Expert care at the intersection of cancer, function, and innovation.
Dr. Geiger’s expertise spans the following categories
Malignant Bone Tumors
Primary bone cancers like osteosarcoma, Ewing sarcoma, and chondrosarcoma are rare but serious. They originate in the bone and often require a combination of surgery, chemotherapy, and sometimes radiation. Treatment goals include removing the tumor, preserving as much healthy tissue as possible, and helping patients maintain mobility and quality of life. Treatment plans are coordinated with our multi-disciplinary Sarcoma Tumor Board.
Soft Tissue Sarcomas
These are cancers that arise in muscles, fat, nerves, and other connective tissues. They can be large or small in size and are often painless. Early diagnosis and a multidisciplinary approach are key to successful treatment, which typically includes surgery and radiation with or without chemotherapy.
Benign Bone Tumors
Not all bone tumors are cancerous. Many are benign, meaning they don’t spread to other parts of the body, but they can still cause pain, weaken bone, or interfere with movement. Common examples include osteochondromas, enchondromas, and non-ossifying fibromas. Treatment often involves monitoring, but in some cases, surgery is needed to prevent fractures or remove the growth entirely.
Pediatric Sarcoma
Bone and soft tissue sarcomas make up 10–15% of childhood cancers, with ~1,500 U.S. cases annually. Treatment often requires advanced imaging, systemic chemotherapy, and complex limb salvage surgeries by a multidisciplinary team.
Because these young patients face long-term survivorship, the durability of oncologic reconstructions is a key focus for Dr. Geiger. One of only two orthopaedic oncologists fellowship-trained in bone transport, he uses distraction osteogenesis to preserve native joints and regrow bone—providing the most durable, functionally restorative surgeries available for pediatric sarcomas.
Metastatic Bone Disease
Bones are a common site to which many cancers can spread —particularly from the breast, lung, prostate, kidney, and thyroid. These metastatic lesions can cause severe pain, fractures, and loss of function. Orthopedic oncology plays a vital role in stabilizing affected bones and improving a patient’s ability to move and live with less pain.
