Abstract Introduction: The integrity and composition of bone marrow core biopsies may be influenced by many parameters including patient age, sex, bone density, operator experience, needle selection and biopsy technique. Biopsy needle design impacts on a needle’s performance and the quality of recovered specimens. We studied the effect of modifying the Snarecoil bone marrow biopsy needle tip on the recovery of trabecular bone in core specimens. Methods: 7 patients, ages 35–92, M/F = 4/3, (2 leukemias, 1 lymphoma, 1 cytopenia, 1 anemia, 2 other) underwent a bone marrow biopsy using a 8 gauge Snarecoil needle with a new needle tip (TPNSP). The tip has a twin peak point and more distal Snarecoil position. As a control group, 7 patients biopsied with a standard 8 gauge Snarecoil needle (NTP) were retrospectively identified and matched for age and sex and were ages 37–87, M/F = 5/2, (3 cytopenias, 2 leukemias, 1 lymphoma, 1 other). All biopsies were completed using a minimally manipulative technique from the left posterior superior iliac spine with 2% lidocaine. The length of the specimen and attached clot was measured. The specimens were decalcified for 90 minutes and otherwise processed in the standard fashion. The percentage of bone per core biopsy was determined with computer-assisted morphometry using a BioGenex iVision V3.5 system. Results: The study and control groups were comparable, as the mean age and M/F distribution of the two groups and the mean lengths of the recovered specimens were not statistically significantly different. (TPNSP vs. NTP, 63.8±7.1 vs. 64.7± 6.4 p=0.93, 4/3 vs.5/2 p= 0.57, 2.32± 0.26cm vs. 2.21± 0.26cm p=0.761, respectively). Needle Age M/F Specimen Length % Bone TPNSP 63.8±7.1 4/3 2.32±0.26 (1.2–3.3) 16.3±1.5 (12.1–21.8) NTP 64.7±6.4 5/2 2.21±0.26 (1.3–2.9) 6.8±1.4 (2.9–12.5) However, the mean percentage of bone in the specimens recovered by the new TPNSP needle was greater than that recovered with the NTP needle. (16.3±1.5% vs. 6.8±1.4%, p= 0.0008). Grossly, the TPNSP specimens had a more linear edge than those of the NTP specimens. Also, more (5/7) of the NTP specimens had > 0.5 cm of attached clot then did the TPNSP specimens (0/7), p=0.005 suggesting that the twin peak needle produced less tissue hemorrhage. Conclusions: 1. 8 gauge Snarecoil needles having a sharper tip and more distal Snarecoil recover specimens with as much as 2.5 fold more bone for histopathologic study. 2. The twin peak needle may produce less tissue hemorrhage and disruption.

Abstract Introduction. An ideal biopsy needle consistently recovers representative specimens of adequate length with minimal dependence on patient characteristics. We have shown that bone marrow biopsy needle gauge influences the length and quantity of recovered specimens. A needle that performs independently of patient characteristics should yield specimens demonstrating a normal distribution of specimen lengths. We evaluated the influence of age and needle gauge on the specimen length distribution curves of patients undergoing bone marrow biopsies using SNARECOIL needles. Methods. 88 bone marrow core specimens were recovered from 72 patients using 11G SNARECOIL bone marrow biopsy needles. The mean age of the patients was 61.4 and the m/f ratio was 45/27. 53 specimens were recovered from 39 patients (mean age = 47.1, m/f = 27/12) ≤ 64 and 35 specimens were recovered from 33 patients (mean age = 78.6, m/f = 18/15) ≥ 65. 106 patients underwent 127 bone marrow biopsy procedures using 8G SNARECOIL needles. The m/f ratio was 56/50 and the mean age of the patients was 63.1 years. 72 specimens were recovered from 56 patients (mean age = 51.4, m/f = 30/26) ≤ 64 years old and 55 specimens were recovered from 49 patients (mean age = 76.1, m/f = 26/23) ≥ 65. 40 additional specimens were prospectively recovered from 39 patients ≥ 65 (mean age = 74.3, m/f = 19/20) with 8G SNARECOIL needles. Results. The mean specimen lengths of the 11G and 8G specimens were statistically the same (mean±SEM, 1.97±0.07 cm vs. 1.99±0.05 cm, respectively, p = 0.8). However the 11G specimen length frequency distribution curve deviated markedly from a normal distribution (skewness(skw) = 0.52) while the 8G specimen distribution was nearly normal (skw = 0.04). While the frequency distribution curves of older patients (≥ 65) biopsied with 8G needles showed minimal deviation from normality (skw = 0.12,) the distribution curve of older patients (≥65) biopsied with 11G needles deviated markedly from a normal curve (skw = 0.64). 40 specimens prospectively obtained from patients ≥ 65 demonstrated a mean specimen length of 1.77±0.09 cm with a near normal specimen length frequency distribution curve (skw = 0.07). Conclusions. 1. Although commonly reported, mean specimen lengths do not completely characterize the performance of biopsy needles. 2.0 Specimen length frequency distribution curves provide added characterization of needle performance in defined patient cohorts. 3.0 In the older patient population, near-normal 8G specimen frequency distributions and skewed 11G distributions suggest that 8G specimens may provide more representative sampling.

Abstract Abstract 1523 Introduction: A battery-powered bone marrow biopsy system was cleared by the U.S. Food and Drug Administration in 2007 for bone marrow sampling. A study was designed to determine if the powered device has advantages over traditional manual devices in terms of decreased pain, insertion time, and improved sample yield. Methods: The study protocol was approved by IntegReview Institutional Review Board. The study was conducted in a community cancer center. Pain-free adult volunteers, not on analgesics or anxiolytics, were enrolled in the study. Patients were not informed which needle was proprietary or being used with each procedure. Noise cancelling headphones and sham drill sound during manual insertions were employed. They were also uninformed as to which device was proprietary. After history, physical (including complete blood count) and consenting procedures, volunteer subjects were randomized to first pass device type and first-pass procedure side (left or right). Following local anesthesia administration using buffered Lidocaine, device operators (board-certified in hematology/oncology) performed the procedures using a Jamshidi® 11 gauge/4” Manual bone marrow biopsy needle (Havel, Inc. Richmond, VA) and an OnControl™ 11 gauge/102mm Powered bone marrow biopsy needle (Vidacare Corporation, Shavano Park, TX). A 100mm visual analog scale (VAS) was used to assess pain at initial biopsy needle insertion through the cortex, needle advancement for core sample capture, and needle removal—followed by a VAS measurement of the overall procedure pain and a final check 30 minutes after the procedure. After the second procedure, subjects were given a chance to change their overall pain score for the first procedure (“second look overall pain score”). Follow-up assessment for VAS and complications were made 1 day, 2 days, and 7 days after the biopsy procedures. Procedure time was measured from needle-to-skin contact to core specimen ejection from the needle. Core specimens were measured for length and submitted to pathology reference laboratory for grading. Pathology assessment included size measurement, post-fixation quality, medullary component quality, and overall quality. Results: There were 24 evaluable subjects the study. The mean age was 33.8 ± 11.3 years, and 54.2% were male. Mean height and weight were 169.7 ± 10.8cm and 77.0 ± 17.7kg, respectively. Of the 24 evaluable subjects, there were 24 manual insertions and 24 powered insertions. Cores were obtained in 67% of the Manual insertions and 100% of Powered insertions—a significant difference (p=0.002). The mean time to core acquisition was 86 seconds for Manual device and 47 seconds for the Powered device, a significance difference (p<0.001). Using the second look overall pain score (for those that opted to change their score), the mean score for the Manual device was 33.3 and 20.9 for the Powered—a significant difference (p<0.05). There was no statistical or clinical difference in other pain scores between the two devices. The mean biopsy core length was 11.1 ± 4.5mm for the Manual device and 17.0 ± 6.8mm for the Powered device (Figure 1); a statistical difference (p<0.005). Pathology assessment for the Manual device showed mean length of 6.08 ± 5.59mm, width of 0.98 ± 0.74mm, and mean volume of 11.00 ± 10.76mm3. Measurements for the Powered device were mean length of 15.29 ± 6.12mm, width of 1.98 ± 0.31mm, and mean volume of 49.12 ± 21.45mm3. All differences were statistically significant with p-values <0.001. For overall quality, 33.3% of Manual samples and 79.2% of Powered samples were graded adequate—a statistical difference (p=0.002). There were no complications. Conclusions: Results suggest the superior size and overall quality of core specimens delivered by the Powered device may provide more material for pathological evaluation of hematopoietic and oncological disorders. The powered device was significantly faster in obtaining a biopsy than the manual device and its capture rate in obtaining a satisfactory sample was much higher. Use of the Powered bone marrow biopsy device significantly decreases overall procedure pain. Disclosures: Miller: Vidacare Corporation: Employment, Equity Ownership, Patents & Royalties.

Abstract Background Bone marrow biopsy is a common medical procedure for diagnosis and characterization of haematological diseases. It is generally regarded as a safe procedure with low rate of major complications. Inadvertent vascular injury is however an uncommon but important complication of bone marrow biopsy procedure. The knowledge of a safe and effective embolization method is crucial for interventional radiologists to reduce significant patient morbidity and mortality, shall such inadvertent vascular injury occurs. Case presentation Bedside bone marrow biopsy was performed for an elderly gentleman to evaluate for his underlying acute leukaemia. Biopsy needle inadvertently injured the internal iliac artery and vein during the procedure. Coil embolization was carefully performed across injured arterial segment via the culprit biopsy needle until contrast cessation. Concomitant venous injury was subsequently confirmed on angiography when the needle was withdrawn for a short distance from the iliac artery. This venous injury was tackled by further withdrawing the biopsy needle to distal end of the bone marrow tract for tract embolization with coils and gelatin sponges. High caution was made to avoid coil dislodgement into the iliac vein, to prevent pulmonary embolism. Patient was clinically stable throughout the procedure. Post-procedure contrast CT shows no pelvic haematoma or contrast extravasation. Conclusions This case illustrates rescue embolization techniques for rare life-threatening concomitant internal iliac arterial and venous injuries by a bone marrow biopsy needle. Interventional radiologists can play an important role in carrying out precise embolization to avoid significant patient morbidity and mortality in the case of life-threatening haemorrhage.

Background The aim of this study is to investigate the role of diffusion-weighted imaging (DWI) in the differential diagnosis of sacroiliitis. Purpose To compare the sacroiliac magnetic resonance imaging (MRI) examinations of patients with suspected active sacroiliitis with patients with acute SpA MR findings and the DWI examinations of patients with acute brucella sacroiliitis, and thereby determine whether DWI can contribute to the differential diagnosis. Material and Methods A total of 84 patients were included in the study and were separated into three groups: group 1 (13 women, 6 men) comprised cases with brucella positive for sacroiliitis; group 2 (17 women, 19 men) comprised cases negative for brucella but with sacroiliitis; and group 3 (16 women, 13 men) comprised cases negative for brucella and sacroiliitis. Results The mean bone marrow apparent diffusion coefficient (ADC) values independently of edema were determined as 0.71 × 10−3 in sacroiliitis and brucella-positive patients, as 0.53 × 10−3 in brucella-negative and sacroiliitis-positive patients, and as 0.43 × 10−3 in the control group of brucella-negative sacroiliitis-negative patients. In the ADC measurements taken from areas of evident edema in patients with sacroiliitis, the mean values were 0.13 × 10−3 in the brucella-positive group and 0.12 × 10−3 in the brucella-negative group. Conclusion By adding DWI, which is a rapid MR sequence, to sacroiliac joint MR examination, normal bone marrow and bone marrow with sacroiliitis can be objectively differentiated with ADC measurements in addition to visual evaluation.

Purpose. To evaluate differences of Achilles tendon (AT) hardness and morphology between asymptomatic tendons in patients with acute AT ruptures on the contralateral side and asymptomatic tendons in healthy people by using computer-assisted quantification on axial-strain sonoelastography (ASE). Methods. The study consisted of 33 asymptomatic tendons in 33 patients (study group) and 34 tendons in 19 healthy volunteers (control group). All the tendons were examined by both ASE and conventional ultrasound. Computer-assisted quantification on ASE was applied to extract hardness variables, including the mean (Hmean), 20th percentile (H20), median (H50) and skewness (Hsk) of the hardness within tendon, and the ratio of the mean hardness within tendon to that outside tendon (Hratio) and three morphological variables: the thickness (THK), cross-sectional area, and eccentricity (ECC) of tendons. Results. The Hmean, Hsk, H20, H50, and Hratio in the proximal third of the tendon body in study group were significantly smaller than those in control group (Hmean: 0.43±0.09 vs 0.50±0.07, p=0.001; Hsk: -0.53±0.51 vs -1.09±0.51, p<0.001; H20: 0.31±0.10 vs 0.40±0.10, p=0.001; H50: 0.45±0.10 vs 0.53±0.08, p<0.001; Hratio: 1.01±0.25 vs 1.20±0.23, p=0.003). The THK and cross-sectional area of tendons in the study group were larger than those in the control group (p<0.05). Conclusions. As a quantitative objective method, the computer-assisted ASE reveals that the asymptomatic ATs contralateral to acute rupture are softer than those of healthy control group at the proximal third and the asymptomatic tendons in people with rupture history are thicker, larger, and rounder than those of normal volunteers especially at the middle and distal thirds of AT body.

Objectives: The purpose of the current study is to review the results of meniscus repairs with and without bone marrow aspiration concentrate (BMAC). It is hypothesized that with BMAC, meniscus repair outcomes will be improved when compared to without BMAC at 1 year after surgery. Methods: This is a prospective case control study performed from August 2014 until August 2017. Patients were included if they had a meniscus repair performed with no history of prior meniscus surgery to the operative knee. Patients were excluded if there was a full thickness cartilage tear or International Cartilage Repair Society (ICRS) Grade IV cartilage tear not treated in a single staged surgery. Patients were also excluded if they did not reach the one year follow-up, had a multi-ligamentous knee injury requiring multiple staged procedures. From August 2014 until November 2015, patients had meniscus repair without BMA. Menisci were all repaired arthroscopically using inside-out, outside-in and all-inside techniques. After November 2015, all meniscus repairs were augmented with BMAC. In the BMAC group, all bone marrow was obtained from the ipsilateral femur during the time of surgery. The Biocue BMAC system (Zimmer Biomet, Warsaw Indiana) was used for bone marrow aspiration and BMAC was injected directly into the tear site after repair. Numerical data such as VAS, lysholm and IKDC was analyzed using a 2 sample T-test. Categorical data such as sex, tear location, type of tear and zone of tear were analyzed using a chi-square. Results: A total of 150 patients were initially included in the study. The average age in the control group was 26.3 versus 29.4 in the BMAC group (P=0.27). Thirty seven percent of the control group had an ACL reconstruction versus 40% in the BMAC group (P= .77). The control group improved from an average pain level of 6.1 to 1.2 and the BMAC group improved from an average pain level of 5.9 to 0.7 at the 1 year end point. Both the control group and BMAC group improved with respect to pain with no difference at the 1 year end point (P=.19). There was, however a significantly larger reduction in pain at the 6 week and 3 month time point with BMAC compared to the control group (P=.02 and P=.02 respectively). At the 1-year follow-up, the mean lysholm score improved from 43 to 92 in the control group and 43 to 90 in the BMAC group. The mean IKDC score improved from 37 to 87 in the control group and 36 to 83 in the BMAC group at the one year follow-up. Conclusion: Meniscus repair outcomes were improved at 6 weeks and 3 months post-operatively, when BMAC is used to augment meniscus repair compared to repair without BMAC. Both groups, control group and BMAC meniscus repair group had improved outcomes at 1 year post-operatively with respect to VAS, lysholm and IKDC, with no difference in complication rate.

Abstract Mice, unlike rats and humans, have a self recovery mechanism of spinal cord injury. Whether the hematopoietic system is involved in this mechanism is under investigation. In this study we tested whether bone marrow cells transplanted or mobilized by a growth factor in mice with spinal cord injury, can accelerate the recovery. C57bl/6 female mice 10 to 12 weeks of age underwent spinal cord incision in an open operation. The injury was performed as a complete transection including the dura mater and the whole circumference of the cord at the T10-T11 intervertebral space with a micro scalpel (No 11). Group A mice received 200μg/kg/day G-CSF subcutaneously for 7 days, starting 24 hours after operation. Group B mice received 106 light density bone marrow cells from C576bl/6 donor mice intravenously 24 hours after operation. Control group mice received no treatment. Histological evaluation was performed at 48 hours, 1 week, 3 weeks and 5 weeks postoperatively. Paraffin embedded longitudinal samples of spinal cord were cut as serial sections. Spinal cord damage was estimated by measuring the maximum diameter of the area of axonal damage and disruption of astrocytic network using immunostaining for neurofilaments and GFAP. Antibodies against CD68 were applied to identify macrophage aggregations. All measurements were performed by morphometric photo analysis. The volume of fibroblastic infiltration was estimated using a grading system (0–7), based on Van Gieson stain for connective tissue. Functional deficits and recovery over time were evaluated by testing hind limb reflex and coordinated motor function (Kuhn and Wrathal functional tests, modified by Seki et al, 2002). All tests have been videotaped. Outcome scores at 48 hours, 1 week, 3 weeks and 5 weeks postoperatively for the control group, group A and group B mice were analyzed with the Mann-Whitney U test. 48 hours post operatively all mice in all groups were paralyzed in both hind limbs. Gradual improvement was observed in all groups. At week 3 there was a significant difference between the mean scores of functional tests for both treated groups (A and B) compared with the mean scores of the control group. Statistically significant difference (p&lt;0,05) was observed in 5 out of 7 tests for group A and in 3 out of 7 tests for group B. Same difference between Group A mice and control group mice was observed by 5 weeks, while group B had no statistically significant difference. No animal in any of the groups had a complete recovery 5 weeks postoperatively. Spinal cord in control group mice showed a gradually increase of fibroblastic infiltration until 5 week which entirely separated the two ends of the cord. In group A and group B mice a significant decrease of fibroblastic infiltration was observed at week 5 compared with week 3. Macrophage aggregations were evident at weeks 1 and 5 but not at week 3 in all groups. In conclusion our results indicate that light density bone marrow transplanted cells or G-CSF treatment can accelerate spinal cord injured mice recovery. It is possible that this is associated with a decrease in fibroblastic infiltration of spinal cord. Macrophage aggregation may also play an important role in the mechanism of recovery in mice, while in rats a different reaction including cavitation and delayed demyelination prohibits neurological recovery.
