Ointments/topical treatments for bruises

• Diclofenac gel (1%) - a topical NSAID gel specifically indicated for short-term treatment of pain from minor strains, sprains, and bruises (Goodman & Gilman's Pharmacological Basis of Therapeutics, p. 861). It reduces the pain and inflammation associated with a bruise, though it doesn't dramatically speed clearance of the discoloration itself. Avoid on broken skin.
• Arnica montana gel - widely used over-the-counter for bruising; some clinical studies (mostly post-surgical/cosmetic procedure settings) show modest reduction in bruise severity and faster fading when applied to intact skin. Evidence is mixed/modest rather than strong. Avoid if you're on blood thinners (warfarin, heparin, DOACs) since arnica itself has mild anticoagulant-like effects.
• Topical vitamin K (oxide) cream - some evidence it hastens resolution of bruising/purpura, often marketed for post-procedure or post-cosmetic bruising.
• Heparinoid gels (e.g., heparin sodium-containing creams, common in Europe) - used for bruise/hematoma resorption, thought to have mild anti-inflammatory and anticoagulant topical effects, though robust trial data is limited.
• Aloe vera gel - soothing, some evidence for mild benefit, very low risk.
• Antibiotic ointment is NOT needed for a closed bruise since there's no open wound - that's only for abrasions/lacerations where skin is broken.

• Ice/cold packs for the first 24-48 hours (reduces bleeding into tissue and swelling)
• Elevation of the area if a limb
• Gentle compression
• After 48 hours, gentle warmth may help reabsorption

Leg contusion with pain - what to check first

• Compartment syndrome - this is the main thing not to miss with leg contusions, especially after a direct blow/crush. Watch for the "5 Ps": Pain out of proportion to the injury (especially with passive stretch of the muscle), Pallor, Paresthesia, Pulselessness, Paralysis. A tense, swollen, tight-feeling leg with escalating pain despite analgesia is an emergency - needs immediate ED evaluation, not ointment (Rosen's Emergency Medicine).
• Fracture - point tenderness over the tibia/fibula, inability to bear weight, or deformity suggests a fracture rather than a simple contusion. In older patients, contusion near the hip/thigh with difficulty on straight-leg raise can point to a femoral neck fracture (Bailey & Love's Short Practice of Surgery).
• DVT - if the bruise wasn't from an obvious direct blow, or if there's associated calf swelling/warmth/redness disproportionate to a bruise, especially in someone with risk factors (immobility, recent surgery, clotting disorder), DVT should be considered.

• Pain is proportional to the visible bruise, no numbness/tingling, can move the joint and bear weight, no point bone tenderness.
• Management: RICE - Rest, Ice (first 24-48 hrs, 15-20 min sessions), Compression (light elastic wrap, not tight), Elevation.
• Pain/inflammation control: oral NSAIDs (ibuprofen) or acetaminophen; topical diclofenac 1% gel is specifically indicated for pain from minor bruises/strains/sprains if the skin is intact.
• Arnica gel can be added for modest cosmetic/symptomatic benefit but isn't a substitute for the above.
• Avoid massaging the area early on (can worsen bleeding into tissue).

Recommended next steps

• A contusion overlying bone with point tenderness and inability to weight-bear can mask an underlying fracture - the bruising and swelling are the soft-tissue response, but the bone itself may be broken.
• In older patients, contusion over the hip/thigh region with difficulty on straight-leg raise specifically raises concern for a femoral neck fracture - this is a classic exam pearl.
• Even a nondisplaced tibial/fibular stress or shaft fracture can present with what looks like "just a bad bruise" plus pain, especially if the trauma was direct (kick, fall, blunt object).

1. Do not bear weight on the leg until fracture is excluded.
2. Splint/immobilize temporarily if transport is needed.
3. Get an X-ray of the tibia/fibula (and hip/femur if tenderness is more proximal) to rule out fracture.
4. Ice, elevate, and use oral analgesia (NSAIDs/acetaminophen) in the meantime - hold off on vigorous massage or heat.
5. Also check distal pulses, sensation, and whether the compartment feels tense - if pain is severe/escalating and out of proportion, that raises concern for compartment syndrome, which is a surgical emergency and takes priority over everything else.

1. Point tenderness over bone + inability to bear weight = fracture criteria, regardless of how "minor" the mechanism seems. A stick can absolutely cause a tibial or fibular fracture, especially a direct linear blow (classic "nightstick fracture" of the ulna is the arm equivalent - the same mechanism applies to the tibia in the leg: a direct blow against a subcutaneous long bone with little soft tissue cushioning).
2. Age 60 matters. Bone density starts declining meaningfully in this decade, particularly in postmenopausal women but also in men. Textbook teaching is explicit: "the most trivial trauma may result in bruising ... fracture" in older patients due to age-related osteoporosis/bone fragility (Parikh's Forensic Medicine; Tintinalli's Emergency Medicine). A blow that might just bruise a 25-year-old can fracture a 60-year-old's tibia/fibula.
3. 4 days with persistent inability to bear weight is not consistent with a simple contusion. A straightforward bruise typically allows at least partial weight-bearing within a day or two, with pain steadily improving. Persistent non-weight-bearing at day 4 strongly suggests an undiagnosed fracture (commonly a non-displaced fibular or tibial fracture) rather than soft tissue injury alone. This pattern is exactly how fractures get missed and mismanaged as "just a bruise."
4. A normal-looking bruise does NOT rule out fracture. Bone bruise and even nondisplaced fractures often look identical to a soft-tissue contusion externally - X-ray is the only way to differentiate reliably.

• Get an X-ray of the tibia/fibula (whole leg if tenderness location is unclear) - this should have been done at presentation, and 4 days of continued non-weight-bearing makes it more urgent, not less.
• Until imaged, treat as a possible fracture: avoid weight-bearing, splint/immobilize if possible, elevate, ice, oral analgesia (paracetamol/NSAID if no contraindication).
• If X-ray is negative but pain/non-weight-bearing persists beyond another few days, consider MRI for occult fracture or bone bruise, and reassess for missed radiographic findings (missed fractures on plain film are a recognized ED pitfall, especially subtle non-displaced ones).
• No indication for surgical/emergency compartment syndrome workup based on what you've described ("others normal" - no neurovascular signs) - that risk is low now, 4 days out, if pulses/sensation are intact.

Management for this case (day 4, simple leg contusion)

• Topical diclofenac 1% gel - apply thin layer 3-4x/day over the bruised area (skin must be intact, no open wound). This is specifically indicated for pain from bruises and reduces local inflammation.
• Heparinoid or arnica gel as an alternative/adjunct if NSAID gel isn't tolerated - helps hematoma resorption and may reduce discoloration duration, though evidence is modest.
• Avoid heat right at day 4 if there's still visible swelling; warm compress is more useful once swelling has settled (usually day 3-5 onward) to improve blood flow and speed reabsorption of the bruise pigment. Cold packs are more for the acute (first 48h) phase.

• Oral analgesia if pain is bothersome: paracetamol is first-line at age 60; oral NSAID (ibuprofen) can be added short-term if no renal impairment, GI ulcer history, or anticoagulant use - worth checking these before recommending NSAIDs given the patient's age.
• Gentle mobilization - avoid strict rest; light movement helps prevent stiffness, but avoid strenuous use of the leg until pain settles.

• New numbness, tingling, or weakness
• Increasing swelling, tightness, or pain rather than gradual improvement
• Skin changes (spreading redness, warmth suggesting infection, or skin breakdown over the hematoma)
• The bruise itself will typically go through color changes (red/purple to green/yellow) over 1-3 weeks as it resolves - this is normal and not a sign of worsening.

• If pain or swelling is not gradually improving by day 7-10
• If the bruise seems to be enlarging rather than fading
• If the patient is on anticoagulants/antiplatelets (important to ask, as this can cause larger-than-expected hematomas and slower resolution, especially at age 60)
