To review/report 5-year follow-up data on patients diagnosed with thoracic and thoracolumbar kyphosis (TK/TLK) treated with posterior-only spinal fusion.
Summary of background data
TK/TLK was initially treated with combined anterior/posterior spinal fusion, evolving into widespread treatment with posterior-only spinal fusion.
Methods
Forty-three patients who underwent a posterior-only spinal fusion for a primary diagnosis of TK/TLK from 1999 to 2009 with > 5-year follow-up were identified. Preoperative/postoperative/final follow-up measurements were recorded from full-length standing radiographs. Prospectively collected outcome scores were reviewed for the same time points, and charts were examined for complications.
Results
Patient age averaged 33 years (range 13–77), and follow-up averaged 5.6 years (range 5–12.2). Diagnoses included Scheuermann’s disease (N = 15, 35%), idiopathic (N = 10, 23%), pseudarthrosis (N = 6, 14%), iatrogenic (N = 4, 9%), degenerative (N = 3, 7%), post-traumatic (N = 3, 7%), and congenital kyphosis (N = 2, 5%). Average correction of 44.3° (46%; 92.8° preoperatively vs 48.5° postoperatively) was achieved through posterior-only surgery. Loss of correction averaged only 1° in the instrumented segments at final follow-up. Eleven patients had a complication; proximal junctional kyphosis was the most common (N = 3, 7%). One patient lost intraoperative monitoring and one had temporary neurological deterioration postoperatively, but there was no permanent deficit. No pseudarthroses occurred. ODI scores improved 17.2 points on average (p = 0.01). SRS scores improved in all domains (average 0.79, p < 0.001).
Conclusion
Pedicle screw constructs permit effective posterior-only correction of TK/TLK that is maintained at the 5-year follow-up time point. Patients report improvement, via outcome questionnaires, at the same follow-up time points.

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.
