High Prevalence Of Lumbar Spinal Stenosis In Cases Of Idiopathic Normal-Pressure Hydrocephalus Affects Improvements In Gait Disturbance After Shunt Operation London Spine Lumbar Stenosis

The article discusses a study that sought to determine the coexistence rate of lumbar spinal stenosis (LSS) in patients with idiopathic normal-pressure hydrocephalus (iNPH). iNPH is characterized by symptoms of dementia, urinary incontinence, and gait disturbance, but the gait disturbance tends to persist after shunt surgery. Gait disturbance and urinary dysfunction are also major symptoms of LSS. The study included 224 patients diagnosed with iNPH and found that 32.6% of them also had LSS. The presence of LSS did not affect the postoperative improvement rates of dementia and urinary dysfunction, but it significantly impaired the improvement in gait disturbance. The study concludes that gait disturbance in iNPH patients should be considered a potential complication of LSS

CONCLUSIONS: LSS affects improvements in gait disturbance of iNPH patients after shunt operation. Because our results revealed that one-third of iNPH patients were associated with LSS, gait disturbance observed in iNPH patients should be considered a potential complication of LSS.

Abstract

Objective: Idiopathic normal-pressure hydrocephalus (iNPH) is characterized by symptoms of dementia, urinary incontinence, and gait disturbance; however, gait disturbance tends to persist after shunt surgery. Gait disturbance and urinary dysfunction are also major symptoms of lumbar spinal stenosis (LSS). Currently, the epidemiology of the complications of LSS in iNPH is unclear. Here, we evaluated the coexistence rate of LSS in iNPH cases.

Methods: This was a retrospective case-control study. Between 2011 and 2017, 224 patients with a median age of 78 years, including 119 males, were diagnosed with iNPH and underwent lumboperitoneal shunts or ventriculoperitoneal shunts. LSS was diagnosed with magnetic resonance imaging by two spine surgeons. Age, sex, body mass index (BMI), Timed Up and Go (TUG) test, Mini Mental State Examination (MMSE) score, and urinary dysfunction were examined. We compared the changes in these variables in the group of patients with iNPH without LSS versus those with both iNPH and LSS.

Results: Seventy-three iNPH patients (32.6%) with LSS had significantly higher age and BMI. The existence of LSS did not alter the postoperative improvement rates of MMSE and urinary dysfunction; however, TUG improvement was significantly impaired in the LSS-positive group.

Conclusions: LSS affects improvements in gait disturbance of iNPH patients after shunt operation. Because our results revealed that one-third of iNPH patients were associated with LSS, gait disturbance observed in iNPH patients should be considered a potential complication of LSS.

High prevalence of lumbar spinal stenosis in cases of idiopathic normal-pressure hydrocephalus affects improvements in gait disturbance after shunt operation

Sciatica My mother was in absolute agony for more than 3 months due to sciatica. It just came out of nowhere and took her out of action. From working full time she went straight to being bed bound and unable to carry out simplest of actions.The pain was 9/10 and she was bed bound for those three months. Multiple trips to A&E and GP and they wouldn't class it as an emergency therefore they wouldn't do anything about it other than upgrading the painkillers which did next to nothing for my mother. I couldn't bear to watch my mother sleeping on A&E bench in pain for 7 hours, just to be told by doctors that she wouldn't be kept in. I remember her joining her hands and begging the doctors to stop the pain which broke my heart. I then started doing research on google and London spine unit came up with Dr Mo AKMAL's profile and review. First meeting with Dr AKMAL was via ZOOM as my mother was bed bound. Dr AKMAL spoke to me and my mom and told us that this is nothing to worry about and that the pain would be 100% gone.Dr AKMAL assured us to visit the hospital so he could physically inspect my mother and give us the best solution. One trip to the london spine unit and Dr AKMAL advised us that the best solution would be to carry out Minimally invasive disectomy. Dr AKMAL advised that due to my mother being bed bound for a while, steroid injection might not give the result that my mother wishes. Dr AKMAL was very confident and showed us some videos from other patients who had gone through the same ordeal. The biggest thing i noticed between before and after was the smile on the patients face. Dr AKMAL was constantly assuring my mother throughout the meeting that he would take care of her pain and gave her 100% confidence that the result would be delivered.He promised her that she would be walking pain free the same day after the operation. Before the operation Dr GURUNG was consulted multiple times and he also was very helpful. Right after the surgery, as Dr AKMAL promised, my mother was walking and the biggest thing was that the pain was gone. My mother had forgotten to smile for three months and there i saw her smiling again. Dr AKMAL and Dr GURUNG gave us brilliant aftercare and informed us that just give them a ring if there was any issue. Its been several weeks now and my mother is heading towards complete recovery without any issues. The pain is completely gone and anyone who is reading this going through the same horrible sciatica pain you must come and see Dr AKMAL. Thank you Dr AKMAL and your whole team for helping my mom achieve this pain free life.
