[Diagnosis of compartment syndrome].

Clinical diagnosis remains the most important factor in the diagnosis of compartment syndrome. Parameters such as swelling, pain result from passive stretching, sensory disturbances, motor weakness and pulse rate should be carefully analysed and recorded using a checklist. As a compartment syndrome can already occur after 2 h but often not until 6 days later, monitoring at short intervals is necessary during this time period. If the clinical diagnosis is not clear-cut and the possibilities of differential diagnosis have been exhausted, or if there is doubt concerning the extent of the increase in pressure, pressure should be measured to help establish the diagnosis.

[Ultrasound diagnosis of pathologic changes of the anterior knee joint. Value, indications, case reports].

Ultrasonography (7.5 MHz linear scan) was employed in 129 patients with pathologic conditions of the front parts of the knee and its value was compared with other imaging modalities (x-ray, CT). Surgical or arthroscopic correlation was available in 75 patients (43 with injuries, 32 non-traumatic). In view of its high sensitivity and positive predictive value we suggest the use of sonography in these applications: 1. Differential diagnosis of periarticular swellings 2. Lesions of the knee extensor mechanism 3. Documentation of stability tests 4. Lesions of the intercondylar cartilage 5. Follow-up of therapy effects On account of the low sensitivity we do not recommend regular sonographic examination of menisci with linear scans.

[Sonographic follow-up of secondary fracture healing. Initial experiences with morphologic and semiquantitative assessment of periosteal callus formation].

We report on the contribution of real-time sonography in comparison to plain radiographs to the assessment of fracture healing of 121 patients suffering fractures of the long bones of the lower limbs. Sonographic morphology of periosteal callus metamorphosis shows basically a persistent increase of echogenicity representing the temporal range from fracture haematoma to the "woven bone". Further criteria are the homogeneity of structure and the development of a marginal interface. Nonunion radiologically classified into hypertrophic and atrophic types may also be differentiated by sonographic criteria and may influence proper orthopaedic management. Regarding sonographic methods using an A-mode amplitude signal, the morphologic assessment of callus metamorphosis is more likely to be translated into clinical practice. Although it yields a variety of information, sonography will be unable to replace radiography due to methodical limitations.

[Bilateral gallbladder rupture after blunt abdominal trauma].

A 65-year-old man under the influence of alcohol sustained blunt trauma to the abdomen in an accident while riding a motorcycle. An intramural haematoma of the gall-bladder was demonstrated by computed tomography: peritoneal lavage was negative. About five hours later the gall-bladder ruptured, as confirmed at laparotomy. The postoperative course after cholecystectomy was uneventful.

[High resolution real time sonography in sports specific muscle injuries. Sonomorphologic-anatomic correlation and diagnostic criteria].

In 250 examinations of 86 patients, high resolution real time sonography with a 7.5 MHz linear transducer proved to be a readily available, low-cost and significantly relevant imaging method in diagnosis and follow-up of muscular lesions in sportsmen. The method offers a high measure of safety in excluding rupture or in enabling differential diagnosis between partial muscular rupture and muscular spasm, so that the choice of treatment can be decisively influenced by sonography. Hence, rapid rehabilitation, which is so essential in competitive sport, is speeded up even further. In extensive ruptures or rupture haematoma, therapeutic ultrasound-guided puncture can be performed or indication for surgery can be facilitated in subtotal or complete tears of a muscle that is important for high-level performance.

Eighty-five talus fractures treated by ORIF with five to eight years of follow-up study of 69 patients.

Four types of talus fractures can be distinguished and the prognosis predicted on the basis of vascular patterns before and after injury. Early decompression of the soft tissues or anatomic reduction by closed or (if not possible) open methods is indicated. Stable fixation by lag screws and functional aftertreatment help to improve the prognosis. The late results with reference to necrosis, posttraumatic arthrosis, secondary arthrodesis, and functional outcome show that open reduction and internal fixation, applied early, can produce better functions than was heretofore thought possible. Special emphasis is placed on careful indications, operative techniques, and postoperative treatment--particularly the time of partial weight-bearing with a caliper brace.

Results of AO plate fixation of forearm shaft fractures in adults.

A series of 111 forearm fractures in 108 individuals involving 177 individual bones, and treated by AO plating is reported. There were 18 different surgeons. Open fractures occurred in 24 per cent of limbs. Reviews at a mean of 3 years after the accident showed 97 per cent of bones to be solidly united, and satisfactory function to be achieved in 80 per cent of limbs. Deep infection occurred 6 times, and non-union in 7 bones. Cross-union developed in 6 patients, all of whom had sustained head injuries. Seven patients sustained operative nerve injuries. It is felt that the implant of choice at the moment is the small fragment Dynamic Compression Plate (DCP).

[Etiology, pathophysiology and anatomical location of the compartment syndrome].

Tissue pressure elevation may be caused by diminution of the compartment (operative closure of fascial defects, the presence of tight bandages or air-splints or by prolonged localized external pressure, as in unconscious patients), and/or by an increase in its contents (hemorrhage or the various conditions causing increased capillary permeability, e.g. postischemic swelling, fractures, surgical orthopedic procedures) or increased capillary pressure, e.g. after exercises. Additional elevation of an injured limb may cause a compartmental syndrome by lowering capillary pressure, especially in shock patients.

Injuries to the tarsometatarsal joint. Incidence, classification and treatment.

Injuries to the tarsometatarsal (Lisfranc) joint are not common, and the results of treatment are often unsatisfactory. Since no individual is likely to see many such injuries, we decided to make a retrospective study of patients from five different centres. In this way 119 patients with injuries of the Lisfranc joint have been collected. This paper classifies these injuries and describes their incidence, mechanism of production, methods of treatment, results and complications. Sixty-nine of the patients attended for review: 35 of these had been treated by closed methods, 27 had had an open reduction and seven patients had had no treatment. On the basis of our study we suggest that these injuries should be classified according to the type of injury rather than the nature of the deforming force and that their treatment be based upon this classification. It seems that, whatever the severity of the initial injury, prognosis depends on accurate reduction and its maintenance.

[Diagnostic value of osteoscintigraphy and osteoscintimetry for assessment of post-traumatic osteomyelitis and of its complications (author's transl)].

The importance of osteoscintigraphy and osteoscintimetry for diagnosis and case control in post-traumatic osteomyelitis and its complications is discussed by means of 182 bone scintigraphs. Scintigraphy as a functional examination enables clear statements on the probable future course of development of an infection of the bone, of a sequestrum, on the vitality of bone fragments, and on the probable course of infected psuedarthroses and spongiosa transplants.
