Psychological adjustment in children after traumatic disfiguring injuries: a 12-month follow-up.

The psychological adjustment of 57 children (age range, 3 to 12 years) who sustained mutilating traumatic injuries to the face or upper or lower extremities was assessed over a 12-month interval. The injuries had occurred as a result of boating, lawn mower, or home accidents or dog bites. Within 5 days of the traumatic event, 98 percent of the children were symptomatic for posttraumatic stress disorder, depression, or anxiety. One month after the injury, 82 percent were symptomatic. Symptom frequency had declined by the time of the 3-month and 6-month evaluations, but 44 percent of the children continued to report symptoms at 12-month follow-up visits, and 21 percent met the diagnostic criteria for posttraumatic stress disorder. Typical symptoms included flashbacks, fear of re-injury, mood disorders, body-image changes secondary to disfigurement, sleep disturbances, and anxiety. These findings support the importance of psychological evaluation and treatment of children who suffer mutilating injuries that require the attention of plastic surgeons.

Psychometric assessment of patients with chronic upper extremity pain attributed to workplace exposure.

Upper extremity pain attributed to workplace exposure is a growing concern in medicine today. This study was undertaken to investigate the psychological findings in patients with chronic upper extremity pain attributed to workplace exposure. Sixty-three consecutive patients were evaluated. All patients underwent a history and physical examination by a hand surgeon and a psychological evaluation by a licensed psychologist, including a Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Physical and psychological findings were then compared. Forty-one patients (65%) showed abnormalities on MMPI-2 examination (t score > 70 = 97% confidence). This result is far above what generally would be expected in medical patients. When physical findings were grouped with psychological findings, 5 distinct groups were identified: 1 patient had normal physical and psychological results, 6 patients had normal physical findings but abnormal psychological assessments, 21 patients had abnormal physical findings but normal psychological assessments, 28 patients had both abnormal physical and psychological findings, and 7 patients had abnormal physical results but invalid MMPI-2 evaluations due to purposeful attempts to deny psychological symptoms. Identification of these groups may have diagnostic, prognostic, and treatment value. In addition, identification of these groups may help clarify several aspects of the debate over the role of psychosocial factors in the development and maintenance of chronic upper extremity pain that patients attribute to workplace exposure.

Analysis of the distribution of cutaneous perforators in cutaneous flaps.

An anatomic and statistical analysis was performed on the distribution of cutaneous perforators that perfuse the scapular, radial forearm, and lateral arm cutaneous flaps. Perforators were categorized as direct, terminal, and intransitive, depending upon perforator origin and termination site relative to the source artery. Statistical cluster analysis of perforator distributions was performed to determine the regions in which cutaneous perforators are consistently found. The scapular and radial forearm flaps could be divided into up to three well-perfused segments. The analysis predicted the possibility of dividing the lateral arm flap into as many as seven segments while maintaining perfusion. Clinical applications of this method for preoperative flap design and elevation as well as final results are shown.

Multidisciplinary management of altered body image in the patient with an ostomy.

Many clinical studies have found patients with ostomies to be a group facing multiple adjustment demands. One of these demands is coping with a significant change in body image. At the Medical College of Wisconsin, a team approach has been initiated; the ET nurse, the psychologist, and the surgeon deal with body image concerns together. Problems requiring counseling have included difficulty with personal acceptance, personal and social body-image disruption, sexual concerns, reduced self-care skills, and the management of surgical complications. This article represents a study employing a methology of selected case presentations. Cases were chosen to outline the types of problems encountered and were selected from referrals made for psychologic intervention by the surgeon and ET nurse. The patients included four women and three men, ranging in age from 22 to 79 years. Data were compiled by examining the records of the surgeon, ET nurse, and psychologist. The primary needs revolved around personal or social acceptance of altered body image. By addressing these needs in a straightforward, time-limited manner, postsurgical counseling was delivered effectively for these patients. In conclusion, we have demonstrated the multidisciplinary approach to be successful in facilitating adaptation to an altered body image.

What influences public perceptions of silicone breast implants?

In an effort to determine public attitude regarding breast implants in the wake of what many might consider biased media publicity, surveys of women and men in Milwaukee were made. Questionnaires appropriate to each of four groups [patients with reconstructions (n = 54), mastectomy without reconstruction (n = 14), those with augmentation mammaplasty (n = 26), and the general public (n = 60)] were administered. Some of the findings included the following: Over 98 percent had heard of the controversy; most had received their information from the media, with less than 10 percent referring to a medical journal; only 6 percent felt that the media coverage was objective, while 88 percent felt that the media were biased; almost two-thirds of those in the general population were not aware of any other method of reconstruction; and almost half that same group would have significant hesitancy in having the procedure on themselves or a family member were it indicated. In summary, our findings would substantiate the fact that the media do exert a very significant influence on the public's perception of silicone breast implants. Though most people surveyed generally consider the media biased, they still use them as the primary source for their negative conclusions on the matter. Though the media cannot be viewed as our ally in this matter, we, as a group, might be better served by minimizing conflict, which makes the whole issue less newsworthy.

A comparison of upper arm and forearm tourniquet tolerance.

This study examined the use of upper arm and forearm tourniquets for hand surgery. 40 subjects (20 males, 20 females) were randomly assigned to one of four groups: left upper arm, left forearm, right upper arm and right forearm. Tourniquets were applied to these areas. Subjects were asked to rate their discomfort at 10-minute intervals and the total time of tourniquet tolerance was recorded. The results of a three-factor ANOVA revealed no statistically significant differences in either pain rating or tourniquet tolerance between any of the groups. In addition, forearm tourniquets were used in 18 clinical cases. None of the individuals with tourniquet times less than 30 minutes required any medication in order to tolerate this procedure. Of the 13 patients with tourniquet times greater than 30 minutes, ten required medication in order to tolerate the procedure. We conclude that patients tolerate upper arm and forearm tourniquets equally.

Spiral fracture fixation techniques. A biomechanical study.

The mechanical strengths of five common fixation techniques for spiral fractures have been tested. A total of 240 cadaver metacarpals and proximal phalanges were fractured and fixed by either crossed K-wires, interosseous loops, a dorsal mini-plate, a single compression screw or K-wire plus cerclage wire. Specimens were subjected to torsional and cantilever bending tests. A single compression screw provided the best overall fixation for the proximal phalanx. In addition, a single compression screw provided better fixation than any of the other techniques when proximal phalanges and metacarpals were subjected to torsional tests (P < 0.05). In apex dorsal bending tests of metacarpals, the screw provided fixation superior to interosseous wires, crossed K-wires, or dorsal mini-plates (P < 0.05). These results indicate that the use of a single compression screw provides the most satisfactory biomechanical advantage for spiral fracture fixation.

Psychological adjustment to hand injuries: nursing management.

Traumatic hand injuries can be devastating experiences both physically and psychologically. The plastic surgery nurse who can identify the various responses that routinely occur with hand injured patients is better prepared to normalize their experiences and implement the necessary interventions toward overall rehabilitation. This article will provide an overview of specific characteristics and emotional reactions following hand injuries, factors that influence adjustment, and nursing management that promotes optimal recovery.

Predictive value of psychological screening in acute hand injuries.

Difficulties in adjustment frequently accompany severe hand injuries. The purpose of this study was to determine whether presurgical screening could predict long-term adjustment problems. One hundred thirteen patients with severe hand injuries completed a presurgical questionnaire evaluating flashbacks, avoidance, and causal factors pertaining to the injury. Patients were evaluated by a psychologist within 5 days after surgery and again 6 months later. Flashbacks initially occurred with equal frequency in occupationally and nonoccupationally injured groups. At 6-month follow-up 50% of the occupationally injured patients and 25% of the nonoccupationally injured patients had flashbacks. Avoidance of the activity at which patients were injured was also assessed. Among occupationally injured patients, 52% initially reported no avoidance compared with 17% at follow-up. Patients with nonoccupational injuries showed more initial avoidance (68%), with slightly less at follow-up (61%). Of the occupationally injured patients, 46% initially reported personal error or fatigue as the cause of their injury, but only 6% reported this as the cause at follow-up; it is interesting that at 6-month follow-up 81% of this group reported machine failure or lack of safeguards. Among nonoccupationally injured patients, 71% reported personal error as the cause of injury presurgically and 66% at 6-month follow-up. Presurgical screening appears to be a valid means of identifying persons at risk of ongoing adjustment problems after hand injury. A screening interview can easily be conducted in less than 5 minutes.

The transverse gracilis musculocutaneous flap.

Through detailed anatomical study and latex injection of 24 cadaver legs, the blood supply to the skin overlying the gracilis muscle was examined. The proximal pedicle entered the gracilis muscle 10 +/- 2 cm below the pubic tubercle. The dissections identified both septocutaneous and musculocutaneous perforators from the proximal gracilis pedicle. These branches had a pronounced tendency to travel in a transverse direction, supplying the cutaneous territory over the adductor longus and sartorius anteriorly and extending for > 5 cm beyond the posterior margin of the gracilis muscle. This information led to a "new" transverse design of the gracilis musculocutaneous flap, such that the vascular perforators are invariably included in the cutaneous portion of the flap. In contrast, the traditional design, because of skin mobility, may allow elevation outside the skin territory of the muscle perforators.

Characteristics of prosthetic mesh and autogenous fascia in abdominal wall reconstruction after prolonged implantation.

This study evaluated two types of prosthetic mesh and autogenous fascia in long-term abdominal wall reconstruction for rats. Marlex mesh, Gore-Tex patch, and autogenous fascia were implanted and left in place for 1 year. Materials were removed and evaluated using tensile strength of the material, tensile strength of the suture line, and adhesions. No change in the tensile strength of any of the materials were found at 1 year follow-up. Tensile strengths were significantly greater for Gore-Tex patch and Marlex mesh than the autogenous fascia. The Marlex mesh, however, had a weak and a strong tensile strength direction. These were significantly different (p < 0.05). Suture line tensile strength was greater for autogenous fascia and Marlex mesh than it was for the Gore-Tex patch, which was significantly weaker (p < 0.05). The greatest number of adhesions were seen in the Marlex mesh group. No significant difference was present in adhesions between Gore-Tex patch and autogenous fascia. In summary, autogenous fascia showed virtually no adhesions and good suture line strength. While it was the weakest of the three materials examined, the strength was still within the normal range and adequate for abdominal wall reconstruction.

Coverage of widely separate defects of the lower extremity: application of cluster analysis.

A patient with lower extremity reconstruction is presented with a radial forearm free flap designed using the cluster analysis method of cutaneous perforators. The cutaneous vascular anatomy of fasciocutaneous flaps is discussed as well as the application of the mathematical model of analysis of the vascular territories within specific flaps to assist in "custom" flap design. The ultimate goal of this technique is the creation of flaps that provide a more precise and anatomical reconstruction of the proposed defect.

Graded work exposure to promote work return after severe hand trauma: a replicated study.

Fifty-one patients with posttraumatic stress disorder after work-related hand injuries were placed on a graded work exposure program to facilitate return to work. These patients consisted of an initial group of 25 patients and a replication group of 26 patients. The program returned 92% of the initial group and 88% of the replicated group to work with their previous employers. At 6-month follow-up, 88% of the initial group and 80.1% of the replication group were still working full-time at the jobs to which they had returned. All of the patients not working with their previous employer at follow-up had appraisal/projected flash-backs, which have previously been associated with a 90% failure to return to work. This intervention was successful with 73% of the patients experiencing such flashbacks. In conclusion, graded work exposure was an effective treatment to promote return to work for patients experiencing significant psychological symptomatology after severe hand injury.

Psychological adjustment following work-related hand injury: 18-month follow-up.

Severe, work-related hand injuries are often accompanied by a significant number of psychological symptoms that are frequently associated with posttraumatic stress disorders. These symptoms occur in the following four domains of psychological functioning: cognitive, affective, physiological, and behavioral. This study examined the incidence of a variety of symptoms occurring with work-injured patients. Interviews were conducted at 1 week, 3 months, 6 months, 12 months, and 18 months after injury. Symptom frequencies were recorded. The results indicate that many of these symptoms were persistent 18 months later and continued to be significantly debilitating. The results support the need for psychological intervention after severe, work-related hand injuries.

Classification system for factitious syndromes in the hand with implications for treatment.

We evaluated 29 patients with factitious disorders in the hand who received Worker's Compensation benefits. Three types of factitious hand disorders based on physical presentation were self-mutilation and wound manipulation, edema, and finger and hand deformities. Two distinct psychological diagnoses present were factitious disorder with physical symptoms and conversion disorder. The Minnesota Multiphasic Personality Inventory revealed two personality profiles: emotionally dependent and angry and hostile. Behavioral treatment was implemented. The emotionally dependent group responded well, with 80% returning to work. The angry and hostile group had a much poorer response, with 21% returning to work. None of the self-multilating patients returned to work. We recommend a combined evaluation by a physician, a psychologist, and a hand therapist to achieve a definitive diagnosis for these disorders. The identification of psychological profiles assists in ascertaining which patients will be responsive to behavioral treatment.

Effects of litigation on maintenance of psychological symptoms after severe hand injury.

Severe psychological symptoms after severe work-related hand injury, manifested as posttraumatic stress disorder, are not significantly potentiated or sustained by concomitant litigation if the patient has had early psychologic intervention. This study does not support assumptions about "accident neurosis" that delays recovery from the psychological sequelae of severe work-related hand injury.
