We present 3 cases of arthroscopically treated intraarticular osteoid osteoma of the ankle. Emphasis is on the high index of suspicion for this lesion, the appropriate imaging modality and the efficacy of arthroscopic excision of these tumors with superficial location in the talus and tibial plafond. 相似文献

The incidence of hip fractures in the period 1971 -1976 was calculated. the overall incidence was about 3 per thousand above the age of 50 years and about 20 per thousand above the age of 80 years. hip fractures were twice as prevalent in females as in males and the incidence was found to double for each 5-year increment in age. the percentage of femoral neck fractures decreased with age in females but was constant in males. 相似文献

The significance of endogenic factors in the localization of the fractures of the proximal femur was studied in 373 patients, with 402 fractures. A statistically significant relation was found between muscular disturbances of the affected leg and trochanteric fractures, while the incidence of femoral neck fractures was high in osteoporotic but physically active individuals. 相似文献

Sex, age and stability were recorded in 376 cases of trochanteric femoral fractures. In 168 cases the age and sex specific incidence was determined. When comparing our results with those in previous studies from the same region there was no increase that could not be related to age. This is in contrast to other reports from Scandinavia where investigators have found an increase in fracture incidence that could not be explained by the increasing number of old people. We, as others, have found a high proportion of unstable fractures. The unstable fractures did not occur more frequently in the oldest age groups. 相似文献

Over a period of 5 years, 55 re-operations with internal fixation were performed on 51 patients. The re-operations constituted 9.2 per cent of all operations employing internal fixation for subcapital fractures of the femur during that period. The indications for re-nailing were penetration of die nail through the femoral head, or slipping of the nail, with or without dislocation of the fracture.
Only 26 per cent of the re-nailed fractures healed. Seventy-three per cent showed avascular necrosis and 61 per cent non-union. 相似文献

Vitamin D Metabolism and Osteomalacia in Patients with Fractures of the Proximal Femur 总被引:1,自引:0,他引:1
Bjarne Lund Ole Helmer S rensen Birger Lund Flemming Melsen Leif Mosekilde 《Acta orthopaedica》1982,53(2):251-254
A high frequency of histological osteomalacia (25 per cent) was seen in patients with fractures of the proximal femur. No correlation was found between the levels of circulating 25-hydroxyvitamin D (25-OHD) or 1,25-dihydroxyvitamin D (1,25-(OH)2D) and the bone histomorphometric changes.
The serum 25-OHD levels were normal, which excludes a dietary vitamin D deficiency or a reduced hepatic hydroxylation of the vitamin. The mean serum 1,25-(OH)2D concentration was significantly reduced in the whole patient group, but surprisingly the levels were normal in those with histological osteomalacia, indicating that an impaired conversion of 25-OHD to 1,25-(OH)2D was not the primary cause of the bone disease. A reduced sensitivity to 1,25-(OH)2D might be a possible explanation for the osteomalacia. 相似文献

Background
The ideal management of distal femur fractures in the elderly is unclear. Acute arthroplasty has the theoretical advantage of earlier mobilization. We examined the outcomes of patients 70 years and older who underwent open reduction internal fixation (ORIF) vs distal femoral replacement (DFR) for comminuted, intra-articular distal femur fractures.Methods
A retrospective review of patients with AO/OTA classification 33C distal femur fractures treated with either ORIF or DFR was performed. Outcomes including all-cause reoperation, length of stay, fracture union, postoperative complications, use of ambulatory device and living situation at 1 year, and mortality were evaluated.Results
The study cohort included 38 patients: 10 underwent DFR and 28 ORIF. Mean patient age for both cohorts was 82 years. No difference in comorbidities or mechanism of injury was found between groups. The incidence of reoperation was 11% in the ORIF group and 10% in the DFR group. In the ORIF group, the average time to fracture union was 24 weeks, with a nonunion incidence of 18%. Twenty-three percent of ORIF group were wheelchair dependent vs none in the DFR cohort, although not statistically significant. Differences between the groups with respect to all-cause reoperation, living situation or need for ambulatory device at 1 year, and 1-year mortality did not reach statistical significance.Conclusion
Nearly 1 in 5 patients older than 70 years developed a nonunion after ORIF of an intra-articular distal femur fracture. At 1-year follow-up, all patients in DFR group were ambulatory while 1 in 4 in the ORIF group were wheelchair bound. 相似文献13.

Introduction There are various studies that reviewed the effect of cigarette smoking in fracture healing process. Nonunion, delayed union, and residual pain are the significant risk factors associated with smoking and fracture healing. Little has been known about the impact of smoking in distal radius fracture healing. We intend to explore in brief the effect of smoking in distal radius fracture healing and comparing it with nonsmokers having the same fracture fixation and analyze the outcomes with respect to fracture healing and return of function. Materials and Methods Of the total 186 patients, 92 were included in the study with ( n = male: 31, female: 61) mean age of 60.2 years. They were divided into two groups: smoking ( n = 43) and nonsmoking ( n = 49). All had surgical fixation of the distal radius with volar locking plate and started on early mobilization. The range of motion of the wrist, grip, visual analog scale, quick disabilities of the arm and shoulder and hand score, Mayo wrist score, and bone healing period were noted between these two groups and compared with statistical analysis. Results The mean follow-up period was 8.7 months. There was a significant association of young age and male patients having distal radius fractures in the smoking group ( p < 0.05). All fractures healed well in both groups without complications. There was no significant difference between these two groups in terms of range of motion, grasp, bone healing period, and functional outcomes. Conclusion Despite the well-known fact that, smoking has negative implications in the fracture healing process, we found group of patients (smoking and nonsmoking) with distal radius fractures treated by volar locking plates healed well with good radiological union and excellent functional outcome There is no significant influence of smoking in distal radius fracture fixation. 相似文献

Intraosseous Vascularity of the Distal Radius: Anatomy and Clinical Implications in Distal Radius Fractures 总被引:1,自引:0,他引:1

This study aimed to describe the intraosseous blood supply of the distal radius and its clinical implications in distal radius
fractures. Twelve adult wrists from fresh cadavers (six males, six females, 50–90 years of age, mean 68 years) were injected
through the brachial artery with latex. Dissections were performed using magnifying loupes and hands were processed using
the Spalteholz technique. The distal radius was supplied by three main vascular systems: epiphyseal, metaphyseal, and diaphyseal.
The palmar epiphyseal vessels branched from the radial artery, palmar carpal arch, and anterior branch of the anterior interosseous
artery. These vessels entered the bone through the radial styloid process at level of the Lister's tubercle but palmar and
sigmoid notch. The dorsal contribution to Lister's tubercle is to the dorsal epiphyseal vessels. The intraosseous point of
entry to the dorsal epiphyseal vessels was from the fourth and fifth extensor compartment arteries. In the metaphyseal area,
we found numerous periosteal and cortical branches originating deep in the pronator quadratus and the anterior interosseous artery. These branches provided the main supply to the distal radius. Vessels perforated the
bone and formed an anastomotic network. In the diaphyseal area, only the nutrient vessel provided intraosseous vascularity
in the distal radius. Numerous metaphyseal–epiphyseal branches arise within the pronator quadratus and the anterior interosseous artery and course towards the distal radius. These branches may be fundamental to the healing
of the distal radius fractures and make nonunion a rare complication. 相似文献
