[Operative treatment in orthopedics and trauma surgery : Are more operations carried out in Germany?]

Abstract

Background: Since 2005, when the Diagnosis-Related Group (DRG) system was introduced, an increasing number of surgical procedures have been reported in Germany. In particular, the numbers of elective arthroplasty and spinal surgery procedures have been controversial.

Objectives: The focus of this study was analyzing the development of spinal surgery, arthroplasty, and fracture management.

Materials and methods: We analyzed the database for all musculoskeletal operating procedure codes (OPS codes 5‑78 to 5‑86) from 2005 to 2013 collected by the German Federal Statistical Office.

Results: With an increase in total patient numbers of 12.8%, there was a rise in in-patient musculoskeletal procedures of 43.5%; the highest increase in procedures was found in spinal surgery (130%). Despite an ageing population, the numbers of hip- and knee arthroplasty procedures initially decreased after 2011 and after 2009 respectively. The number of osteosyntheses showed a slight increase (16%), whereas the number of (elective) implant removals declined (-7%). An increase in novel techniques was noticeable, such as locked plate osteosynthesis (251%), shoulder arthroplasty (402%) or the use of bone substitutes in spinal surgery (+2,011%).

Conclusions: Despite generally increasing volume growth, the numbers of hip and knee arthroplasty cases decreased. In addition to an ageing population and potential economic incentives, technical innovations and new implant systems should be considered when discussing increasing case numbers.
