This condition usually presents with erythema, edema, a crusted drainage, and pain along the affected nail border. Usually the etiology involves trauma, a diseased nail, ill-fitting footgear, or injudicious cutting of the nail.

Treatment
A digital block is obtained with 3 to 5cc of 1% lidocaine and a 25 or 27 gauge 1 1/4 inch needle at the proximal portion of the toe making sure to address all four nerves (dorsomedial, plantar medial, dorso-lateral, and plantar-lateral). Once anesthesia is achieved, prep the toe with betadine and remove approximately 1/8th of the offending nail border. Using a thin instrument, slide under the offending nail border from distal to proximal. With the same instrument detach the dorsal part of the nail from the proximal toe tissue fold. With iris scissors, cut the detached 1/8th of the nail boarder from distal to proximal making sure to cut the nail under the proximal toe tissue fold, then roll the detached nail out with a hemostat.

Have the patient soak in warm water twice a day for 1 or 2 days. Post nail removal pain relief can be achieved with NSAIDs. The patient may need a day or two of no marching. If an ingrown toenail is a chronic problem (three or more removals from the same side) the patient may be referred to podiatry for permanent removal. The majority of patients will not need antibiotics. This condition may be perceived as a foreign body reaction. When the foreign body (the nail) is removed the problem is solved.

Corns and Calluses

Corns and calluses are specific accumulations of stratum corneum over bony prominences. Corns most often occur on the dorsal aspect of hammer toes. Calluses usually appear plantar near the metatarsal heads. Corns and callus are the reaction of normal skin to an abnormal amount of intermittent friction and pressure. They can be quite tender and can interfere with work as well as off duty activity. Calluses are often misdiagnosed as planter warts. Plantar warts have pinpoint spots of punctate bleeding on debridement while calluses are free of bleeding during debridement.

Treatment
The treatment for corns and calluses are focused at decreasing the skin build up and reducing the friction and pressure from the affected area(s). Debride the excess skin with a 10 or 15 blade. Corns are best treated after debridement with a larger, wider shoe and a moleskin appeture pad with a cut out area over the lesion. A callus is treated with debridement along with the placement of a Spenco® insole into the work shoe. Spenco® insoles are carried by most military exchanges.

Discourage the use of medicated pads or liquid corn removers since these treatments can cause ulceration. A routine consult to podiatry is appropriate when the patient is on shore duty and wishes more aggressive treatment.

Plantar Foot Laceration

Treatment
Flush the wound with 1% lidocaine containing 1:100,000 epinephrine. Inspect the wound for any foreign bodies. Copiously flush the wound with sterile water from a 10 cc syringe until all debris is washed or picked out. If the wound is clean and 6 hours old or less, anesthetize the area and close with 3-0 or 4-0 nylon sutures. If the wound is old or dirty lightly pack it open with moist Nu-gauze. Dress the wound with nonadherent gauze, gauze fluff, and roller gauze (kling). Keep patient's foot elevated for 2 days and keep patient non-weight bearing on crutches for 2 weeks. If the wound is healed, sutures can be removed after 2 weeks. Unremovable foreign bodies in the foot should be referred to podiatry.

Heel Spur Syndrome and Plantar Fasciitis

Heel spur syndrome and planter fasciitis are similar conditions on the plantar aspect of the foot. Both conditions involve the structure known as the planter fascia. Heel spur syndrome presents with pain on the plantar medial side of the heel and is usually presents as pain during the "first step in the morning." Plantar Fasciitis can present as tenderness throughout the arch with pain also experienced as the "first step in the morning". However, pain is experienced usually later in the day during exercising or other daily activities. Both heel spur syndrome and plantar fasciitis are overuse-related conditions. These can be secondary to foot type, life style (Marine) or overweight body habitus.

Treatment
Have the patient buy an over the counter arch support such as the Spenco -Walker Runner® or Sorbathain® arch support. Medications should include NSAIDs. Educate the patient in stretching the plantar facie twice a day by dorsiflexing the foot, dorsiflexing their toes, and massaging the planter fascia with their other hand. The patient may also massage the planter fascia with ice. Place the patient on about 30 days light duty. If pain persists for more than one month inject the point of max tenderness with a 1:1:1 mix of 1% lidocaine without epinephrine + 0.5% marcaine without epinephrine + kenalog 10, 3cc total. If pain continues for more than 2 months referral to podiatry or physical therapy is recommended.
