Background:
Management of periprosthetic supracondylar femoral fractures is difficult. Osteoporosis, comminution and bone loss, compromise stability with delayed mobility and poor functional outcomes. Open reduction and internal fixation (ORIF) with anatomic distal femoral (DF) locking plate permits early mobilization. However, this usually necessitates bone grafting (BG). Biological fixation using minimally invasive techniques minimizes periosteal stripping and morbidity.Materials and Methods:
31 patients with comminuted periprosthetic DF fractures were reviewed retrospectively from October 2006 to September 2012. All patients underwent fixation using a DF locking compression plate (Synthes). 17 patients underwent ORIF with primary BG, whereas 14 were treated by closed reduction (CR) and internal fixation using biological minimally invasive techniques. Clinical and radiological followup were recorded for an average 36 months.Results:
Mean time to union for the entire group was 5.6 months (range 3-9 months). Patients of ORIF group took longer (Mean 6.4 months, range 4.5-9 months) than the CR group (mean 4.6 months, range 3-7 months). Three patients of ORIF and one in CR group had poor results. Mean knee society scores were higher for CR group at 6 months, but nearly identical at 12 months, with similar eventual range of motion.Discussion:
Locked plating of comminuted periprosthetic DF fractures permits stable rigid fixation and early mobilization. Fixation using minimally invasive biological techniques minimizes morbidity and may obviate the need for primary BG. 相似文献2.

INTRODUCTION
Rupture of extensor pollicis longus (EPL) tendon is a recognised complication following volar plate fixation of distal radius fractures, usually from attrition caused by prominent screws. We sought to identify the screw holes in some of the most commonly used plates which may precipitate tendon injury.SUBJECTS AND METHODS
Three fixed-angle volar locking plates were sequentially positioned into 18 cadaveric arms. A wire was passed through each of the holes in the plates using a locking guide and the dorsal relationships noted.RESULTS
Each plate had specific ‘high-risk’ holes which directed the wire towards the EPL groove. The central screw holes appeared mostly implicated in EPL injury.CONCLUSIONS
Awareness of ‘high-risk’ holes and appropriate minor alterations in surgical technique may consequently decrease the incidence of EPL irritation and rupture. 相似文献3.
Results of titanium locking plate and stainless steel cerclage wire combination in femoral fractures
Bilal Farouk El-Zayat Steffen Ruchholtz Turgay Efe Jürgen Paletta Dimitri Kreslo Ralph Zettl 《Indian Journal of Orthopaedics》2013,47(5):454-458
Background:
Some in vitro studies warn combining different metals in orthopedic surgery. The aim of this study is to determine the impact of combining titanium and stainless steel on bone healing and the clinical course of patients undergoing internal fixation of femoral fractures.Materials and Methods:
69 patients with femoral fractures had polyaxial locking plate osteosynthesis. The locking plate was made of a titanium alloy. Two different cohorts were defined: (a) sole plating and (b) additional stainless steel cerclage wiring. Postoperative radiographs and clinical followup were performed at 6 weeks, 3 months and 12 months.Results:
Cohorts A and B had 36 and 33 patients, respectively. Patient demographics and comorbidities were similar in both groups. In two cases in cohort A, surgical revision was necessary. No complication could be attributed to the combination of titanium and stainless steel.Conclusion:
The combination of stainless steel cerclage wires and titanium plates does not compromise fracture healing or the postoperative clinical course. 相似文献4.

Background:
Neglected femoral neck fracture in adults still poses a formidable challenge. Existing treatment options varies from osteotomy (with or without graft) to osteosynthesis using various implants and grafting techniques (muscle pedicle, vascularized, and nonvascularized fibula). The aim of this study was to assess outcome of nonvascularized fibular strut graft and cancellous screw fixation in neglected femoral neck fractures in the younger age group.Materials and Methods:
Medical records of 32 patients of neglected femoral neck fracture, in the age group of 22-45 years (mean 37.8 years), operated between May 1994 to December 2001, were retrospectively reviewed. After the application of inclusion and exclusion criteria, 28 patients having three years minimum follow-up (mean 4.6 years) were included. Delay between injury and operation varied from four weeks to 42 weeks (mean 16.4 weeks). Closed reduction was achieved in 17 patients; open reduction through Watson-Jones anterolateral approach was performed in the remaining 15 patients in whom closed reduction failed. The fracture was transfixed with three parallel guide wires. Appropriate sized cannulated lag screw (7 mm) was then inserted in two of the wires. Selection of the third guide wire for fibula depended on the space available in both anteroposterior and lateral view.Results:
Satisfactory bony union was obtained in 25 patients, of whom in four cases, the union occurred in 10-20° (mean 15°) of varus. Nonunion occurred in three patients (9.37%), and aseptic necrosis occurred in another six patients (18.75%). Of the 25 patients where union was achieved, five patients showed excellent results; 14 good and six had poor functional result, as evaluated using modified Anglen criteria.Conclusion:
Nonvascularized fibular strut graft along with cancellous screws provides a dependable and technically less-demanding alternative procedure for neglected femoral neck fractures in young adults. Fibula being cortical provides mechanical strength besides stimulating the union and getting incorporated as biological graft. 相似文献5.
A retrospective analysis of medial opening wedge high tibial osteotomy for varus osteoarthritic knee
Chaturong Pornrattanamaneewong Surin Numkanisorn Keerati Chareancholvanich Thossart Harnroongroj 《Indian Journal of Orthopaedics》2012,46(4):455-461
Background:
Medial opening wedge high tibial osteotomy (MOWHTO) has proven to be an effective treatment for varus osteoarthritic knees. Various methods of fixation with different implant types and using either bone grafts or bone substitutes have been reported. We performed non-locking T-buttress plate fixation with autologous iliac bone graft augmentation, which is defined here as the traditional method, and locking compression plate fixation without any bone graft or bone substitute. We aimed to compare bone union and complications of these two MOWHTO techniques.Materials and Methods:
Between June 2005 and December 2007, 50 patients who underwent MOWHTO (a total of 60 knees) were retrospectively reviewed and classified into two groups: group A, which consisted of 26 patients (30 knees) was treated using T-buttress plate fixation with autologous iliac bone graft augmentation and group B, which consisted of 24 patients (30 knees) was operated upon using a medial high tibial locking compression plate without any augmentation. Demographic characteristics and radiographic outcomes, including union rate, time to union, medial osteotomy defects, and complications, were collected and compared between the two groups. The progress of all patients was followed for at least 2 years.Results:
All osteotomies united within 12 weeks after surgery. Group B had slightly longer time to union than group A (10.3 weeks and 9.5 weeks, respectively; P = 0.125). A significantly higher incidence of medial defects after osteotomy was reported in the locking compression plate group (P = 0.001). A total of 5 (8.3%) knees had complications. In group A, one knee had a superficial wound infection and another knee had a lateral tibial plateau fracture without significant loss of correction. In group B, one knee had screw penetration into the knee joint and two knees had local irritation that required the removal of the hardware.Conclusion:
Locking compression plate fixation without the use of bone grafts or bone substitutes provides a satisfactory union rate and an acceptable complication rate when compared to the traditional MOWHTO technique. Thus, we recommend using this technique for treating unicompartmental medial knee osteoarthritis. 相似文献6.

Background
We conducted this radiographic study in the elderly population with proximal humeral fracture aiming to evaluate 1) the serial changes of neck-shaft angle after locking plate fixation and 2) find relationship between change in neck shaft angle and various factors such as age, fracture pattern, severity of osteoporosis, medial support and initial reduction angle.Methods
Twenty-five patients who underwent surgical treatment for proximal humeral fracture with locking plate between September 2008 and August 2010 are included. True anteroposterior and axillary lateral radiographs were made postoperatively and at each follow-up visit. Measurement of neck shaft angle was done at immediate postoperative, 3 months postoperative and a final follow-up (average, 11 months; range, 8 to 17 months). Severity of osteoporosis was assessed using cortical thickness suggested by Tingart et al.Results
The mean neck shaft angles were 133.6° (range, 100° to 116°) at immediate postoperative, 129.8° (range, 99° to 150°) at 3 months postoperative and 128.4° (range, 97° to 145°) at final follow-up. The mean loss in the neck-shaft angle in the first 3 months was 3.8° as compared to 1.3° in the period between 3 months and final follow-up. This was statistically significant (p = 0.002), indicating that most of the fall in neck shaft angle occurs in the first three months after surgery. Relationship between neck shaft angle change and age (p = 0.29), fracture pattern (p = 0.41), cortical thickness (p = 0.21), medial support (p = 0.63) and initial reduction accuracy (p = 0.65) are not statistically significant.Conclusions
The proximal humerus locking plate maintains reliable radiographic results even in the elderly population with proximal humerus fracture. 相似文献7.
Purpose:
The aim of this study is to evaluate whether two 3.0 mm Schanz screws in two-part proximal humeral fractures (plus one additional Schanz screw or K wire in three-part fractures) can provide enough stability to allow early mobilization until healing occurs in elderly patients.Settings and Design:
This prospective study was performed in the Orthopaedic Department of our University Hospital.Patients and Methods:
We performed closed reduction and percutaneous pinning for thirty-three patients with proximal humerus fractures. Twenty-seven patients were available for the final follow-up. Of those 27 patients, 17 had two-part surgical neck fractures; while 10 had three-part fractures. For fixation, we used two 3.0 mm Schanz screws in patients with two-part fractures plus one additional Schanz screw or K wire in the 10 patients with three-part fractures.Results:
The mean Constant score modified according to the age and sex was 89.8% (range: 77.3-97.2%). Fifteen patients had excellent results, 11 patients had good results, and one patient had a fair result.Conclusion:
Closed reduction and percutaneous pinning with two Schanz screws for two-part surgical neck humeral fractures, plus an additional Schanz screw or K wire for three-part proximal humeral fractures is a useful and effective technique that provides enough stability to allow an early rehabilitation program till union occurs in elderly patients.Level of Evidence:

Objectives
Aim of our study was to assess the role of addition of fibular strut graft to multiple cancellous screws in functional outcome, union and complications associated with those managed by only multiple cancellous screws in fresh femoral neck fractures.Methods
A randomized control trial study was conducted on the patients of femoral neck fractures managed with multiple cancellous screws (group A) and multiple cancellous screws with fibular graft (group B). Patients aged between 20 and 50 years, having Gardens type III or IV fracture with duration of injury less than two weeks were included in the study.Results
Eighty seven cases were analysed n = 45 were in group A and n = 42 in group B. Functional outcome (Harris hip score) was excellent in 30 patients in group A as compared to 12 in Group B which was statistically significant favouring group A. The time of full weight bearing, union and non union rates showed no statistical significance (p > 0.05). On statistical grounds none of the procedures proved to be better than other.Conclusions
Fresh femoral neck fracture in young adults managed with multiple cancellous screws fixation with fibular graft has no added advantage over multiple cancellous screws fixation alone. 相似文献9.
Background:
Nonunion in diaphyseal fractures of the humerus can be treated by various modalities like plating and bone grafting, exchange nailing, fibular strut grafting and Ilizarov’s method of ring fixation. To achieve union in infected nonunion in which multiple surgeries have already been done is further challenging. We conducted a prospective study wherein the outcome of the treatment of nonunion of diaphyseal fractures of the humerus by Ilizarov’s method was analyzed.Materials and Methods:
Nineteen patients with diaphyseal nonunion of the humerus were treated by Ilizarov’s external fixator. These included nonunion after plating (n=11), intramedullary nailing (n=1) or conservative methods (n=7). In post-surgical infected nonunion (n=6), the implants were removed, debridement done, bone fragments were docked followed by application of ring fixator and compression. In aseptic nonunion (n=13), distraction for three weeks followed by compression was the protocol. Early shoulder and elbow physiotherapy was instituted. The apparatus was removed after clinical and radiological union and the results were assessed for bone healing and functional status.Results:
Fracture union was achieved in all the 19 cases. Pin site infection was seen in 2 cases (10.52%). The bone healing results were excellent in eighteen cases (94.73%) and good in one case (5.26%).The functional results were found to be excellent in fourteen cases (73.68%), good in four (21.05%) and fair in one case (5.26%).Conclusion:
Ilizarov’s method is an excellent option for treatment of septic and aseptic non union of diaphyseal fractures of the humerus as it addresses all the problems associated with non union of the humerus like infection, deformity and joint stiffness. 相似文献10.
Introduction:
Non-union following fracture of the proximal humerus is not uncommon, particularly in the elderly. This can be associated with significant morbidity due to pain, instability and functional impairment. The Polarus device (Acumed) is a locked, antegrade intramedullary nail designed to stabilize displaced 2-, 3- and 4-part fractures of the proximal humerus. We report our experience with the Polarus nail for the treatment of established non-union of the proximal humerus.Materials and Methods:
A total of 7 Polarus nails were inserted for the treatment of non-union of the proximal humerus between June 2000 and July 2007. Each fracture site was opened, debrided, stabilized with a Polarus nail and then grafted with autologous cancellous iliac crest bone. The time between injury and surgery ranged from 6 to 102 months. One patient had undergone previous fixation of her fracture using Rush intramedullary rods. All patients were females, and mean age at surgery was 63.6 years (range, 49-78 years). A retrospective review of notes and radiographs was carried out. Patients were reviewed at varying intervals postoperatively (range, 13-68 months) and assessed using the Constant shoulder-scoring system.Results:
All un-united fractures progressed to union. There were no wound complications and no postoperative nerve palsies. Functional outcome was good, even in those cases with a long interval between injury and surgery. The mean Constant score was 63 (range, 54-81). Migration of a single proximal locking screw was seen in 2 patients, and these screws required removal at 5 and 12 months, respectively, postoperatively.Conclusion:
In our experience, a locked proximal humeral nail used in conjunction with autologous bone grafting is an excellent device for the treatment of proximal humerus non-unions. 相似文献11.

Purpose
Distal radius fractures represent the most common fractures in adults. Volar locking plating to correct unstable fractures has become increasingly popular. Although reasonable primary reduction is possible in most cases, maintenance of reduction until the fracture is healed is often problematic in osteoporotic bone. To our knowledge, no biomechanical studies have compared the effect of enhancement with biomaterial on two different volar fixed-angle plates.Methods
Human fresh-frozen cadaver pairs of radii were used to simulate an AO/OTA 23-A3 fracture. In a total of four groups (n = 7 for each group), two volar fixed-angle plates (Aptus 2.5 mm locking fracture plate, Medartis, Switzerland and VA-LCP two-column distal radius plate 2.4, volar, Synthes, Switzerland) with or without an additional injection of a biomaterial (Hydroset Injectable HA Bone Substitute, Stryker, Switzerland) into the dorsal comminution zone were used to fix the distal metaphyseal fragment. Each specimen was tested load-controlled under cyclic loading with a servo-hydraulic material testing machine. Displacement, stiffness, dissipated work and failure mode were recorded.Results
Improved mechanical properties (decreased displacement, increased stiffness, decreased dissipated work) were found in both plates if the biomaterial was additionally injected. Improvement of mechanical parameters after biomaterial injection was more evident in the Synthes plate compared to the Aptus plate. Pushing out of the screws was noticed as a failure mode only in samples lacking supplementary biomaterial.Conclusions
Injection of a biomaterial into the dorsal comminution zone increases stability after volar locking plating of distal radius fractures in vitro. 相似文献12.

Background:
Minimally invasive plate osteosynthesis (MIPO) technique is reported as a satisfactory procedure for the treatment of humeral shaft fractures by the anterior approach by several authors. However, none of the published reports had a significant follow-up nor have they reported patient outcomes. We evaluated the clinical, radiographic, and functional outcome over a minimum follow-up of 2 years using the same MIPO technique to humeral shaft fracture.Materials and Methods:
32 adult patients with diaphyseal fractures of the humerus treated with MIPO between June 2007 and October 2008 were included in the study. Patients with metabolic bone disease, polytrauma, and Gustilo and Anderson type 3 open fractures with injury severity score >16 were excluded from the study. All cases were treated with closed indirect reduction and locking plate fixation using the MIPO technique. The surgery time, radiation exposure, and time for union was noted. The shoulder and elbow function was assessed using the UCLA shoulder and Mayo elbow performance scores, respectively.Results:
Of the 32 patients in the study, 19 were males and 13 were females. The mean age was 39 years (range: 22–70 years). Twenty-seven of the thirty-two patients (84.3%) had the dominant side fractured. We had eight cases of C2 type; five cases of C1 and A2 type; four cases of B2 type; three cases each of B3, B1, and A1 type; and one case of A3 type of fracture. The mean surgical time was 91.5 minutes (range: 70–120 minutes) and mean radiation exposure was 160.3 seconds (range: 100–220 seconds). The mean radiological fracture union time was 12.9 weeks (range: 10–20 weeks). Shoulder function was excellent in 27 cases (84.3%) and good in remaining 5 cases (15.6%) on the UCLA score. Elbow function was excellent in 26 cases (81.2%), good in 5 cases (15.6%), and fair in 1 case (3.1%) who had an associated olecranon fracture that was fixed by tension band wire in the same sitting.Conclusion:
MIPO of the humerus gives good functional and cosmetic results and should be considered one of the management options in the treatment of humeral diaphyseal fractures. 相似文献13.

Aims:
One of the reason for Latarjet procedure failure may be coracoid graft osteolysis. In this study, we aimed to understand if a better compression between the coracoid process and the glenoid, using a mini-plate fixation during the Latarjet procedure, could reduce the amount of coracoid graft osteolysis.Materials and Methods:
A computed tomography scan analysis of 26 prospectively followed-up patients was conducted after modified Latarjet procedure using mini-plate fixation technique to determine both the location and the amount of coracoid graft osteolysis in them. We then compared our current results with results from that of our previous study without using mini-plate fixation to determine if there is any statistical significant difference in terms of corcacoid bone graft osteolysis between the two surgical techniques.Results:
The most relevant osteolysis was represented by the superficial part of the proximal coracoid, whereas the deep part of the proximal coracoid graft is least involved in osteolysis and has best bone healing. The current study showed a significant difference only for the deep part of the distal coracoid with our previous study (P < 0.01).Discussion:
To our knowledge, there are no studies in literature that show the causes of coracoid bone graft osteolysis after Latarjet procedure.Conclusion:
Our study suggests that there is a significant difference only for the deep part of the distal coracoid in terms of osteolysis. At clinical examination, this difference did not correspond with any clinical findings.Level of Evidence:

Background:
The sliding screw-plate devices and cephalo-medullary nail devices have performed well in stable inter-trochanteric fractures in patients with reasonably good quality of bone. However, their suboptimal performance in comminuted fractures in the presence of osteoporotic bone has prompted many surgeons to consider bipolar hemiarthroplasty as the primary modality of management of comminuted inter-trochanteric fractures in elderly patients. However, long term stability of the hemiarthroplasty implant also may be compromised due to the presence of postero-medial bone loss at the area of the calcar.Materials and Methods:
We have presented a simple and effective technique of calcar grafting by harvesting cortical bone strut from the neck of the fractured femur. A total of 34 patients with inter-trochanteric fractures of the femur were treated with calcar grafting. The mean age was 79.2 years. The graft was harvested from the calcar region of the head and neck fragment of the femur and wedged between the medial femoral cortex and medial edge of the prosthesis. The mean followup period was 54.5 months.Results:
In 32 of 34 (94%) patients in our series, the calcar graft healed well without dislodgement. There was graft resorption in two patients associated with subsidence of the implant and loosening.Conclusion:
Calcar grafting using this technique provides stability to the implant in the presence of comminution and incorporates well in the majority of patients. Donor site morbidity of graft harvesting is also avoided. 相似文献15.

Background:
Nonunion and avascular necrosis (AVN) of the femoral head remains one of the major complications following femoral neck fractures. Despite various surgical techniques and internal fixation devices, the incidence of nonunion and AVN has remained unsolved. Neglected nonunion of femoral neck fracture is common in the developing world. Treatment options include rigid internal fixation with or without bone grafting, muscle pedicle bone graft, valgus osteotomy of the proximal femur with or without bone graft, valgus osteotomy or hip arthroplasty. We conducted a retrospective analysis of cases of nonunion of femoral neck fracture treated by transfracture abduction osteotomy (TFAO).Materials and Methods:
Over a period of 35 years (1974-2008), 30 patients with nonunion of femoral neck fractures were treated with TFAO over a period of 35 years (1974-2008), All patients were less than 50 years of age. Absence of clinical and radiological signs of union after four months was considered as nonunion. Patients more than 50 years of age were excluded from the study. Union was assessed at 6 months radiologically. Limb length was measured at six months. The mean duration of femoral neck fracture was 19 months (range 4 months 10 years). Results were analyzed in terms of radiological union at six months. Average followup was five years and six months.Results:
Consistent union was noted at the followup after six months in 29 cases. One case was lost to followup after five and one-half months postoperatively. However, the fracture had united in this case at the last followup. Average shortening of the limb at six months was 1.9 cm. Average neck shaft angle was 127° (range 120-145°). Five cases went into AVN but were asymptomatic. Two cases required reoperation due to back out of Moore''s pins. These were reopened and cancellous screws were inserted in the same tracks.Conclusions:
Consistent union of nonunion femoral neck fracture was noted at the followup after six months in 29 cases. The major drawback of the procedure is immobilization of the patient in the hip spica for eight weeks. 相似文献16.

Background
Two-part proximal humerus fractures are common orthopedic injuries for which surgical intervention is often indicated. Choosing a fixation device remains a topic of debate.Purpose
The purpose of this study is to compare two methods of fixation for two-part proximal humerus fractures, locking plate (LP) with screws versus intramedullary nailing (IMN), with respect to alignment, healing, patient outcomes, and complications. To our knowledge, a direct comparison of these two devices in treating two-part proximal humerus fractures has never before been studied. We hope that our results will help surgeons assess the utility of LP versus IMN.Methods
A retrospective chart review was performed on 24 cases of displaced two-part surgical neck fractures of the humerus. Twelve shoulders were treated using IMN fixation and 12 others were fixated with LP. Data collected included sociodemographic, operative details, and postoperative care and function.Results
Radiographic comparison of fixation demonstrated an average neck-shaft angle of 124° and 120° in the IMN group and LP group, respectively. Adjusted postoperative 6-month follow-up range of motion was 134° of forward elevation in the IMN group and 141 in the LP group. The differences in range of motion and in complication rates were not found to be significant.Conclusions
Our results suggest that either LP fixation or IMN fixation for a two-part proximal humerus fracture provides acceptable fixation and results in a similar range of shoulder motion. Although complication rates were low and insignificant between the two groups, a trend toward increased complications in the IMN group is noted. 相似文献17.

Purpose:
This study was undertaken to evaluate the efficacy of a proximal humeral locking plate, and to specifically study the effect of patient age and fracture type on the outcome.Materials and Methods:
Thirty-one cases of proximal humeral fractures fixed by using the proximal humeral interlocking (PHILOS) plate were reviewed.Results:
Average functional scores (minimum 18 months post operation) per AO / ASIF fracture type were 25.3 for type A, 21.4 for type B, and 22.7 for type C. There was no statistically significant difference between the groups. The functional scores for patients over 65 years of age were significantly inferior (P = 0.03). At a final radiological review (mean 12 months post operation), 30 (96%) of the patients demonstrated fracture union. Seven patients (22.5%) required a second surgical procedure.Conclusion:
We obtained both good functional results and bone healing with the PHILOS plate, irrespective of fracture type; the older patients had a poorer outcome. We caution the surgeons on the high potential for reoperations with its use. 相似文献18.
Background:
The surgical approach, type of olecranon osteotomy, method of stabilization of osteotomy, type of fracture stabilization, orthogonal vs parallel plate fixation, need for transposition of ulnar nerve, place for primary total elbow replacement, and type of rehabilitation schedule after surgical fracture treatment are the controversial issues in the treatment of complex intra-articular distal humerus fractures (C2 and C3) in adults. Severe comminution, bone loss, and osteoporosis at the site of distal articular fractures of humerus often lead to unsatisfactory results due to inadequate fixation. We hereby report the outcome of a series of intracondylar fractures of the humerus treated by open reduction and internal fixation and discuss the controversies in light of published literature.Materials and Methods:
One hundred and eighty-four patients of intra-articular fractures of distal humerus (C2 and C3) were operated by posterior transolecranon approach between January 1980 and December 2008. Initially, in the first part Chevron intra-articular osteotomy (n=108) was performed out of which 94 have been published in another publication. In later second part (1993 onward), extra-articular olecranon osteotomy (n=76) was routinely performed. Both columns were stably fixed by orthogonal methods; (n=174) however, during the last 2 years, in 10 patients with severe comminution with bone loss, stabilization was achieved by parallel plating. The osteotomy was routinely stabilized by tension band wiring with two parallel K-wires introduced up to the anterior ulnar cortex. The results were evaluated by the staging system of Caja et al. at a minimum follow-up of 2 years.Results:
In the first part of the study (n=94), there was delayed union in 4% (n=4), with the fracture taking more than 20 weeks for union. There was delayed union of ulnar osteotomy (n=3) and failure of one tension band wiring, requiring revision. Some loss of motion was seen in 20% of cases and these patients did not achieve full flexion and extension. However, all these patients had useful range of function, with 20°–110° of flexion and full pronation-supination. As per the staging system of Caja et al., the results were in the range of excellent to good in 72% cases (n=67), fair in 19% (n=18), and poor in 9% patients (n=9). In the second part of study (n=90) dual plate fixation of both columns by orthogonal methods (n=80) and parallel plate fixation in 10 patients was performed. The results were excellent to good in 78 patients (86%).Conclusions:
The high rate of union can be achieved in complex intra-articular fractures of distal humerus if the proper principles of stable fracture fixation are followed, i.e., a posterior transolecranon approach and dual fixation of both columns and restoration of the continuity of articular surface. The stability achieved by this technique permits institution of early intensive physiotherapy to restore elbow function. 相似文献19.

Purpose
The management of proximal femoral deformity in fibrous dysplasia (FD) is a challenge to the orthopaedic surgeon. The purpose of this study was to analyze the various presentations of FD of proximal femur and the results of the various treatment modalities for the same.Methods
This is a retrospective cohort study of 23 patients (24 femora) with FD who underwent surgery for the proximal femur. The study sample included 14 males, nine females. Ten patients had a monostotic disease, eight patients had polyostotic disease, and five patients had McCune-Albright syndrome.Results
Group 1: shepherd crook deformity—included five patients who underwent femoral neck osteotomy. Four patients had intramedullary (IM) nailing with neck cross-pinning and all patients showed union. One patient was stabilized with external fixation, which failed. Group 2: nine patients (ten femora) presented with frank pathological fracture. Nine underwent fixation with IM nailing, one with locking plate and screws. Three patients had to undergo more than one procedure and all fractures showed good union. Group 3: nine patients who presented with bone cyst and pain. All patients underwent biopsy; four of them had curettage with bone graft.Conclusion
