Preoperative Pain Sensitization Is Associated With Postoperative Pillar Pain After Open Carpal Tunnel Release.
CONCLUSIONS: Gender (women) and preoperative pain sensitization measured by pressure pain threshold and self-reported Pain Sensitivity Questionnaire were associated with pillar pain severity up to 3 and 6 months after CTR, respectively. However, the influence of pain sensitization on pillar pain was diminished at 6 months and it did not show persistent effects beyond 12 months. Pain sensitization seems to be more important in the context of recovery from surgical intervention (in the presence of a pain condition) than in healthy states, and clinicians should understand the role of pain sensitization in the postoperative ma...

Do Pain Coping and Pain Beliefs Associate With Outcome Measures Before Knee Arthroplasty in Patients Who Catastrophize About Pain? A Cross-sectional Analysis From a Randomized Clinical Trial.
Abstract BACKGROUND: Pain-coping strategies and appraisals are responses to the pain experience. They can influence patient-reported and physical performance outcome measures in a variety of disorders, but the associations between a comprehensive profile of pain-coping responses and preoperative pain/function and physical performance measures in patients scheduled for knee arthroplasty have not been examined. Patients with moderate to high pain catastrophizing (a pain appraisal approach associated with an exaggerated focus on the threat value of pain) may represent an excellent study population in which to address...

Can Aortic Balloon Occlusion Reduce Blood Loss During Resection of Sacral Tumors That Extend Into the Lower Lumber Spine?
CONCLUSIONS: This study demonstrated that placement of the aortic balloon at a level just caudal to the renal artery bifurcation was associated with lower intraoperative blood loss and transfusion in lumbosacral tumor resections. However, procedure-specific complications were common and there was no benefit to total operative time. We suggest that the surgical procedures still need to be further refined to minimize complications. We also recommend that prospective studies be undertaken to confirm the efficacy of aortic balloon occlusion in surgery for lumbosacral tumors. LEVEL OF EVIDENCE: Level III, therapeutic study...

Can Navigation-assisted Surgery Help Achieve Negative Margins in Resection of Pelvic and Sacral Tumors?
CONCLUSIONS: Navigation-assisted resection of pelvic and sacral tumors resulted in a high likelihood of negative margin resection in this series, and we observed relatively few complications related specifically to the navigation. We have no comparison group without navigation, and future studies should indeed compare navigated with nonnavigated resection approaches in these anatomic locations. We did identify a potential navigation-related complication of femoral nerve palsy in this series and suggest careful placement and observation of the reference array during the operative procedure to lessen the likelihood of this p...

Is Navigation-guided En Bloc Resection Advantageous Compared With Intralesional Curettage for Locally Aggressive Bone Tumors?
CONCLUSIONS: In this small comparative series, navigation-assisted resection techniques allowed conservative en bloc resection of locally aggressive primary bone tumors with no local recurrence. Nevertheless, with the numbers available, we saw no difference between the groups in terms of local recurrence risk, complications, or function. Until or unless studies demonstrate an advantage to navigation-guided en bloc resection, we cannot recommend wide use of this novel technique because it adds surgical time and expense.

What Is the Effect of High-dose Radiation on Bone in Patients With Sacral Chordoma? A CT Study.
Abstract BACKGROUND: Effects of high-dose radiation using protons and photons on bone are relatively unexplored, but high rates of insufficiency fractures are reported, and the causes of this are incompletely understood. Imaging studies with pre- and postradiation scans can help one understand the effect of radiation on bone. QUESTIONS/PURPOSES: The purpose of this study was to assess the effects of high-dose radiation on the trabecular density of bone in the sacrum using CT-derived Hounsfield units (HU). METHODS: Between 2009 and 2015, we treated 57 patients (older then 18 years) with sacral chordoma. F...

Early Improvement in Pain and Functional Outcome but Not Quality of Life After Surgery for Metastatic Long Bone Disease.
Abstract BACKGROUND: Bone metastases represent the most frequent cause of cancer-related pain, affecting health-related quality of life and creating a substantial burden on the healthcare system. Although most bony metastatic lesions can be managed nonoperatively, surgical management can help patients reduce severe pain, avoid impending fracture, and stabilize pathologic fractures. Studies have demonstrated functional improvement postoperatively as early as 6 weeks, but little data exist on the temporal progress of these improvements or on the changes in quality of life over time as a result of surgical interventi...

MRI Identification of the Osseous Extent of Pediatric Bone Sarcomas.
Abstract BACKGROUND: The quantitative accuracy of MRI in predicting the intraosseous extent of primary sarcoma of bone has not been definitively confirmed, although MRI is widely accepted as an accurate tool to plan limb salvage resections. Because inaccuracies in MRI determination of tumor extent could affect the ability of a tumor surgeon to achieve negative margins and avoid local recurrence, we thought it important to assess the accuracy of MR-determined tumor extent to the actual extent observed pathologically from resected specimens in pediatric patients treated for primary sarcomas of bone.

Synovial Sarcoma Is Not Associated With a Higher Risk of Lymph Node Metastasis Compared With Other Soft Tissue Sarcomas.
Abstract BACKGROUND: Reported rates of the incidence of lymph node metastasis in soft tissue sarcoma vary considerably. Many are based on single-institution series and small patient populations. Certain sarcoma subtypes, including synovial sarcoma, have been associated with a higher risk of lymph node involvement. Most single centers have insufficient numbers of patients to assess lymph node metastasis accurately, but larger national databases may allow a more accurate estimation.

Does an Algorithmic Approach to Using Brachytherapy and External Beam Radiation Result in Good Function, Local Control Rates, and Low Morbidity in Patients With Extremity Soft Tissue Sarcoma?
CONCLUSIONS: In this single-institution study, an algorithmic approach to using HDR-BT and EBRT in the treatment of patients with high-grade soft tissue sarcomas can yield acceptable complication rates, good morbidity outcome scores, and a high degree of local control. Based on these results, we believe HDR-BT is best for patients with an anticipated close margin, a positive surgical margin, and for patients who are unlikely to receive a complex soft tissue procedure. Conversely, if a secondary procedure and/or soft tissue coverage are likely to be used, EBRT alone may be reasonable. Finally, combination therapy might be c...

Longitudinal Growth and pQCT Measures in Hutterite Children and Grandchildren Are Associated With Prevalence of Hip or Knee Replacement Resulting From Osteoarthritis in Parents and Grandparents.
Abstract BACKGROUND: Osteoarthritis (OA) is one of the leading causes of disability in the world. Several genes are associated with the development of OA, and previous studies have shown adult children of individuals with OA have higher areal bone mineral density (BMD). Because childhood is an important period of growth and bone development, and body composition is known to be associated with BMD, we speculated that there may be differences in growth and bone measures among young children with a genetic predisposition to OA. QUESTIONS/PURPOSES: (1) Do differences exist at baseline in anthropometric and periph...

Looking for Holes in Sterile Wrapping: How Accurate Are We?
Abstract BACKGROUND: Defects in sterile surgical wrapping are identified by the presence of holes through which light can be seen. However, it is unknown how reliably the human eye can detect these defects. QUESTIONS/PURPOSES: The purpose of this study was to determine (1) how often holes in sterile packaging of various sizes could be detected; and (2) whether differences in lighting, experience level of the observer, or time spent inspecting the packaging were associated with improved likelihood of detection of holes in sterile packaging. METHODS: Thirty participants (10 surgical technicians, 13 operati...

Effectiveness of Preoperative Antibiotics in Preventing Surgical Site Infection After Common Soft Tissue Procedures of the Hand.
CONCLUSIONS: Antibiotic prophylaxis for common soft tissue procedures of the hand is not associated with reduction in postoperative infection risk. While our analysis cannot account for factors that are not captured in the billing process, this study nevertheless provides strong evidence against unnecessary use of antibiotics before these procedures, especially given the difficulty of conducting a randomized prospective study with a sample size large enough to detect the effect of prophylaxis on the low baseline risk of infection. LEVEL OF EVIDENCE: Level III, therapeutic study. PMID: 29432267 [PubMed - as suppli...
