UCLA Health excellence in orthopaedic oncology

Our orthopaedic oncology doctors perform the highest volume of surgery for bone and soft tissue tumors on the West Coast. We also rank among the top three highest-volume treatment centers in the country. This means that children and adults receive expert treatment from physicians with vast experience. Our team offers comprehensive, state-of-the-art care with compassion.

Highlights of our program include:

Team-based approach: Experts from radiation oncology, medical oncology, orthopaedic oncology and surgical oncology regularly meet to discuss each patient’s unique needs and find an effective treatment plan. This cohesive tumor board includes physicians who have been working together for many years. Patients benefit from their collective experience and knowledge of leading-edge treatment options.

Coordinated, patient-centered care: Orthopaedic oncologists work closely with musculoskeletal radiologists to coordinate clinical and diagnostic care so patients can get answers quickly. Our aim is to ease patients’ anxieties during a stressful time. Patients also have access to a wide range of subspecialists throughout the UCLA Health system, and we can easily coordinate any necessary referrals.

Limb-sparing emphasis: All our orthopaedic oncologic surgeons are trained in limb salvage. When it is safe to do so, we perform surgeries that preserve the limbs, maintaining function and quality of life for patients.

Physician expertise: Our surgeons have specialized training in microsurgery and endoprosthetic reconstruction (limb salvage surgery with implants). We also work closely with other surgical subspecialties to offer comprehensive surgical care for all patients.

Advanced treatment options: Our institutional history boasts the largest series of metal implants for limb salvage procedures in the region. UCLA Health specialists use a wide range of advanced techniques, including custom implants for particularly complex needs, targeted muscle reinnervation for phantom limb pain and expandable implants for limb-length equality.

Our areas of care

The orthopaedic oncology team collaborates with multiple specialists throughout UCLA Health to offer targeted, comprehensive care. Areas of care include:

Sarcoma Program

Our orthopaedic oncologists care for patients with soft tissue tumors through our specialized Sarcoma Program. We are one of the nation’s busiest sarcoma programs, treating more than 1,200 patients each year. Patients can find leading-edge care close to home at several clinic locations throughout the greater Los Angeles region.

Conditions orthopaedic oncologists treat

We treat the full range of cancerous (malignant) and noncancerous (benign) bone and soft tissue tumors, including:

Benign soft tissue tumors

These noncancerous tumors grow in the soft tissues, which include muscles, fat, blood vessels, tendons and nerves. Tumor types may include:

Ganglion cyst: Round or oval jelly-filled lumps beneath the skin, usually occurring at the wrist

Giant cell tumor of soft tissue: Tumors that are made up of many unusually large or “giant” cells formed from the joining of several smaller cells

Glomus tumor: A growth starting in the glomus body, a component of the inner layer of skin (dermis)

Lipoma: A fatty lump that develops between the muscle and skin 

Neurofibroma: A tumor that grows on nerves, forming a soft bump on or beneath the skin

Schwannoma: A tumor that starts in Schwann cells, which protect and support nerve cells

Tenosynovial giant cell tumor of the tendon sheath: Giant cell tumors that form in the tissue that surrounds tendons (tendon sheath), often occurring in the hands or feet

Malignant soft tissue tumors

Also known as soft tissue sarcomas, these cancerous tumors start in any of the soft tissues. Types include:

Epithelioid sarcoma: A rare, slow-growing tumor usually starting in the soft tissue of the arms or hands

Invasive skin cancer: Skin cancer that has grown past the outer layer of skin (epidermis) and into the dermis and surrounding tissues

Leiomyosarcoma: A rare cancer that grows in smooth muscles, which include those in the intestines, bladder, stomach, blood vessels and uterus

Liposarcoma: Cancer that starts in fatty tissue

Radiation sarcoma (radiation-induced sarcoma): A rare tumor that arises after radiation therapy and differs from the original tumor treated

Undifferentiated pleomorphic sarcoma : Soft tissue tumors in which the tumor cells look different from the cells of surrounding tissue, with tumor cells growing in multiple sizes and shapes

Benign bone tumors

Benign bone tumors include noncancerous growths that start in any of the bones throughout the body. These tumors may include:

Aneurysmal bone cyst: A blood-filled growth in the bone that tends to get bigger

Chondroblastoma: A rare bone tumor that starts in the cartilage at the end of bones

Enchondroma: A rare bone tumor that starts in the cartilage inside bones

Eosinophilic granuloma: A condition in which lesions grow in bones, often in the skull, spinal bones, ribs or limbs

Fibrous dysplasia: A rare condition in which scar-like tissue grows where bone tissue should grow

Giant cell tumor of bone: Tumors that are made up of many unusually large or “giant” cells formed from the joining of several smaller cells, usually occurring at the end of a joint

Nonossifying fibroma: Bone lesions made up of scar (fibrous) tissue, commonly occurring in children

Osteochondroma: A mass of cartilage and bone that develops at the end of bones near growth plates, often in the legs, shoulder blade or pelvis

Synovial chondromatosis: A rare condition in which the synovium, the layer of tissue lining joints, grows atypically and forms small growths made of cartilage

Unicameral bone cyst: A fluid-filled cavity in a bone, usually affecting the upper arm bone (humerus) or upper leg bone (femur)

Malignant Bone Tumors

Cancerous growths that start in or spread to bones, including:

Bone marrow cancer: Cancer that starts in the bone marrow, the sponge-like tissue inside bones

Chondrosarcoma: A type of bone cancer starting in cartilage cells

Ewing sarcoma: A rare tumor starting in bones or soft tissues around bones, usually occurring in the pelvis or leg bones

Lymphoma: Cancer that starts in lymphocytes, the infection-fighting cells found in bone marrow, lymph nodes, the spleen and other parts of the body

Metastatic bone disease: Any form of cancer that starts elsewhere in the body and spreads to the bones

Myeloma: Cancer of the plasma cells, which produce infection-fighting cells called antibodies and are found in bone marrow

Osteogenic sarcoma (osteosarcoma): Cancer that starts in the bone cells, often developing at the ends of bones where new tissue forms as children grow 

Plasmacytoma: A bone tumor starting in plasma cells, possibly turning into myeloma

Treatments orthopaedic oncologists offer

Our orthopaedic oncologists are experts in a range of advanced techniques and procedures, including: 

Limb salvage and reconstruction: These procedures aim to remove tumors fully without removing an entire limb. The surgeon may remove bone surrounding the tumor and replace it with an implant to maintain the limb’s function. 

Expandable bone implants: These implants can be expanded as a child grows, without the need for reoperation. A special device uses a magnet to lengthen the implant, and patients can go home the same day as treatment.   

Mass excision: These surgeries remove soft tissue tumors. The surgeon may also remove a small portion of surrounding tissue. The mass gets sent to a lab for testing to learn more about the tumor type and function. 

Curettage: The surgeon uses an instrument called a curette to scrape away a benign bone tumor. In some cases, the bone may be able to grow back and fill in where the tumor was. For other patients, the surgeon may combine curettage with a bone graft or implant to fill in the cavity.

Amputation: Our surgeons opt for limb-sparing surgery as often as possible. But for some patients, removing part or all of a limb may be the best option for curing bone or soft tissue cancer. 

Targeted muscle reinnervation: Surgeons reassign the nerves that control muscle movements so that patients can control prosthetic limbs by thought. This procedure can be effective for reducing phantom limb pain in patients who have had amputations.

Treatment of metastatic disease: Patients may have other cancer treatments if the disease has spread (metastasized) through the body. A care plan may include one or more treatments such as chemotherapy, radiation therapy, targeted therapy or immunotherapy.
