Clinical Outcomes of Minimally Invasive Versus Open TLIF: A Propensity-Matched Cohort Study.

In this study, we compare intermediate-term outcomes in minimally invasive surgical transforaminal lumbar interbody fusion (MIS TLIF) to open TLIF. Sixty-four patients who underwent 1- to 2-level MIS TLIF with baseline, 1-, and 2-year outcome measures were identified. These were propensity-matched to a cohort of open TLIF patients based on age, body mass index, sex, smoking status, workers' compensation status, and preoperative outcome measures.

Perioperative complications in revision anterior lumbar spine surgery: incidence and risk factors.

Study Design: This is a retrospective review of 129 consecutive anterior lumbar revision surgeries in 108 patients. It is a single-center, multi-surgeon study.

Objective: To determine occurrence rates and risk factors for perioperative complications in revision anterior lumbar fusion surgery.

Impaction allografting for femoral component revision: clinical update.

The technique of cancellous impaction allografting with cement aims to reconstitute a bone-deficient proximal femur while also gaining stable fixation of the femoral prosthesis. Some reports of this technique imply it is a system, requiring not just an exacting surgical method, but also a particular implant design, the polished, double-tapered stem. Other series consider it a surgical technique, and have varied the femoral component design, the method of graft delivery, and other elements of the procedure.

Endogenous cortisol production in response to knee arthroscopy and total knee arthroplasty.

Background: There is controversy about whether patients who take exogenous glucocorticoids, such as prednisone, require supplemental (exogenous) glucocorticoids in order to meet the physiological demands of surgery. In this study, we sought to define the magnitude of the surgical stress response in normal patients undergoing major and minor elective orthopaedic surgery.

Methods: A prospective, observational study of thirty patients who had not taken exogenous glucocorticoids and who underwent either elective knee arthroscopy or elective unilateral total knee arthroplasty was performed.
