By using Materialise OrthoView's automated SmartHip wizzard, planning time for surgeries has reduced by as much as 25%, according to Dr. Andrew Noble, a hip and knee specialist at Palm Beach Orthopaedic Institute in Florida.
Digital pre-operative planning allows the surgeon to easily assess the size of components required, as well as other factors that the duration of the procedure. Having considered a variety of options in advance of the procedure, the surgeon was able to ensure both the equipment and his staff were prepared, thus saving valuable time in the OR.
The patient, an 86 year-old woman who was the primary caregiver for her husband, had previously been an active person in the local community. She was experiencing increasing right knee pain and deformity and was unable to walk without the use of a cane. A physical examination revealed antero-posterior and medial instability with 10-degree hyperextension to 90-degree flexion
OrthoView is able to present the full range of options and compatibilities available with complex modular prostheses on-screen so that the surgeon does not need to memorize them. The surgeon is also able to identify that the correct amount of offset is achievable with the chosen prosthesis.
The patient has a history of hypophosphatemic rickets. The associated bone abnormalities and leg malalignment had been addressed by bilateral closing wedge tibial osteotomies when the patient was approximately 40 years of age. The patient was now experiencing pain in both knees and was having difficulty walking.
A 43 year-old female runner suffered a displaced right femoral neck stress fracture that failed to heal with conservative treatment. She was treated at an outside hospital with percutaneous reduction and internal fixation.
Dr. Mehta is an enthusiastic advocate of digital pre-operative planning and has selected OrthoView software as the solution for his division. Here he explains how his division will benefit from using OrthoView for planning and templating procedures.
This total hip arthroplasty (THA) revision case presented by Mr. Grant Shaw is part of our “Plan to Know” with Orthopaedic Digital Templating Case Study Series, in which orthopaedic surgeons describe cases in which digital pre-operative did or would have enabled better preparation for the OR.
