S.A.M.W.I.S.E. G.A.M.G.E.E. - An Orthopedic Washer Retrieval System
S.A.M.W.I.S.E. G.A.M.G.E.E. - An Orthopedic Washer Retrieval System
In coordination with the project sponsor, Roman Natoli, MD, PhD, the S.A.M.W.I.S.E. G.A.M.G.E.E. system was developed to assist in sacroiliac (SI) joint fixation hardware removal. SI joint fixation hardware is a screw and washer system that aids in healing posterior pelvic ring factures and is often a permanent solution for patients facing injury. However, when removal of this hardware is deemed necessary by an orthopedic doctor, many surgeons are faced with a washer that resists explanation. The S.A.M.W.I.S.E. G.A.M.G.E.E. surgical system keeps patients and surgeons in mind to address this pain point.
Background
Background
Posterior pelvic ring injuries occur in high energy impacts and are common in the cohorts of 15-30 & 50-70 years of age. 10% of these fractures require implantation of fixation hardware to stabilize and heal the patient. Percutaneous placement of a screw and a washer across the SI joint is the most common method for posterior pelvic ring stabilization. It is quick, easy, and non-invasive.
There is a 6 month recovery process associated with SI joint fracture fixation surgery. Studies show that 5-18% of SI patients require revision surgery inside or outside of this time frame due to:
Low incidence of infection
Persistent pain experienced by the patient
Implant failure, or
Patient request for complete metal removal before end-of-life.
It is not uncommon that extraction of the SI hardware fails in removing the washer from the patient’s gluteal anatomy. This poses no harm to the patient but can present a burden to the surgeon who tries to retrieve it and extra invasiveness to those that demand it out. The exact cause for washer retention is not well understood however possible indentation into the soft periosteum of the ilium, anatomical constraints such as gluteal musculature, and reactive tissue that grows around the implant have all been identified as possible reasons for retention. Often, the patient will stay in this state, however the desired outcome for patients and surgeons alike is complete hardware removal.
5 Ideals Guided our Design
The system is to be minimally invasive to optimize patient healing times
The system shall be equipment compatible with existing technology in the the operating room
Operating room standards, sterility and biocompatibility, are a must
Orthopedic tools must be tough and durable, and must not break during use
The system must successfully access, collect, and remove the washer from the patients anatomy
