"Spare part" forearm free flaps harvested from the amputated limb for coverage of amputation stumps.

The use of "spare part" flaps from a non-replantable limb to cover amputation stumps in the upper extremity preserves limb length, provides durable coverage and sensation and will avoid additional donor site morbidity. We have studied the blood supply of the forearm based on the radial artery. The potential for harvesting different tissues is confirmed. In five clinical cases reliable primary soft tissue reconstruction was achieved, even in the presence of trauma.

The vascularization in the amputation stumps of rabbits. A microangiographic study.

With the aid of microangiography the vascularization in the amputation stumps of 108 rabbits was studied, both in extremities with normal circulation and in those supplied with collaterals. It was found that the vascularization of the normal leg was altered by amputation, with the development of newly-formed, pathological, spirally-twisted vessels. Closure of the stump with myoplasty, however, counteracted this vessel formation, and hypervascularization took place through normal arteries. After amputation of extremities supplied with collaterals, the influence of amputation on collateral function and vascularization in the amputation stump was dependent on the time interval between arterial occlusion and amputation.

Bone vascularization and bone healing in the amputation stump. An experimental study.

The osseous healing process of the amputation stump was investigated in adult rabbits. Histological investigation showed that the medullary cavity was closed after 2-3 weeks, chiefly by endosteal callus. After closure of the cavity there was a gradual spongious change in the bone tip and simultaneously the cortex atrophied and the medullary cavity dilated. After amputation on the crus bone rebuilding dominated, whereas after amputation on the femur deterioration of bone was most noticeable. A combination of amputation and medullary plugging caused a change in the course of healing. The medullary cavity did not close until 7-10 weeks after operation and there was distinct periosteal callus formation. The microangiographic investigation showed a transient hypervascularization in the cortex 3-4 weeks after amputation; whereas after simultaneous plugging of the medullary cavity the hypervascularization continued for up to 7 weeks after operation. Following amputation proximally on the crus the arterial supply of the cortex came mainly from the periost, whereas the cortex after distal amputation was vascularized from the medullary cavity. This finding can be due to an interruption of the arterial supply from the nutrient artery associated with proximal amputation, whereas this artery remains intact with amputation distally on the crus.

Spasms of amputation stumps.

Two patients are presented with muscle spasms in an amputation stump. Neither patient experienced neuropathic pain nor phantom sensations, though phantom sensory phenomena, severe pain, and lack of response to treatment is characteristic of reported cases. One patient, a 75 year old man, has had myoclonic activity of the stump for more than two years, and the other, a 79 year old woman, recovered spontaneously after three months and is symptom free after a one year follow up. We emphasise the lack of association with pain and the need to consider spontaneous improvement when therapy is evaluated.

[Kaposiform angiodermatitis (pseudo-Kaposi's disease) on an amputation stump. A new entity].

Kaposiform cutaneous lesions were observed on the amputation stump of a 65-year-old male whose leg had been amputated above the knee. Histological examination revealed pronounced stasis dermatitis. This finding, together with phlebectasias and fine arborized cutaneous varices on the stump end, suggested that the pathogenesis may involve venous congestion. This may be caused by suction in the prosthesis socket and compression of the stump at the socket edge.

Acroangiodermatitis of amputation stump.

Acroangiodermatitis is an angioproliferative disease characterized by pseudosarcomatous papules and plaques. It is often associated with different disorders like: chronic venous insufficiency, artero-venous malformations, artero-venous shunts, paralysed limb. In the case of amputation stumps the traumatic and suctional stimula may be the cause of this reactive pathology. We describe a case of acroangiodermatitis in an above-knee amputation stump in a 48-year-old-female affected by Down's syndrome.

Cortical focusing is an alternative explanation for improved sensory acuity on an amputation stump.

The ability to localize a sensory stimulus on the body surface (locognosia) has been investigated in normal subjects in a quest to find an explanation for the reported findings of improved sensory acuity on an amputation stump. We have shown that when attending to a smaller area of skin, during the testing procedure, locognosia improves (P < 0.001) by a similar degree to that seen in amputees. Such selective attention is likely to occur in upper limb amputees as they have a reduced area of skin on which to focus during sensory testing. This represents a further explanation for improved sensory acuity on an amputation stump without implicating plasticity of connections within the somatosensory cortex.

Modified "on-top-plasty" technique for restoring length to amputation stumps.

Five patients were successfully treated with a modified "on-top-plasty" technique, in which a finger stump is lengthened by transfer of an adjacent amputation stump with a reverse blood flow fingerstump. This technique can be performed in the acute phase or as a secondary procedure. A conventional on-top-plasty can be performed by transfer of a partially amputated index or ring finger to the "top" of the proximal phalanx of an amputated middle finger. Alternatively, the transferred part may be used in an intercalated fashion to reconstruct the middle phalanx, using a prosthesis to reconstruct the proximal interphalangeal joint. The results, complications and disadvantages of the technique are reported. We propose this procedure for the reconstruction of the middle ring finger when a free microneurovascular toe-to-hand transfer is contraindicated or refused by the patient.

The osteosarcoma amputation stump: a clinico-radiographical correlation.

The radiological picture of the amputation stump after osteosarcoma was reviewed in 75 cases, in which postoperative follow-up ranged from a minimum four months, to a maximum of over 12 years. In 67/75 cases (89%) no recurrence was observed; in 8/75 cases (11%) a local neoplastic recurrency was confirmed on clinical and histopathological grounds. The usual aspects of late modifications induced by surgery include osteoporosis of the residual bone, which may assume a geographical pattern, with thinning of the stump apex and formation of a periosteal spur directed towards the soft tissues. The typical pattern of locally recurrent osteosarcoma is that of an infiltrating soft tissue mass with bone erosion and irregular flake-like calcifications. All these signs are presented and discussed in order to give a practical guideline to the differential diagnosis between surgery-induced modifications and local neoplastic recurrences.

[Use of "foot-bank" tissue to cover amputation stumps. Apropos of 4 cases].

PURPOSE OF THE STUDY: The authors report 4 cases of plantar skin free transfer to cover an amputation stump. MATERIAL AND METHODS: In two cases, operated as emergencies, a flap based on the posterior tibial pedicle was harvested from a non-reimplantable extremity. In one case the calcaneum was included in the flap to provide a stump wide enough to hold a prosthesis. The two others cases concerned planned amputation of non-functional extremities, with free transfer of the available plantar skin areas. RESULTS: All 4 patients healed well and the skin coverage provided a good quality stump which was rapidly equipped with prostheses. DISCUSSION: Covering amputation stumps with a free flap from the foot bank has proven to be a reliable procedure, economic for the patient, affording a good physiologic bearing surface. CONCLUSION: This method should proposed in emergency amputations according to local conditions, and may also be advantageous in some cases of secondary surgery.
