[Recurrent chronic multifocal bone infection].

We present a 9-year-old girl who had chronic recurrent multifocal osteomyelitis. The bones involved were: right clavicle, distal fibula (bilateral), left sacroiliac and right wrist. After 10 years of follow-up; she is asymptomatic but presents radiological evidence of lesions in the right clavicle and left sacroiliac joint. The diagnosis was made by exclusion criteria. The biopsy and results of cultures from various bones were negative 4 times. Although chronic recurrent multifocal osteomyelitis is rare, it should be considered in the differential diagnosis of acute or chronic osteomyelitis and neoplasma. Its recognition avoids unnecessary laboratory tests and antibiotic therapy.

[Fracture of the humerus after hemiarthroplasty of the shoulder].

Fracture of the humeral shaft as a complication of total shoulder replacement or shoulder hemiarthroplasty is infrequent, but has serious consequences. Traumatic injury is the most common reason for humeral fracture. The prosthesis causes corticolysis as a result of aseptic and septic loosening. Concomitant with increasing use of total and hemiarthroplasty of the shoulder, is an increase in aseptic loosening of the prosthesis. This increases the frequency of humeral fracture after the procedures. We reviewed the results of 3 patients, women aged 54 and 68 years, respectively, and a man of 65, who were treated for humeral fracture as a complication of hemiarthroplasty of the shoulder. We recommend surgical treatment for fracture around the tip of the prosthesis. Humeral fracture below the tip of the prosthesis should be treated individually, depending on the surgeon's experience.

Arthroscopic assistance for unselected tibial plateau fractures.

Nine closed tibial plateau fractures in nine patients were treated with arthroscopic-assisted reduction and percutaneous fixation or buttress plate. These procedures were performed between 1993 and 1994 and represent an exclusive and nonselected, consecutive series. The mean follow-up period from time of operation was 10.6 months (range, 6 months to 1.5 years). The results were satisfactory. All the reductions remained roentgenographically anatomic with good to excellent clinical function. Concomitant knee pathology included three cases of partial tear of the anterior cruciate ligament that required special postoperative treatment, and two cases of partial tear of the lateral meniscus that were treated arthroscopically. There were no intraoperative complications. There was one case of postoperative peroneal nerve neuropraxia that resolved spontaneously. Our conclusion is that this technique should be considered as a treatment alternative in the treatment of tibial plateau fractures.

[Posterior approach for excision of sacral chordoma].

Chordoma is considered to be a malignant, fatal tumor. According to most authors it constitutes between 1-4% of all malignant bone tumors. In 50% of the cases it is located in the sacrum, in 35% in the cervical spine and skull, and in 15% in the thoracic spine and elsewhere. It is an aggressive, locally invasive, slowly-growing tumor. Although metastases are rare, when they occur they are of an anaplastic type, especially in the lungs, liver, regional lymph nodes, skin and muscles. Chordoma is a rare tumor, and its location and slow growth often result in delayed diagnosis. Complete excision of the chordoma was formerly considered impossible. There is often local recurrence, and often, by its very nature, excision results in neurological defects. Lately, there is more optimism regarding complete cure, due to more advanced surgical methods. We present a 66-year-old man in whom a tumor developed in the sacrococcygeal area and the right buttock. The tumor was diagnosed by CT, MRI and biopsy as a chordoma of the sacrum, without intra-abdominal infiltration. He was operated through a posterior approach, with complete resection of the tumor, including almost the whole sacrum and the coccyx. We consider this approach simpler than the abdominal-dorsal approach, which in cases of intra-abdominal infiltration is necessary. We regard this simple incision as a significant advance in the treatment of this condition.(ABSTRACT TRUNCATED AT 250 WORDS)
