1/7. Chondroma within the flexor tendon sheath of the index finger: case report.Chondroma of soft tissue is rare. We report a patient in whom a chondroma occurred within the flexor tendon sheath of the index finger. Magnetic resonance imaging showed the extent of the tumor, which wrapped around flexor tendons within the sheath, but did not invade either tendons or sheath. Total excision was done with preservation of the flexors and flexor tendon sheath. After the operation, the index finger had a full range of motion, and movement was painless.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
2/7. Osteochondromas associated with facial asymmetry and masticatory dysfunction: report of two cases.Two cases of solitary osteochondromas interfering with mandibular motion are presented along with a brief review of the literature. A single incidence of an osteochondroma developing from the mandibular condyle is added to the growing number of case reports. In addition, an osteochondroma developing from the zygomatic arch is reported. Our review of the literature has shown no previous report of occurrence at this site.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
3/7. Giant intraarticular loose bodies of the knee. Cases demonstrate spectrum of the lesion.Synovial chondromatosis is a well-known, well-described clinical and histopathologic entity. Occasionally, loose bodies in the knee joint can continue to grow and become large enough to impinge on joint motion. Extremely large synovial chondromata are relatively rare in the knee joint and have only been described in singular case reports in the orthopaedic literature. We describe two cases representing the spectrum of this disease process occurring in the popliteal fossa, simulating bony and/or soft tissue neoplasm. Case 1 demonstrates a large ossified chondroma, while Case 2 demonstrates a large chondroma without much calcification and with no ossification present. Because of the rarity of these lesions, preoperative staging studies, including CT scan, bone scan, and angiography, are usually warranted to help in the preoperative planning. Open biopsy with adequate tissue sampling is necessary to make an accurate histopathologic diagnosis. Once diagnosis is made, local excision for removal of the mechanical block to motion results in "cure"; local recurrence has not been noted.- - - - - - - - - - ranking = 2keywords = motion (Clic here for more details about this article) |
4/7. regeneration of an enchondroma defect under the influence of an implant of human bone morphogenetic protein.A 29-year-old woman with an enchondroma that was expanding and eroding the palmar cortex of the middle phalanx was successfully treated by curettage and implantation of bone morphogenetic protein. The metaphysis and cortex were repaired by lamellar bone within 2 months. The medulla was completely filled with trabecular bone by 9 months. The full range of motion and normal functions of finger and hand joints were restored, and there was no recurrence or abnormalities at follow-up visits 2 1/2 years after the operation.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
5/7. Epiphyseal osteochondroma of the anterior cruciate ligament.An 8-year-old Black boy complained of pain, swelling, and a decreased range of motion in the knee. One arthrotomy operation was reported to show a normal knee joint. Six months later, a second arthrotomy demonstrated an osteochondroma growing from the epiphysis into the anterior cruciate ligament. Epiphyseal osteochondroma should be added to the working differential diagnosis on children with effusion and decrease of knee motion.- - - - - - - - - - ranking = 2keywords = motion (Clic here for more details about this article) |
6/7. Osteochondromas of the hand in hereditary multiple exostosis: report of a case presenting as a blocked proximal interphalangeal joint.Blocking of motion of an interphalangeal joint in the hand by an osteochondroma has not been reported previously. Osteochondromas, which are uncommon in the hand, are encountered most frequently in patients with hereditary multiple exostosis. They can occur away from the epiphyseal plate region at the distal end of the proximal and middle phalanges. Osteochondromas that occur in these locations characteristically cause angular and rotational deformities. Early recognition and prompt surgical treatment in this child resulted in full motion with minimal angular deformity.- - - - - - - - - - ranking = 2keywords = motion (Clic here for more details about this article) |
7/7. Scapulectomy for the treatment of malignant tumors of the scapula.Two cases of Tikhor-Linberg resection for rhabdomyosarcoma and malignant chondromyxoid fibroma and two cases of scapulectomy for metastatic disease of the shoulder girdle are reviewed. After resection of the scapula, active motion of the shoulder will be severely restricted, but normal function of elbow, wrist, and hand permit use of the extremity in many activities of daily living. Surgical treatment for metastatic bone disease in the upper extremity and the role of radiation therapy for metastatic bone disease are discussed.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
