A 7-yr-old girl presented with progressive shortening of the right upper arm and limitation of shoulder motion. Pseudohypoparathyroidism associated with Albright's hereditary osteodystrophy was diagnosed by biochemical, hormonal and radiographic studies. Her condition was complicated by severe humerus varus on the right side. Proximal humeral valgization osteotomy and concomitant humeral lengthening resulted in an improvement of the shoulder joint motion and activity in daily life.

We analyzed plain radiographs of 591 normal adult hips of various parameters to evaluate the radiological characteristics of the hip joint including the center-edge (CE) angle, acetabular angle, acetabular depth, acetabular roof obliquity and roof angle, and also to verify the rate of acetabular dysplasia. The CE angle was negatively correlated with acetabular angle and acetabular obliquity, but it was positively correlated with acetabular depth and roof angle. The rate of acetabular dysplasia (CE angle<20 degrees) was 1.8%. We concluded that the CE angle and acetabular angle are more useful parameters for the diagnosis of acetabular dysplasia because there was no significant difference with advancing age and gender, as well as relatively small standard deviations.

OBJECTIVESTo investigate clinical appearance and radiological characteristics of high grade developmental spondylolisthesis and their significance.

METHODSIn a retrospective study, a group of 6 female patients, who were diagnosed as high grade developmental spondylolisthesis and treated in Peking University third hospital from March 2007 to December 2008 were included. Clinical and radiological characteristics of the 6 patients were investigated and the following parameters were measured on standing lateral X-ray: PI (pelvic incidence), SK (sacral kyphosis) and LL (Lumbar lordosis). A series of 44 patients who came to out-patient department due to LBP and had no positive findings on lateral lumbar X-ray were selected as the control group. The four parameters were compared between study group and control group. Clinical meanings of significant difference were discussed.

RESULTSClinical findings of high grade developmental spondylolisthesis included bending of knees, deformity of trunk and sciatica. Radiological appearances were characterized with kyphosis of lumbo-sacral joint, retroverted pelvis and domed sacrum. Spondylolisthesis patients has an average PI of (52 +/- 7) degrees which was significant higher than the control group [(43 +/- 8) degrees ] (P < 0.01). LL of study group [(51 +/- 10) degrees ] was higher than that of the control group [(18 +/- 9) degrees ] (P < 0.01) and SK of the study group [(12 +/- 11) degrees ] were lower than that of the control group [(21 +/- 10) degrees ] (P < 0.05).

CONCLUSIONSCharacteristics of clinical findings of spondylolisthesis patients have obvious cosmetic appearance, significant pain and lower neurological deficits. Radiological characteristics display deformity of lumbo-sacral joint. PI, LL and SK are significant parameters for high grade spondylolisthesis.

Scurvy is very rare disease in industrialized societies. Nevertheless, it still exists in higher risk groups including economically disadvantaged populations with poor nutrition, such as the elderly and chronic alcoholics. The incidence of scurvy in the pediatric population is very low. This study reports a case of scurvy in a 5-year-old girl with cerebral palsy and developmental delay based on MRI findings.
