Osteochondral Defects of the Talus: Current Management Dilemmas.

Osteochondral defects or lesions of the talus represent a management challenge. Arthroscopic débridement is the treatment of choice for patients with an osteochondral lesion of the talus in whom nonsurgical treatment fails. Although surgeons have a better understanding of the risk factors for failed débridement in patients with an osteochondral lesion of the talus, the treatment of patients in whom a high risk for failed débridement exists and patients in whom débridement fails is controversial. Surgeons should understand the current adjunct therapies available for the management of osteochondral lesions of the talus, including cartilage preparations, platelet-rich plasma, bone marrow aspirate, bone graft or bone graft substitutes, and whole bone cartilage transfer (osteochondral autograft transfer); however, evidence for the use of one adjunct therapy more than another is lacking.

Sural Versus Perforator Flaps for Distal Medial Leg Wounds.

Soft tissue coverage of distal medial ankle wounds is a challenging problem in orthopedic surgery because of the limited local tissues and prominent instrumentation. Traditionally, these wounds required free tissue transfer to achieve suitable coverage and subsequent bony union. To better respect the reconstructive ladder and to avoid the inherent difficulty of free flap coverage, rotational flaps have been used to cover these wounds. Both sural fasciocutaneous flaps and rotational fasciocutaneous perforator (propeller) flaps have been described for distal medial soft tissue coverage. The authors performed a retrospective chart review of patients who underwent distal medial leg coverage with the use of either sural flaps or rotational fasciocutaneous perforator flaps. The authors identified 14 patients by Current Procedural Terminology code who met the study criteria. The average age and degree of medical comorbidities were comparable in the 2 groups. The authors reviewed their medical records to evaluate fracture healing, flap size, complications, and return to normal shoe wear. All 7 sural flaps healed without incident, with underlying fracture healing. Of the 7 perforator flaps, 6 healed without incident, with underlying fracture healing. One perforator-based flap was complicated by superficial tip necrosis and went on to heal with local wound care. All patients returned to normal shoe wear. Both sural artery rotational flaps and posterior tibial artery-based rotational flaps are viable options for coverage of the distal medial leg. Coverage can be achieved reliably without microsurgery, anticoagulation, or monitoring in the intensive care unit.
