Crossgates River Oaks Hospital in Brandon now provides specialized service in the area of microsurgery for the treatment of severe extremity trauma, hospital officials announced recently. At Crossgates River Oaks, plastic and reconstructive surgeons William Lineaweaver, MD, and Tanya Oswald, MD, bring years of experience and specialized surgical skills to treat complicated hand and extremity injuries.
“Lineaweaver and Oswald have successfully treated patients from across the state as well as the U.S. and international countries seeking replantation or reconstruction of extremities through the use of microsurgery,” said Allen Tyra, Crossgates River Oaks’ CEO.
Microsurgery is a specialized type of surgery that involves the use of an operating microscope. Microsurgery is performed when a patient’s hand or other body part becomes detached through a motor vehicle accident or other severe trauma or injury, including a saw or heavy equipment.
The techniques allow repair of critical small vessels and nerves as well as transplantation of tissue from other parts of the body to repair an injury.
Through the use of microsurgery, Lineaweaver and Oswald can reattach severed extremities, including hands, fingers, arms, legs and feet as well as facial structures, such as ears, lips and scalp. Following surgery and if needed, follow-up therapy, most patients can regain function of previously amputated or injured parts.
In addition to restoring function to amputated parts, the surgeons can transfer nerves to new locations to maximize function and achieve other positive results even when massive soft tissue injury has occurred. Treatment of other complicated wounds, including severe burns, is also provided at Crossgates River Oaks and at the Joseph M. Still Burn & Reconstruction Center at Crossgates River Oaks Hospital.
Tyra added that an increasing number of patients are being transported to Crossgates River Oaks from other areas to receive treatment by the surgeons. Lineaweaver and Oswald are part of an elite group of Mississippi surgeons trained in the complex microsurgical technique.
“We are proud of the fact that patients from other areas of Mississippi and in many cases, areas far beyond our state, travel to Crossgates River Oaks to receive the treatment and accompanying surgery necessary to repair severe hand and extremities trauma,” Tyra said. “But despite the impressive statistics, Dr. Lineaweaver and Dr. Oswald are caring professionals who provide each and every one of our patients with ongoing personalized attention from the moment they arrive at our hospital.”
Lineaweaver is a board-certified plastic surgeon with an additional certification in hand surgery. He has over 20 years of surgery experience in the areas of plastic and reconstructive surgery, hand surgery, microsurgical replantation and flap transplantation. He is medical director of the Joseph M. Still Burn and Reconstruction Center at Crossgates River Oaks Hospital, Mississippi’s only inpatient burn center.
Oswald also received certification by the American Board of Plastic Surgery. During her surgery training, she was named a Hand and Microvascular Fellow at Washington University in St. Louis and a Microsurgery and Complex Reconstruction Fellow at University of Mississippi Medical Center.
