ABSTRACT
Objective: To assess the mid-term effecitveness of femoroacetabular impingement (FAI) treated by surgical hip dislocation. Methods: Between April 2014 and August 2015, 15 patients (16 hips) with FAI were enrolled in the study and treated with surgical hip dislocation. There were 12 males and 3 females with an average age of 36.6 years (range, 22-59 years). Among them, 14 cases involved in unilateral hip and 1 in bilateral hips. The mean disease duration was 28 months (range, 4-120 months). Preoperative visual analogue scale (VAS) score and Harris hip score were 7.9±1.0 and 44.1±9.3, respectively. Results: All incisions healed by first intention. There was no main complication, such as vessel and nerve injuries and infection. All 15 patients were followed up 30-46 months (mean, 39.5 months). The VAS score was 2.5±1.6 at 3 months and 0.5±0.7 at last follow-up. The Harris score was 85.5±4.4 at 3 months and 95.6±3.9 at last follow-up. There were significant differences in two scores between pre- and post-operation and between 3 months and last follow-up ( P<0.05). The satisfaction rate of hip function was 93.8% (15/16) at last follow-up. X-ray examination showed that there was no sign of impingment at the femoral head and neck and acetabulum forming site of the affected hip joint, and no complication such as loosening of internal fixator, nonunion of osteotomy, avascular necrosis of femoral head, and heterotopic ossification occurred during follow-up. Conclusion: The surgical hip dislocation is a safe and effective way to treat FAI in the mid-term follow-up, which can repair torn labrum and trim acetabulum and femoral neck.
ABSTRACT
Objective: To assess the mid-term effectiveness of arthroscopic surgery in treatment of femoroacetabular impingement (FAI).
ABSTRACT
The cortexes were obtained from new-born rats and dissociated to single cells by triturating. The cells were cultured in neural stem cell (NSC) culture medium (DMEM supplemented with bFGF, EGF and B27) and formed primary neurospheres after 7 days. Single cells dissociated from neurosphere were cultured in 96-well plates and formed single-cell cloning neurosphere 7 days later. The primary and single-cell cloning neurospheres were both positive for the immunofluorescent staining of nestin and were identified as NSC. It was proved that NSC can be expanded in vitro and provide seed cells for neural tissue engineering.
