Does the presence of cervical deformity in patients with baseline mild myelopathy increase operative urgency in adult cervical spinal surgery? A retrospective analysis.

OBJECTIVE: The objective of this study was to assess whether delaying surgical management of cervical deformity (CD) in patients with concomitant mild myelopathy increases the risk of suboptimal outcomes. METHODS: Patients aged ≥ 18 years who had a baseline diagnosis of mild myelopathy with baseline and up to 2 years of postoperative data were assessed. Patients were categorized as having CD (CD+) or not (CD-) at baseline. Patients with symptoms of myelopathy for more than 1 year after the initial visit prior to surgery were considered delayed. Clinical and radiographic data were assessed using means comparison analyses. Multivariate regression analysis assessed correlations between increasing time to surgery and peri- and postoperative outcomes adjusted for baseline age and frailty score. Backstep logistic regression analysis assessed the risk of complications or reoperation, while controlling for baseline T1 slope minus cervical lordosis (TS-CL). RESULTS: One hundred six patients were included (mean age 58.11 ± 11.97 years, 48% female, mean BMI 29.13 ± 6.89). Of the patients with baseline mild myelopathy, 22 (20.8%) were CD- while 84 (79.2%) were CD+. Overall, 9.5% of patients were considered to have delayed surgery. Linear regression revealed that both CD- and CD+ patients were more likely to require reoperation when there was more time between the initial visit and surgical admission (p < 0.001). Additionally, an adjusted logistic regression indicated that CD+ patients who had a greater length of time to surgery had a higher likelihood for major complications (p < 0.001). Conversely, CD+ patients who were operated on within 30 days of the initial visit had a significantly lower risk for a major complication (OR 0.901, 95% CI 0.889-1.105, p = 0.043), and a lower risk for reoperation (OR 0.954, 95% CI 0.877-1.090, p = 0.043), while controlling for the severity of deformity based on baseline TS-CL. CONCLUSIONS: The findings of this study demonstrate that a delay in surgery after the initial visit significantly increases the risk for major complications and reoperation in patients with CD with associated mild baseline myelopathy. Early operative treatment in this patient population may lower the risk of postoperative complications.

Distal Radius Fracture Outcomes After Dorsal Spanning Plate Fixation.

BACKGROUND: Dorsal spanning plate fixation can be used to treat comminuted distal radius fractures not amenable to volar plating. However, there is a relative paucity of outcomes data; so, the aim of this retrospective study was to investigate outcomes and complications after dorsal spanning plate fixation for distal radius fractures. METHODS: Distal radius fractures treated with dorsal spanning plate fixation at a level-1 trauma center were retrospectively identified via Current Procedural Terminology coding and chart review from 2014 to 2019. Patient demographics, fracture pattern characteristics, fixation techniques, and clinical outcomes were all obtained via chart review using the electronic medical record. RESULTS: In all, 43 dorsal plates were identified out of 369 operatively treated distal radius fractures (12%). Of these, 84% were AO type C, 28% were open fractures, and 86% resulted from falls. At the time of dorsal plating, 28% had an additional procedure. One patient had a major complication after surgery, requiring unplanned surgery for a radius nonunion. Average final follow-up occurred 9 weeks after dorsal plate removal, with mean range of motion at the wrist measuring: 36° flexion, 48° extension, 75° pronation, and 63° supination. Finger flexion was also measured, using either tip of finger to palm distance or total active motion, depending on the available data. These were measured at an average of 1.2 cm and 194°, respectively. CONCLUSIONS: Dorsal spanning plate fixation provides a safe and effective method for treating complex distal radius fractures. In our series, patients had good functional outcomes with few complications.
