Microsurgery for lower extremity injuries

SUMMARY: An entire generation of orthopaedic and plastic surgeons has been indelibly and perhaps overwhelmingly influenced by the introduction of microvascular technology to the fields of limb salvage and musculoskeletal reconstruction. Free-tissue transfer using microsurgical techniques has become a valuable method for the salvage of lower extremities after trauma. The goals of free flaps are both soft-tissue coverage and improvement of the functional outcome. The flap selection criteria for lower extremity reconstruction are based on the wound surface area, the type of tissue deficiency, length of the pedicle, volume of deficient tissue components and donor site morbidity. Composite flaps represent the state-of-the-art for reconstructive microsurgery, providing more than one function. Although many different treatment protocols have been proposed, they all highlight the importance of early tissue coverage with bone management performed in a later stage.     

Ultrasonography of the lower extremity

Ultrasonography is a useful imaging tool for various soft tissue and joint pathologies affecting the lower extremity. This article reviews the normal sonographic appearance of muscles, tendons, ligaments, nerves, bone, and cartilage. The ultrasound imaging appearance of various pathologic conditions affecting the hip, thigh, knee, lower leg, ankle,and foot are illustrated. The advantages of ultrasonography are highlighted.     

Liposarcoma of the lower extremity

Twenty patients with primary liposarcoma of the lower extremity were treated over a 25-year period. The adequacy of the initial surgical procedure and histological grade of malignancy both influenced survival rates. In addition local recurrence was noted only in patients who had undergone "inadequate" initial excision. Inguinal lymph nodes were uninvolved by tumor in all cases. In general, patients with liposarcomas of myxoid and/or round cell type survived for long periods of time. However, even patients with myxoid lesions occasionally exhibited evidence of early blood-borne metastases. This study suggests an important relationship between an inadequate primary resection, local recurrence, and eventual retroperitoneal spread. In the majority of cases, this may have resulted from failure to control the primary distal extremity tumor, with subsequent contiguous spread of metastases into the ipsilateral retroperitoneal space. If feasible, radical soft part resection should be performed as the primary surgical therapy of these neoplasms. Tumors contiguous to the knee or ankle joint should be treated by primary amputation. Failure to control local disease may result in blood-borne dissemination or local spread along musculoaponeurotic planes to involve proximal groin or retroperitoneal space.     

Kinematics of the lower extremity

Range of motion of the lower extremity joints from the hip to the digits will be discussed including both active and passive axis of motion and their planes of motion. The author believes that the interpretation of these ranges of motion is essential in order to properly diagnose and to execute a treatment plan.
