[Computer tomography in the diagnosis and classification of retrocaval ureters].

A retrocaval ureter is an infrequent congenital defect. Its diagnosis depends on radiodiagnostic methods. Some may be replaced by computed tomography computed tomography.

[Results of replantation in thumb amputations. New examination methods for evaluation of sensation].

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.

[Experiences in the use of pedicled muscle flaps in reconstructive accident surgery].

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.

[Reconstruction of combined soft tissue and bone defects of the lower leg].

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.

[Treatment of fresh and old ruptures of the extensor tendons (author's transl)].

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.
