PURPOSE: Mucopolysaccharidosis (MPS) are uncommon inherited metabolic ailments, inflicting lysosomal storage of mucopolysaccharides; scientific presentation entails skeletal system and significantly the backbone. Anomalies embrace growing kyphosis at thoracolumbar junction, that may causes nervous signs, and dens hypoplasia with related atlantoaxial subluxation that may trigger myelopathy. We current our expertise within the therapy of backbone pathology in MPS.
METHODS: Medical therapies of MPS appear to have little impression on backbone illness: therapy of cervical instability usually contains surgical decompression and stabilization, as in affected person MPS1 that we current, whereas thoracic lumbar kyphosis is handled by bracing and, in extreme instances, with surgical procedure. Bracing is more practical in kyphosis beneath 40° Cobb. Our surgical instances with thoracic lumbar kyphosis over 40° Cobb, therapy embrace the primary one ever described by solely posterior strategy with vertebrectomy in MPS and a case of lateral costo-transverse strategy instrumented correction.
RESULTS: Surgical sufferers had no main problems after surgical procedure and CT scan at follow-up confirmed full fusion with out lack of correction, even when in a cervical case we used an grownup inflexible instrumentation in a 4 year-and-six month-old woman (11 years follow-up) and in thoracic lumbar kyphosis case handled by vertebrectomy attributable to diminutive anatomy we positioned interbody cage in suboptimal place.
CONCLUSIONS: Bracing is a viable therapy technique in thoracic lumbar kyphosis and may receive good scientific outcomes at medium phrases follow-up even when kyphosis deformity stays in radiographs. Surgical therapy is efficient in extreme evolving instances each at cervical and thoracic lumbar degree, predominant difficulties arose from unavailability of devoted instrumentation in very younger affected person, as even smallest gadgets accessible are sometimes too massive.
