Quick answer: Subungual Hematoma Nail Trephination Nail Loss Guide is a common nail condition with multiple causes including trauma, fungal infection, biomechanical pressure, and underlying medical conditions. Treatment depends on the cause: trauma resolves as the nail grows out (6-12 months), fungus needs antifungal therapy, and biomechanical issues need shoe and orthotic correction. Call (810) 206-1402.

A subungual hematoma — bleeding beneath the nail plate from direct trauma, repetitive microtrauma from running, or crushing injury — is one of the most painful acute nail conditions encountered in podiatric practice. Appropriate management depends on hematoma size, time elapsed since injury, and whether nail plate disruption warrants exploration for underlying nail bed laceration.
Mechanisms of Injury
Acute subungual hematoma results from direct impact (dropping a heavy object, kicking a fixed object) that ruptures the subungual blood vessels between the distal phalanx and the nail plate. Repetitive microtrauma hematoma — “runner’s toe” or “black toenail” — accumulates gradually from the nail plate impacting the toe box with each footstrike, particularly in shoes with inadequate toe box depth or during prolonged downhill running that drives the toes forward. The great toenail and second toenail are most commonly affected.
When to Trephinate
Trephination (decompression of the hematoma by creating a small hole through the nail plate) is indicated when: hematoma covers more than 25–50% of the nail plate area, pain is severe, and presentation is within 48 hours of acute injury before clot organization. The procedure uses a heated wire (electrocautery), rotary drill, or 18-gauge needle to create a small opening through the nail plate over the hematoma — releasing the accumulated blood and immediately relieving pressure and pain. Post-trephination care includes cleansing, protective dressing, and daily wound inspection for infection signs. Trephination is unnecessary for small hematomas (<25%) or those older than 48–72 hours, where observation and nail protection are appropriate.
Nail Plate Disruption and Nail Bed Laceration
Complete nail avulsion at the time of injury requires exploration of the nail bed for laceration — particularly for injuries with hematoma involving more than 50% of the nail area, which has a high correlation with underlying nail bed laceration. Nail bed lacerations are repaired with 6-0 absorbable suture to restore the smooth nail bed surface that guides normal nail regrowth. The original nail plate is replaced as a biological splint over the repair or a non-adherent nonadherent dressing is used if the original plate is damaged beyond reuse.
Nail Regrowth and Prognosis
Toenail regrowth following complete nail loss proceeds at approximately 1–1.5mm per month from the nail matrix — requiring 12–18 months for complete great toenail regrowth. Patients should expect nail plate dystrophy (ridging, thickening, color change) in the new nail during the regrowth period. Permanent nail dystrophy results from nail matrix damage — a risk with severe crush injuries, deep lacerations involving the matrix, or repeated trauma to the same nail. Protective nail splints and wider toe box footwear during regrowth prevent repeated microtrauma during the vulnerable period.

Frequently Asked Questions
How long does it take a toenail to grow back?
6-12 months for a full big toenail. Smaller toenails 4-6 months. Speed varies with age, circulation, and nutrition.
Will this affect other nails?
Trauma affects only the injured nail. Fungal infection can spread without treatment. Systemic causes affect multiple nails simultaneously.
Should I cover the nail or leave it open?
Cover with a breathable bandage during work or activity. Leave open at night for healing. Keep dry and clean.
What is Foot pain?
Foot pain is a common foot/ankle condition that affects mobility and quality of life. Understanding the underlying cause is the first step in successful treatment. Our podiatrists at Balance Foot & Ankle perform a hands-on biomechanical exam, review your activity history, and use diagnostic imaging when appropriate to identify the root cause—not just treat the symptom. Many patients have been told to “rest and ice” without a deeper diagnostic workup; our approach is different.
Symptoms and warning signs
Common signs of foot pain include pain that worsens with activity, morning stiffness, swelling, tenderness when palpated, and difficulty bearing weight. If you experience sudden severe pain, inability to walk, visible deformity, numbness or color change, contact our office the same day or visit urgent care—these can signal a more serious injury such as a fracture, tendon rupture, or vascular compromise. Diabetics with any foot wound should seek same-day care.
Conservative treatment options
Most cases of foot pain respond to non-surgical care: structured rest, supportive footwear changes, custom orthotics, targeted stretching and strengthening protocols, anti-inflammatory medications when medically appropriate, and in-office procedures such as ultrasound-guided injections. We also offer advanced therapies including MLS laser therapy, EPAT/shockwave, regenerative injections, and image-guided procedures. Treatment is sequenced from least invasive to most invasive, and we explain the rationale at every step.
When is surgery considered?
Surgery is reserved for cases that fail 3-6 months of well-structured conservative care, when there is structural pathology (severe deformity, complete tear, advanced arthritis), or when imaging shows damage that will not heal without intervention. Our surgeons have performed 3,000+ foot and ankle procedures and prioritize minimally-invasive techniques whenever appropriate. We discuss recovery timelines, return-to-activity milestones, and realistic outcome expectations before any procedure is scheduled.
Recovery timeline and prevention
Recovery from foot pain varies based on severity and chosen treatment path. Conservative cases often improve within 4-8 weeks with consistent adherence to the protocol. Post-procedural recovery may range from a few days (in-office procedures) to several months (reconstructive surgery). Long-term prevention involves footwear assessment, activity modification, structured strengthening, and regular check-ins with your podiatrist if you have a history of recurrence. We provide written home-exercise plans and digital follow-up support.
