Arthrography of the ankle joint in chronic instability

Papers on arthrography of injuries of the lateral ligaments of the ankle relate mainly to recent distortion of the joint. Arthrography performed at a later stage after injury generally is considered useless. In fact, changes in chronic instability are observed; they are subtle and consist either of small recesses adjacent to the lateral malleolus or communication of the joint with the peroneal tendon sheaths. Arthrography was assessed in 61 cases of recurrent lateral sprains of the ankle more than 2 weeks after acute injury; 38 were considered as positive. Twenty-five patients had operative evaluation, with four false negative and one false positive results. Small recesses adjacent to the lateral malleolus or opacification of the peroneal tendon sheaths are sequelae of an acute sprain with tear of the anterior talofibular and/or the calcaneofibular ligaments. Although false negative results occur, arthrography is useful in the preoperative assessment of chronic ankle instability.     

Impingement syndromes of the ankle

Ankle impingement syndromes are categorised according to their anatomical site around the tibiotalar joint. Anterolateral, anterior and posterior ankle impingement has been extensively described in the orthopaedic and radiology literature with more recent studies describing posteromedial and anteromedial impingement. This article aims to demonstrate the potential spectrum of imaging findings for each ankle impingement syndrome as well as the relative contributions of ultrasound and MR imaging for diagnosis and image-guided treatment.     

Ankle MRI for anterolateral soft tissue impingement: increased accuracy with the use of contrast-enhanced fat-suppressed 3D-FSPGR MRI

OBJECTIVE: To validate the use of contrast-enhanced (CE) fat-suppressed three-dimensional (3D) fast gradient-recalled acquisition in the steady state with radiofrequency spoiling (FSPGR) magnetic resonance imaging (MRI) for the diagnosis of anterolateral soft tissue impingement of the ankle, as compared to the use of routine ankle MRI. MATERIALS AND METHODS: Contrast-enhanced fat-suppressed 3D-FSPGR MRI and routine MRI scans were retrospectively reviewed for 45 patients with arthroscopically proven anterolateral impingement. In addition, scans were reviewed in 45 control subjects with diagnoses other than impingement. Two radiologists independently reviewed the two sets of images in random order. Using areas (Az) under the receiver operating characteristic curve (ROC), we compared the depiction of anterolateral soft tissue impingement in the two sets of images. RESULTS: The overall accuracy for lesion characterization was significantly higher (p < 0.05) using the CE fat-suppressed 3D-FSPGR MR images (Az = 0.892 and 0.881 for reader 1 and 2, respectively) than using the routine MR images (Az = 0.763 and 0.745). The use of CE fat-suppressed 3D-FSPGR MRI enhanced impingement depiction in most cases. However, in cases with a thickened non-enhancing scar or joint effusion, the routine images better depicted a soft tissue mass that intruded into anterolateral gutter than the CE images. CONCLUSION: The use of CE fat-suppressed 3D-FSPGR MRI of the ankle allows a more accurate assessment of anterolateral soft tissue impingement of the ankle, as compared to the use of routine MRI.

Arthroscopic assisted reduction and fixation of a juvenile Tillaux fracture

We report a case of Tillaux fracture of the distal tibia in a 14-year-old patient. Reduction and fixation of the fracture was achieved arthroscopically through the anterolateral portal. The patient was able to participate in competitive athletic activities 3.5 months after surgery with an AOFAS score of 100. Arthroscopy is an expedient tool in the management of intra-articular fractures of the ankle providing anatomical reduction under direct visualization with minimum intervention.

The fibrocartilaginous sesamoid: a cause of size and signal variation in the normal distal posterior tibial tendon

The aim of this study was to investigate the presence of fibrocartilage within the distal posterior tibial tendon (PTT) before its division correlating with size and signal variation on MR images through a radio-anatomic and pathologic study. Eight fresh cadaveric feet underwent MR imaging were cut into 4-mm slices in the axial plane. The PTT specimens were harvested at the tendon distal portion before its division and sent to pathology. Thirty-three asymptomatic subjects underwent axial double-echo turbo-spin-echo MR imaging. Proximal and distal PTT signal and diameter were evaluated. In cadavers, every PTT flared distally. Intratendinous fibrocartilage and ossified sesamoid were found in, respectively, 87.5 and 12.5% of the cases. Distal PTT flaring was demonstrated in 100% of the asymptomatic subjects (mean diameter 8 mm). An intratendinous high signal intensity on proton-density-weighted images and sesamoid bone were evidenced in, respectively, 36 and 33% of the cases. Proximally, PTT presented a 4-mm mean diameter and was hypointense in 100% of the cases. Only one accessory navicular bone was detected. Laterally off-centered increased intratendinous signal intensity as well as PTT distal widening with otherwise normal MR imaging features are related to an intratendinous fibrocartilage.

踝关节本体感受器损伤与慢性踝关节不稳定关系的初步研究

Objective To analyze the effect of ankle joint proprioceptor injury on the functional ankle instability. Methods The study enrolled 18 ( 13 males) with chronic ankle instability treated with ligament reconstruction operation. The American Orthopaedic Foot and Ankle Surgeons (AOFAS)score was used for evaluation of the function before and after operation and the balance system evaluate the proprioception function. The two ankle ligament specimens from fresh frozen body and the tissue samples from operation were used for investigation of the structure and distribution of the sensory corpuscles by using histology and immunohistoehemical staining. Results The sections were evaluated with a microscope and an image analyzer. Labeled nerve endings were mapped, measured and categorized. Type Ⅰ ( Ruffini-like ending) , type Ⅱ ( Pacinin-like corpuscle ) and type Ⅳ- (noncorpuscular) nerve endings could be identified in all the lateral ankle ligaments, with majority of types Ⅰ and Ⅱ nerve endings.These receptors were distributed primarily over the superficial ligament and near the bony attachments.There was statistical difference between preoperative and postoperative sway distance as well as between preoperative and postoperative AOFAS score. Conclusions This study suggests that the longer history,severer symptoms and lower AOFAS score may lead to the severer injury of the mechanical proprioceptors.The proprioceptor injury is correlated with ankle joint instability and the ligament reconstruction is effective to avoid the repeated injury of the proprioceptor.
