Imaging of patellar fractures
نویسندگان
چکیده
Patellar fractures account for approximately 1% of all skeletal fractures and may result from direct, indirect, or combined trauma. Because of the importance of patellar integrity for knee extension and the risk of associated injury to the extensor mechanism, accurate reporting and description of fracture type is paramount for appropriate management. This pictorial essay aims to review the normal anatomy of the patella, the mechanisms of injury and different types of patellar fractures, with a brief introduction to therapeutic management. Teaching Points • Patellar fractures are classified according to their morphology and degree of displacement.• Direct trauma results in stellate fractures.• Indirect trauma results in transverse fractures.• Displacement should raise suspicion for retinacular injury.

At the end of this article, the reader should be able to (1) recognise normal anatomy and anatomical variants of the extensor mechanism of the knee on various imaging modalities, including plain film, ultrasound and MRI; (2) diagnose a broad spectrum of EM injuries in adult and paediatric patients including patellar and quadriceps tendinopathy, Osgood-Schlatter disease, Sindig-Larsen-Johansson ...
متن کاملSleeve fracture of the adult patella
RATIONALE The patellar fractures are common in adults, but rare in children. As a particular type of patellar fracture, however, sleeve fractures are almost always limited to children in the under 16's group. PATIENT CONCERNS Herein, we report a rare case of a 19-year-old healthy adult female who presented sleeve fracture at the superior pole of the left patella. The clinical and radiological...

The authors did percutaneous, arthroscopic-assisted osteosynthesis of patellar fractures associated with skin abrasions and lacerations in 11 patients. Skin problems did not delay the operation and the rehabilitation. The average followup was 2.8 years. All fractures healed without complications and good results were obtained in all patients using the criteria of Levack et al. This technique av...

Osteochondral fracture of the patella following a lateral patellar dislocation can be treated with operative and nonoperative techniques that are dictated by the clinical presentation. In the presence of large fragments following acute fractures, arthroscopic retrieval and fixation are advocated, whereas smaller displaced fragments may be removed and discarded as loose bodies. Several methods o...
