RESUMO
Sweet syndrome, or acute febrile neutrophilic dermatosis, is a systemic disease process mainly characterized by hyperpyrexia and skin lesions. A newly described entity, necrotizing Sweet syndrome, is a severe and locally aggressive dermatological condition that clinically and histopathologically resembles a necrotizing soft tissue infection. It is characterized by pathergy, a nonspecific inflammatory response to cutaneous trauma resulting in a propagation of the disease. In contrast to a necrotizing infection, this condition responds to systemic steroids. A high clinical suspicion is required in order to distinguish a necrotizing polymicrobial infection from noninfectious necrotizing Sweet syndrome. We present a case following elective hand surgery.

Background: Conversion total hip arthroplasty (cTHA) is increasingly utilized as a salvage procedure for complications associated with fracture fixation around the hip and acetabulum and for failed hip preservation surgery. While primary THA (pTHA) has a high success rate, little is known about outcomes following conversion THA. The purpose of this study is to evaluate patient reported outcomes (PROs) and complication rates following conversion THA compared to primary THA. Methods: Patients that underwent cTHA or pTHA from 2015-2020 at a large tertiary referral academic center were retrospectively identified. THA patients were propensity matched in a 1:1 fashion by age, body mass index (BMI), and sex. Pain scores and PROMIS physical function (PF), pain interference (PI), and depression (DA) scores were compared at preoperative and final postoperative follow up timepoints using independent t-tests. Differences in complication and reoperation rates between cohorts were assessed using chi square analysis. Results: A total of 118 THAs (59 cTHA, 59 pTHA) were included in this analysis with an average follow up of 21.3 months. cTHAs were most commonly performed following hip fracture fixation (50.8%). The conversion cohort had significantly longer lengths of stay (3.6 days vs 1.9 days, p<0.01) and greater use of revision-type implants (39.0% vs 0.0%, p<0.01) compared to pTHA. There was no significant difference in complication rates (cTHA = 15.3%, pTHA = 8.5%; p=0.26), with intraoperative fracture being the most common for both. Primary and conversion THA groups also experienced similar reoperation rates (cTHA = 5.1%, pTHA = 6.8%; p=0.70). No significant differences in PROs at final follow up were identified between groups. Conclusion: Patients undergoing cTHA required increased utilization of revision hip implants and had longer lengths of stay, but had comparable complication and reoperation rates, and ultimately demonstrated similar improvements in PROMIS scores compared to a matched cohort of pTHA patients. Level of Evidence: III.

Periprosthetic distal femoral fracture after total knee arthroplasty carries substantial morbidity and mortality regardless of fixation technique. Surgical treatment is favored in most patients compared with conservative therapy because of high rates of nonunion, malunion, and reoperation after casting or bracing. Internal fixation techniques including retrograde intramedullary nailing and locked plating are favored for surgical treatment in most fractures when bone stock in the distal fragment allows for appropriate fixation. In the setting of deficient distal femoral bone stock or femoral component loosening, revision arthroplasty with distal femoral replacement is the favored technique. Further studies with regard to the use of intramedullary nailing, locked plating, and distal femoral replacement are necessary to refine the indications for each technique and to define the use of combinations of these fixation techniques.

Projections indicate an increase in primary and revision total joint arthroplasties (TJAs). Periprosthetic joint infections (PJIs) are one of the most common and devastating causes of failure after TJA. Perioperative administration of systemic and/or local antibiotics is used for both prophylaxis and treatment of PJI. Antibiotic stewardship is a term that has been met with clinical acceptance and success in other specialties of medicine. Identifying antibiotic best practice use in the fight against PJI is limited by studies that are extremely heterogeneous in their design. Variations in studies include antibiotic selection and duration, surgical débridement steps, type of antibiotic delivery (intra-articular, local, intravenous, and prolonged oral), mix of primary and revision surgery cohorts, both hip and knee cohorts, infecting organisms, and definitions of treatment success/failure. This review highlights the current challenges of antibiotic stewardship in TJA.

Rotator cuff tears with anterior cable disruption show a more detrimental natural history than tears with an intact cable. Anterior cable reconstruction in the setting of such tears provides a potential avenue to improve tissue quality of the repaired construct and enhance repair longevity. Cadaveric studies investigating anterior cable reconstruction have shown biomechanical advantages. We present an arthroscopic surgical technique for rotator cuff anterior cable reconstruction using long head of the biceps tendon autograft in the setting of repairable large-to-massive rotator cuff tears with poor anterior cable tissue quality.
RESUMO
CASE: A 78-year-old woman who underwent reverse total shoulder arthroplasty (RTSA) for proximal humerus fracture developed a Type-3 acromial stress fracture, resulting in increased pain and decreased function 9 months post-op. She was managed nonoperatively with adjunctive teriparatide (FORTEO), and after a 4-month course, she had regained excellent motion and achieved union. CONCLUSION: Teriparatide is a viable adjunct in treating patients nonoperatively with acromial stress fractures after RTSA.

Abuse of opiate medications has reached epidemic proportions, and elective total hip arthroplasty (THA) and total knee arthroplasty (TKA) typically require outpatient use of narcotic medications. This survey sought to determine opiate-prescribing habits of members of the American Association of Hip and Knee Surgeons (AAHKS) for patients undergoing primary THA and TKA. An 11-question online survey was developed to evaluate current prescribing habits for opiate and nonopiate medications prescribed after primary THA and TKA. An invitation to complete the survey was e-mailed to 2698 orthopedic surgeons using an AAHKS listserv. Surgeons' demographic information and their prescribing habits of opiate and nonopiate medications postdischarge were recorded. Data were examined using descriptive statistics, chi-square, and multivariate logistic regression. Responses were received from 325 of 2698 (12.1%) AAHKS members. Significant variation in the type of opiate prescribed and the number of pills dispensed was observed. Higher surgical volume and less years in surgical practice were associated with a higher number of opiate pills prescribed after THA and TKA. There were no statistically significant associations between opiates prescribed and use of an ambulatory surgery center or presence of departmental guidelines. Although THA and TKA are relatively standardized procedures performed nationwide, significant variability exists among surgeons regarding postdischarge opiate- and nonopiate-prescribing habits. There is a need for greater standardization to create a unified, evidence-based, and safe regimen for the postoperative period while reducing the opiate burden in the surrounding community.

PURPOSE: Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are among the most common orthopaedic procedures performed in the United States annually. As the number of patients undergoing these procedures increases so too does the incidence of periprosthetic femur fractures. A number of these periprosthetic fractures occur between two ipsilateral implants, so-called interprosthetic fractures. Recent biomechanical data has challenged the importance of these interprosthetic distances, relating that cortical width and osteoporotic bone are more closely correlated with fracture than interprosthetic distance. The purpose of the current study is to further define the presence of osteoporosis, cortical width (CW) and medullary diameter (MD) as potential predictive factors for interprosthetic femur fractures. METHODS: Current Procedural Terminology (CPT) codes were used to identify a cohort of patients undergoing operative treatment for periprosthetic femur fractures. A review of the medical records identified 23 patients (5 male / 18 female) with a femur fracture between two intramedullary implants. CPT codes were also used to identify a second cohort of 25 patients (8 male / 17 female) having undergone ipsilateral THA and TKA. The intact femoral isthmus was identified radiographically and the MD and CW (mm) were measured. A ratio of MD to CW was also determined. Chart review was undertaken and any diagnosis of osteoporosis was recorded. An independent sample T-test was performed comparing the mean MD, CW, and the ratio of MD:CW for these groups. Significance was set at p.

OBJECTIVES: To evaluate the association of cephalomedullary nail cutout in trochanteric femur fractures with the presence of the following radiographic variables: lateral wall fracture, posteromedial fragment, angular malreduction, residual basicervical fracture gapping, screw placement, and tip-apex distance. DESIGN: Retrospective review. SETTING: Academic medical center. PATIENTS: A total of 362 patients were included in the study. The average age was 83 years and the majority was female. All sustained low-energy trochanteric femur fractures treated operatively with cephalomedullary nails. Minimum radiographic follow-up was 3 months, with an average of 11 (range 3-88) months. INTERVENTION: Cephalomedullary nailing with either a lag screw or helical blade. MAIN OUTCOME MEASURES: Cutout of the lag screw or helical blade. RESULTS: A total of 22 (6%) cutouts occurred. Univariate analysis showed significantly (P ≤ 0.01) more frequent cutout with fracture of the lateral wall, posteromedial fragment, residual gapping (>3 mm) at basicervical component, neck-shaft malreduction >5 degrees varus or 15 degrees valgus, and tip-apex distance >25 mm, and superior screw/blade positioning. There was no difference with unstable fracture pattern (P = 0.58) or fellowship training (P = 0.21). Multivariate regression analysis demonstrates that lateral wall fracture (Odds ratios [OR] = 8.0, 95% confidence interval [CI], 2.4-27.1), neck-shaft malreduction (OR = 4.3, CI, 1.3-14.7), and residual basicervical gapping (OR = 3.6, CI, 1.0-13.0) were associated with fixation cutout. CONCLUSIONS: Risk factors for cutout of trochanteric fractures in our study can be viewed as modifiable or nonmodifiable factors. Statistically significant factors included lateral wall fracture (nonmodifiable) as well as basicervical gapping and malreduction (modifiable). LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Genome-wide association studies have identified thousands of variants that are associated with numerous phenotypes. One such variant, rs13266634, a nonsynonymous single nucleotide polymorphism in the solute carrier family 30 (zinc transporter) member eight gene, is associated with a 53% increase in the risk of developing type 2 diabetes (T2D). We hypothesized that individuals with the protective allele against T2D would show a positive response to short-term and long-term resistance exercise. Two cohorts of young adults-the Eccentric Muscle Damage (EMD; n = 156) cohort and the Functional Single Nucleotide Polymorphisms Associated with Muscle Size and Strength Study (FAMuSS; n = 874)-were tested for association of the rs13266634 variant with measures of skeletal muscle response to resistance exercise. Our results were sexually dimorphic in both cohorts. Men in the EMD study with two copies of the protective allele showed less post-exercise bout strength loss, less soreness, and lower creatine kinase values. In addition, men in the FAMuSS, homozygous for the protective allele, showed higher pre-exercise strength and larger arm skeletal muscle volume, but did not show a significant difference in skeletal muscle hypertrophy or strength with resistance training.
