Simple method for reconstruction of the cleft hand with an adducted thumb.

We describe a new, simple method for reconstruction of a cleft hand. Ulnar transposition of the index ray followed by creation of a thumb web space is an effective way to get sufficient abduction of the thumb. This procedure is simpler than the traditional "translocation of the flap," and also it produces no circulatory troubles to worry about.     

Soft-tissue flap coverage maximizes limb salvage after allograft bone extremity reconstruction

Limb salvage after extremity tumor ablation may include the use of allograft bone. The primary complication of this method is infection of the allograft, which can lead to limb loss in up to 50 percent of cases. The purpose of this study is to evaluate the efficacy of primary muscle flap coverage in the setting of allograft bone limb salvage surgery. This study is a prospective review of all patients with flap coverage of extremity allografts over the 10-year period 1991 to 2001. There were 20 patients (11 male and nine female patients) with an average age of 28 years (range, 6 to 72 years). Flap coverage was primary in 16 patients and delayed in four. Delayed coverage was performed for failed wounds that did not have a primary soft-tissue flap. Pathologic findings included osteosarcoma in nine patients, Ewing sarcoma in five patients, malignant fibrohistiocytoma in two patients, chondrosarcoma in two patients, synovial sarcoma in one patient, and leiomyosarcoma in one patient. Allograft reconstruction was performed for the upper extremity in 12 patients and for the lower extremity in eight patients. Flap reconstruction was accomplished with 20 pedicle flaps in 17 patients (latissimus dorsi, 12; gastrocnemius, four; soleus, three; and fasciocutaneous flap, one) and four free flaps (rectus abdominis, three; latissimus dorsi, one) in four patients. All pedicled flaps survived. There was one flap failure in the entire series, which was a free rectus abdominis flap. This case resulted in the only limb loss noted. The follow-up period ranged from 1 to 50 months (average, 12.35 months). At the time of final follow-up, three patients were dead of disease and 17 were alive with intact extremities. The overall limb salvage rate in the setting of bone allograft and soft-tissue flap coverage was 95 percent (19 of 20). Reoperation for bone-related complications was required in 50 percent (two of four) of cases receiving delayed flap coverage compared with 19 percent (three of 16) of patients with primary flap coverage (statistically not significant). The results of this study support the use of soft-tissue flap coverage for allograft limb reconstruction. In this series, no limb was lost in the setting of a viable flap. Reoperation was markedly reduced in the setting of primary flap coverage. Pedicled or microvascular transfer of well-vascularized muscle can be used to wrap the allograft and minimize devastating wound complications potentially leading to loss of allograft and limb.     

Microvascular soft-tissue transplantation for reconstruction of acute open tibial fractures: timing of coverage and long-term functional results.

Seventy-two patients with Gustilo grade IIIB open tibial fractures were treated with free-tissue transfers. If successful free-tissue transfer for soft-tissue reconstruction is performed within 15 days of injury, the risk of major complications is 3.6 percent. Long-term retrospective follow-up (mean 42 months) revealed successful limb salvage in 93 percent, good aesthetic results in 80 percent, and patient satisfaction in 96 percent. However, 66 percent of patients exhibited significantly decreased range of motion of the ankle, 44 percent experienced swelling and edema requiring elastic support and activity modification, and 50 percent occasionally required an assistance device for ambulation. The long-term employment rate was 28 percent, and no patient returned to work after 2 years of unemployment. In contrast, 68 percent of amputees after lower extremity trauma over the same period returned to work within 2 years. Patients need to realize the disruptive nature of this injury on their family, job, and future.     

Chest-wall deformity following soft-tissue expansion for breast reconstruction

We have presented a case in which the presumed pressure effects of tissue expansion caused multiple nondisplaced rib fractures of the anterior thorax in a patient undergoing breast reconstruction. Although the deformity was severe, a satisfactory cosmetic result was obtained and there have been no clinically significant sequelae during a 1-year follow-up period. The degree of bony deformation was most likely enhanced by the combination of this patient's severe osteoporosis, chronic steroid use, and peripheral vascular disease. The fragility and ease of fracture in the bones of osteoporotic postmenopausal females and the long-term effects of steroids on tissues is well known. We believe this observation to be important, since many reconstructed patients are postmenopausal and have variable degrees of osteoporosis. Many undergo adjuvant chemotherapy with steroids and antihormonal agents, and this group of women may therefore be at a greater risk for the occurrence of pressure deformities. The incidence and long-term significance of such deformities are not known. The reconstructive surgeon should be alert to the possibility of this phenomenon occurring as a result of tissue expansion in the patient with severe osteoporosis, peripheral vascular disease, or chronic steroid use.     

A modification of the great-toe transfer for thumb reconstruction

A modification of the great-toe-to-thumb transfer is presented, which includes sculpting the transferred toe with removal of soft-tissue pulp and bone from the lateral side of the toe. This modification provides the aesthetic advantages of the wrap-around flap while avoiding problems of bone graft resorption, pulp mobility, and a very difficult dissection. Function in our three patients has been excellent.     

Pollicization for thumb reconstruction in severe pediatric hand burns

Our experience in pollicization of the index ray for severely burned hands in children is reviewed with attention to severity of burn, functional impairment, age at pollicization, procedure used, operative time, length of hospital stay, and long-term functional results. Fifteen pollicizations were performed in 11 patients with an average follow-up of over 5 years. Indication for pollicization was lack of prehension due to total loss of the thumb with the presence of a transposable index ray. The bipedicle flap method was used in two cases and the neurovascular pedicle technique was employed in all others. Skin grafts were necessary in all cases. Results were graded according to presence or absence of tip pinch, key pinch, grasp, and opposition. Significant functional improvement was seen in 14 of 15 cases (94 percent). Four patients (27 percent) developed complications requiring secondary procedures. In our experience, pollicization provides the most rapid and effective means of restoration of thumb function in the severe pediatric hand burn with multiple digit loss.     

Auricular reconstruction: indications for autogenous and prosthetic techniques

Learning Objectives: After studying this article, the participant should be able to: 1. Describe the alternatives for auricular reconstruction. 2. Discuss the pros and cons of autogenous reconstruction of total or subtotal auricular defects. 3. Enumerate the indications for prosthetic reconstruction of total or subtotal auricular defects. 4. Understand the complexity of and the expertise required for prosthetic reconstruction of auricular defects.The indications for autogenous auricular reconstruction versus prosthetic reconstruction with osseointegrated implant-retained prostheses were outlined in Plastic and Reconstructive Surgery in 1994 by Wilkes et al. of Canada, but because of the relatively recent Food and Drug Administration approval (1995) of extraoral osseointegrated implants, these indications had not been examined by a surgical unit in the United States. The purpose of this article is to present an evolving algorithm based on an experience with 98 patients who underwent auricular reconstruction over a 10-year period. From this experience, the authors conclude that autogenous reconstruction is the procedure of choice in the majority of pediatric patients with microtia. Prosthetic reconstruction of the auricle is considered in such pediatric patients with congenital deformities for the following three relative indications: (1) failed autogenous reconstruction, (2) severe soft-tissue/skeletal hypoplasia, and/or (3) a low or unfavorable hairline. A fourth, and in our opinion the ideal, indication for prosthetic ear reconstruction is the acquired total or subtotal auricular defect, most often traumatic or ablative in origin, which is usually encountered in adults. Although prosthetic reconstruction requires surgical techniques that are less demanding than autogenous reconstruction, construction of the prosthesis is a time-consuming task requiring experience and expertise. Although autogenous reconstruction presents a technical challenge to the surgeon, it is the prosthetic reconstruction that requires lifelong attention and may be associated with late complications. This article reports the first American series of auricular reconstruction containing both autogenous and prosthetic methods by a single surgical team.     

Innervated radial thenar flap combined with radial forearm flap transfer for thumb reconstruction

A radial thenar flap combined with radial forearm flap was used for the reconstruction of the ipsilateral thumb in four patients. Vascular supply of the combined flap was based on the radial artery and extending the vascular pedicle to the superficial palmar branch of the radial artery. The flap was sensated by the palmar branch of the superficial radial nerve. The size of the flap averaged 15 x 5 cm and the innervated region of the thenar eminence was an area approximately 5 x 3 cm located over the proximal parts of the abductor pollicis brevis and opponens pollicis muscles. The flap was transferred as a free flap in three patients and as an advancement flap in one patient. The flaps survived completely without complications. Satisfactory restoration of sensation was achieved in the flap area, as shown by 6 mm of average moving two-point discrimination. This combined flap may be a feasible reconstructive option for large palmar defects of the fingers such as degloving injuries.
