Distal humerus fractures require stable fixation and early joint motion, similar to other intra-articular fractures, but are difficult to treat adequately because of the anatomical complexity, severe comminution, and accompanying osteoporosis. In most cases, surgical treatment is performed using two supporting plates. Plate fixation can be divided into right angle plate fixation and parallel plate fixation. In addition, depending on the type of fracture, surgical procedures can be performed differently, and autologous bone grafting can be required in the case of severe bone loss. The elbow joint is vulnerable to stiffness, so it is important to start joint movement early after surgery. Postoperative complications, such as nonunion, ulnar nerve compression, and heterotopic ossification, can occur. Therefore, accurate and rigid fixation and meticulous manipulation of soft tissues are required during surgery.
Heterotopic ossification around the patellar tendon is known to be extremely rare. A 42-year-old man had a transverse fracture of the left patella. Open reduction and tension band wiring were performed. At four weeks, plain radiographs showed an extensive ossification around the patellar tendon and the patient presented limitation of flexion and pain in kneeling position. We just encouraged active and passive ranges of motion exercises and performed one manipulation under anesthesia. At the final follow-up (10 months post-operatively), he was able to flex his knee by 140 degrees. We present a case of heterotopic ossification around the patellar tendon with limitation of knee flexion that was successfully treated with nonoperative treatment.
Rupture of sciatic nerve is a rare injury in minimally displaced pelvic bone fracture. We report one case of complete rupture of sciatic nerve that were resulted from the extremely protruded Kuncher nail inserted before accident and the preexisting heterotopic ossification with a review of the relevant literature.
