The results of a specific type of prosthetic reconstruction of the knee (total replacement arthroplasty) after resection of a sarcoma of the proximal part of the tibia in sixteen patients were retrospectively reviewed. The diagnosis was stage-IIB osteogenic sarcoma in nine patients, stage-IIB malignant fibrous histiocytoma in three patients, and stage-IB sarcoma of various types in four patients. The length of tibial resection ranged from 100 to 257 millimeters. Of the eleven patients who were available for functional examination (mean duration of follow-up, sixty-three months), three patients had an excellent result, seven had a good result, and one had a fair result. Of the five patients who were not available for functional testing, one who was doing well was lost to follow-up at eighty months, one had died of metastases at sixteen months, and three had had a secondary amputation for infection or for loosening of the prosthesis.
In competitive athletes, stress fractures of the tibia, foot, and ankle are common and lead to considerable delay in return to play. Factors such as bone vascularity, training regimen, and equipment can increase the risk of stress fracture. Management is based on the fracture site. In some athletes, metabolic workup and medication are warranted. High-risk fractures, including those of the anterior tibial diaphysis, navicular, proximal fifth metatarsal, and medial malleolus, present management challenges and may require surgery, especially in high-level athletes who need to return to play quickly. Noninvasive treatment modalities such as pulsed ultrasound and extracorporeal shock wave therapy may have some benefit but require additional research.
The anterior cruciate ligament (ACL) is a thin piece of connective tissue in a human's knee that connects our upper leg bone (femur) to our lower leg bone (tibia). This helps our knee function efficiently. A dog also has tissue connecting their femur and tibia. However, in dogs this tissue is called the cranial cruciate ligament or CCL.
If a dog's ACL gets injured, the tibia will slide forward in relation to the femur. This forward sliding shift is called 'positive drawer sign' and leads to instability within the knee, which may cause damage to cartilage and surrounding bones, or osteoarthritis.
The next surgical option we'll look at for treating your dog's injured ACL is the tibial plateau levelling osteotomy (TPLO). This surgery is more complicated than ELSS surgery and aims to reduce tibial thrust without relying on the dog's ACL (CCL).
This surgery involves making a complete cut through the top of the tibia (tibial plateau), then rotating the tibial plateau in order to change its angle. Finally a metal plate is added to stabilize the cut bone as it heals. Over the course of several months, your dog's leg will gradually heal and strengthen.
Matrix-induced autologous chondrocyte implantation or MACI is a successful treatment option for symptomatic trochlea chondral defects following a suprapatellar approach for tibial intramedullary nailing placement.
The infrapatellar approach requires the knee joint to be flexed 90 degrees or greater, resulting in a higher risk of malalignment. In comparison, the suprapatellar approach involves a semi-extended position with the knee bent approximately 15 degrees [2]. This approach allows for better alignment of tibial fractures and a consequently higher rate of union [3]. It has been shown to decrease the risk of malalignment, and overall yield better functionality after recovery than the infrapatellar approach to IMN [4].
Suprapatellar IMN is commonly associated with anterior knee pain [9]. However, the true cause remains unknown. An ultrasound study found no anatomical differences of the patellar tendon when varying paratendinous or transtendinous approaches to IMN, suggesting that anterior knee pain is independent of the tibial IMN approach used [10].
When patients note ongoing patellofemoral knee pain following tibial fracture fixation with a suprapatellar tibial IMN approach, one should consider the presence of a chondral defect in the trochlea and note that this trochlear articular cartilage damage can be easily managed with the application of ACI.
Most dogs have a tibial plateau angle (TPA) between 20-30 degrees. Occasionally dogs will have an excessive tibial plateau angle (eTPA), which is an angle greater than 34 degrees. eTPA can be unilateral or bilateral and is most likely associated with a caudal deformity of the proximal tibia. Excessive stress on the CCL as a consequence of the altered conformation has been postulated as the mechanism of ligament injury.
Recognizing this abnormality before surgery with radiographs (lateral view of entire tibia) is important because the typical surgeries for CCL rupture may not be appropriate. The theory behind the Lateral Suture is to replace the CCL. If the CCL ruptured because of the excessive stress from the eTPA, then the Lateral Suture will likely fail as well. Therefore surgeries that level the tibia plateau are generally recommended for dogs with eTPA.
Sometimes the eTPA can be corrected with a TPLO or TTA alone. The tibial plateau, however, can be rotated only so far with a TPLO, and the tibial crest can be advanced only so far with a TTA. The current recommendations are to combine a TPLO with a cranial closing wedge osteotomy (CCWO) to achieve a level tibial plateau in dogs with eTPA. This procedure requires additional pre-operative planning and a has a complication rate approaching 25% rather than the traditional 10% with a TPLO alone.
When the anterior cruciate ligament is ruptured the femur tends to be pulled backwards and the tibia is forced forwards and relatively upwards. This is known as tibial thrust and it causes theinstability in the knee joint. The femur 'rolls backwards' down the top (plateau) of the tibia which is exacerbated by a tibial plateau that slopes backwards. Both complete rupture and partialtears prevent the dog taking full weight on the knee resulting in the dog becoming lame and the muscle on the front of the thigh becoming wasted.
Tibial plateau leveling is a technique that changes the slope of the tibial plateau (top of the shin bone that articulates with the thigh bone). This stops the femur 'rolling' back down the top ofthe tibia causing a mechanical lameness. The femur now rests in a more neutral position, with the tibial axis acting through the centre of the head of the femur. The net result is that whenthe dog stands on its knee the femur and tibia does not displace relative to each other and the dog is able to bear weight on the leg. Because tibial thrust has been abolished the injured ligamentdoes not need repairing. Any strain on a torn ligament is removed.
For the first two weeks, exercise must be very carefully limited. The surgery has basically created a (controlled) fracture that has to be allowed to heal. The isolated and rotated piece of boneis usually stable and will heal well but too much exercise too soon will compromise this. However, too much early exercise, which includes allowing the dog to stand upright on its hind legs topeer over walls, out of windows etc., risks preventing the bone from healing or even damaging the plate and screws. The movement will rock the tibial plateau that is held by the plate. This will haveseveral potentially catastrophic results. The bone may not heal and the screws may loosen allowing to tibial plateau to move causing the carefully measured slope to change. This causes the lamenessto return as the joint becomes unstable again. The result will be further major surgery. In more minor cases, too much strain on the leg will cause a sprain of the patellar ligament or even afracture of the tibial crest. This will heal in time without more surgery but will increase the time it takes for the dog to recover. A 30-60kg dog, as many of them are, can really test themetalwork!
Less than six minutes into his tenure with the Boston Celtics, forward Gordon Hayward suffered a gruesome lower leg injury, dislocating his ankle and fracturing his tibia. Players from around the league offered their thoughts and prayers on Twitter, including Oklahoma City Thunder forward Paul George, who suffered a severe leg injury of his own three years ago.
George suffered an open tibia-fibula fracture in his right leg during a Team USA showcase in August 2014, when his foot landed on the edge of the basket stanchion. He missed most of the following season, returning a little more than eight months later, but has been named an Eastern Conference All-Star in each of the two seasons since. He was traded to the Thunder from the Indiana Pacers this offseason.
In a 2013 UFC middleweight title fight, Chris Weidman blocked a kick from Silva, breaking the tibia and fibula in his left leg in the process. He won his first fight back in 2015 against Nick Diaz by unanimous decision, but the result was later overturned after Silva tested positive for two anabolic steroids. He lost his next two fights before defeating Derek Brunson in February.
Background: Residual equinus deformity in toddlers with a history of clubfoot can be managed with soft tissue release, provided there is no articular incongruity. Distal tibia osteotomy is a reasonable choice in mature patients with a flattened talus provided the growth plate is closed. Anterior distal tibia hemi-epiphysiodesis is an option for children with articular incongruity who have substantial growth remaining. The aim of this study is to evaluate radiographic and clinical outcomes of this method.
Methods: Fourteen clubfoot patients (20 ankles) with residual equinus deformity were treated between 2010-2015 with anterior distal tibial hemi-epiphysiodesis utilizing size appropriate modular plate and screw constructs. Patients were evaluated clinically and radiographically. Oxford Ankle Foot Questionnaire for Children (and caregivers) with supplemental questions were requested at most recent follow-up.
