The use of transforaminal percutaneous endoscopic discectomy for the treatment of far-lateral lumbar disc herniations has been applied mostly in adults. However, transforaminal percutaneous endoscopic discectomy in children has probably been rarely documented. The aim of this study was to assess the efficacy of transforaminal percutaneous endoscopic discectomy in the treatment of far-lateral lumbar disc herniations in children. ⋯ Transforaminal percutaneous endoscopic discectomy achieved satisfactory results for children with far-lateral lumbar disc herniations.

Traumatic injuries to the cervical spine are frequently accompanied by cervical spinal cord injuries-often necessitating tracheostomy. The purpose of this study was to evaluate patient characteristics and outcomes after undergoing anterior cervical spine fusion (ACSF) with tracheostomy. ⋯ IV; retrospective case series.

Our aim was to investigate the biological effects of bone morphogenic protein 2 (BMP2) on the differentiation of bone marrow mesenchymal stem cells (BMSCs) into chondrocyte-like cells in platelet-rich plasma (PRP) gel in vitro. In addition, the effectiveness of BMP2-transduced BMSCs in combined with PRP gel to repair the degenerated intervertebral disc in a rabbit model was also evaluated. Previous studies have shown that tissue engineering provides many promising advantages to treating disc degeneration and may reverse the pathological process of disc degeneration. ⋯ BMP2-transduced BMSCs can maintain the chondrocyte-like phenotype in PRP gel in vitro, and the combined use of these two agents can significantly promote repair of the degenerated discs in vivo.

The purpose of this study was to determine the outcomes in patients treated with robotically assisted patello-femoral arthroplasty (PFA). ⋯ The early retrospective data for robotically-assisted PFA show encouraging results. Advantages of this technique include a smaller incision, faster rehabilitation, preservation of bone stock, and implantation without malalignment.
