Hand & Upper Extremity
Infections
Jacksonville, FL

Hand infections range from minor nail fold irritation to surgical emergencies that can permanently destroy tendon function within hours. Knowing the difference — and acting on it — is everything. Dr. Graham treats every infection of the upper extremity, from paronychia to necrotizing fasciitis, urgently when needed.

Go to the ED Immediately If You Have
  • A finger held bent that is exquisitely painful to straighten — possible flexor tenosynovitis
  • Redness spreading up the forearm from a hand wound
  • A laceration over the knuckle after a fight or altercation
  • Severe hand swelling with fever and inability to move fingers
  • A rapidly spreading skin infection with dark discoloration or blistering

For urgent infections on clinic days (Tue · Wed · Fri), JOI Now walk-in may be appropriate. When in doubt, call first.

⚠️
Critical Warning — Most Underestimated Hand Injury
Fight Bite: A Small Cut Over the Knuckle Is Not a Minor Injury

A laceration over the MCP joint (knuckle) sustained during a fight or altercation inoculates the joint with oral bacteria — including Eikenella corrodens, which is resistant to many standard antibiotics. These injuries are routinely dismissed at urgent care and sent home with oral antibiotics. By the time the patient arrives in the OR, the joint is often septic and cartilage destruction is already underway. Any laceration over the knuckle after a punch must be evaluated by a hand surgeon the same day. The size of the cut is irrelevant. The location is everything.

Time Is Tissue.
Especially in the Hand.

The hand has very little tissue between the skin and the structures that matter — tendons, nerves, joints, and bone are all within millimeters of the surface. An infection that might be a nuisance in the thigh or back can destroy a flexor tendon sheath in 24–48 hours. The same anatomy that makes the hand a marvel of precision makes it acutely vulnerable to infection spreading along fascial planes and tendon sheaths.

Dr. Graham treats every infection of the upper extremity — finger, hand, wrist, forearm, elbow, and shoulder. Most common infections are straightforward: drain the abscess, culture the organism, target the antibiotic. The ones that require judgment are the ones that look worse than they are, or — more dangerously — the ones that look better than they are. A fight bite with a 5mm laceration. A puncture wound from a palm frond that "didn't go that deep." A finger that's a little swollen with a line of tenderness along the flexor sheath.

Jacksonville's outdoor lifestyle means Dr. Graham also sees a steady volume of foreign body infections — palm frond punctures, cactus spines, fishing hooks, wood splinters, and plant material that tracked deep into tissue. These require surgical removal and targeted antibiotic coverage that generic urgent care management often misses.

Not every infection needs surgery. Early paronychia, cellulitis without abscess, and mild soft tissue infections often respond to antibiotics alone — oral or IV depending on severity. Surgery is needed for discrete abscesses, infections inside tendon sheaths or deep spaces, retained foreign bodies, and infections failing antibiotic management. Every patient gets an honest assessment of what is actually required.
Infection Urgency Guide
Hand infections vary dramatically in how quickly they must be treated.
🚨
Emergency — ED Now

Flexor Tenosynovitis

Four Kanavel signs: finger in flexion, fusiform swelling, sheath tenderness, pain with passive extension. Surgical washout within hours — tendon function is at stake.

⚠️
Same Day — Hand Surgeon

Fight Bite / Human Bite Over Knuckle

Always a same-day hand surgery evaluation regardless of wound size. The joint is likely inoculated. Do not wait.

🔥
Same Day — Possible ED

Deep Space & Necrotizing Infection

Spreading redness, fever, firmness out of proportion to skin findings, dark discoloration or blistering — ED immediately for necrotizing infections.

⏱️
Prompt — Within 24 Hours

Felon & Established Abscess

Throbbing fingertip pulp pain with tense swelling — abscess that needs drainage. Prompt but not necessarily midnight ED visit.

🩹
Clinic Visit

Paronychia, Foreign Body, Onychomycosis

Early nail fold infections, retained plant material or spines, nail fungus — evaluated and managed at a scheduled or walk-in clinic visit.

The Four Kanavel Signs — Know These Before You Need Them
  • Finger held in slight flexion at rest
  • Fusiform (sausage-like) swelling of the entire finger
  • Tenderness along the flexor tendon sheath
  • Severe pain with passive extension of the finger

All four present = flexor tenosynovitis until proven otherwise. Go to the emergency department immediately. Do not wait for a clinic appointment.

Jacksonville Coastal Warning — Vibrio Vulnificus
Oyster Cuts & Saltwater Wounds Can Kill — Especially If You Are Immunocompromised

Vibrio vulnificus is a naturally occurring bacterium in Gulf Coast and Atlantic saltwater — present in oysters, fish, and seawater year-round in Northeast Florida. A laceration from an oyster shell, a puncture from a fish spine, or even contact between saltwater and an open wound can introduce Vibrio into tissue.

In healthy individuals, Vibrio causes a painful, rapidly progressing wound infection that requires aggressive surgical debridement and specific antibiotic coverage — doxycycline plus a third-generation cephalosporin or fluoroquinolone. Standard wound infection antibiotics are not adequate.

In patients who are immunocompromised — liver disease, diabetes, cancer, HIV, chronic kidney disease, or taking immunosuppressants — Vibrio vulnificus can cause necrotizing fasciitis and sepsis within 24–48 hours. Mortality in high-risk patients exceeds 50%. Any saltwater wound in an immunocompromised patient is a medical emergency. Go to the ED immediately — do not wait and watch.

Bone & Implant Infections
🦴
Osteomyelitis
Bone infection — acute from direct inoculation after open fracture or surgery, or chronic. Requires debridement of infected bone, culture-directed antibiotics, and often staged reconstruction.

Infections Managed
by a Hand Surgeon

Hand infections treated by surgeons who understand the anatomy produce better outcomes than those managed by general practitioners alone. Here's what that means in this practice.

01

The Full Spectrum — Finger to Shoulder

Every infection of the upper extremity is within scope — paronychia, felon, flexor tenosynovitis, deep space infections, fight bites, animal bites, foreign body infections, marine infections, septic joint, osteomyelitis, necrotizing fasciitis, and periprosthetic infections. Referrals from the ED, urgent care, and other physicians are accepted urgently when needed.

02

Jacksonville Foreign Bodies

Palm fronds, cactus spines, fishhooks, and plant material are a routine part of this practice — not unusual presentations. Retained plant material introduces organisms and stimulates an inflammatory response that does not resolve with antibiotics alone. Surgical removal under direct visualization is the only reliable treatment, and Dr. Graham performs this regularly.

03

Fight Bites Taken Seriously

A 5mm laceration over the knuckle after a fight is a potential joint infection. Dr. Graham evaluates and manages these same-day. Surgical exploration of the joint, thorough irrigation, and targeted antibiotic coverage — not a prescription for oral antibiotics and a follow-up appointment in a week.

04

Not Every Infection Needs the OR

Early paronychia, cellulitis without abscess, and minor soft tissue infections often respond to antibiotics and local wound care. Dr. Graham evaluates each infection for what it actually requires — avoiding unnecessary surgery and unnecessary delay in equal measure. The standard is appropriate treatment, not reflexive escalation.

05

Periprosthetic & Hardware Infections

Referred periprosthetic and hardware infection cases are accepted — whether the original surgery was done here or elsewhere. Management requires understanding the implant, the organism, the host, and the staging options. These are complex cases that benefit from a surgeon who performs the full range of upper extremity reconstruction.

06

Urgent Access When It Matters

Flexor tenosynovitis and fight bites do not wait for a standard appointment slot. Dr. Graham's office accommodates urgent infection referrals on clinic days, and coordinates with the emergency department for cases requiring same-day surgical intervention. JOI Now walk-in is available for infections that don't need the ED.

"Roy Williams said if there were 10 stars available he would give Dr. Graham 10. The outcome exceeded every expectation."

Frequently Asked Questions

The most important pattern to recognize is flexor tenosynovitis — the four Kanavel signs: the finger held in slight flexion at rest, fusiform (sausage-like) swelling of the entire finger, tenderness along the flexor tendon sheath on the palm side, and severe pain with passive extension of the finger. All four together is a surgical emergency. Other signs of serious infection requiring urgent evaluation include redness spreading up the forearm from a hand wound, fever with severe hand swelling, firmness deep in the palm, and any laceration over the knuckle after a fight.
A laceration over the MCP joint from striking someone's teeth inoculates the joint with oral bacteria — including Eikenella corrodens, which is resistant to many first-line antibiotics and causes particularly aggressive joint destruction. The injury looks small on the outside but the fist was clenched at impact, driving the tooth deep into the joint capsule. When the fist opens, the skin shifts and covers the joint puncture, making the communication invisible. These injuries are routinely undertreated at urgent care. By the time patients arrive for proper surgical treatment, joint cartilage is often already damaged. Same-day hand surgery evaluation is required regardless of wound size.
No. Early paronychia, cellulitis without abscess, and mild soft tissue infections often respond to antibiotics alone. Surgery is needed when there is a discrete abscess requiring drainage, infection inside a tendon sheath or deep space, a retained foreign body that must be removed, or an infection not responding to appropriate antibiotics. Dr. Graham evaluates each infection individually and recommends the least invasive effective treatment — neither reflexively operating nor reflexively sending patients home with antibiotics that won't work.
It depends on depth, location, and how it's responding. Retained plant material — palm fronds, cactus spines, rose thorns — introduces organisms and stimulates inflammation that antibiotics alone cannot resolve. If the wound is on the hand or finger and is getting more painful or swollen despite treatment, or if you can feel retained material, a hand surgeon should evaluate it promptly. Surgical removal under direct visualization is often required. Standard urgent care antibiotics are frequently inadequate because the material itself is the problem, not just the bacteria.
Herpetic whitlow is a herpes simplex virus infection of the fingertip — presenting with vesicles, burning pain, and swelling that can look superficially similar to a bacterial felon. The critical distinction is that herpetic whitlow must not be incised and drained — doing so worsens the infection and risks spreading virus. The diagnosis is clinical: grouped vesicles, prodromal tingling, and a history of herpes exposure. It is treated with antiviral medication, not drainage. Incising what turns out to be herpetic whitlow is one of the more avoidable errors in hand infection management — which is exactly why it belongs on this page even as a rare presentation.
Yes — take it seriously. Saltwater wounds in Northeast Florida carry risk of Vibrio vulnificus, a bacterium present in coastal and Gulf waters year-round. In otherwise healthy individuals, Vibrio causes a rapidly progressing wound infection that requires specific antibiotic coverage — doxycycline combined with a third-generation cephalosporin or fluoroquinolone. Standard wound antibiotics won't cover it adequately. Clean the wound thoroughly, seek medical attention promptly, and make sure the treating provider is aware it was a saltwater injury so the right antibiotics are chosen. In patients who are immunocompromised — liver disease, diabetes, cancer, HIV, chronic kidney disease, or immunosuppressant medications — Vibrio vulnificus can cause necrotizing fasciitis and life-threatening sepsis within 24–48 hours. If you are immunocompromised and have a saltwater wound, go to the emergency department immediately, not the urgent care. This is not an overreaction — mortality in high-risk patients exceeds 50%.
Yes. Periprosthetic infections and infected hardware after upper extremity surgery are accepted whether the original procedure was performed here or elsewhere. Management depends on the organism, implant stability, patient host factors, and staging strategy. Bring prior operative reports, imaging, and any culture results to the consultation. These cases require coordination between orthopaedic surgery and infectious disease, and Dr. Graham manages that coordination.

Hand infection?
Don't wait to find out what it is.
