Abstract: In the case of a 19-year-old man, overuse of his nondominant forearm resulted in a radioulnar synostosis. Despite the persistence of the synostosis, the patient adapted to loss of forearm rotation. No further treatment was necessary. Isolated fractures of the ulnar shaft are slow in healing. Several authors observed that early function may be beneficial. However, excessive activity causing motion at the fracture site may cause subperiosteal hemorrhage and soft tissue trauma and may stimulate exuberant callus formation. Fractures of the ulnar shaft, even undisplaced, need to be immobilized to prevent overuse.

Abstract: The efficacy of tympanometry in the diagnosis of ossicular abnormalities and the differentiation of such from eardrum scarring is controversial. This paper presents a study of the tympanometric effects of specific eardrum scars and ossicular abnormalities in cats. For both normal eardrums and healed myringotomies, a normal middle ear could be differentiated from stapes fixation or incudostapedial discontinuity using static immittance parameters and tympanogram morphology. Twenty percent myringectomy scars caused abnormal 660 Hz tympanograms but this effect could be distinguished from changes caused by a concomitant ossicular abnormality. The very low impedance of a 50% myringectomy scar resulted in tympanograms which could not be differentiated from an ossicular discontinuity alone. With this neomembrane, stapes fixation could not even be differentiated from an ossicular discontinuity. This study supports the view that tympanometry should be interpreted as part of a battery of tests which includes otoscopy, audiometry, and acoustic reflex measurements.

Abstract: CT of compression fractures is a useful adjunct to the plain x-ray in excluding signs of metastasis. However, increased bone density on CT may not distinguish osteoporotic fractures from neoplastic disease, in which case radioiodine scan, bone and marrow biopsies, or myelography may be necessary. Surgery for painful osteoarthritic spinal disease is controversial. The potential advantages of surgery must be weighted against the risk of anesthesia, the length and tolerance of postoperative immobility, and the effect of laminectomy and fusion on the biomechanics of the spine. Furthermore, the elderly are at increased risk for postoperative complications.
