Objective
To analyse whether early post-operative full weight bearing following syndesmotic ankle fixation affected radiographic outcomes suggestive of diastasis.Design
Retrospective comparative cohort study over a two year period.Setting
Level 1 trauma centrePatients/Participants
152 consecutive patients sustaining an unstable ankle fracture requiring syndesmotic stabilisation were included. Exclusions were 49 patients who had trimalleolar fixation without syndesmosis screws, one patient who had concomitant ankle and talar fracture. Five patients were lost to follow up and eleven patients were followed up in other centres. A total of 86 patients were analysedIntervention
Protected or full weight bearing.Main Outcome Measurement
The primary outcome measure was early diastasis. The secondary outcomes were late diastasis, wound complications and re-operation. Analysis of variance was used for the predictor variable of weight bearing status. We assumed a priori that p values of less than 0.05 were significant.Results
Median age was 36 (IQR 30), with 54 males and 32 females. Median follow up was 12 weeks (IQR 6). There was no significant difference when comparing weight bearing status and change in radiographic measurements intra-operatively compared to 6 and 12 week follow up radiographs (tibiofibular clear space p?=?0.799, tibiofibular overlap p?=?0.733 and medial clear space p?=?0.261).Conclusion
After surgical stabilization of an unstable syndesmotic injury, full weight bearing did not lead to syndesmotic diastasis in the early post-operative period. Full weight bearing is recommended following ankle fixation which includes syndesmotic fixation. 相似文献2.
Background
Few methods have been described for measuring hindfoot alignment from an anteroposterior view. The objective of this study was to compare two methods of angular measurement based on the views of Meary and Saltzman.Methods
Thirty asymptomatic volunteers were included. Four radiographs were performed: the views of Meary and Saltzman with parallel feet and with the Fick correction. The reproducibility was determined by the inter- and intraobserver variability (ICC).Results
Meary’s method revealed a mean valgus angulation of 3.9° (SD 3.47°). The reliability was extremely variable with a mean ICC of 0.59. The best reproducibility was obtained with Meary’s method with and without Fick correction.Conclusion
The results of this study show that the reliability of the angular measurements depends on the radiographic view and measurement method chosen. The lateral Fick correction did not counteract the influence of tibial rotation. The same method should be used consistently. 相似文献3.

Background
Our aim was to determine whether plasma levels of Tissue Factor (TF), Vascular Cell Adhesion Molecule 1 (VCAM-1), Interleukin 6 (IL-6) or D-dimer after foot and ankle injury could predict which patients would develop deep vein thrombosis (DVT).Methods
Patients aged 18–60 years with acute foot and ankle injury had venous blood sample to measure TF, VCAM-1, IL-6 and D-dimer within 3 days of injury. Patients had bilateral lower limb venous ultrasound to assess for DVT on discharge from clinic.Results
21 of 77 patients were found to have DVT (27%). There was no statistically significant association between levels of TF, VCAM-1, IL-6 or D-dimer and subsequent development of DVT.Conclusion
Tissue Factor (TF), Vascular Cell Adhesion Molecule-1 (VCAM-1), Interleukin-6 (IL-6) and D-dimer levels were not associated with development deep vein thrombosis in patients with acute foot and ankle injury. 相似文献4.

Background
Periprosthetic cystic osteolysis is a well-known complication of total ankle replacement. Several theories have been proposed for its aetiology, based on individual biomechanical, radiological, histopathology and outcome studies.Methods
Studies that met predefined inclusion/exclusion criteria were analysed to identify literature describing the presence of peri-prosthetic ankle cystic osteolysis. Quantitative data from the selected articles were combined and statistically tested in order to analyse possible relations between ankle peri-prosthetic bone cysts and specific implant characteristics.Results
Twenty-one articles were elected, totalizing 2430 total ankle replacements, where 430 developed peri-prosthetic cystic osteolysis.A statistically significant association (P < .001) was found between the presence of bone cysts and non-anatomic implant configuration, hydroxyapatite-coating, mobile-bearing and non tibial-stemmed implants. No significant association existed between the type of constraining and the presence of cysts (P > .05).Conclusions
Non-anatomic, mobile-bearing, hydroxyapatite-coated and non tibial-stemmed total ankle replacements are positively associated with more periprosthetic bone cysts. 相似文献5.

Objectives
Hip dislocations are highly morbid injuries necessitating prompt reduction and post-reduction assessment for fracture and incarcerated fragments. Recent literature has questioned the need for initial pelvic radiographs for acute trauma patients, resulting in computed tomography (CT) scans as the initial evaluation. This study investigates the relationship between choice of pre-reduction imaging and treatment of acute hip dislocations.Design
Retrospective Case-Control.Setting
Single Academic Level I Trauma Center.Methods
All acute hip dislocations from 2011 to 2016 were reviewed. Exclusion criteria were diagnosis of dislocation at another facility, death prior to reduction, emergent surgical or ICU intervention, and periprosthetic dislocation. Patients were grouped by those with only a radiograph prior to reduction, Group I, versus those with a pre-reduction CT scan, Group II. The primary outcomes were time to reduction and the acquisition of a second CT scan.Results
Of the 123 hip dislocations identified, 35 patients were excluded, mostly for transfer with a known dislocation. Group I included 29 patients and Group II included 59 patients. The mean time to reduction was 74?min in Group I and 129?min in Group II for a difference of 55?min (p?<?0.001). The rate of repeat CT scan was 0 in Group I versus 48 (81%) in Group II (p?<?0.001).Conclusion
Initial trauma pelvic radiography prior to CT is still important in the setting of suspected hip pathology to decrease time to hip reduction and unnecessary radiation exposure.Level of evidence

Background
This study reports the outcome of a plating system for arthrodesis of the first metatarsophalangeal joint (1st MTPJ) that incorporates a lag compression screw within a low profile titanium plate with a predetermined contour. This is the first report of the outcomes of this implant from a non-affiliated centre.Patient and methods
This is a prospective cohort study of 40 consecutive primary 1st MTPJ arthrodesis procedures. The mean age of the cohort was 56 years (range, 20–74 years). The diagnosis was hallux rigidus in 31 patients and inflammatory arthropathy in 7 patients.Results
All patients achieved clinical union at 6 weeks and radiological union was confirmed on plain radiographs between 6–16 weeks. One case of hardware removal was reported.Conclusion
The cohort achieved consistently satisfactory results with a reliable and reproducible MTPJ position and a 100% union rate. There was a low rate of hardware removal.Level of evidence

Introduction
Surgery or trauma may induce extensive arthrofibrosis around joints and tendon for the restrictive range of motion. Although some approaches were proposed, this problem is not solved satisfactorily. Extracorporeal shock wave therapy (ESWT) has been used for orthopedic, musculoskeletal, and fibrotic disorders. Whether it could prevent the formation of arthrofibrosis during the joint repair is unknown.Methods
Intra-articular adhesions were created in the right knee of the rabbit by cortical bone shaving and subsequent cast immobilization. Arthrofibrosis in the control and ESWT group was evaluated and compared at week 4.Results
Macroscopic score of arthrofibrosis and contracture angle of the control group are significantly higher. Histologically, the apparent gap between patella and tibia, loose connective tissue, and much less density of the blood vessel are found in the ESWT group.Conclusions
ESWT could noninvasively, effectively, and safely prevent the formation of arthrofibrosis during the knee repair. 相似文献8.

Background
Although various minimally invasive procedures for chronic ankle instability are increasingly being used, a question regarding whether these procedures can be a viable alternative of the modified Broström procedure remains controversial. This study was conducted to compare the intermediate-term clinical outcomes between lateral ligaments augmentation using suture-tape and modified Broström repair in a selected cohort of patients.Methods
Sixty female patients with chronic lateral ankle instability were randomly assigned and underwent surgical treatments by one surgeon. Twenty-eight patients with suture-tape augmentation and 27 modified Broström procedures were followed ≥2 years and analysed in this comparative study. The clinical evaluation included the Foot and Ankle Outcome Score (FAOS), Foot and Ankle Ability Measure (FAAM), and stress radiographs. Medical expense related with operation was analysed to evaluate the cost-effectiveness.Results
There were no statistically significant differences in the clinical outcomes between two procedures based on FAOS, FAAM, recurrence rate of instability, and stress radiographs. Total medical expense was approximately 1.3 times more in the suture-tape group (P < 0.001), despite shorter operation time.Conclusions
Lateral ankle ligaments augmentation using suture-tape showed the similar clinical outcomes but low cost-effectiveness, as compared to modified Broström repair for young female patients with chronic ankle instability. 相似文献9.

Background
This study was performed to evaluate the intermediate-term clinical outcomes after proximal chevron osteotomy for hallux valgus in patients with generalized ligamentous laxity, and to determine the effect on postoperative recurrence of deformity.Methods
There were 23 cases in laxity group (Beighton score ≥5 points) and 175 in non-laxity group with a mean followup of 46.3 months. Clinical evaluation consisted of the AOFAS score, Foot and Ankle Ability Measure (FAAM), and radiographic measurement of hallux alignment. Risk factors associated with postoperative recurrence were evaluated using univariate analysis.Results
Recurrence rates were 21.7% in the laxity group and 17.1% in non-laxity group (P = .218). There were no significant differences in clinical and radiographic measurements at final followup between the 2 groups. Preoperative HVA and IMA were found to be predictive factors of recurrence (OR = 6.3, 4.2; P = .001, .018, respectively).Conclusion
There were no statistical differences in the clinical and radiographic outcomes between hallux valgus with and without generalized ligamentous laxity. Generalized ligamentous laxity demonstrated no definitive effects on postoperative recurrence of hallux valgus deformity. 相似文献10.

Background
Total ankle replacement (TAR) represents an alternative to fusion for the treatment of end-stage ankle osteoarthritis. The aim of the present study was to retrospectively assess the frequency of infections between TARs with anterior and lateral transfibular approach at 12-months follow-up.Methods
81 TARs through an anterior approach and 69 TARs through a lateral approach were performed between May 2011 and July 2015. We compared surgical time and tourniquet time, as well as superficial and deep infections frequency during the first 12 postoperative months.Results
In the anterior approach group, there were 3 (3.7%) deep infections and 4 (4.9%) superficial wound infections. In the lateral approach group, there were 1 (1.4%) deep infection and 2 superficial wound infections (2.9%). There were not statistically significant differences between the groups. There was a significant difference between anterior approach (115 minutes) and lateral approach group (179 minutes) in terms of surgical time (P < 0.001).Conclusions
The frequency of superficial and deep periprosthetic infections during the first postoperative year was not significantly different in the lateral approach group compared to the anterior approach group, despite the significantly longer surgical time in the lateral transfibular approach group. 相似文献11.

Background
The aims of this study were to identify the artery feeding the fifth metatarsal and determine how bunionette osteotomy could injure this vessel.Methods
The nutrient artery entering the fifth metatarsal was investigated in 10 adult cadaveric lower limbs by barium injection and enhanced computed tomography.Results
The nutrient artery entered the medial aspect of the fifth metatarsal around the junction of the middle and proximal thirds obliquely from a distal direction (mean?angle 36°) in the coronal plane in all cases; in the axial plane, the point of entry and direction of the artery was medial-plantar (mean?angle 49°).Conclusions
This report revealed direction and location of the nutrient artery entering the fifth metatarsal. 相似文献12.

Background
The purpose of this study is to develop a Dutch version of the Oxford Ankle and Foot Questionnaire for Children (OxAFQ-c) to allow evaluation of pediatric foot care.Methods
The OxAFQ-c was translated into Dutch, according to the ISPOR-guidelines. Children with different foot and ankle complaints completed the OxAFQ-c at baseline, after two weeks, and after 4–6 months. Measurement properties were assessed in terms of reliability, responsiveness, and construct validity.Results
Test–retest reliability showed moderate intraclass correlation coefficients. Bland–Altman plots showed wide limits of agreement. After 4–6 months, the group that experienced improvement also showed improved questionnaire outcomes, indicating responsiveness. Moderate correlation between the OxAFQ-c and the Kidscreen and foot-specific VAS-scores were observed, indicating moderate construct validity.Conclusions
The Dutch OxAFQ-c showed moderate to good measurement properties. However, because we observed limited sensitivity to changes and wide limits of agreement in individual patients, we think the questionnaire should only be used in groups. 相似文献13.

Background
The purpose of this study was to investigate the test–retest reliability of the Phi angle in patients undergoing total ankle replacement (TAR) for end stage ankle osteoarthritis (OA) to assess the rotational alignment of the talar component.Methods
Retrospective observational cross-sectional study of prospectively collected data. Post-operative anteroposterior radiographs of the foot of 170 patients who underwent TAR for the ankle OA were evaluated. Three physicians measured Phi on the 170 randomly sorted and anonymized radiographs on two occasions, one week apart (test and retest conditions), inter and intra-observer agreement were evaluated.Results
Test-retest reliability of Phi angle measurement was excellent for patients with Hintegra TAR (ICC = 0.995; p < 0.001) and Zimmer TAR (ICC = 0.995; p < 0.001) on radiographs of subjects with ankle OA. There were no significant differences in the reliability of the Phi angle measurement between patients with Hintegra vs. Zimmer implants (p > 0.05).Conclusions
Measurement of Phi angle on weight-bearing dorsoplantar radiograph showed an excellent reliability among orthopaedic surgeons in determining the position of the talar component in the axial plane.Level of evidence: Level II, cross sectional study. 相似文献14.

Background
We report our experience with the Minimally Invasive Chevron Akin (MICA) technique for correcting hallux valgus, and evaluate its effectiveness and associated complications.Methods
Case series of 13 feet with mild to moderate symptomatic hallux valgus treated surgically from July 2013 to December 2014, with at least 48-months follow-up. Patients were assessed pre-operatively and post-operatively with radiographical measurements (Hallux Valgus Angle (HVA) and Intermetatarsal Angle (IMA)) and clinical scores (American Orthopaedic Foot and Ankle Society (AOFAS), 36-Item Short Form Health Survery (SF-36), Visual Analog Scale (VAS)).Results
Mean HVA and IMA decreased from 30.4° and 13.9°–10.9° and 10.2° respectively (p < 0.05). The mean AOFAS score improved from an average of 59.0–93.7 (p < 0.05). All patients reported a VAS score of 0 post-operatively, and the 4 SF-36 domains improved significantly (p < 0.05).Conclusions
The MICA technique is a safe and effective method in the surgical correction of mild to moderate hallux valgus deformity, and continued use is justified. 相似文献15.

Background
Infection after foot and ankle fractures is a major concern for orthopedic surgeons. It is widely believed that final osteosynthesis should be delayed until the infection is cured. However, there is no literature that supports this practice. In addition, the delay impairs patient function and quality of life (QoL).Methods
In the present study, four cases of ankle infection treated with aggressive debridement, early fixation and antibiofilm antibiotics are described. It is thought that, like other implant related infections, ankle infections can be rapidly treated with the definitive fixation and by curing the infection to make for a fast recovery of QoL and function.Results
The infections were caused by MSSA and Pseudomonas aeruginosa in case 1, MSSA in case 2 and MRSA as well as K. pneumonia in case 3. Case 4 was a culture negative infection. They were susceptible to antibiofilm antibiotics (the gram-negative bacilli susceptible to ciprofloxacin and the gram-positive cocci susceptible to rifampicin). Cases 1, 3 and 4 were treated with a tibio-talo-calcaneal arthrodesis and case 2 was treated with a de-rotational fibular osteotomy and a medial closing wedge supramalleolar osteotomy. All cases improved at a median time of 4 weeks in terms of quality of life (SF-36) and function (AOFAS). At 2-years follow-up, no recurrence of infection was observed in any of the cases. All the cases achieved fusion or osteotomy healing at final follow-up.Conclusions
Early fixation after debridement combined with antibiofilm antibiotics can be performed in foot and ankle inflections to provide early recovery of QoL and function in patients. 相似文献17.

Background
Pain, deformity and instability are the main reasons for fusion of the tarsal joints, a triple arthrodesis. The short and midterm results show that mobility, function and satisfaction increase postoperatively. However, osteoarthritis (OA) of the adjacent ankle joint is described as a long-term complication. Alignment of the foot could be an influencing factor. The aim of this study was to examine whether malalignment after triple arthrodesis leads to a higher grade of OA at long-term follow-up.Methods
Between 1991 and 2002, 81 patients underwent a triple arthrodesis. Preoperatively, postoperatively, 3, 7.5 and 15 years after surgery, dorsoplantar (DP) and lateral X-rays were taken and used to evaluate the degree of OA and the geometry of the foot. The degree of OA was estimated using the Kellgren and Lawrence score. The geometry of the foot was assessed using Meary’s angle; a Meary’s angle exceeding 15° in DP and/or greater than ?5 to 5° from the lateral view was defined as malalignment. In addition to the radiological evaluation, clinical scores (FFI and AOFAS) were recorded.Results
Thirty-five patients (40 feet) were available for analysis 15 years after surgery. In 19 cases there was an increase in ankle OA following the operation. Eight feet showed malalignment on the lateral view and 28 on the DP view. There was no difference in both an increase of ankle OA or clinical outcome between correct aligned feet and feet classified as malaligned. Thirty-three patients with 38 treated feet stated that they would decide to undergo the treatment again. Two patients would not want to undergo the same surgery again. The patients were satisfied with the result of surgery, clinical scores improved after surgery and remained stable in the long-term.Conclusions
Triple arthrodesis is a salvage procedure in patients with a painful and deformed hindfoot and results in a clinically beneficial outcome, even 15 years after surgery. The present study did not show that malalignment after triple arthrodesis results in a higher grade of OA of the ankle joint in the long-term. The cause of the aggravation of OA is still not fully understood and needs further research. Nevertheless, clinical results are satisfying 15 years postoperatively. 相似文献18.
Background
The primary aim of this study was to present the incidence of clinically significant end stage osteoarthritis (cOA) after syndesmotic fixation of ankle fractures. The secondary aim was to and identify independent predictors of cOA.Methods
A retrospective review of consecutive patients presenting to a single University affiliated institution between March 2008 and May 2010 was undertaken. Inclusion criteria were ankle fractures with syndesmotic stabilisation. Patients were excluded if pre or postoperative radiographs were missing or were lost to follow up. Data were gathered regarding demographics, fracture pattern, fixation methods, reduction parameters, screw removal, revision surgery, complications and cOA up to seven years post injury.Results
Data were available for 120 patients (86%). In total, 13 patients (11%) developed cOA. Univariate analysis showed that increasing age, open fracture, malreduction of the syndesmosis, removal of symptomatic screws, revision surgery and complications were predictors of developing cOA. Cox regression analysis revealed increasing age (hazard ratio (HR) 1.09, p = 0.006), and malreduction (HR 45.5, p = 0.001) were independent predictors of developing cOA.Conclusions
Ankle fractures with syndesmotic stabilisation represent a severe injury with a high rate of cOA. The only modifiable risk factor for developing cOA in this large series of patients was radiological malalignment. When syndesmotic stabilisation is required, careful intraoperative assessment should be undertaken to ensure the syndesmosis is reduced. 相似文献19.

Background
Anatomic graft reconstruction of the anterior talo-fibular ligament is an alternative for patients who are bad candidates for standard procedures such as a Broström–Gould reconstruction (high-demand athletes, obesity, hyperlaxity or collagen disorders, capsular insufficiency or talar avulsions). The purpose of this study is to describe an all-inside arthroscopic technique for ATFL reconstruction, and the results in a series of patients with chronic ankle instability.Methods
We reviewed patients with chronic ATFL ruptures treated with an all-inside arthroscopic allograft reconstruction of the ATFL, with a minimum 2-year follow-up. Twenty-two patients with lateral ankle instability were included. Mean follow-up was 34 ± 2.5 months.Results
The mean AOFAS score improved from 62.3 ± 6.7 points preoperatively to 97.2 ± 3.2 points at final follow-up. Three patients suffered complications: one case each of ankle rigidity, superficial peroneal nerve injury and fibular fracture.Conclusions
Chronic ATFL injuries are amenable to all-inside arthroscopic allograft reconstruction fixed with tenodesis screws. This procedure simplifies other reported techniques in that it facilitates identification and bone tunnel placement of the talar ATFL insertion. 相似文献20.
