Distraction osteogenesis after post-traumatic segmental bone loss of the tibia is a complex and time-consuming procedure that is often complicated due to prolonged consolidation or complete insufficiency of the regenerate. The aim of this feasibility study was to investigate the potential of bone marrow aspiration concentrate (BMAC) for percutaneous regenerate augmentation to accelerate bony consolidation of the regenerate. Eight patients (age 22-64) with an average posttraumatic bone defect of 82.4 mm and concomitant risk factors (nicotine abuse, soft-tissue defects, obesity and/or circulatory disorders) were treated with a modified Ilizarov external frame using an intramedullary cable transportation system. At the end of the distraction phase, each patient was treated with a percutaneously injection of autologous BMAC into the centre of the regenerate. The concentration factor was analysed using flow cytometry. The mean follow up after frame removal was 10 (4-15) months. With a mean healing index (HI) of 36.9 d/cm, bony consolidation of the regenerate was achieved in all eight cases. The mean concentration factor of the bone marrow aspirate was 4.6 (SD 1.23). No further operations concerning the regenerate were needed and no adverse effects were observed with the BMAC procedure. This procedure can be used for augmentation of the regenerate in cases of segmental bone transport. Further studies with a larger number of patients and control groups are needed to evaluate a possible higher success rate and accelerating effects on regenerate healing.

Abstract Background The Ilizarov segmental bone transport technique can be applied in the reconstruction of the bone defects with less invasive fashion and more versatility compared to other methods, while most studies were focused on the lower extremity. The purpose of this study was to evaluate the effectiveness of the Ilizarov segmental bone transport technique in the treatment of diaphyseal forearm bone defects caused by infection. Methods This study included 12 patients with diaphyseal forearm bone defects caused by infection, who underwent bone transport procedures using the monolateral external fixator at our institution from January 2010 to January 2018, including 10 males and 2 females with a mean age of 39 years (range 23–57 years). Patient’s demographic data and clinical outcomes at least two years follow-up after removing the external fixator were collected and retrospectively analyzed. The functional results were evaluated by the questionnaire of Disability of Arm, Shoulder and Hand (DASH) and the modified Mayo wrist score (MWS) at the final follow-up. Results There were 10 radii and 2 ulnae bone transport procedures collected. The average defect size was 5.1 cm (4-6.5 cm). All patients were successfully followed up with a mean period of 28.2 months (24 to 36 months) and achieved infection-free union. There was no recurrence of infection observed. The mean external fixation time was 232.6 days (182 to 276 days), and the mean external fixation index was 46.3 days/cm (40.9 to 61.8 days/cm). The mean DASH score was 30.6(18 to 49) preoperative, while 13.8 (5 to 26) at the final follow-up. The average modified MWS improved from 68.8 (55 to 80) pre-operatively to 83.8 (65 to 90) at the final follow-up. All the differences between the preoperative and final scores were statistically significant (p < 0.05). Almost all the patients achieved satisfactory clinical outcomes and were able to perform activities of daily living. Conclusions Ilizarov segmental bone transport technique is an alternative and effective method for the treatment of diaphyseal forearm bone defects caused by infection, and this method acquired satisfactory clinical outcomes.

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 Abstract 4544 Background The importance of bone marrow aspiration and biopsy in the evaluation of hematopoietic and non-hematopoietic disorders is well established. Recently, a new FDA-cleared battery powered bone marrow biopsy system was developed to allow operators access to the bone marrow space quickly and efficiently. Aims The first aim of this study was to evaluate the quality of core specimens using the new powered device compared to specimens obtained using the traditional manual technique in a swine model. The second aim was to evaluate the safety and efficacy of the device in patients presenting for outpatient hematology clinic visits. Materials and Methods For the pre-clinical evaluation of the device, three anesthetized pigs were used for the study. The powered device (OnControl, Vidacare Corporation, San Antonio, TX, USA) was comprised of a battery powered driver and needle set. The manual device used was a T-Handle Jamshidi bone marrow biopsy needle (Cardinal Health, Dublin, OH, USA). Core biopsy samples obtained were assessed for length and sample quality and then submitted for analysis to a pathologist blinded to the device used. The clinical evaluation of the device was conducted in accordance with practice guidelines and directions for use. Data collection included insertion success, time from insertion to removal, specimen quality, operator satisfaction with control/function of the device and overall operator satisfaction based on a scoring system (0-5; 0=totally unacceptable, 5=outstanding). Results Twenty six samples were collected from the swine model (19 samples using the powered device and 9 using the manual technique). No cellular artifact or thermal damage was reported in any of the samples obtained. The mean lengths for samples obtained using the powered and manual techniques were respectively 19.4mm±1.6mm and 18.6mm±5.3mm. For the clinical evaluation of the device, 16 patients were recruited from 2 centers. Mean insertion time was 11.25±3.39 seconds and mean time from needle contact with skin to needle removal was 38.5±13.94 seconds. No complications were reported. Five operators rated the overall use of the device as outstanding in 75% of cases. Conclusions In this study, the manual and powered samples were equivalent in specimen quality. The powered device however, captured longer biopsies when compared to the manual technique. In the patients evaluated, the device was easy to use as well as being safe and effective. The mean procedural time was significantly faster than previously reported with a manual technique. A randomized study of the powered device compared to the manual technique is underway.

Abstract Abstract 1529 Introduction: The importance of bone marrow aspiration and biopsy in the evaluation of hematopoietic and non-hematopoietic disorders is well established. However, this technique is associated with morbidity and mortality risks.1 Recently, a battery-powered bone marrow biopsy system was developed to allow operators to safely, quickly and efficiently access the marrow space. We previously evaluated this device in swine models and in patients needing routine hematology outpatient evaluation.2 In the current study we compared the powered device to the traditional manual technique by relatively assessing pain scores, procedure times, biopsy capture rates, quality of material retrieved, safety and operator satisfaction. Methods: Two large academic medical centers participated in this trial (San Antonio, TX and Madrid, Spain). The study protocol was approved by each center's institutional review board. Adult patients requiring bone marrow biopsies were considered for the study. Following informed consent, patients were randomized to have procedures using a manual biopsy device (T-handle Jamshidi bone marrow biopsy and aspiration set, Cardinal Health, Dublin, OH) or the Powered device (OnControl 11 gauge/102mm Bone Marrow Biopsy System, Vidacare Corporation, Shavano Park, TX). After infiltration of the skin and medullary bone with local anesthesia, a visual analog scale (VAS) pain score was recorded immediately following skin puncture and once again at the end of the procedure for each patient. Procedure time was measured from skin puncture to core specimen ejection from the needle. Pathologic assessment of 30 randomized samples was carried out. Operator satisfaction with devices was measured on a scale of 0–10, with 10 as the highest rating. Statistics were calculated using t-test and chi-square, with an alpha-level of 0.05. Results: Five operators from 2 sites enrolled 50 patients (Powered, n=25; Manual, n=25). Of those patients, 58% were male and 42% were female; and had a mean age of 56.0±18.0 years. The mean height was 167.5 ± 10.5cm and the mean weight was 78.7 ± 22.7kg. Forty percent were lymphoma patients—the largest diagnostic group. Between patient groups, there were no significant differences in the means for these variables. See Table below for quantitative results, including pathology analysis. For the pathology qualitative analysis, there was no difference between groups for hemorrhage, clot/particle spicules, or smear spicules. Conclusions: Results of this trial suggest that the use of a Powered bone marrow biopsy device significantly reduces needle insertion pain. While not reflected in the results, overall pain may be better tolerated due to the important difference in procedure time. Moreover, the superior size and overall quality of core specimens retrieved by the Powered device provides more material for pathologic evaluation, thereby increasing diagnostic yield and reducing the need for repeat procedures. Cohesiveness of the medullary bone sampled was comparable for both techniques; however, the Powered system was less likely to recover non-hematopoietic tissue (e.g. cortical bone and soft tissue). Artifact was slightly more common with the Powered device (aspiration, hemorrhage and crush) but this did not impact on the diagnostic quality of the sample. No differences in safety data were noted for either technique and operator satisfaction favored the Powered device. 1. Bain BJ. Bone marrow biopsy morbidity and mortality.

Given the limited therapeutic options for refractory dilated cardiomyopathy we decided to perform a phase I clinical trial using bone marrow derived mononuclear cells in patients with functional classes II and IV of the NYHA. Inclusion criteria required EF% (Simpson) <35%, VO2 max < 16 kg.ml /min and signed informed consent. After enrollment patients were subject to the following exams at baseline, 2 and 6 months after cell therapy: 12 lead ECG and 24hs holter, echocardiography, chest X-ray, blood biochemistry, BNP, ergoespirometry, MRI and Minnesota Questionnaire. Patients were subject to bone marrow aspiration (80–100 mL) under sedation and local anesthesia and mononuclear cells were obtained after Ficoll gradient centrifugation. A mean of 198 million cells diluted in 20 ml of saline were slowly delivered through catheterization in the coronary arteries (10 ml in LAD, 5 ml in RC, 5 ml in CX). After the procedure patients remained hospitalized for 48hs. We report the results of the first 22 patients that completed the follow-up period. No adverse effects related to the procedure were observed, nor were arrhythmias detected after cell delivery. Four patients died during follow up. For the 18 patients that completed follow up, there was a significant improvement in NYHA functional class and quality of life at 2 and 6 months (p<0.03 and p< 0.007, respectively). There were no statistically significant changes in EF% (18.6%, 18.6% and 19%), EDV (360, 371, 386 ml) or ESV (295, 308, 314 ml) at baseline, 2 and 6 months respectively as measured by MRI. Maximal oxygen consumption showed as significant increase after cell therapy (12.5, 15.3, 16.8 ml/kg.min), and the number of patients with oxygen consumption below the threshold for cardiac transplantation decrease from 75% at baseline to 25% six months after cell therapy. BNP levels were not significantly altered (650, 475, 530 pg/ml). When observed individually, 4 of the 17 patients examined showed an increase in EF% by MRI ≥5%, 7 did not change EF% and 3 decreased EF% by ≥5%. In conclusion, the procedure is safe and feasible but further studies are necessary to test for efficacy.

Abstract The importance of bone marrow examination in the evaluation of leukemia, multiple myeloma, anemia, pancytopenia, and other disorders is well established. The objective for this study was to evaluate the ability of a powered bone marrow aspiration device to penetrate the intraosseous medullary space of the iliac crest, and to aspirate bone marrow samples for the ultimate purpose of diagnosing disease and monitoring the course of disease and medical therapy. The device was used to obtain bone marrow samples in accordance with accepted practice guidelines and device’s directions for use. Among other data, insertion success, time to insertion, and complications were recorded. Patient pain levels were rated from 0 to 10 (10=extreme pain). Device operators rated the use of the device from 0 to 10 (10=outstanding). There were 55 patients in the study from three centers. Successful insertion and aspiration of bone marrow samples were achieved in 54 of the 55 patients (98.1%). Mean insertion time was 4.9±3.0 seconds; significantly faster than the 7.3 minutes reported by Kuball et al* (one-sample t-test, p<0.001). There were no complications. The mean insertion pain score was 2.5±2.2 and the mean aspiration pain score was 3.7±2.5. On a scale of 0 to 10, the six operators rated the ease of use of the device at a mean score of 8.3±1.7. Findings suggest that the powered aspiration device is safe and effective for bone marrow aspirations.

Background: Pancytopenia is consequence of many haematological condition with an extensive differential diagnosis. A prompt intervention is required to avoid complications. The severity and the underlying pathology determines the management and prognosis. Present study was conducted to assess the etiology, clinical profile and bone marrow morphology of pancytopenia.Methods: A prospective study was carried out among 50 consecutive patients with pancytopenia. Blood samples of the patients were analyzed for complete blood count and peripheral smear along with presence and absence of immature cells and abnormal cells. In bone marrow examination, morphology of all cells lineage, cellularity, parasite and abnormal cells were scrutinized. Trephine biopsy was done if indicated. Special investigations were done to confirm the diagnosis.Results: Among the 50 cases studied, age of the patients ranged from 1 to 70 years with a slight male predominance. Most common age group 11-20 years. Most of the patients presented with generalized weakness and fever. The commonest physical finding was pallor, followed by splenomegaly and hepatomegaly. The commonest marrow finding was hyper cellularity with megaloblastic erythropoiesis. The commonest cause for pancytopenia was megaloblastic anemia.Conclusions: The present study concludes that hematological investigations along with other supportive tests are helpful to diagnose or to rule out the causes of pancytopenia. Megaloblastic anemia is commonest cause of pancytopenia in most Indian and subcontinent studies. Substantial number of patients had reversible etiology. Hence complete work up including clinical details with hematological examination along with bone marrow study will lead to early and proper diagnosis and management.
