Polyarteritis nodosa is a progressive, often life-threatening, vasculitis affecting multiple organs, including the skin and peripheral nerves. We report a patient presenting with systemic features of the disease and with characteristic lesions in the feet 3 weeks after vaccination against hepatitis B virus infection.
Pure open dislocation of the ankle, or dislocation not accompanied by rupture of the tibiofibular syndesmosis ligaments or fractures of the malleoli or of the posterior border of the tibia, is an extremely rare injury. A 62-year-old man injured his right ankle in a motor vehicle accident. Besides posterolateral ankle dislocation, there was a 7-cm transverse skin cut on the medial malleolus, and the distal end of the tibia was exposed. After reduction, we made a 2- to 2.5-cm longitudinal incision on the lateral malleolus; the distal fibular fracture was exposed. Two Kirschner wires were placed intramedullary in a retrograde manner, and the fracture was stabilized. The deltoid ligament and the medial capsule were repaired. The tibiofibular syndesmosis ligaments were intact. At the end of postoperative year 1, right ankle joint range of motion had a limit of approximately 5° in dorsiflexion, 10° in plantarflexion, 5° in inversion, and 0° in eversion. The joint appeared normal on radiographs, with no signs of osteoarthritis or calcification. The best result can be obtained with early reduction, debridement, medial capsule and deltoid ligament restoration, and early rehabilitation. Clinical and radiographic features at long-term follow-up also confirm good mobility of the ankle without degenerative change or mechanical instability. (J Am Podiatr Med Assoc 98(6): 469–472, 2008)
We describe a 70-year-old nonimmunocompromised woman with spontaneous bilateral ankle and midfoot sepsis and a deep-space abscess of the right lower leg. Salvage of both limbs was achieved by aggressive bilateral soft-tissue and osseous debridement, including a four-compartment fasciotomy of the right lower leg, antibiotic-loaded polymethyl methacrylate bone cement implantation, delayed allogeneic bone grafting of the osseous defects impregnated with autologous platelet-rich plasma bilaterally, and external fixation immobilization, implantable bone growth stimulation, and split-thickness skin graft coverage of the right lower leg, ankle, and foot. Osseous incorporation of the bone grafts bilaterally occurred 8 weeks after surgery. No soft-tissue or osseous complications occurred during the postoperative period or at 18-month follow-up except for arthrofibrosis in the right ankle; there was no evidence of recurrent abscesses, sequestrum, or wound-related problems. A review of the literature regarding bilateral pedal sepsis and the techniques used for limb salvage in this patient are presented in detail. (J Am Podiatr Med Assoc 96(2): 139–147, 2006)
