PHYSICIANS ON THE FRONT LINE Figure 1 - Preoperative and postoperative radiographs of ankle replacement in a retired Airborne infantryman. Figure 2 - Postoperative radiograph following cavovarus foot reconstruction and fifth metatarsal base screw fixation in a 50-year-old University ROTC instructor. I completed Airborne School in 1979, making the required five static line parachute jumps to earn my “Jump Wings.” One of my recent retired Army patients was an old paratrooper who developed ankle arthritis resulting from fractures sustained parachuting in the Airborne Infantry. He had made hundreds of parachute jumps with heavy equipment strapped to his body and was also qualified as a Jumpmaster. A Jumpmaster directs paratroopers to jump out of the plane at the correct time to reach the drop zone. He also “en- courages” soldiers who have second thoughts to leave the aircraft. My patient was a likeable colorful character who proudly still wore his Airborne Wings on his hat. I was able to perform a successful ankle replacement and relieve his ankle pain (see Figure 1). He is still pending bilateral knee replacements. His physical sacrifice continues into his retirement. soldier is Achilles tendon rupture. This injury is most common in the third and fourth decade and usually occurs after stepping in a hole or while playing basketball. Standard open repair can be achieved through a relatively small incision, although minimal incision techniques are also successful. Outcomes from treatment of this Achilles tendon rupture are excellent. Wartime limb injuries can be devastating and may lead to am- putation. With improved body armor and helmets, soldiers may survive blast injuries only to be left with one or more amputated limbs. Amputees can have problems with phantom pain, prosthesis fitting and stump neuromas. I recently treated a Vietnam veteran who had ongoing problems with pain in his above the knee am- putation stump. He was unable to wear his prosthesis due to pain. MRI documented a neuroma of the sciatic nerve. I was able to resect the painful neuroma, which allowed him to continue use of his prosthesis. Most of my active duty patients have ankle injuries from recur- rent ankle sprains or fractures sustained while running on uneven ground. Talar osteochondritis dessicans lesions and painful ankle loose bodies are easily treated with ankle arthroscopy. Recurrent lateral ankle inversion instability requires lateral ankle reconstruc- tion, usually with allograft tendon, to anatomically reconstruct the anterior talofibular and calcaneofibular ligaments through drill holes in the talus and fibula. Another common injury in the active duty Some patients are born with a foot structure that predisposes them to injury. Most obvious pre-existing conditions are grounds for denial of entrance into military service. Some subtle deformities may be overlooked or waived. A 50-year-old retired Army Sergeant First Class with 20 years active duty experience saw me for lateral foot pain. He had a history of two previous foot surgeries. He had a cavovarus (high arched foot) and walked on the lateral border of his foot. His abnormal foot structure had caused chronic tears of his peroneal tendons and a fifth metatarsal base stress fracture. He had failed multiple attempts of physical therapy and orthotics. This patient required triple arthrodesis and first metatarsal base closing wedge osteotomy for correction of his deformity, screw fixation of the fifth metatarsal, and repair of peroneal tendons (see Figure 2). Recovery from this extensive surgery required three months of nonweight-bearing. Total recovery will take one year. He is now five months postoperative and is back at his job as a university ROTC instructor. As Veterans’ Day again is celebrated this month, let us take time to acknowledge the many sacrifices of our active duty personnel and retirees. If you are fortunate enough to treat them as patients, remember that their service is what keeps our way of life safe and secure.
