Free vascularized growth-plate transfer after bone tumor resection in children.

Limb-salvage surgery is the standard care for most malignant tumors affecting the extremities, and a vascularized fibula transfer is probably the most popular microsurgical option to reconstruct long-bone defects. Skeletal reconstruction after bone-tumor resection involving the metepiphysis of a growing child can be successfully achieved with a vascularized fibula graft incorporating the proximal physis and active growth plate. Such a procedure has been utilized in 12 children under the age of 10 years who had malignant bone tumors located in the upper limb (3 in the distal radius, 9 in the proximal humerus). The follow-up ranged between 4 years and 3 months. Ten grafts were supplied by the anterior tibial artery, and two by the peroneal artery. The average growth rate of the grafts based on the former artery has been more than 1 cm per year, ranging between 0.75 and 1.33 cm. The authors describe a modified operative technique and discuss the clinical results of the procedure which offers a satisfactory skeletal reconstruction and prevents future limb-size discrepancy.

[Reconstruction with free vascularized or island flaps of soft tissue loss in the upper limb after tumor resection. 16 cases].

We have reviewed 16 cases of soft tissue sarcomas of the upper limb treated with wide excision of the tumour and immediate soft tissue reconstruction by means of a microvascular flap. 9 patients were males, 7 females; age ranged from 12 to 74 years. All the patients had been referred to us after previous failed or inadequate excisions. All the tumours were high-grade malignancies in an extracompartmental location (stade IIB according to Enneking). Histopathologic diagnosis was: synovial-sarcoma in 11 cases; fibrosarcoma in 2 cases; malignant fibrous histiocytoma in 1 case, soft tissue osteosarcoma in 1 case, epitheloid sarcoma in 1 case. The site of the tumour was the hand in 2 cases, the wrist in 6 cases, the forearm in 5 cases and the elbow in 3 cases. The free flaps used for soft tissue reconstructions were the latissimus dorsi in 6 cases, the dorsalis pedis in 2 cases, the lateral arm flap in 2 cases, the serratus in 1 case, the gracilis in 1 case. The island flaps were the radial forearm flap in 1 case, the posterior interosseous flap in 1 case, the cubital flap in 1 case. 14 cases required immediate associated reconstructive procedures such as tendon transfers or grafts (5 cases), vascularized or non vascularized bone grafts (4 cases), articular allografts (1 case), ligament reconstruction (1 case), nerve grafts (2 cases). Brachytherapy was associated to microsurgical reconstruction in the last 6 cases of this group. The catheters were charged with the radioisotope 5 days after surgery. No complications were observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Diabetic hand syndrome.

Diabetic hand syndrome is a condition affecting about 30% of patients with insulin-requiring juvenile diabetes. Characteristic findings in this syndrome are mild- to- moderately severe joint contractures of the fingers, particularly at the proximal interphalangeal joints in the ring and small fingers, and thickening of the skin of the dorsum of the hand. There is no evidence of palmar fascial thickening or Dupuytren's contracture. Occasionally other joints may be involved, such as the wrists, elbows, hips, knees, and toes. In the case presented in this report light and electron microscopic studies showed that the disease presents aspects similar to those of other "fibrotic diseases" as described by Kisher and Speer. Surgical treatment was only partially beneficial in this patient.
