RESUMO

Background: Posterior malleolar involvement can drastically affect patient outcomes. Literature has supported the use of preoperative Computed Tomography (CT) to assess posterior malleolar fracture morphology. The purpose of this study is to determine whether preoperative CT is associated with significant improvement in surgical time, postoperative complications, reoperation rates in trimalleolar ankle fractures. Surgeons were also asked to complete survey regarding use of CT scans to gauge utility preoperatively. Methods: Adult patients with trimalleolar ankle fractures who underwent operative fixation between 2018-2020 were retrospectively reviewed. Primary outcomes included surgical time, postoperative complications, and reoperations. Secondary outcome was presence of posterior malleolar fixation. 15 surgeons who performed ankle ORIF were surveyed to gain information regarding why or why not preoperative CT scan was obtained. Results: 288 patients with trimalleolar ankle fractures were included, 94 had preoperative CT scans (32.6%). No significant differences found in patient age, gender, BMI, smoking status between the groups that did and did not have preoperative CT scan. No significant differences were observed in AO/OTA classification between groups. Average surgical time was significantly higher in group that received a preoperative CT (114 without CT vs. 145 with CT, p<0.05). Complications (10.3% no CT vs 7.4% with CT, p=0.55) and reoperations (6.7% without CT vs. 7.4% with CT, p=0.16) not significantly different between groups. No significant difference was observed in rate of posterior malleolus fixation between groups (43.8% without CT vs 39.4% with CT; p=0.52). Of surveyed surgeons, 87% reported they don't routinely obtain preoperative CT scan for trimalleolar ankle fractures. Most common reasons for preoperative scans were deciding on approach/positioning, assessing for impaction, determining the size of the posterior malleolus. Conclusion: Although preoperative CT scans are obtained in one third of patients with operative trimalleolar ankle fractures, we did not find an improvement in surgical time, complications, and reoperation. Level of Evidence: III.

RESUMO

INTRODUCTION: We present a case series of proximal junctional failure due to a Chance-type fracture. METHODS: This is a retrospective review of patients who developed proximal junctional kyphosis because of Chance-type proximal junctional failure after spinal fusion for adult spinal deformity. RESULTS: Fifteen patients were identified (4M:11F). The average age was 61.4 years (range, 39 to 77). The mean time to fracture identification was 25.4 days (range, 3 to 65). The average number of levels instrumented was 6.7 (range, 2 to 17). No patients had antecedent trauma before fracture onset. In 67% of cases with a lumbar upper instrumented vertebra (UIV), there was overcorrection of lumbar lordosis (LL) and/or lower LL. The five cases with a lower thoracic UIV had undergone notable correction of preoperative thoracolumbar junction kyphosis. 14 of 15 patients were treated with extension of fusion. Pedicle screws at the fracture level were salvaged by changing to an anatomic trajectory. CONCLUSION: Continued pain at 6 to 12 weeks with radiographs showing an increased proximal junctional angle and cephalocaudal pedicle widening at the UIV should raise suspicion for this unique fracture pattern. A CT scan is recommended. Low bone density, LL and/or lower LL overcorrection, and selection of lower thoracic UIV in the setting of notable thoracolumbar junction correction may contribute to fracture risk.

RESUMO

CASE: We report a 67-year-old healthy man who sustained bilateral hyper-plantarflexion injuries falling off a ladder that resulted in bilateral tibialis anterior tendon tears one month prior to presentation. His injuries were effectively managed with bilateral delayed operative treatment. After non-weightbearing for three months, the patient was subsequently permitted to full weight bear in CAM boots for three months. At three-year follow-up he was fully functional with excellent Foot and Ankle Ability Measure (FAAM scores). CONCLUSION: The management delayed tibialis anterior tendon ruptures, whether due to traumatic or degenerative mechanisms is challenging and surgical repair can be effective when this injury occurs bilaterally.

RESUMO

OBJECTIVE: Sacroiliac joint (SIJ) fusion utilizing intraoperative navigation requires a standard reference frame, which is often placed using a percutaneous pin. Proper placement ensures the correct positioning of SIJ fusion implants. There is currently no grading scheme for evaluation of pin placement into the pelvis. The purpose of this study was to evaluate the occurrence of ideal percutaneous pin placement into the posterior ilium during navigated SIJ fusion. METHODS: After IRB approval was obtained, electronic medical records and intraoperative computed tomography images of patients who underwent navigated SIJ fusion by the senior author between October 2013 and January 2020 were reviewed. A pin placement grading scheme and the definition of "ideal" placement were developed by the authors and deemed acceptable by fellow attending surgeons. Six attending surgeons completed two rounds of pin placement grading, and statistical analysis was conducted. RESULTS: Of 90 eligible patients, 73.3% had ideal pin placement, 17.8% medial/lateral breach, and 8.9% complete miss. Male patients were 3.7 times more likely to have ideal placement than females (p < 0.05). There was no relationship between BMI, SIJ fusion laterality, or pin placement laterality and ideal placement. Interobserver reliability was 0.72 and 0.70 in the first and second rounds, respectively, and defined as "substantial agreement." Intraobserver reliability ranged from 0.74 (substantial agreement) to 0.92 (almost perfect agreement). CONCLUSIONS: Nonideal pin placement occurred in 26.7% of cases, but a true "miss" into the sacrum was rare. Ideal pin placement was more likely in males and was not associated with BMI, SIJ fusion laterality, or pin placement laterality. The grading scheme developed has high intraobserver and interobserver reliability, indicating that it is reproducible and can be used for future studies. When placing percutaneous pins, surgeons must be aware of factors that can decrease placement accuracy, regardless of location.

RESUMO

INTRODUCTION: Cephalomedullary nail (CMN) length for intertrochanteric femur fractures without subtrochanteric extension has been an ongoing debate. The authors hypothesize that increasing nail length would result in increasing surgical time, greater incidence of acute kidney injury (AKI), postoperative anemia, and blood loss requiring transfusion due to increased intramedullary reaming and pressurization of the canal with nail insertion. METHODS: A retrospective chart review of patients aged 65 years or older who underwent CMN for low-energy intertrochanteric femur fractures from 2010 to 2018 was undertaken. Patient demographic data, comorbidities, case duration, postoperative hospital length of stay (LOS), and laboratory data, including serum creatinine, hemoglobin, and hematocrit, were collected for analysis. The following outcome measures were compared: postoperative pneumonia, cardiac complications, sepsis, reintubation/intensive care unit stay, pulmonary embolism, stroke, postoperative AKI, 30-day hospital readmission, 30-day return to operating room, 30-day mortality, 1-year mortality, postoperative anemia (hemoglobin <7 g/dL), and blood transfusion. RESULTS: A total of 247 patients were analyzed (short = 48, intermediate = 39, and long = 160). No notable difference was observed in postoperative pneumonia, cardiac complications, sepsis, reintubation/intensive care unit stay, pulmonary embolism, stroke, mean total hospital LOS, mean postoperative hospital LOS, rate of postoperative AKI, 30-day readmission, 30-day return to operating room, 30-day mortality, or 1-year mortality. Patients receiving long nails had significantly higher rates of postoperative anemia (P = 0.0491), blood transfusion (P = 0.0126), and mean procedure length (P = 0.0044) compared with the two other groups. DISCUSSION: Patients receiving long nails had markedly higher rates of postoperative anemia and blood loss requiring blood transfusion with markedly longer mean procedure length than patients receiving short and intermediate CMNs. Long nails did not result in an increase in other complications evaluated.

RESUMO

As the Coronavirus 2019 (COVID-19) pandemic evolves, it is critical to understand how patients' feelings and perceptions have changed. The aim of this study was to understand current feelings and concerns about seeking and receiving orthopaedic care 9 mo into the global pandemic. METHODS: Utilizing a survey developed to evaluate the attitudes and beliefs from healthcare respondents about receiving care during the COVID-19 pandemic, an updated and revised version, evaluating changes in perception of respondents 9 mo into the pandemic, was distributed to a group of panelists by email. RESULTS: Out of 1200 individuals, 197 (16%) completed the survey. A majority of respondents reported high level of comfort in the immediate or near-term receiving care in an orthopaedic clinic, urgent care clinic specifically for orthopaedics, or in an emergency room. Six percent of respondents reported a delay in seeking orthopaedic care despite COVID-19 concerns that occurred between studies. Respondents reported their primary reason for delaying care was because of concerns for risk of COVID-19 exposure from other patients (83%). More than 75% of respondents stated they are "extremely" or "very" likely to get the COVID-19 vaccine when it becomes available to the public. Respondents had a generally negative outlook on pandemic efforts locally to globally. CONCLUSIONS: Despite dismal overall perceptions regarding the outlook of the pandemic; consumers are becoming increasingly comfortable obtaining orthopaedic care. The ability of healthcare providers and practices to adherence to safety protocols will remain essential to maintaining consumer trust and confidence. LEVEL OF EVIDENCE: Level IV.

RESUMO

SUMMARY: Treatment principles in the management of radial shaft fractures, congruent with all fracture care, are to restore anatomy and function of the limb. Radial shaft fractures are unique in that preserving the anatomic bow of the radius, which allows for its rotation around the ulna during pronation and supination, is essential for proper function. The 2 main approaches for exposure of the proximal or middle third radial diaphyseal fractures are the volar "Henry" and the dorsal "Thompson." This article highlights the benefits of the dorsal Thompson approach, describes the key points of the operative technique, which allow for protection of the posterior interosseous nerve, and provides an overview of the measurable outcomes when using this approach. In the accompanying video, the steps of operative exposure to the proximal radial shaft with careful avoidance of the posterior interosseous nerve are demonstrated.

RESUMO

OBJECTIVE: Examine factors associated with fixation failure in patients treated with superior intramedullary ramus screws. DESIGN: Retrospective. SETTING: Single, Level 1 trauma center. PATIENTS: Unstable pelvic ring fractures amenable fixation that included superior intramedullary ramus screws. INTERVENTION: Percutaneously inserted intramedullary superior ramus screw fixation of superior pubic ramus (SPR) fractures. MAIN OUTCOME MEASUREMENTS: Loss of reduction (LOR) of the SPR fracture defined as >2 mm displacement on pelvic radiographs at any time point in follow-up. RESULTS: Two hundred eighty-five fractures in 211 patients (age 44, 95% confidence interval 40.8%-46.4%, 59.3% women, 55.1% retrograde screws) were included in the analysis. 14 (4.9%) of fractures had LOR. Patients were significantly more likely to have LOR as age increased (P = 0.01), body mass index (BMI) increased (P = 0.01), and if they were women (P < 0.01). There was a significantly decreased LOR (P < 0.01) as fractures moved further from the pubis symphysis. Retrograde screws were significantly (P < 0.01) more likely to have LOR. In SPR fractures treated with retrograde screws, failure was significantly associated with increasing BMI (P = 0.02), the presence of an inferior ramus fracture (P = 0.02), and trended toward significance with increasing age (P = 0.06), and decreased distance from the symphysis (P = 0.07). CONCLUSIONS: Superior ramus screws are associated with a low failure rate (4.9%), which is lower than previously reported. Retrograde screw insertion, distance from the symphysis, increasing age, increasing BMI, decreased distance from the symphysis, and ipsilateral inferior ramus fractures were predictors of failure. In these patients, alternative modalities should be considered, although low rates of failure can still be expected. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

PURPOSE: The Internet is a resource that patients can use to learn about their injuries, treatment options, and surgeon. Previously, it was demonstrated that orthopaedic trauma patients are unlikely to use a reliable, provided source. It is unknown however, if patients are seeking information from elsewhere. The purpose of this study was to determine if orthopaedic trauma patients utilize the Internet and what websites are utilized. Our hypothesis was that the majority of patients use the Internet and when they do, are unlikely to use a reliable source. METHODS: Orthopaedic trauma patients were surveyed in clinic at a Level I trauma center in the United States. The survey queried demographics, injury information, Internet access, and eHealth Literacy Scale (eHEALS). Data were analyzed using t-tests, Chi-squared tests, and a multivariate logistic regression, as appropriate. RESULTS: 138 patients with a mean age of 47.1 years (95% confidence interval: 44.0-50.3; 51.1% female) were included in the analysis. Despite 94.1% reporting access, only 55.8% of trauma patients used the Internet for information about their injury. Of those, 64.5% used at least one unreliable source. WebMD (54.8%) was the highest utilized website. Age, sex, employment, and greater eHEALS score were associated with increased Internet use (p<0.001). CONCLUSION: The Internet has potential to be a useful, low cost, and readily available informational source for orthopaedic trauma patients. This study illustrates that a majority of patients seek information from the Internet after their injury, including unreliable websites like Wikipedia and Facebook. Our study emphasizes the need for active referral to trusted websites and initiation of organizational partnerships (e.g. OTA/AAOS) with common content providers (e.g. WebMD) to provide patients with accurate information about their injury and treatment. LEVEL OF EVIDENCE: Prognostic, Level II.

RESUMO

INTRODUCTION: The early generations of proximal tibial locking plates demonstrated inferior results when compared to dual plating in bicondylar tibial plateau fractures with posteromedial fragments (PMF). Modern plates have multiple rows of locking screws and variable angle technology -which tote the ability to capture the PMF. The purpose of this study was to determine if the modern plates could capture the PMF in a large series of bicondylar tibial plateau fractures. MATERIALS & METHODS: Axial computer topography (CT) scans of 114 bicondylar tibial plateau fractures with PMF were analyzed. Five proximal tibia locking plates-in seven total configurations-were applied to radiopaque tibiae models. All possible screws were placed. Templates of screw trajectories were created based on the model CT scans. These were superimposed onto patient CT scan images to assess for screw penetration into the PMF. Number of screws fully within the PMF were recorded. Capture of the PMF was defined as having at least two screws within the fragment. RESULTS: On average, all plates were able to capture 81.6% of PMF with an average of 3.77 [95% Confidence Interval (CI): 3.47-4.07] screws. However, their ability to capture all fragments varied greatly, from 55.7%-95.2% in fixed angle constructs. Overall, variable angle constructs had a significantly higher capture rate (98.5% vs. 74.9%; p<0.0001) and more screws in the PMF (5.88 [95% CI: 5.58-6.17] vs 2.93 [95% CI: 2.62-3.24]; p<0.0001) when compared to fixed angle constructs. CONCLUSION: Newer generation locking plates vary greatly in their ability to capture the PMF. Variable angle technology dramatically increases the ability to capture the majority of PMFs. Prior biomechanical and clinical studies may yield substantially different results if repeated with these newer implants. Use of newer generation locked plates should not replace thorough preoperative planning.

RESUMO

BACKGROUND: There is concern that regional anesthesia is associated with increased risk of complications, including return to the hospital for uncontrolled pain once the regional anesthetic wears off. METHODS: Retrospective database review of patients who underwent open reduction and internal fixation of a closed ankle fracture from 2014-16 who received general anesthesia alone (GA) or general anesthesia plus regional anesthesia (RA). RESULTS: 9459 patients met inclusion criteria. Patients in the RA group had significantly longer operative duration in both inpatient (GAI=71min vs RAI=79min, p=0.002) and outpatient setting (GAO=66min vs RAI=72min, p<0.001), lower overall LOS (GA=1.7 days vs RA=1.1 days, p<0.001), and higher readmission rate for pain (RAO=4 [0.3%] vs GAO=1 [0.0%], p=0.007). CONCLUSIONS: Patients who received supplemental regional anesthesia had shorter hospital LOS, increased operative time, and increased readmission rates for rebound pain. However, the small number of patients needing readmission are not clinically significant demonstrating that regional anesthesia is safe, effective and readmission for rebound pain should not be a concern. LEVEL OF EVIDENCE: III.

RESUMO

INTRODUCTION: Shoulder dislocation is a costly problem and can have a high risk for recurrent instability after initial dislocation based on well-defined patient characteristics. Patients with recurrent instability can be treated with shoulder stabilizing procedures. Although more costly, surgery may decrease the overall health care burden of managing a patient with multiple shoulder dislocations nonoperatively. METHODS: We performed a retrospective chart review of all patients who presented to the emergency department (ED) with a diagnosis of a shoulder dislocation at a level 1 academic trauma center during the year 2016. Patient information regarding the current dislocation episode, previous dislocations, shoulder surgeries, and postreduction follow-up was gathered. These data were then used to determine the average cost of an ED presentation for a shoulder dislocation episode as obtained from the hospital finance department. The average cost of shoulder stabilization surgery was used to conduct a cost-benefit analysis of operative vs. nonoperative management. RESULTS: Data were collected on 104 individuals who presented to the ED with shoulder dislocations. Of these, 65 were primary dislocations and 39 were recurrent dislocations. Twelve patients underwent shoulder stabilization surgery after their ED presentation. The average cost to the institution for an ED visit requiring the closed reduction of a shoulder dislocation was $2207 ($973.21 without sedation and $3744 with conscious sedation). The average cost of a shoulder stabilization procedure performed at this same institution was $7807. DISCUSSION AND CONCLUSION: Although shoulder stabilization has a higher cost on the front end, this intervention results in cost savings if it prevents 2-3 future shoulder dislocations resulting in ED visits. These findings suggest that, for patients with a high risk for recurrent instability, not only would stabilization surgery help prevent subsequent dislocation events but would also minimize health care costs.

RESUMO

OBJECTIVE: To determine whether suprapatellar nailing (SPN) over time can decrease operative time and radiation exposure when compared with infrapatellar nailing (IPN) of tibial shaft fractures. DESIGN: Retrospective. SETTING: Single, Level 1 trauma center. PATIENTS: Extra-articular adult tibial shaft fractures treated with intramedullary nailing alone within a 7-year period. INTERVENTION: Patients were treated with SPN or IPN techniques based on the discretion of the operating surgeon. MAIN OUTCOME MEASUREMENTS: Operative time and radiation exposure. RESULTS: Three hundred forty-one fractures (SPN: 177, IPN: 164) were included in the analysis. No differences in patient body mass index, sex, or open fracture incidence existed between the 2 groups. A significant difference in average operative time (IPN 130 minutes vs. SPN 110 minutes, P < 0.01), fluoroscopy time (IPN 159 minutes vs. SPN 143 minutes, P = 0.02), and radiation dose (IPN 8.6 mGy vs. SPN 6.5 mGy, P < 0.01) existed between IPN and SPN. Early tibias treated with SPN had similar operative times (P = 0.11), fluoroscopy time (P = 0.94), and radiation dose (P = 0.34) compared with IPN. Later SPN patients had significantly lower operative time (P = 0.03), fluoroscopy time (P < 0.01), and radiation dose (P < 0.013) compared with earlier SPN. Regression analysis revealed with the increased use of SPN, operative time, fluoroscopy time, and radiation dose significantly decreased (P = 0.018, 0.046, 0.011). CONCLUSIONS: Tibia fractures treated with SPN have significantly decreased operative times and radiation exposure compared with those treated with IPN, after allowing time for the surgeon to gain sufficient experience with the technique. The surgeon should consider this when deciding to adopt this technique. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

OBJECTIVE: The purpose of this study is to investigate if preoperative opioid use is associated with other predictors of poor outcome and the effect of these factors on complications. We hypothesized that preoperative opioid use (POU) is associated with increased rates of postoperative complications. DESIGN: Retrospective case control study. SETTING: Academic level-1 trauma center. PATIENTS/PARTICIPANTS: Patients with long bone, lower extremity fractures requiring operative fixation. INTERVENTION: N/A. MAIN OUTCOME MEASURES: Postoperative hospital admissions, emergency room (ER) visits, and reoperations. RESULTS: 399 patients (opioid naïve [ON] 80.2%, Age 38, 95% CI 35.9-39.6) were reviewed. Patients who had POU were older (P = 0.004), had higher BMI (P = 0.03), proportion of females (P < 0.001), tobacco use (P < 0.001), proportion of American Society of Anesthesiologist (ASA) class ≥ 3 (P < 0.001), and rates of substance use disorder (SUD) (P < 0.001). POU was associated with prolonged opiate use at 6 months (60.8%), 1 year (43.0%), higher rates of postoperative readmissions (18.1%), ER visits (17.2%), reoperations (17.5%), and complications (Odds Ratio [OR]: 2.4, P < 0.01). The risk of complication increased synergistically with the addition of other predictors: less than a high school education (OR: 4.6, P = 0.001); ASA class ≥3 (OR: 5.6, P < 0.001). All three factors combined also increased risk of complication synergistically (OR: 9.1, P = 0.003). CONCLUSIONS: Our study demonstrates that many predictors of poor outcome frequently accompany POU. POU combined with many of these predictors synergistically increases the risk of complication. Outcomes-based payment models should reflect this expected rate of readmissions, ER visits and complications in this group. Patients with POU should be targeted with multi-disciplinary interventions aimed to modify these risk factors.

RESUMO

OBJECTIVES: To determine whether an in-office exhaled carbon monoxide (CO) monitor can increase interest in smoking cessation among the orthopaedic trauma population. DESIGN: Prospective. SETTING: Level I trauma center. PATIENTS: One hundred twenty-four orthopaedic trauma patients. INTERVENTION: In-office measurement of exhaled CO. MAIN OUTCOME MEASURES: Stage of change, Likert scale score on willingness to quit today, patient's request for referral to a quitline, and increase in readiness to quit. RESULTS: The use of an exhaled CO monitor increased willingness to quit in 71% of participants still smoking and increased willingness to quit on average by 0.8 points on a 10-point Likert scale (P < 0.001). Fifteen percent of patients modified their stage of change toward quitting. Forty percent of patients after exhaled CO monitor requested referral to a quitline, compared with 4% presurvey (P < 0.001). Anecdotally, most participants were very interested in the monitoring device and its reading, expressing concern with the result. The value of exhaled CO was not associated with any measured outcomes. CONCLUSIONS: The use of an exhaled CO monitor increased willingness to quit smoking in 71% of patients, but the effect size was relatively small (0.8 points on a 10-point Likert scale). However, use of the CO monitor resulted in a large increase (40% vs. 4%) in referral to the national Quitline. Use of the Quitline typically increases the chance of smoking cessation by 10 times the baseline rate, suggesting that this finding might be clinically important. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

OBJECTIVES: Determine if using different fluoroscopic views of the knee (Notch or Tangential) improves accuracy of screw lengths assessment compared to the standard posteroanterior (PA). PARTICIPANTS AND METHODS: Orthopaedic surgeons at three ACGME-accredited residency programs were asked via survey to assess screw lengths on PA, femoral notch, and tangential radiographic views. RESULTS: Responders correctly identified screw length using PA, femoral notch, and medial tangential views at rates of 46.75%, 52.27%, and 44.37% respectively. Respondents detected overall screw length discrepancies most accurately using the femoral notch view (Odds Ratio 1.26; 95% confidence interval: 1.07-1.47; P < 0.005). There was no statistical difference between the residents and faculty cohort in ability to detect screw length discrepancy. CONCLUSION: Differentiating distal interlocking screw lengths on traditional imaging (AP/Notch/Tangential) is poor. The femoral notch view significantly improves accuracy in radiographic determination of screw length. The femoral notch view should be used in conjunction with the traditional PA view to maximize sensitivity and specificity for detecting prominent screws.

RESUMO

OBJECTIVE: Symptomatic distal interlocking screws in retrograde femoral nailing are common due the difficulties of imaging the trapezoidal femur. Screws appearing to have appropriate length on imaging may possibly be prominent, creating symptoms. Screw trajectory may influence the degree of this radiographic error. We hypothesize that external rotation of screw trajectory will increase measurement error of screw length. DESIGN: Retrospective. SETTING: Urban Level I Tertiary Trauma Center. PARTICIPANTS: 283 patients with Computer Tomography (CT) scans of the native knee were retrospectively identified. Simulation was done of the trajectory of an interlock at 20 mm and 40 mm proximal to the nail entry point, which represent common screw positions associated/not associated respectively, with removal. The distance between the radiographic medial cortex and the tip of the transverse screw was calculated (D). The angle (Ψ) between the transverse trajectory and a modified trajectory aimed at the most medial cortex to avoid radiographic measurement error was calculated. Geometric modeling was utilized to calculate the measurement error (D) in the event of accidental external rotation. The angle of the medial slope was also measured (Θ). INTERVENTION: Review of CT imaging of normal distal femora. MAIN OUTCOME MEASUREMENTS: CT measurements of distal femora. RESULTS: The mean distance (D) at 20/40 mm was 4.21 [95%CI 4.02-4.402] and 2.03 mm [95%CI 1.78-2.83], respectively (p < 0.0001). The mean angle (Ψ) between the transverse and modified trajectory at 20/40 mm was 12° [95%CI 11.5-12.5] and 9.60° [95%CI 9-10.2], respectively (p < 0.0001). External rotation by a similar amount nearly triples the measured difference (D). The measured medial slope was significantly increased as screws were placed more proximal (Θ20 mm 46.5 vs Θ40 mm: 48.7 °, p < 0.00001). CONCLUSION: The distance between the perceived medial cortex and the tip of the most transverse screw is 4.21 mm and could account for painfully prominent screws. In more proximal screws this distance is decreased. Internal rotation of the screw trajectory 12° can reduce this distance (D), which has implications in nail design. External rotation, amplifies this difference nearly three-fold. Surgeons should avoid external rotation of the aiming arm to prevent prominent screws.

RESUMO

Total knee arthroplasty is a successful surgery for the majority of patients with osteoarthrosis of the knee. Approximately 5% of patients undergoing total knee arthroplasty experience loss of motion or arthrofibrosis. Manipulation under anesthesia (MUA) is generally indicated for patients who do not achieve >90° of flexion by 6-12 weeks postoperatively. Complications from MUA are rare but can be devastating. We describe a novel technique for MUA with no reported major complications in our review of 78 patients. The average flexion improved from 80.0 (±3.8) before manipulation to 115.4 (±2.1) after manipulation. There were no major complications including fracture or extensor mechanism injury.

RESUMO

Bleeding after total knee arthroplasty increases the risk of pain, delayed rehabilitation, blood transfusion, and transfusion-associated complications. The authors compared pre- and postoperative decreases in hemoglobin as a surrogate for blood loss in consecutive patients treated at a single institution by the same surgeon (J.L.C.) using conventional hemostatic methods (electrocautery, suturing, or manual compression) or a gelatin and thrombin-based hemostatic matrix during total knee arthroplasty. Data were collected retrospectively by chart review. The population comprised 165 controls and 184 patients treated with hemostatic matrix. Median age was 66 years (range, 28-89 years); 66% were women. The arithmetic mean ± SD for the maximal postoperative decrease in hemoglobin was 3.18 ± 0.94 g/dL for controls and 2.19 ± 0.83 g/dL for the hemostatic matrix group. Least squares means estimates of the group difference (controls-hemostatic matrix) in the maximal decrease in hemoglobin was 0.96 g/dL (95% confidence interval, 0.77-1.14 mg/dL; P<.0001). Statistically significant covariate effects were observed for preoperative hemoglobin level (P<.0001) and body mass index (P=.0029). Transfusions were infrequent in both groups. The frequency of acceptable range of motion was high (control, 88%; hemostatic matrix, 84%). In both groups, overall mean tourniquet time was approximately 1 hour, and the most common length of stay was 3 to 5 days. No serious complications related to the hemostatic agent were observed. These data demonstrate that the use of a flowable hemostatic matrix results in less reduction in hemoglobin than the use of conventional hemostatic methods in patient undergoing total knee arthroplasty.
