[Value of the radiologic Lachman test in evaluating long-term results of operations on the anterior cruciate ligament].

A retrospective study including a 5-years follow-up of 114 patients, that had been operated because of a lesion of the anterior cruciate ligament, used the parameters of the IKDC-score, in 110 cases a radiological Lachman-test was performed simultaneously. A comparison of patient's subjective estimate, of clinical testings, using the pivot shift-test and measurement of anterior instability with the KT-1000 knee arthrometer, and of radiological Lachman-test shows correlations between the 3 first parameters with mostly good results, but poor results in radiological Lachman-test. Mistakes in using the KT-1000 arthrometer may be a reason for this, or a much higher sensitivity of the radiological method, which seems to make it problematic analyzing the radiological measures within the same limits as the arthrometric measures especially in view of demanded scaling scores.

[Results of treatment of humerus shaft fractures].

"It is common practice to treat shaft fractures of the humerus conservatively" says the relevant literature. The results of 126 humerus shaft fractures in the years 1980 to 1989 are reported: 28 fractures were treated conservatively, 98 fractures underwent surgery using plate fixation, mainly the broad AO/ASIF-4,5-mm-DCP. As complications following operative treatment 4 temporary palsies of the radial nerve (4%), three cases of infection (3%) and one non-union (1%) were observed.

[Manometric study on the effect of Hedenstedt's selective proximal vagotomy on the lower esophageal sphincter].

A manometric examination of the oesophagus was carried out before and after selective proximal vagotomy according to Hedenstedt in 20 patients in whom operations were performed at the Dept. of Surgery of the Steglitz Medical Center within the period from 1980 to 1982. The resting pressure of the lower oesophageal sphincter could be shown to be unaltered postoperatively (preoperative median 17,5 mm Hg, postoperative 18 mm Hg, p greater than 0,1 non-significant).

[Stress tolerance of the patient in abdominal surgery: stomach cancer].

Patients with gastric cancer undergoing surgery have much to endure and are accompanied by many risks. These risks depend on localization and extent of the tumor, the patients' general condition (nutritional and immune status), age, coexistent diseases and the extent of the required operation. In view of these facts, the principle of radical surgery must be weighed against the tolerance capability of the patient, especially in old people.
