[Compression of the ulnar nerve at the wrist (author's transl)].

Compressions of the ulnar nerve at the wrist in or beyond the canal de Guyon are comparative rare. Those originating from compression in the sulcus ulnaris at the elbow are much more common. The clinical symptoms are typical: Weakness of the small muscles of the hand, loss of sensibility and pain. The diagnosis can be made on the clinical picture. It has to be confirmed by electromyography. Surgery should be performed as early as possible to avoid permanent damage to the nerve. Any delay can cause irreversible loss of function of the ulnar nerve. As causes of the compression of the ulnar nerve tumours, inflammation of the sourrounding tissue or trauma have been described. In this paper we report about compression of the ulnar nerve in the canal de Guyon due to a thrombosed aneurysme of the ulnar artery. This condition is quite rare. It is characterized through sudden onset of pain in the hand. Immediate surgery with decompression of the nerve, as we did in our case, will result in complete recovery.

[The prevention and treatment of post-operative and post-traumatic oedema. Chemical laboratory tests on the renal tolerance of beta-aescin (reparil) (author's transl)].

Renal tolerance of the preparation beta-aescin (Reparil) was tested in cases of oedema following fresh soft tissue crush injuries of the extremities and surgical and reconstructive operations on the hand. Forty in-patients with healthy kidneys were treated with 10 mg beta-aescin intravenously twice daily for six days after operations on the hand and after accident surgery. During this period the following tests were carried out every day and two days after cessation of treatment: urea content in urine and serum, creatinine in serum, creatinine clearance, albumin in urine, urine osmolarity and blood and urine sugar. All values obtained were within the normal range. No impairment of total renal function was observed. Taking the stated dosage instructions and contra-indications into consideration, beta-aescin can thus be administered without hesitation.

[The tendon interposition plastic with partly necrosised scaphoid pseudarthrosis (author's transl)].

We have seen in 4 cases of 46 operated scaphoid pseudarthrosis aseptic bone necrosis of a fragment. According to the tendon interposition plastic of Froimson for the substitute arthrose of the saddlepoint of the thumb. We exstirpated the bionecrotic fragment of the scaphoid, splitted the tendon of the flexor carpi radialis muscle, removed a part of the tendon from the belly of the muscle, rolled it in and fixed it in the excavated cavity of the bone. After an observation time of 6 months to 1.5 years all 4 patients have not developed complications.

[Unusual genesis of a carpal tunnel syndrome].

The genesis of a carpal tunnel syndrome not described before is reported. The case in question is a 45-year-old patient with a four weeks history and increasing complaints (pain on motion and at rest, positive Hoffmann-Tinel's sign, positive extension and flexion test, considerable delay in the speed of nerve conduction). During the operation a thrombosed epineural vessel was found. Histologically, it could not be stated with certainty whether this had been a thrombosed artery or vein.

[New results on the genesis of traumatic Achilles tendon rupture].

As a result of the development of a new fixing mechanism, which permitted the test of peak value of tensile strength in Achilles tendons, the following facts were demonstrated: 1. The average value of static maximum of tensile strength is about 7, 5 kp/mm2, of the dynamic maximum is about 10, 1 kp/mm2. 2. The charge maximum decreases with progressive age. 3. The tensile strength depends on the minimal cross-section plane of the tendon. 4. The minimal cross section plane decreases with progressive age. 5. With the test of dynamic tensile strength it is possible to malinger a Achilles tendon rupture.
