Purpose:
The purpose of this study was to assess a series of lateral inverted osteochondral fractures of the talus.
Methods:
Over a 17-year period, 10 patients with an acute lateral inverted osteochondral fracture of the talus after an inversion injury to the ankle were identified. Diagnosis was made by physical examination, radiographs, magnetic resonance imaging, and/or computed tomography scan. Arthroscopy was initially performed on all patients. All patients had an inverted osteochondral fragment. In 8 of 10 patients the fragment was reattached in an open manner in conjunction with lateral ligament reefing. The fragment was excised in 2 patients. The mean age of the patients was 17.2 years. They were evaluated with the Single Assessment Numeric Evaluation, American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale, modified Weber score, Berndt and Harty score, and Short Form 36 version 2 score. Physical and radiographic examination was also performed. The mean time to follow-up was 112.3 months (9.3 years).
Results:
The mean American Orthopaedic Foot and Ankle Society score improved from 18.9 preoperatively to 86.9 postoperatively (P ≤ .0001). The mean Single Assessment Numeric Evaluation and modified Weber scores were 81.6 and 81.5, respectively. On the Berndt and Harty scale, 6 patients had a good to excellent rating; 3, fair; and 1, poor. The mean Short Form 36 version 2 scores corresponded to national averages for healthy populations. Mean loss of motion for dorsiflexion and plantarflexion was 6.8° and 3.0°, respectively, when compared with the contralateral side. All patients showed some osteophyte formation on follow-up radiographs.
Conclusions:
An inverted osteochondral fracture of the lateral talus (lateral, inverted, fracture, talus [LIFT lesion]) can occur after a twisting injury to the ankle. Clinical suspicion should be high, especially in the younger athlete. This injury can be successfully managed with a combined arthroscopic and open approach.
Level Of Evidence:
Level IV, therapeutic case series.

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
