Radiography of the carpal scaphoid. Experimental evaluation of "the carpal box" and first clinical results.
RATIONALE AND OBJECTIVES: The authors describe a new device ("the carpal box") for the radiographic detection of occult scaphoid fracture. METHODS: Fractures in the scaphoid of five cadaver specimens were mechanically produced. Subsequent examinations included conventional scaphoid radiography, multi-angle radiography, and radiography using the new device. The anatomic analysis of the specimens served as the standard for comparison. A pilot study was performed in six consecutive patients with suspected scaphoid fracture. RESULTS: Neither scaphoid radiography nor multi-angle radiography could confirm a fracture in two specimens, whereas all fractures were recognized on the carpal box radiographs. All scaphoid fractures were visualized by carpal box radiography, whereas scaphoid radiography was equivocal in one patient and negative in the other. CONCLUSIONS: Carpal box radiography may have additional value in the diagnosis of occult scaphoid fracture. This may lead to a reduction in costs and inconvenience for patients with clinically suspected scaphoid fracture and negative scaphoid radiography.

MCA/MR syndrome in two female siblings: new entity or variant examples of Coffin-Lowry versus Atkin-Flaitz syndromes?
We report two sisters with mental retardation, coarse facial features, telecanthus, flat malar region, prominent lower lip, kyphoscoliosis, and tapering fingers. Although these patients' phenotypes showed considerable overlap with the Coffin-Lowry and the Atkin-Flaitz syndromes, their overall picture makes these diagnoses controversial.

Metacarpophalangeal pattern profiles: Q-score for ages from birth to 7 years.
The metacarpophalangeal pattern profile (MCPP) analysis is a widely used method of standardization of bone length measurements to quantify congenital skeletal dysplasia of the hands. A main source of inaccuracy is the prominent scatter in the values of the standard deviation (S.D.) of the reference length, which is used in the calculation of the standardized values (Z-scores). Other sources of error, especially when bone length measurements of younger children are evaluated, are the rather large variability in the age of appearance of the epiphyses of the different bones, and the use of tabulated reference data which are available only at one-year intervals. We have devised another method of standardization of bone length measurements, by calculating the Q-score. Its advantages are that no S.D. values are needed and that more accurate results are obtained. Moreover the interpretation of the Q-scores is more straightforward than the interpretation of the Z-scores. Q-scores for 3 patients with Sotos syndrome are presented. Use of the MCPP in the form of the Q-score, will probably make it an even stronger tool than before.

Metacarpophalangeal pattern profile analysis in Rubinstein-Taybi syndrome.
Metacarpophalangeal pattern profile (MCPP) was determined in 49 radiographs of 40 patients with Rubinstein-Taybi syndrome. Two recognizable hand profiles were seen, depending on the configuration of the thumb and on age. Patients with a straight thumb showed a short first proximal phalanx, and short third medial phalanx. Patients with a radially deviated thumb had a short first proximal phalanx. Depending on age, a relatively large (infancy) or markedly short (older patients) first distal phalanx was found. The similarity between the patients was high. A third group of patients did not show a particular hand profile, but only small hand bones. The pattern variability indices were high in all groups of patients. MCPP analysis in Rubinstein-Taybi syndrome seems to be a powerful, but not pathognomonic, diagnostic tool.

The prenatal development of the normal human skeleton: a combined ultrasonographic and post-mortem radiographic study.
Post-mortem radiography of fetuses with skeletal dysplasia is essential for diagnostic classification. Interpretation of the radiographs should be based on the knowledge of morphology and dimensions of the normal skeleton in all stages of development. A retrospective post-mortem radiographic study is presented with measurements of the lengths of the long bones and thoracic and lumbar spine. The study included 69 fetuses and neonates with a normal skeleton, whose gestational age ranged from 13-42 weeks and who died perinatally or lived for less than one week. The measurements of the long bones were plotted on growth curves obtained from a prospective longitudinal ultrasonographic investigation of another group of 63 normal fetuses from 12-40 weeks of gestation. Thoracic and lumbar spine measurements by ultrasonography were not available. The radiographic data of thoracic and lumbar spine were, therefore, compared to radiographic studies from the literature. No disagreement with these studies was found. It can be concluded that measurements of bones from standardized post-mortem radiographs in cases of questionable gestational age or defects of bone development can be compared with ultrasonographic measurements. To illustrate the usefulness of the graphs, 13 fetuses with various types of skeletal dysplasia were evaluated retrospectively.

Cystic rheumatoid arthritis: description of a nonerosive form.
In a study of patients with rheumatoid arthritis (RA), 9% (n = 70) were found to have a cystic form. At radiologic examination of these patients with cystic RA, the first abnormality seen consisted of periarticular intraosseous cysts without erosions. The cysts were distributed symmetrically, most often located at the proximal side of the joints and predominantly around the proximal interphalangeal, metacarpophalangeal, and wrist joints of the hands and the first interphalangeal and metatarsophalangeal joints of the feet. Computed tomographic scans showed the peripheral intraosseous location of the cysts. Magnetic resonance images showed that the cysts may contain fluid, inflamed synovia, or both. Cysts can be an important feature in the diagnosis of RA and a supplement to the criteria of the American Rheumatism Association. Osteoporosis, joint-space narrowing, and joint destruction occurred less frequently in patients with cystic RA than in patients with classic RA. Of the patients with cystic RA, 54% were male, and 50% were seronegative. This study is a supplement to and an enlargement on earlier descriptions of cyst predominance in RA.

Complex motion tomography of the sacroiliac joint. An anatomical and roentgenological study.
To find a better method for diagnosing sacroiliac (SI) joint disease, an anatomical approach was combined with conventional roentgenology, complex motion tomography and computed tomography. Complex motion tomography is suggested as the method of choice in the investigation of the SI-joint. Because of its complex (sinusoidal) form, the dorsal portion of the joint has to be tomographed in frontal projection and the middle and ventral portions in oblique projection. In 56 patients, referred for probable ankylosing spondylitis, 72 SI joints were investigated. Based on plain radiography six and on frontal tomography five SI joints were diagnosed as normal. However, based on oblique tomography 31 joints were diagnosed as normal.

The venous phase in hand angiography.
It has been found that the venous phase of hand angiography can be reliably visualized with metrizamide. There are indications that the venous phase can provide important information on the validity of fingers with arterial occlusion.

Hereditary malformation of the toes and fingers in a family with double translocation heterozygosity.
A hereditary malformation of the metatarsophalangeal joints, called here "tear drop" deformity, and a cut off appearance of the distal phalanges of the toes is described in a family with double translocation t (7; 12), t (2; 6) heterozygosity. A bracydactyly E was also found. These disorders seemed unrelated to the chromosomal aberration.

Double translocation t(7;12),t(2;6) heterozygosity in one family. A contribution to the trisomy 12p syndrome.
Double translocation heterozygosity t(2;6),t(7;12) in three generations of a Dutch family is described: the segregation of a double translocation in more than one generation has not been previously published. The index case was a 16-year-old mentally retarded boy with partial trisomy 12p who showed several dysmorphic features such as high prominent forehead, flat face, flat and short nose bridge, short nose, dysplastic ears, prominent lower lip, and several skeletal abnormalities. Based on the findings in this patient and those in nine other cases, the existence of a specific trisomy 12p syndrome is postulated.
