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.
-
Practice Audit
Leader: Virginie Lafage
Areas of Interest: site variability in technique and outcomes; evolution of surgical approach, complications and outcomes; performance analysis of three-column osteotomies; comparing 2 vs. 1 attending surgeon; quantifying patient-reported individualized goals
-
Cervical
Leader: Christopher Ames
Members: D Kojo Hamilton, Eric Klineberg, Frank Schwab, Gregory Mundis, Han Jo Kim, Justin Scheer, Justin Smith, Kai Ming Fu, Peter Passias, Praveen Mummaneni, Robert Eastlack, Themistocles Protopsaltis, Vedat Deviren
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
-
Complex Realignment
Leader: Dr. Munish Gupta
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
-
Complications/ Revisions
Leader: Eric Klineberg
Members: Alan Daniels, Alexandra Soroceanu, Christopher Ames, Douglas Burton, D. Kojo Hamilton, Gregory Mundis, Han Jo Kim, Robert Hart, Eric Klineberg, Themistocles Protopsaltis, Justin Scheer, Justin Smith, Michael Kelly, Munish Gupta, Peter Passias, Shay Bess, Virginie Lafage
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
-
Health Economics
Leader: Richard Hostin
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
-
Proximal Junctional Kyphosis/ Failure (PJK/ PJF)
Leader: Dr. Han Jo Kim
Areas of Interest: predicting PJK, radiographic thresholds for PJK, compensatory changes due to PJK, revision for PJK
-
Outcomes, Health Related Quality of Life (HRQOL)
Leader: Richard Hostin
Areas of Interest: recovery kinetics; outcomes of operative versus nonoperative treatment; impact of pain, self-appearance, and depression on outcomes; treatment satisfaction
-
Minimally Invasive Surgery (MIS)
Leaders: Praveen Mummaneni
Members: Behrooz Akbarnia, Neel Anand, Dean Chou, Vedat Deviren, Robert Eastlack, Richard Fessler, Adam Kanter, Praveen Mummaneni, Gregory Mundis, Pierce Nunley, David Okonkwo, Paul Park, Christopher Shaffrey, Khoi Than, Juan Uribe, Michael Wang
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
-
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
-
Pediatric Collaboration
Leaders: Michael Kelly, Han Jo Kim
