We describe a male patient, who was seen for the first time at the age of 8 years because of short trunk dwarfism. Spine radiographs showed platyspondyly with irregular areas of increased and decreased mineralization (irregular spotted appearance within lytic lesions located along the posterior vertebral bodies of the entire spine). ⋯ At the age of 17, progressive spine stiffness associated with stooping posture developed. 3DCT scanning showed pathological transformation of the spinal enchondromas into generalized ossification and thickening of the posterior vertebral elements (vertebral laminae, supraspinal, and interspinal ligaments, respectively) causing effectively the development of a diffuse posterior spinal ankylosis. We report what might be a unique subtype of spondyloenchondrodysplasia (Spranger type IV).

To quantify the dimensions of the atlas pedicles and to analyze the relationship between extra medullary height (EMH) with intra medullary height (IMH) of the atlas pedicle. ⋯ The EMH and the IMH of the atlas pedicles were measured by using CT images of the atlas, providing anatomic parameters for surgery. They showed a certain correlation but with a high variability. C1 pedicle screw fixation was well performed when the medullary canal was ≥1 mm, but the surgical procedure should be careful when it was between 0 and 1 mm, and avoided when there was no medullary canal in the atlas pedicle! So 3D CT reconstruction should be conducted to obtain data and establish individualized fixation strategy preoperatively.

Duplication of the spine is very rare, and this malformation is generally considered as a severe form of type I split cord malformations. To the best of our knowledge, this is the first reported case of spine duplication associated with lipomyelomeningocele. ⋯ A surgical operation was planned to release the tethered cord and instrumentation and fusion for scoliosis; however, the operation was declined by the patient.

Despite the high prevalence of musculoskeletal diseases, in Spain there are few data about how these conditions affect the quality of life of individuals. The objective of this study was to assess the quality of life (QOL) of patients candidate for orthopedic surgical treatment using an age-gender adjusted method of QOL scores. ⋯ Presenting the results of SF-36 in standard deviations from the age- and gender-adjusted population mean (T values) leads to a better appreciation of the differences between the various diseases. Patients candidate for surgery of the lumbar spine had a worse QOL, while the QOL in patients candidate for knee arthroplasty was the least affected.

We retrospectively investigated the radiographic findings in patients with atlanto-axial subluxation (AAS) due to rheumatoid arthritis, and clarified the effect of reduction of the atlanto-axial angle (AAA) on the cranio-cervical and subaxial angles. ⋯ A proper reduction of the AAA did not affect the cranial angles or induce kyphotic malalignment of the subaxial region after atlanto-axial arthrodesis. However, if we can obtain a significant and large reduction of AAA in patients showing kyphosis before surgery, then this reduction will be offset in the atlanto-occipital joint and we should therefore pay special attention to its morphology after surgery.
