Working Groups
Adult spinal deformity is a multifaceted area of research. To ensure that all aspects of the field are given thorough consideration, the ISSG has divided into various working groups. Members participate in the groups that interest them most and are organized by a fellow ISSG member who has demonstrated excellence and expertise in that specific sphere.
Complications/ Revisions
Leader: Eric Klineberg
Areas of Interest: predicting intra- and peri-operative complications; effect of multiple complications on HRQOL; increased complications associated with larger global sagittal correction; clustered complications; effect of dural tears on outcomes and other complications; frailty scores associated with value metrics; neurologic complications in ASD surgery; surgical invasiveness; rhBMP-2 and complications
Proximal Junctional Kyphosis/ Failure (PJK/ PJF)
Leader: Han Jo Kim
Areas of Interest: predicting PJK, radiographic thresholds for PJK, compensatory changes due to PJK, revision for PJK
International Collaboration/ Ethnicity
Leaders: Christopher Ames, Virginie Lafage
Areas of Interest: ethnic variations in spinal deformity, health related quality of life, and satisfaction; role of ethnicity in alignment compensation
Complex Realignment
Leader: Munish Gupta and Alan Daniels
Areas of Interest: predicting alignment based on construct length, termination level and procedure type; coronal malalignment associated with poor patient-reported outcomes; acetabular anteversion changes; reducing rod breakage and nonunion in PSO; pevlic tilt after spinopelvic realignment; drivers of disability (disability to deformity burden ratio); intraoperative assessment of alignment
Econ and Outcomes
Leader: Richard Hostin and Michael Kelly
Areas of Interest: cell saver as a cost minimizer; costs and causes of readmission; hospital direct costs vs. medicare allowables; effect of timing of readmission on cost. recovery kinetics; outcomes of operative versus nonoperative treatment; impact of pain, self-appearance, and depression on outcomes; treatment satisfaction
Cervical
Leader: Christopher Ames and Justin Smith
Areas of Interest: cervical alignment changes after lumbar PSO; new onset cervical deformity in non-operative treatment of ASD; novel cervical angular measures; complication rates associated with cervical deformity; post-operative dysphagia; long-cassette standing x-rays for cervical pathology; varied approches in cervical deformity treatment
Minimally Invasive Surgery (MIS)
Leaders: Praveen Mummaneni
Areas of Interest: minimally invasive versus open surgery, complications in MIS, construct length in MIS, stand-alone multi-level lateral lumbar interbody fusion, best versus worst outcomes in MIS, impact of obesity in MIS versus open surgery
