Some additional suggestions for an intervertebral disc prosthesis.

The paper, which refers to previous original papers on the subject, gives suggestions indicating four intervertebral disc prostheses, one utilizing bone cement for fixation to the bony substance of the motion segment. In the paper a modification of this inter-vertebral disc prosthesis offers a possibility for fixation of the prosthesis by osteointegration.

Compression and the osteotomy gap.

The existence of a clearly visible osteotomy gap by optimal roentgenography even in cases where high compression had been applied is exemplified. One case of fracture of the osteosynthesis material used in a medial displacement osteotomy is illustrated. It is suggested that this and similar accidents are sometimes consequences of imperfect surface contact at the operation, visible only by central beam radiography.

Open reduction of central compression fractures of the tibial plateau. Preliminary report of a new method and device arrangement.

A new method of reduction and fixation of a uniformly depressed fracture of the tibial condyle is described. A curved steel probe, introduced through a cortical window in the uninjured condyle, is used to reduce the fracture fragments as well as to compact the fracture region (TV-monitored x-ray projectioning is desired). The instruments needed for the operative procedure are as follows: a probe for reduction and compaction, a tube and a plunger for deposition of bone transplants, and a forked plate. Five cases in which the curved probe reduction method has been used are reported.

Fracture of the scapular notch associated with lesion of the suprascapular nerve.

In a material consisting of 18 patients with scapula fractures, the scapular notch was involved in two cases. In one of these cases injury of the suprascapular nerve function was proved. The value of X-ray examination with projections visualizing the scapular notch is pointed out. EMG examination in selected cases with the combination of reduced supraspinatus muscle function and a fracture of the scapular notch is recommended in order to diagnose injury of the suprascapular nerve.

End result observations of X plate compression fixation. A critical review and analysis and a discussion of unsolved problems.

The X plate method of treatment of a diaphyseal fracture employs te internal, cortical and extramedullary compression-fixation of a shaft fracture, using a steel plate device of two components. Four wedges of the X device force the surfaces of the fracture against each other at the same time as the plate is pressed against the cortical surfaces of the reduced fracture fragments. The two components of the device are finally made to interlock firmly. Screws are not used. Plate onlay force and fracture compression force are created by the purchasing of the wedges against the rims of exactly predrilled cortical bores of the fracture fragments. A drill guide, and a device that permits pre-compression and temporary fixation of the fracture fragments are used when drilling is performed. Successvie designs of the employed X devices and auxiliary instruments are described. Clinical experience of the method so far has been satisfactory. Twenty-six forearm shaft fractures and two osteotomies of malunited shaft fractures have been successfuly treated. Present problems are related to the possible need of an implant material of a more springy character tan that of the 2353 (316L) steel implant, used at present and also to reduce the manufacturing costs.
