Status of surgical training in the German military.

This article describes the current career path that must be followed when an individual wishes to pursue a career as a surgeon or surgical subspecialist in the German military. After graduating from high school, the young soldier has to sign a 16-year commitment and start medical studies at a civilian university. Having finished medical school, the officer is educated in general medicine for 2 years at one of the military hospitals. Several years as a battalion's doctor complete his or her general training. Basic surgical education of 5 years precedes specialization as trauma/orthopedic, abdominal, vascular, or thoracic surgeon within 3 years. Based on the experiences of the first German attempts in United Nations missions, the education of surgical officers needs to be concentrated on clinical practice. Otherwise, surgical skills cannot be attained and maintained.

Gait pattern analysis after ankle ligament reconstruction (modified Evans procedure).

We followed 38 patients with chronic ankle instability treated by a modified Evans procedure. Evaluation at an average of 68 months follow-up included a standard clinical questionnaire and examination, radiological procedures, and gait analysis. Plantar pressure distribution measurements were recorded during walking and were compared with data from a group of normal subjects (N = 100). The subjective patient questionnaire revealed 87% good or excellent results, but residual pain was reported by 40% of the patients. The gait analysis indicated a significant increase in midfoot loading (22%) consistent with an observed restriction of inversion after surgery. However, the plantar pressure changes were not associated with poor clinical outcome. We cannot say whether these increased pressures will be associated with long-term outcome.

Stress diagnostics of the sprained ankle: evaluation of the anterior drawer test with and without anesthesia.

This study investigated the effect of anesthesia of the peroneal communis nerve on stress diagnostics in acute ankle ligament rupture. Using a special holding device, the anterior drawer sign was measured under loading of 4 to 15 kg with and without a peroneal nerve block. In 65 patients, we found a highly significant difference between these two conditions. In a total of 110 patients, the measurement of anterior drawer sign was correlated to other diagnostic procedures. Absolute values of mechanical anterior drawer sign had a correlation of 0.479, whereas the difference of the measurements in injured and noninjured feet correlated with 0.582. We suggest anesthesia in stress diagnostics to increase accuracy. The anterior drawer sign alone, even under anesthesia, is not reliable to detect the full extent of the ligament damage.

[Light and scanning electron microscopy studies of the pleura. A contribution to the pathogenesis of spontaneous pneumothorax in young patients].

In a prospective study of 10 patients (7 men, 3 women, mean age 26.2 years), who underwent thoracotomy because of recurrent spontaneous pneumothorax, we performed light and scanning electron microscopic investigations of the resected pleura. The purpose of our work was to explain pleural changes which allowed the penetration of air through the intact wall of the blebs. In 8 of 10 cases we found small bullae at the top of the upper lobe, the remaining 2 showed up with massive pleural scar. The morphological and ultrastructural findings indicated that the presence of air induced a reactive process at the visceral pleura which led to degeneration and scarification. The changes consisted of simple membrane formation up to complete destruction of the pleural layer. The development of blebs is due to an air fistula coming out of the lung parenchyma. Penetration of air through the bleb's wall is explained with the increasing pressure inside and the dehiscence of degenerated pleural structure. In our opinion spontaneous pneumothorax in young people is caused by a localized disease of the upper lobe. The pleural changes are the visible effects of a degenerative process induced by air fistula from lung parenchyma. Therefore wedge-resection of that region is a rational therapy in patients with spontaneous pneumothorax.

[Recurrence of non-small cell bronchial cancer: indications and results of surgical treatment].

Bronchoscopic laser application and radiotherapy are very effective in treating the recurrence of bronchogenic carcinoma. Reoperation is rarely possible. During the period from January 1981 to June 1989, 242 patients underwent lung resection at the Bundeswehrhospital Ulm because of malignant airway disease. In ten of these patients reoperation was performed in case of tumour recurrence. The median survival time was 17 months (2 to 60 months). Comparing the literature with our own experience we conclude that operative treatment of bronchogenic recurrences is possible in few selected cases. The indication for reoperation depends on the stage of the primary tumour, the spread of the recurrence and the physiological status of the patient.

[Pleural porosity in idiopathic spontaneous pneumothorax].

Intraoperative investigations after axillary thoracotomy in 28 patients with spontaneous pneumothorax shows true ruptures of subpleural bullae in 25% of the cases. In 75% structural pleural changes in the top of the lung are responsible for porosity and air leakage of the wall of the bullae. Pleural porosity causes a prolonged treatment of this illness. Appreciation of the phenomenon of "pleural porosity" is the key for understanding several questions regarding the diagnosis and treatment of spontaneous pneumothorax that had remained unanswered to date.

[Measuring compartment pressure of the lower leg with a microtip probe].

In the acute compartment syndrome it is difficult to decide on the basis of clinical criteria alone whether or not fasciotomy is indicated. Reliable and objective parameters are required before a treatment schedule can be devised. Measurement of the pressure inside the acute compartment can facilitate the decision as to whether operative treatment is appropriate in the case of the muscular compartment involved. We performed compartment pressure measurements in the tibialis anterior compartment in 27 healthy volunteers using a microtip probe. Clinically relevant results were obtained. It was demonstrated that this method could be used either in acute cases or for long-time measurements. We think that using a microtip probe for intracompartmental pressure measurement provides reliable data and makes the decision on fasciotomy much easier.

[A method for on-line acquisition and semi-automated reporting of unilateral clearance studies of the kidneys (author's transl)].

A four-channel scintillation counter for clearance studies has been connected on-line to a computer. A program has been written which allows the computer to calculate the total clearance rate and the relative contribution of each kidney. The results, together with a semi-automated report, are issued as a letter by teletype. The accuracy of the program has been checked by manual evaluation of the clearance curves.
