RESUMO
OBJECTIVES: The primary objective of this study was to analyze the relationship of percentage of surgical overlap with patient outcomes to determine if a detrimental level of overlap exists. BACKGROUND: Overlapping surgery is defined as 1 attending physician supervising 2 or more operative cases simultaneously, without the critical portions of the cases occurring concurrently. To date, no study has examined the relationship of percent overlap, or the percentage of 1 case that is spent overlapping with another, to outcomes, efficiency, safety, and complications. METHODS: This study is a retrospective cohort study conducted at a large tertiary referral center. The primary outcomes of interest included operative duration, in-hospital mortality, 30-day readmission, and patient safety indicators (PSIs). The Cochran-Armitage test for trend was used to evaluate the outcomes of interest. P values of ≤0.05 were considered statistically significant. RESULTS: A total of 87,426 cases were included in this study. There were 62,332 cases without overlap (Group 0), 10,514 cases with 1% to 25% overlap (Group 1), 5303 cases with 26% to 50% overlap (Group 2), 4296 cases with 51% to 75% overlap (Group 3), and 4981 cases with >75% overlap (Group 4). In-hospital mortality decreased as overlap increased ( Ptrend <0.0001). Operative time increased with increasing overlap ( Ptrend <0.0001) while readmission rates showed no statistical significance between groups ( Ptrend =0.5078). Rates of PSIs were lower for Groups 1, 2, and 3 (1.69%, 2.01%, and 2.08%) when compared to Group 0 (2.24%). Group 4 had the highest rate of PSIs at 2.35% ( P =0.0086). CONCLUSION: Overlapping surgery was shown to have reduced in-hospital mortality and similar PSI and readmission rates when compared to nonoverlapping cases. Operative time was shown to increase in overlapping surgeries when compared to nonoverlapping surgeries. The results from this study indicate that the percentage of surgical overlap does not detrimentally affect most patient outcomes, especially with overlap of <75%.

BACKGROUND: The Broström Gould procedure is the gold standard for repair of lateral ankle ligament injury and ankle instability. This procedure has demonstrated excellent short- and long-term outcomes in the orthopedic literature. Arthroscopic Broström Gould techniques have become increasingly popular among some foot and ankle orthopedic surgeons. Typically, this technique requires standard anteromedial and anterolateral portals along with an accessory lateral working portal. The exact location of this portal is variable within the available described surgical techniques. The objective of this cadaveric study is to establish a standard entry point for and to assess the safety of the accessory lateral portal with respect to nearby anatomical structures. METHODS: Ten fresh-frozen below-knee cadaver specimens were used. The location of the accessory lateral portal was created 1.5 cm anterior to the distal tip of the fibula. A small vertical incision was made at this point, followed by insertion of a Kirschner wire into the joint. The wire was then gently impacted into the fibula. Superficial dissection was subsequently carried out around the entry point to identify the peroneal tendons, superficial peroneal nerve branches, and sural nerve branches. Structures were marked with colored push pins, and distance was measured between the nearest edge of the Kirschner wire and each of the three anatomic structures listed. Any instances of structural contact or damage were documented. RESULTS: The average distance from the Kirschner wire to the peroneal tendon was 16.1 (±4.41) mm. The average distance from the wire to the superficial peroneal nerve and sural nerve was 13.11 (±6.79) mm and 12.33 (±4.08) mm, respectively. There were no instances of injury to any of the studied structures. However, there was a notable amount of variability in the proximity of structures in question for each cadaver. A branch of the superficial peroneal nerve was measured as close as 2 mm and as far as 24 mm in separate cadaver specimens. CONCLUSION: Arthroscopic Broström Gould procedures are a safe and effective method for lateral ankle ligamentous repair but are not without risk. Accessory lateral portal placement is relatively safe but should be meticulously executed to avoid damage to nearby anatomical structures.

BACKGROUND: The National COVID Cohort Collaborative (N3C) is an innovative approach to integrate real-world clinical observations into a harmonized database during the time of the COVID-19 pandemic when clinical research on ankle fracture surgery is otherwise mostly limited to expert opinion and research letters. The purpose of this manuscript is to introduce the largest cohort of US ankle fracture surgery patients to date with a comparison between lab-confirmed COVID-19-positive and COVID-19-negative. METHODS: A retrospective cohort of adults with ankle fracture surgery using data from the N3C database with patients undergoing surgery between March 2020 and June 2021. The database is an NIH-funded platform through which the harmonized clinical data from 46 sites is stored. Patient characteristics included body mass index, Charlson Comorbidity Index, and smoking status. Outcomes included 30-day mortality, overall mortality, surgical site infection (SSI), deep SSI, acute kidney injury, pulmonary embolism, deep vein thrombosis, sepsis, time to surgery, and length of stay. COVID-19-positive patients were compared to COVID-19-negative controls to investigate perioperative outcomes during the pandemic. RESULTS: A total population of 8.4 million patient records was queried, identifying 4735 adults with ankle fracture surgery. The COVID-19-positive group (n=158, 3.3%) had significantly longer times to surgery (6.5 ± 6.6 vs 5.1 ± 5.5 days, P = .001) and longer lengths of stay (8.3 ± 23.5 vs 4.3 ± 7.4 days, P < .001), compared to the COVID-19-negative group. The COVID-19-positive group also had a higher rate of 30-day mortality. CONCLUSION: Patients with ankle fracture surgery had longer time to surgery and prolonged hospitalizations in COVID-19-positive patients compared to those who tested negative (average delay was about 1 day and increased length of hospitalization was about 4 days). Few perioperative events were observed in either group. Overall, the risks associated with COVID-19 were measurable but not substantial.Level of Evidence: Level III, retrospective cohort study.
RESUMO
We present the first reported case of septic prepatellar bursitis with Kingella kingae in a 2-year-old female. Although it is a well-established cause of osteoarticular infections in the pediatric population, K. kingae has never been reported as the etiology for septic bursitis. A high index of suspicion is required for the diagnosis given that this organism is difficult to culture and isolate using standard laboratory methods. Our diagnosis was established through bursal fluid analysis, though oropharyngeal polymerase chain reaction (PCR) may be also be considered. Our case also builds upon prior literature suggesting that the pathophysiology of septic bursitis in children differs from that of the adult and may be more comparable to that of pediatric osteomyelitis. As an organism of increasing prevalence, K. kingae should remain high on the differential for osteoarticular or periarticular infections when cultures fail to isolate a distinct pathogen. Early diagnosis and a formal irrigation and debridement, if warranted, are crucial in preventing devastating complications of untreated septic bursitis.
RESUMO
OBJECTIVES: This study compares the intraoperative and postoperative outcomes of the traditional technique of femoral canal reaming to placement of an unreamed 10-mm nail. DESIGN: Retrospective cohort study. SETTING: Academic Level I Trauma Center, Southeastern US. PATIENTS/PARTICIPANTS: Intertrochanteric femur fractures treated with a CMN (January 2016-December 2018) were retrospectively identified. Inclusion criteria were as follows: low-energy mechanism, at least 60 years of age, and long CMN. Exclusion criteria were as follows: short CMN, polytrauma, and subtrochanteric fractures. OUTCOME MEASUREMENTS: Records were reviewed for demographics, hematologic markers, transfusion rates, operative times, and postoperative complications. Variables were assessed with a χ or Student T-test. Significance was set at 0.05. RESULTS: Sixty-five patients were included (37 reamed and 28 unreamed), with a mean age of 76.2 years and mean body mass index of 25.1. Between the reamed and unreamed groups, respectively, mean nail size was 11.0 (SD 1.1) and 10.0 (SD 0.0), P < 0.001; mean blood loss was 209.1 mL (SD 177.5) and 195.7 mL (SD 151.5), P = 0.220; 55% (21/38), and 43% (12/28) were transfused, P = 0.319; operative time was 98.2 (SD 47.3) and 81.5 minutes (SD 40.7); P = 0.035. Changes in hemoglobin/hematocrit were not significant between the study groups. Two patients from the reamed group experienced implant failure due to femoral head screw cut out and returned to the operating room. Two patients from the unreamed group returned to operating room for proximal incision infection, without implant removal. One reamed patient and 2 unreamed patients died before 6-month follow-up. CONCLUSIONS: Unreamed CMNs for geriatric intertrochanteric femur fractures provide shorter operative times with no difference in perioperative complications. Both reamed and unreamed techniques are safe and effective measures for fixation of these fractures. LEVEL OF EVIDENCE: Therapeutic Level III.

BACKGROUND: There is hesitancy to administer nonsteroidal anti-inflammatories (NSAIDs) within the postoperative period following fracture care due to concern for delayed union or nonunion. However, aspirin (ASA) is routinely used for chemoprophylaxis of deep vein thrombosis (DVT) and is gaining popularity for use after treatment of ankle fractures. The current study examines the incidence of nonunion of operative ankle fractures and risk of DVT in patients who did and did not receive postoperative ASA. METHODS: A retrospective chart review was performed on all patients treated between 2008 and 2018 for ankle fractures requiring operative fixation by three Foot and Ankle fellowship trained orthopaedic surgeons at a single institution. Demographics, preoperative comorbidities, and postoperative medical and surgical complications were compared between patients who did and did not receive ASA postoperatively. For both groups, union was evaluated by clinical exam as well as by radiograph, for those with 6-week, 12-week, or 24-week follow-up. RESULTS: Five-hundred and six patients met inclusion criteria: 152 who received ASA and 354 who did not. Radiographic healing at six weeks was demonstrated in 95.9% (94/98) and 98.6% (207/210) respectively (p-value .2134). There was no significant difference in time to radiographic union between groups. The risk of postoperative DVTs in those with and without ASA was not significantly different (0.7% (1/137) vs 1.2% (4/323), respectively; p-value .6305). CONCLUSION: Postoperative use of ASA does not delay radiographic union of operative ankle fractures or affect the rate of postoperative DVT. This is the first and largest study to examine the effect of ASA on time to union of ankle fractures. LEVEL OF EVIDENCE: III.

BACKGROUND: Intra-articular fractures of the calcaneus are a common injury to the hindfoot following high-energy trauma to the lower extremity. Treatment of these fractures has evolved. Due to the concern of wound complications associated with extensile open treatment, smaller incision techniques, such as the sinus tarsi approach, are increasing in popularity. A number of fixation strategies are utilized with this approach, and it is unknown which most accurately restores radiographic alignment. The purpose of this study was to compare the postoperative radiographic outcomes of a plate and screw construct versus a cannulated screw construct when using the sinus tarsi approach for open reduction and internal fixation (ORIF) of calcaneus fractures. METHODS: After institutional review board approval, records for all patients treated surgically at our institution for calcaneus fractures from 2012 to 2017 were reviewed. Inclusion criteria were intra-articular calcaneus fractures, patients aged 18 years or older, and use of the sinus tarsi approach. Exclusion criteria were open fractures and fractures with less than 6 weeks of postoperative weightbearing, which were excluded for radiographic outcomes. A total of 51 fractures underwent ORIF using cannulated screws alone (group 1), and 23 fractures underwent ORIF using a sinus tarsi plate (group 2). Sixty-one fractures (41 vs 20, respectively) met criteria for radiographic comparison. The primary outcomes of interest included pre- and postoperative Bohler and Gissane angles, wound complications, unplanned return to the operating room (OR), and cost comparison. RESULTS: There was no statistically significant difference between preoperative Bohler angles for group 1 (14.4 degrees) versus group 2 (12.2 degrees) (P = .44), nor was there a significant difference between postoperative Bohler angles for group 1 (30.1 degrees) versus group 2 (27.1 degrees) (P = .14). Similarly, preoperative Gissane angles for group 1 (130.5 degrees) and group 2 (133.4 degrees) (P = .54) and postoperative Gissane angles for group 1 (118.2 degrees) and group 2 (119.8 degrees) (P = .44) showed no statistically significant difference. There were a total of 3 wound complications in group 1 versus 2 wound complications in group 2 (P = .66). There was no statistically significant difference in operative duration (P = .97) or the number of unplanned returns to the OR between the 2 groups (P = .68). Based on the implants used at this institution, and depending on the number of screws used, the estimated cost range of a plate construct was $1070 to $1235, while the estimated cost range of a cannulated screw construct was $717 to $1264. CONCLUSION: When comparing the cannulated screw and plate and screw fixation techniques, there was no difference in restoration of the Bohler and Gissane angles. Furthermore, the amount of angular correction achieved by initial reduction showed no statistically significant difference between groups, and the amount of reduction lost between initial and final postoperative radiographs showed no statistically significant difference between groups. With regard to the 2 techniques, there was no statistically significant difference in rates of postoperative complications and return to the OR. Our data suggest that fixation using cannulated screws alone versus sinus tarsi plate provides similar radiographic outcomes and risk of complications. The 2 techniques were also similar in terms of implant costs. Our results indicate that either technique effectively improved radiographic parameters. LEVEL OF EVIDENCE: Level III, retrospective comparative study.
