Osteochondritis dessicans of the ankle is a situation often encountered by the foot and ankle physician. Many remedies have been described within the literature together with solid immobilization, arthroscopic debridement, open debridement, and autogenous grafting (https://travisejib40517.blogsidea.com). The NEXA OsteoCure™ bone graft plug permits for speedy lesion excision while avoiding the morbidity related to obtaining an autograft. The authors provide a brief evaluate of talar dome lesions including staging and classification and their experience and approach involved for utilizing NEXA Orthopedics OsteoCure™ bone graft plugs.

Osteochondral defects of the talar dome, aka osteochondritis dissecans, are frequent pathological entities encountered by the podiatric physician. Although trauma is thought to play a major role in the genesis of those lesions, idiopathic osteonecrosis might even be a trigger. Subjectively, these patients often current complaining of a deep, aching, non-descript pain in the ankle joint that worsens with activity.

Clinical examination may reveal joint line tenderness, effusion, in addition to pain upon ankle joint vary of movement. Diagnosis is continuously made with imaging after high clinical suspicion, and the lesions are sometimes seen anterolaterally or posteromedially. Figure 1 Diagnosis of osteochondral defects are sometimes made with CT scans. The lesions are typcially seen anterolaterally and posteromedially. Insight into the morphology and mechanism of action of those lesions was illustrated in a retrospective examine of thirty-one ankles in twenty-9 patients with osteochondral lesions by Canale, et al. It was discovered that lateral lesions were associated with inversion or inversion-dorsiflexion trauma and that these lesions are morphologically shallow and anteriorly situated on the talar dome. Lateral lesions were more likely to develop into displaced within the joint and to have persistent symptoms. Medial lesions had been both traumatic and atraumatic in origin, morphologically deep, situated extra posteriorly on the talar dome, and less symptomatic. These typically occurred with a plantarflexion and inversion sort of harm.

With an acute damage, the osteochondral lesion may not be visible on the preliminary radiographs. If there is a excessive index of suspicion, repeat radiographs in two to four weeks must be obtained or one should consider more advanced imaging. In a study by Anderson, et al., it was found that when plain radiographs of the ankle are relied on for the prognosis of an osteochondral fracture of the talus, many lesions remain undiagnosed. Stage-I osteochondral fractures present no diagnostic changes on plain radiographs, and Stage-II lesions are often subtle and, subsequently, are sometimes overlooked by both radiologists and clinicians. The mostly used classification system for these injuries was created by Berndt and Harty. A type I lesion represents a small area of compression. A type II lesion is a partially detached osteochondral lesion. When the lesion becomes fully detached, but stays in its anatomical location, it is a type III lesion. A detached lesion with any movement or migration is classified as type IV.

A CT might provide more correct staging of the lesion, although classification may not correlate with intraoperative findings. Figure 2 The CT might supply extra accurate staging of the lesion, although classification could not correlate with intraoperative findings. Pettine, et al., evaluated seventy-one osteochondral fractures of the talus for a mean of 7.5 years after the onset of symptoms to find out which factors influenced the final consequence. It was discovered that the kind of fracture was the most important issue and that delay in therapy additionally affected the outcomes adversely. In the research by Canale, et al., using the classification system of Berndt and Harty, it appeared that Stage-I and Stage-II lesions ought to be treated non-operatively, no matter location. Stage-III medial lesions ought to be handled non-operatively initially but if signs persist, surgical excision and curettage are indicated. Stage-III lateral lesions and all Stage-IV lesions needs to be handled surgically and early. Long-term outcomes indicated that few lesions unite when treated non-operatively. Degenerative modifications in the ankle joint, whether symptomatic or not, were frequent regardless of the type of treatment.

Non-operative therapy of these lesions consists of casting and immobilization. There is no such thing as a proof, nevertheless, that these patients have to be immobilized if they're kept non-weight bearing. There can also be no proof that a non-weight bearing solid gives better results than a weight bearing solid. A retrospective research of 22 ankles in 22 patients with osteochondral talar dome lesions between 1975 and 1983 indicated that surgical remedy yields superior results to conservative therapy. Many of these lesions are treated surgically with arthroscopic joint examination and debridement of the lesion. This course of may be aided by an exterior joint distracting device. Anterolateral lesions are usually more amenable to arthroscopic debridement than posteromedial lesions due to their anatomical location. In a examine by Kumai, et al., the authors found good clinical ends in arthroscopic debridement and k-wire drilling of lesions in patients who have been younger than sixty years previous.6 Posteromedial lesions sometimes necessitate an osteotomy of the medial malleolus for publicity, with open discount and inner fixation and subsequent prolonged non weight-bearing.
