Chest reconstruction: II. Regional reconstruction of chest wall wounds that do not affect respiratory function (axilla, posterolateral chest, and posterior trunk).

LEARNING OBJECTIVES: The reader of this review will develop knowledge and understanding of the following: 1. Indications for posterior trunk and axillary reconstruction. 2. The reconstructive requirements of posterior chest wall and axillary wounds. 3. Flaps for regional reconstruction of the torso and axilla. 4. Congenital posterior trunk deformities and their management. 5. The role of microvascular surgery in chest wall reconstruction. 6. The recent emphasis on the role of perforator flaps. 7. The relative advantages and disadvantages of muscle flaps versus perforator skin and fasciocutaneous flaps. BACKGROUND: Regional reconstructions of the axilla, posterolateral chest, and posterior trunk may prove difficult because of relative inaccessibility for pedicle flaps, exposure of prosthetic material, and loss of function. METHODS: Review of past and current medical literature, together with personal experience, has enabled development of this article. RESULTS: A host of regional muscle and musculocutaneous pedicle flaps are available from both the upper and lower limb girdle. These muscle flaps, however, come at the price of compromising donor motor function. This donor morbidity can be reduced either by segmentally splitting muscle flaps or by recourse to perforator artery flaps. Some areas may be difficult to reach, especially the upper and lower back in the midline. Occasionally, microvascular reconstruction is required. Tissue expansion has a limited role in these reconstructions but most notably is an aid to separation of conjoined twins. CONCLUSIONS: A variety of regional fasciocutaneous and musculocutaneous flaps are available to cover congenital or acquired defects of the posterior trunk and axilla. Use of perforator flaps has recently been popularized. One must be cognizant of possible functional deficits that may result when using regional muscle flaps both on ambulation and potential to power a manual wheelchair or use crutches.

Chest reconstruction: I. Anterior and anterolateral chest wall and wounds affecting respiratory function.

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Describe the indications for chest wall reconstruction. 2. Understand the function of the chest wall and implications for both reconstruction and the chest wall itself when components are missing or used for reconstruction. 3. List the reconstructive requirements of chest wall wounds. 4. Identify flaps for regional reconstruction of the chest wall. 5. Describe the role of microvascular surgery in chest wall reconstruction. BACKGROUND: Chest wall and mediastinum wounds may be life-threatening. They interfere with respiratory mechanics and may also be contaminated with exposed vital structures. Consideration is given to flap choice to restore function, resolve infection, and maintain suitable aesthetics. METHODS: Literature search as well as the authors' personal experience enabled preparation of this article. RESULTS: Where necessary, skeletal integrity must be restored, generally with prosthetic material, and then covered with well-vascularized soft tissue. "Living tissue" is required to help combat infection, buttress visceral repairs, and fill dead space. Soft-tissue deficiency must occasionally be augmented with large distant microvascular flaps. CONCLUSION: Flap reconstruction has reduced morbidity and mortality of these complex problems without undue donor-site impairment of respiratory and upper extremity function.

Non-malignant fibrosing tumors in the pediatric hand: a clinicopathologic case review.

Non-malignant fibrosing tumors in the pediatric hand or juvenile fibromatoses are clinically challenging because of their relatively infrequent occurrence and because of the variety of names associated with these diseases. We conducted a review of a personal case series of pediatric patients with these tumors and discuss here the more common histologic types and clinical characteristics of the disease spectrum in the context of the available published literature. All histologic samples were reviewed by a single pathologist. Infantile myofibromatosis, fibrous hamartoma of infancy, juvenile aponeurotic fibromatosis, palmar fibromatosis (Dupuytren's type), infantile digital fibromatosis (Reye's tumor), fibroma of the tendon sheath, and melorheostosis represent the encountered lesions.

Treatment of congenital upper extremity problems.

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Describe the terminology and classification of congenital hand anomalies. 2. Describe the incidence and embryogenesis of some common congenital hand anomalies. 3. Discuss the general principles and goals for treatment of congenital hand anomalies. 4. Describe the management of five of the more common congenital hand anomalies (syndactyly, short digits, thumb duplication, hypoplastic thumb, and radial dysplasia). SUMMARY: Congenital hand anomalies can cause substantial emotional and functional problems. This article reviews the etiology, classification, and management of some of the more common hand anomalies. A general approach to the patient and the goals of treatment are reviewed, as is the approach to five specific congenital hand anomalies: syndactyly, short digits, thumb duplication, hypoplastic thumb, and radial dysplasia.

Boomerang flap reconstruction for the breast.

The boomerang-shaped latissimus dorsi musculocutaneous flap for breast reconstruction offers a stable platform for breast reconstruction. It allows for maximal aesthetic results with minimal complications. The authors describe a skin paddle to obtain a larger volume than either the traditional elliptical skin paddle or the extended latissimus flap. There are three specific advantages to the boomerang design: large volume, conical shape (often lacking in the traditional skin paddle), and an acceptable donor scar. Thirty-eight flaps were performed. No reconstruction interfered with patient's ongoing oncological regimen. The most common complication was seroma, which is consistent with other latissimus reconstructions.
