Increasing Fusion Rate Between 1 and 2 Years After Instrumented Posterolateral Spinal Fusion and the Role of Bone Grafting

Study Design. Two-year clinical and radiographic follow-up of a double-blind, multicenter, randomized, intra-patient controlled, non-inferiority trial comparing a bone graft substitute (AttraX® Putty) with autograft in instrumented posterolateral fusion (PLF) surgery. Objectives. The aim of this study was to compare PLF rates between 1 and 2 years of follow-up and between graft types, and to explore the role of bone grafting based on the location of the PLF mass. Summary of Background Data. There are indications that bony fusion proceeds over time, but it is unknown to what extent this can be related to bone grafting. Methods. A total of 100 adult patients underwent a primary, single- or multilevel, thoracolumbar PLF. After instrumentation and preparation for grafting, the randomized allocation side of AttraX® Putty was disclosed. The contralateral posterolateral gutters were grafted with autograft. At 1-year follow-up, and in case of no fusion at 2 years, the fusion status of both sides of each segment was blindly assessed on CT scans. Intertransverse and facet fusion were scored separately. Difference in fusion rates after 1 and 2 years and between grafts were analyzed with a Generalized Estimating Equations (GEE) model (P

This is a case of radicular cyst associated with tooth 22 of a 63-year-old woman, with complaint of increased gingival volume. The sensitivity test was negative and the periapical radiography showed a radiopaque lesion associated with the root of the tooth, circumscribed by a radiolucent lesion. An access and placement of paste of calcium hydroxide with olive oil was performed and a CT scan was requested. It wasn ’t possible to remove the lesion that was associated with the root during the intraoperative period, choosing the tooth extraction, curettage of the lesion, a bone graft, and the placement of a membrane for ...

Study Design: This is a prospective, stratified randomized, multicenter, 4-year follow-up study. Objective: The authors aimed to evaluate the long-term clinical efficacy and safety of CaO-SiO2-P2O5-B2O3 glass ceramics (BGS-7) spacers in 1-level posterior lumbar interbody fusion (PLIF) at a 4-year follow-up. Summary of Background Data: According to 1-year follow-up results, BGS-7 spacer showed similar fusion rates and clinical outcomes compared with titanium cage. A long-term follow-up study beyond 2 years is necessary to investigate the status of intervertebral bone graft volumes. Moreover, longer follow-up is mand...

AbstractPurposeThe aim of this study was to evaluate the efficacy of a new minimally invasive surgical technique for the reconstruction of the medial patellofemoral ligament (MPFL) with fascia lata allograft at 60-month minimum follow-up.MethodsNineteen consecutive patients with chronic recurrent patellar dislocation were treated with MPFL reconstruction (53% isolate procedure, 47% in combination with other treatments). Seventeen patients (11 males/6 females) were available at 60-month follow-up and were clinically evaluated with validated scores. New episodes of patellar dislocation were considered failures. Radiographic ...

CONCLUSIONS Our study confirmed that by the minimally invasive technique of bone graft harvesting adequate amount of tissue to treat defect fractures and non-unions can be harvested. Spongioplasty using grafts harvested in this manner is effective, with a minimum percentage of non-unions. The advantage of this technique is the proximity of the harvest site and the operative field and low level of pain. The minimally invasive graft harvesting represents a technique with a low risk of postoperative and late complications. Key words: bone graft, autografts, minimally invasive surgery, ilium, pain.

CONCLUSION: The proposed classification mainly relies on intraoperative findings which were confirmed by preoperative imaging in 154 cases out of 160 (96.25%); however, meticulous preoperative planning based on X‑ray radiographs must be carried out. In addition, a CT scan must be performed whenever type III or type IV defects are anticipated. Compared to the existing classification systems, we can state that our classification system is practicable and pragmatic and simplifies the assessment of bone defects.

This study aimed to analyze cervical alignment after single-level ACCF using autologous bone graft without spinal instrumentation for CPS compared with that for CDD.MethodsSix patients underwent single-level ACCF using autologous bone graft without spinal instrumentation for CPS. The control group included 18 age-matched patients who underwent single-level ACCF using autologous bone graft for CDD without spinal instrumentation for the same duration. Cervical and lateral plain radiographs and computed tomography scans were taken. The Frankel classification was used to assess the neurological status preoperatively, postopera...

Conclusion: Our data showed that the new allograft cage is superior to the PEEK cage in providing a high fusion rate and fewer complications after 1-level and 2-level ACDF procedures. It may represent an excellent alternative to other cages.

CONCLUSIONS: Nasal floor elevation proved to be a reliable method for dental implants insertion on the anterior atrophic maxilla when bone height reconstruction was necessary. The use of bovine bone substitutes for nasal cavity augmentation showed predictable results as well as simultaneous implant placement. PMID: 31473714 [PubMed]
