L5 radiculopathy caused by L5 nerve root entrapment by an L5-S1 anterior osteophyte
BACKGROUND L5 radiculopathy is a common problem that has several causes. Entrapment of the L5 nerve root by anterior osteophytes at the L5-S1 junction is rarely reported. Posterior decompression of the L5 nerve root is commonly performed, but anterior decompression of the L5 nerve root is not a frequently performed procedure. The purpose of this case report is to describe an uncommon case of L5...
متن کاملAlternative technique of cement augmentation of loosened pedicle screws -- technical note and presentation of two cases.
An alternative cement augmentation technique for pedicle screws is described, which was applied in two patients with mono- and bisegmental non-union after preceding multisegmental lumbar fusion. The correctly placed pedicle screws in S1 with diameters of 6 and 8.5 mm had severely enlarged the screw cavities due to segmental instability. Revision screws with 10 mm diameter demonstrated sufficien...
متن کاملLower Extremity Radicular Pain Caused by Entrapped Sigmoid Colon Between L5 and S1 Vertebrae.
Intestinal entrapment between two vertebral bodies is very rare. In all previous cases, it occurred by major trauma. However, the bowel entrapment between two vertebral bodies without trauma has never been reported, not to mention as the cause of lower extremity radicular pain. We describe the case of an 82-year-old female patient with right lower extremity radicular pain without recent trauma ...
متن کاملNerve injury caused by mandibular block analgesia.
Fifty-four injection injuries in 52 patients were caused by mandibular block analgesia affecting the lingual nerve (n=42) and/or the inferior alveolar nerve (n=12). All patients were examined with a standardized test of neurosensory functions. The perception of the following stimuli was assessed: feather light touch, pinprick, sharp/dull discrimination, warm, cold, point location, brush stroke ...
متن کاملL5 – S1 Segmental Kinematics After Facet Arthroplasty
BACKGROUND Facet arthroplasty is a motion restoring procedure. It is normally suggested as an alternative to rigid fixation after destabilizing decompression procedures in the posterior lumbar spine. While previous studies have reported successful results in reproducing normal spine kinematics after facet replacement at L4-5 and L3-4, there are no data on the viability of facet replacement at t...
