    ABSTRACT: Posterior wall fracture is the most common acetabular fracture. Comminuted fractures with an impacted segment represent a subtype of this injury. The subchondral bone of the articular zone is compressed and causes a bone defect. The impacted fragment should be isolated, mobilized, and then reduced. A bone graft should be used to fill the gap. The other fragments are fixed following the reduction of the impacted segment. Ten patients with comminuted fractures and impacted segments with bone defects were enrolled in our study, from January 2010 to July 2012. Autogenous bone grafts from the greater trochanter were used to fill the gap in all patients. The reduction was achieved through the insertion of the graft above the impacted fracture, and plate fixation was performed subsequently. Merle d'Aubigne and Postel scoring, modified by Matta, was applied to evaluate the patients during follow-up. The mean follow-up was 12 months. The clinical results included one "excellent", four "very good", four "good" and one "poor". Pain in the zone of graft harvesting was not detected in any patient. Femoral head necrosis was observed in one case. No other severe complications were detected. Using an autogenous bone graft to fill the bone defect supplies excellent mechanical stability without any severe complications at the donor site. This surgical technique seems to be effective and safe in treating a comminuted fracture of the posterior wall in association with an impacted segment. Level IV.

    ABSTRACT: Indications and techniques of locked plate fixation for the treatment of challenging fractures continue to evolve. As design variant of classic locked plates, the polyaxial locked plate has the ability to alter the screw angle and thereby, enhance fracture fixation. The aim of this observational study was to evaluate clinical and radiographic results in 89 patients with 90 fractures of the distal femur treated, between June 2006 and November 2011, with such a polyaxial locked plating system (Polyax™ Locked Plating System, DePuy, Warsaw, IN, USA). Seventy-seven fractures formed the report of this study. These cases were followed up until complete fracture healing or for a mean time of 77 weeks. At the time of last follow-up, 58 of 77 fractures (75.3 %) progressed to union without complication and radiographic healing occurred at a mean time of 16.3 weeks. Complications occurred in ten fractures that did not affect the healing and in nine fractures that showed delayed or non-union. The mean American Knee Society Score at the time of final follow-up was 83 for the Knee Score and 71.1 for the Functional Score. In conclusion, there is a high union rate for complex distal femoral fractures associated with a good clinical outcome in this series.

    ABSTRACT: Bleeding associated with pelvic fracture mostly comes from the pre-sacral and lumbar venous plexus, or directly from the fracture site. Bleeding as a consequence of arterial lesion is less common (15-20%), and that resulting from lesion of the external iliac artery (EIA) is extremely rare. The mortality rate associated with iliac artery injury ranges from 38% to 72%. Total body CT-scan with contrast medium, angiography or packing can be performed when there is arterial injury. In some cases, embolisation can stop bleeding; however, when there is involvement of the aorta, common iliac artery or EIA, immediate surgery is mandatory. The aim of this study was to report our experience of pelvic fractures associated with EIA lesion. Six patients with pelvic fracture and associated rupture of the EIA have been observed at our unit from 2004 to 2009. According to Tile classification there were three cases of type C and two cases of type B fracture. One case was a two-column acetabular fracture. Angiography was performed in all cases. Three patients died on the day of trauma: two after angiography, and one after surgery of vascular repair. Three patients survived: two underwent a hemipelvectomy, and one underwent hip disarticulation. Haemodynamic instability in patients with pelvic ring fracture is usually because of venous bleeding from the pre-sacral and lumbar plexus, or from the fracture site. Arterial injury is present in around 20% of cases. EIA lesions require immediate surgical treatment to restore blood flow. Depending on the type of injury, vascular surgery can be associated with pelvic fracture stabilisation. Pelvic ring fracture associated with an EIA lesion is extremely rare, with few cases reported in the literature. Angiography is used for diagnosis, and immediate surgical treatment is required to restore blood flow. Associated injuries and open fracture can lead to fatal complications or amputation. Rates of mortality and severe disability are extremely high.

    ABSTRACT: Multifocal humeral fractures are extremely rare. These may affect the neck and the shaft, the shaft alone, or the diaphysis and the distal humerus. There is no classification of these fractures in the literature. From 2004 to 2010, 717 patients with humeral fracture were treated surgically at our department. Thirty-five patients presented with an associated fracture of the proximal and diaphyseal humerus: synthesis was performed with plate and screws in 34 patients, and the remaining patient had an open fracture that was treated with an external fixator. Mean follow-up was 3 years and 3 months. A classification is proposed in which type A fractures are those affecting the proximal and the humeral shaft, type B the diaphysis alone, and type C the diaphysis in association with the distal humerus. Type A fractures are then divided into three subgroups: A-I, undisplaced fracture of the proximal humerus and displaced shaft fracture; A-II: displaced fracture of the proximal and humeral shaft; and A-III: multifragmentary fracture affecting the proximal humerus and extending to the diaphysis. Multifocal humeral fractures are very rare and little described in the literature, both for classification and treatment. The AO classification describes bifocal fracture of the humeral diaphysis, type B and C. The classification suggested in this article mainly concerns fractures involving the proximal and humeral shaft. A simple classification of multifocal fractures is suggested to help the surgeon choose the most suitable type of synthesis for surgical treatment.

    ABSTRACT: Fractures of the pelvis in pediatric population are extremely rare. Children with complex pelvic fractures are most often pedestrians who have been struck by a motor vehicle. Head injuries are the main cause of death, unlike the adult, where severe hemorrhages are common and contribute to mortality. Long-term follow-up studies have reported significant residual morbidity in children's pelvic fractures treated non-operatively. The aim of this study is to analyze our cases in order to evaluate the final outcome and to suggest the surgical indications for the management of this kind of injuries. From January 2000 to July 2011, eight pediatric patients were surgically treated for pelvic ring fractures in our department. The functional result at follow-up was evaluated using the functional independence measure (FIM). In most cases the clinical outcome was good with functional recovery of the hip and complete resumption of physical activity. The mean FIM score was 125.3. One patient underwent permanent colostomy for perineal lacerations, one case showed a slight scoliosis at follow-up, and one patient showed the early fusion of the triradiate cartilage. One patient presented a deep thrombosis of the common femoral vein. Fractures of the pelvic ring should be carefully assessed by radiographs and CT scan. The centralization of these young patients is important to get the experience and ensure the proper treatment. A correct indication for surgery may prevent or limit the consequences of these complex fractures.

    ABSTRACT: Surgical treatment of a unusual acetabular fracture is described. This fracture was characterized by impaction and breaking down of the posterior articular surface and comminution of lamina quadrilatera lower portion, without cortical fracture of both columns. The fracture was treated surgically through the Kocher-Langenbeck approach. A small hole was created in the acetabulum posterior wall, the impacted fragment was reduced, and the bone defect was filled with autologous bone from the greater trochanter. A plate was shaped in order to fix both bone graft and fractured fragment.

    ABSTRACT: Acetabular fractures are often associated with dislocation of the femoral head. When the dislocation is reduced, > or = 1 fragments may remain inside the joint, especially in posterior dislocation. In this kind of dislocation, the fracture of the posterior wall of the acetabulum may be comminuted. The fragments attached to the joint capsule or free may remain between the femoral head and the acetabulum. During reduction, these fragments are dragged inside the joint. The presence of the fragments in the hip joint may prevent complete reduction of the dislocation. Surgery should be performed early to reduce the risk of aseptic necrosis of the femoral head. Sometimes the fragments derive from a fracture of the femoral head without involving the posterior wall. Fragments are difficult to detect by conventional radiography; therefore, computed tomography scans are always indicated in fracture-dislocations pre- and postoperatively to check that all intra-articular fragments have been removed and the fracture has been reduced. We observed 373 cases of acetabular fracture between January 1, 1997 and December 31, 2007. One hundred twenty-seven cases presented a dislocation: 5 anterior, 13 central, and 109 posterior. In 45 cases, after reduction of the dislocation, 2 anterior and 43 posterior intra-articular fragments were observed. Removing a loose body inside the joint is always necessary because movement causes damage of the cartilage and therefore an early arthritis. The strategy to remove and the approach differs according to the kind of dislocation observed.

    ABSTRACT: Fractures of the acetabulum on the horizontal plane include transverse fracture, transverse with anterior or posterior wall, “T” transverse. These fractures, usually associated with a dislocation of the femoral head, present a rotatory component that must be reduced with special clamps. Reduction is complex and requires a precise preoperatory planning and great surgical experience

    ABSTRACT: Femoral neck fractures are progressively increasing, due to higher survival rates, particularly among the female population. The gamma nail was created to treat intertrochanteric fracture types 31-A1, 31-A2 and 31-A3 and in some cases basicervical fractures of type 31-B2-1. Complications can be classified as intraoperative and postoperative. The intraoperative might be related to the nail's introduction site, lag and distal locking screw positions. Postoperative complications depend mostly on an incorrect surgical technique, which can lead to an inaccurate nail position and consequent implant failure. We rarely observe failures caused by severe bone osteoporosis.

    ABSTRACT: A series of 179 closed femoral fractures treated by static interlocking nailing (Grosse-Kempf nail) was reviewed to evaluate the effect of dynamization on the time to bony union. In 75 patients, dynamization was performed whereas in 104 the implant was left static. Union occurred in 178 patients. We observed one infection. Time to union was significantly shorter in the static group (103 days) compared to the dynamized group (126 days).

    ABSTRACT: Fractures of the distal fourth of tibia are difficult to treat because of the possible involvement of the joint, the comminution of the fragments, the local skin conditions and the surgical method required. There are many methods of osteosynthesis, and these range from external fixation to use of a plate to combined methods. Intramedullary nailing is generally not indicated in the treatment of such fractures, but if the correct technical procedure is used, indications may be widened, and the method may even be used in cases such as these. It is necessary to saw the tip of the nail so that the distal holes go beyond the fracture line. A total of 30 cases of fracture of the distal fourth of the tibia treated by Grosse-Kempf nailing sawed distally are reported.

    ABSTRACT: Nonunion of the subtrochanteric region is usually secondary to incorrect surgical treatment. The main cause of failed osteosynthesis is related to interruption of the medial cortex of the femur. Either a closed method, with intramedullary nailing, or an open method, using cortical osteosynthesis and opposing bone graft, may be used to treat the pathology. Surgery differs depending on the instrumentation used for the initial treatment of the fracture. A total of 8 cases of intra- and subtrochanteric nonunion with intramedullary nailing and cortical osteosynthesis are reported.

    ABSTRACT: Conjoined fracture-dislocation of the elbow were first described by Marotte in 1982. In this study, a total of 41 patients treated between 1975 and 1995 at the Rizzoli Orthopaedic Institute and 4 patients treated between 1997 and 2000 at the Division of Orthopaedics at the Maggiore Hospital are evaluated. Based on the Marotte classification, the patients are divided into 4 groups, by site of dislocation of the radial capitellum and amount of comminution of the fracture of the ulna. A clinical and radiographic evaluation was made after a mean follow-up of 5.3 years based on Anderson criteria. The results obtained were excellent in 17 patients (37.8%) satisfactory in 13 (28.9%), dissatisfactory in 12 (26.7%); 3 patients were considered to be failures (6.7%), the best results were obtained in type I anterior dislocations.

    ABSTRACT: Subtrochanteric fractures are a typical pathology in the elderly patient, they are not very common and they are difficult to treat. The general conditions of these patients, often at the limit of operability, are further compromised by surgery and time spent in bed, leading to the death of the patient in a high percentage of cases. The fracture is often spyroid, it has multiple fragments, with interruption of the medial cortical bone. The quality of the bone, because of the marked osteoporosis, does not guarantee the good hold of the means of fixation used. The use of intramedullary nailing is a safe method, that allows for stabilization of the fracture without excessive blood loss, it allows for early partial weight-bearing and it has a lower number of complications as compared to other methods. Between 1-1-97 and 31-12-00 a total of 59 persubtrochanteric fractures were treated; there were 15 males and 44 females. A Gamma Long nail was used in 46 cases, a Gamma Standard in 13. Eleven of the patients died within 6 months. A total of 27 patients aged an average of 78 years (minimum 65, maximum 87) were evaluated at a mean follow-up of 10 months (minimum 7, maximum 27). A Gamma Long nail had been used in 18 cases, and Gamma Standard in 8. Partial weight-bearing was allowed after a mean of 20 days (minimum 10, maximum 35), total weight-bearing after a mean of 60 days (minimum 40, maximum 75). Consolidation was obtained after a mean of 4 months (minimum 3, maximum 7). There were no significant complications.
