A comparison of different methods used to diagnose pseudarthrosis following posterior spinal fusion for scoliosis.

Allogenic versus autologous cancellous bone in lumbar segmental spondylodesis: a randomized prospective study

“…In this study, rather restrictive parameters were chosen for the evaluation of fusion. Nevertheless, it must be taken into account, that the evaluation of radiological procedures is subject to a predictive value of no more than 70% [7,10]. Surprisingly, we were able to observe bone bridging around the cage in most of the cases despite not placing graft at this position (see Fig.…”

Translation and Cross-cultural Adaptation of the Lower Extremity Functional Scale Into a Brazilian Portuguese Version and Validation on Patients With Knee Injuries

“…9 Accurate assessment of function has been shown to be of value for rehabilitation to help provide treatment based primarily on individual disabilities and not solely on clinical status generated from diagnostic exams. 12 Assessing patients' perception about their quality of life and improvements in clinical and functional status is becoming more routine in the scientific and clinical communities.…”

A new semirigid implant for instrumentation of scoliosis: preliminary report

“…A The DDS system, B the Luque-type instrumentations, and C Siemsen's proposed posterior cable device. Direction of distractive and transversal forces represented by black arrows, compressive forces by open arrows able methods for detecting pseudarthrosis, such as CT scans or anteroposterior tomography [8], were not utilized for ethical reasons in this set of young pain-free patients.…”
