Sixty-eight patients born with a myelomeningocele were studied in the second and third decades of their lives. All of them had had some orthopaedic surgery, an orthotic program, and other specialized medical and paramedical services. In the group with sacral-level lesions, half were community ambulators; in the group with lower lumbar lesions, a third; in the group with upper lumbar lesions, a tenth; and in the group with thoracic-level lesions, none. The most important factors that determine the ambulatory status of a child with myelomeningocele, besides the level of the lesion, are the motor power within a given neurosegmental level and the extent and degree of orthopaedic deformities.

Computed tomography (CT) was performed within 4-8 days of injury in three patients with five fractures of the calcaneus. Three of the fractures were comminuted, and CT gave graphic additional information to the plain radiographs. Three fractures were undisplaced and were managed conservatively. In the other two, there was displacement of bony fragments, and these were treated operatively. In these, CT gave valuable preoperative information regarding the size and location of fracture fragments and helped the surgeon determine the site of incision and type of surgery required. The CT findings were confirmed at operation. CT therefore provides useful information for the management of these difficult fractures.
We have evaluated a new, hand-held, electronic device to measure maximal respiratory pressures, and compared its performance in normal subjects against two pre-existing methods. This new device produces accurate, reproducible results and has the advantages of easy use and portability, which allow it to be used at the patient's bedside, outpatient clinic or pulmonary function laboratory.
