We retrospectively reviewed 16 children younger than 13 years with 17 fractures of the shafts of the radius or ulna or both who had undergone an open reduction-internal fixation (ORIF). ORIF was performed when a closed reduction was deemed unacceptable in 14 radius fractures and for three unstable open fractures of the radius. The average age was 9.4 +/- 2.3 years (range, 5.0-12.5). Of the 14 fractures with an unacceptable closed reduction, soft-tissue interposition was encountered in seven. Fixation was secured by plates and screws, percutaneous Steinmann pins, or intramedullary Steinmann pins. There were no delayed unions or nonunions, no infections, and no neurovascular injuries. The average follow-up was 12.3 months; all 17 fractures had excellent results (forearm rotation loss of < 10 degrees). Our study indicates that excellent results can be expected with no increased risk of complications if the treating physician elects to proceed with an ORIF in a pediatric forearm fracture with proper indications. 相似文献

The clinical and functional outcomes for patients treated with open reduction and plate fixation of displaced tibial pilon fractures were determined. A retrospective search of the authors' trauma database was conducted for AO and Orthopaedic Trauma Association Code 43 injuries (pilon fractures) in adults 18 years or older who were treated between December 1988 and December 1992. The group of 64 patients who required open reduction and internal fixation to treat their fractures make up the primary cohort for this analysis. Twenty of these cases required no fibular fixation; the remainder were mostly fixed with 1/3 tubular or 3.5-mm compression plates. Tibial fixation was done using most commonly 3.5-mm cloverleaf plates, 1/3 tubular plates, or both. Of the 64 patients treated with open reduction and internal replacement, four (5%) patients had deep infection develop. Two (7%) of 14 patients had open fractures, and two (4%) of 50 patients had closed fractures. Three of these four patients smoked tobacco products; one was also an intravenous drug abuser. Staphylococcus aureus was the organism in two cases; Enterobacter, in the other two. The infection was controlled with a free flap in two cases, with antibiotics and wound debridement in one and with an arthrodesis in one. Thirty of the 64 patients completed the Short Form-36; two of these patients had bilateral fractures. The study group had significant differences in general health perceptions, physical function, physical role function, emotional role function, social and mental function, and pain and energy levels when compared with age matched population data and patients with tibial plateau fractures. The effect of other injuries on these functional status results cannot be determined specifically. 相似文献

PURPOSE: This study evaluates the long-term results of open reduction without fixation for displaced fractures of the condylar process. PATIENTS AND METHODS: Clinical and radiologic examinations were performed on 27 patients with 29 operated joints an average of 6.7 years postoperatively. The postoperative result was evaluated on the basis of occlusal and joint function, as well as radiographic assessment of condylar changes. RESULTS: Clinically, satisfactory results were achieved. Radiologically, despite correct intraoperative alignment of the fractured segments, a slight medial deviation of the condylar process was found on the posteroanterior radiograph. However, in only two cases was a 20-degree deviation observed. On final follow-up, 48% of the cases had a normal condylar configuration radiologically, and in the remaining cases, normal function was established even though there were condylar changes. Fully exposed and devascularized condylar processes generally showed more severe changes than those in which partial vascularization was maintained. CONCLUSION: The surgical management described enables a satisfactory outcome to be achieved with dislocated condylar process fractures. 相似文献

Displaced fractures of the glenoid fossa are an uncommon and anatomically diverse group of injuries. Failure to restore anatomy in these fractures results in poor outcome in most cases. The success of a treatment protocol that encompasses appropriate preoperative imaging, injury pattern assessment, prudent approach choice, and a comprehensive reduction and fixation tactic was evaluated. Twenty-seven patients were assessed clinically and radiographically at a mean followup interval of 43 months from surgery. Anatomic reconstruction was achieved in 24 (89%) patients. Three patients had residual joint incongruities measuring 2 mm or less. The only perioperative complication was a partial superficial wound dehiscence. Two additional patients had infraspinatus palsies of indeterminate origin. Functional rating revealed six (22%) excellent, 16 (60%) good, three (11%) fair, and two (7%) poor outcomes. The fair and poor outcomes largely were related to associated injuries. These findings show that anatomic surgical reconstruction with a low complication rate and good functional outcome can be obtained for most patients with glenoid fossa fractures. 相似文献

The results following internal fixation of displaced subcapital femoral fractures are poorer than for undisplaced fractures and are determined by both the quality of the initial reduction and the accuracy of implant placement. In a series of 26 consecutive displaced fractures internally fixed with Richards hip pins, satisfactory reduction was achieved in only 15 hips. Accurate reduction is a prerequisite for correct screw placement and occurred in only 4 of the 11 poorly aligned fractures, as opposed to 11 of the 15 well reduced ones. A total of 10 hips required a further surgical procedure as the result of complications. These results highlight the importance of accurate fracture reduction in facilitating implant placement as well as the importance of good surgical technique rather than reliance purely upon the implant. These already common fractures are assuming increasing socioeconomic importance as the elderly population grows, and successful management is vital for both the individual patient and future demands on the health service. 相似文献

Intra-articular calcaneal fractures are associated with significant long-term morbidity, and considerable controversy exists regarding the optimum method of treating them. The contact characteristics in the intact subtalar joint were determined at known loads and for different positions of the ankle and subtalar joint, using pressure-sensitive film (Super Low; Fuji, Itochu Canada Ltd, Montreal, Quebec). We measured the contact area to joint area ratio (pressure > 5 kg force/cm2 [kgf/cm2]) which normalizes for differences in joint size and the ratio of high pressure zone (>20 kgf/cm2) as a reflection of overall increase in joint pressure. Three simulated fracture patterns were then created and stabilized with either 1 or 2 mm of articular incongruity. Eight specimens were prepared with a primary fracture line through the posterior facet, eight with a joint depression-type fracture, and six with a central joint depression fracture. A measure of 1 to 2 mm of incongruity in the posterior facet for all three fracture patterns produced significant unloading of the depressed fragment, with a redistribution of the overall pattern of pressure distribution to parts of the facet that were previously unloaded. 相似文献

Posterior sternoclavicular joint (SCJ) dislocations are most often stable after reduction but may be associated with significant complications related to the location of the medial head of the clavicle within the mediastinum. In rare instances, a posterior SCJ dislocation is irreducible or redislocates after a closed reduction. Because of the potential hazards related to compression of vital structures within the superior mediastinum, open reduction and internal fixation is usually required. Although open reduction is widely accepted as the method of choice, the best method for achieving stable fixation remains unanswered. We present the case of an unstable SCJ stabilized, in anatomic position, with two large-bore cannulated screws in conjunction with open reduction. We believe that the risk of hardware migration reported with the use of pins and wires and its catastrophic complications are greatly minimized using our technique. 相似文献

Anatomic reduction, typically obtained by direct visualization through an arthrotomy and internal fixation (open reduction and internal fixation), is the traditional treatment method for displaced intraarticular condylar fractures of the distal femur. We present a case report describing an alternative treatment method, namely, arthroscopic reduction and internal fixation, of a displaced, malrotated intraarticular lateral femoral condyle fracture of the knee. The potential benefits of decreased blood loss, shortened operative time, excellent intraarticular visualization, decreased soft tissue dissection, and shortened postoperative recovery are outlined. 相似文献

STUDY DESIGN: An analysis of the outcome and effectiveness of instrumented arthrodesis of the lumbosacral spine in elderly patients conducted using a review of records, assessment of fusion via plain radiographs, and a two-part questionnaire. OBJECTIVE: To ascertain the outcome and efficacy of instrumented arthrodesis of the lumbosacral spine in patients 60 years of age and older. BACKGROUND DATA: From 1987 to 1991, 38 patients of at least 60 years of age underwent instrumented arthrodesis of the lumbosacral spine using the Wiltse or Selby pedicle screw fixation system (Advanced Spine Fixation Systems, Inc., Irvine, CA). Patients were considered for surgery only after attempts at conservative management, including physical therapy, medication, injection blocks, and home exercises, had proven unsuccessful. METHODS: Follow-up examinations were performed 3 months, 6 months, 1 year, and 2 years after surgery. Fusion was assessed using plain radiographs, including flexion-extension films. Inpatient and outpatient records were reviewed, and a two-part questionnaire was used to establish the effect of surgery on function and lifestyle. Thirty patients responded to the questionnaire. Follow-up observation of the patients ranged from 25 to 56 months. The mean age was 73.8 years (range, 60-90 years). RESULTS: The mean co-morbidity was 1.7. Based on the authors' method of evaluation of fusion, the fusion rate was 92%. Fifty-seven percent of the patients reported excellent or good results, 26% reported fair results, and 17% reported poor results. Functional gains of 50% or more were reported by 71% of the respondents. Female patients had significantly more complications than male patients, but reported comparable outcomes. CONCLUSION: Despite the increase in age, co-morbidity, and associated risk of perioperative complications inherent in this population, an outcome comparable with that of younger patients is reported. 相似文献

BACKGROUND: In dealing with displaced proximal humerus fractures, there is still much controversy in treatment modalities. The latest investigations emphasize the concept of minimal exposure and rigid fixation. METHODS: The technique of closed reduction and percutaneous fixation with cannulated screws and k-pins was performed on 19 patients with two- and three-part proximal humerus fractures. The outcomes were evaluated with a mean follow-up of 21 months. RESULTS: All except one case had a solid union of the fracture. Sixteen of 19 patients (84%) acquired good or excellent results according to Neer's classification. No further collapse or avascular necrosis was found. CONCLUSION: The method of closed reduction and percutaneous fixation, although technically demanding, yields satisfactory results in displaced proximal humerus fracture. Cannulated screws provided rigid fixation that was the underlying tenet for early functional retrieval. 相似文献

A retrospective case reference study examining the use of alcohol and tobacco in 303 women aged 40 or over suffering from oral or oropharyngeal cancer was conducted in the south-west Netherlands. Both alcohol and tobacco consumption are important in the development of oral and oropharyngeal cancer with increased consumption of both markedly increasing the risks of cancer, but alcohol having the greater effect. 相似文献

Ten cases of an isolated fracture of the lesser tuberosity and their long-term outcome are described. The patient ages at the time of injury ranged from 11 to 68 years, averaging 30 years. In six cases, the injury was acute; in four cases, it had occurred more than 6 months previously. Of the six acute cases: three were treated conservatively, and the result was satisfactory for all of them; surgery was carried out in the other three cases, of which, two outcomes were judged to be excellent, and one outcome was satisfactory. Regarding the four chronic cases, muscle-strengthening exercises were given in two cases, whereas an operation was performed after exercise failed in the remaining two cases. The results of all four cases were graded as excellent. The combination of open reduction and internal fixation is the method most often recommended for acute cases. In chronic cases, conservative treatment is usually the most appropriate. However, when conservative treatment proves to be ineffective, then open reduction and internal fixation should be considered. 相似文献

The aim of this paper is to review the incidence and characteristics found in traumatic spinal cord injury (SCI) occurring in patients with long-standing ankylosing spondylitis (AS). The incidence of patients with traumatic SCI admitted to our unit from January 1984 to February 1996 was 2% (15 out of 893). They were all men with a mean age of 56 years. Most frequently the etiology of the lesion was a motor vehicle accident and the injury was mainly due to a hyperextension mechanism. Acute spinal fracture occurred in 13 patients, all involving the cervical region. No fracture was observed in two patients with thoracic neurological level. Three patients presented with an interval free period of neurological symptoms in whom a spinal epidural hematoma was visualized with magnetic resonance imaging. On admission eight patients were diagnosed as having complete SCI and the other seven an incomplete SCI. In the acute phase, respiratory complications were most frequent, causing six patients to die. Treatment was conservative in 14 patients. Multidisciplinary management of these patients should be implemented in an institution equipped with both a Spinal Injury Unit and an Intensive Care Unit. 相似文献

Between August 1980 and September 1993, 35 tibiotalar arthrodeses in 34 patients with primary and secondary osteoarthritis of the ankle were performed. Two different surgical techniques were employed. Internal screw fixation according to Wagner and Pock [20] and an external fixation method according to the resection compression arthrodesis by Charnley and Muller [14]. Twenty patients with 21 fusions could be investigated retrospectively. For evaluation we used self-assessment, clinical examination and radiographic analysis in combination with the score described by McGuire et al. [12]. In 80% the results were good and satisfactory with a median improvement of 23 score points on a scale of 100% 95 points, respectively. The most important advantages were pain relief and increase of walking distance. The fusion rate was 95%. We found osteoarthritis in the neighbouring joints did not have any influence on the surgical result. With respect to the two surgical techniques, the internal screw fixation method achieved fusion earlier with fewer complications and better improvement according to the McGuire score. Tibiotalar fusion is a safe therapy with reproducible good results involving pain relief, full weight-bearing and increase of walking distance. 相似文献

OBJECTIVES: Prostate cancer (PCa) has a familial predisposition imparting an increased risk of developing the disease in those with a family history. The pathologic characteristics are similar to sporadic cases; however, the disease-free survival rates of hereditary PCa have recently been disputed, with one major study suggesting that familial cases have higher recurrence rates. Our study seeks to support or refute this association and to evaluate the genetic biomarkers p53, bcl-2, Ki-67, and neovascularity between familial and sporadic disease. METHODS: We retrospectively reviewed data of 573 patients who underwent radical prostatectomy over an 11-year period. Of these, 474 patients had known family history data. Univariable statistical analysis using the Pearson chi-square test and Kaplan-Meier disease-free survival analysis was performed to identify any correlation between the tested variables and family history. Smaller subsets of this cohort that had available archival material for immunohistochemical staining and family history data were analyzed in a similar manner. RESULTS: The preoperative variables (prostate-specific antigen, prostatic acid phosphatase, clinical stage, highest biopsy Gleason sum, and glandular differentiation) and postoperative variables (stage, highest Gleason sum, and glandular differentiation) did not correlate with family history. Kaplan-Meier disease-free survival analysis revealed no differences between sporadic and familial cases. The analysis of p53, bcl-2, Ki-67, and angiogenesis revealed that only increasing p53 expression and positive family history of PCa approached significance (P = 0.057). CONCLUSIONS: Prognostic variables routinely used in PCa and selected genetic biomarker immunostaining abnormalities are not significantly different in men with and without a family history of PCa. Disease-free survival after radical prostatectomy is also unaffected by family history. 相似文献

OBJECTIVE: To modify the technique of multifetal pregnancy reduction and to study the outcome of reduced twins in comparison with nonreduced twins and high-order multiple gestations. DESIGN: Prospective controlled study. SETTING: The Egyptian IVF-ET Center, Cairo. PATIENT(S): Seventy-five patients with high-order multiple pregnancies resulting from assisted reproduction. Controls were 40 nonreduced twin pregnancies and 22 high-order multiple gestations. INTERVENTION(S): Transvaginal ultrasonically guided multifetal pregnancy reduction was performed. The first 30 cases were done using KCl as a cardiotoxic agent. The modified technique was used for the last 45 cases at an earlier gestational age (approximately 7 weeks) by eliminating the use of KCI and by aspirating the embryonic parts. MAIN OUTCOME MEASURE(S): Miscarriage rate, gestational age at delivery, birth weight, and pregnancy complications. RESULT(S): Using the modified technique, the miscarriage rate was 8.8% and 41 patients delivered between 32 and 39 weeks of gestation (mean+/-SD, 36.9+/-2.45 weeks). The mean (+/-SD) birth weight was 2,450.51+/-235.44 g. The miscarriage rate, fetal wastage rate, mean gestational age, and mean birth weight were similar in reduced and nonreduced twins and were significantly better than in nonreduced triplets and quadruplets. CONCLUSION(S): The modified technique of multifetal pregnancy reduction significantly improved outcomes, which were similar to those of nonreduced twins resulting from assisted reproduction and significantly better than those of nonreduced triplets and quadruplets. 相似文献
