Is there a relationship between self-efficacy, disability, pain and sociodemographic characteristics in chronic low back pain? A multicenter retrospective analysis
Background: Pain-related self-efficacy is defined as the beliefs held by people with chronic pain that certain activities can be carried out despite the pain. Poor self-efficacy is an obstacle to the recovery and predicts longterm disability. The aims of this study are to investigate the prevalence of poor pain self-efficacy in Italian subjects with chronic low back pain (LBP), and to inquire the relationships between self-efficacy, disability, pain, and main demographic and clinical characteristics. Methods: A secondary multicenter retrospective analysis was done on 310 outpatients with chronic non-specific LBP. The pain self-efficacy measured with the Pain Self-Efficacy Questionnaire (PSEQ), the disability measured with the Roland & Morris Disability Questionnaire, and the pain intensity measured with the Numerical Rating Scale were considered variables to investigate, whereas demographic and clinical variables were considered predictors or potential confounders. A 40/60 PSEQ score was adopted as cut-off to distinguish between good and poor selfefficacy. Results: 199 subjects (64.2% of the sample) showed poor self-efficacy. The odds of having poor self-efficacy appeared significantly related to female gender (OR=1.80, 95%CI [1.12;2.90]; p =0.015) and drugs use (OR=1.68, 95%CI [1.06;2.70]; p=0.029). Significant relationships also emerged between disability and higher age (\u3b2=0.07, 95%CI [0.01; 0.12]; p =0.02), being female (\u3b2=1.80, 95%CI [0.32;3.29]; p=0.018), low educational level (\u3b2= 121.68, 95%CI [ 122.59;-3.29]; p<0.001), higher height (\u3b2= 120.08, 95%CI [ 120.158;-0.002]; p=0.045), pain duration [mos] (\u3b2= 0.01, 95%CI [0.001;0.021]; p=0.041), and drugs use (\u3b2=2.86, 95%CI [1.44;4.27]; p<0.001). The amount of pain appeared significantly related to educational level (\u3b2= 120.47, 95%CI [ 120.76;-0.182]; p <0.001), smoking (\u3b2=0.56, 95%CI [0.09; 1.03]; p=0.021), height (\u3b2= 120.03, 95%CI [ 120.05; 120.002]; p=0.036), and drugs use (\u3b2=0.81, 95%CI [0.399;1.22]; p <0.001). No significant correlation appeared among weight, body mass index, and referred pain neither in relation to self-efficacy, nor in relation to pain/disability. Conclusions: The majority of our sample, composed of Italian people complained of chronic LBP, shows poor selfefficacy. Female gender and drugs use are significantly related to poor self-efficacy, low educational level negatively influences the amount of perceived pain and disability, and older age and smoking are related to disability and pain intensity, respectively. The knowledge of these sociodemographic and clinical characteristics potentially influencing chronic LBP may be useful to address more efforts towards the most negatively impacted subjects, among the entire population complained of chronic LBP

Is the association of electrochemotherapy and bone fixation rational in patients with bone metastasis?
BackgroundBone metastases are frequent in patients with cancer. Electrochemotherapy (ECT) is a minimally invasive treatment based on a high-voltage electric pulse combined with an anticancer drug. Preclinical and clinical studies supported the use of ECT in patients with metastatic bone disease, demonstrating that it does not damage the mineral structure of the bone and its regenerative capacity, and that is feasible and efficient for the treatment of bone metastases. Year 2014 saw the start of a registry of patients with bone metastases treated with ECT, whose data are recorded in a shared database. Questions/Purposes(1) Among patients who underwent ECT and internal fixation for bone metastasis, how many experienced a reduction of pain? (2) How many cases showed a radiological response? (3) How many patients presented local or systemic complication after ECT and fixation? Patients and MethodsPatients were treated in Bologna at Rizzoli Orthopaedic Institute between March 2014 and February 2022 and recorded in the REINBONE registry (a shared database protected by security passwords): clinical and radiological information, ECT session, adverse events, response, quality of life indicators, and duration of follow-up were registered. We consider only cases treated with ECT and intramedullary nail during the same surgical session. Patients included in the analysis were 32: 15 males and 17 females, mean age 65 +/- 13 years (median 66, range 38-88 years), mean time since diagnosis of primary tumor 6.2 +/- 7.0 years (median 2.9, range 0-22 years). Nail was indicated in 13 cases for a pathological fracture in, 19 for an impending fracture. Follow-up was available for 29 patients, as 2 patients were lost to follow-up and 1 was unable to return to controls. Mean follow-up time was 7.7 +/- 6.5 months (median 5, range 1-24), and 16 patients (50%) had a follow-up longer than 6 months. ResultsA significant decrease in pain intensity was observed at the mean Visual Numeric Scale after treatment. Bone recovery was observed in 13 patients. The other 16 patients remained without changes, and one presented disease progression. One patient presented a fracture occurrence during the ECT procedure. Among all patients, bone recovery was observed in 13 patients: complete recovery in 1 patient (3%) and partial recovery in 12 patients (41%). The other 16 patients remained without changes, and one presented disease progression. One patient presented a fracture occurrence during the ECT procedure. However, healing was possible with normal fracture callus quality and healing time. No other local or systemic complications were observed. ConclusionWe found that pain levels decreased after treatment in 23 of the 29 cases for a pain relief rate of 79% at final follow-up. Pain is one of the most important indicators of quality of life in patients that undergo palliative treatments. Even if conventional external body radiotherapy is considered a noninvasive treatment, it presents a dose-dependent toxicity. ECT provides a chemical necrosis preserving osteogenic activity and structural integrity of bone trabeculae; this is a crucial difference with other local treatments and allows bone healing in case of pathological fracture. The risk of local progression in our patient population was small, and 44% experienced bone recovery while 53% of the cases remained unchanged. We observe intraoperative fracture in one case.This technique, in selected patients, improves outcome in bone metastatic patients combing both the efficacy of the ECT in the local control of the disease and the mechanical stability with the bone fixation to synergize their benefits. Moreover, the risk of complication is very low. Although encouraging data, comparative studies are required to quantify the real efficacy of the technique.

Injection of Demineralized Bone Matrix With Bone Marrow Concentrate Improves Healing in Unicameral Bone Cyst
Lengthening Patients Previously Treated for Massive Lower Limb Reconstruction for Bone Tumors with the PRECICE 2 Nail
The objective of this study was to determine the efficacy of the PRECICE 2® nail in the treatment of lower limb length discrepancy in patients with a history of bone tumors. This study reports on outcomes, complications, and the safety of the PRECICE 2 limb lengthening nail in a cohort of pediatric patients with limb length discrepancy after surgery for bone tumors. Seventeen patients were treated with intramedullary magnetic nails. The average patient age at the time of surgery was 19 (range 11–32). The PRECICE 2 nail was used on 14 femurs (6 retrograde and 8 anterograde) and 3 tibias. The average consolidation time was 141 days (range 50–360) with a mean CI of 31 ± 12 days/cm. The ASAMI bone score showed 14 (82%) excellent results, 1 (6%) good result, and 2 (12%) poor results. The ASAMI functional score showed 13 (84.6%) excellent results, 3 (11.5%) good results, and 1 (3.8%) fair result. Patients treated with chemotherapy for bone cancer did not show any increase in distraction time or consolidation time. A total of 3 (17%) problems, 1 obstacle (5.5%), and 1 complication (5.5%) were encountered in our case series. The PRECICE 2 nail allows for effective and accurate lengthening preserving the range of motion in patients treated for bone tumors
