Several catheter problems have been reported as causes of baclofen pump malfunction; however, a tangled catheter has never been described. ⋯ Although the exact mechanism of this complication is unknown, the friction-compression of the catheter against the iliac bone may be the cause. Implanting the pump away from the bony formation may avoid catheter entanglement.

Case Reports
C1 arch regeneration, tight cisterna magna, and cervical syringomyelia following foramen magnum surgery.
Although bone regrowth following craniocervical decompression has been rarely reported to cause late recurrence of Chiari symptoms, syringomyelia has not been observed in such cases. We report a unique case of cervical syringomyelia resulting from spontaneous regeneration of the posterior C1 arch after foramen magnum decompression. ⋯ Spontaneous bone regrowth and arachnoid scarring may lead to the development of cervical syringomyelia several years after foramen magnum surgery. Neurosurgeons should be aware of this rare complication whose management is similar to that of Chiari malformations, namely craniocervical decompression and establishment of a patent foramen of Magendie.
