A retrospective review.
To quantify the exact impact of non-insulin-dependent diabetes mellitus (NIDDM) on operative complications and additional surgeries associated with spinal deformity surgery.
There are many references supporting diabetes mellitus (DM) as one of the major risk factors for perioperative complications in spinal surgery. However, the results vary depending on the type of DM, suggesting that insulin-dependent DM causes more complications than NIDDM, which is far more prevalent in the adult population with spinal deformity.
Among 5119 adult patients (older than 40 yr) with deformities, 23 patients with NIDDM and 23 control (group C) patients with a minimum 2-year follow-up were selected. Both groups were matched for age at surgery, sex, body mass index, number of comorbidities, smoking history, current and prior fusion levels, estimated blood loss, and the amount of transfusion. Pre- and final Scoliosis Research Society (SRS) scores and Oswestry Disability Index (ODI), number of perioperative complications, and additional surgeries were compared. Within the group with NIDDM, patients with (+) or without (-) complications were compared in terms of postoperative glucose control.
There were no significant differences in the number of major or minor complications or additional surgeries between the 2 groups. There was no significant difference in postoperative glucose control with the NIDDM group (+) and (-). Group C reported significantly improved scores at final follow-up in all SRS domains and ODI. The group with NIDDM reported improvement in all domains except for the mental health and pain domains. However, there were no significant differences between the group with NIDDM and group C in terms of SRS and ODI scores preoperatively and postoperatively.
Contrary to traditional thinking, properly selected NIDDM was not a significant risk factor for perioperative complications or additional surgeries in adult patients with spinal deformities.

    ABSTRACT: An estimated 285 million adults (aged 20-79 years) worldwide were diagnosed to have diabetes mellitus (DM) in 2010, and this number is projected to grow to 439 million adults by the year 2030. Orthopaedic surgeons, regardless of their subspecialty interest, will encounter patients with DM during their career since this epidemic involves both developed and emerging countries. Diabetes results in complications affecting multiple organ systems, potentially resulting in adverse outcomes after orthopaedic surgery. The purpose of this review is to discuss the pathophysiology of DM and its potential for impacting orthopaedic surgery patients. Diabetes adversely affects the outcome of all orthopaedic surgery subspecialties including foot and ankle, upper extremity, adult reconstructive, pediatrics, spine surgery and sports medicine. Poorly controlled diabetes negatively impacts bone, soft tissue, ligament and tendon healing. It is the complications of diabetes such as neuropathy, peripheral artery disease, and end stage renal disease which contributes to adverse outcomes. Well controlled diabetic patients without comorbidities have similar outcomes to patients without diabetes. Orthopaedic surgeons should utilize consultants who will assist in inpatient glycemic management as well as optimizing long term glycemic control.
