Tail regeneration in the plethodontid salamander, Plethodon cinereus: induced autotomy versus surgical amputation.

Regeneration of the tail in the plethodontid salamander, Plethodon cinereus, occurs following either surgical amputation or induced autotomy. Autotomy may occur along any one of the caudal myosepta which form natural cleavage planes. The distally attached myofibers break away from the myoseptum which then becomes part of the stump surface remaining intact during subsequent regeneration of the distal segments. Under these conditions, therefore, muscle fibers do not normally participate in tail regeneration. If, however, the myofibers of a caudal myotome are interrupted as in mid-segment amputation, the damaged fibers undergo hyaline degeneration and are largely replaced by connective tissue often as far proximally as the next myoseptum. Other tissues at the amputation surface are concurrently engaged in the epimorphic regeneration of the tail, including myogenesis, though at a slower initial rate than that following autotomy. Muscle cells, therefore, appear not to participate in epimorphic tail regeneration in Plethodon cinereus following either surgical amputation or induced autotomy.

[Surgical amputation and prosthetic management in congenital fibrosarcoma of the lower extremity].

The concept of surgical amputation and the problems of prosthetic management in a girl with congenital fibrosarcoma of left distal thigh, knee and shank is described. After failed polychemotherapy (EICESS 92) and expansion of the tumor a radical knee disarticulation and intended marginal resection of the tumorous soft tissue area of the distal thigh was performed at the age of eleven months and two weeks. The femur was shortened by osteotomy of the diaphysis and removing a fragment in order to protect the distal femoral epiphyseal growth plate and to be able to close the soft tissue of the stump primarily. Prosthetic fitting and rehabilitation started at the beginning of statomotorical development at the point when four feet standing changed into two feet standing. In present, at the age of two years and six months, this girl is independent mobile and well fitted with a knee disarticulation prosthesis.

Amputation: surgical technique and postoperative management.

The decision to amputate should be made with due consideration of the eventual rehabilitation of the patient. With this in mind, general principles of amputation surgery are outlined and specific levels of amputation are described. Early post-amputation management has advanced over the last two decades to make rehabilitation goals the more readily reached. These advances are discussed.

Psychiatric and emotional sequelae of surgical amputation.

The prevalence of posttraumatic stress symptoms after the experience of amputation is not well established. The current study gathered data on the prevalence of posttraumatic stress disorder (PTSD) and other psychiatric disorders after amputation. Participants were recruited from a large Northeastern rehabilitation hospital and were assessed with structured clinical interviews. The data suggest that planned surgical amputations resulting from chronic illness do not frequently lead to PTSD symptoms. In contrast, data suggest that amputation resulting from accidental injury may lead to a higher prevalence of PTSD, in part because of the emotional stress surrounding the accident.

[Gritti's amputation. Surgical technic, apparatus and indications].

The amputation proposed by R. Gritti in 1857 involves a supracondylar operation with repair surgery to the patella, which is attached to the femur, allowing a long stump to be maintained. Principal criticisms were related to the apparatus used, until be availability of a prosthetic knee occupying minimal spaces and allowing alignment with the healthy knee. Weight bearing is terminal with a light prosthesis that locks in without difficulty. It can therefore be substituted for conventional lower third of thigh amputations in certain cases.

Syme's amputation. Surgical technique, prosthetic considerations, and case reports.

Amputation at the level of the ankle joint is a valuable but underused procedure for a variety of conditions affecting the foot and ankle. The procedure provides a comfortable and durable stump that allows the lower-extremity amputee to function with minimal disability. This article reviews the indications for Syme's amputation, provides a detailed surgical description of the procedure, and discusses postoperative prosthetic considerations. In addition, three case reports are presented in which Syme's procedure was successfully used as an alternative to higher-level amputation.

[Sphincter-saving procedure of abdomino-peritoneal amputation? Surgical management of cancer of the lower two third of the rectum].

UNLABELLED: The authors report their results in surgical treatments of carcinoma localized in the low two thirds of the rectum done between 1980 and 1988. The number of patients was 150. Resectability: 119/150 = 79.33 per cent. Lethality: 4/119 = 3.3 per cent. Seventy three of the patients (61 per cent) had sphincter saving procedures and 46 of them (38.7 per cent) had abdominoperineal excision. Out of the 64 low anterior resection 2 patients (L: 2/64 = 3.1 per cent) and out of the 46 abdominoperineal excision also 2 patients (L: 2/46 = 4.5 per cent) were lost. In the sphincter saving group the distal clearance margin was decreased to below 3 cms at 29 patients without having local recurrence. CONCLUSION: in many cases of the carcinoma localized in the middle third of the rectum (at 82 per cent of our own patients) the sphincter can be saved without having more local recurrences. Decreasing the distal clearance margin to 2.5 cms does not increase the possibility of local recurrence if we do it cranially the same way as at Miles operation and remove the mesorectum caudally and laterally.

Prosthetic fitting immediately after below-knee amputation.

Frequently surgical amputation of a lower extremity is required when gangrene develops as a result of peripheral vascular disease. This is particularly true in geriatric patients. A below-knee amputation, with refinements in the surgical procedure, and immediate rigid-cast prosthetic fitting are strongly advocated by our group. The progress of two patients treated in this manner is described. Preservation of the knee joint improves the amputee's prognosis for ambulation with a below-knee prosthesis. The rigid-cast dressing on the below-knee amputation reduces edema and postoperative pain, is of psychologic value to the patient, and permits him to stand at from one to two days postoperatively.
