Ankle & Lower Leg
Ankle Arthritis
Ankle arthritis can be managed conservatively for years - and when it cannot, modern reconstruction and fusion procedures restore function. Dr. O'Carroll walks you through every option.

Where does it hurt?
The foot is powerful, complex, and highly connected. Start with where it hurts, then explore the conditions Dr. O'Carroll treats most often in that region.
Ankle & Lower Leg
Sprains, instability, arthritis, fractures, and lower-leg wounds.
Ankle & Lower Leg
Ankle Fractures
From hairline malleolar fractures to complex trimalleolar and pilon injuries - Dr. O'Carroll provides accurate diagnosis, anatomic reduction, and a recovery plan that protects long-term ankle function.
Ankle & Lower Leg
Ankle Sprains & Ligament Injuries
From routine inversion sprains to high-grade ligament tears - Dr. O'Carroll diagnoses ankle injuries thoroughly so you don't end up with chronic instability.
Ankle & Lower Leg
Foot & Ankle Tendonitis
Tendonitis isn't one diagnosis - it's a family of overuse injuries affecting the Achilles, posterior tibial, peroneal, and other tendons of the foot and ankle. Dr. O'Carroll diagnoses the specific tendon involved and tailors treatment to it.
Ankle & Lower Leg
Lower Leg Wounds & Ulcers
Venous, arterial, and mixed-etiology lower-leg wounds need a clear diagnosis and a coordinated plan. Dr. O'Carroll provides advanced wound care across the Central Coast.
Heel & Achilles
Plantar fasciitis, Achilles disorders, and posterior heel conditions.
Heel & Achilles
Achilles Tendon Injuries
From insertional tendinopathy to acute rupture - Dr. O'Carroll provides a full spectrum of Achilles care, with surgical and non-surgical pathways tailored to your activity goals.
Heel & Achilles
Heel Bone Spurs
Heel spurs are common - but they're usually a finding, not a diagnosis. Learn what spurs really mean and when removal is actually warranted.
Heel & Achilles
Plantar Fasciitis & Heel Pain
The most common cause of heel pain in adults. Learn what really causes it, what actually works, and when surgery is the right call - from Central Coast podiatric surgeon Dr. Brian O'Carroll.
Midfoot & Rearfoot
Flatfoot, midfoot arthritis, soft-tissue lesions, and tarsal injuries.
Midfoot & Rearfoot
Bone Cysts & Tumors
Most bone cysts and tumors of the foot and ankle are benign - but they need accurate diagnosis. Dr. O'Carroll provides imaging, biopsy when indicated, and definitive treatment.
Midfoot & Rearfoot
Flat Feet & Posterior Tibial Tendon Dysfunction
Adult-acquired flatfoot is a progressive condition driven by failure of the posterior tibial tendon. Caught early, it's very treatable. Caught late, it requires reconstruction.
Midfoot & Rearfoot
Ganglion Cysts
A ganglion cyst is a benign, fluid-filled lump that arises from a joint or tendon sheath. Most are easily managed - but accurate diagnosis matters.
Midfoot & Rearfoot
Midfoot & Rearfoot Wounds
Wounds at the midfoot and heel - particularly in patients with diabetes or neuropathy - require expert evaluation and offloading. Dr. O'Carroll provides comprehensive wound care.
Midfoot & Rearfoot
Midfoot Arthritis
Midfoot arthritis is often missed for years. Dr. O'Carroll diagnoses and treats midfoot joint disease with a clear conservative-first plan and selective fusion when needed.
Midfoot & Rearfoot
Tarsal Fractures
Fractures of the tarsal bones - calcaneus, talus, navicular, cuboid, cuneiforms - are serious injuries. Accurate reduction and fixation prevent long-term arthritis and deformity.
Toe & Forefoot
Bunions, hammertoes, neuromas, ingrown nails, and forefoot reconstruction.
Toe & Forefoot
Bunions (Hallux Valgus)
A bunion is more than a bump - it's a 3D deformity of the first metatarsal. Dr. O'Carroll is a trained Lapiplasty® surgeon offering modern bunion correction.
Toe & Forefoot
Diabetic Foot Wounds & Ulcers
A diabetic foot ulcer is a medical emergency in slow motion. Dr. O'Carroll provides expert wound care, offloading, and limb salvage across the Central Coast.
Toe & Forefoot
Forefoot Abscesses & Infections
Soft-tissue and bone infections of the forefoot - particularly in patients with diabetes - require urgent expert care to prevent spreading infection and save the foot.
Toe & Forefoot
Foreign Bodies in the Foot
Splinters, glass, needles, and other retained foreign bodies cause persistent pain, infection, and granuloma formation. Dr. O'Carroll provides image-guided removal.
Toe & Forefoot
Great Toe Arthritis (Hallux Rigidus)
Stiff, painful big-toe arthritis is one of the most common forefoot complaints in adults. Dr. O'Carroll offers conservative, joint-preserving, and fusion options.
Toe & Forefoot
Hammertoes & Toe Deformities
Hammertoes, claw toes, and mallet toes start flexible and become rigid. Treated early they're manageable conservatively; treated late they require reconstruction.
Toe & Forefoot
Ingrown Toenails
A common, painful, and very treatable problem. Dr. O'Carroll offers definitive in-office care for recurrent ingrown toenails.
Toe & Forefoot
Metatarsal Fractures
From simple stress fractures to displaced Jones fractures, metatarsal injuries demand accurate diagnosis to prevent nonunion or chronic pain.
Toe & Forefoot
Morton's Neuroma
A Morton's neuroma is a thickening of nerve tissue between the metatarsal heads - most often the third interspace. Diagnosed accurately, it's very treatable.
Toe & Forefoot
Plantar Warts
Plantar warts are caused by HPV and can be stubbornly resistant to treatment. Dr. O'Carroll offers a stepwise approach that reliably clears even chronic warts.
Toe & Forefoot
Soft Tissue Masses
Most foot lumps are benign - but every new mass deserves an accurate diagnosis. Dr. O'Carroll evaluates and treats lipomas, fibromas, ganglia, and other soft-tissue lesions.
