Operative treatment of the chronic post-traumatic boutonnière deformity by the technique of pieper.

We report eleven cases of chronic, non-fixed, post-traumatic boutonnière deformity treated by the technique of Pieper: One lateral slip was mobilised and distally desinserted. At the PIP, the slip was pulled through the central slip and sutured in correct tension to the released opposite lateral slip. 73 % regained full extension at the proximal interphalangeal joint.

[Defect coverage with a bilobed flap with reference to special aspects regarding the nose].

Defects at the dorsum or tip of the nose are a special challenge for plastic surgeons. Considering the tough skin, primary closure is normally not possible. As full-thickness skin grafts are not satisfactory, we strive for defect-coverage using adjacent skin.

[Closed extensor tendon injuries of the finger].

The extensor apparatus of the fingers is a complex structure. The diagram of the extensor apparatus as seen in figure 1 is in reality not so clearly structured. Closed lesions are the mallet finger, where either an avulsion of the bony insertion of the tendon occurs or where a fracture of the base of the distal phalanx with dislocation of a bone-fragment together with the tendon insertion has happened.

Contour correction of the vermilion of the upper lip by island flap of the lower lip.

A method is shown to correct contour defects of the upper lip vermilion by an island of vermilion of the lower lip. A muscle bundle of the orbicularis oris is used to carry the island. It is tunneled around the commissure to the upper lip defect.

[10 years results following augmentation-plasty].

In order to investigate late results in cases with mamma-augmentations, we have controlled cases which have been operated between 1970 and 1980. From a total number of 70 cases 34 have appeared for control. In spite of the problems of capsular contracture the interest for mamma-augmentation has rather increased during this period of time.
