1/90. Myofasciocutaneous expansion in the tegumentary rehabilitation of the amputation stump.In post-traumatic amputations, in particular in leg amputations, the presence of an unstable scar or of ulcerous areas that are difficult to heal in the site of the amputation stump constitutes a repair problem that is not easily solved. In this specific field of reconstruction skin expansion has earned significant agreement, and is even considered to be a safe and reliable method for the surgical rehabilitation of the amputation stump, allowing us to obtain high-quality tegumentary covering, with no excessive thickness, that adapts well to the prosthesis and to the underlying skeleton, and that is characterized by good sensitivity of protection. Tegumentary amplification may, in some cases, also become myocutaneous, allowing us to obtain more tissue thickness for protection in patients submitted to chronic loading that lasts longer and in those with thin teguments, in which traditional expansion could determine excessive narrowing of the tegumentary covering, following atrophy caused by compression of the subcutaneous adipose tissue.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
2/90. Post-traumatic distal nerve entrapment syndrome.Eleven patients with paralysis of muscle groups in the upper or lower extremity were clinically diagnosed after previous proximal direct trauma to the corresponding peripheral nerves, without complete nerve disruption. patients were seen within an average of 8 months after trauma (minimum 3 months and maximum 2 years after). Nerve lesions were caused either by gunshot, motor-vehicle accident, and other direct trauma or, in one case, after tumor excision. All patients presented with complete sensory and motor loss distal to the trauma site, but demonstrated a positive Tinel sign and pain on testing over the "classic" (distal) anatomic nerve entrapment sites only. After surgical release through decompression of the nerve compression site distal to the trauma, a recovery of sensory function was achieved after surgery in all cases. Good-to-excellent restoration of motor function (M4/M5) was achieved in 63 percent of all cases. Twenty-five percent had no or only poor improvement in motor function, despite a good sensory recovery. Those patients in whom nerve compression sites were surgically released before 6 months after trauma had an improvement in almost all neural functions, compared to those patients who underwent surgery later than 9 months post trauma. A possible explanation of traumatically caused neurogenic paralysis with subsequent distal nerve compressions is provided, using the "double crush syndrome" hypothesis.- - - - - - - - - - ranking = 4keywords = compression (Clic here for more details about this article) |
3/90. 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 = 689.61408092649keywords = fracture (Clic here for more details about this article) |
4/90. Field hospital treatment of blast wounds of the musculoskeletal system during the Yugoslav civil war.The spectrum of wounding and treatment of forty-one patients with musculoskeletal blast injuries at a U.S. military field hospital in the former yugoslavia was reviewed. patients underwent wound exploration, irrigation, debridement, broad-spectrum antibiotic therapy, early fracture stabilization, and appropriate reconstructive surgery. Four patients developed wound infections. Two patients died as a result of their injuries (overall mortality 5 percent). There were three below-knee amputations and five other amputations (above-knee, ankle, midtarsal, partial forefoot, and finger). Three patients sustained lumbar burst fractures from mines that exploded under their vehicles, resulting in paraplegia in one case. Our patients underwent 112 surgical procedures, an average of 2.1 per patient. Twenty-two patients (54 percent) had other injuries or conditions in addition to their orthopaedic wounds. There were wide variations in the bone and soft tissue injuries caused by detonating ordnance, and the tissue damage was qualitatively different from that caused by gunshot wounds. Early debridement, leaving wounds open, and treatment with broad-spectrum antibiotics were important factors in wound healing to allow subsequent successful reconstructive surgery in an austere field setting.- - - - - - - - - - ranking = 344.80704046324keywords = fracture (Clic here for more details about this article) |
5/90. 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 = 1379.228161853keywords = fracture (Clic here for more details about this article) |
6/90. Necrotizing fasciitis.A 31-year-old Pakistani man was admitted to hospital after sustaining a Grade I compound fracture of the mid-shaft of the left tibia and fibula following a motor vehicle accident. He developed septicaemic shock, acute renal failure and Group A streptococcal necrotizing fasciitis of the left leg. The patient underwent an above knee amputation followed by disarticulation of the left hip with extensive debridement. He was treated with benzylpenicillin, vancomycin, inotropes and continuous haemodialysis and survived without further sequelae. Subsequently, skin grafting was done over the wound site. This case highlights the role of Group A streptococcus as a cause of this rare and life-threatening infection.- - - - - - - - - - ranking = 172.40352023162keywords = fracture (Clic here for more details about this article) |
7/90. Flap transfers for the treatment of perichondrial ring injuries with soft tissue defects.Seven cases (six fresh) of perichondrial ring injury with skin defects were treated using flap transfers. The study included four boys and three girls ranging in age from 2 to 9 years (average 6). They were followed up for an average of 8 years and 10 months. The period from injury to flap coverage was 8-12 days, with an average of 10 days in the fresh cases. Fracture was noted in four cases, with one an epiphyseal fracture. Peroneal flaps were transferred in four cases, latissimus dorsi myocutaneous flaps in two, and gastrocnemius muscle flap in one. Six flaps survived perfectly, and one failed due to venous thrombosis. This latter case was treated with a cross leg flap. Postoperative radiographic assessments confirmed partial growth plate arrest in the chronic case, but all the fresh cases had no postoperative growth disturbance. Flap coverage, for perichondrial ring injuries with wide skin defects, is a useful method not only for skin coverage, but for the prevention of growth disturbances as well.- - - - - - - - - - ranking = 172.40352023162keywords = fracture (Clic here for more details about this article) |
8/90. Management of lawnmower injuries to the lower extremity in children and adolescents.Lawnmower-associated trauma remains a substantial source of extremity injury in the pediatric and adolescent patient populations, producing complex wounds that require a combined orthopedic and plastic surgical approach. The authors review their experience with 16 patients, 2 to 17 years of age (mean age, 6.2 years), who were admitted to Duke University Medical Center for lower extremity lawnmower trauma between January 1988 and December 1999. The average hospitalization time was 13.5 days, and an average of 2.9 surgical procedures per patient were performed. Early debridement and bony fixation were carried out in all patients; 8 patients sustained traumatic amputations. Fifteen of 20 nonamputation fractures involved the foot and were managed with either closed reduction or K-wire fixation. Three of five long-bone fractures underwent external fixation. Wound closure was achieved with direct closure or skin grafting in the majority of patients. However, five microsurgical free flap transfers were required for extensive defect reconstruction of the foot (N = 4) and knee (N = 1). Adequate immediate debridement, fracture reduction, and early primary or if necessary secondary wound coverage including microsurgical free tissue transfer to prevent further damage and long-term disability in these type of devastating injuries is recommended.- - - - - - - - - - ranking = 517.21056069487keywords = fracture (Clic here for more details about this article) |
9/90. limb salvage of lower-extremity wounds using free gracilis muscle reconstruction.An extensive series reviewing the benefits and drawbacks of use of the gracilis muscle in lower-extremity trauma has not previously been collected. In this series of 50 patients, the use of microvascular free transfer of the gracilis muscle for lower-extremity salvage in acute traumatic wounds and posttraumatic chronic wounds is reviewed. In addition, the wound size, injury patterns, problems, and results unique to the use of the gracilis as a donor muscle for lower-extremity reconstruction are identified. In a 7-year period from 1991 to 1998, 50 patients underwent lower-extremity reconstruction using microvascular free gracilis transfer at the University of maryland shock Trauma Center, Johns Hopkins Hospital, and Johns Hopkins Bayview Medical Center. There were 22 patients who underwent reconstruction for coverage of acute lower-extremity traumatic soft-tissue defects associated with open fractures. The majority of patients were victims of high-energy injuries with 91 percent involving motor vehicle or motorcycle accidents, gunshot wounds, or pedestrians struck by vehicles. Ninety-one percent of the injuries were Gustilo type IIIb tibial fractures and 9 percent were Gustilo type IIIc. The mean soft-tissue defect size was 92.2 cm2. Successful limb salvage was achieved in 95 percent of patients. Twenty-eight patients with previous Gustilo type IIIb tibia-fibula fractures presented with posttraumatic chronic wounds characterized by osteomyelitis or deep soft-tissue infection. Successful free-tissue transfer was accomplished in 26 of 28 patients (93 percent). All but one of the patients in this group who underwent successful limb salvage (26 of 27, or 96 percent) are now free of infection. Use of the gracilis muscle as a free-tissue transfer has been shown to be a reliable and predictable tool in lower-extremity reconstruction, with a flap success and limb salvage rate comparable to those in other large studies.- - - - - - - - - - ranking = 517.21056069487keywords = fracture (Clic here for more details about this article) |
10/90. Traumatic hemipelvectomy: case report and literature review.A case of traumatic hemipelvectomy with survival is presented, apparently the sixth reported case in the literature. Following complete left hemipelvectomy and fracture of the right acetabulum, the patient recovered, demonstrated voluntary bowel and urinary control, was full weight bearing on crutches (against advice), and refused a bucket seat or prosthesis, as well as neurosurgical consultation. The patient was then unfortunately lost to followup.- - - - - - - - - - ranking = 172.40352023162keywords = fracture (Clic here for more details about this article) |
