1/42. Fracture of the anterior nasal spine.

    A case of sports-related fracture of the anterior nasal spine in a 18-year-old male is presented. This is actually the third case reported in the literature, and the first in which a combined fracture of the nasal septum is described. A group of signs and symptoms was proposed as the main clinical features of this situation. Fracture of the anterior nasal spine should be considered in the differential diagnosis of injuries involving the midface. ( info)

2/42. rupture of the quadriceps tendon after arthroscopic lateral meniscectomy: A postoperative complication?

    We report a case of complete quadriceps tendon rupture that occurred a few days after arthroscopic lateral meniscectomy. Complications following arthroscopy are rare; there have been many reports of quadriceps tendon rupture in the literature, but none by this kind of mechanism. ( info)

3/42. Traumatic avulsion of the trachea associated with cricoid fracture.

    A 15-year-old girl sustained a cricoid fracture, avulsion of the trachea, and bilateral cord paralysis in a automobile injury. An airway was established by intubation, and primary repair was performed on the day of injury. A postoperative stricture was successfully managed by endoscopic dilatation and injection of triamcinolone into the stricture. Function of one vocal cord appears to be returning 6 months after the injury, and the patient is leading an active life. ( info)

4/42. Fracture of the laryngeal cartilage. An incidental finding on bone scintigraphy.

    A patient complaining of headaches and bone pain at multiple sites had Tc-99m MDP scintigraphy performed for possible bone trauma after a motor vehicle accident. Bone imaging revealed a small focal increase in tracer uptake in the area of the laryngeal cartilage. There was some reluctance to place a label on this abnormality because the findings were so unusual. The initial diagnosis was a probable fracture of the laryngeal cartilage. Computed tomography of the neck also demonstrated a fracture but correctly localized it to the thyroid cartilage. ( info)

5/42. Efficacy of resorbable plates for reduction and stabilization of laryngeal fractures.

    We evaluated the efficacy of resorbable reconstruction plates (polylactic acid copolymer) for the open reduction and stabilization of displaced laryngeal fractures. Both MacroPore and Leibinger reconstruction plates were used with equal ease of application in 3 adult male patients. We found the plating system to be especially effective for the reduction of comminuted cricoid fractures. Adequate skeletal stabilization allowed early resumption of phonatory and respiratory function without long-term intraluminal stenting for skeletal support. No complications of hematoma, seroma, or infection were experienced. Resorbable plates appear to be relatively safe and useful for internal fixation of both cartilaginous and ossified parts of the larynx, allowing rapid rehabilitation and return of function. ( info)

6/42. Sleeve fracture of the patella in a child.

    Sleeve fracture of the inferior pole of the patella is a rare and distinctive fracture in children with few published reports. These fractures are frequently misdiagnosed and neglected. We highlight a case of a neglected and misdiagnosed sleeve fracture of the patella in an eleven-year-old boy. This was initially diagnosed as an avulsion fracture of the tibial tubercle. A good outcome was achieved after open reduction and internal fixation. ( info)

7/42. Laryngohyoid fractures after agonal falls: not always a certain sign of strangulation.

    Haemorrhagic fractures of the thyroid cartilage and hyoid bone are frequently observed in cases of strangulation and often regarded as evidence for an assault against the neck. In contrast, two cases of laryngohyoid fractures after agonal falls in prone position are presented to draw attention to alternative causes of these injuries with special regard to practical medicolegal casework. A 45-year-old man collapsed at a fairground and died after unsuccessful resuscitation. He showed excoriations at his elbows and right knee, a crush injury at the mentum and his mandibular front teeth were knocked out. The upper parts of the chest and the head showed blue discolouration as a marked sign of congestion due to heart failure. The right coronary artery (RCA) was completely obturated by a 5 cm long post-stenotic thrombus with subsequent myocardial infarction of the lateral part of the left ventricle. Both superior horns of the thyroid cartilage were fractured with surrounding haemorrhage, the skin and muscles of the neck uninjured. In the second case, a 63-year-old woman with a mobility handicap had fallen from a 2m high lifting platform and was found in prone position with her wheelchair on her. resuscitation efforts were not successful. autopsy showed signs of blunt external force against head, neck, chest and limbs. Examination of the neck revealed haemorrhage of the right sternocleidomastoid muscle, both superior horns of the thyroid cartilage were fractured, as well as the hyoid bone, with slight haemorrhage of the surrounding soft tissue and mucosa. On the same level, the fifth intervertebral disk was ruptured, without any injury of the spinal cord. These cases demonstrate that laryngohyoid fractures should not be overestimated as unequivocal indication of neck compression and may well be caused by falls, even at ground level. ( info)

8/42. Fixation of a talar osteochondral fracture with cyanoacrylate glue.

    Cyanoacrylate glue was invented by Ardis in 1949 and was first used in surgery in 1959 by Coover. By further modifications, a nonhistotoxic form, butyl-2-cyanoacrylate, which had strong tissue binding properties even in nondry environments, was developed. Its use in the fixation of fractures and osteotomies is still under investigation and has had promising results in treatment of craniofacial and mandibular injuries. We fixed a talar osteochondral fracture with cyanoacrylate. After 3 months, magnetic resonance imaging showed an anatomically reduced and intact chondral surface. The clinical result was excellent. We believe cyanoacrylate glue may form an alternative means of fixation for osteochondral and, possibly, for chondral fractures. ( info)

9/42. Traumatic articular-bursal fistula in a collegiate football player.

    A collegiate football player suffered a direct blow to the distal quadriceps mechanism, resulting in a partial tear of the vastus medialis obliquus. Over time, he began to develop activity-related swelling of his prepatellar bursa. By 6 weeks after his injury, an area of swelling the size of a golf ball would rapidly develop with just 5 minutes of quadriceps exercises. Swelling would diminish within a few hours of rest. A magnetic resonance imaging examination suggested a fistula track from the articular space through the vastus medialis obliquus into the prepatellar bursal area. When prolonged rest did not improve his symptoms, he was taken to surgery. Arthroscopic visualization confirmed a traumatic fistula between the articular space and the prepatellar bursa, allowing free egress of fluid. A spinal needle was used to localize the fistula tract to allow this to be identified for an open, layered suture closure. An area of traumatic chondrosis on the medial side of the patella with loose chondral flaps was also debrided as the probable "fluid generator." The patient enjoyed a full recovery and was back to playing college football 10 weeks after surgery. ( info)

10/42. Extensor mechanism disruption after contralateral middle third patellar tendon harvest for anterior cruciate ligament revision reconstruction.

    The contralateral central third patellar tendon autograft is a reliable graft choice for revision, and recently, for primary reconstruction of the anterior cruciate ligament (ACL). We report 2 complications including a lateral third tibial tuberosity fracture and a distal patellar tendon avulsion with contralateral patellar tendon autograft with disruption of the extensor mechanism of the donor knee. A patient sustained a lateral tibial tuberosity fracture of the donor knee and underwent open reduction and internal fixation. At 1-year follow-up, she had no extensor lag and full range of motion. Another patient sustained a distal patellar tendon avulsion of the donor knee and underwent primary repair. Three years postoperatively, she had a full range of motion and no extensor lag. Although contralateral middle third patellar tendon autograft for primary and revision ACL reconstruction is established in the literature, extensor mechanism complications can occur. Technical considerations are important to avoid weakening the remaining patellar tendon insertion. Postoperative nerve blocks or local anesthetics may alter pain feedback for regulation of weight bearing and contribute to overload of the donor knee. ( info)
