Intervertebral disc degeneration often requires bony spinal fusion for long-term relief. Current arthrodesis procedures use bone grafts from autogenous bone, allogenic backed bone, or synthetic materials. Autogenous bone grafts can result in donor site morbidity and pain at the donor site, while allogenic backed bone and synthetic materials have variable effectiveness. Given these limitations, ...

Whilst bony luno-triquetral coalitions are known to be asymptomatic, fibro-cartilage unions can cause ulnar-sided wrist pain. The purpose is to present the rare case of painful pseudarthrosis after traumatic disruption of an incomplete luno-triquetral coalition. Recommendations for proper diagnosis and treatment options will be discussed. The case of a 35-year-old male patient is reported, wher...

The acquisition of bony fusion is a complex task. Attention paid to the details presented here may improve fusion rates and patient outcomes. We have much to learn. We should focus on the details of the present and on the possibilities of the future to guide our surgical decision-making process. Indeed, "traumatized bone, whether disrupted via an overt act of trauma or via surgical intervention...

UNLABELLED In the present case of postoperative lumbar spinal stenosis after non-instrumented intertransverse fusion with granules of hydroxyapatite (HA), bone union was not completed and the patient felt the recurrence of his symptoms within two years. We performed re-decompression with fusion, and in hematoxylin and eosin staining of HA granulation harvested during revision surgery, fibrous t...

A 54-year-old female with neurofibromatosis type 1 presented with progressing truncal shift owing to spinal deformity. On plain radiograph, the Cobb angle was 54 degree in coronal plane. Radiological examinations showed severe dystrophic change with dysplastic pedicles, bony scalloping, neural foraminal widening from dural ectasia. The patient underwent deformity correction and reconstruction s...

Primary sarcomas of the thumb metacarpal are rare malignant lesions. Surgical treatment involves amputation versus tumor resection with thumb reconstruction. If complete tumor resection is possible, thumb preservation may be considered, as the thumb is vital to hand function. Following tumor resection, previous reports have described graft reconstruction with fusion to the trapezium or scaphoid...

INTRODUCTION: Direct lateral interbody fusion (DLIF) is less invasive than traditional methods, such as anterior lumbar interbody fusion (ALIF). While the direct lateral approach is safer for a variety of clinical reasons, immobilization of motion segments is crucial for complete bony union, regardless of approach. Therefore, biomechanical assessment is necessary to determine if the DLIF approa...

BACKGROUND Craniospinal junction tumors are rare but severe lesions. Surgical stabilization has been established to be an ideal treatment for upper cervical tumor pathology. The purpose of this study was to evaluate the effect of a screw-rod system for occipitocervical fusion. METHODS A total of 24 cases with C1 and C2 cervical tumor underwent occipitocervical fusion with Vertex screw-rod int...

Purpose: This study aimed to investigate radiographic outcomes after posterior spinal fusion (PSF) for pediatric patients younger than 10 years with upper cervical disorders. Methods: Thirteen patients (mean age at surgery, 5.9 years; range, 1 to 9 years) who underwent PSF with a minimum of 2 years of follow-up (mean, 5.8 years) were included. Diagnoses were atlanto-axial instability due to con...
