The use of combination internal fixation and hybrid external fixation in severe proximal tibia fractures.

Forty-eight patients with 50 severe fractures of the proximal tibia were followed prospectively for 2-4 years (mean 2.7 years) to evaluate the use of limited internal fixation combined with external fixation in the treatment of these injuries. There were 27 men and 21 women ranging in age from 20 to 74 years. Fractures were classified according to the A0 system (Mast J, Ganz R, Jacob R: Planning and reduction technique in fracture surgery. Berlin, Springer-Verlag, 1989), which included 5 A3, 6 C1, 16 C2, and 23 C3 fractures. All patients in this series healed; 48 fractures healed in an average of 12 weeks without subsequent surgery. There were two (4%) nonunions requiring bone graft. The average hospital special surgery knee score was 90 (68-100). Grading criteria for anatomical outcome revealed there were 17 (34%) excellent results, 24 (48%) good results, 6 (12%) fair results, and 3 (6%) poor results. In conclusion, this treatment method is associated with a high percentage of good and excellent results. Combined internal and external fixation combines the advantages of anatomic, stable fixation with less soft-tissue dissection and eliminates the need for large implants.

Treatment of grade-IIIb open tibial fractures. A prospective randomised comparison of external fixation and non-reamed locked nailing.

Severe open fractures of the tibia have a high incidence of complications and a poor outcome. The most usual method of stabilisation is by external fixation, but the advent of small diameter locking intramedullary nails has introduced a new option. We report the early results of a randomised, prospective study comparing external fixation with non-reamed locked nails in grade-IIIb open tibial fractures. Of 29 patients, 15 were treated by nails and 14 by external fixation. Both groups had the same initial management, soft-tissue procedures, and early bone grafting. All 29 fractures healed within nine months, but the nailed group had slightly better motion and less final angulation. Complications included one deep infection and two pin-track infections in the external fixator group and one deep infection and one vascular problem in the nailed group. Although the differences in healing and range of motion were not statistically significant, we found that the nailed fractures were consistently easier to manage, especially in terms of soft-tissue procedures and bone grafting. It is the treatment preferred by patients and does not require the same high level of patient compliance as external fixation. The only factors against nailing are the longer operating time and the greater need for fluoroscopy. We consider that locked non-reamed nailing is the treatment of choice for grade-IIIb open tibial fractures.

Pilon fractures: treatment with combined internal and external fixation.

The purpose of this study was to prospectively evaluate the use of limited internal fixation and the application of a hybrid external fixator (tensioned wires distally and 5.0 mm half pins proximally attached to a semicircular frame without crossing the ankle joint) in the treatment of severe distal tibia fractures. This technique involves accurate reduction and fixation of the intraarticular component through an incision based over a fracture site followed by stabilization of the metaphysis with the hybrid external fixator. We studied 26 patients 15-55 years of age who were followed for 8-36 months. All fractures were within 5 cm of the joint. Seventeen fractures were intraarticular, nine extraarticular, and six open. Eleven patients required bone grafting. The average time to healing was 4.2 months. Using clinically based criteria, there were 81% good and excellent results overall, 70.5% for the 17 intraarticular fractures, and 69% for Ruedi type III fractures. Complications included one superficial and one deep infection, one 10 degrees varus malunion, and three pin tract infections. This method yielded results comparable with previous studies while reducing the amount of soft tissue dissection necessary for the placement of large plates. Soft tissue complications were infrequent and the goals of early motion and fracture stability were not sacrificed.

[Basic and advanced training in radiation protection in stomatology].

Considering the importance of radiation protection in dental radiology and the respective legal regulations of the GDR, objectives and contents of basic and advanced training of responsible co-workers in radiation protection are described. Particular organisational aspects regarding training courses in the National Board for Atomic Safety and Radiation Protection are outlined.

Treating geriatric depression: a 26-week interim analysis.

Two concurrent studies of geriatric outpatients who received diagnoses of depression were conducted. In the first, patients were treated with one of two tricyclic antidepressants or with a placebo. In the second, patients were assigned to groups receiving either psychodynamic group therapy or cognitive-behavioral group therapy. Patients in the placebo group showed the least improvement; most patients receiving group psychotherapy showed some improvement, but only 12% had full remissions; by contrast, 45% of patients receiving imipramine or doxepin had full remissions, while 36% of them experienced little or no benefit. An early response to tricyclic antidepressant drugs was a reliable predictor of continued improvement.

"Critical loss" in the eighth and ninth decades.

Data from the last survivors of the New York State Psychiatric Institute Twin study were examined to determine if the previously identified relationship between "critical loss" and 5-year survivorship still held true for persons in their eighth and ninth decades of life. Twenty-two subjects (age range 83 to 99 years) were tested in 1973 and by 1978, 12 had died, making it possible to retrospectively examine the relationship between survivorship and critical loss. "Critical loss" did not distinguish survivors from decedents, but presence or absence of OBS did distinguish the groups, with seven of eleven decedents and none of eight survivors being so diagnosed. Survivors did not differ significantly from non-survivors in annual rate of decline on any of the three "critical loss" tests (Vocabulary, Similarities, Digit Symbol Substitution), though survivors had higher mean scores on all three tests.

Depression, physical health and somatic complaints in the elderly: a study of the Zung Self-Rating Depression Scale.

The relationships between depression, measured by the Zung Self-Rating Depression Scale (SDS), somatic symptoms based on self-reports, and health based on medical evaluations, were investigated in 60 depressed older persons (median age 64.5 years) in relatively good physical health. No relationship was found between health ratings and depression scores, but a significant association emerged between a Somatic Symptom subscale, specifically the single item of fatiguability, physicians' ratings of health, and depression scores. Results of factor analyses of the Zung Self-Rating Depression Scale were similar to those reported in previous studies and indicated a factor structure apparently based on the positioning of the positively and negatively worded items. It is suggested, therefore, that further investigations be carried out to evaluate the possible response bias on this scale.

Family abuse of the elderly.

In 12 cases of family abuse of disabled elderly persons, the majority of the abused were women. Caretakers included spouses, children, siblings or other relatives. Abuse was both physical and verbal/psychologic. Neglect, the most common form of physical abuse, sometimes resulted in decubitus ulcers and vermin infestation. Misuse of medical therapy and nutrition were other areas of physical abuse. Psychologic abuse included derogation, infantilization, and threats of institutionalization, abandonment, and homicide. Possible causes of abuse included alcoholism in the caretaker, financial concerns, and long-term family conflicts. Various recommendations are made for the management of abusive families.

Treatment of geriatric depression with trazodone, imipramine, and placebo: a double-blind study.

Sixty unipolar depressed geriatric outpatients were subjects in a double-blind study of a new antidepressant, trazodone, versus imipramine and placebo. Over the four week study, patients in the two active medication groups improved significantly compared to placebo on both observer and self-ratings. Although imipramine and trazodone had similar therapeutic efficacy, trazodone was judged to have fewer side effects than imipramine, suggesting that trazodone may have particular clinical utility in the geriatric population which is especially vulnerable to cardiovascular and anticholinergic side effects.
