[Effectiveness of an improved antiseptic in treatment of contaminated soft tissue wounds].

A novel antiseptic biguanide has been shown to be more bactericidal and tissue compatible in vitro than other antiseptics. In our controlled, prospective and randomized double-blind study on patients with bacteria-contaminated wound types 2-4, one group (n = 45) was treated with humid cotton swab dressings of 0.2% Lavasept solution compared with Ringer solution (n = 35). No deterioration of wound healing was observed in either group. Lavasept treatment resulted in faster and significant reduction of gram-positive germs. The tissue compatibility of Lavasept was evaluated as significantly better than Ringer solution.

Results of flexor tendon repair of the hand by the motion-stable wire suture by Towfigh.

We compared the motion-stable wire suture by Towfigh (MSWST) with a modified Kessler suture (MKS) by following up flexor tendon repairs (MSWST, n = 21/39 digits; MKS, n = 20/31 digits). For MSWST we found 31 (79.5%) "excellent", 3 (7.7%) "good", and 5 (12.8%) "fair" results, when using the scoring system of Buck-Gramcko. In 3 (14.3%) patients the MSWST had to be removed owing to local irritation. In a further 3 (14.3%) patients, this was done when secondary tenolysis was necessary. The latter was also performed in 4 (20.0%) patients in whom the MKS was used. Here we found 23 (74.2%) excellent, 7 (22.6%) good, and 1 (3.2%) fair result. The statistical evaluation of the data concerning the patients' age, sex, the involved zone, the side, and the functional outcome did not reveal a significant difference (P < 0.05) between both groups and the chosen type of repair. The results of MSWST and MKS are similar, but MSWST allows early motion therapy without a splint or rubber-band protection.

[Mechanical stimulation of venous blood flow in below-the-knee plaster cast].

Physical methods became recently more important as an alternative to anticoagulation for prophylaxis of thromboembolism and were studied for their efficacy. The AV-impulse-system proved efficient in reducing thromboembolic complications in patients undergoing hip surgery by increasing the return of venous blood in the deep veins of the leg. In a preclinical trial we studied the influence of the AV-impulse-system and of active forefoot movement on venous blood return in 12 lower extremities of 6 healthy individuals immobilized in below the knee plaster casts. Our results show a significant increase in venous blood flow caused by the AV-impulse-system (p < 0.05) and by active forefoot movements (p < 0.05). Prevention of thromboembolic complications in trauma and orthopaedic patients immobilized in plaster cast seems possible by using the AV-impulse-system which significantly increases the venous blood flow independent from patient compliance.

Grading of functional results of elbow joint arthrolysis after fracture treatment.

In the treatment of posttraumatic contracture of the elbow joint, arthrolysis is a proven procedure. We used a stepwise operative approach starting laterally and including an additional medial and dorsal incision if needed. A total of 91 patients with arthrolysis of the elbow could be followed-up on average 44 months (range 9-102 months) joint after operative (58, 63.7%) and non-operative (33, 36.3%) fracture treatment. The mean preoperative range of motion (ROM) in flexion/extension was 49 degrees (SD +/- 38 degrees), while in pronation/supination it was 89 degrees (SD +/- 66 degrees). Postoperatively, the ROM was on average 94 degrees (SD +/- 27 degrees) in flexion/extension and 129 degrees (SD +/- 52 degrees) in pronation/supination. Using our own grading system, it became evident that most patients had a functional benefit from the procedure, although the quality of the improvement differed. For example, postoperatively 59.3% of the patients were grade I (> or = 90 degrees) in flexion/extension compared with 16.5% preoperatively. Although the rest also showed improvements, their functional benefit was less. The earlier the release of the joints was performed, the better was the functional outcome (p < 0.05). The importance of an intensive early rehabilitation programme is emphasised while indications for this procedure should only be seen in compliant patients.

Tikhoff-Linberg procedure for bone and soft tissue tumors of the shoulder girdle.

OBJECTIVE: To evaluate complications and the oncological and intermediate-term functional results in patients with bone and soft tissue tumors of the shoulder girdle who were managed with interscapulothoracic resection (Tikhoff-Linberg procedure). DESIGN: Case series of 19 consecutive patients during a 10-year period at a mean follow-up of 6.3 years (range, 1-11 years). SETTING: University hospital; referral center for musculoskeletal tumor surgery. PATIENTS: The initial diagnosis in this consecutive series of patients with shoulder girdle tumors requiring the Tikhoff-Linberg procedure was chondrosarcoma in 7 patients, Ewing sarcoma in 3 patients, malignant fibrous histiocytoma in 3 patients, solitary metastasis of thyroid carcinoma in 2 patients, osteosarcoma, synovial sarcoma, angiosarcoma, ancd neurofibrosarcoma in 1 patient each. According to the Musculoskeletal Tumor Society staging system, there were 6 in surgical stage IB, 10 in stage IIB, and 3 in stage III. Nine tumors involved the proximal humerus, 8 were located in the scapula or surrounding soft tissues, 1 in the lateral clavicle, and 1 in the acromioclavicular joint. INTERVENTIONS: For reconstruction of the proximal humerus after en bloc tumor resection an isoelastic cemented shoulder tumor prosthesis was inserted in every patient to restore arm length. MAIN OUTCOME MEASURES: Complications, and oncological and intermediate-term functional results. RESULTS: Twelve patients were alive with no evidence of disease. One of these patients died of nontumorous disease 2 years after surgery. One patient is alive with pulmonary metastases after 12 months. Six patients died of metastases at a mean (SD) interval of 18 months (range, 3-35 months) postoperatively. Two of these patients had additional local recurrence. A deep infection necessitated the explantation of the prosthesis in 1 patient. The mean functional score and SD according to the rating system of the Musculoskeletal Tumor Society was 72%+/-14% (range, 33%-87%) for the 12 surviving patients evaluated. Major complications (1 infection and 2 local recurrences) that may be attributed to the procedure occurred in 3 of the 19 patients. CONCLUSION: Despite an overall complication rate of 74% the Tikhoff-Linberg procedure proved to be a valuable surgical procedure for extended tumors of the shoulder girdle for functional and oncological outcome and is superior to forequarter amputation.

[Injuries due to falls from a great height. A comparative analysis of injuries and their outcome following suicide-related and accidental falls].

The aim of this study was to compare the outcome and clinical course of multiple trauma patients with accidental or intentional (suicide related) fall from heights > 4 m. 211 patients with an injury severity score (ISS) > 17 were assigned to the following groups: I: intentional fall, n = 94; A: accidental fall, n = 117) and ISS (I: 28 +/- 1; A: 30 +/- 1), ventilation time (I: 16 +/- 2; A: 15 +/- 1) were not different. Significant differences were found in sex (m/f: I: 56/44; A: 73/27%), fractures of lumbarspine (I: 34; A: 15%), pelvis (I: 51; A: 38%), lower leg (I: 47; A: 20%), pilon (I: 15; A: 5%), and os calcis (I: 17; A: 9%). Liver lacerations occurred more often after intentional fall (I: 16; A: 6%). Single or multiple organ failure (MOF) was diagnosed significantly more often in group A(I: 1; A: 8%). Main cause of death in both groups was single or multiple organ failure (MOF: I: 47; A: 69%) or related to brain-injuries (I: 35; A: 19%). Prognosis and rehabilitation of multiple trauma patients after intentional fall is related to brain-injuries, spine-fractures and the functional outcome of the injured lower leg. Prognosis of patients after accidental fall is related to the development of MOF during the ICU-course.

[Lengemann suture versus bone screw osteosynthesis in treatment of ulnar osseous collateral ligament rupture of the thumb metacarpophalangeal joint].

Out of 95 ligamentous lesions of the thumb metacarpophalangeal joint, those with an isolated bony rupture of the ulnar collateral ligament were chosen. Of these, 15 patients treated with Lengemann suture and 16 with screw fixation were followed-up on average 27.3 and 26.4 months, respectively, after operative treatment. Under only "good" and "very good" clinical results, the statistical analysis of the objective and subjective parameters showed no significant difference, except for the measurement of the soft-tissue circumference (p < 0.01) between either procedure. Although both procedures have a low rate of complications, screw fixation is preferable since implant removal is not necessary.

The extent of traumatic damage determines a graded depression of the endotoxin responsiveness of peripheral blood mononuclear cells from patients with blunt injuries.

OBJECTIVE: To study whether the endotoxin responsiveness of peripheral blood mononuclear cells correlates with the severity of injury in trauma patients. DESIGN: Prospective, observational study. SETTING: University trauma center. PATIENTS: Fifty-nine patients with blunt trauma (Injury Severity Score [ISS] 4 to 57 points). INTERVENTIONS: Standard emergency department care, surgical care, and postoperative intensive care unit treatment. MEASUREMENTS AND MAIN RESULTS: Whole blood and serum were obtained 94+/-89 (SD) mins post trauma (day 0) and during a 14-day period postinjury. Endotoxin-induced tumor necrosis factor-alpha (TNF-alpha) synthesis of peripheral blood mononuclear cells ex vivo was tested using a whole blood assay. Serum samples were assayed for TNF-alpha concentrations. A reduced capacity of whole blood to produce TNF-alpha ex vivo with endotoxin treatment was found to be closely correlated with the ISS. The capacity to produce TNF-alpha on endotoxin stimulation of whole blood from patients with an ISS > or =16 points was depressed immediately after trauma and did not reach normal values during the observation period. In patients with an ISS >22 points, maximum depression of the capacity of whole blood to produce TNF-alpha occurs within 100 mins post injury. In contrast, in patients with an ISS <22 points, maximal depression of whole blood TNF-alpha production occurs with a delay of 24 to 48 hrs after trauma. Based on pre- and postoperative values, primary surgical intervention caused a decrease of the endotoxin-stimulated TNF-alpha production of whole blood in the latter patient subgroup, as well as in the entire patient population (ISS 4 to 57) when secondary surgical treatment was necessary 5 to 13 days after trauma. CONCLUSIONS: The extent of traumatic tissue damage leads to a graded depression of immunocyte function and appears to be amplified by surgical treatment. The endotoxin responsiveness of peripheral blood mononuclear cells displays a functional marker of the anatomically defined severity of injury and gives insights into the regulation of immunocyte function after severe blunt trauma.

Local effect of lung contusion on lung surfactant composition in multiple trauma patients.

OBJECTIVE: The aim of this study was to investigate the direct influence of lung contusion on pulmonary surfactant in multiple trauma patients. DESIGN: Prospective, nonrandomized study. SETTING: University hospital, trauma intensive care unit. PATIENTS: Eighteen multiple trauma patients with unilateral lung contusions and Injury Severity Scores >19 were studied prospectively. INTERVENTIONS: Bronchoalveolar lavage was performed daily until either day 7 or extubation. Samples from the side of lung contusion (n = 62) and the contralateral, uninjured side (n = 62) were obtained at the same time in 14 patients. Total phospholipids, total phospholipid classes, and surfactant apoprotein A were quantified. Additionally, surfactant function was measured with a pulsating bubble surfactometer in four patients. All data are presented as mean +/- SEM. Statistical analyses were performed using programs of SPSS for Windows 6.1.3 (SPSS Inc., Chicago, IL) (Student's t-test; p < .05). MEASUREMENTS AND MAIN RESULTS: Total phospholipids were significantly increased on the side of lung contusion (contusion side, 40+/-7 microg/mL; contralateral side, 21+/-3 microg/mL; p = .004). The percentage contents of phosphatidylcholine (contusion side, 87.1%+/-1.0%; contralateral side, 84.3%+/-1.0%; p = .04) and sphingomyelin (contusion side, 2.9%+/-0.3%; contralateral side, 1.9%+/-0.2%; p = .004) were significantly higher. In contrast, the percentage content of phosphatidylglycerol was significantly decreased (contusion side, 4.1%+/-0.1%; contralateral side, 6.9%+/-0.6%; p = .001). No alterations were found for the relative contents of phosphatidylethanolamine (contusion side, 2.4%+/-0.2%; contralateral side, 2.2%+/-0.2%; p = .47), phosphatidylinositol (contusion side, 3.5%+/-0.4%; contralateral side, 4.6%+/-0.5%; p = .06), and surfactant apoprotein A (contusion side, 7177+/-1404 ng/mL; contralateral side, 4513+/-787 ng/mL, p = .10). There was no statistical difference for minimal surface tension measured with the pulsating bubble surfactometer after 5 mins of oscillation (contusion side, 29.5+/-2.3 mN/m; contralateral side, 23.7+/-2.1 mN/m; p = .08). CONCLUSIONS: Direct damage of lung parenchyma by lung contusion alters the composition of surfactant. No additional changes in surfactant function were observed that would argue in favor of functional compensation.

Intermittent prone positioning in the treatment of severe and moderate posttraumatic lung injury.

OBJECTIVE: Severe posttraumatic lung injury is characterized by impairment of gas exchange and pulmonary densities. The influence of intermittent prone positioning on pulmonary gas exchange and parenchymal densities was investigated prospectively in patients with pulmonary injury after multiple trauma with blunt chest trauma. SETTING: A six-bed trauma intensive care unit in a university hospital. DESIGN: Prospective, descriptive study. PATIENTS: Twenty-two consecutive patients with pulmonary injury after multiple trauma with blunt chest trauma and acute lung injury (n = 11) or severe acute respiratory distress syndrome (ARDS) (n = 11) according to the definitions of the consensus conference on ARDS. INTERVENTIONS: Pulmonary densities were calculated planimetrically from computed tomographic scans of the chest before the first and after the last cycle of prone positioning. Indications for prone positioning were a) mechanical ventilation with FIO2 >0.5 at positive end-expiratory pressure >10 cm H2O for >24 hrs; or b) pulmonary densities in two or more quadrants being constant or increasing within 48 hrs. Arterial blood gas analysis was performed every 2 hrs. Intrapulmonary right-to-left shunt (Qs/Qt) and alveolar-arterial PO2 difference were calculated 2 hrs after the beginning and end of every prone and supine cycle, respectively. Patients were ventilated in the prone position for 8 hrs each day. MEASUREMENTS AND MAIN RESULTS: Every single posture change from the supine to the prone position resulted in a significant average increase in the oxygenation index of 28+/-8 torr (3.7+/-1.1 kPa) (p<.0001). There was a significant improvement in oxygenation (4.3+/-0.8 torr [0.57+/-0.11 kPa]) with time between two consecutive measurements in the prone as well as the supine position (p<.0001). Alveolar-arterial PO2 difference and Qs/Qt showed a significant decrease of 25+/-7 torr (3.3+/-0.9 kPa) and 1.1+/-0.46%, respectively, for every cycle of prone positioning. Statistical analysis revealed no significant alteration of gas exchange within every prone and supine cycle. Total static lung compliance improved significantly over time (p<.001). However, ventilation of patients in the prone position demonstrated a mean decrease in compliance of 2.1+/-0.72 mL/cm H2O. The response to prone positioning was similar in patients with ARDS and acute lung injury and revealed no significant difference. In both groups, the course of the oxygenation index and Qs/Qt over time was almost parallel. Posture changes were continued for 9.0+/-1.1 days. The oxygenation index showed an overall increase of 129+/-20 torr (17.2+/-2.7 kPa) from baseline supine at the end of prone positioning (p<.0001). Pulmonary densities were reduced significantly from 31.1+/-2.5% to 3.8+/-0.81%, Qs/Qt was reduced from 24.9+/-1.5% to 11.7+/-0.32%, and FIO2 was reduced from 0.43+/-0.04 to 0.26+/-0.02 (p<.01). Gas exchange improved in all patients, and no patient died immediately as a result of respiratory failure. CONCLUSION: Repeated prone positioning recruits collapsed lung tissue and improves gas exchange in trauma patients with blunt chest trauma and severe ARDS as well as in trauma patients with acute lung injury.

[Results of cement-free implanted, Robert Mathys isoelastic acetabular cup].

In 163 patients--125 (76.7%) female, 38 (23.3%) male--172 cementfree isoelastic acetabular cups were implanted. The average patient age was 72.6 years (range: 16 to 96 years). Sixty-seven (41.1%) patients with 72 (41.9%) cups could be followed-up for an average of 6.0 years (range: 2.0 to 12.2 years) after the procedure. Using the Harris-hip-score we found 49 (68.1%) "very good" to "fair" results. In 23 (31.9%) hips scoring had to be classified as "bad". The rate of cup-loosenings in the collective was low at 3.5% (6/172), probably due to the reduced physical activity of our comparatively older patients. Because after the 8th year symptomatic loosening must be routinely expected, the procedure is not indicated for younger patients. In older patients with femoral neck fractures the cementfree isoelastic acetabular cup has proven itself effective in our experience.

[Effect of primary femoral plate osteosynthesis on the course of polytrauma patients with or without thoracic trauma].

Primary intramedullary nailing of femoral fractures is well known to increase the risk of pulmonary complications, especially in multiple-trauma patients with severe thoracic injuries. Aim of this study was to investigate the influence of primary plate osteosynthesis of femur fractures on major complications after trauma. This retrospective study based on the records of 325 multiple trauma patients (Injury severity score ISS > 18, no lethal brain injury, age 16-65). According to the abbreviated injury scale of the Thorax (AIS T) patients were divided in groups without (AIS T < 3, "N") or with relevant thoracic injury (AIS T > = 3, "T"). Both groups were additionally divided in subgroups without severe trauma to the extremities (AIS E < 3, "O") or primary plate-osteosynthesis of femur fractures (< 24 h, "I"). 4 groups were performed: NO (n = 39, ISS 25 +/- 1, pneumonia 10%, ARDS 5%, lethality 10%); NI (n = 55, ISS 27 +/- 1, pneumonia 4%, ARDS 5%, lethality 4%); TO(n = 137, ISS 28 +/- 1, pneumonia 21%, ARDS 15%, lethality 16%); TI (n = 94, ISS 31 +/- 1, pneumonia 21%, ARDS 17%, lethality 15%). Primary plate-osteosynthesis of femur fractures did not increase lethality or incidence of pulmonary complications in patients with or without severe thoracic injuries. Also complication rate after primary plate-osteosynthesis was less compared to published results after intramedullary nailing. For this, primary plate-osteosynthesis is recommendable in case of multiple trauma with thoracic injuries.

[Comparison of severe multiple injuries in childhood and adulthood].

Multiple injuries in children are responsible for a great part of childhood mortality. Remaining handicaps after injuries have a social and economic significance. In this study, the characteristics of polytrauma in childhood are evaluated by comparison with severely injured adults. The two groups of multiple trauma patients (117 children between 3 and 15 years of age and 1159 adults between 16 and 59) were equal in the overall severity of all injuries. Children were mainly hurt as pedestrians, whereas adults had an accident more often as car passengers. The most frequently injured region were in both groups fractures of the extremities. The greatest injury severity represented head injuries in each group. Complications were seen more often in adult patients. Multiple organ failure and isolated liver failure were exclusively seen in the adult group, pneumonia and lung failure occurred significantly more often. The duration of artificial ventilation and the duration of hospital stay were prolonged in the adult group. In summary, children with multiple injuries have a lower mortality rate than adults. The main cause of death are cerebral injuries. Remaining handicaps in surviving children are most often caused by fractures of the lower extremities.

Operative chest wall stabilization in flail chest--outcomes of patients with or without pulmonary contusion.

BACKGROUND: The aim of operative chest wall stabilization in patients with flail chest and respiratory insufficiency is to reduce ventilator time and avoid ventilator associated complications. The purpose of this retrospective study was to analyze the indications and outcomes of operative chest wall stabilization in defined groups of patients sustaining flail chest with and without pulmonary contusion. METHODS: The hospital records of 405 patients with multiple trauma (Injury Severity Score > 17) between 1988 and 1994 were reviewed. Forty-two patients sustained flail chest. Twenty of these underwent operative chest wall stabilization for the following indications: 1) flail chest with indication for thoracotomy due to intrathoracic injury (n = 6); 2) flail chest without pulmonary contusion (n = 9); 3) paradoxical movement of a chest wall segment in the weaning period from the respirator (n = 3); and 4) severe deformity of the chest wall (n = 2). For the purpose of analysis the patients were separated into groups: group 1: operative chest wall stabilization in flail chest without pulmonary contusion (n = 10); group 2: operative chest wall stabilization in flail chest with pulmonary contusion (n = 10); group 3: flail chest without pulmonary contusion and without chest wall stabilization (n = 18); group 4: flail chest with pulmonary contusion and without chest wall stabilization (n = 4). Data were coded for time of operation, duration of ventilatory support, and complications. RESULTS: There were no significant differences in age, severity of injury, and extent of injury between groups 1, 2, and 3 (p < 0.42). Group 4 was excluded for statistical analysis because of the small number of patients. Patients in group 1 required a shorter ventilatory support time compared to patients in group 3 (6.5+/-7.0 versus 26.7+/-29.0 days) and group 2 (p < 0.02). In group 2 (ventilator time 30.8+/-33.7 days) early extubation was only possible in patients being operated on for chest wall instability during weaning from the ventilator. One patient in group 1, three patients in group 2 and five patients in group 3 developed pneumonia with further disturbance of gas exchange. All patients in group 1 survived; deaths in group 2 were attributed to massive hemorrhage in two and septic multiorgan failure in one patient. Four patients in group 3 died of head injury, one of acute respiratory distress syndrome, one of severe hemorrhage, and one of multiple organ failure. CONCLUSIONS: In patients with flail chest and respiratory insufficiency without pulmonary contusion, operative chest wall stabilization permits early extubation. Patients with pulmonary contusion do not benefit from chest wall stabilization. Secondary operative chest wall stabilization in these patients is indicated when progressive collapse of the chest wall is evident during weaning from the ventilator.

[Tikhoff-Linberg interscapulothoracic resection in extra-compartmental tumors of the shoulder girdle].

Ninetten consecutive patients with bone and soft tissue tumors of the shoulder girdle were treated with interscapulothoracic resection (Tikhoff-Linberg procedure) over a 10-year period. Twelve patients were alive with no evidence of disease at a mean follow-up of 6.3 (1-11) years and one patient is alive with local recurrence and pulmonary metastases after 15 months. Six patients died due to pulmonary metastases. Despite these complications, the Tikhoff-Linberg procedure proved to be a valuable operation for extended tumors of the shoulder girdle in terms of functional and oncological outcome and is clearly superior to forequarter amputation.

[Traumatically-induced compartment syndrome of the tibia. Ultrasound diagnosis for qualitative assessment of late sequelae for musculature after dermatofasciotomy].

To determine the significance of sonography in evaluating long-term damage of muscle surgically treated for compartment syndrome 27 patients of the Department for Trauma Surgery, University Clinic Essen, Germany, were examined on their anterior lower limb after an average of 98 (43 to 154) months after trauma. They had had a fasciotomy for imminent (n = 15) or manifest (n = 12) compartment syndrome. Comparing the healthy side a qualitative grading (0 to 3) of the changes could be introduced reflecting the extent of the increase in echogenicity and the loss of the typical muscle texture. Gray scale histograms confirmed the qualitative grading. Patients with manifest compartment syndrome showed severe changes (grade 2 and 3). In imminent compartment syndrome 2 patients with grade 2 and 13 patients with grade 0 or 1 were found. The sonographical changes can be explained by the known pathomorphological changes after compartment syndrome (denervation, scarification). Sonography is useful in the evaluation of soft tissue after compartment syndrome. The results underline the demands of early fasciotomy in imminent compartment syndrome for prevention of damage of muscle and nerve.

[Causation and injury pattern in in-line skating].

Accident proceedings and injuries were investigated in a consecutive series of 70 patients (65.2% male, 34.8% female, age: 18 +/- 9 years) presented to the emergency department after in-line skate falls. 52.7% wore no protective equipment. 41.8% used knee pads, 27.3% wrist guards, 12.7% elbow pads, and 5.5% each helmets and gloves. The most common cause of fall were obstacles/irregularities (32.7%) on a dry and plain surface. The upper extremity (67.9%) and the head (12.8%) were the most commonly injured body parts. 47.8% in-line skaters sustained fractures. The distal radius (51.5%) was most commonly injured body parts. 47.8% in-line skaters sustained fractures. The distal radius (51.5%) was most commonly fractured. Injuries to novice skaters were more often severe. Advanced freestyle and jumping in-line skaters sustained even injuries of the trunk. Life-threatening injuries of the abdomen and the head may occur. The use of a complete personal protection equipment is recommended.
