*A paper read at the South African Medical Congress, Johannesburg, September 1952. 1. The effect of torque on the causation of lumbar disc herniations is discussed. 2. Attention is drawn to the range of rotation that exists in the lumbar spine. 3. Traumatic torque is elucidated and two signs for the recognition of its direction are descriptionbed. 4. A method of conservative and ambulant treatment known as ' counter-torque suspension ' is descriptionbed. 5. A traction table embodying these principles is descriptionbed.
Two hundred unselected cases of appendicectomy are analysed with regard to age groups, sex, racial incidence and the preoperative and histological diagnoses. A high percentage of these cases was found to have normal appendices histologically. It is stressed that full investigation in cases of suspected acute or chronic appendicitis is essential before operating, but that even then the correct preoperative diagnosis may be extremely difficult and in many cases the symptomatology remains unexplained.
