107 of 604 cases with scaphoid non-union had secondary arthrosis of the wrist before surgical treatment by the Matti-Russe technique. In contrast to earlier opinions the results of this retrospective study show that this procedure is indicated more frequently.

The authors report on their experience on 176 patients with lesions of the ulnar collateral ligaments. Two samples were compared: the fresh rupture and immediate suture, and the old lesion treated by a special plasty with palmaris tendon (Bäuerle/Reill). The long term results (at least 2 years) of both collectives were nearly identical. The authors recommend immediate repair.

Staged flexor tendon repair utilizing temporary silastic rod implants has proved to be an effective method for restoring the grip function of severely injuried hands. Since its inauguration by CARROLL and BASSETT in 1958 this method has been successfully practiced by numerous hand surgeons. In this review the patho-physiological principles of the development of the so-called "pseudo tendon sheath" are described. The various findings as far as the formation of the new tendon sheath is concerned, are presented. The theories about incorporation of the subsequent graft and its revascularization are described. Following a detailed description of the surgical procedure our own results with 272 silastic rod implants in 184 patients are presented. Because of the kind of patients selected for the procedure, excellent results were not obtained. However, in 62% of cases results were graded "good" and in 23%, "satisfactory", while 15% were "poor". It seems to be justified to utilize two-stage flexor tendon repair for restoring grip function in severely injured hands in spite of the considerably high technical requirements, the prolonged course of rehabilitation and consequently increased cost of treatment.
Nerve section is followed by a reduction of motor and sensory conduction velocity in the proximal segment of the injured nerve. This reduction of velocity is associated with retrograde changes in fiber size. If reinnervation does not occur within the next 1 1/2--2 years, retrograde degeneration of nerve fibers results, and the amplitude of the evoked nerve potential in the proximal segment of the injured nerve decreases. This retrograde degeneration is probably significant in view of the poor results frequently obtained after nerve transplantation which is carried out too late.

Regarding experimental data on the multi-factorial reduction of the thermostability of collagen, the following sequence of the mechanism of Dupuytren's contracture is discussed: 1. Hereditary or acquired weakness of fibres of the palmar fascia 2. Further disturbance of the physical property of collagen by the cumulative effects of mechanical, i.e. traumatic, influence. 3. By this means an induced stepwise shrinkage of released fascial fibres in body temperature. 4. Stabilisation of the shortening (contracture) by development of collagen. This hypothesis is supported by histological, polarizing-microscopic, electron-microscopic and chemical results.
The authors report on their experience on 20 old lesions of the ulnar collateral ligament of the MP joint of the thumb. They used a modified technique according to Strandell.--Follow up investigations were made in an average range of 17.5 months after the operation. All the colateral ligaments were stable. The procedure is not to be used for heavy manual working persons. If there is an osteoarthritis in the MP joint, arthrodesis is the alternative method.

We investigated 59 patients in later stages after section and suture (n =23) or transplantation (n = 36) of the ulnar or median nerve. The most typical change in electromyographic pattern consists in a markedly increase of mean amplitude, due to an increased number and concentration of muslce fibers in the reconstituted motor-units. The mean duration and the incidence of polyphasic potentials are only slightly increased, indicating a nearly synchronous excitement of the different muscle fibers of the various motor-units. In no case there is a complete recovery; the mean amplitude of evoked potentials in reinnervated muscles varied from 32% in poor-, to 62% in satisfactory reinnervation, compared with the corresponding normal muscle in the opposite hand.

When treated conservatively, fractures of the proximal and middle phalanges require long immobilization with results usually being poor. Operative treatment with K-wires has also been found not to be entirely satisfactory. Therefore small screws and plates (AO) were developed for internal fixation and used in 31 phalangeal fractures. The technique and instruments used are described. Functional results appeared to be superior with this method reported here.
