With this report we decided to present the initial experience with the use of cement augmented screws in Cotrel-Dubousset fixation in cases of patients with degenerative spines in combination with severe osteoporosis.
We present two patients who underwent treatment at UMHAT "Sv. Georgi ”, Plovdiv. The first is a 75-year-old woman who underwent right hip arthroplasty in 2002 with a Muller prosthesis. 14 years later (in 2016) due to implant ablation, a revision of the joint with a cementless, revision modular endoprosthesis of Metrimed was performed. In 2022, due to secondary degenerative scoliosis, the patient began to complain of pain in the lumbar spine, which required decompression and posterior fixation with cement augmented screws.
The second patient was a 72 years old female and in September 2021 suffered an osteoporotic fracture at L4 level. Balloon kyphoplasty was performed at the same level. However, due to leakage of cement into the vertebral canal, it was necessary to decompress the canal and apply again the mentioned fixation system.
The visual analog scale (VAS) was used to assess the effect of response to therapy. Both patients had no symptoms of nerve compression.
Fenestrated screws were used in both cases.
