Weight Bearing CT Advances Planning for Forefoot Reconstructive Surgery

Think of a surgical procedure like a construction project. No contractor would build a building without a full set of plans, cross-sectional diagrams and 3D renderings. Dr. Bob Baravarian, DPM, feels foot surgeons should be just as prepared.

As he explained in Podiatry Today, Dr. Baravarian has always been interested in architecture and real estate, yet was drawn to 159682158975132.Zfw2RIZiU5Lh04gznDby_height640medicine.

Dr. Baravarian sometimes works next to a hip & knee surgeon in the OR. One day, he observed the hip & knee surgeon had a digital tool that laid out an exact surgical plan for the osteotomy he was performing. The plan rendered leg length and acetabular rotation a non-issue.

Soon after, Dr. Baravarian incorporated a pedCAT weight bearing CT imaging system into his podiatric practice. He found he could plan angular corrections to the degree, calculate the exact size of a graft for an Evans procedure, and could even plan the amount of rotation necessary for anatomic alignment of the hindfoot.

 

Overtime, he began to apply the same methods to forefoot procedures as well.

  • For hallux valgus cases, he scans the patient in the post-corrected position so he can determine if a hindfoot alignment correction is also needed.
  • For hallux rigidus cases, he uses weight bearing CT to evaluate the level of articular damage and the possibility of cartilage graft procedures. “This is impossible to do at such high levels with plain radiographs,” Dr. Baravarian said in the Podiatry Today article.

pt07treatment1 (1)Bilateral, weight bearing three dimensional views of the foot and ankle give specialists the data they need to create optimal treatment plans. The pedCAT, with a scan time of one minute, is a compact, ultra-low dose CT imaging system that is ideal for orthopedic and podiatric clinics. Patients benefit from the convenience of point-of-care advanced diagnostic imaging, and the pedCAT automatically generates all standard X-Ray views in addition to the full CT volume.

As software programs become more advanced, Dr. Baravarian said, surgeons may be able to perform osteotomies and shift the bones in preoperative planning, which will allow even more advanced planning along with far less operative time and less risk to the pt07treatment3 (1)patient.

Dr. Baravarian is the Chief of Podiatric Foot and Ankle Surgery at the Santa Monica UCLA Medical Center and Orthopedic Hospital, and Director of the University Foot and Ankle Institute in Los Angeles.

Exclusive Video From The First pedCAT Weight Bearing CT Scientific Users’ Meeting in Berlin

meeting-83519_960_720 (1)The first pedCAT Weight Bearing CT Scientific User’s Meeting recently convened at the 2016 Foot International (EFAS, DAF, I-FAB) in Berlin. The meeting focused on weight bearing cone beam CT (WBCT) technology and the potential applications and challenges it presents.

Fill out this form to access the video.

Look for several interesting items as you watch:

  • Professor Martinus Richter’s work included a time workflow study on the use of X-Ray,  conventional medical CT, and the pedCAT; the results will surprise you. His study also showed how weight-bearing  CT measurements are more accurate than X-Ray measurements.
  • Dr. Arne Burssens’ study on hindfoot alignment answered critical questions: How do we identify varus and valgus, how do we accurately measure them, and how can we be sure that the measurements are clinically useful and reproducible?
  • Dr. Francois Lintz gives us a sneak peek at a new weight-bearing measurement CT tool that will be available exclusively in CubeVue, pedCAT’s software. It will enable users to measure alignment in three dimensions, and distinguish between normal and pathological cases.
  • Dr. Cesar Netto’s study focused on adult acquired flatfoot deformity, comparing  measurements on weight bearing CT vs non-weight bearing CT.
  • Dr. Michael Wachowsky’s study focused on the use of weight bearing CT  with pediatric patients, and asks: With the new weight bearing CT technology, what will be the exact definitions of the measurements?

The challenge created by this new technology is clear: How do we now define what we are measuring, since the current X-Ray methods have just been rendered obsolete?

“We can’t have non-weight bearing CTs and say anything about alignment – that’s over,” concluded Dr. Charles Saltzman. “What do we want to measure, and how do we know what we’re measuring represents reality?”

What Is Cone Beam CT? The Science Behind the Image. Part 1: Overview

Within the last two decades, Cone beam Computed Tomography (CBCT) imaging applications have diversified in both the medical and industrial applications.  Developments in medical diagnostic applications were pioneered in the Dental industry in 1996, when the first commercially produced Dental/Maxillofacial CBCT scanner was introduced.

A number of factors contributed to the commercialization of cone beam CT. First was the introduction of more cost efficient flat panel detectors that were capable of achieving higher resolution. The first dental CBCT systems had image intensifiers coupled with CCD cameras to capture the data used for creating images. These systems were prone to distortions and required frequent calibration. Compared to the image intensifier systems, the new FPDs were less bulky, which in turn allowed the scanners themselves to be designed and manufactured to take up less room. Because the detectors were significantly more sensitive to x-ray photons, the x-ray sources could be made smaller as well.

Faster computer processors using multiple cores, greater working memory capacity, and larger capacity storage drives – all at cheaper prices – made CBCT technology more affordable.

Once CBCT technology was available to the dental specialties, the 3D data was used to create planning and placement tools for dental implants. CBCT technology also revolutionized orthodontics, airway and sinus evaluation, and maxillofacial surgery and reconstruction planning and evaluation.

CBCT applications continue to grow because of the technology’s affordability, equipment design and ease of use.

In the next parts of this series on CBCT technology, we will look into the different components of a CBCT system in more detail.

Need Bunion Surgery? A Weight Bearing CT Scan Could Help You Decide

When a patient appears to have a bunion, a physician typically orders traditional foot X-Rays as part of the clinical evaluation. The X-Rays capture three views of the foot- dorsoplantar, medial oblique, and lateral. But is this enough information to understand complex, three-dimensional object such as the foot? 

A growing number of foot & ankle specialists are advocating that there may be better way to evaluate this common deformity.

“Weight bearing computed tomography scans are beginning to take our understanding to the next level,” Dr. Paul Dayton, DPM, of Des Moines, IA, said in a roundtable discussion on bunions published in the Foot & Ankle Specialist academic journal. “Once you see the connection between coronal rotation and what we have traditionally evaluated on AP radiographs, it opens up a whole new understanding.”

On X-Rays, physicians have to “mentally interpolate” the valgus component of the bunion because they do not adequately capture the frontal plane, said Dr. Robert Weinstein, DPM, FACFAS, of Atlanta, explained in a CurveBeam case study.  

“Since the condition is a tri-plane deformity, we need to understand all of the components and their angular values contributing to the deformity,” Weinstein said. “Better deformity analysis leads to better pre-operative planning, surgical execution, and post-operative results.”

The new data on the coronal position is “exciting” because it explains so many of foot and ankle specialists’ previous questions, Dayton said.  

Weight bearing CT imaging also allows for evaluating deformities that involve external rotation. Rotation of one or more metatarsals, including displacement of the sesamoids, cannot be clearly seen in standard foot X-ray imaging. The lack of the weight-bearing aspect in traditional medical CT imaging means the physician cannot evaluate displacement and rotation under load.

Hallux Valgus Blog Post Image 1
One component of the deformity that is seldom quantified is external rotation, or frontal plane deviation. The presence of rotation of the hallux implies a more complex deformity. A very careful assessment of the first metatarsophalangeal joint architecture, including sesamoid position, their condition, and erosion or flattening of the crista on the inferior first metatarsal head is essential.

It has long been known that in hallux valgus or bunions the relationship between the metatarsal head and the sesamoids is altered,” Andy Goldberg, MD, MBBS, FRCS (TR and Orth), of Stanmore, United Kingdom, told Lower Extremity Review magazine. he said. “The sesamoid bones should sit underneath the metatarsal head, while in hallux valgus the big toe drifts off the sesamoids and the tip of the big toe points outwards. But our research has shown that in many cases the cartilage is worn, which in essence is localized arthritis, and we believe that this could affect the outcome of surgery.”

CubeVue, the pedCAT weight bearing CT imaging system’s custom visualization software, allows physicians to create oblique and frontal-plane images of varying angles and thicknesses from the weight bearing CT data.

Weight bearing CT images could have an impact on the technique a physician selects to repair a bunion, Dr. Dayton said.

“The knowledge that the sesamoids can be in normal position medial and lateral to the crista yet look dislocated on the AP X-ray because of pronation completely changes our mindset about the need for capsular balancing,” Dayton said. “We can see that in those cases supination corrects the deformity.”

Standing CT vs. MRI for Advanced Visualization of Knee Cartilage and Meniscus

At the 2016 OARSI World Congress in Amsterdam, Netherlands, Dr. Neil Segal, MD, MS, and Dr. Ali Guermazi, MD, PhD , presented a poster describing “Advances In Visualization Of Knee Cartilage And Meniscus With Standing Computed Tomography Arthrography”.

Standing CT arthrography (SCTa) has also been shown to have some distinct advantages over MRI, according to the poster presentation. “Potential advantages of SCTa over non-weight-bearing MRI/MRA include: 3D measures of meniscal position and morphology; detection of pathology not detected in unloaded positions; and ability to bear weight bilaterally in a functional position, better recreating the magnitude of muscle and external forces acting about the knee during usual standing….  SCTa can be obtained in multiple knee flexion angles, while an MRI knee coil may permit imaging only with the knee in extension, and SCTa is less expensive than MRI.”

Visualization of the boundaries of the menisci was achieved to a similar degree on SCTa and MRA.

As part of the background for their presentation, Drs. Segal and Guermazi stated that “MRI is the standard for non-invasive visualization of cartilage and menisci, and … Absence of weight bearing limits evaluation of the functional position and configuration of these structures…Advances in standing CT (SCT) have allowed 3D imaging of the knees while under physiological loads, similar to fixed-flexed or semi-flexed radiograph protocols.”

Their objective was to evaluate a protocol for SCTa for imaging weight bearing cartilage and menisci and to assess potential advantages over non-weight bearing MRI.

Although the sample size was small, the results were noteworthy. As shown in the images, SCTa permits evaluation of cartilage and menisci in three dimensions, while the patient is standing and under physiological load. Furthermore, SCTa, “may be useful for assessment of menisci as well as tibiofemoral and patellofemoral cartilage in functional stance,” according to the presentation.

The two participants in the study were a 42-year-old man without osteoarthritis (Figures 1 and 2), and a 67-year-old woman with KL2 knee osteoarthritis (figures 3-5). The participants had a similar contrast agent applied.

The actual imaging techniques used were fixed-flexed (approximately 20°) SCTa (INVESTIGATIONAL ONLY cone beam CT knee imaging system*, CurveBeam, Warrington, PA, USA) and non-weight bearing MRI (Siemens TrioTim, Washington DC, USA).

“Following 2-3 minutes of unloaded knee flexion and extension, a low-dose SCT scan was acquired utilizing cone beam reconstruction. Participants were positioned with the tips of the great toes, patellae, and the anterior superior iliac spines coplanar to each other and the feet 10°externally rotated. Scans were acquired with a 0.3mm isotropic voxel size (20x 35x35cm) with an effective radiation dose of approximately 0.1 mSv. 10 minutes following SCTa, MR arthrography was acquired (NEX=1, ETL=3, Slice thickness=2 mm, Slice spacing 2 mm, Matrix= 240 x 320, FOV=140 mm with axial T1 fat-sat (TR=712 msec, TE=12 msec); coronal T1 fat sat (TR=730 msec, TE=10 msec); and sagittal T1 fat sat (TR=796 msec, TE=10 msec).

pedCAT: Early Diagnosis of Osteomyelitis in the Diabetic Patient

The pedCAT weight bearing CT imaging system could identify bone infection at an early stage, and possibly prevent amputations, researchers at the California School of Podiatric Medicine at Samuel Merritt University determined in a report.

The researchers outlined two cases where “the use of CBCT device enabled us to diagnose and treat osteomyelitis in a timely manner, preventing its spread to adjacent bone and soft tissue, and minimizing the amount of required surgical resection.”

Plain radiograph is the primary imaging modality for the osteomyelitis diagnosis, the report states, but X-Rays may not reveal osteolytic changes for up to 20 days from the onset of infection or until the bone density is reduced by 30 – 50 percent.

Osteomyelitis is one of the most feared complications of diabetic foot ulceration, which often leads to lower extremity amputation and disability. Early diagnosis of osteomyelitis increases the likelihood of successful treatment and preserving ambulatory function. Unfortunately, most of the currently available imaging modalities are of limited use in assessing early stages of bone infection due to their low specificity and sensitivity for early osteolytic changes.

Magnetic resonance imaging (MRI) is more sensitive and specific than X-Ray, and yields greater accuracy in detecting soft tissue abscesses or early osteomyelitis in patients with high clinical suspicion and negative radiographs. In controversial or uncertain cases where MRI is not available, other imaging techniques such as indium-labeled leukocyte imaging combined with radionucleotide bone scan can be used as an alternative. (“Preventive and Therapeutic Strategies for Diabetic Foot Ulcers” – Foot & Ankle International® 2016, Vol. 37(3) 334– 343 – Chris C. Cychosz, BS, Phinit Phisitkul, MD, Daniel A. Belatti, BS, and Dane K. Wukich, MD).

Nuclear Imaging and MRI perform well in detecting early onset of osteomyelitis; but they are expensive to own and operate, are time-consuming in their acquisition of images.

What is desirable for early detection is a method that is accurate, inexpensive, and readily available. Cone beam CT, and the pedCAT in particular, fills this gap nicely.  The device is small enough to fit into most practices, offers high-resolution 3D imaging capabilities, and has a reduced radiation dose compared to traditional CT, according to the report.

Lead author Alexander M. Reyzelman, DPM,  and his associates reported on two diabetic patients who presented with infected neuropathic foot ulcers and were evaluated for potential osteomyelitis using plain film radiographs and the pedCAT CBCT scanner. In both cases, the “pedCAT was instrumental in identifying bone infection. The diagnosis of osteomyelitis was later confirmed by positive findings on bone biopsy. The use of CBCT device enabled us to diagnose and treat osteomyelitis in a timely manner, preventing its spread to adjacent bone and soft tissue, and minimizing the amount of required surgical resection.”

Case 1

A 49 year old diabetic female presented with an infected neuropathic ulcer at the lateral aspect of her fourth digit. The ulcer demonstrated malodor, cellulitis that extended to fourth metatarsophalangeal joint and positive probe-to-bone test. The plain film radiographs and CBCT were utilized in order to rule out osteomyelitis and assess the extent of soft tissue infection. The weight-bearing X-rays of the affected foot revealed subtle lucency at the lateral aspect of the proximal phalanx of the fourth digit, which was contiguous with the ulcer location. However, this finding alone was not sufficient to yield a conclusive diagnosis.  The images obtained using PedCAT clearly demonstrated the break in the cortex and the area of osteolysis involving the proximal phalanx of the fourth digit. The head of the fourth metatarsal and adjacent digits appeared intact. These findings, in conjunction with the clinical appearance of the affected digit, led to a preliminary diagnosis of osteomyelitis. The patient was treated with an arthroplasty of the fourth proximal interphalangeal joint, and has fully recovered. The bone specimens obtained intraoperatively were sent for biopsy, which confirmed our preliminary diagnosis of osteomyelitis.

Case 2

A 53 year old diabetic male presented with an infected neuropathic ulcer at his fifth metatarsal head, which exhibited malodor, edema and erythema extending through tthe plantar lateral aspect of  fifth metatarsal shaft and probed to joint capsule. The X-rays demonstrated no signs of bone involvement, while CBCT revealed distinct areas of cortical lysis and bony fragmentation of the fifth metatarsal head. The proximal two thirds of the shaft of the fifth metatarsal appeared unaffected, with intact cortex, uniform bony density and lack of osseous fragmentation. The patient was treated with partial resection of the fifth metatarsal. The bone biopsy has confirmed our preliminary diagnosis of osteomyelitis.

In the concluding discussion, Dr Reyzelman noted: “Though in our case studies we have not taken advantage of the option allowing to scan the patient in both, a weight-bearing and a non-weight bearing positions, this option could be highly useful for evaluation of complex fractures and dislocations of the foot and ankle.”

Orientation of the Subtalar Joint: Measurement and Reliability Using Weight Bearing CT Scans

Is there a reliable method to predict the type and perhaps the extent of osteoarthritis one might find in the ankle? Based on a recent article, which the examined the varus and valgus orientation of the talus and the configuration of the subtalar joint under weight bearing conditions, the possibility is there.

“A majority of the patients with ankle osteoarthritis present with an asymmetric wear pattern (eg, varus or valgus type),” according to a study published in 2009 by Valderrabano V, Horisberger M, Russell I, Dougall H, Hintermann B. titled, “Etiology of ankle osteoarthritis.”

Evaluation of these wear patterns, however, remained a challenge until recently, when Nicola Krähenbühl, MD, Michael Tschuck, Lilianna Bolliger, MSc, Beat Hintermann, MD, and Markus Knupp, MD published “Orientation of the Subtalar Joint: Measurement and Reliability Using Weightbearing CT Scans.” (Foot & Ankle International® 2016, Vol. 37(1) 109–114.)

Osteoarthritis of the ankle joint is relatively common and found in 1 percent of the world’s population, and a majority of those patients present with an asymmetric wear pattern (eg, varus or valgus type), according to the authors. Furthermore, up to 60 percent of the patients suffering from an osteoarthritic ankle joint develop talar tilt with progression of the osteoarthritic process.

Current research suggests this condition is caused by deformities of the lower leg and knee joint, ligamentous laxity, tendon dysfunction and neurologic disorders. Recently, it has been proposed that the adjacent joints and, particularly, the subtalar joint may have a major influence on this process.  “However, it is rather difficult to evaluate the orientation

of the subtalar joint using conventional radiographs; CT scans would be more appropriate,” the authors posit.

To distinguish between varus/valgus configuration of the subtalar joint, Van Bergeyk et al introduced the subtalar vertical angle (SVA) in 2002 using non weight bearing CT scans. “Today, weight bearing CT scans can be performed, leading to a better understanding of the functional anatomy of the hindfoot,” the article states.

Weight bearing CT technology became available in 2012. Weight bearing imaging only had been available in 2-dimensional X-Ray imaging prior to this, but weight bearing combined with computed tomography was needed to properly measure the SVA without superimposition of non-relevant anatomy that might throw off the measurement, including analyzing the shape of the subtalar joint. The subtalar joint is especially difficult to clinically and radiographically assess in 2D, due to the superimpositions, and attempts to artificially stress the joint and then scan using a conventional (non weight bearing) CT produced inconsistent results.

“Using weight bearing CT scans, we assessed the reproducibility of the SVA and analyzed the orientation of the subtalar joint in patients with asymmetric ankle osteoarthritis. We hypothesized that the SVA would provide reliable and reproducible measurements in varus ankles presenting with a varus subtalar joint and valgus ankles with a valgus orientation of the subtalar joint, respectively,” the authors said.

Using the new technology to view the joints, including utilization of the SVA measurement, the authors concluded the SVA measurements were reliable and consistent. “In our cohort, varus osteoarthritis of the ankle joint occurred with varus orientation of the subtalar joint whereas in patients with valgus osteoarthritis, valgus orientation of the subtalar joint was found,” the study said.

The authors found the results for the healthy cohort were significantly different, suggesting the orientation of the subtalar joint may play an important role in the development of ankle joint osteoarthritis.

Weight bearing CT not only allowed the authors to clinically and radiographically assess the ankle joints under the patient’s normal weight bearing conditions, but it also enabled them to make consistent and reproducible measurements.

His decade old X-Ray system was failing, and feeling like a warrior without his weapon, Dr. Michael Chin, DPM, knew it needed to be replaced fast.

“We could have gotten a DR system, but at the end of the day, I wanted something that was unique, and something that would change the way I practice,” Dr. Chin said.

Dr. Chin participated in a panel discussion about new technology at the Foot and Ankle Business Innovations meeting in Chicago on Jan. 30. Dr. Chin practices at The Running Institute in downtown Chicago.

Dr. Michael Chin, DPM, at FABI

Dr. Chin uses the pedCAT for all of his X-Ray and CT imaging. His X-Ray revenues cover the device’s monthly capital lease payment, and the approximately 20 CTs he and his associate order every month provide his practice with an additional revenue stream.

Dr. Chin said he is able to order a CT scan and his staff can get payer authorization in the same day. This saves his patients from having to come in for a follow-up visit.

“We can fill that slot that we would have used for a follow up with another patient,” Dr. Chin said.
