[Computer tomography in the diagnosis and classification of retrocaval ureters]. / Príspevek výpocetní tomografie k diagnostice a klasifikaci retrokaválního mocovodu.

A retrocaval ureter is an infrequent congenital defect. Its diagnosis depends on radiodiagnostic methods. Some may be replaced by computed tomography computed tomography. They submit the classification of retrocaval ureters elaborated by Kenawi-Williams.

[Results of replantation in thumb amputations. New examination methods for evaluation of sensation]. / Replantationsergebnisse von Daumenamputationen. Neue Untersuchungsmethoden zur Sensibilitätsprüfung.

Of 91 thumb amputation injuries which were treated over a five-year period at the Department of Traumatology, University School of Surgery Homburg/Saar, 56% could be subjected to a critical follow-up evaluation. The evaluation scheme of Millesi "Evaluation and Registration of Hand Function" programmed for electronic data processing forms the basis for the study. Besides the specified criteria for sensitivity testing, a further method for objective testing is presented. The principle of this method is point stimulation of pressure and mechanoreceptors after eliciting a threshold perceptible vibration stimulus of an 80 Hz sinusoidal oscillation the intensity of which can be directly measured as a yardstick for the stimulus response. Electronic processing of all results of the patients investigated shows that the injured hand can be used to almost 100% in 38%. In 16 patients (31%), there is a reduction by 5 to 20%. In ten cases (20%), the reduction was rated as over 20% compared to a healthy hand and in 11% (six patients), the overall result is to be designated as poor with more than 40% reduction of use.

[Experiences in the use of pedicled muscle flaps in reconstructive accident surgery]. / Erfahrungen bei der Anwendung gestielter Muskellappen in der rekonstruktiven Unfallchirurgie.

The one year-experience with muscle and musculocutaneous flaps in 16 patients with 18 flaps in different regions of the body is represented. The indications were open fractures with extensive loss of soft tissue, infectious complications after joint-replacement or osteomyelitis, defects after tumor resection or irradiation therapy and decubital ulcers. In 11 patients there was a satisfactory result. Complications with partial loss of the flap resulted from primary transposition in open fractures with marked contusion of the muscle, neglection of the specific vascularisation pattern or irradical necrectomy. Viewing the relatively simple operative techniques with muscle and musculocutaneous transposition or island flaps, free microvascular tissue transfer may be unnecessary in many situations.

[Reconstruction of combined soft tissue and bone defects of the lower leg]. / Wiederherstellung bei kombinierten Weichteil- und Knochendefekten des Unterschenkels.

In 7 patients with traumatic defects of the soft parts and bone of the lower leg the authors transplanted a free latissimus dorsi flap with microvascular connection. The surgical technique and approach are described. Secondary autologous spongioplasty. The results are stated. The method is a safe one.

[Treatment of fresh and old ruptures of the extensor tendons (author's transl)]. / Die Behandlung der frischen und alten Strecksehnenrupturen.

Knowledge of topographical anatomy and physiological interplay of several structures is considered essential for regaining the normal function of the extensor apparatus of the finger after an acute or an old injury. For better comprehension of the extensor apparatus and because of its anatomical and functional complexity, two types of structural systems are described, namely, the tendinous and the retinacular system. Aetiological aspects and the pathophysiological mechanisms of deformities such as the "swan-neck deformity, boutonnière deformity and mallet finger" are also described and possibilities of surgical treatment are discussed. Rare injuries such as laceration of the extensor pollicis longus tendon or laceration of the metacarpophalangeal extensor hood with a consecutive radial or ulnar shift of the long extensor tendon are also described and mentioned with possible surgical treatment methods.
