Intramedullary Nail Fixation with Autologous Bone Marrow Transplantation in an Incomplete Atypical Femoral Fracture Patient: Use of Bone Marrow Extracted from the Hollow Reamer.

ABSTRACT: The present report describes an incomplete atypical femoral fracture (AFF) patient who underwent simultaneous autogenous bone transplantation to the resected fracture region during intramedullary nail fixation. A 73-year-old female with a history of multiple myeloma had been undergoing treatment with intravenous drip injections of Zoledronic Acid. She was introduced to our department due to the left lateral thigh pain, with no trauma incidence. An anteroposterior radiograph showed a transverse thin fracture line with localized periosteal and endosteal thickening, which is compatible with subtrochanteric incomplete AFF. A biochemical investigation revealed the existence of severely suppressed bone turnover. She underwent intramedullary nail fixation for fear of a complete fracture. After the fixation, the cortical bone at the fracture region was excised as a wedge-shaped block, and bone marrow extracted from the hollow reamer was simultaneously transplanted to the resected fracture region. Histological examination showed few bone formation features at the fracture line in the excised lateral cortical bone. At 7 months after surgery, radiographs demonstrated complete bone repair, and no clinical problems were observed two years postoperatively. To the best of our knowledge, this is the first report in which autogenous bone marrow transplantation, noninvasive to the iliac crest, was performed in an incomplete AFF patient. We believe that this low invasive procedure can be a useful technique for AFF treatment.

Project description:ObjectiveTo explore the clinical effect of antibiotic artificial bone implantation and external fixation in the treatment of infection after intramedullary nail fixation.MethodsWe retrospectively reviewed the clinical data of patients with infection after intramedullary nail fixation treated from March 2010 to August 2020. There were 27 males and 6 female, aged from 12 to 67 years (average 42.27 years), 18 cases on the left side and 15 cases on the right side. Among them, 20 cases were open fractures with initial injury and 13 cases were closed fractures. All patients were treated with intramedullary nail removal, local debridement, antibiotic artificial bone implantation and external fixation. Because of bone defects, 19 patients underwent secondary autologous cancellous bone grafting after infection control. Postoperative wound healing, related inflammatory indicators, fixation time, and bone healing time were recorded and followed up.ResultsThe 33 patients were followed up with period of 10 ~ 98 months (average 62.7 months). One patients failed to control the infection effectively after treatment, so received antibiotics artificial bone implantation again. Two patients also received antibiotic artificial bone implants again due to the recurrence of the infection. After treatment, infection was controlled and the fracture healed well. One patient received vacuum sealing drainage (VSD) due to persistent postoperative exudation, and five patients were also cured successfully after continuous dressing. Two patients had sinus tract after surgery, and the wound was cured by continuous dressing change. Nineteen patients received autogenous iliac bone grafts for healing due to bone defects ranging from 3 to 6.5 cm (average 4.15 cm) after infection control. The external fixation time of 33 patients ranged from 4 to 16 months (average 7.79 months), the bone healing time ranged from 4 to 13 months (average 6.67 months), and the related inflammatory indexes returned to normal within 2-8 weeks (average 4.48 weeks).ConclusionAntibiotic artificial bone implantation and external fixation is an effective method for the treatment of infection after intramedullary nail fixation.

Project description:BackgroundWe introduced a new surgical method of percutaneous hollow perforated screw (HPS) fixation with concomitant bone-cement injection for the treatment of femoral neck metastasis and evaluated its efficacy for the palliative treatment of patients with advanced cancer.MethodsThe study included 87 patients (39 men and 48 women; mean age [and standard deviation], 64.2 ± 10.2 years; mean body mass index, 24.3 ± 3.2 kg/m2) who underwent percutaneous HPS fixation and cementoplasty (mean cement amount, 19.8 ± 8.3 mL) for the treatment of unilateral or bilateral femoral neck metastasis (total, 95 sites). Anesthesia type, operative time, operative blood loss, pain score changes (according to a visual analog scale [VAS]), walking status, and complications were assessed. The mean duration of follow-up was 10.1 ± 10.8 months (range, 2 to 43 months).ResultsThe majority of procedures were performed with local (3 patients) or spinal (72 patients) anesthesia (total, 75 patients; 86.2%). The mean operative time was 35.9 minutes, and the mean operative blood loss was 97.0 mL. The VAS score for pain improved significantly, from 6.8 ± 2.8 preoperatively to 2.8 ± 2.3 and 2.9 ± 2.8 at 1 and 6 weeks postoperatively (p < 0.001). At 6 weeks postoperatively, 63 (80.8%) of 78 patients were able to walk (with either normal or limping gait, a cane or crutch, or a walker). The prevalence of major local complications (cement leakage into the hip joint, fixation failure) was 10.5% (10 of 95), but major systemic complications (distant cement embolism) were not found.ConclusionsPercutaneous HPS fixation and cementoplasty for the treatment of femoral neck metastasis is a minimally invasive technique that provides effective pain relief and early stabilization. This technique seems to be useful for patients with advanced cancer for whom open surgery would be hazardous.Level of evidenceTherapeutic Level IV.

Project description:BackgroundThere is no consensus regarding the surgical treatment of humeral shaft fracture. The present meta-analysis was performed to compare the efficacy and safety between antegrade intramedullary nailing (IMN) and plating for humeral shaft fracture.MethodsPubMed, MEDLINE, Cochrane Library, EMBASE, Clinical Trails, Ovid, ISI Web of Science, and Chinese databases including WanFang Data, China National Knowledge Infrastructure were searched through March 10, 2019. The Review Manager software was adapted to perform statistical analysis and relative risk (RR) were used for the binary variables, and weighted mean difference and standardized mean difference (SMD) were used to measure the continuous variables. Each variable included its 95% confidence interval (CI).ResultsA total of 15 trials with 839 patients were included in the analysis. There was significant difference between IMN group and plate group in blood loss (SMD = 3.49, 95% CI: 1.19, 5.79, P = .003) and postoperative infections (RR = 3.04, 95% CI: 1.49, 6.24, P = .002). Additionally, significant difference was observed between minimally invasive plate osteosynthesis (MIPO) group and IMN group in nonunion rate (RR = 3.20, 95% CI: 0.12, 0.84, P = .02). Statistical significance was also observed between the open reduction plate fixation group and IMN group in restriction of shoulder and elbow joints results (RR = 0.49, 95% CI: 0.26, 0.96, P < .05). No significant difference was observed for the operation time, American Shoulder and Elbow Surgeons score, nerve injury, delayed union, reoperation in either group.ConclusionIMN may be superior to plate in reducing blood loss and postoperative infections for the treatment of humeral shaft fracture. However, MIPO was superior to IMN group in nonunion and equal to IMN in other parameters. Further research is required and future studies should include analysis of assessments at different stages and follow-up after removal of the implants.
