We report the use of a self-help intermittent balloon catheter device in paraplegia with palsy in both ulnar nerves. A 77-year-old man developed paraplegia and neurogenic bladder dysfunction following postoperative complication of a thoracic aortic aneurysm. Palsy in both ulnar nerves was found in the medical history. Self-catheterization was necessary as urination control for neurogenic bladder dysfunction using an intermittent balloon catheter for nocturia. However, it was difficult for the patient to grasp the reservoir and inject fixed water into the balloon, and to clamp it while maintaining injection due to the ulnar nerve palsy. In addition, the clamp was easily dislodged by nighttime patient rolling, and the reservoir caused insomnia. Therefore, we removed the clamp and the reservoir and we installed an FF connector and a closed needleless connector and used a lock-syringe for fixative infusion. Subsequently, patient self-operation became easy, and the clamp did not come off when the lock-syringe was removed, and the patient's distress caused by the reservoir also disappeared.

Patient 1, a 75-year-old woman with a past history of osteoarthritis of the right knee and Parkinson disease, had a subarachnoid hemorrhage. She complained of right knee pain during her rehabilitation. It turned out that she had sustained a right trochanteric fracture after falling out of bed in another hospital. Patient 2, an 86-year-old woman with a past history of rheumatoid arthritis, was treated with the Gamma nail technique for a left trochanteric fracture. She described experiencing pain in the region from the left knee to the lateral side of the left thigh during her rehabilitation, about two months after the hip operation. X-ray and computed tomography images showed varus displacement of the femoral head due to screw cut-out. In each of these cases, it took some time for us to detect the underlying hip diseases. The dermatome shows regions of the skin innervated by each single spinal segment. Similarly, the sclerotome shows regions of bone and periosteum innervated by each single spinal segment. According to Inman and Saunders's sclerotome, the proximal portion of the femur is mainly innervated by L3, L4 and L5. On the other hand, in dermatome perspective, L3, L4 and L5 innervate the knee and region around the knee. It means that hip diseases can cause referred pain to the knee.Untypical pain in distant regions from the hip joint makes it difficult to examine the hip joint and causes delay in an accurate diagnosis, as in the cases just described. Therefore, we should keep in mind that hip diseases can cause referred pain to the knee.

A 47-year-old male with a left middle cerebral artery embolism due to a left atrial myxoma was admitted to our hospital for severe right hemiparesis (Brunnstrom Recovery Stage I in all parts) and total aphasia. On day 29, the tumor was extracted but he developed complete AV block as a complication after surgery. Rehabilitation was delayed for a long time and the severe hemiparesis remained unchanged. He required assistance even when taking a sitting position on the bed, but muscle tonus appeared on the right lower limb. Beginning on day 59, before pacemaker implantation, we applied high-frequency repetitive transcranial magnetic stimulation to his bilateral lower limb motor areas for 5 consecutive days. As a result, paresis in the right lower limb improved to Brunnstrom Recovery Stage III and he could walk between parallel bars. On day 67, a pacemaker was implanted. On day 88, he could walk independently with a cane on discharge from our hospital, although the upper limb and hand paresis remained severe. Although there has been no report on the use of transcranial magnetic stimulation on the lower limb motor area except in the chronic stage, our experience suggests that this type of intervention can be effective in the recovery stage as well. Since transcranial magnetic stimulation is not feasible after pacemaker implantation, careful assessment is necessary for determining the precise indication for this treatment.
