Compared with other approaches, anterior lumbar interbody fusion (ALIF) is believed to be more effective at restoring segmental lordosis and reducing risks of adjacent-segment disease. It remains controversial, however, whether ALIF improves global lumbar lordosis or influences pelvic parameters, possibly because of the heterogeneity of implants and levels studied. ⋯ Stand-alone mini-ALIF with anterior plate fixation for L5-S1 can change pelvic parameters while improving global and segmental lumbar lordosis. The procedure resulted in a fusion rate of 96% and comparable improvements in ODI to other studies.

Pre-existing comorbid psychiatric mood disorders are a known risk factor for impaired health-related quality of life and poor long-term outcomes after spine surgery. ⋯ Patients with preoperative psychiatric mood disorders undergoing elective cervical surgery had worse NDI scores and received more opioid prescriptions, despite similar VAS scores as those without mood disorders. Lumbar surgery patients with mood disorders were demographically different than those without mood disorders and had worse pain before and after surgery, though ODI scores were not different. Tobacco use was the sole contributor to postoperative VAS pain scores. This information can be useful in counseling patients with mood disorders before elective spinal surgery.

Laminoplasty is a common surgical method used to treat patients with cervical ossification of the posterior longitudinal ligament (OPLL). Although laminoplasty is preferred over traditional laminectomy, the factors affecting the complications and outcomes are unclear. Recently, sagittal balance indexes have been revealed to be predictors of clinical outcomes in patients with cervical degenerative diseases, but their relationships with laminoplasty-treated OPLL outcomes remains unknown. ⋯ Preoperative cervical sagittal balance indexes are related to the outcomes of OPLL patients after laminoplasty. Patients with high preoperative CGH-C7 SVA levels have a high probability of developing sagittal imbalances and neurological symptoms of the cervical spine, and this measurement can be used as a predictor of outcomes in laminoplasty-treated cervical OPLL patients.

Lumbar laminectomy and discectomy surgeries are among the most common procedures performed in the United States, and often take place at academic teaching hospitals, involving the care of resident physicians. While academic institutions are critical for the maturation of the next generation of attending surgeons, concerns have been raised regarding the quality of resident-involved care. There is conflicting evidence regarding the effects of resident participation in teaching hospitals on spine surgery patient outcomes. As the volume of lumbar laminectomy and discectomy increases, it is imperative to determine how academic status impacts clinical and economic outcomes. ⋯ Elective lumbar laminectomy and discectomy for degenerative lumbar conditions at teaching hospitals is associated with higher costs, but decreased length of stay and no difference in readmission rates at 30- and 90-days postoperatively compared to nonteaching hospitals. Teaching hospitals had a decreased risk of return to the operating room at 30 days, 90 days and 1 year postoperatively. Our findings might serve as an impetus for other states or regions to compare outcomes at teaching and nonteaching sites.

Open-door laminoplasty often results in postoperative complications such as loss of cervical lordosis, limitations of cervical motion, and axial symptoms. However, current modified laminoplasty techniques such as muscle-sparing type or spinous process splitting technique are not as effective as expected. ⋯ C3 laminectomy combined with modified unilateral laminoplasty is effective for treating patients with multilevel cord compression. This modified technique reconstructs the midline structures and may lead to improved alignment and less axial pain.
