Abstract
Introduction Nonsteroidal anti-inflammatory drugs (NSAIDs) may potentially delay or cause non-union of fractures by inhibiting prostaglandin synthesis. However, studies have shown conflicting results. This systematic review and meta-analysis aim to synthesize current evidence on the potential influence of NSAIDs on bone healing. Methods We conducted a comprehensive search of PubMed, Embase, and Cochrane CENTRAL databases for studies published up to 25 July 2023. Specific keywords included "NSAID," "nonsteroidal anti-inflammatory drug," "cyclooxygenase-2 inhibitor," "bone healing," "non-union," "pseudoarthrosis," "delayed union," and "atrophic bone." Eligible studies included prospective, retrospective, and case-controlled studies assessing the correlation between NSAID use and bone healing outcomes. The leave-one-out approach was used to test the robustness of the meta-analysis results. Results A total of 20 studies with 523,240 patients were included in the analysis. The mean patient age ranged from 6.7 to 77.0 years, with follow-up durations from 3 to 67 months. The meta-analysis revealed no significant difference in non-union or delayed union between NSAID users and non-users [pooled adjusted odds ratio (OR) = 1.11; 95% confidence interval (CI): 0.99-1.23]. Initial analysis identified a significant association between NSAID usage and an increased risk of reoperation, but this association became insignificant upon sensitivity analysis (crude OR = 1.42; 95% CI: 0.88-2.28). Discussion NSAIDs may have a minimal impact on non-union or delayed union risks. However, caution is advised due to the limited number of studies and the absence of a specific focus on NSAID types and dosages. Further research is necessary to better understand the implications of NSAID use on bone healing.

Short-Term Celecoxib Promotes Bone Formation without Compromising Cefazolin Efficacy in an Early Orthopaedic Device-Related Infection: Evidence from a Rat Model. Antibiotics (Basel) 2024; 13:715. [PMID: 39200015 PMCID: PMC11350844 DOI: 10.3390/antibiotics13080715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2024] [Revised: 07/26/2024] [Accepted: 07/26/2024] [Indexed: 09/01/2024] Open
Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are crucial components of multimodal analgesia for musculoskeletal injuries, targeting cyclooxygenase (COX) enzymes (COX-1 and/or COX-2 isoenzymes). Concerns exist regarding their potential interference with bone healing and orthopaedic device-related infections (ODRI), where data are limited. This study aimed to investigate whether the COX-selectivity of NSAIDs interfered with antibiotic efficacy and bone changes in the setting of an ODRI. In vitro testing demonstrated that combining celecoxib (a COX-2 inhibitor) with cefazolin significantly enhanced antibacterial efficacy compared to cefazolin alone (p < 0.0001). In vivo experiments were performed using Staphylococcus epidermidis in the rat proximal tibia of an ODRI model. Long and short durations of celecoxib treatment in combination with antibiotics were compared to a control group receiving an antibiotic only. The long celecoxib treatment group showed impaired infection clearance, while the short celecoxib treatment showed increased bone formation (day 6, p < 0.0001), lower bone resorption (day 6, p < 0.0001), and lower osteolysis (day 6, BV/TV: p < 0.0001; BIC: p = 0.0005) compared to the control group, without impairing antibiotic efficacy (p > 0.9999). Given the use of NSAIDs as part of multimodal analgesia, and considering these findings, short-term use of COX-2 selective NSAIDs like celecoxib not only aids pain management but also promotes favorable bone changes during ODRI.

J Affect Disord 2023; 341:62-66. [PMID: 37634817 DOI: 10.1016/j.jad.2023.08.121] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 08/23/2023] [Accepted: 08/24/2023] [Indexed: 08/29/2023]
Abstract
BACKGROUND Osteomyelitis and major depressive disorder (MDD) are significant health concerns with potential interconnections. However, the underlying mechanisms linking these conditions remain unknown. This study aimed to investigate the potential mediating role of non-steroidal anti-inflammatory drug (NSAID) medication in the association between MDD and the risk of osteomyelitis. METHODS We utilized summary data from large-scale genome-wide association studies (GWAS) to perform Mendelian randomization (MR) mediation analysis. Instrumental variables were selected based on genome-wide significance, and instrumental strength was assessed using F-statistics. Univariable and multivariable MR analyses were conducted to estimate causal effects and proportions mediated by NSAID medication. RESULTS The univariable MR analysis revealed significant associations between MDD and osteomyelitis (odds ratio [OR] = 1.44, 95 % confidence interval [CI]: 1.18-1.874) and between MDD and NSAID medication (OR = 1.36, 95 % CI 1.24-1.49). In the multivariable MR analysis, the direct effect of MDD on osteomyelitis was OR 1.35 (95 % CI: 1.09, 1.67) after adjusting for NSAID medication. The proportion of mediation by NSAID medication was 23 % (95 % CI: 0.05 %, 38.6 %). CONCLUSION This MR study provides evidence for a genetically predicted causal association between MDD, NSAID medication, and osteomyelitis. The findings emphasize the need for a comprehensive approach in managing individuals with comorbid depression and osteomyelitis, considering the potential risks and benefits of NSAID medication. Future research should address limitations and explore additional mediators and confounding factors to enhance understanding of this complex relationship.

Abstract
The revascularization of grafted tissues is a complicated and non-straightforward process, which makes it challenging to perform reconstructive surgery for critical-sized bone defects. This challenge is combined with the low vascularity that results from radiotherapy. This low vascularity could result from ischemia-reperfusion injuries, also known as ischemia which may happen upon grafting. Ischemia may affect the hard tissue during reconstruction, and this can often cause resorption, infections, disfigurement, and malunion. This paper therefore reviews the clinical and experimental application of procedures that were employed to improve the reconstructive surgery process, which would ensure that the vascularity of the tissue is maintained or enhanced. It also presents the key strategies that are implemented to perform tissue engineering within the grafted sites aiming to optimize the microenvironment and to enhance the overall process of neovascularization and angiogenesis. This review reveals that the current strategies, according to the literature, are the seeding of the mature and progenitor cells, use of extracellular matrix (ECM), co-culturing of osteoblasts with the ECM, growth factors and the use of microcapillaries incorporated into the scaffold design. However, due to the unstable and regression-prone capillary structures in bone constructs, further research focusing on creating long-lasting and stable blood vessels is required.

Abstract
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.

Abstract
The opioid epidemic has forced practitioners to look to other means for pain control. This has made non-steroidal anti-inflammatory medications (NSAIDs) much more prevalent. Advantageous as it might seem, a closer look at the pharmacodynamics shows that by inhibiting COX enzymes, NSAIDs are inhibiting prostaglandin which could inhibit bone healing. Our objective is to determine if NSAID use during foot and ankle arthrodesis inhibits bone healing. We reviewed the electronic database of patients who underwent foot and/or ankle arthrodesis with the inclusion criteria of fusion CPT codes. Exclusion was younger than 18 years old, active infection, revisional arthrodesis, less than 3 months follow-up at Phoenix VA Healthcare System, no postoperative radiographs available, and death prior to fusion. One-hundred and sixty-one procedures in 155 patients were included and split into 2 groups. Group 1 included patients without non-union (n = 122) and Group 2, included patients with non-union (n = 39). NSAID use presented in 40 (33%) of procedures in Group 1 compared to 11 (28%) of procedures in Group 2 (Table 2). The mean days on NSAIDs was 51.2 ± 36.1 days in Group 1 compared to 52.2 ± 51.2 days in Group 2 with no statistical difference between groups. Time to fusion was longest in patients on NSAIDs (110 days) or both NSAIDs and active Tobacco use (114 days) and shortest in patients on active Tobacco (93 days) or no NSAIDS and tobacco use (93.61 days). NSAID use did not appear to affect ability to obtain joint fusion, but does appear to delay time to fusion.

Multimodal analgesia is superior to opiates alone after tibial fracture in patients with substance abuse history. OTA Int 2022; 5:e214. [PMID: 36569103 PMCID: PMC9782319 DOI: 10.1097/oi9.0000000000000214] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2021] [Accepted: 05/08/2022] [Indexed: 12/27/2022]
Abstract
Objectives: To evaluate the effectiveness of multimodal analgesia in patients with a tibial shaft fracture. Design: Retrospective review. Setting: Large, urban, academic center. Patients: One hundred thirty-eight patients were evaluated before implementation of multimodal analgesia. Thirty-four patients were evaluated after implementation. All patients were treated operatively with internal fixation for their tibial shaft fracture. Patients with polytrauma were excluded. Intervention: Multimodal analgesia. Main Outcome Measures: Pain levels at rest and with movement were assessed. Morphine milligram equivalents (MMEs) dosed per patient were calculated each day. Length of stay was also documented. Results: After implementation of a multimodal analgesic program, there was a statistically significant decrease in pain score at rest (4.7-4.0, P = 0.034) and with movement (5.8-4.8, P = 0.007). MMEs dosed in the multimodal analgesic program correlated with pain score (R2 = 0.5), whereas before implementation of the program, MMEs dosed were not dependent on pain score (R2 = 0.007). Patients with a history of substance abuse had the most profound effect from this paradigm change. For those with a history of substance abuse, treatment of pain using a multimodal approach reduces MMEs dosed and length of stay (5.7-3.1 days, P = 0.016). Conclusions: Multimodal analgesia improves patient pain scores both at rest and during movement. In patients with a history of substance abuse, multimodal analgesia not only decreases pain but also decreases length of stay and MMEs dosed to levels consistent with someone who does not have a substance abuse history. Level of Evidence: Therapeutic Level III.

Abstract
Fracture healing is highly dependent on an early inflammatory response in which prostaglandin production by cyclo-oxygenases (COX) plays a crucial role. Current patient analgesia regimens favor opioids over Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) since the latter have been implicated in delayed fracture healing. While animal studies broadly support a deleterious role of NSAID treatment to bone-regenerative processes, data for human fracture healing remains contradictory. In this study, we prospectively isolated mouse and human skeletal stem cells (SSCs) from fractures and compared the effect of various NSAIDs on their function. We found that osteochondrogenic differentiation of COX2-expressing mouse SSCs was impaired by NSAID treatment. In contrast, human SSCs (hSSC) downregulated COX2 expression during differentiation and showed impaired osteogenic capacity if COX2 was lentivirally overexpressed. Accordingly, short- and long-term treatment of hSSCs with non-selective and selective COX2 inhibitors did not affect colony forming ability, chondrogenic, and osteogenic differentiation potential in vitro. When hSSCs were transplanted ectopically into NSG mice treated with Indomethacin, graft mineralization was unaltered compared to vehicle injected mice. Thus, our results might contribute to understanding species-specific differences in NSAID sensitivity during fracture healing and support emerging clinical data which conflicts with other earlier observations that NSAID administration for post-operative analgesia for treatment of bone fractures are unsafe for patients.

Abstract
BACKGROUND Femoral shaft fracture is a commonly encountered orthopedic injury that can be treated operatively with a low overall delayed/nonunion rate. In the case of delayed union after antegrade or retrograde intramedullary nail fixation, fracture dynamization is often attempted first. Nonunion after dynamization has been shown to occur due to infection and other aseptic etiologies. We present a unique case of diaphyseal femoral shaft fracture nonunion after dynamization due to intramedullary cortical bone pedestal formation at the distal tip of the nail.
CASE SUMMARY A 37-year-old male experienced a high-energy trauma to his left thigh after coming down hard during a motocross jump. Evaluation was consistent with an isolated, closed, left mid-shaft femur fracture. He was initially managed with reamed antegrade intramedullary nail fixation but had continued thigh pain. Radiographs at four months demonstrated no evidence of fracture union and failure of the distal locking screw, and dynamization by distal locking screw removal was performed. The patient continued to have pain eight months after the initial procedure and 4 mo after dynamization with serial radiographs continuing to demonstrate no evidence of fracture healing. The decision was made to proceed with exchange nailing for aseptic fracture nonunion. During the exchange procedure, an obstruction was encountered at the distal tip of the failed nail and was confirmed on magnified fluoroscopy to be a pedestal of cortical bone in the canal. The obstruction required further distal reaming. A longer and larger diameter exchange nail was placed without difficulty and without a distal locking screw to allow for dynamization at the fracture site. Post-operative radiographs showed proper fracture and hardware alignment. There was subsequently radiographic evidence of callus formation at one year with subsequent fracture consolidation and resolution of thigh pain at eighteen months.
CONCLUSION The risk of fracture nonunion caused by intramedullary bone pedestal formation can be mitigated with the use of maximum length and diameter nails and close follow up.

Abstract
BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly prescribed medications in the United States. Although they are safe and effective means of analgesia for children with broken bones, there is considerable variation in their clinical use due to persistent concerns about their potentially adverse effect on fracture healing.
AIM To assess whether NSAID exposure is a risk factor for fracture nonunion in children.
METHODS We systematically reviewed the literature reporting the effect of NSAIDs on bone healing. We included all clinical studies that reported on adverse bone healing complications in children with respect to NSAID exposure. The outcomes of interest were delayed union or nonunion. Study quality was assessed using the Newcastle-Ottawa scale for non-randomized studies. A final table was constructed summarizing the available evidence.
RESULTS A total of 120 articles were identified and screened, of which 6 articles were included for final review. Nonunion in children is extremely rare; among the studies included, there were 2011 nonunions among 238822 fractures (0.84%). None of the included studies documented an increased risk of nonunion or delayed bone healing in those children who are treated with NSAIDs in the immediate post-injury or peri-operative time period. Additionally, children are likely to take these medications for only a few days after injury or surgery, further decreasing their risk of adverse side-effects.
CONCLUSION This systematic review suggests that NSAIDS can be safely prescribed to pediatric orthopaedic patients absent other contraindications without concern for increased risk of fracture non-union or delayed bone healing. Additional prospective studies are needed focusing on higher risk fractures and elective orthopaedic procedures such as osteotomies and spinal fusion.

How Do Drugs Affect the Skeleton? Implications for Forensic Anthropology. BIOLOGY 2022; 11:biology11040524. [PMID: 35453723 PMCID: PMC9030599 DOI: 10.3390/biology11040524] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 02/21/2022] [Accepted: 03/18/2022] [Indexed: 01/10/2023]
Abstract
Simple Summary Forensic anthropologists analyze human remains to assist in the identification of the deceased, predominantly by assessing age-at-death, sex, stature, ancestry and any unique identifying features. Whilst methods have been established to create this biological profile of the skeleton, these may be influenced by a number of factors. This paper, for the first time, provides an overview from a reading of the clinical and pharmacological literature to explore whether the intake of drugs can affect the skeleton and whether these may have implications for forensic anthropology casework. In effect, drugs such as tobacco, heroin, and prescription medications can alter bone mineral density, can increase the risk of fractures, destroy bone and changes to the dentition. By considering how drugs can affect the skeleton, forensic anthropologists can be aware of this when attempting to identify the deceased. Abstract Forensic anthropologists rely on a number of parameters when analyzing human skeletal remains to assist in the identification of the deceased, predominantly age-at-death, sex, stature, ancestry or population affinity, and any unique identifying features. During the examination of human remains, it is important to be aware that the skeletal features considered when applying anthropological methods may be influenced and modified by a number of factors, and particular to this article, prescription drugs (including medical and non-medical use) and other commonly used drugs. In view of this, this paper aims to review the medical, clinical and pharmacological literature to enable an assessment of those drug groups that as side effects have the potential to have an adverse effect on the skeleton, and explore whether or not they can influence the estimation of age-at-death, sex and other indicators of the biological profile. Moreover, it may be that the observation of certain alterations or inconsistencies in the skeleton may relate to the use of drugs or medication, and this in turn may help narrow down the list of missing persons to which a set of human remains could belong. The information gathered from the clinical and medical literature has been extracted with a forensic anthropological perspective and provides an awareness on how several drugs, such as opioids, cocaine, corticosteroids, non-steroidal anti-inflammatory drugs, alcohol, tobacco and others have notable effects on bone. Through different mechanisms, drugs can alter bone mineral density, causing osteopenia, osteoporosis, increase the risk of fractures, osteonecrosis, and oral changes. Not much has been written on the influence of drugs on the skeleton from the forensic anthropological practitioner perspective; and this review, in spite of its limitations and the requirement of further research, aims to investigate the current knowledge of the possible effects of both prescription and recreational drugs on bones, contributing to providing a better awareness in forensic anthropological practice and assisting in the identification process of the deceased.

Reduction of Opioid Consumption After Outpatient Orthopaedic Trauma Surgeries Using a Multimodal Pain Protocol. J Am Acad Orthop Surg 2022; 30:e327-e335. [PMID: 34723860 DOI: 10.5435/jaaos-d-20-01417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2021] [Accepted: 09/22/2021] [Indexed: 02/01/2023] Open
Abstract
INTRODUCTION Because of the dearth of literature in the orthopaedic trauma population, we aimed to analyze how a multimodal pain protocol after outpatient surgery affects opioid consumption, pain scores, and patient satisfaction. METHODS This was a cohort study with a historical control at an urban level 1 trauma center. Forty consecutive outpatients were given a peripheral nerve block and a multimodal pain protocol between September 2019 and March 2020 and compared with 70 consecutive preprotocol patients who received a peripheral nerve block and hydrocodone-acetaminophen. The primary outcome was morphine milligram equivalents (MMEs) consumed. Our secondary aims were pain scores and satisfaction. RESULTS Patients in the protocol were younger (36.45 versus 45.09 years, P = 0.007), butthere was no difference in sex, body mass index, American Society of Anesthesiologists, or surgical duration. There was a 59% reduction in opioids consumed in the first 4 days after surgery (3.83 MME versus 9.29 MME, P < 0.001). At the postoperative day-14 time point, protocol patients consumed a total of 5.59 MMEs, which is 40% less than just the first 4 days of the preprotocol (P = 0.02). Protocol patients assigned a higher rating of "least pain" on postoperative day 1 (1.24 versus 0.52, P = 0.04) but had higher satisfaction scores on day 1 (9.68 versus 8.54, P < 0.001) and day 2 (9.66 versus 8.61, P < 0.001). CONCLUSION Implementation of a multimodal pain management protocol after outpatient orthopaedic trauma surgeries reduced opioid consumption by >50% in the first 4 days postoperatively. Additional studies are needed to refine the multimodal pain protocol used in this study. LEVEL OF EVIDENCE II.

Abstract
Objective: The purpose of this study was to analyze the risk factors for limb fracture non-union in order to improve non-union prevention and early detection. Methods: A total of 223 patients with non-union after surgery for limb fractures performed at our institution from January 2005 to June 2017 were included as the case group, while a computer-generated random list was created to select 446 patients with successful bone healing after surgery for limb fractures who were treated during the same period as the control group, thus achieving a ratio of 1:2. The medical records of these patients were reviewed retrospectively. Age, sex, body mass index, obesity, smoking, alcohol, diabetes, hypertension, osteoporosis, fracture type, multiple fractures, non-steroidal anti-inflammatory drugs (NSAIDs) use, delayed weight bearing, internal fixation failure, and infection data were analyzed and compared between the two groups. A multivariate logistic regression model was constructed to determine relevant factors associated with non-union. Results: After comparison between two groups by univariate analysis and multivariate logistic regression, we found some risk factors associated that osteoporosis (odds ratio [OR] = 3.16, 95% confidence interval [CI]: 2.05–4.89, p < 0.001), open fracture (OR = 2.71, 95%CI: 1.72–4.27, p < 0.001), NSAIDs use (OR = 2.04, 95%CI: 1.24–3.37, p = 0.005), delayed weight bearing (OR = 1.72, 95%CI: 1.08–2.74, p = 0.023), failed internal fixation (OR = 5.93, 95%CI: 2.85–12.36, p < 0.001), and infection (OR = 6.77, 95%CI: 2.92–15.69, p < 0.001) were independent risk factors for non-union after surgery for limb fractures. Conclusions: Osteoporosis, open fracture type, NSAIDs use, delayed weight bearing, failed internal fixation, and infection were found to be the main causes of bone non-union; clinicians should, therefore, take targeted measures to intervene in high-risk groups early.

Abstract
Purpose Controversy exists regarding the acute effect of non-steroidal anti-inflammatory drugs (NSAIDs) on early fracture healing. The purpose of this study was to analyze the rate of nonunion or delayed union in patients with fifth metatarsal (5th MT) fractures. We hypothesize that the use of NSAIDs would increase the rate of nonunion/delayed union in 5th MT fractures. Methods Using PearlDiver, a national insurance database was analyzed. ICD codes were used to identify patients diagnosed with 5th MT fracture from 2007-2018. Patients were grouped by initial management (nonoperative vs. open reduction and internal fixation (ORIF) or non/malunion repair within 60 days) and sub-grouped by whether they had been prescribed at least one pre-defined NSAID. Subsequent ORIF or nonunion/malunion repair operative intervention was used as a surrogate for fracture nonunion/delayed union. Results Of the 10,991 subjects with a diagnosis of 5th MT, 10,626 (96.7%) underwent initial nonoperative treatment, 1,409 of which (13.3%) received prescription NSAIDS within 60 days of diagnosis. 16/1,409 (1.14%) subjects who received anti-inflammatory prescriptions underwent ORIF or repair of non/malunion at least 60 days after diagnosis while 46/9,217 (0.50%; P=0.003483) subjects who did not receive anti-inflammatory prescriptions underwent ORIF or repair of non/malunion at least 60 days after diagnosis. In the 365 subjects who underwent early repair/ORIF (within 60 days), there was no significant difference in the rate of nonunion/delayed union. Conclusion The rate of nonunion/delayed union of 5th MT fractures was significantly higher in subjects receiving NSAIDs within 60 days of initial diagnosis in patients managed non-operatively.

Abstract
Aims:A controlled release drug delivery system loaded with buprenorphine and ketorolac was synthesized and used in the experimental model of bone defect and while evaluating the inflammatory response, the repair process in the defects was investigated.Materials and methods:To determine the effectiveness of the synthesized the mentioned systems, 5 groups were defined; the control group, the chitosan hydrogel receiving group (chitosan group), the ketorolac-loaded chitosan hydrogel group (ketorolac group), the buprenorphine-loaded chitosan hydrogel receiving group (buprenorphine group), and the chitosan hydrogel-loading group loaded with a combination of ketorolac and buprenorphine (ketorolac-buprenorphine group).Results:The results showed that the population of leukocytes (tWBC) and neutrophils on different days of the study in the control group compared to other groups had a significant increase (P < 0.05) while on day 7 of the study in the ketorolac group these parameters decreased significantly compared to other groups (P < 0.05). While examining the histological changes in the experimental defect created in the proximal tibia of rats at different times, some inflammatory indices such as total and differential leukocyte population, plasma concentrations of TNF-α and IL-6 were compared in different groups (P < 0.05). The various evaluated data showed that among the different groups, in the control and ketorolac-buprenorphine groups, there was the lowest and highest control of inflammatory response and bone repair, respectively.Conclusion:In the ketorolac group due to the impact of ketorolac on leukocyte populations the best bone healing can be expected among the different treatment groups.

Abstract
The human skeleton has remarkable regenerative properties, being one of the few structures in the body that can heal by recreating its normal cellular composition, orientation and mechanical strength. When the healing process of a fractured bone fails owing to inadequate immobilization, failed surgical intervention, insufficient biological response or infection, the outcome after a prolonged period of no healing is defined as non-union. Non-union represents a chronic medical condition not only affecting function but also potentially impacting the individual's psychosocial and economic well-being. This Primer provides the reader with an in-depth understanding of our contemporary knowledge regarding the important features to be considered when faced with non-union. The normal mechanisms involved in bone healing and the factors that disrupt the normal signalling mechanisms are addressed. Epidemiological considerations and advances in the diagnosis and surgical therapy of non-union are highlighted and the need for greater efforts in basic, translational and clinical research are identified.

Abstract
BACKGROUND The use of cannabis is common among athletes and the US population at large. Cannabinoids are currently being evaluated as alternatives to opioid medications for chronic pain management. However, the effects of recreational and/or medical use of delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) on musculoskeletal injury and healing remain largely unknown. HYPOTHESIS/PURPOSE The purpose of this study was to evaluate the biomechanical effects of CBD and THC on tendon-to-tendon healing in a rat Achilles tendon repair model. The hypothesis was that rats administered CBD would demonstrate decreased tensile load to failure of surgically repaired Achilles tendons compared with the THC and control groups. STUDY DESIGN Controlled laboratory study. METHODS A total of 33 Sprague Dawley rats underwent Achilles tendon surgical transection and repair and were randomized to receive subcutaneous injection of THC, CBD, or vehicle once daily starting on the day of surgery and for 5 total days. After sacrifice, biomechanical tensile load-displacement testing was performed to determine Achilles tendon load to failure and stiffness. Data were analyzed by 1-way analysis of variance. RESULTS The THC group demonstrated the highest median load to failure, 18.7 N (95% CI, 15.3-19.2 N); the CBD group had the second highest at 16.9 N (95% CI, 15.1-19.8 N), and the control group had the lowest at 14.4 N (95% CI, 12.1-18.3 N). Stiffness was highest in the THC group at 4.1 N/mm (95% CI, 2.7-5.1 N/mm) compared with 3.6 N/mm (95% CI, 2.9-4.1 N/mm) for the CBD group and 3.6 N/mm (95% CI, 2.8-4.3 N/mm) for the control group. No statistically significant differences for strength and stiffness were observed between the groups. CONCLUSION In this pilot study using an animal tendon-to-tendon repair model, neither THC nor CBD resulted in altered biomechanical characteristics compared to control. CLINICAL RELEVANCE Cannabinoids do not appear to adversely affect Achilles tendon healing.

Abstract
Fracture healing is a complex cascade of cellular and molecular processes. These processes require the appropriate cellular and molecular environment to ensure the restoration of skeletal stability and resolution of inflammation. In order for fracture healing to occur, the necessary building blocks for bone metabolism and synthesis must be supplied through proper nutrition. Pharmacologic therapies aimed at modulating the inflammatory response to fractures have the potential to interfere with the synthesis of molecules needed for the production of bone. Infection can interfere with, and even prevent normal fracture healing from occurring. Cellular and genetic treatment strategies are actively being developed to target deficiencies, and bridge gaps that can influence how fractures heal. Evolving technologies, including nutritional supplementation, pharmacotherapies, antibiotics, surgical techniques, as well as genetic and cellular therapies, have the potential to enhance, optimize, and even revolutionize the process of fracture healing.

Abstract
BACKGROUND There is limited, and often conflicting, data in the literature about the prevalence and risk factors for surgical site infections (SSI) in spine surgery patients, with the majority consisting of elective spine surgery cohorts. Furthermore, there is no reported Australian data regarding rates of SSI in a spinal trauma cohort. The aim of this study is to identify factors associated with SSI following spinal column trauma. METHODS Adult (16+ years) patients that underwent surgery following emergency admission for spinal trauma between January 2010 and December 2016 at a major trauma centre in Melbourne, Australia, were identified through the Victorian Orthopaedic Trauma Outcomes Registry. The presence of an SSI was confirmed from the electronic medical record. Patient and clinical factors were analysed by SSI status. Generalized Estimating Equations were used to model predictors of SSI, with a P-value <0.05 deemed significant. RESULTS Data for 458 patients and 520 surgical wounds were collected. Twenty-six (5.7%) patients developed an SSI. Staphylococcus aureus was the most common microorganism with methicillin-sensitive S. aureus found in 46% of SSI cases. A posterior surgical approach and same site reoperation were predictors of SSI with adjusted odds ratios (95% confidence intervals) of 4.26 (1.22-14.80, P = 0.02) and 4.99 (1.10-22.58, P = 0.04), respectively. CONCLUSIONS A posterior surgical approach and same site reoperation increased the risk of SSI after spinal trauma. Further research into modifiable associations within these and other factors will help mitigate the risk of SSI and hence decrease the personal and financial costs of this potentially devastating complication.

Abstract
Achieving bone fracture union after trauma represents a major challenge for the orthopedic surgeon. Fracture non-healing has a multifactorial etiology and there are many risk factors for non-fusion. Environmental factors such as wound contamination, infection, and open fractures can contribute to non-healing, as can patient specific factors such as poor vascular status and improper immunologic response to fracture. Nitric oxide (NO) is a small, neutral, hydrophobic, highly reactive free radical that can diffuse across local cell membranes and exert paracrine functions in the vascular wall. This molecule plays a role in many biologic pathways, and participates in wound healing through decontamination, mediating inflammation, angiogenesis, and tissue remodeling. Additionally, NO is thought to play a role in fighting wound infection by mitigating growth of both Gram negative and Gram positive pathogens. Herein, we discuss recent developments in NO delivery mechanisms and potential implications for patients with bone fractures. NO donors are functional groups that store and release NO, independent of the enzymatic actions of NOS. Donor molecules include organic nitrates/nitrites, metal-NO complexes, and low molecular weight NO donors such as NONOates. Numerous advancements have also been made in developing mechanisms for localized nanomaterial delivery of nitric oxide to bone. NO-releasing aerogels, sol- gel derived nanomaterials, dendrimers, NO-releasing micelles, and core cross linked star (CCS) polymers are all discussed as potential avenues of NO delivery to bone. As a further target for improved fracture healing, 3d bone scaffolds have been developed to include potential for nanoparticulated NO release. These advancements are discussed in detail, and their potential therapeutic advantages are explored. This review aims to provide valuable insight for translational researchers who wish to improve the armamentarium of the feature trauma surgeon through use of NO mediated augmentation of bone healing.

Abstract
In this article, we review controversies in assessing the risk of serious adverse effects caused by administration of nonsteroidal anti-inflammatory drugs (NSAIDs). Our focus is upon NSAIDs used in short courses for the management of acute postoperative pain. In our review of the literature, we found that the risks of short-term NSAID use may be overemphasized. Specifically, that the likelihood of renal dysfunction, bleeding, nonunion of bone, gastric complications, and finally, cardiac dysfunction do not appear to be significantly increased when NSAIDs are used appropriately after surgery. The importance of this finding is that in light of the opioid epidemic, it is crucial to be aware of alternative analgesic options that are safe for postoperative pain control.

The Impact of Nonsteroidal Anti-inflammatory Drugs on Older Adult Trauma Patients With Hip Fractures. J Surg Res 2020; 255:583-593. [PMID: 32650142 DOI: 10.1016/j.jss.2020.05.064] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2020] [Revised: 04/03/2020] [Accepted: 05/05/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND Nonsteroidal anti-inflammatory drug (NSAID) use is frequently recommended for multimodal analgesia to reduce opioid use. We hypothesized that increased NSAID utilization will decrease opioid requirements without leading to significant complications in older adult trauma patients undergoing hip fracture repair. METHODS An observational cross-sectional cohort study of 190,057 adult trauma patients over a 6-y period (2008-2014) in the national Premier Healthcare Database was performed. Patients aged 65 or older undergoing femur repair and hip arthroplasty following fractures due to falls were analyzed. Primary outcome was opioid use, and secondary outcomes included transfusion requirements, length of stay (LOS), and organ system dysfunction. Continuous outcomes were analyzed using mixed-effect linear regression models to assess the effect of NSAIDs on the day of surgery. Fixed effects were included for patient and hospital characteristics, comorbidities, co-treatments, and surgery. Random intercepts for each hospital were included to control for clustering. Categorical outcomes were similarly analyzed using mixed-effect logistic regression models. RESULTS NSAIDs decreased opioids prescribed (12.01 versus 11.43 morphine milligram equivalents) (odds ratio [OR], -0.23; confidence interval [CI] = -0.41, -0.06) without overall increased bleeding (40.83% versus 43.18%; OR, 1.02; CI = 0.99, 1.05). NSAIDs were associated with reduced LOS (5.61 versus 5.96 d; CI = -0.24, -0.12), intensive care unit admissions (9.73% versus 10.59%; OR, 0.91; CI = 0.86, 0.96), and pulmonary complications (OR, 0.88; CI = 0.83, 0.93). Additionally, there was a 21% prescribing variability based solely on hospital. CONCLUSIONS NSAIDs were associated with decreased opioid requirements, hospital LOS, and intensive care unit admissions in older adult trauma patients without overall increase in bleeding. NSAIDs should be considered in multimodal pain regimens, moreover, given prescribing variability guidelines are needed. LEVEL OF EVIDENCE Level III, Prognostic.

Abstract
The association of nonsteroidal anti-inflammatory drugs (NSAIDs) with non-union in long bone fractures has been controversial. The purpose of this study was to evaluate whether NSAID exposure results in increased risk of non-union in operatively treated long bone fractures. The authors used International Classification of Diseases and Current Procedural Terminology codes to identify patients under a single-payer private insurance with operatively treated humeral shaft, tibial shaft, and subtrochanteric femur fractures from a large database. Patients were divided into cohorts based on NSAID use in the immediate postoperative period, and nonunion rates were compared. A cost analysis and a multivariate analysis were performed. Between 2007 and 2016, a total of 5310 tibial shaft, 3947 humeral shaft, and 8432 subtrochanteric femur fractures underwent operative fixation. Patients used NSAIDs in the first 90 days postoperatively in 900 tibial shaft, 694 humeral shaft, and 967 subtrochanteric femur fractures. In these patients, nonunion rates were 18.8%, 17.4%, and 10.4%, respectively. When no NSAIDs were used, the rates were 11.4%, 10.1%, and 4.6% for each fracture type, respectively (P<.05). Among patients taking NSAIDs, subtrochanteric femur fractures had a 2.4 times higher risk of nonunion and humeral shaft and tibial shaft fractures both had a 1.7 times higher risk of nonunion (P<.05). Multivariate analysis showed NSAID use to be an independent risk factor in all 3 types. Cost analysis showed a great increase in economic burden (P<.05). This study indicated that NSAID exposure was associated with fracture nonunion. [Orthopedics. 2020;43(4):221-227.].

Abstract
AIM Evaluate the frequency, nature and course of PTP, as well as the effectiveness and safety of NSAIDs in PTP in real clinical practice. MATERIALS AND METHODS The assessment of the condition and need for NSAIDs (original meloxicam) in 1115 outpatient patients who suffered a fracture of the radius (32.2%), injury to the knee (35.2%) or ligaments of the ankle (32.6%); women/men 51.5 and 48.5%, average age 46.915.5 years. We evaluated the dynamics of pain intensity (on a numerical rating scale NRS 010) at rest and during movement, the preservation of moderate and severe pain, as well as the development of adverse drugs reactions (ADR) to NSAIDs 48 weeks after injury. RESULTS The average intensity of pain during movement decreased from 7.031.66 to 2.211.38 (p0.001), at rest from 4.462.07 to 0.710.989 (p0.001). The number of people with pain severity 4 in the NRS in 48 weeks after the radius fracture, injury of the knee and ligaments of ankle was 21.0, 16.9 and 11.9%, with moderate or severe impairment of the injured limb 40.4, 26.2 and 16.3%, respectively. The need for taking NSAIDs up to 7 days was noted in 43.3%, 714 days-in 41.8%, more than 2 weeks or constantly in 14.9% of patients. Weak or moderate ADR were observed in 20.8% of patients, mainly dyspepsia and hypertension. Discontinuation of NSAIDs due to ADR was required in only 2.6% of patients. Pain retention 4 in NRS was associated with initially expressed pain (7 in NRS) OR 2.75 (95% CI 0.834.13; p0.001) and the presence of osteoarthritis of knee and/or hip OR 1.56 (95% CI 1.032.34; p=0.039). CONCLUSION PTP decreases rapidly in most patients after a radius fracture, injury of the knee, and ankle ligament injury while taking the original meloxicam. However, in a significant part of patients, moderate or severe PTP persists after 48 weeks, which requires prolonged analgesic therapy and active rehabilitation.

Abstract
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.

Abstract
When treating pain in the orthopaedic trauma patient opioids have classically represented the mainstay of treatment. They are relatively inexpensive and modestly effective for basic pain management. However, they are fraught with considerable side effects as well as the very high risk of addiction. Their use in pain management has been implicated in the opioid epidemic. For this reason, as well as their only moderate efficacy, alternative modes of treatment have been sought for both the patient with isolated limb trauma and the patient with poly trauma. We review alternative treatment methods in pain management for those with isolated limb trauma and poly trauma. These methods include topical agents, as well as non steroidal anti-inflammatory medications, acetaminophen, gabapetoids, intravenous agents, varying degrees of local anesthetic infiltration and peripheral nerve blocks, and the newer modality of fascial plane blocks. Often, it is a combination of these analgesic modalities that gives the most optimum treatment for the trauma patient. This also, more frequently than not, must be individually tailored to the patient, as no two patients act the same in this regard. It is therefore of importance that the physician managing such patients's pain be experienced and well-versed in all these treatment modalities. We also provide a basic stepwise algorithm we have found useful in treating those with single extremity or single site trauma versus those patients with poly trauma and resultant multiple sources as pain generators. It is hoped that this breakdown of the different modalities along with a better understanding of each modality's potential benefits and indications will aid the surgeon in providing better care to patients following orthopedic trauma.

Corrective osteotomies of femur and tibia: which factors influence bone healing? Arch Orthop Trauma Surg 2020; 140:303-311.

Abstract
INTRODUCTION Corrective osteotomies of the lower limb are standard procedures in orthopedic surgery. Still, there is only limited research on factors affecting bone healing after osteotomies. We hypothesize that especially the location of the osteotomy, smoking status and BMI affect bone healing. MATERIAL AND METHODS The healing process of 547 patients who underwent osteotomies of the lower limb (259 female, 288 male; average 40.6 years, range 14-77) was evaluated. To assess bone healing, participants were divided into three groups by bone healing duration ( < 5/5-8/ > 8 months). Differences in healing duration related to the anatomic level of the osteotomy (diaphysis vs. metaphysis), age, gender, smoking status, BMI, and modus of the osteotomy (open vs. closed wedge) were tested for significance using an ordinal regression analysis. RESULTS A significant correlation between bone healing and the anatomical level of the osteotomy on femur and tibia and the patients' smoking status was found. The odds of the diaphysis considering bone healing was 0.187 (95% CI, 0.08-0.44) times that of the metaphysis (Wald χ2(1) = 14.597, p < 0.000). The odds ratio of smokers considering bone healing was 0.192 (95% CI, 0.11-0.33) times that of non-smokers (Wald χ2(1) = 35.420, p < 0.000). All other analyzed factors did not show a significant correlation with bone healing. CONCLUSIONS Smoking status and the localization of the osteotomy on femur and tibia (diaphysis vs. metaphysis) are significantly correlated with bone healing duration. In line with current literature emphasizing the detrimental effect of smoking on bone healing, our findings should encourage surgeons to think twice about the indication to perform osteotomies on smokers. Furthermore, if applicable, osteotomies should be performed in the metaphyseal areas of femur and tibia.

Abstract
BACKGROUND The investigation of nonnarcotic drug regimens for postoperative pain management is important in addressing the opioid epidemic. NSAIDs can be a powerful adjunct in managing postoperative pain, but the possibility of delayed bone healing is a major concern for orthopaedic surgeons. Our recent retrospective study on ketorolac administration demonstrated that the NSAID is not associated with an increased risk of delayed union or nonunion after ankle fracture surgery. QUESTIONS/PURPOSES To determine whether postoperative ketorolac (1) reduces opioid consumption, (2) improves VAS pain control, and (3) affects fracture healing after open reduction and internal fixation of ankle fractures. METHODS Between August 2016 and December 2017, 128 patients undergoing open reduction and internal fixation of an acute ankle fracture were randomized before surgery via simple randomization to treatment with or without ketorolac. No patients changed treatment regimen groups or opted out of randomization. All other aspects of perioperative care were treated identically. A once-daily survey was distributed via email on postoperative Days 1 to 7. Unblinded participants were asked to report their daily opioid consumption, pain level, and sleep interference using the VAS, and pain frequency using a five-point Likert scale, and side effects with the VAS. For VAS pain, > 20 mm/100 mm on the VAS scale was required to be considered "improved." In all, 83% (106 of 128) patients completed all seven postoperative surveys with 14 in the control group and eight in the ketorolac group lost to follow-up. Fifty-six patients were administered ketorolac with opioid medication (treatment group) and 50 were administered opioids alone (control group). Participants were comprised of 42% men (44), and 58% women (62); mean age was 48 years. The treating surgeon assessed clinical healing based on the patient's ability to ambulate comfortably at 12 weeks postoperatively. Radiographic healing was assessed by two fellowship-trained orthopaedic foot and ankle surgeons blinded to the patient's name and time since surgery. The surgeons evaluated randomized standard ankle series (anteroposterior, mortise, and lateral) radiographs for resolution of each fracture line to determine fracture union, with delayed union being defined as fracture lines present on radiographs taken at 12-week postoperative visits. Intention-to-treat analysis was performed. RESULTS Patients in the treatment group consumed a mean of 14 opioid pills, which was less than the mean of 19.3 opioids pills consumed by patients in the control group (p = 0.037). Patients with ketorolac had lower median VAS scores for pain (p < 0.035) postoperatively on postoperative Days 1 and 2 than did control patients. By contrast, patient-reported pain scores and scores for sleep did not convincingly show a benefit to the use of ketorolac. For patients whose ankle fractures healed at 12 weeks, there was no difference between the groups in terms of clinical healing (p = 0.575) and radiographic healing (p = 0.961). CONCLUSIONS In this randomized study, adding ketorolac to the postoperative drug regimen decreased the use of opioid medication after open reduction and internal fixation of ankle fractures in the early postoperative period, and there were mixed, small effects on pain reduction. This NSAID is a valuable tool in helping patients manage postoperative pain with less use of narcotic analgesia. However, our study was underpowered to determine the true safety of this drug in terms of fracture healing and side effects and these questions warrant higher-powered randomized study investigation.

Abstract
Introduction This meta-analysis aims to determine whether non-steroidal anti-inflammatory drug (NSAID) use is significantly associated with adverse bone healing outcomes within clinical settings, including trauma and elective spine settings. It will also explore bone healing outcomes with the type, route, dosage and duration of NSAID exposure and aims to demonstrate the effects of various other confounding factors on bone healing outcomes. Methods Electronic databases including MedLine, Embase and Cochrane were searched from January 1975 to December 2017. A distinct analysis of observational long bone and spine studies in adult populations was performed, assessing the effects of NSAID exposure on bone healing. Studies from paediatric population and randomised trials also underwent separate assessment in the synthesis. Meta-analysis was conducted in compliance with QUORUM and PRISMA guidelines. Results Quantitative assessment of observational studies suggested a significant risk of bone healing complications with NSAID exposure across each clinical group: long bone (p = 0.0004) and spine (p = 0.02). Analysis of paediatric studies revealed a non-significant association of poor outcomes with NSAID use (p = 0.36), while assessment of randomised trials demonstrated a statistically significant risk of complications following NSAID administration (p = 0.04). Meta-regression further suggested smoking to be a substantial confounder associated with adverse bone healing outcomes (p < 0.00001). Conclusion Inclusion of only fair and moderate-quality retrospective cohort and case–control studies in the current synthesis limits the clinical application of its findings and therefore warrants the need for further research. Thus, attempts to conduct high-quality prospective cohort and randomised trials to study the effects of NSAID use on bone healing would be very helpful and will provide a basis for more extensive research in future.

Abstract
BACKGROUND Treatment of atrophic non-unions and large bone defects or infections remains a challenging task for the treating surgeon. In the herein study, we present our experience of the 'Masquelet technique' according to the 'diamond concept' for the treatment of complex long bone reconstruction procedures. METHODS Between February 2010 and March 2015, 150 patients (mean age 51.4) with atrophic and- /or infected non-unions were included in this prospective study. All patients received autologous bone graft, a graft expander (TCP (tricalcium phosphate)) and BMP (bone morphogenic protein). Clinical and radiological parameters were assessed at 6 weeks, and at 3, 6 and 12 months. The SF-12 questionnaire was used to evaluate the subjective health of patients. RESULTS A successful bony consolidation of the non-unions was observed in 120 (80%) cases with a median healing time of 12.1 months. The mean defect gap was 4.4cm. Initial infection was documented in 54 cases. The most frequently identified pathogen was staphylococcus epidermidis and staphylococcus aureus. A successful removal of microorganisms with subsequent healing was achieved in 39 cases (72%). The SF-12 scores of subjective physical and mental health increased from PCS 31.5 preoperatively to 36.7 one year postoperatively, while MCS increased from 45.5 to 48.7. CONCLUSIONS Our study showed that the Masquelet technique according to the 'diamond concept' is a valid method to treat complex atrophic non-unions with large bone defects and associated infection. Following the principles of the 'diamond concept' (targeted optimization of tissue engineering and bone regeneration) a high rate of success can be expected in these difficult reconstruction cases.

Abstract
Multiple factors impact fracture healing; thus, endocrine optimization and nutritional optimization warrant investigation in the acute fracture and nonunion patient. This article presents current evidence regarding the role of the endocrinologists and the dietician in the fracture patient as well as the most recent data assessing the vitamin D axis in these populations. Similarly, the most recent information regarding the use and risks of NSAIDs in fracture healing are presented. The fracture surgeon must consider each individual patient and weigh the benefits versus the costs of host optimization.

Abstract
Enhanced recovery after surgery (ERAS) protocols represent patient-centered, evidence-based, multidisciplinary care of the surgical patient. Although these patterns have been validated in numerous surgical specialities, ERAS has not been widely described for patients undergoing hip fracture (HFx) repair. As part of the Agency for Healthcare Research and Quality Safety Program for Improving Surgical Care and Recovery, we have conducted a full evidence review of interventions that form the basis of the anesthesia components of the ERAS HFx pathway. A literature search was performed for each protocol component, and the highest levels of evidence available were selected for review. Anesthesiology components of care were identified and evaluated across the perioperative continuum. For the preoperative phase, the use of regional analgesia and nonopioid multimodal analgesic agents is suggested. For the intraoperative phase, a standardized anesthetic with postoperative nausea and vomiting prophylaxis is suggested. For the postoperative phase, a multimodal (primarily nonopioid) analgesic regimen is suggested. A summary of the best available evidence and recommendations for inclusion in ERAS protocols for HFx repair are provided.

Abstract
PURPOSE We aimed to produce comprehensive guidelines and recommendations that can be utilized by orthopaedic practices as well as other specialties to improve the management of acute pain following musculoskeletal injury. METHODS A panel of 15 members with expertise in orthopaedic trauma, pain management, or both was convened to review the literature and develop recommendations on acute musculoskeletal pain management. The methods described by the Grading of Recommendations Assessment, Development, and Evaluation Working Group were applied to each recommendation. The guideline was submitted to the Orthopaedic Trauma Association (OTA) for review and was approved on October 16, 2018. RESULTS We present evidence-based best practice recommendations and pain medication recommendations with the hope that they can be utilized by orthopaedic practices as well as other specialties to improve the management of acute pain following musculoskeletal injury. Recommendations are presented regarding pain management, cognitive strategies, physical strategies, strategies for patients on long term opioids at presentation, and system implementation strategies. We recommend the use of multimodal analgesia, prescribing the lowest effective immediate-release opioid for the shortest period possible, and considering regional anesthesia. We also recommend connecting patients to psychosocial interventions as indicated and considering anxiety reduction strategies such as aromatherapy. Finally, we also recommend physical strategies including ice, elevation, and transcutaneous electrical stimulation. Prescribing for patients on long term opioids at presentation should be limited to one prescriber. Both pain and sedation should be assessed regularly for inpatients with short, validated tools. Finally, the group supports querying the relevant regional and state prescription drug monitoring program, development of clinical decision support, opioid education efforts for prescribers and patients, and implementing a department or organization pain medication prescribing strategy or policy. CONCLUSIONS Balancing comfort and patient safety following acute musculoskeletal injury is possible when utilizing a true multimodal approach including cognitive, physical, and pharmaceutical strategies. In this guideline, we attempt to provide practical, evidence-based guidance for clinicians in both the operative and non-operative settings to address acute pain from musculoskeletal injury. We also organized and graded the evidence to both support recommendations and identify gap areas for future research.

Abstract
Fracture healing is a complex and integrated process that involves mesenchymal progenitor cell (MPC) recruitment, proliferation and differentiation that eventually results in bone regeneration. Prostaglandin E2 (PGE2) is an important regulator of bone metabolism and has an anabolic effect on fracture healing. Prior work from our laboratory showed EP1-/- mice have enhanced fracture healing, stronger cortical bones, higher trabecular bone volume and increased in vivo bone formation. We also showed that bone marrow MSCs from EP1-/- mice exhibit increased osteoblastic differentiation in vitro. In this study we investigate the changes in the periosteal derived MPCs (PDMPCs), which are crucial for fracture repair, upon EP1 deletion. EP1-/- PDMPCs exhibit increased numbers of total (CFU-F) and osteoblastic colonies (CFU-O) as well as enhanced osteoblastic and chondrogenic differentiation. Moreover, we tested the possible therapeutic application of a specific EP1 receptor antagonist to accelerate fracture repair. Our findings showed that EP1 antagonist administration to wild type mice in the early stages of repair similarly resulted in enhanced CFU-F, CFU-O, and osteoblast differentiation in PDMPCs and resulted in enhanced fracture callus formation at 10 days post fracture and increased bone volume and improved biomechanical healing of femur fractures at 21 days post fracture.

Abstract
INTRODUCTION NSAIDs inhibit osteogenesis and may result in delayed union or nonunion. The purpose of this meta-analysis was to determine whether their use leads to delayed union or nonunion. METHODS We systematically reviewed the literature reporting the effect of NSAIDs on bone healing. We included studies of pediatric and adult patients NSAID exposure and healing bone. The outcomes of interest were delayed union, nonunion, or pseudarthrosis with at least six months of follow-up. A maximum likelihood random-effects model was used to conduct meta-analysis and meta-regression. RESULTS NSAID exposure increased delayed union or nonunion (odds ratio [OR], 2.07; confidence interval [CI], 1.19 to 3.61). No effect was noted in pediatrics (OR, 0.58; CI, 0.27 to 1.21) or low dose/short duration of exposure (OR, 1.68; CI, 0.63 to 4.46). CONCLUSION Analysis of the literature indicates a negative effect of NSAIDs on bone healing. In pediatric patients, NSAIDs did not have a significant effect. The effect may be dose or time dependent because low-dose/short-duration exposure did not affect union rates.

Abstract
Stress fractures are common in military personnel and endurance athletes, and nonsteroidal anti-inflammatory drug (NSAID) use is widespread in these populations. NSAIDs inhibit prostaglandin synthesis, which blunts the anabolic response of bone to physical activity and could therefore increase risk of stress fracture. The objective of this study was to determine whether prescribed NSAIDs were associated with stress fracture diagnoses among US Army soldiers. We also aimed to establish whether acetaminophen, an analgesic alternative to NSAIDs, was associated with stress fracture risk. A nested case-control study was conducted using data from the Total Army Injury and Health Outcomes Database from 2002 to 2011 (n = 1,260,168). We identified soldiers with a diagnosis of stress fracture (n = 24,146) and selected 4 controls per case matched on length of military service (n = 96,584). We identified NSAID and acetaminophen prescriptions 180 to 30 days before injury (or match date). We also identified soldiers who participated in basic combat training (BCT), a 10-week period of heightened physical activity at the onset of Army service. Among these individuals, we identified 9088 cases and 36,878 matched controls. Conditional logistic regression was used to calculate incident rate ratios (RR) for stress fracture with adjustment for sex. NSAID prescription was associated with a 2.9-fold increase (RR = 2.9, 95% confidence interval [CI] 2.8-2.9) and acetaminophen prescription with a 2.1-fold increase (RR = 2.1, 95% CI 2.0-2.2) in stress fracture risk within the total Army population. The risk was more than 5-fold greater in soldiers prescribed NSAIDs (RR = 5.3, 95% CI 4.9-5.7) and more than 4-fold greater in soldiers prescribed acetaminophen (RR = 4.4, 95% CI 3.9-4.9) during BCT. Our results reveal an association between NSAID and acetaminophen prescriptions and stress fracture risk, particularly during periods of heightened physical activity. Prospective observational studies and randomized controlled trials are needed to support these findings before clinical recommendations can be made. © 2018 American Society for Bone and Mineral Research.

Abstract
Background Fusidic acid (FA) (WU-FA-00) is the only commercially available antimicrobial from the fusidane family that has a narrow spectrum of activity against Gram-positive bacteria. Methods Herein, the hydrogenation derivative (WU-FA-01) of FA was prepared and both compounds were examined against a panel of six bacterial strains. In addition, their anti-inflammatory properties were evaluated using a 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced mouse ear edema model. Results The results of the antimicrobial assay revealed that both WU-FA-00 and WU-FA-01 displayed a high level of antimicrobial activity against Gram-positive strains. Moreover, killing kinetic studies were performed and the results were in accordance with the minimum inhibitory concentration and minimum bactericidal concentration results. We also demonstrated that the topical application of WU-FA-00 and WU-FA-01 effectively decreased TPA-induced ear edema in a dose-dependent manner. This inhibitory effect was associated with the inhibition of TPA-induced upregulation of proinflammatory cytokines IL-1β, TNF-α, and COX-2. WU-FA-01 significantly suppressed the expression levels of p65, IκB-α, and p-IκB-α in the TPA-induced mouse ear model. Conclusion Overall, our results showed that WU-FA-00 and WU-FA-01 not only had effective antimicrobial activities in vitro, especially to the Gram-positive bacteria, but also possessed strong anti-inflammatory effects in vivo. These results provide a scientific basis for developing FA derivatives as antimicrobial and anti-inflammatory agents.

Abstract
BACKGROUND In an effort to minimize narcotic analgesia and its potential side effects, anti-inflammatory agents offer great potential provided they do not interfere with bone healing. The safety of ketorolac administration after foot and ankle surgery has not been well defined in the current literature. The purpose of this study was to report clinical healing and radiographic outcomes for patients treated with a perioperative ketorolac regimen after open reduction and internal fixation (ORIF) of ankle fractures. METHODS A retrospective review was performed on all patients that received perioperative ketorolac at the time of lateral malleolar, bimalleolar, and trimalleolar ankle ORIF by a single surgeon between 2010 and 2016 with minimum 4 months follow-up. Patients received 20 tablets of 10 mg ketorolac Q6 hours. Radiographs were evaluated independently by 2 blinded fellowship-trained orthopedic foot and ankle surgeons to assess for radiographic healing. A total of 281 patients were included, with a median age of 51 years and 138 males (47%). Statistical analysis consisted of a linear mixed-effects regression. RESULTS In all, 265/281 (94%) were clinically healed within 12 weeks and 261/281 (92%) were radiographically healed within 12 weeks. Within the group of patients that did not heal within 12 weeks, mean time to clinical healing was 16.9 weeks (range = 14-25 weeks), and mean time to radiographic healing was 17.1 weeks (range = 14-25 weeks). In patients taking ketorolac, there were no cases of nonunion in our series (n = 281) and no significant difference found between fracture patterns and healing or complications ( P = .500). CONCLUSIONS Perioperative ketorolac use was associated with a high rate of fracture union by 12 weeks. This is the first study to examine the effect of ketorolac on radiographic time to union of ankle fractures. Additional studies are necessary to determine whether ketorolac helps reduce opioid consumption and improve pain following ORIF of ankle fractures. LEVEL OF EVIDENCE Level IV, case series.

Effect of non-steroidal anti-inflammatory drugs on post-surgical complications against the backdrop of the opioid crisis. BURNS & TRAUMA 2018; 6:25.

Abstract
The USA is currently going through an opioid crisis, associated with tremendous economic and societal impacts. In response to this crisis, healthcare professionals are looking for alternative pain management methods, and non-steroidal anti-inflammatory drugs (NSAIDs) are a sensible choice because of their effectiveness after surgical procedures. However, before surgeons start prescribing NSAIDs in place of opioids, it is crucial to first understand their potential post-surgical complications. The goal of this review is to summarize the data obtained through both animal and human studies, which suggest how a dramatic increase in NSAID use may affect these post-surgical complications. We first provide a short review outlining the mechanisms of action of NSAIDs, followed by a summary of animal studies, which show a trend towards the negative effects of NSAIDs on wound healing and an association between NSAID use and wound infections. Lastly, we present evidence from human studies on the association of NSAIDs with the following complications: anastomotic leaks, necrotizing soft tissue infections, bleeding complications, orthopedic injuries, wound healing, and cancer care. The human studies are much more variable in their conclusions as to whether NSAIDs are beneficial or not, with the only strong evidence showing that NSAIDs inhibit bone healing. This may partially be explained by male and female differences in response to NSAIDs as many animal studies showing the inhibitory effects of NSAIDs were performed on females, while all the human studies were performed with both sexes. We conclude that strong caution should be used in the prescription of NSAIDs, especially in female patients, but larger scale studies are warranted before solid recommendations can be made.

Abstract
Bone tissue undergoes constant remodeling and healing when fracture happens, in order to ensure its structural integrity. In order to better understand open biological and clinical questions linked to various bone diseases, bone cell co-culture technology is believed to shed some light into the dark. Osteoblasts/osteocytes and osteoclasts dominate the metabolism of bone by a multitude of connections. Therefore, it is widely accepted that a constant improvement of co-culture models with both cell types cultured on a 3D scaffold, is aimed to mimic an in vivo environment as closely as possible. Although in recent years a considerable knowledge of bone co-culture models has been accumulated, there are still many open questions. We here try to summarize the actual knowledge and address open questions.

Injury 2018; 49:1266-1271.

Abstract
INTRODUCTION Certain common medications are associated with an elevated risk of fracture and recent data suggests that medications can also increase nonunion risk. Medication use is a modifiable nonunion risk factor, but it is unknown whether risk accrues solely to chronic medication use or whether there is also risk inherent to acute use. METHODS Multivariate logistic regression was used in an inception cohort to calculate odds ratios (OR) for fracture nonunion associated with medication use, in context with other risk factors demonstrated to influence nonunion. Patient-level health claims for medical and drug expenses were compiled from a payer database. Patients were included if they had a fracture coded in 2011, with continuous enrollment for 1 month prior to and 12 months after fracture. The database contained demographic descriptors, treatment procedures per CPT codes, co-morbidities per ICD-9 codes, and prescriptions per National Drug Codes. Chronic medication use was defined as ≥30 days of prescription prior to fracture with ≥1 day afterward; acute use was any other prescription. RESULTS Most non-analgesic medications were safe in acute or chronic use, but risk of nonunion was elevated for a wide range of analgesics. Overall, 45,085 fractures (14.6% of fractures) affected patients using chronic opioids. Nonunion OR was elevated for acute and chronic use of Schedule 2 opioids including acetaminophen/oxycodone, hydromorphone, oxycodone, and acetaminophen/hydrocodone bitartrate, as well as Schedule 3-5 opioids including tramadol (all, p < 0.0001). The highest ORs were associated with chronic administration of Schedule 2 opioids. DISCUSSION Most medications do not increase nonunion risk, but acute and chronic use of NSAIDs or opioids was associated with impaired fracture healing. There is particular risk in prescribing opioid analgesics for fracture, though literature suggests that roughly half of opioid-naïve patients receive such a prescription. CONCLUSIONS Patients evaluated in this study were not a random sample of Americans; they may approximate a random sample of the Emergency Department population in the United States. Thus, trauma patients may represent a population enriched for nonunion risk factors. Opioids impair recovery from injury; if they also predispose to injury, the ongoing opioid epidemic could presage an increase in nonunion prevalence.

Abstract
Tissue damage following injury triggers the processes of coagulation, inflammation and healing. In tissues surrounding the bone, the result of the healing process is a scar, while bone tissue has a unique ability to achieve shape, strength and pre-injury function. Bone healing is a process of regeneration rather than classic recovery. The result of this process is the formation of new, healthy bone tissue instead of a scar. Many factors can inhibit or impair the bone healing process, and their influence is critical during the stages of inflammation and angiogenesis and finally on the clinical outcome. Nonsteroidal anti-inflammatory drugs (NSAIDs) play an essential role associated with their analgesic potency and anti-inflammatory effects. NSAIDs are also the most often used drugs in patients who require pain control and inflammation reduction due to musculoskeletal diseases or injures. Although their analgesic effect is well documented, NSAIDs also interfere with bone healing; therefore, the relative benefits and disadvantages connected with their administration should be taken into consideration. Despite the negative effect, NSAIDs have beneficial properties, but their clinical benefits in relation to dose and time of use are still unclear. Therefore, in this review, we focus on bone healing with relation to the impact of NSAIDs.

Abstract
UNLABELLED Background Orthopedic surgeons frequently prescribe pain medications during the postoperative period. The efficacy of these medications at alleviating pain after foot/ankle surgery and the quantity of medication required (and conversely, leftover) are unknown. METHODS Patients undergoing foot/ankle surgery during a 3-month period who met inclusion criteria were surveyed at their first postoperative visit. Information collected included gender, number of prescribed pills remaining, satisfaction with pain control, and willingness to surrender leftover opioids to a Drug Enforcement Administration (DEA) disposal center. Additional data, including utilization of a perioperative nerve block and type (bony versus nonbony) and anatomic region of procedure, were collected through review of the medical record. All data were analyzed in a retrospective fashion. A total of 171 patients with a mean age of 53.1 ± 15.5 years (range, 18-81 years) were included in the study. RESULTS The mean number of opioids taken was 27.2 ± 17.5 pills (range, 0-70). The mean number of short-acting opioids and long-acting opioids taken was 21.4 ± 14.8 and 9.2 ± 5.0 pills, respectively. Most (73.5%) patients were satisfied with their pain control. Patients who underwent ankle/hindfoot surgery took more long-acting opioids on average than others ( P = .047). There was not a significant difference in opioid usage between bony and nonbony procedures. Of those with leftover opioids, 63% were willing to surrender them to a DEA disposal center. Patients willing to surrender leftover medications had both more short-acting ( P < .001) and long-acting ( P = .015) opioids leftover than those not willing to surrender them. CONCLUSION Most patients undergoing foot/ankle surgery had opioids leftover at the first postoperative visit, and most were willing to surrender them. We can adequately treat patients' pain and decrease the number of opioid pills available in the community by decreasing the number of pills prescribed and encouraging disposal of leftovers. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
STUDY DESIGN Clinical commentary. INTRODUCTION Proximal humeral fractures (PHF) are the third most common fracture in the elderly with an increased incidence expected in the coming years with the aging population, causing an important burden to the healthcare system. The management of PHF is challenging due to its complexity and the wide variety of fractures and treatment options. PURPOSE The objective of this clinical commentary is to update the available evidence on clinical presentation, classification, imaging, medical treatment, and rehabilitation of acute PHF. METHODS/RESULTS/DISCUSSION N/A for clinical commentary. CONCLUSIONS The first step to a successful management of PHF is the clinical and radiographic examination of the shoulder, which enables the physician to classify the fracture and choose the appropriate treatment option. The Neer and OA classifications are commonly used and are based on the identification of the fractured parts of the humerus, as well as the displacement of the fragments. In case of non-displaced or minimally displaced fractures, a conservative treatment, consisting of initial immobilization and a rehabilitation program will be chosen. Displaced or unstable fractures will be managed operatively. Different surgical options exist and will vary according to the fracture type, patient's age, and functional needs, followed by rehabilitation. LEVEL OF EVIDENCE 5.

Abstract
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVE The purpose of this study was to evaluate the effect of postoperative ketorolac administration (ie, dosage and duration of use) on pseudarthrosis following thoracolumbar posterolateral spinal fusions. SUMMARY OF BACKGROUND DATA Ketorolac is a nonsteroidal anti-inflammatory drug often administered for pain control after spine surgery. The main concern with ketorolac is the risk of pseudarthrosis following fusion. MATERIALS AND METHODS A systematic search of multiple medical reference databases was conducted for studies detailing postoperative ketorolac use in lumbar fusion and scoliosis surgery in adult and pediatric patients, respectively. Meta-analysis was performed using the random-effects model for heterogeneity as this study analyzes heterogenous patient populations undergoing variable approaches to fusion and variable numbers of levels with variable means of detection of pseudarthrosis. Outcome measure was pseudarthrosis. RESULTS Overall, 6 studies totaling 1558 patients were reviewed. Pseudarthrosis was observed in 119 (7.6%) patients. Pseudarthrosis were observed in adults with ketorolac administered for >2 days [odds ratio (OR), 3.44, 95% confidence interval (95% CI), 1.87-6.36; P<0.001], adults with doses of ≥120 mg/d (OR, 2.93, 95% CI, 1.06-8.12; P=0.039), and adults with ketorolac administered for >2 days and at doses ≥120 mg/d (OR, 4.75, 95% CI, 2.34-9.62; P<0.001). Ketorolac use in smokers was associated with pseudarthrosis (OR, 8.71, 95% CI, 2.23-34.0; P=0.002). CONCLUSION Ketorolac, when administered for >2 days and/or at a dose of ≥120 mg/d, is associated with pseudarthrosis in adults after posterolateral lumbar fusion. Ketorolac use in smokers is also associated with pseudarthrosis.

Abstract
BACKGROUND Nonsteroidal anti-inflammatory drugs (NSAIDs) are often avoided by orthopaedic surgeons because of their possible influence on bone-healing. This belief stems from multiple studies, in particular animal studies, that show delayed bone-healing or nonunions associated with NSAID exposure. The purpose of this review was to critically analyze the quality of published literature that evaluates the impact of NSAIDs on clinical bone-healing. METHODS A MEDLINE and Embase search was conducted to identify all articles relating to bone and fracture-healing and the utilization of NSAIDs. All human studies, including review articles, were identified for further analysis. Non-English-language manuscripts and in vitro and animal studies were excluded. A total of twelve clinical articles and twenty-four literature reviews were selected for analysis. The quality of the clinical studies was assessed with a modified Coleman Methodology Score with emphasis on the NSAID utilization. Review articles were analyzed with regard to variability in the cited literature and final conclusions. RESULTS The mean modified Coleman Methodology Score (and standard deviation) was significantly lower (p = 0.032) in clinical studies that demonstrated a negative effect of NSAIDs on bone-healing (40.0 ± 14.3 points) compared with those that concluded that NSAIDs were safe (58.8 ± 10.3 points). Review articles also demonstrated substantial variability in the number of cited clinical studies and overall conclusions. There were only two meta-analyses and twenty-two narrative reviews. The mean number (and standard deviation) of clinical studies cited was significantly greater (p = 0.008) for reviews that concluded that NSAIDs were safe (8.0 ± 4.8) compared with those that recommended avoiding them (2.1 ± 2.1). Unanimously, all reviews admitted to the need for prospective randomized controlled trials to help clarify the effects of NSAIDs on bone-healing. CONCLUSIONS This systematic literature review highlights the great variability in the interpretation of the literature addressing the impact of NSAIDs on bone-healing. Unfortunately, there is no consensus regarding the safety of NSAIDs following orthopaedic procedures, and future studies should aim for appropriate methodological designs to help to clarify existing discrepancies to improve the quality of care for orthopaedic patients. CLINICAL RELEVANCE This systematic review highlights the limitations in the current understanding of the effects of NSAIDs on bone healing. Thus, withholding these medications does not have any proven scientific benefit to patients and may even cause harm by increasing narcotic requirements in cases in which they could be beneficial for pain management. This review should encourage further basic-science and clinical studies to clarify the risks and benefits of anti-inflammatory medications in the postoperative period, with the aim of improving patient outcomes.
