Loose Bodies in the Elbow Joint
Loose bodies are small fragments of bone, cartilage, or other tissue that break free and float within the elbow joint, interfering with the smooth movement of the joint’s moving parts. These fragments can develop from osteoarthritis as deteriorating cartilage sheds particles into the joint space, from prior fractures or dislocations that leave behind bone chips, from osteochondritis dissecans — a condition in which a segment of bone and cartilage separates from the joint surface — or from the cumulative stress of repetitive throwing and heavy lifting. When loose bodies become trapped between the bones of the elbow joint, they can cause catching, locking, sudden sharp pain, and a progressive loss of range of motion that worsens over time. Because untreated loose bodies can also accelerate cartilage damage to the surrounding joint surface, early evaluation and treatment are important to preserve long-term function of the elbow joint.
Dr. Jonathan Glashow is a board-certified orthopedic surgeon and Clinical Associate Professor of Orthopedic Surgery at NYU Grossman School of Medicine, with fellowship training in sports medicine and arthroscopic surgery at the Southern California Orthopedic Institute/UCLA — one of the premier arthroscopy training programs in the country. Arthroscopic loose body removal requires precise visualization and instrument handling within the confined space of the elbow joint, and Dr. Glashow’s three decades of arthroscopic experience — spanning more than 15,000 procedures — make him one of the most technically proficient elbow arthroscopists in New York City. As Chief Medical Officer for the New Jersey Devils and Philadelphia 76ers, he regularly manages loose body conditions in professional athletes whose livelihoods depend on unrestricted elbow function. Named a Castle Connolly Top Doctor every year since 2000, he provides arthroscopic diagnosis and treatment of elbow loose bodies at his Upper East Side practice.
Causes and Symptoms of Elbow Loose Bodies
The elbow is a hinge and pivot joint with many moving parts. Injuries, degenerative disease and fractures may result in small fragments of bone or cartilage becoming loose in the elbow joint. Osteoarthritis is a common cause of loose bodies in the elbow as the cartilage deteriorates. Fractures and other injuries can cause fragments that float in the elbow. Athletes or others that put excessive stress on the elbows with lifting or throwing may also experience loose bodies in the elbow.
Loose bone and cartilage bodies in the elbow can interfere with the movement of ligaments, tendons and muscles in the elbow. Symptoms include pain and stiffness when bending or extending the elbow. The elbow may catch or lock during movement, with a clicking sensation when it breaks free from the restriction.
Arthroscopic Loose Body Removal in NYC
Some people are able to live with loose bodies in the elbow when the pain or dysfunction is minimal. If it does cause dysfunction or chronic pain, treatment can include removal of loose bone or cartilage from the elbow joint. Our expert orthopedic team can perform minimally-invasive arthroscopy to remove loose bodies to improve joint function and relieve pain.

Frequently Asked Questions About Loose Bodies in the Elbow
What are loose bodies in the elbow?
Loose bodies are small fragments of bone, cartilage, or connite tissue that have detached from their original location and are floating freely within the elbow joint cavity. They can range in size from tiny specks to pieces large enough to mechanically block joint movement. These fragments are sometimes called “joint mice” because they shift position within the joint, causing symptoms that come and go depending on where the loose body is sitting at any given time.
What symptoms do loose bodies cause?
The most common symptoms include intermittent catching or locking of the elbow — where the joint suddenly gets stuck mid-motion and then releases — along with sharp pain during movement, clicking or grinding sensations, swelling, and a gradual loss of the ability to fully straighten or bend the arm. Symptoms often come and go because the fragments shift position within the joint. Some patients notice that certain arm positions or activities consistently trigger episodes of locking or sharp pain while other movements feel normal.
What causes loose bodies to form in the elbow?
Loose bodies can develop from several different sources. Osteoarthritis is one of the most common causes — as the cartilage lining the joint breaks down, fragments shed into the joint space. Prior fractures or dislocations can leave behind small bone chips that become loose over time. Osteochondritis dissecans, a condition in which a segment of bone and its overlying cartilage separates from the joint surface, is another frequent cause — particularly in younger athletes. Repetitive throwing or heavy overhead use can also contribute to cartilage and bone breakdown that produces loose fragments.
How are loose bodies in the elbow diagnosed?
Dr. Glashow begins with a clinical examination that assesses range of motion, identifies points of catching or mechanical blockage, and evaluates overall joint stability. X-rays can often detect bone fragments and may reveal signs of underlying arthritis or osteochondritis dissecans. In some cases, an MRI or CT scan is used to identify cartilage fragments that do not appear on standard X-rays and to assess the condition of the surrounding joint surface. Same-day imaging is available at Dr. Glashow’s Upper East Side practice to expedite diagnosis.
How are loose bodies removed from the elbow?
The standard treatment is arthroscopic loose body removal — a minimally invasive procedure in which Dr. Glashow inserts a small camera and specialized instruments through tiny incisions to locate and extract the fragments from within the joint. During the same procedure, he can also assess and address any associated damage to the cartilage surface, smooth rough areas, and remove bone spurs that may be contributing to fragment formation. Arthroscopic removal is performed on an outpatient basis and allows for a significantly faster recovery than traditional open surgery.
What is recovery like after arthroscopic loose body removal?
Most patients begin gentle range-of-motion exercises within the first few days after surgery, and many return to daily activities within one to two weeks. Because the procedure is minimally invasive with small incisions, post-operative pain and swelling are typically modest. A structured physical therapy program helps restore full range of motion and strength over the following weeks. Most patients return to sports or physically demanding work within four to eight weeks, depending on the extent of any additional joint work performed during the procedure. Dr. Glashow monitors each patient’s progress closely and adjusts the rehabilitation timeline based on individual healing.
