. Removal of implant due to infection had a higher total charge associated with the episode of care (mean: $166,041) than non-infection related implant removal (mean: $133,110). Conclusion: Implant removal rates due to infection decreased in all fractures except radial/ulnar fractures. Diabetes, liver disease, and rheumatoid arthritis were important predictors of infection-related implant removal. The study identified some risk factors for implant related infection following ORIF, such as diabetes, obesity, and anemia, that should be studied further to implement strategies to reduce rate of infection following ORIF.
RESUMEN
CASE: A 73-year-old man with a medical history significant for renal cell carcinoma (RCC) presented with widespread osseous metastases and imaging suspicious for RCC metastasizing to a lipoma interdigitated within the right vastus lateralis. The patient's pathological fractures were surgically addressed, and the lipoma excised. Final histology revealed a thigh lipoma involved by metastatic RCC without direct extension. CONCLUSION: Tumor-to-tumor metastasis is a rare occurrence, with RCC typically being the most common "recipient" tumor. This is the first case to the best of our knowledge of RCC metastasizing to a lipoma, highlighting a rare phenomena in a patient with metastatic disease.

Arthroscopic reduction of tibial plateau fractures have been gaining in popularity. Advantages include accurate diagnosis and treatment of joint pathology, minimally invasive soft tissue dissection, quicker recovery of joint motion, and anatomic reduction of joint surface. Success depends on accurate fracture selection. With arthroscopic-assisted reduction of tibial plateau fractures, patient set-up is similar to standard knee arthroscopy, but the C-arm is used to aid with fracture reduction and fixation. Outcomes are comparable or even improved when compared with standard procedures, and morbidity with arthroscopic reduction can often be lower with decreased rates of infection, wound complications, and thromboembolism.

OBJECTIVES: This study aimed to describe the safety and short-term efficacy of the Covered Cheatham-Platinum stent (CCPS) in treating or preventing aortic wall injury (AWI) in patients with coarctation of the aorta (CoA). BACKGROUND: The COAST II trial (Covered Cheatham-Platinum Stents for Prevention or Treatment of Aortic Wall Injury Associated with Coarctation of the Aorta Trial) is a multicenter, single-arm trial using the CCPS for the treatment and/or prevention of AWI in patients with CoA and pre-existing AWI or increased risk of AWI. METHODS: Patients were enrolled if they had a history of CoA with pre-existing AWI (Treatment group) or with increased risk of AWI (Prevention group). Pre/post-implant hemodynamics and angiography were reported. A core laboratory performed standardized review of all angiograms. One-month follow-up was reported. RESULTS: A total of 158 patients (male = 65%; median age 19 years) underwent placement of CCPS. Eighty-three patients had pre-existing AWI. The average ascending-to-descending aorta systolic gradient improved from 27 ± 20 mm Hg to 4 ± 6 mm Hg. Complete coverage of pre-existing AWI was achieved in 66 of 71 patients (93%) with AWI who received a single CCPS. Ultimately, complete coverage of AWI was achieved in 76 of 83 patients (92%); 7 patients had minor endoleaks that did not require repeat intervention. Four patients experienced important access site vascular injury. There were no acute AWI, repeat interventions, or deaths. CONCLUSIONS: The CCPS can effectively treat and potentially prevent AWI associated with CoA. Access site arterial injury is the most common important complication. Longer-term follow-up is necessary to define mid- and late-term outcomes.

OBJECTIVES: The coarctation of the aorta stent trial (COAST) is a pivotal trial of the NuMED Cheatham Platinum Stent(®) for treatment of coarctation of the aorta (CoA). BACKGROUND: CoA is a congenital obstruction to flow through the aorta. Stents have been used since the 1990s to treat CoA; none have been approved by the Food and Drug Administration for this indication. METHODS: In a prospective, multicenter study 105 patients received stents for treatment of CoA. Data was collected in the catheterization laboratory, on discharge and at 1-month postprocedure. RESULTS: Of 105 patients, 69% were male; 57% had native CoA. Noninvasive, baseline systolic blood pressure (SBP) showed upper extremity (UE) SBP to be 140 ± 16 mm Hg and UE to lower extremity (LE) SBP difference 29 ± 17 mm Hg. At catheterization, baseline ratio of minimum CoA diameter to diameter of descending aorta (CoA:DAo) was 0.46 ± 0.16. Implants (104/105) were successful with one stent migration. There were no deaths or serious complications. Paradoxical hypertension occurred in 6%. Four percent of patients experienced somewhat serious adverse events related to the procedure. All patients achieved relief of ascending aorta to Dao pressure gradient: mean = 2.0 ± 4.0 mm Hg (P < 0.001). The CoA:DAo increased to 0.84 ± 0.18. At 1-month, UE SBP was 120 ± 12 mm Hg, UE to LE SBP difference = -1 ± 12 mm Hg. Ninety-nine percent of patients had UE to LE SBP difference <20 mm Hg. CONCLUSIONS: Stenting of CoA, using the NuMED Cheatham Platinum Stent, is acutely safe and effective for treatment of CoA.

BACKGROUND AND METHODS: As the first multicenter quality improvement collaborative in pediatric cardiology, the Joint Council on Congenital Heart Disease National Pediatric Cardiology Quality Improvement Collaborative registry collects information on the clinical care and outcomes of infants discharged home after first-stage palliation of single-ventricle heart disease, the Norwood operation, and variants. We sought to describe the preoperative and intraoperative characteristics of the first 100 patients enrolled in the National Pediatric Cardiology Quality Improvement Collaborative registry. RESULTS: From 21 contributing centers, 59% of infants were male, with median birth weight of 3.1 kg (1.9-5.0 kg); the majority had hypoplastic left heart syndrome (71%). A prenatal diagnosis of congenital heart disease was made in 75%; only one had fetal cardiac intervention. Chromosomal anomalies were present in 8%, and major noncardiac organ system anomalies were present in 9%. Preoperative risk factors were common (55%) but less frequent in those with prenatal cardiac diagnosis (P= .001). Four patients underwent a preoperative transcatheter intervention. Substantial variation across participating sites was demonstrated for choice of initial palliation for the 93 patients requiring a full first-stage approach, with 50% of sites performing stage I with right ventricle to pulmonary artery conduit as the preferred operation; 89% of hybrid procedures were performed at a single center. Significant intraoperative variation by site was noted for the 83 patients who underwent traditional surgical stage I palliation, particularly with use of regional perfusion and depth of hypothermia. CONCLUSIONS: In summary, there is substantial variation across surgical centers in the successful initial palliation of infants with single-ventricle heart disease, particularly with regard to choice of palliation strategy, and intraoperative techniques including use of regional perfusion and depth of hypothermia. Further exploration of the relationship of such variables to subsequent outcomes after hospital discharge may help reduce variability and improve long-term outcomes.
