Early versus delayed decompression for traumatic cervical spinal cord injury: application of the AOSpine subaxial cervical spinal injury classification system to guide surgical timing
Application of AOSpine subaxial cervical spine injury classification system to explore the optimal surgical decompression timing for different types of traumatic cervical spinal cord injury (CSCI).
Methods
A single-center prospective cohort study was conducted that included patients with traumatic CSCIs (C3–C7) between February 2015 and October 2016. After enrollment, patients underwent either early (< 72 h after injury) or late (≥ 72 h after injury) decompressive surgery of the cervical spinal cord. Each group was divided into A0, A1-4, B, C/F4 and F1-3 subgroups. The primary outcomes were ordinal changes in the ASIA Impairment Scale (AIS) and the Spinal Cord Independence Measure III (SCIM version 3) at a 12-month follow-up. The secondary outcomes included length of hospital stay, postoperative neurological deterioration, other complications and mortality.
Results
A total of 402 patients were included. Of these, 187 patients underwent early decompression surgery, and 215 patients underwent delayed decompression surgery. Statistical results included the following comparisons of the early vs late groups: AIS improvement ≥ 1 grade (combined groups: P < 0.0001; A0: P = 0.554; A1-4: P = 0.084; B: P = 0.013; C/F4: P = 0.040; F1-3: P = 0.742); AIS improvement ≥ 2 grades, P = 0.003 for all groups; SCIM version 3 (combined groups: P < 0.0001; A0: P = 0.126; A1-4: P = 0.912; B: P = 0.006; C/F4: P = 0.111; F1-3: P = 0.875).
Conclusion
Type A and F1-3 fractures are not required to undergo aggressive early decompression. Type B and type C/F4 fractures should receive early surgical treatment for better clinical outcomes.

Mit dem demographischen Wandel versorgt auch die Chirurgie immer mehr betagte Menschen. Von Entwicklungen wie Fast-Track können auch ältere Menschen profitieren und bei proximaler Humerusfraktur können selbst manche 100-Jährige noch sicher operiert werden.
Patienten, die von Ärztinnen behandelt werden, dürfen offenbar auf bessere Therapieergebnisse hoffen als Patienten von Ärzten. Besonders gilt das offenbar für weibliche Kranke, wie eine Studie zeigt.
Ob bei einer Notfalloperation nach Schenkelhalsfraktur eine Hemiarthroplastik oder eine totale Endoprothese (TEP) eingebaut wird, sollte nicht allein vom Alter der Patientinnen und Patienten abhängen. Auch über 90-Jährige können von der TEP profitieren.
