Background Early techniques of arthrodesis with use of allograft or autogenous graft and
without instrumentation were associated with a high rate of failure. In a classic study, Stauffer …

The definition of successful arthrodesis following anterior lumbar fusion is controversial. The
comparison of different surgical arthrodesis techniques, interbody prostheses, and bone …

Although cervical and lumbar disc replacements are in their spinal surgical infancy with regard
to clinical application, the indications are already delineated. Lumbar disc arthroplasty is …

We studied 100 consecutive patients with potentially unstable fractures and fracture-dislocations
by multiplane computed tomography. The mechanism of failure of the middle …

… Radiographic outcomes are described in detail in Part II of this study by McAfee et al, which
… discussed in more detail in subsequent papers by Holt et al, and McAfee et al, respectively. …

Study Design The biomechanical stability of seven cervical reconstruction methods including
the transpedicular screw fixation was evaluated under four instability patterns. These four …

Study Design. In vitro investigation of cervical adjacent level intradiscal pressures (IDPs)
following a total disc replacement arthroplasty. Objectives. The current in vitro study was …

Study Design. A prospective multicenter study on 100 consecutive surgical procedures.
Objectives. A prospective multicenter study was per formed to evaluate the early perioperative …

There is currently no structured classification system to quantitate heterotopic bone formation
after artificial disk replacement procedures. The purpose of this work was to develop a …

Study Design. An in vitro biomechanical analysis of three anterior instability patterns was
performed using calf lumbosacral spines. Stiffness of the constructs was compared, and …
