Ola Therapeutic Rehabilitation McKendree University Dr. Hankins 2 Abstract This paper gives an injury scenario for a tibia/fibula fracture and how the athlete will recover from such an injury. With this injury the athlete has multiple surgery choices and could have done some things to further prevent the injury from happening. This paper outlines the first six weeks of the athlete’s rehabilitation and will give an idea of what it is like to go through such a program. The reader will also learn the anatomy of the lower leg. For example, where the tibialis anterior attaches and what you use it for. The occurrence of tibia, fibula and ankle fractures in the United States per year is 492,000; according to the National Center for Health Statistics (Praemer, Furner, & Rice, 1992). Of 339 patients, admitted to Trondheim Regional and University Hospital, 11 of them suffered tibial fractures, about 3% (Sahlin, 1989). These accidents were a direct result of downhill skiing. 3 INTRODUCTION History of Downhill Skiing Downhill skiing has been around for hundreds of years but did not make it to America until the early 1900’s. The winter games in 1924 had five original games and two of them were Nordic combined and ski jumping and in 1932 they featured cross country skiing. People living in the Telemark region of Norway are credited turning skis into a sport in the 1700’s. They also invented the Christie and Telemark turns to control downhill descent speed. Downhill skiing is one of the variations of alpine skiing and the names are usually used interchangeably. The rules were established in 1921 by Sir Arnold Lunn for the British National Ski Championships. Downhill is one of the more dangerous events because of the great speed athletes travel at not to mention having to turn multiple times and navigate jumps and hills. Competing in downhill requires great strength and expertise to navigate at high speeds. Injuries in Downhill Skiing By far the most common injury in downhill skiing involves injury to the knee ligaments. Knee injuries account for thirty to forty percent of all injuries. Of that thirty to forty percent medial collateral ligament (MCL) tears comprise twenty to twenty five percent and the other ten to fifteen percent are anterior cruciate ligament (ACL) tears. MCL tears usually happen in the “snowplow” position. This position is used for beginners and is basically just rotation of the hip 4 joints externally. A valgus load is applied to the knees as a result of a fall, crossing skis or widening of the stance. There are several mechanisms of injury for ACL tears but the most common is the “phantom foot” fall. This can happen when the skier’s uphill arm is back, the skier is off balance to the rear, the hips are below the knees, bodyweight is carried on the inside edge of downhill ski tail, the uphill ski is unweighted or the upper body is facing the downhill ski. The more of these positions present; the more likely the athlete is to get an ACL injury. Medial meniscus injuries account for about five to ten percent of all injuries and a fracture of the tibial plateau is rare and only makes up one percent of the total. If an athlete tears the ACL, MCL, and medial meniscus it is referred to as the “Triad of Donohue” or the “Terrible Triad”. Upper extremity injuries are usually either a dislocated shoulder, fractured thumb, injured thumb or an injured wrist. Most skiing deaths are caused because of a head injury after a high-speed collision. Head injuries are mainly concussions but cervical fractures do occur and should always be suspected. With all the risk and skill needed to be a good downhill skier one must be in tip top shape and always aware of the variable terrain. Other injuries of the lower extremities may also occur such as: fractures of the tibia, fibula, ankle and foot. INJURY Injury Scenario and Mechanism of Injury Zachary Wreath, a world class downhill skier, was expertly navigating his gates when he hit an unexpected jump on the course. Upon landing, his ski caught in the snow causing his left, lower leg to bend awkwardly. The force applied by his landing snapped both his tibia and fibula causing massive amounts of pain. Paramedics rushed to the scene and quickly splinted Zachary’s leg and air lifted him to the nearest emergency care center. X-rays showed his bones had broken 5 in an oblique pattern resulting from the direction of the shear force applied to his leg. While this injury is fairly uncommon, the extreme stress applied by the awkward landing was enough to snap both bones. Zach would need surgery to fix the fracture in his leg. Predisposing Factors & Signs and Symptoms Some factors that may cause a fracture of the tibia and/or fibula are direct and indirect trauma. Direct trauma would indicate a blunt force to the fractured area; while indirect trauma would occur from a sharp twist that caused a spiral fracture in the bones. The signs and symptoms of such a fracture includes: deformity at the injury site, discoloration, increased temperature, swelling and a positive squeeze and percussion test. If these tests and prerequisites are met then the athlete may require surgery to fix the break. SURGICAL OPTIONS Casting According to Murthy and Hoppenfeld (2000) in order to be casted for a tibia/fibula fracture the stability must include displacement fifty percent or less of the tibial width and shortening of one centimeter or less. Also, the alignment should return rotation and angulation to within five to ten degrees of the uninjured tibia, in all planes. The biomechanics of a cast are stress-sharing and the mode of bone healing is secondary. Intramedullary Rod The biomechanics of this technique can be either stress-sharing or stress-shielding depending on whether the nails are dynamically interlocked or statically interlocked. The mode of bone healing in this option is also secondary. “This treatment is the gold standard for unstable and segmental tibial fractures or those that cannot be adequately aligned and immobilized by non-operative means” (Taylor, 2000, p. 367). It also allows for early mobilization of the patient 6 along with knee motion returning sooner. For this surgery process an intramedullary rod will be run down the intramedullary shaft of the tibia with a drill. After the rod has been placed it is secured with screws that run through the width of the bone. External Fixator This method is used more often in open fractures resulting in significant bone loss and treatment should be considered provisional until the skin graft can achieve soft tissue coverage. It is also usually followed up with the placement of an intramedullary rod. Biomechanics are considered stress-sharing and the mode of bone healing is secondary. Open Reduction and Internal Fixation with Plates For this surgical option, the biomechanics are stress-shielding and the mode of bone growth is actually primary. It is not commonly done in this area because of the demands it withholds. There must be scraping of the periosteum and violation of the soft tissues to make room for the plates and to allow for proper healing. This technique is usually used on nonunion fractures for these reasons. ANATOMY Dorsiflexors The tibialis anterior originates on the lateral condyle and upper two thirds of the lateral surface of the body of the tibia, interosseous membrane, and the deep crural fascia while inserting at the base of the first metatarsal and the medial and plantar surfaces of the medial cuneiform bone. It collects nerve supply from the deep peroneal nerve and the nerve roots at located at L4, L5, and S1. The extensor hallicus longus originates on the medial surface of the body of the fibula and the interosseous membrane and inserts into the base of the distal phalanx of the great toe. It is supplied neural activity by the deep peroneal nerve and the nerve roots are 7 L4, L5, and S1 (Reese 2005). The extensor digitorum longus gains neural supply from the deep peroneal nerve and also has nerve roots at L4, L5, and S1. It originates at the lateral tibial condyle, anterior surface of the body of the fibula and interosseous membrane and it inserts at the dorsum of the middle and distal phalanges of the second, third, fourth and fifth toes (Reese 2005). Plantarflexors The gastrocnemius has two heads; the medial head originates on the medial condyle and adjacent popliteal surface of the femur and the lateral head originates on the lateral condyle of the femur. Both heads insert via the tendo calcaneus (Achilles’ Tendon) into the posterior surface of the calcaneus. The nerve supply is the tibial nerve and the roots stem from S1 and S2. The soleus gains nerve supply from the tibial nerve also and the roots stem from S1 and S2 as well. It originates on the posterior surface of the head and proximal one third of the body of the fibula, soleal line and middle one third of the medial border of the tibia. Insertion occurs via the Achilles’ tendon into the posterior surface of the calcaneus (Reese 2005). The flexor hallicus longus is supplied neural activity by the tibial nerve and has nerve roots at L5 and S1. It originates on the posterior aspect of the body of the fibula, and the interosseous membrane and it inserts onto the base of the distal phalanx of the great toe. The flexor digitorum longus originates on the posterior aspect of the body of the tibia and inserts into the base of the distal phalanges of the second, third, fourth, and fifth toes (Reese 2005). Inverters and Everters The tibialis posterior has a nerve supply from the tibial nerve and nerve roots at L5 and S1. It originates on the posterior aspect of the interosseous membrane, posterior surface of the body of the tibia, and proximal two thirds of the medial surface of the fibula and it inserts at the 8 tuberosity of the navicular bone, all three cuneiform bones, and bases of the second, third and fourth metatarsals (Reese 2005). The tibialis anterior originates on the lateral condyle and upper two thirds of the lateral surface of the body of the tibia, interosseous membrane, and the deep crural fascia while inserting at the base of the first metatarsal and the medial and plantar surfaces of the medial cuneiform bone. It collects nerve supply from the deep peroneal nerve and the nerve roots at located at L4, L5, and S1. The peroneus longus originates on the head and upper two thirds of the lateral surface of the fibula and inserts on the base of the first metatarsal, and the lateral aspect of the medial cuneiform. The superficial peroneal nerve supplies the muscle and the nerve roots are located at L4, L5, and S1. The peroneus brevis is also supplied by the superficial peroneal nerve and L4, L5, and S1 are the nerve roots. It originates on the distal two thirds of the lateral surface of the fibula and inserts at the tuberosity of the fifth metatarsal (Reese 2005).
