11/155. Resection of a plantar calcaneal spur using the holmium:yttrium-aluminum-garnet (Ho:YAG) laser.

    Many procedures have been described for the resection of plantar calcaneal spurs as treatment of heel spur syndrome and chronic plantar fasciitis. Most of these techniques involve a medial incision of between 2 and 6 cm for adequate exposure of the calcaneal spur. This article describes a new technique for resecting a calcaneal spur with a smaller medial incision using the holmium:yttrium-aluminum-garnet (Ho:YAG) laser. This laser permits adequate resection of a plantar calcaneal spur as well as coagulation of the bone and surrounding tissues. This minimally invasive procedure has been used with good results over the past year by the senior author (W.K.S.) for the resection of calcaneal spurs. ( info)

12/155. Pseudo-aneurysm of the popliteal artery by femoral exostosis in a young child.

    Exostosis is a solitary benign bone tumor frequently observed in children. It may be totally quiescent or provoke complications. We report a case of pseudo-aneurysm of the popliteal artery caused by an exostosis on the lower metaphysis of the femur in a 12-year-old boy. This unusual complication mostly reported in young males (mean age 19 years) occurs in the context of an initial trauma in half the cases. Surgical treatment is a semi-emergency requiring both bone and arterial repair. Preventive surgery should be discussed for all cases of exostosis with a risk of arterial damage due to the gravity of the potential vascular complications. ( info)

13/155. Avulsion fractures of the anterior inferior iliac spine: the case for surgical intervention.

    Two cases of avulsion fracture of the anterior inferior iliac spine are reported. One was a missed diagnosis that resulted in exostosis formation needing excision. The second case was an adolescent with significant displacement of the fragment and a primary open reduction and internal fixation was done. A high index of suspicion is necessary to diagnose this relatively rare injury and surgery has a role in carefully selected cases. ( info)

14/155. Ridge augmentation using mandibular tori.

    A 19-year-old female was referred by her dental practitioner for the restoration of missing maxillary lateral incisors and canines. Ridge augmentation was required. This was undertaken using mandibular tori as the sites for harvesting bone. The grafting was successful and the spaces were subsequently restored using resin-bonded bridgework. The case reports that mandibular tori provide a local and convenient source of bone for ridge augmentation procedures. ( info)

15/155. Solitary nodule of the great toe.

    We describe a 21-year-old woman with a subungual exostosis exhibiting both skin and nail findings. The patient presented with a firm, flesh-colored, nontender, subungual nodule in the distal nail bed of the great toe. Radiographic examination revealed focal calcification of the nodule, with direct communication to the underlying phalanx. Subungual exostosis should be considered in the differential diagnosis of any digital mass. Surgical excision, followed by curettage of the base, is the treatment of choice. ( info)

16/155. An unusual exostosis presenting as a bunion deformity.

    A large exostosis was the source of a bunion deformity in a 60-year-old woman. Its unusual clinical and radiographic features were suggestive of a bizarre parosteal osteochondromatous proliferation. However, histologic features were most consistent with a benign osteocartilaginous exostosis. ( info)

17/155. Symptomatic bursa formation with osteochondromas.

    Two cases of bursa formation in association with osteochondromas are presented. This condition may be confused radiographically and clinically with malignant transformation of the cartilage cap. Ultrasound examination on one of the patients proved helpful in arriving at the correct preoperative diagnosis. ultrasonography was also helpful to the surgeon with regard to size and extent of the bursa.

18/155. Symptomatic spur formation of bilateral proximal tibiofibular joints.

    Excessive, repetitive mechanical stress of the proximal tibiofibular articulation during sports activity can lead to degenerative changes and a syndesmotic joint. ( info)

19/155. Subungual exostosis of the third toe.

    Subungual exostosis is a variant of osteochondroma that appears as a pinkish nodule under the free end of the nail plate. It becomes symptomatic when large enough to disrupt the overlying nail on the digit or through mechanical irritation of the exostosis from physical activity. Appropriate workup of such a lesion is important, because many cases of subungual exostosis are initially misdiagnosed by a variety of specialists, including dermatologists. With the use of history and roentgenography, subungual exostosis can be effectively diagnosed or excluded. Appropriate treatment of subungual exostosis can be selected- surgical excision of the lesion with significant cure rates achieved. Although most cases of subungual exostosis are localized to the great toe, we describe a 32-year-old woman who developed a subungual exostosis on her right third toe. Appropriate diagnostic workup and surgical treatment of the right third-toe exostosis has resulted in complete relief of symptoms with no signs of recurrence 7 months after surgery. ( info)

20/155. popliteal artery thrombosis secondary to exostosis of the tibia.

    This report describes an exceptional case of popliteal artery thrombosis secondary to exostosis of the superior extremity of the superior tibia in a young adult. Correct diagnosis was made during re-operation for recurrent thrombosis. Surgical treatment consisted of resection of the bony tumor and venous bypass to reestablish arterial continuity. Femoropopliteal vascular complications of exostosis are rare, with most cases involving arterial aneurysms or false aneurysms. Differential diagnosis in our young patient took into account the other causes of popliteal thrombosis: entrapped popliteal artery, adventitious cyst, fibrodysplasia, and juvenile arteriopathy. In patients with major functional disability, operative treatment is recommended to remove the bony abnormality and repair the arterial lesion. ( info)
