Background:
The anterior cervical discectomy and fusion (ACDF) is the gold standard in the treatment of cervical compression pathology and the titanium cage for fusion represents the most used procedure at an institutional level. A technique using fibular autograft has been described, with good results, lower morbidity and lower cost.
Objective:
To compare the rate of fusion, subsidence and functional clinical results after discectomy with titanium cage and fibular autograft.
Material And Methods:
A clinical trial with follow-up at 3 and 6 months was carried out in patients diagnosed with cervical spondylosis, candidates for ACDF. 2 groups were formed: fibular autograft and titanium cage. Pre and post functional evaluation using the cervical disability score was made, as well as radiographic fusion and subsidence evaluation. Descriptive statistics, Fisher's exact test, t-test and ANOVA were obtained, establishing p < 0.05.
Results:
A sample of 20 patients with an average age of 56 years was obtained, finding a fusion rate of 90% for fibular autograft and 30% for titanium (p = 0.02) at 3 months. 10% of patients with fibular autograft presented subsidence and 70% with titanium cage at 3 and 6 months (p = 0.02). In the functional results was not found difference between both procedures (p = 0.874).
Conclusions:
The use of autologous fibular graft offers a better rate of fusion and subsidence compared to the titanium cage, as well as similar functional results at 3 months of follow-up. It represents an excellent treatment option for cervical spondylosis.

Bone as Supporting Connective Tissue
Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts— that give the...

The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
