Morphine-induced osteolysis and hypersensitivity is mediated through toll-like receptor-4 in a murine model of metastatic breast cancer. Pain 2023; 164:2463-2476. [PMID: 37326644 PMCID: PMC10578422 DOI: 10.1097/j.pain.0000000000002953] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 03/28/2023] [Accepted: 04/18/2023] [Indexed: 06/17/2023]
Abstract
ABSTRACT The propensity for breast cancer to metastasize to bone is coupled to the most common complaint among breast cancer patients: bone pain. Classically, this type of pain is treated using escalating doses of opioids, which lack long-term efficacy due to analgesic tolerance, opioid-induced hypersensitivity, and have recently been linked to enhanced bone loss. To date, the molecular mechanisms underlying these adverse effects have not been fully explored. Using an immunocompetent murine model of metastatic breast cancer, we demonstrated that sustained morphine infusion induced a significant increase in osteolysis and hypersensitivity within the ipsilateral femur through the activation of toll-like receptor-4 (TLR4). Pharmacological blockade with TAK242 (resatorvid) as well as the use of a TLR4 genetic knockout ameliorated the chronic morphine-induced osteolysis and hypersensitivity. Genetic MOR knockout did not mitigate chronic morphine hypersensitivity or bone loss. In vitro studies using RAW264.7 murine macrophages precursor cells demonstrated morphine-enhanced osteoclastogenesis that was inhibited by the TLR4 antagonist. Together, these data indicate that morphine induces osteolysis and hypersensitivity that are mediated, in part, through a TLR4 receptor mechanism.

Comparison of Percutaneous Interventional Ablation-Osteoplasty-Reinforcement-Internal Fixation (AORIF), Long Intramedullary Nailing, and Hemiarthroplasty for the Treatment of Focal Metastatic Osteolytic Lesions in the Femoral Head and Neck. Cardiovasc Intervent Radiol 2023; 46:649-657. [PMID: 37052716 DOI: 10.1007/s00270-023-03425-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Accepted: 03/17/2023] [Indexed: 04/14/2023]
Abstract
PURPOSE Osteolytic metastatic lesions in the femoral head and neck are traditionally treated with intramedullary long nailing (IM) or hemiarthroplasty (HA). Recovery, surgical complications, and medical co-morbidities delay oncologic care. This study sought to elucidate the comparative efficacy of percutaneous ablation-osteoplasty-reinforcement-internal fixation (AORIF), IM, and HA in stabilizing osteolytic lesions in the femoral head and neck. METHODS A retrospective study of 67 patients who underwent IM, AORIF, or HA for osteolytic femoral head and neck lesions was performed. Primary outcome was assessed using a combined pain and ambulatory score (Range 1-10: 1 = bedbound, 10 = normal ambulation) at first follow-up (~ 2 weeks). Surgical complications associated with each treatment were compared. RESULTS Sixty-seven patients (mean age, 65 ± 13, 36 men and 31 women) underwent IM (40), AORIF (19), and HA (8) with a mean follow-up of 9 ± 11 months. Two patients in the IM group (5%), three in the AORIF group (16%), and none in the HA (0%) group required revision procedures. AORIF demonstrated superior early improvement in combined pain and ambulatory function scores by 3.0 points [IQR = 2.0] (IM p = 0.0008, HA p = 0.0190). Odds of post-operative complications was 10.3 times higher in HA than IM (95% confidence interval 1.8 to 60.3). Future revision procedures were not found to be statistically significant between AORIF and IM (p = 0.234). CONCLUSIONS A minimally invasive interventional skeletal procedure for focal femoral head and neck osteolytic lesions may serve as an effective alternative treatment to traditional surgical approaches, conferring a shorter recovery time and fewer medical complications.

Abstract
Prostate adenocarcinoma metastasizes to bone and forms fragile blastic lesions, which can present as dense obstacles intraoperatively. There are limited reports on the challenges surgeons face when operating through these lesions. A 60-year-old male with a pathologic subtrochanteric femur fracture in the presence of blastic lesions was successfully treated with intramedullary (IM) fixation. Pathologic fractures from blastic bone lesions are expected to increase in prevalence as survivability improves for metastatic prostate cancer. Orthopedic surgeons, when performing IM fixation for these fractures, should be prepared to utilize accessory equipment and should adopt creative techniques for reduction and fixation.

Abstract
Humeral metastases from renal cell carcinoma are not uncommon. Current surgical practice centres around adequate tumour resection, but often at the expense of functional outcome. The use of trabecular metal (TM) implants is well described in spine and joint surgery. However, their use as a reconstruction device in osseous tumour surgery has yet to be reported. We present our experience in using a TM vertebral body replacement device (VBR) in treating a patient with painful bilateral diaphyseal humeral metastases. Resection of the tumour resulted in defects which the TM-VBR was able to fill. The defect was then bridged with a locking plate and cables. At 2-year clinical and radiographic review, bony integration and a return to pain free, near-normal function was achieved.

Abstract
INTRODUCTION Current mortality predictive tools, in the setting of completed or impending pathologic fractures, are nonspecific. Clinical decision making and mortality prediction in research would benefit from creation of a high-fidelity scoring system for calculating the risk of 30-day postoperative mortality. The purpose of this study is to develop a validated research and clinical tool that is superior to existing methods in estimating postoperative mortality risk after fixation of pathologic fractures. METHODS One thousand two hundred nineteen patients who underwent fixation for either completed or impending pathologic fractures in the National Surgical Quality Improvement Program (2012 to 2018) database were analyzed. Multivariable logistic regression with diagnostics was used to develop a predictive model in a derivation cohort and then validated in a validation cohort. Area under the curve (AUC) from receiver operator curve analysis was used to assess accuracy. A score was derived and compared with the American Society of Anesthesiologists classification and modified five-component frailty index (mF-I5). The score was validated in an exclusive cohort of patients who underwent fixation for pathologic fractures at a tertiary care center. RESULTS Of 1,219, a total of 177 (15%) patients did not survive beyond 30 days postoperatively. AUC for our predictive model was 0.76 in the derivation and 0.75 in the validation National Surgical Quality Improvement Program cohorts. The derived Pathologic Fracture Morbidity Index included seven data points: anemia, alkaline phosphatase > 150 U/L, albumin < 3.5 mg/dL, pulmonary disease, recent weight loss, functional dependence, and white blood cell count >12,000. The PFMI (AUC = 0.75) was more accurate than ASA (AUC = 0.60) or mF-5 (AUC = 0.58) (P < 0.01). The AUC for PFMI in predicting 30-day mortality in the exclusive cohort (N = 39) was 0.74. CONCLUSION The PFMI is a validated tool that may be used for predicting postoperative 30-day mortality after fixation of pathologic fractures, with higher level of accuracy compared with ASA or mF-I5.

Treatment of Pathologic Peritrochanteric Fractures Using Sliding Hip Screws Augmented with Cerclage Reconstruction Plates. J Clin Med 2021; 10:jcm10184271.

Abstract
We proposed a new method to augment the traditional sliding hip screw (SHS) with cerclage reconstruction plates to treat pathologically impending and actual peritrochanteric fractures as well as to revise open reductions and internal fixations to increase the construct strength against the shearing force, thus reducing the implant failure rate. In this retrospective study, patients with peritrochanteric pathology with at least two years of follow-up who underwent augmentation with cerclage reconstruction plates (modified SHS) and conventional SHS between 1 May 2015 and 31 May 2017 were divided into groups A (n = 12) and B (n = 28), respectively. Demographic data, surgery duration, blood loss, complications, and local radiotherapy were analyzed. The average surgery duration was significantly longer in group A (p = 0.013). The estimated intraoperative and perioperative blood losses were not significantly different between the groups. The implant survival rates were not significantly different under competing risk analysis. The success rate of a revision surgery with modified SHS was excellent, and implant survival time was >2 years, as observed with the previous SHS constructs. Subtrochanteric region involvement and a postoperative visual analog scale ≥4 could be risk factors of implant failure and revision surgery. This technique can be an alternative treatment for difficult pathologic peritrochanteric fractures, especially those with previous plating failure.

Abstract
INTRODUCTION Histologic diagnosis of the lesion is important while intramedullary nailing of a pathologic or impending fracture of a long bone. A biopsy can be performed extramedullary using a targeted sampling device such as a pituitary rongeur or intramedullary from the bone removed from the reamer during preparation of the intramedullary canal. The purpose of this study is to compare a cup pituitary rongeur vs. a reaming biopsy from the intramedullary canal during the treatment of pathologic bone lesions with an intramedullary nail. METHODS An IRB approved retrospective case control study was performed on 46 consecutive patients who underwent an IMN for pathologic fracture or impending pathologic fracture with an obvious lytic lesion with a known metastatic primary. A laryngeal cup pituitary forceps' rongeur was used in 25 patients and the intramedullary reamer as it passed the lesion was used in 21 patients. Histopathology reports were assessed for (1) adequacy of bone sample (defined as containing sufficient bone and marrow-derived tissue to allow complete histological analysis) and (2) tumor tissue diagnosis. A standard approach for IMN was used. RESULTS Twenty-three of 25 cup biopsy cases (92%) had positive pathology that corresponded to the primary cancer. Eleven of 21 reaming cases (52.4%) had positive pathology that corresponded to the primary cancer (p = 0.0117). CONCLUSION The use of an intramedullary cup biopsy forceps is better than reamings to diagnose pathological lesions of impending and pathological fractures in long bones caused by metastatic lesions.

Abstract
In the event of surgical management of metastases to the humeral shaft, intramedullary nailing (IMN) is often preferred to plate osteosynthesis (PO) fixation despite a lack of consensus. In this study, we hypothesized that plate osteosynthesis will be associated with better functional and pain outcomes, thus better quality of life. Eighteen patients with the diagnosis of humeral shaft metastatic fracture or impending fracture were extracted from a prospective database of 140 metastatic patients collected across three hospitals over a five-year period. Musculoskeletal Tumor Society (MSTS) score, Toronto Extremity Salvage Score (TESS), Quality of Life (QOL) and Brief Pain Inventory (BPI) score were gathered during the year following the surgery. Statistical analysis was performed to compare the mean score differences between the two surgical options at baseline and five follow-up visits. Both treatment options were associated with an increase in functional outcomes based on both MSTS and TESS, and a decrease in pain level. However, no significant difference was found in quality of life and between the two treatment modalities. Thus, based on our results, a similar improvement in functional status and pain level can be achieved surgically by either intramedullary nailing or plating osteosynthesis.

Abstract
CASE A 72-year-old man underwent intramedullary nailing of a humeral diaphysis fracture with passage through an unrecognized pathologic fracture. Four months later, a biopsy of a soft-tissue mass in the arm revealed pleomorphic undifferentiated sarcoma. Only after local recurrence and forequarter amputation was the story of a pathologic fracture through undifferentiated pleomorphic sarcomas of bone clear. The patient developed metastatic disease and died after 2 years postoperatively. DISCUSSION Orthopaedic surgeons should consider sarcoma when assessing patients with fractures of unknown etiology and an inappropriate mechanism because the placement of an intramedullary device through a sarcoma of bone has consequences.

Abstract
BACKGROUND The purpose of this investigation was to identify and summarize the current utility of intramedullary tissue sampling during long bone internal fixation (IF) for metastatic bone disease (MBD). The secondary aim was to provide the experience of a single institution using this technique. METHODS First, a systematic database query of the Cochrane Central Register of Controlled Trials (1976 to 2020), Cochrane Database of Systematic Reviews, Ovid MEDLINE (1946 to 2020), EMBASE, and PubMed (1964 to 2020) was performed. Following article identification, a description of the method of sampling and yield was recorded. Second, an institutional cohort was identified following Institutional Review Board approval. Cases of MBD treated with IF from 2018 to 2020 were reviewed. Data were collected and recorded from cases during which intramedullary reamings were sent for histopathology. RESULTS Ten studies met inclusion criteria. Four of the ten were techniques or technical notes. The remaining six were retrospective reviews in which tissue was sent for histopathology. Among those six, a total of 262 tissue samples were sent, and a negative result was recorded in 37.2% (n = 97) of cases. A total of 18.0% (n = 47) were noted as inadequate for interpretation. For reamings-only studies, the negative rate was higher at 50.5%. In our institutional cohort, a total of 16 tissue samples were sent in the setting of known MBD. The negative rate was 37.5% (n = 6), with zero instances of a change in clinical management after a positive result. CONCLUSION There are limited descriptions of intramedullary tissue sampling during IF of long bones for MBD. The existing literature, along with our institutional data, suggest this technique is less than optimal for tissue retrieval given the high rates of negative results from samples sent for histopathology. Furthermore, given the lack of clinical impact of a positive sample, we believe a multidisciplinary group should discuss preoperatively the utility of whether treatment might change based off a tissue diagnosis.Level of Evidence: V.

Abstract
The goal of this study was to report the clinical outcomes of pathologic humeral shaft fractures treated with reamed or unreamed intramedullary nail fixation in an era of longer patient survival. A retrospective review was conducted of all patients who underwent intramedullary nail fixation performed by a single surgeon for pathologic humeral shaft fractures at a Level I trauma center from 2009 to 2017. Of the 25 patients who were identified, 9 were excluded. Groups were categorized according to whether they underwent reamed or unreamed fixation, and they were evaluated for evidence of union, complications, and reoperation. Of the patients, 11 underwent an unreamed procedure and 5 underwent a reamed procedure. Mean length of follow-up was 51.5 weeks. Of the patients who participated, 12 (75%) showed evidence of union and 2 patients (12.5%) showed evidence of nonunion, with no statistical difference between the groups. Five patients (31.3%) had complications. One nonunion occurred in the reamed group and did not require reoperation. In the unreamed group, complications consisted of 1 delayed union, 1 nonunion treated with revision intramedullary nail fixation, and 2 cases of disease progression that required reoperation. Intramedullary nail fixation of pathologic humeral shaft fractures achieves rates of union parallel to those seen with fixation in a healthy population. The length of follow-up in the current study was longer than the life expectancy reported by previous authors, which can be attributed to improvements in the treatment of cancer. The current authors argue that unreamed fixation is the optimal technique because it yields similar outcomes to a reamed approach and is faster and potentially safer.

Abstract
Patients with bone metastases have an increased risk to sustain a pathological fracture as lytic metastatic lesions damage and weaken the bone. In order to prevent fractures, prophylactic treatment is advised for patients with a high fracture risk. Mechanical stabilization of the femur can be provided through femoroplasty, a minimally invasive procedure where bone cement is injected into the lesion, or through internal fixation with intra- or extramedullary implants. Clinicians face the task of determining whether or not prophylactic treatment is required and which treatment would be the most optimal. Finite element (FE) models are promising tools that could support this decision process. The aim of this paper is to provide an overview of the state-of-the-art in FE modeling for the treatment decision of metastatic bone lesions in the femur. First, we will summarize the clinical and mechanical results of femoroplasty as a prophylactic treatment method. Secondly, current FE models for fracture risk assessment of metastatic femurs will be reviewed and the remaining challenges for clinical implementation will be discussed. Thirdly, we will elaborate on the simulation of femoroplasty in FE models and discuss future opportunities. Femoroplasty has already proven to effectively relieve pain and improve functionality, but there remains uncertainty whether it provides sufficient mechanical strengthening to prevent pathological fractures. FE models could help to select appropriate candidates for whom femoroplasty provides sufficient increase in strength and to further improve the mechanical benefit by optimizing the locations for cement augmentation.

Abstract
This study investigates the distribution of femoral metastases in cancer patients, specifically addressing the incidence of distal femoral metastases. PET/CT examinations routinely extend only to mid-thigh level, precluding detection of distal metastases. We found a total of 208 femoral metastases in 112 patients. 30% had distal femoral metastases in addition to other areas of involvement. 7% of patients with femoral metastases had only distal femur disease. 6 patients had distal pathologic fractures. Exclusion of the distal femur during PET/CT may result in a missed or delayed diagnosis that could contribute to the development of a pathologic fracture with increased morbidity.

Abstract
Objective: To compare preoperative and early postoperative levels of psychosocial
distress in patients undergoing bone metastasis treatment with
endoprosthesis, evaluating its impact on quality of life. Methods: Thirteen patients undergoing endoprosthetic treatment of bone metastasis were
assessed at two time points: preoperatively and 30 days postoperatively. The
tool used was the Distress Thermometer, a questionnaire for psychosocial
screening developed by the National Comprehensive Cancer Network. Distress
is considered moderate or severe if the patient scores 4 or higher. Results: The most frequent problems in the preoperative period were “bathing and
dressing”. At 30 days, “fatigue” and “nervousness” prevailed. There was a
significant improvement in distress when preoperative and 30-day assessments
were compared. Conclusion: The surgical treatment of bone metastasis with endoprosthesis results in an
early improvement of psychosocial distress as measured by the Distress
Thermometer. Level of evidence II, Prospective and comparative therapeutic
study.

Abstract
INTRODUCTION The goals of orthopaedic treatment for most patients with osseous metastases are to control pain, maintain function, and maximize quality of life and time at home. The aim of this study was to determine differences in 30-day postoperative morbidity and mortality between patients who underwent prophylactic versus postfracture stabilization for metastatic lesions of long bones. METHODS The American College of Surgeons National Surgical Quality Improvement Program database was queried for patients who underwent prophylactic fixation (n = 461) or postfracture stabilization (n = 856) for pathologic fractures because of metastatic lesions of long bones from 2006 to 2016. The groups were compared with respect to several potential confounders using Student t, Kruskal-Wallis, and χ tests. Logistic and Poisson regression models (inclusion threshold of P < 0.1) were used to assess the associations of functional status with outcomes. The alpha level was set at 0.05. RESULTS Prophylactic fixation was associated with a lower risk of major medical complications (odds ratio = 0.64; 95% confidence interval [CI], 0.45 to 0.93; P = 0.02), discharge to a care facility rather than home (odds ratio = 0.48; 95% CI, 0.36 to 0.63; P < 0.01), and lower risk of a longer hospital stay (incidence risk ratio = 0.86; 95% CI, 0.74 to 0.96; P = 0.01) compared with postfracture stabilization. No significant difference was found in the risk of unplanned revision surgery or 30-day postoperative mortality between the two groups. CONCLUSION Although prevention of pathologic fractures caused by metastatic disease may not always be possible, patients who underwent prophylactic stabilization had a lower risk of major complications within 30 days postoperatively and shorter hospital stays compared with patients who underwent postfracture stabilization. LEVEL OF EVIDENCE Level IV, retrospective cohort.
