How Does Perioperative Ketorolac Affect Opioid Consumption and Pain Management After Ankle Fracture Surgery?

Opioid-Sparing Nonsteroid Anti-inflammatory Drugs Protocol in Patients Undergoing Intramedullary Nailing of Tibial Shaft Fractures: A Randomized Control Trial

INTRODUCTION

Nonsteroidal anti-inflammatory drugs (NSAIDs) are effective analgesics commonly used in fracture management. Although previously associated with delayed fracture healing, multiple studies have demonstrated their safety, with minimal risks of fracture healing. Given the current opioid crisis in the United States, alternate pain control modalities are essential to reduce opioid consumption. This study aims to determine whether the combination of oral acetaminophen and intravenous ketorolac is a viable alternative to opioid-based pain management in closed tibial shaft fractures treated with intramedullary nailing.

METHODS

We conducted a randomized controlled trial evaluating postoperative pain control and opioid consumption in patients with closed tibial shaft fractures who underwent intramedullary nailing. Patients were randomized into an NSAID-based pain control group (52 patients) and an opioid-based pain control group (44 patients). Visual analog scale (VAS) scores and morphine milligram equivalents (MMEs) were evaluated at 12-hour postoperative intervals during the first 48 hours after surgery. Nonunion and delayed healing rates were recorded for both groups.

RESULTS

A statistically significant decrease in MMEs was noted at every measured interval (12, 24, 36, and 48 hours) in the NSAID group compared with the opioid group ( P -value 0.001, 0.001, 0.040, 0.024, respectively). No significant change in visual analog scale scores was observed at 12, 36, and 48 hours between both groups ( P -value 0.215, 0.12, and 0.083, respectively). A significant decrease in VAS scores was observed at the 24-hour interval in the NSAID group compared with the opioid group ( P -value 0.041). No significant differences in union rates were observed between groups ( P -value 0.820).

DISCUSSION

Using an NSAID-based postoperative pain protocol led to a decrease in opioid consumption without affecting pain scores or union rates. Owing to the minimal risk of short-term NSAID use, their role in the perioperative management of tibia shaft fractures is justified, especially when they reduce opioid consumption markedly.

Ketorolac and bone healing: a review of the basic science and clinical literature

Although the efficacy of ketorolac in pain management and the short duration of use align well with current clinical practice guidelines, few studies have specifically evaluated the impact of ketorolac on bony union after fracture or surgery. The purpose of this study was to review the current basic science and clinical literature on the use of ketorolac for pain management after fracture and surgery and the subsequent risk of delayed union or nonunion. Animal studies demonstrate a dose-dependent risk of delayed union in rodents treated with high doses of ketorolac for 4 weeks or greater; however, with treatment for 7 days or low doses, there is no evidence of risk of delayed union or nonunion. Current clinical evidence has also shown a dose-dependent increased risk of pseudoarthrosis and nonunion after post-operative ketorolac administration in orthopedic spine surgery. However, other orthopedic subspecialities have not demonstrated increased risk of delayed union or nonunion with the use of peri-operative ketorolac administration. While evidence exists that long-term ketorolac use may represent risks with regard to fracture healing, insufficient evidence currently exists to recommend against short-term ketorolac use that is limited to the peri-operative period.

Scheduled Postoperative Ketorolac Does Not Decrease Opiate Use following Free Flap Breast Reconstruction

BACKGROUND

 In the setting of the opioid crisis, managing postoperative pain without the exclusive use of opiates has become a topic of interest. Many hospitals have begun implementing enhanced recovery after surgery protocols to decrease postoperative complications, hospital costs, and opiate utilization. Ketorolac has been added to many of these protocols, but few studies have examined its effects independently.

METHODS

 A retrospective chart review was performed on all patients that received autologous breast reconstruction from October 2020 to June 2022 at an academic institution. We identified patients who did and did not receive postoperative ketorolac. Use of ketorolac was based upon surgeon preference. The two groups were compared in basic demographics, reconstruction characteristics, length of stay, complications, reoperations, and morphine milligram equivalents (MMEs).

RESULTS

 One-hundred ten patients were included for the analysis, with 55 receiving scheduled postoperative ketorolac and 55 who did not receive ketorolac. There were seven incidences of postoperative complications in each group (12.7%, p = 1.00). The total mean postoperative MMEs were 344.7 for the nonketorolac group and 336.5 for the ketorolac group (p = 0.81). No variable was found to be independently associated with postoperative opiate use. Ketorolac was not found to contribute significantly to any postoperative complication.

CONCLUSION

 In this study, the use of ketorolac did not significantly reduce opiate use in a cohort of 110 patients. Surgeons should consider whether the use of ketorolac alone is the best option to reduce postoperative opiate use following free flap breast reconstruction.

Strategies for Reducing Perioperative Opioid Use in Foot and Ankle Surgery: Education, Risk Identification, and Multimodal Analgesia

There remains a high prevalence and substantial risks of opioid utilization amongst orthopedic patients. The goal of this review is to discuss strategies for responsible opioid use in the perioperative setting following foot and ankle orthopedic surgeries. We will highlight 1) education interventions, 2) risk identification, and 3) non-opioid alternatives for postoperative pain management.

Efficacy and safety of non-steroidal anti-inflammatory drugs (NSAIDs) for the treatment of acute pain after orthopedic trauma: a practice management guideline from the Eastern Association for the Surgery of Trauma and the Orthopedic Trauma Association

Objectives

Fracture is a common injury after a traumatic event. The efficacy and safety of non-steroidal anti-inflammatory drugs (NSAIDs) to treat acute pain related to fractures is not well established.

Methods

Clinically relevant questions were determined regarding NSAID use in the setting of trauma-induced fractures with clearly defined patient populations, interventions, comparisons and appropriately selected outcomes (PICO). These questions centered around efficacy (pain control, reduction in opioid use) and safety (non-union, kidney injury). A systematic review including literature search and meta-analysis was performed, and the quality of evidence was graded per the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. The working group reached consensus on the final evidence-based recommendations.

Results

A total of 19 studies were identified for analysis. Not all outcomes identified as critically important were reported in all studies, and the outcome of pain control was too heterogenous to perform a meta-analysis. Nine studies reported on non-union (three randomized control trials), six of which reported no association with NSAIDs. The overall incidence of non-union in patients receiving NSAIDs compared with patients not receiving NSAIDs was 2.99% and 2.19% (p=0.04), respectively. Of studies reporting on pain control and reduction of opioids, the use of NSAIDs reduced pain and the need for opioids after traumatic fracture. One study reported on the outcome of acute kidney injury and found no association with NSAID use.

Conclusions

In patients with traumatic fractures, NSAIDs appear to reduce post-trauma pain, reduce the need for opioids and have a small effect on non-union. We conditionally recommend the use of NSAIDs in patients suffering from traumatic fractures as the benefit appears to outweigh the small potential risks.

Effectiveness of Topical Ketorolac in Post-hemorrhoidectomy Pain Management: A Clinical Trial

Background

Postoperative pain management is one of the major challenges of surgeons and anesthesiologists.

Objectives

This study aimed to determine the efficacy of topical ketorolac in post-hemorrhoidectomy pain management.

Methods

This clinical trial was conducted on 84 candidates for hemorrhoidectomy (grade-II hemorrhoids) who visited Ali ibn Abi-Talib hospital of Rafsanjan, Kerman, Iran (2020 - 2021). The participants were selected through convenience sampling and randomly assigned to three groups of 28. The subjects were treated in topical (4 mL 0.5% Marcaine + 1 mL ketorolac at the surgical site), intramuscular (4 mL 0.5% Marcaine at the surgical site + 1 mL ketorolac intramuscularly), and control (4 mL 0.5% Marcaine at the surgical site) groups. Pain intensity was measured using the Numerical Pain Rating Scale 1, 6, 12, and 24 hours after surgery. The obtained data were analyzed using two-way repeated measures analysis of variance.

Results

Female and male patients constituted 46.4% and 53.6% of the participants, respectively. The mean pain intensity was significantly lower in the topical group than in intramuscular and control treatments in all four stages of pain assessment (P < 0.001). Some participants were treated with pethidine due to high pain intensity. However, the mean pain intensity gradually reduced over time in all three groups.

Conclusions

Study findings suggested that the topical administration of ketorolac and Marcaine was more effective than Marcaine used alone for relieving pain in patients undergoing hemorrhoidectomy.

Application evaluation of multidisciplinary collaboration model with health care integration in perioperative period of femoral neck fracture

 This study was to analyze application effect of multidisciplinary collaboration model with health-care integration in perioperative period of femoral neck fracture. As a prospective study, 124 patients with femoral neck fracture who underwent artificial joint replacement in our hospital from August 2020 to August 2021 were selected as the study subjects. According to the random allocation, they were divided into the group A (n = 62, multidisciplinary collaboration model with health-care integration) and the group B (n = 62, conventional care) to analyze the clinical value of different intervention measures in perioperative period by comparing the hip joint activity, quality of life and incidence of perioperative complications between the two groups. Compared with group B, the average HHS score and hip joint activity after intervention in group A were notably higher (P < 0.05), the VAS score after intervention was overtly lower (P < 0.001), and the GQOLI-74 score of group A after intervention was visibly higher (P < 0.001), with no overt difference in the overall incidence of perioperative complications between the two groups (P > 0.05). The application of multidisciplinary collaboration model with health-care integration in femoral neck fracture can effectively improve the hip joint function, reduce the severity of pain and benefit patients, and further studies will help to establish a better solution for such patients.

Opioid-Free Forefoot Surgery vs Traditional Perioperative Opiate Regimen: A Randomized Controlled Trial

BACKGROUND

In response to the opioid epidemic, the use of multimodal pain management in orthopaedic surgery is increasing. Efforts to decrease opioid prescribing and opioid consumption among foot and ankle surgical patients are needed. The purpose of this study was to compare the efficacy and adverse events between 2 multimodal pain management pathways for forefoot surgical patients: standard opioid-containing (OC) and opioid-free (OF).

METHODS

This is a single-center noninferior randomized controlled trial of 51 patients undergoing forefoot surgery allocated to one of 2 perioperative pain management treatments: opioid-free, multimodal (OF, n=27 patients), or traditional opioid-containing (OC, n=24 patients). Patient characteristics, creatine markers, pain (numeric rating scale [NRS]), general health (Veterans Rand 12-Item Health Survey [VR-12]), and depression were measured preoperatively. Postoperatively, pain was measured at 24-hour, 2-week, and 6-week time points. Satisfaction with pain control, complications, and general health were measured at 2 and 6 weeks.

RESULTS

The OF group is statistically noninferior to the OC group and reported lower median pain scores at 24 hours (2 [IQR 0, 3] vs 6 [IQR 3.5, 7]; p<.0001) and 2 weeks (2 [IQR 1, 4] vs 4 [IQR 0, 3]; p=.018]. By 6 weeks, pain levels were similar between groups. More than 85% of all patients reported satisfaction with pain level at 2 weeks, which increased to >90% at 6 weeks. The VR-12 scores were similar between groups across all time points. At 2 weeks, 8 patients in each group reported constipation. By 6 weeks, all but 2 OC patients reported resolution. No other adverse events of postoperative wound complications, readmissions, medication reactions, thrombosis, or persistent pain were documented.

CONCLUSION

In forefoot surgery, the opioid-free pain management protocol was statistically noninferior to the opioid-containing protocol in reducing postoperative pain.

Prescription Patterns, Associated Factors, and Outcomes of Opioids for Operative Foot and Ankle Fractures: A Systematic Review

BACKGROUND

Pain management after foot and ankle surgery must surmount unique challenges that are not present in orthopaedic surgery performed on other parts of the body. However, disparate and inconsistent evidence makes it difficult to draw meaningful conclusions from individual studies.

QUESTIONS/PURPOSES

In this systematic review, we asked: what are (1) the patterns of opioid use or prescription (quantity, duration, incidence of persistent use), (2) factors associated with increased or decreased risk of persistent opioid use, and (3) the clinical outcomes (principally pain relief and adverse events) associated with opioid use in patients undergoing foot or ankle fracture surgery?

METHODS

We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for our review. We searched PubMed, Embase, Scopus, Cochrane, and Web of Science on October 15, 2021. We included studies published from 2010 to 2021 that assessed patterns of opioid use, factors associated with increased or decreased opioid use, and other outcomes associated with opioid use after foot or ankle fracture surgery (principally pain relief and adverse events). We excluded studies on pediatric populations and studies focused on acute postoperative pain where short-term opioid use (< 1 week) was a secondary outcome only. A total of 1713 articles were assessed and 18 were included. The quality of the 16 included retrospective observational studies and two randomized trials was evaluated using the Methodological Index for Non-Randomized Studies criteria and the Jadad scale, respectively; study quality was determined to be low to moderate for observational studies and good for randomized trials. Mean patient age ranged from 42 to 53 years. Fractures studied included unimalleolar, bimalleolar, trimalleolar, and pilon fractures.

RESULTS

Proportions of postoperative persistent opioid use (defined as use beyond 3 or 6 months postoperatively) ranged from 2.6% (546 of 20,992) to 18.5% (32 of 173) and reached 39% (28 of 72) when including patients with prior opioid use. Among the numerous associations reported by observational studies, two or more preoperative opioid prescriptions had the strongest overall association with increased opioid use, but this was assessed by only one study (OR 11.92 [95% confidence interval (CI) 9.16 to 13.30]; p < 0.001). Meanwhile, spinal and regional anesthesia (-13.5 to -41.1 oral morphine equivalents (OME) difference; all p < 0.01) and postoperative ketorolac use (40 OME difference; p = 0.037) were associated with decreased opioid consumption in two observational studies and a randomized trial, respectively. Three observational studies found that opioid use preoperatively was associated with a higher proportion of emergency department visits and readmission (OR 1.41 to 17.4; all p < 0.001), and opioid use at 2 weeks postoperatively was associated with slightly higher pain scores compared with nonopioid regimens (β = 0.042; p < 0.001 and Likert scale 2.5 versus 1.6; p < 0.05) in one study.

CONCLUSION

Even after noting possible inflation of the harms of opioids in this review, our findings nonetheless highlight the need for opioid prescription guidelines specific for foot and ankle surgery. In this context, surgeons should utilize short (< 1 week) opioid prescriptions, regional anesthesia, and multimodal pain management techniques, especially in patients at increased risk of prolonged opioid use.

A machine learning algorithm for predicting prolonged postoperative opioid prescription after lumbar disc herniation surgery. An external validation study using 1,316 patients from a Taiwanese cohort

BACKGROUND CONTEXT

Preoperative prediction of prolonged postoperative opioid prescription helps identify patients for increased surveillance after surgery. The SORG machine learning model has been developed and successfully tested using 5,413 patients from the United States (US) to predict the risk of prolonged opioid prescription after surgery for lumbar disc herniation. However, external validation is an often-overlooked element in the process of incorporating prediction models in current clinical practice. This cannot be stressed enough in prediction models where medicolegal and cultural differences may play a major role.

PURPOSE

The authors aimed to investigate the generalizability of the US citizens prediction model SORG to a Taiwanese patient cohort.

STUDY DESIGN

Retrospective study at a large academic medical center in Taiwan.

PATIENT SAMPLE

Of 1,316 patients who were 20 years or older undergoing initial operative management for lumbar disc herniation between 2010 and 2018.

OUTCOME MEASURES

The primary outcome of interest was prolonged opioid prescription defined as continuing opioid prescription to at least 90 to 180 days after the first surgery for lumbar disc herniation at our institution.

METHODS

Baseline characteristics were compared between the external validation cohort and the original developmental cohorts. Discrimination (area under the receiver operating characteristic curve and the area under the precision-recall curve), calibration, overall performance (Brier score), and decision curve analysis were used to assess the performance of the SORG ML algorithm in the validation cohort. This study had no funding source or conflict of interests.

RESULTS

Overall, 1,316 patients were identified with sustained postoperative opioid prescription in 41 (3.1%) patients. The validation cohort differed from the development cohort on several variables including 93% of Taiwanese patients receiving NSAIDS preoperatively compared with 22% of US citizens patients, while 30% of Taiwanese patients received opioids versus 25% in the US. Despite these differences, the SORG prediction model retained good discrimination (area under the receiver operating characteristic curve of 0.76 and the area under the precision-recall curve of 0.33) and good overall performance (Brier score of 0.028 compared with null model Brier score of 0.030) while somewhat overestimating the chance of prolonged opioid use (calibration slope of 1.07 and calibration intercept of -0.87). Decision-curve analysis showed the SORG model was suitable for clinical use.

CONCLUSIONS

Despite differences at baseline and a very strict opioid policy, the SORG algorithm for prolonged opioid use after surgery for lumbar disc herniation has good discriminative abilities and good overall performance in a Han Chinese patient group in Taiwan. This freely available digital application can be used to identify high-risk patients and tailor prevention policies for these patients that may mitigate the long-term adverse consequence of opioid dependence: https://sorg-apps.shinyapps.io/lumbardiscopioid/.

State regulation positively impacts opioid prescribing patterns in ankle fracture surgery: A national and state-level analysis

BACKGROUND

The impact of time and state regulation on opioid prescribing in orthopedic trauma is not well known. The purpose of this study is to evaluate the impact of time and state-level opioid legislation on 90-day perioperative opioid prescribing in ankle fracture surgery from 2010 to 2019.

METHODS

This is a retrospective, cohort study using a national insurance database including commercial insurance, Medicare, Medicaid, and cash pay patients to evaluate 30-day pre-operative to 90-day post-operative opioid prescription filling in 40,286 patients ages 18 and older undergoing Current Procedural Terminology codes 27,766, 27,769, 27,792, 27,814, 27,822, and/or 27,823 between 2010 and 2019 in all 50 United States. The primary study outcome was initial and cumulative perioperative opioid prescription filling and rates of filling and refills over the study timeframe.

RESULTS

Mean first prescription volume has not changed dramatically from 2010 (37 oxycodone 5 mg pills) to 2019 (33.3 oxycodone 5 mg pills). However, cumulative prescriptions within the 30PRE-90POST timeframe have decreased considerably from 2010 (128.5 oxycodone 5 mg pills) to 2019 (70.4 oxycodone 5 mg pills), and cumulative prescription filling in years 2018 and 2019 was significantly less than in 2010. Legislation targeting duration or duration and volume had the largest impacts on initial and cumulative opioid prescribing.

CONCLUSIONS

In ankle fracture surgery, states with opioid prescribing legislation had larger reductions in perioperative opioid prescribing compared to states without opioid legislation. Legislation targeting duration or duration and volume had the largest impacts on opioid prescribing.

Stereotactic Electroencephalography Is Associated With Reduced Pain and Opioid Use When Compared with Subdural Grids: A Case Series

BACKGROUND

Minimally invasive surgery (MIS) has been shown to decrease length of hospital stay and opioid use.

OBJECTIVE

To identify whether surgery for epilepsy mapping via MIS stereotactically placed electroencephalography (SEEG) electrodes decreased overall opioid use when compared with craniotomy for EEG grid placement (ECoG).

METHODS

Patients who underwent surgery for epilepsy mapping, either SEEG or ECoG, were identified through retrospective chart review from 2015 through 2018. The hospital stay was separated into specific time periods to distinguish opioid use immediately postoperatively, throughout the rest of the stay and at discharge. The total amount of opioids consumed during each period was calculated by transforming all types of opioids into their morphine equivalents (ME). Pain scores were also collected using a modification of the Clinically Aligned Pain Assessment (CAPA) scale. The 2 surgical groups were compared using appropriate statistical tests.

RESULTS

The study identified 43 patients who met the inclusion criteria: 36 underwent SEEG placement and 17 underwent craniotomy grid placement. There was a statistically significant difference in median opioid consumption per hospital stay between the ECoG and the SEEG placement groups, 307.8 vs 71.5 ME, respectively (P = .0011). There was also a significant difference in CAPA scales between the 2 groups (P = .0117).

CONCLUSION

Opioid use is significantly lower in patients who undergo MIS epilepsy mapping via SEEG compared with those who undergo the more invasive ECoG procedure. As part of efforts to decrease the overall opioid burden, these results should be considered by patients and surgeons when deciding on surgical methods.

The emergency medicine management of clavicle fractures

BACKGROUND

Clavicle fractures are common. An emergency physician needs to understand the diagnostic classifications of clavicle fractures, have a plan for immobilization, identify associated injuries, understand the difference between treating pediatric and adult patients, and have an approach to multimodal pain control. It is also important to understand when expert orthopedic consultation or referral is indicated.

OBJECTIVE OF THE REVIEW

To provide an evidence-based review of clavicle fracture management in the emergency department.

DISCUSSION

Clavicle fractures account for up to 4% of all fractures evaluated in the emergency department. They can be separated into midshaft, distal, and proximal fractures. They are also classified in terms of their degree of displacement, comminution and shortening. Emergent referral is indicated for open fractures, posteriorly displaced proximal fractures, and those with emergent associated injuries. Urgent referral is warranted for fractures with greater than 100% displacement, fractures with >2 cm of shortening, comminuted fractures, unstable distal fractures, and floating shoulder. Nondisplaced or minimally displaced fractures with no instability or associated neurovascular injury are managed non-operatively with a sling. Pediatric fractures are generally managed conservatively, with adolescents older than 9 years-old for girls and 12 years-old for boys being treated using algorithms that are similar to adults.

CONCLUSIONS

When encountering a patient with a clavicle fracture in the emergency department the fracture pattern will help determine whether emergent consultation or urgent referral is indicated. Most patients can be discharged safely with sling immobilization and appropriate outpatient follow-up.

Do NSAIDs Really Interfere with Healing after Surgery?

Perioperative analgesia should be multimodal to improve pain relief, reduce opioid use and thereby adverse effects impairing recovery. Non-steroidal anti-inflammatory drugs (NSAIDs) are an important non-opioid component of this approach. However, besides potential other adverse effects, there has been a longstanding discussion on the potentially harmful effects of NSAIDs on healing after surgery and trauma. This review describes current knowledge of the effects of NSAIDs on healing of bones, cartilage, soft tissue, wounds, flaps and enteral anastomoses. Overall, animal data suggest some potentially harmful effects, but are contradictory in most areas studied. Human data are limited and of poor quality; in particular, there are only very few good randomized controlled trials (RCTs), but many cohort studies with potential for significant confounding factors influencing the results. The limited human data available are not precluding the use of NSAIDs postoperatively, in particular, short-term for less than 2 weeks. However, well-designed and large RCTs are required to permit definitive answers.

A randomized controlled trial comparing the efficacies of ketorolac and parecoxib for early pain management after total knee arthroplasty

BACKGROUND

Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used to reduce pain after orthopedic surgery. Currently, selective COX-2 inhibitors can provide effective pain reduction with less platelet inhibition compared with conventional NSAIDs. We aimed to compare the analgesic effect and perioperative blood loss (PBL) after total knee arthroplasty (TKA) between ketorolac and parecoxib administration.

METHODS

We conducted a prospective randomized controlled study of 100 unilateral TKAs. The ketorolac group of 50 patients received an intraoperative periarticular injection (PAI) with 100 mg of bupivacaine and 30 mg of ketorolac. Afterwards, 30 mg of ketorolac was intravenously injected every 12 h until 48 h. In the parecoxib group of 50 patients, 20 mg of parecoxib was added to PAI, and the first intravenous dose was 20 mg followed by 40 mg every 12 h. The primary outcomes were visual analog scales (VASs) of postoperative pain, amount of morphine consumption, PBL, and blood transfusion rate.

RESULTS

The ketorolac group had a significantly lower VAS pain score than the parecoxib group at 6 h after TKA (2.38 ± 2.52 vs. 4.12 ± 2.86, P < 0.01). Thereafter, the VAS of both groups and total morphine consumption at 24 and 48 h were comparable. The PBLs of the ketorolac and parecoxib groups were 529.72 ± 263.02 and 402.40 ± 191.47 ml, respectively (P = 0.01). However, the blood transfusion rates between groups were not different.

CONCLUSION

Parecoxib provides comparable analgesic effects to ketorolac. Additionally, perioperative use of parecoxib is safe and is associated with significantly less blood loss after TKA.

Epidemiology, Clinical Assessments, and Current Treatments of Nonunions

PURPOSE OF REVIEW

The failure of bony union following a fracture, termed a fracture nonunion, has severe patient morbidity and economic consequences. This review describes current consensuses and future directions of investigation for determining why, detecting when, and effective treatment if this complication occurs.

RECENT FINDINGS

Current nonunion investigation is emphasizing an expanded understanding of the biology of healing. This has led to assessments of the immune environment, multiple cytokines and morphogenetic factors, and the role of skeletogenic stem cells in the development of nonunion. Detecting biological markers and other objective diagnostic criteria is also a current objective of nonunion research. Treatment approaches in the near future will likely be dominated by the development of specific adjunct therapies to the nonunion surgical management, which will be informed by an expanded mechanistic understanding of nonunion biology. Current consensus among orthopedists is that improved diagnosis and treatment of nonunion hinges first on discoveries at the bench side with later translation to the clinic.

Management of Pain Associated with Fractures

PURPOSE OF REVIEW

The purpose is to review current literature on pain management strategies from initial presentation to postoperative care on common fracture types.

RECENT FINDINGS

- Hip fractures benefit from use of multimodal pain control for early mobility and decreased narcotic requirement. - Distal radius fracture pain during reduction can be managed with hematoma block. Postoperatively, a soft dressing is adequate, and use of a compression glove may improve pain control and edema. - Ankle fractures can be reduced with hematoma block, though use of procedural sedation may reduce reduction attempts for fracture dislocations. - Long bone fracture pain management is trending toward multimodal pain control. Though there is no high-quality evidence, concern that regional anesthesia may mask compartment syndrome has limited its use in high-risk fractures. - The effect of NSAIDs on bone healing has not been conclusively demonstrated. The literature is still inconclusive regarding superiority of either spinal or general anesthesia during operative treatment. Fracture pain control is complex and multifactorial, requiring nuanced clinical judgment in the face of mixed clinical findings.

Utilization of a Novel Opioid-Sparing Protocol in Primary Total Hip Arthroplasty Results in Reduced Opiate Consumption and Improved Functional Status

BACKGROUND

Total hip arthroplasty (THA) candidates have historically received high doses of opioids within the perioperative period; however, the amounts are being continually reduced as awareness of opioid abuse spreads. Here we seek to evaluate the effectiveness of a novel opiate-sparing protocol (OSP) for primary THAs in reducing opiate administrations, while maintaining similar levels of pain control and postoperative function.

METHODS

All patients undergoing primary THA between January 1, 2019 and June 30, 2019 were placed under a novel OSP. Data were prospectively collected as part of standard of care. To assess the primary outcome of opiate consumption, nursing documented opiate administration events were converted into morphine milligram equivalences (MMEs) per patient encounter per 24-hour interval. Postoperative pain and functional status were assessed as secondary outcomes using the Verbal Rating Scale for pain and the Activity Measure for Post-Acute Care scores, respectively.

RESULTS

One thousand fifty primary THAs had received our institution's OSP, and 953 patients were utilized as our historical control. OSP patients demonstrated significantly lower 0-24, 24-48, and 48-72 hours with less opiate administration variance (total MME: Control 75.55 ± 121.07 MME vs OSP 57.10 ± 87.48 MME; 24.42% decrease, P < .001). Although pain scores reached statistical significance between 0 and 12 (Control 2.09 vs OSP 2.36, P < .001), their differences were not clinically significant. Finally, OSP patients demonstrated a trend toward higher Activity Measure for Post-Acute Care scores across all 6 domains (total scores: Control 20.53 ± 3.67 vs OSP 20.76 ± 3.64, P = .18).

CONCLUSION

Implementation of an OSP can significantly decrease the utilization of opioids in the immediate postoperative period. Inpatient opioid administration can be significantly reduced while maintaining a comparable and non-inferior level of pain and function.
