Prognostic aspects in operated ankle fractures.

A long-term follow-up (3.5 years mean) of 106 operated ankle fractures out of 167 patients revealed 73.7% excellent and good, 16% acceptable and 10.3% poor results. Anatomically exact reduction was shown to be a prerequisite for good results and was seen in 77.2% of all cases. By neglecting biomechanical principles an insufficient reconstruction led to a poor final outcome. But even in 11% of the excellent operatively treated fractures late arthrosis developed. Statistical analysis showed that the onset of posttraumatic arthrosis was correlated with and predicted best by the number of single lesions. Dorsiflexion testing was the clinical parameter correlating best with the extent of the injury, the degree of arthrosis and the subjective complaints. This underlines the importance of assessment of dorsiflexion as a clinical screening test for remaining sequelae after ankle fractures.

Long-term radiological and clinical observations following surgery for tibio-fibular syndesmosis after fractures of the upper ankle joint (author's transl)

Forty-two patients treated surgically for tibio-fibular syndesmosis were observed radiologically and clinically for a period of five years; the lesions followed fracture-dislocations type B, type C and following intra-articular fractures. Surgery consisted, as usual, of bone reconstruction and, where necessary, of transfixation of the syndesmosis with a horizontal screw introduced 2 cm. above the syndesmosis at a 30 degree angle to the frontal plane (15 cases). A new classification of the severity of subsequent arthrosis, as seen radiologically, was introduced and its correlation with clinical findings were determined. There was good agreement between the degree of arthrosis and functional results. The earliest signs of posttraumatic arthrosis following an incompletely treated lesion can be seen within the first year following the injury. An arthrosis of severity O due to sclerosis is of no, or only little, significance; it does not share the poor prognosis of severity grades I to III which, once they have developed, always show further deterioration.

Microradiographic study of human temporomandibular disks obtained at autopsy.

Abstract. Ninety‐six temporomandibular joint disks obtained at autopsy from subjects aged 1 day to 93 years of age and divided into three groups according to dental status were examined micro‐radiographically for calcification.The central part of the disks showed no calcifications in individuals less than 30 years old, and only a few in persons above 30 years with a good denial status, while the occurrence was much greater in patients who had lost many or all of their teeth. In the peripheral part of the disk there were occasional calcifications already in children, and in elderly individuals the calcifications were more common, but the frequency did not appear to vary with the number of residual natural teeth or with the degree of arthrosis of the temporomandibular joint.
