Dr. Weinschenk earned his medic

al degree at Wake Forest School of Medicine. He completed a residency in orthopaedic surgery at Baylor Scott & White Medical Center – Temple and received advanced training in musculoskeletal oncology through a fellowship at MD Anderson Cancer Center. Following the traditional clinical year, Dr. Weinschenk remained at MD Anderson for an additional year dedicated to clinical and translational research. He joined the UT Southwestern faculty in 2021. He is designated as a Clinical Scholar at UT Southwestern, with substantial efforts dedicated to research in addition to his clinical practice.

New publication alert!

Thanks to some diligent work from some awesome medical students, we are pleased to announce that our systematic review looking at diffusion-weighted MRI for bone and soft tissue tumors is hot off the press! This exciting MRI technology, which essentially boils down to the diffusion of water molecules, can help us distinguish amongst various types of malignancies, differentiate benign from malignant tumors, and also assess response to treatment! Its use is still evolving over time, but is one of the many exciting tools we have in our arsenal to help us beat cancer!

Didn’t take too many photos this year, but in New Orleans was outstanding!

I had the privilege of serving as a mentor in AAOS Launchpad, an educational initiative for senior residents as they prepare for their board exams and transition into fellowship and practice.

Other major highlights this year:
-Awesome lectures and symposiums
-The Terminator was the presidential guest speaker!
-Got to go to the New Orleans Jazz Museum and among other highlights, saved a photo of Sidney Bechet’s sax (for anyone who doesn’t know what a big jazz nerd I am, that was a big deal for me!)
-Awesome time exploring and eating great food with the family!

Had a great time at the Musculoskeletal Tumor Society Annual Meeting in Mexico City! I had the privilege of participating in a hands on workshop exploring innovations in pelvic fixation for oncology patients and was able to showcase some of the research we have done with diffusion-weighted MRI for myeloma patients. This is always a great conference to catch up with colleagues and friends and learn the latest and greatest in musculoskeletal oncology. I also found some time to try some of the amazing food Mexico City has to offer!

First day at OU Health is in the books! I am very excited to begin this new chapter. I am fortunate to already have some exciting challenges on the horizon, both clinically and with research! I also had the privilege of traveling to the Norman campus a few days ago to talk with some folks about some fun collaborations with 3-D printing and biomechanics research. Fortunately, my skeleton, Bob, has also arrived safely! Looking forward to working with the rest of the team and residents here at OU!

For some reason, my 3-year-old wasn’t interested in my speech how scraping out a pumpkin is exactly like curettaging out a benign bone tumor 🤷

This is a patient in his early 20s who had insidious onset of right hip pain. An abnormal lesion was discovered in his right iliac wing. A biopsy confirmed the diagnosis of low-grade osteosarcoma.

Most osteosarcomas required both chemotherapy and surgery, but this being low-grade, only required surgery. After resecting enough bone and soft tissue to achieve a wide margin, specimens are taken to pathology, each surface is inked a different color for later analysis by the pathologist, and the specimen is cut so we can visualize the resected tumor and normal tissue surrounding it. Suture anchors were used to secure a bioprosthetic mesh to the defect in the pelvis and close the abdominal wall to prevent a hernia.

The patient is now ambulating well and has made an excellent recovery!

This is a patient in her mid-60s who unfortunately was diagnosed with metastatic phyllodes tumor, a rare cancer originating in the breast. After spreading to her humerus, she suffered from a pathologic fracture. Sometimes when cancer spreads to bone, we can’t rely on the biology of the bone for the fracture to heal like we can in typical orthopedic trauma. In these cases, sometimes after removing the cancer from the bone, we will fill the defect with bone cement to help reinforce it. When exposing these areas it’s always important to identify and protect critical neurovascular structures, in this case, the radial nerve!

This is an 18-year-old patient with a very large osteosarcoma of the left femur that has grown out of the bone and into much of the soft tissue in the thigh. After initial chemotherapy, the surgery required for this patient was challenging for 2 reasons: (1) getting the tumor out and (2) filling the defect to maintain a functional leg. In this case, I opted for a structural allograft, in which bone from a human donor is used. This bone is size-matched to the patient and is cut to the appropriate dimensions to maintain the patient’s leg length and alignment. It is then fixed to the patient’s own bone with a metal rod as well as plates and screws. This is a great option for someone so young, as it allows them to keep their own hip joint and knee joint!

Giant Cell Tumor...benign, but aggressive!

This was a very interesting case of a patient with a very large giant cell tumor of the tibia around the knee joint. These types of tumors are not cancerous, but they can be locally aggressive, as was seen in this case. It caused significant expansion of the bone and mass effect on important surrounding vessels and nerves.

When caught early, these can be treated with a curettage, where we scrape out the tumor and fill the defect with bone cement or bone graft. In this case, we had to remove the entire top part of the tibia. I chose to reconstruct with an allograft-prosthetic composite, whereby a size-matched allograft tibia was used in combination with a long-stem knee replacement.

I had the honor of traveling to Phoenix, AZ with my hand/upper extremity colleague, Dr. Richard Samade, this weekend to present at the OneAO 2024 conference hosted by .

Dr. Samade and I have a close collaboration exploring the use of 3D printing to help improve care for our patients. He and I co-presented a talk on 3D printing in orthopedic surgery with Dr. Laurent Guiot and Dr. Denis Marcellin-Little, both veterinary orthopedic surgeons who are doing some amazing things with 3D printing in the world of small animal surgery.

It's an exciting time to be an orthopod, whether your patients are humans or animals!
