How to Apply an Elastic Bandage for Ankle Sprain
Ankle sprains are the most common sports injury, accounting for 15-30% of all sports injuries (Fong et al., Sports Medicine, 2007). Proper bandaging in the acute phase controls swelling, provides support, and facilitates early mobilization.
When to Bandage vs When to Seek Medical Care
Bandaging is appropriate for Grade I-II sprains (mild-moderate ligament stretch, no gross instability). Seek immediate medical evaluation if:
- Unable to bear ANY weight (possible fracture)
- Visible deformity of the ankle
- Severe swelling within minutes (hemarthrosis — possible complete ligament rupture)
- Numbness or inability to move toes
- Positive Ottawa Ankle Rules: tenderness at posterior edge of lateral/medial malleolus OR inability to walk 4 steps
Step-by-Step: Figure-8 Bandaging Technique
Supplies needed: 7.5-10cm (3-4 inch) elastic bandage, 2 bandage clips or cohesive tape.
Patient position: Foot held at 90 degrees to leg (neutral position) — NOT pointed (plantarflexion), as this creates a loose bandage when the patient stands.
- Start at the ball of the foot: Anchor the bandage with 2 circular turns around the metatarsal heads (widest part of the forefoot, just behind the toes). Apply with minimal tension — just enough to hold.
- Diagonal wrap upward: Angle the bandage diagonally across the top (dorsum) of the foot toward the ankle. The bandage crosses from the little toe side toward the inside of the ankle.
- Circle the ankle: Wrap around the back of the Achilles tendon and across the front of the ankle, creating a circular turn around the ankle joint. This turn anchors the diagonal wrap.
- Diagonal down: Angle the bandage back down across the top of the foot in the OPPOSITE diagonal direction (crossing over the previous diagonal to form a figure-8).
- Alternate directions: Continue alternating upward and downward diagonal turns, each overlapping the previous turn by 50%. Each figure-8 loop covers more of the foot and ankle.
- Cover the heel: Ensure the bandage wraps around the heel — the heel must be included to prevent the bandage from sliding up. The heel lock is key to bandage stability.
- Finish on the lower leg: After 3-4 figure-8 loops, end with 2-3 circular turns around the lower leg, ending well above the ankle joint (8-10cm above the malleoli).
- Secure: Fasten with bandage clips or a strip of tape. Do NOT use metal clips next to skin — always place padding underneath.
Compression Check After Application
- Capillary refill on all toes: <2 seconds
- Skin color: normal pink (not pale, not dusky)
- Two-finger test: can slide 2 fingers under top edge of bandage
- Patient can wiggle toes freely without pain or tingling
- Bandage feels "firm like a handshake" — not "tight like a tourniquet"
Common Mistakes
| Mistake | Consequence | Correction |
|---|
| Wrapping too tightly | Ischemia, nerve compression, pain | Start loose, tighten gradually. Check toes every 2 hours |
| Not including the heel | Bandage slides up, becomes loose within minutes | Every diagonal turn must wrap behind the heel |
| Foot held pointed during application | Bandage becomes loose when standing (foot at 90 degrees) | Hold foot at neutral 90-degree angle |
| Uneven tension (tight spots) | Pressure points, skin damage, inconsistent compression | Maintain even tension; overlap turns evenly |
| Covering toes | Cannot assess circulation — dangerous | Leave toes fully exposed for neurovascular checks |
| Circular turns only (no figure-8) | Poor ankle coverage, slides off easily | Use figure-8 technique — alternates support angles |
Care Schedule
- First 48 hours: Keep bandage on continuously (except for hygiene). Re-wrap every 8-12 hours as swelling changes. Use alongside RICE protocol: Rest, Ice (20 min on/2 hours off), Compression (bandage), Elevation.
- 48-72 hours: May remove for short periods. Continue compression during daytime activities.
- After 72 hours: Transition to functional support (ankle brace or sports tape) for activity. Bandage at night only if swelling persists.
