For an orthopedic swelling, take the history in a structured way to decide whether it is traumatic, inflammatory/infective, degenerative, vascular, congenital, or neoplastic.
Questions to ask and why
| What to ask | Why it matters |
|---|---|
| Where exactly is the swelling? Is it over a joint, bone, muscle, tendon, bursa, or soft tissue? | The site narrows the likely origin. For example, a swelling over the patella may be prepatellar bursitis; near a joint may be effusion or synovial swelling; fixed to bone can suggest a bony lesion. |
| When did you first notice it? | Acute swelling suggests trauma, bleeding, acute infection, or acute inflammation. A slow, long-standing swelling is more often benign, chronic infection, or a benign tumor. |
| How did it start? Sudden or gradual? | Sudden onset can occur with injury, hemarthrosis, abscess, or acute osteomyelitis. Gradual onset suggests chronic disease or tumor. |
| Is it increasing in size? How fast? | Rapid growth is concerning for infection, hemorrhage, or malignancy. Slow stable growth favors benign causes, though all persistent enlarging masses require assessment. |
| Was there trauma before it appeared? Fall, road traffic collision, sports injury, twist, direct blow, minor injury? | Trauma may cause hematoma, fracture-related swelling, ligament injury, or joint effusion. But do not assume trauma explains the mass: it may merely draw attention to a pre-existing tumor. |
| Was there a wound, injection, surgery, bite, or recent procedure nearby? | Raises the possibility of infection, foreign body, postoperative seroma/hematoma, or abscess. |
| Is there pain? Ask onset, severity, character, night pain, and relation to movement or weight-bearing. | Throbbing pain with warmth suggests inflammation/infection. Mechanical pain with activity suggests joint or tendon pathology. Persistent rest pain or night pain is a tumor and infection red flag. |
| Did pain begin before the swelling? | Pain before a bony swelling can be seen in some malignant bone lesions. In many benign masses, swelling may be painless initially. |
| Is the swelling tender, hot, or red? | Suggests acute inflammation, cellulitis, abscess, septic arthritis, bursitis, or osteomyelitis. |
| Does it vary in size? For example, after activity, standing, coughing, or during the day? | Activity-related enlargement may indicate joint effusion or bursitis. Change with dependency can suggest venous/vascular causes. A mass that changes with coughing or straining may have a communicating component. |
| Any fever, chills, malaise, anorexia, or recent infection? | Supports infection. Ask about recent skin infection, sore throat, urinary infection, diarrhea, dental infection, or tuberculosis contact when relevant. |
| Any discharge, ulceration, or sinus? Has anything like a bone fragment come out? | A chronic draining sinus suggests chronic osteomyelitis, including pyogenic or tuberculous infection. |
| Any stiffness, restricted movement, locking, instability, or inability to bear weight? | Determines joint involvement and functional severity. Painful restriction plus fever and a hot swollen joint needs urgent exclusion of septic arthritis. |
| Any numbness, tingling, weakness, coldness, or color change distal to the swelling? | Looks for nerve compression or vascular compromise, which can require urgent intervention. |
| Any previous similar swelling or recurrence after treatment? | May indicate recurrent ganglion, bursitis, chronic infection, inflammatory disease, or tumor recurrence. |
| Any swelling elsewhere or pain in other joints? | Helps identify systemic inflammatory arthritis, gout, rheumatoid disease, multifocal tumors, or generalized edema. |
| Any weight loss, loss of appetite, fatigue, or night sweats? | These are red flags for malignancy, tuberculosis, or chronic infection. |
| Past history: TB, diabetes, gout, rheumatoid arthritis, bleeding disorder, cancer, kidney/liver disease, immunosuppression? | These conditions alter the differential diagnosis. Diabetes and immunosuppression increase infection risk; gout causes episodic joint swelling; cancer history raises concern for metastasis. |
| Drug history: anticoagulants, antiplatelets, steroids, immunosuppressants? | Anticoagulants can cause hematoma or hemarthrosis; steroids and immunosuppressants increase infection risk. |
| Family history: tumors, neurofibromatosis, bleeding disorders, inflammatory arthritis? | May reveal inherited predispositions. |
| Occupation, sports, repetitive kneeling/pressure, and functional impact? | Repetitive use can cause bursitis and tendinopathy. Functional limitation helps assess severity and plan treatment. |
Key red-flag questions
Ask specifically about:
- Rapidly enlarging swelling
- Deep swelling or one fixed to bone
- Size more than about 5 cm
- Persistent pain at rest or night pain
- Unexplained weight loss, fever, or night sweats
- Hot, very painful joint with fever or inability to bear weight
- Numbness, weakness, absent pulses, cold distal limb
- Open wound, purulent discharge, or chronic sinus
These findings need urgent clinical assessment, imaging, and sometimes referral to an orthopedic tumor or infection service.
Simple examination-case format
You can present it as:
“The swelling began ___ ago, was sudden/gradual in onset, followed trauma/no trauma, and is progressively increasing/not increasing. It is painful/painless, with pain described as ___. There is associated fever/redness/discharge/restriction of movement/constitutional symptoms. There is or is not a past history of similar swelling, infection, tuberculosis, inflammatory arthritis, gout, malignancy, surgery, or anticoagulant use.”
For bone swellings specifically, trauma can coexist with osteomyelitis or a tumor and should not automatically be assumed to be the cause. Acute fever and toxicity favor acute osteomyelitis; rapid growth and a relatively short history can occur with malignant bone tumors. Pain character also helps, with throbbing pain favoring inflammation. S Das A Manual on Clinical Surgery, 13th ed., p. 151.
