Foot deformities in diastrophic dysplasia. An analysis of 102 patients.

The exceptionally high prevalence of diastrophic dysplasia in Finland has enabled us to analyse the foot deformities of 102 patients at their first orthopaedic evaluation and classify 204 feet into five categories. The most common finding (43%) was a foot with tarsal valgus deformity and metatarsus adductus; 37% showed either equinovarus adductus (29%) or equinus (8%) deformities. At the first examination 13% showed metatarsus adductus deformity alone, and 7% were clinically normal. The expression 'club foot', generally used for the foot deformity in diastrophic dysplasia is a misnomer. There is a wide spectrum of deformities, some of them specific for the condition.

The spine in diastrophic dysplasia.

Diastrophic dysplasia is an autosomal recessive disorder of the skeleton, characterized by disproportionate short stature, generalized joint deformities, club feet, deformed ear pinnae, and, frequently, spinal deformity and cleft palate. Diastrophic dysplasia is more common in Finland than elsewhere. We studied 101 patients with an age range from newborns to 79 years to find out the frequency and type of spinal deformities, the early signs of progressive cases, and to follow the natural history of the disease. In the follow-up study, 17 patients were under 10 years, 21 under 21 years, and 63 over 21 years of age. One-third of the patients had cervical kyphosis; in the most severe case the kyphosis was 180 degrees and led to quadriplegia during anesthesia. In three patients, cervical kyphosis resolved spontaneously before the age of 5 years. The overall frequency of scoliosis was 37%; 49% in women and 22% in men. Only 13 patients had curves greater than 50 degrees; these curves constituted distinct rotation at the apex from the early evolution of the curve. The early signs of severe curves were detectable at the age of 2 to 4 years. Only two patients were operated on because of scoliosis; one with fusion in situ and the other instrumented with the pediatric Cotrel-Dubousset instrumentation. Three patients had a brace, which did not prevent the progression of the curve. Symptoms referring to a narrow spinal canal were registered in four patients, two of which were operated on; a lumbar posterior decompressive procedure was made at adult age.

Twenty-six early operations in brachial birth palsy.

26 babies with brachial birth palsy were operated on at the age of 12-275 days (mean 75 days) in paediatric surgical departments of Helsinki (12 cases) and Turku (14 cases) University Central Hospitals during years 1970-1985 using microsurgical techniques. Epineuroraphy was used in 9, interfascicular nerve grafting in 7, neurolysis in 7, and intercostal neurotisation in 3 cases. The functional status of the upper extremity was recorded 1 to 14 years after the operation using a modified Mallet's classification: 6 were good, 17 fair and 3 poor. The outcome after epineuroraphy was similar to interfascicular grafting. One intercostal neurotisation resulted in fair function and 2 in poor, but the result in target function, i.g. in the peripheral neurotised nerve, was good.

Ten years' experience in patients with osteogenic sarcoma in Finland.

Ten years' results of 56 patients with high grade osteogenic sarcoma are reported. Fifty-two patients had M0 disease. Immediately after open biopsy the patients were treated with chemotherapy using modified Rosen's protocols T4, T7 and T10. The primary tumor was adequately removed in most patients. Six children were treated with limb saving. The actuarial and disease-free survival was 80% after 1 year, and 73% to 8 years. Two patients died because of toxic side effects of chemotherapy, one of septicemia, the other of late cardiac failure secondary to doxorubicin.

Fractures of the proximal femur in Finland in 1975.

Hospital admissions due to fractures of the proximal femur in Finland increased 50% between 1968 and 1976. In this study the established differences and results of treatment in regional and district hospitals are reviewed. From the mortality incidence and the length of hospitalisation, the results were better in regional than in district hospitals, and better for operatively than for conservatively treated patients. Of the different operative methods, the best primary results were obtained with endoprosthetic replacement and osteosynthesis with a fixed-angle nail plate.

Oculodentodigital dysplasia syndrome. Report of four cases.

Four cases of oculodentodigital dysplasia are reported. Three cases are from the same family, father and two daughers. These three cases have the characteristics typical of this disorder: narrow nose, hypoplastic alae nasi, microphthalmia, defects of the teeth, syndactylyl of the IV and V fingers, and skeletal anomalies. The fourth case differs from the earlier reported cases; he has all the typical findings of oculodentodigital dysplasia but in addition he shows features not previously reported, namely exceptionally poor vision, mental retardation, monilethrix and pili annuli changes of the hair.

The knee in arthrogryposis multiplex congenita.

The functional, radiological, and ambulatory status of 30 patients (58 knees) with arthrogryposis multiplex congenita (AMC) were analyzed after a follow-up of 1-36 years. The muscular imbalance presented in many of these patients corresponded well to the type of deformity. The primary treatment was nonoperative in most cases. In spite of the initial promising results, a significant number of patients underwent operation for residual symptoms. Treatment of flexion contractures seems to be more discouraging than the treatment of extension contractures. On the other hand, the risk for degenerative arthritis seemed to be elevated, especially in the extension-contracture group.
