“…It is known that lowering the photon energy can be used to clarify details of soft tissues. The results are essentially similar to increasing contrast in the evaluation of a digital radiograph, which has been used in the past to assess patients with Achilles tendon problems (Fischer 1974a,b, Scotti et al 1979). …”

Background and purposeA retrocalcaneal bursitis is caused by repetitive impingement of the bursa between the Achilles tendon and the posterosuperior calcaneus. The bursa is situated in the posteroinferior corner of Kager's triangle (retrocalcaneal recess), which is a radiolucency with sharp borders on the lateral radiograph of the ankle. If there is inflammation, the fluid-filled bursa is less radiolucent, making it difficult to delineate the retrocalcaneal recess. We assessed whether the radiographic appearance of the retrocalcaneal recess on plain digital (filmless) radiographs could be used in the diagnosis of a retrocalcaneal bursitis.MethodsWhether or not there was obliteration of the retrocalcaneal recess (yes/no) on 74 digital weight-bearing lateral radiographs of the ankle was independently assessed by 2 observers. The radiographs were from 24 patients (25 heels) with retrocalcaneal bursitis (confirmed on endoscopic calcaneoplasty); the control group consisted of 50 patients (59 heels).ResultsThe sensitivity of the test was 83% for observer 1 and 79% for observer 2. Specificity was 100% and 98%, respectively. The kappa value of the interobserver reliability test was 0.86. For observer 1, intraobserver reliability was 0.96 and for observer 2 it was 0.92.InterpretationOn digital weight-bearing lateral radiographs of a retrocalcaneal bursitis, the retrocalcaneal recess has a typical appearance.

“…Of the 40 studies included, 25 studies reported on OSD‐related imaging findings 4‐7,9,11‐30 . Most studies used radiography (n = 10) or US (n = 6), with the remaining studies using radiography and US (n = 4), radiography and MRI (n = 3), MRI only (n = 1) and one study using both CT, MRI, radiography, and bone scintigraphy (n = 1).…”

This systematic review aimed to describe the imaging characteristics of Osgood‐Schlatter (OSD) compared with controls and imaging findings over time. A systematic search was conducted in Embase, CINAHL, and PubMed from inception until July 2021. Forty studies were eligible and included based on inclusion criteria on OSD diagnosis, the number of patients, and imaging outcomes. In patients with OSD, but not controls, findings were soft‐tissue swelling of the cartilage and infrapatellar bursa, tendon changes, increased Doppler flow, and fragmentation of the secondary ossification center. Follow‐up studies reported improvements over time, but some identified persistent tendon thickening and/or ossicles. Adults with OSD generally present with free ossicles. Findings were inconsistent on whether different morphometric features were altered in OSD compared to controls. OSD patients were classified within the early stages of tibial tuberosity maturation. This review documents that OSD presents with tissue alterations that do not appear in controls or the patient's asymptomatic knee. Notably, a large portion had tendon involvement, and ossicles seem to be associated with residual symptoms after maturation. Standard imaging of adolescents with OSD needs to be carefully considered when determining if tissue alterations are related to disease progression or part of the normal maturation.

“…Some believe the cause to be trauma to the patellar tendon at its insertion to the tibial tubercle (Fig 26) (29,30). Osgood-Schlatter disease is typically seen in active adolescents, particularly those who participate in sports that require jumping, squatting, and kicking, and can be bilateral in up to 50% of patients (30,31).…”

“…When used, radiography shows fragmentation of the tibial tubercle, although this finding alone may represent a normal ossification center. Therefore, the most important diagnostic criteria are seen at MR imaging and include (a) soft-tissue swelling anterior to the tibial tuberosity, (b) loss of the sharp inferior angle of the infrapatellar fat pad and surrounding soft tissues, (c) thickening and edema of the inferior patellar tendon, and (d) infrapatellar bursitis (5,29,31). On occasion, the disease along with associated radiographic findings persist into adulthood.…”

Avulsion injuries are common among participants in organized sports, especially among adolescent participants. Imaging features of both acute and chronic avulsion injuries of the pelvis, knee, ankle and foot, shoulder, and elbow were evaluated to help distinguish these injuries from more serious disease processes such as neoplasm and infection. At radiography, acute injuries (ie, those resulting from extreme, unbalanced, often eccentric muscular contractions) may be associated with avulsed bone fragments, whereas subacute injuries have an aggressive appearance that may include areas of mixed lysis and sclerosis. Chronic injuries (ie, those resulting from repetitive microtrauma or overuse) or old inactive injuries may be associated with a protuberant mass of bone and may bear a striking resemblance to a neoplastic or infectious process. Although not usually required, computed tomography is helpful in the diagnosis if radiographic findings are equivocal or if the injury is not in the acute phase. MR imaging is best suited for the evaluation of injuries to muscles, tendons, and ligaments. Recognition of characteristic imaging features and familiarity with musculotendinous anatomy will aid in accurate diagnosis of avulsion injuries.
