1/209. Recognition and management of Tillaux fractures in adolescents.Tillaux fractures are relatively uncommon Salter Harris III fractures of the tibia. The importance of recognizing this fracture is that a residual deformity in the joint surface can lead to premature degenerative arthritis. For this reason, it is important that accurate imaging to assess the congruity of the joint, as well as adequate reduction, is obtained. These fractures can occur in adolescents in the 18-month period during which the distal tibial epiphysis is closing. These injuries occur either by lateral rotation of the foot or by medial rotation of the leg on the fixed foot. Closed reduction is sufficient in most cases; however, if a gap of > or = 2 mm of the articular surface remains, open reduction is usually required to adequately reduce the articular surface. Orthopedic injuries are one of the most common reasons children are brought to the emergency department (ED). Most of these injuries are easily managed by splinting, with outpatient orthopedic follow-up. However, certain fractures need closer evaluation and immediate consultation with an orthopedic surgeon. One relatively uncommon fracture that needs special attention is the Tillaux fracture. Paul Jules Tillaux first described this particular fracture in 1892. He performed experiments on cadavers and found that stress to the anterior inferior tibiofibular ligament could lead to this type of avulsion fracture, which today is termed the Tillaux fracture. The distal tibial epiphysis is involved, and the mechanism usually is forced external rotation of the foot in a 12- to 14-year-old adolescent. This fracture only occurs during a certain time of adolescence, owing to the differential growth rate of the epiphysis, and only under certain circumstances. The fracture is of great importance because it involves a major weight-bearing articular surface. A residual deformity of the joint surface can lead to premature degenerative arthritis. We present a patient with a Tillaux fracture to elaborate on the mechanism of injury and to summarize the importance of its recognition and imaging and treatment options.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
2/209. Percutaneous autologous bone marrow grafting on the site of tibial delayed union.Six months after injury, 150 mL of autogenous bone marrow was applied percutaneously at the site of delayed union to stimulate the healing of a tibial delayed union fracture in a 44 year-old man. Five months following the procedure, the fracture gaps and bone defects were completely filled with callus, the external fixator was removed, and the patient started using normal leg loading.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
3/209. Acute compartment syndrome complicating a distal tibial physeal fracture in a neonate.This case report of a neonate who developed an acute compartment syndrome secondary to a minimally displaced distal tibial physeal injury represents the youngest patient to be reported with such a condition. After undergoing emergency four-compartment decompression fasciotomies, the 4-week-old child had a return of normal neuromuscular function and anatomic remodeling of the fracture. It is difficult to diagnose compartment syndrome in a neonate. The patient can neither give a history, nor follow commands to cooperate with the exam. The physician must rely primarily on the physical examination; however, the quantitative measurement of intracompartmental pressure can corroborate the diagnosis of compartment syndrome. We have found using a monometer to measure intracompartmental pressure to be helpful in conjunction with a physical exam when evaluating a neonate suspected of having a compartment syndrome.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
4/209. Transcranial doppler detection of fat emboli.BACKGROUND AND PURPOSE: The fat embolism syndrome (FES) is characterized by the simultaneous occurrence of pulmonary and neurological symptoms as well as skin and mucosal petechiae in the setting of long-bone fractures or their surgical repair. Its pathophysiology is poorly understood, and effective treatments are lacking. We present 5 patients with long-bone fractures in whom in vivo microembolism was detected by transcranial Doppler. methods: Five patients with long-bone fractures were monitored with transcranial Doppler for microembolic signals (MESs) after trauma. Two patients also had intraoperative monitoring. A TC-2020 instrument equipped with MES detection software was used. Detected signals were saved for subsequent review. Selected signals satisfied criteria defined previously and were categorized as large or small. RESULTS: Cerebral microembolism was detected in all 5 patients and was transient, resolving within 4 days of injury. Intraoperative monitoring revealed an increase in MESs during intramedullary nail insertion. The characteristics of MESs after injury varied among patients, with large signals being more frequent in the only patient with a patent foramen ovale. CONCLUSIONS: Cerebral microembolism after long-bone fractures can be detected in vivo and monitored over time. These findings may have potential diagnostic and therapeutic implications.- - - - - - - - - - ranking = 2keywords = injury (Clic here for more details about this article) |
5/209. Combined talar body and tibial plafond fracture: a case report.We report a case of a crush fracture of the body of the talus associated with an anterior tibial plafond fracture. This injury is a rare variant of talar body fracture which merits special attention. The bony injury in this type of fracture is associated with multiple loose fragments involving both weightbearing surfaces of the ankle joint. After appropriate imaging to allow preoperative planning, we utilized a two-incision approach which was necessary to achieve adequate exposure and fixation. We used basic fracture management principles to deal with a previously undocumented fracture pattern.- - - - - - - - - - ranking = 2keywords = injury (Clic here for more details about this article) |
6/209. The application of arthroscopic principles to bone grafting of delayed union of long bone fractures.The purpose of this study was to explore the potential of applying arthroscopic techniques to autogenous bone grafting of long bone fracture delayed union. There were 9 patients in this initial series, including 4 patients (average age, 37 years) with humeral lesions and 5 patients (average age, 25 years) with tibial fractures. There were 6 men and 3 women. Techniques customarily employed in arthroscopy were used to visualize, expose, and deliver the onlay cancellous bone grafts. Bony union occurred in all but 1 patient in an average of 4 months. This patient had a fibrous union and sustained a reinjury that led to successful repeat open bone graft surgery. The arthroscopic approach for bone grafting of certain long bone delayed union appears to be a safe and effective procedure. The procedure is best suited for patients with mechanically stabilized fragments, and it lends itself to those with overlying skin or soft tissue compromise. There are some relative contraindications: grossly unstable fragments, severe malunion, and/or infection.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
7/209. Minimally invasive plate osteosynthesis of distal fractures of the tibia.Minimally invasive plate osteosynthesis of distal tibial fractures is technically feasible and may be advantageous in that it minimizes soft tissue compromise and devascularization of the fracture fragments. The technique involves open reduction and internal fixation of the associated fibular fracture when present, followed by temporary external fixation of the tibia until swelling has resolved. Subsequent limited, but open reduction and internal fixation of the articular fragments when displaced followed by minimally invasive plate osteosynthesis of the tibia utilizing precontoured tubular plates and percutaneously placed cortical screws is performed. The semitubular plate was chosen because it adapts more easily to the bone contours than the stiffer small fragment LC-DCP does. Twenty patients (age 25-59 years) with unstable intraarticular or open extraarticular fractures have been treated including 12 A-type, 1 B-type and 7 C-type fractures according to the AO classification. Two fractures were open (both Gustilo Type I). Closed soft tissue injury was graded according to Tscherne with 3 type C0, 7 type C1, 7 type C2 and 1 type C3. All fractures healed without the need for a second operation. time to full weight-bearing averaged 10.7 weeks (range 8-16 weeks). Two fractures healed with > 5 degrees varus alignment and 2 fractures healed with > 10 degrees recurvatum. No patient had a deep infection. The average range of motion in the ankle for dorsiflexion was 14 degrees (range 0-30 degrees) and plantar flexion averaged 42 degrees (range 20-50 degrees). With longer follow-up and a larger number of patients, the authors feel confident that the minimally invasive technique for plate osteosynthesis for the treatment of distal tibial fractures will prove to be a feasible and worthwhile method of stabilization while avoiding the severe complications associated with the more standard methods of internal or external fixation of those fractures.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |

9/209. Reconstruction of a tibial defect with microvascular transfer of a previously fractured fibula.A 43-year-old man sustained severe injuries to his lower limbs with extensive soft-tissue damage and bilateral tibial-fibular fractures. Acutely, the patient underwent external fixation and a free latissimus dorsi flap for soft-tissue coverage of the left leg. However, the tibia had a nonviable butterfly fragment that left a 7-cm defect after debridement. Subsequently, the contralateral fractured fibula was used as a bridging vascularized graft for this tibial defect. The transfer of a fibula containing the zone of injury from a previous high-energy fracture has not been reported. This case demonstrates the successful microvascular transfer of a previously fractured fibula for the repair of a contralateral tibial bony defect.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
10/209. achilles tendon rupture associated with ankle fracture.The case of a 40-year-old man who sustained a medial malleolar fracture with extension of the fracture into the tibial plafond is discussed. Before surgery, the physical examination revealed an achilles tendon rupture. Surgical treatment to repair the bone and tendon injury was performed. achilles tendon rupture is not an uncommon injury, but it is rarely associated with a fracture. When a fracture is present, the achilles tendon injury can be overlooked, which may result in a delay of treatment or residual morbidity.- - - - - - - - - - ranking = 3keywords = injury (Clic here for more details about this article) |
