Cervical pseudarthrosis in ankylosing spondylitis. A case report.

STUDY DESIGN: This report illustrates two different cases of cervical pseudarthrosis in ankylosing spondylitis. OBJECTIVES: To point out the extreme rarity of this condition at cervical level, to discuss the pathogenesis, and to stress the necessity of surgical management. SUMMARY AND BACKGROUND DATA: Pathogenesis of pseudarthrosis in ankylosing spondylitis is discussed. Several factors are involved: trauma, which may be major or minor and undetected; stress fracture; and inflammatory changes. Major trauma was the cause of pseudarthrosis in the first patient, whereas stress fracture and inflammatory changes were the probable causes in patient 2. In patient 1 there were signs and symptoms of cord compression. Patient 2 was referred because of functional disability resulting from kyphosis and because of potential neurologic risk. METHODS: Cervical fusion was performed in both patients. Patient 1 underwent posterior fusion; patient 2 had combined fusion. Patient 1 also underwent a lamineotomy. RESULTS: The course of the disorder after surgery was uneventful in both patients. Neurologic symptoms subsided in patient 1; kyphosis was corrected in patient 2. Both patients resumed their preoperative activities. Follow-up evaluation was done 6 years after surgery in patient 1 and 2 years after surgery in patient 2. CONCLUSIONS: Pseudarthrosis of the cervical spine in ankylosing spondylitis is extremely rare. Presentation of the two patients was different in terms of pathogenesis and signs and symptoms. Surgical treatment is advocated for this disorder.

[Treatment of the dislocated hip from walking age to 5 years].

Review of 93 previously not-treated congenital dislocations of the hip, followed at the Institute Calot between 1965 and 1985. Three dislocations were treated by immediate surgical reduction and for the remaining 90 cases, the basic treatment was orthopedic reduction followed by innominate osteotomy. Femoral derotation osteotomy was also performed in 13 cases. Out of them 6 with various effect. Surgical reposition was necessary in 9 cases. The main technical aspects and problems are described. The complications were: abnormal development of the superior femur: 4 cases. Recurrent luxation and subluxation: 5 cases. Early fusion of the triradiate cartilage: 13 cases. Mostly transitory stiffness: 17 cases. Superficial sepsis: 7 cases. Greenstick fractures: 5 cases. Forty five hips were reviewed at the end of the growth period. The sphericity of the femoral head was evaluated according to the criteria of Mose and the coverage of the head according to the criteria of Lequesne. The results were presented according to the classification of Séverin, modified by Robert and Seringe with additional criteria of Mose for evaluation of the morphology of the head. Out of 45 cases there were 36 normal hips (80%), with 12 perfect hips.

Bone and joint tuberculosis: a review of 652 cases.

The results of a computerized study of 652 cases of bone and joint tuberculosis were presented. The cases were studied according to a program of 76 variables. From the various results of such a study, the following data were found. A high rate of tuberculous osteomyelitis (19%) and of tuberculosis of the upper limb joints (14%) were found. The reliability of a new x-ray classification based on the degree of destruction of the joint should be emphasized along with the reliability of biological examinations. All patients were treated according to the same principles; chemotherapy against tuberculosis, and surgical measures against musculoskeletal destruction. The results were excellent for tuberculosis. A favorable response to chemotherapy was found in 98% with only 3% of the cases relapsing. Anatomical results were surprisingly good and excellent in 56% of the cases, in spite of the low rate of surgery performed. Fair anatomical results often gave good functional results if no deformity persisted.

[Results of the conservative treatment of 171 cases of Pott's disease without neurologic involvement].

One hundred and seventy-one patients suffering from Pott's disease of the spine were treated by the same surgeons between 1965 and 1985. Chemotherapy, which varied during the period, was given in every case. Plaster immobilization was only used in the first 41 patients, until the authors concluded that it did not prevent worsening of the kyphosis. For technical reasons, surgical treatment was not used in any of these 171 patients. The results showed, in children, not only the usual development of kyphosis in the course of treatment but worsening later in the course of growth. For this reason, arthrodesis by the anterior route should be considered to obtain early fusion when the facilities and technical skills are available. In adults, the indications for surgery are more limited. Whilst there is a risk that kyphosis may reach a mean of 20 degrees during conservative treatment, it does not increase later. The authors conclude that it is necessary to link the indications for surgery to the availability of facilities at each individual hospital called upon to treat these patients.
