Abstract
Avascular necrosis (AVN), also called osteonecrosis, stems from blood supply interruption to the bone and is often idiopathic. It has risk factors like trauma, alcohol, and corticosteroids. AVN in the talus (AVNT) is less common than in the femoral head. Most cases of talar osteonecrosis are associated with trauma, while a smaller proportion is linked to systemic conditions such as sickle cell disease or prolonged prednisone use. Glucocorticoids are a key nontraumatic cause. We report a middle-aged woman with Cushing's syndrome symptoms, such as hypertension and moon face, since her youth. A few years ago, she experienced pain and swelling in her ankle, which was diagnosed as atraumatic AVNT and treated with hindfoot fusion. Years later, she was diagnosed with Cushing's disease caused by an adrenocorticotropic hormone (ACTH)-producing pituitary adenoma in laboratory tests and imaging, which was resected in 2020. She experienced significant weight loss, and her Cushing's syndrome symptoms were relieved after tumor resection. Mechanisms behind AVN in hypercortisolism involve fat cell hypertrophy, fat embolization, osteocyte apoptosis, and glucocorticoid-induced hypertension. Traditional X-rays may miss early AVN changes; MRI is preferred for early detection. Although there are some cases of femoral AVN caused by endogenous hypercortisolism in the literature, as far as we know, this is the first case of AVNT due to Cushing's disease. AVNT treatment includes conservative approaches, hindfoot fusion, and core decompression. Cushing's disease is a rare cause of AVNT, and a multidisciplinary approach aids in the rapid diagnosis of elusive symptoms.

Abstract
OBJECTIVE To compare the effects of ankle integral and conventional physiotherapy on pain, range of motion, balance, disability, and treatment effectiveness in patients with chronic ankle instability (CAI). DESIGN Two-arm, parallel-group, randomized, double-blind, controlled trial. PARTICIPANTS 60 patients with unilateral CAI. INTERVENTION integral physiotherapy (n = 30) or conventional physiotherapy (n = 30). OUTCOMES Visual Analog Scale (VAS), dorsiflexion and plantarflexion range of motion, Star Excursion Balance Test (SEBT), Single Leg Hop (SLH) test, Foot and Ankle Outcome Score (FAOS), Lower Extremity Functional Score (LEFS), global rating of change, were gathered pre and post-intervention. RESULTS The ANOVA results revealed statistically significant interaction for FAOS, and LEFS outcome measures (P < 0.05) and the mean change results showed there were a favorable clinical difference incline toward the integral group (meanintegral = 20.14 (14.95-25.37), meanConventional = 29.46 (24.09-34.83)). There were no interactions between group and time among other outcome measures (P > 0.05). The group main effect did not show any statistical significance (P > 0.05). CONCLUSION Hip strengthening and balance exercises added to ankle rehabilitation could be more favorable on improving the patients' functional ability.

Abstract
BACKGROUND The decision regarding total ankle replacement (TAR) is challenging in patients with inflammatory arthritis (IA) regarding more inferior bone quality, large bone cysts, and increased risk of infections. This systematic review and meta-analysis aimed to compare the functional outcome, revision rate, complication rate, and survival rate of TAR between IA (including rheumatoid arthritis [RA]) and noninflammatory arthritis (NIA) (primary and posttraumatic). METHODS After reviewing the full texts, 30 articles fulfilled all inclusion criteria from 1985 until 2021, comparing TAR results. The eligible studies included 5508 patients, of whom 1565 patients had IA and 3943 patients had NIA. At the time of surgery, the average age was 58 years in the IA group and 63 in the NIA group. The average follow-up was 67.2 months in the IA group and 67 months in the NIA group. The outcome measures were the American Orthopaedic Foot and Ankle Society (AOFAS) score and the rate of complications, revisions, and survival. RESULTS The mean final AOFAS score was 82 (95% confidence interval [CI]: 78-86) in the IA group and 83 (95% CI: 78-88) in the NIA group, with no significant difference. There was no significant difference in the mean preoperative to postoperative AOFAS score change between the IA and the NIA. The complication rate was 16% (95% CI: 9%-27%) in the IA group and 15% (95% CI: 8%-27%) in the NIA group with no significant difference. The revision rate was 12% (95% CI: 10%-15%) in the IA group and 13% (95% CI: 10%-18%) in the NIA group, which was significant (P = .04). There was no significant difference in the survival rate between IA and NIA. CONCLUSION Total ankle replacement is a safe procedure in inflammatory ankle arthritis, specifically in RA patients with relatively minor and major complications close to other reasons for ankle replacement. LEVELS OF EVIDENCE Level IV: prognostic.

The Impact of Lateral Decubitus vs. Beach Chair Positioning on the Clinical Outcome of the Patients with Isolated SLAP Type II Repair: A Systematic Review and Meta-analysis. THE ARCHIVES OF BONE AND JOINT SURGERY 2022; 10:847-857. [PMID: 36452424 PMCID: PMC9702021 DOI: 10.22038/abjs.2022.63501.3063] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 02/05/2022] [Accepted: 04/17/2022] [Indexed: 01/25/2023]
Abstract
BACKGROUND A superior labrum from anterior to posterior (SLAP) repairs can be performed in either beach chair (BC) or lateral decubitus (LD). The purpose of this study was to perform a systematic review and meta-analysis to compare the outcomes of surgical repair of type II SLAP injuries between the BC vs. LD positions. We hypothesized no statistically significant differences in the functional, pain, and motion outcomes between the BC vs. LD positions after type II SLAP repair. METHODS A comprehensive literature search was performed using MEDLINE, Scopus, Web of Science, Embase, and Cochrane to identify studies reporting outcomes after type II SLAP repair. Outcome measures consisted of pain using the visual analog score (VAS), range of motion (ROM), and functional scores, including the University of California at Los Angeles Shoulder (UCLA) score, American Shoulder and Elbow Surgeons (ASES), and Constant score. The outcomes were pooled and analyzed for eligibility and stratified into two subgroups for a random-effects model meta-analysis. RESULTS Of the 8,016 identified studies through a database search, 13 papers (378 patients) were eligible for statistical analysis in the BC and 10 articles (473 patients) were included in the LD group. The mean follow-up for BC and LD was 35 and 44 months, respectively. The SLAP repair in both positions demonstrated improvements in postoperative clinical outcomes and ROM. Comparing the two positions, the LD group demonstrated significantly greater improvements in VAS which contributed to better functional outcomes, while the BC group showed a significantly greater improvement in abduction. No other differences were identified including ASES, UCLA, and Constant score as well as remaining ROM. CONCLUSION Based on the findings of this systematic review and meta-analysis, both the BC and LD positions provide patients better outcomes following operative repair of type II SLAPs. While LD represented a better improvement in functional outcome measures, the BC position demonstrated better abduction with no other significant differences between both positions. An individualized approach to position selection concerning the patient's complaint (pain vs. motion) as well as the surgeon's discretion is recommended.

Role of Hip Arthroscopy in the Treatment of Avascular Necrosis of the Hip: A Systematic Review. THE ARCHIVES OF BONE AND JOINT SURGERY 2022; 10:480-489. [PMID: 35928908 PMCID: PMC9295586 DOI: 10.22038/abjs.2021.58534.2894] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 02/12/2021] [Accepted: 08/14/2021] [Indexed: 01/24/2023]
Abstract
BACKGROUND Avascular necrosis (AVN) or osteonecrosis of the femoral head occurs as a result of a vascular supply disruption that could lead to hip osteoarthritis. Recently, several joint-preserving procedures have been suggested to improve the outcome of AVN, including hip arthroscopy. This systematic review aimed to investigate the role of hip arthroscopy to preserve hip joints suffering from AVN. METHODS This review was conducted to collect data on hip arthroscopy from the available literature for the management of AVN. The collected articles included those that were focused mainly on the management of AVN assisted by arthroscopy and published up to 2020 that were searched in four databases using such keywords as "Avascular Necrosis", "AVN", and "Osteonecrosis" in combination with "Hip Arthroscopy" or "Arthroscopic Hip Surgery". RESULTS In total, 13 articles met the eligibility criteria, and no severe complications were reported after arthroscopy in patients with AVN. Moreover, the Harris scores were higher than 79 after the operation. The majority of the assessments showed that the use of arthroscopy was effective in the diagnosis and treatment of patients with AVN, except for one study, which had been performed on patients with stage IV AVN. CONCLUSION The findings supported the idea that hip arthroscopy is effective in the treatment of AVN. This approach is becoming more popular for the diagnosis and treatment of hip disorders.

Leech Therapy Protects Free Flaps against Venous Congestion, Thrombus Formation, and Ischemia/Reperfusion Injury: Benefits, Complications, and Contradictions. THE ARCHIVES OF BONE AND JOINT SURGERY 2022; 10:252-260. [PMID: 35514759 DOI: 10.22038/abjs.2022.55013.2736] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Accepted: 01/31/2022] [Indexed: 11/06/2022]
Abstract
The use of free cutaneous or myocutaneous flaps in some surgeries, especially in reconstructive surgeries, is routine and imperative; nevertheless, it is controversial because of fear of flap loss due to tissue congestion and partial or complete necrosis. Different mechanisms are discussed in this process, and based on the involved mechanisms, various agents and approaches are suggested for flap salvage. Among these agents and strategies, leech therapy (hirudotherapy) can be a valuable complementary treatment; however, in this way, full attention should be given to all beneficial and harmful aspects to reach the best results. This study included a literature review of the essential complications following free tissue transfer and explained the effects of leech therapy for the respective complications. Based on the review of the literature, the essential complications following free tissue transfer were (I) venous obstruction and congestion, (II) delay in blood flow reestablishment, (III) ischemia/reperfusion injuries, and (IV) thrombus formation. Leech therapy can protect free flaps against the mentioned complications as a complementary treatment. Leech therapy is an appropriate complement, however, not a definite approach for flap salvage. Therefore, in some patients, other alternative methods or even flap removal may be a better option.

Abstract
OBJECTIVE The current study assesses the effects of platelet-rich plasma-fibrin glue (PRP-FG) dressing along with oral vitamin E and C on wound healing and biochemical markers in patients with non-healing diabetic foot ulcers (non-healing DFU). METHODS This randomized controlled trial was performed on 25 patients with non-healing DFU. Patients were treated with PRP-FG dressing plus oral vitamin E and C (intervention group) or PRP-FG dressing plus placebo (control group) for 8 weeks. RESULTS Eight weeks after treatment, six wounds in the intervention group and two wounds in the control group were completely closed, and also wound size significantly reduced in both intervention and control groups (p < 0.05). This reduction in wound size was significantly greater in the intervention group compared to the control group (p = 0.019). Also, a significant decrease in prooxidant-antioxidant balance (PAB) , ESR, and hs-CRP was observed in the intervention group compared to the control group (p < 0.05). CONCLUSION Our results showed that PRP-FG dressing along with oral vitamin E and C could be used to increase wound healing in patients with non-healing DFU by enhancing the wound healing process and reducing oxidative stress. TRIAL REGISTRATION This trial is registered at ClinicalTrials.gov (CT.gov identifier: NCT04315909).

Rhenium-188 radiosynovectomy for chronic haemophilic synovitis: Evaluation of its safety and efficacy in haemophilic patients. Haemophilia 2019; 26:142-150. [PMID: 31814241 DOI: 10.1111/hae.13880] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2019] [Revised: 10/21/2019] [Accepted: 10/23/2019] [Indexed: 11/28/2022]
Abstract
INTRODUCTION Radiocolloids labelled with less costly and more accessible radionuclides such as rhenium-188 are of interest to developing countries compared with those labelled with rhenium-186 and yttrium-90. AIM This study was aimed to evaluate the efficacy and safety of radiosynovectomy using rhenium-188 in patients with chronic haemophilic synovitis and recurrent hemarthrosis. METHODS In this quasi-experimental prospective study, 20 haemophilic patients were evaluated at preinjection, and at 1, 3, 6 and 12 months after injection. Magnetic resonance imaging (MRI) was done to measure synovial thickness and to calculate Denver score. Joint radiographs were taken to measure the Pettersson score. The Gilbert questionnaire, Functional Independence Score in Hemophilia (FISH) and visual analogue scale (VAS) for pain were completed, and the number of bleeding episodes and factor consumption were recorded at each follow-up visit. RESULTS The number of bleeding episodes, the amount of factor consumption per month, VAS pain scores and synovial thickness decreased significantly over time (P < .05). Gilbert and FISH scores showed significant improvement (P < .001). However, Pettersson score and Denver score showed no significant changes after injection. Minor complications including temporary pain and swelling occurred in 20% of patients, and no major complication was observed after rhenium-188 injection. CONCLUSION Our results indicated high clinical impact, efficacy, safety and low invasion of rhenium-188 in radiosynovectomy of haemophilic patients. Considering the availability and relatively low cost of rhenium-188 in developing countries, this can be a good treatment option for haemophilic patients with recurrent hemarthrosis, particularly when the synovial hypertrophy is not massive yet.

Abstract
BACKGROUND Clinical assessment of hindfoot alignment (HA) in adult acquired flatfoot deformity (AAFD) can be challenging and weightbearing (WB) cone beam CT (CBCT) may potentially better demonstrate this three-dimensional (3D) deformity. Therefore, we compared clinical and WB CBCT assessment of HA in patients with AAFD. METHODS In this prospective study, we included 12 men and 8 women (mean age: 52.2, range: 20-88) with flexible AAFD. All subjects also underwent WB CBCT and clinical assessment of hindfoot alignment. Three fellowship-trained foot and ankle surgeons performed six hindfoot alignment measurements on the CT images. Intra- and Inter-observer reliabilities were calculated using intra-class correlation (ICC). Measurements were compared by paired T-tests, and p-values of less than 0.05 were considered significant. RESULTS The mean of clinically measured hindfoot valgus was 15.2 (95% confidence interval [CI]: 11.5-18.8) degrees. It was significantly different from the mean values of all WB CBCT measurements: Clinical Hindfoot Alignment Angle, 9.9 (CI: 8.9-11.1) degrees; Achilles tendon/Calcaneal Tuberosity Angle, 3.2 (CI: 1.3-5.0) degrees; Tibial axis/Calcaneal Tuberosity Angle, 6.1 (CI: 4.3-7.8) degrees; Tibial axis/Subtalar Joint Angle 7.0 (CI: 5.3-8.8) degrees, and Hindfoot Alignment Angle 22.8 (CI: 20.4-25.3) degrees. We found overall substantial to almost perfect intra- (ICC range: 0.87-0.97) and inter-observer agreements (ICC range: 0.51-0.88) for all WB CBCT measurements. CONCLUSIONS Using 3D WB CBCT can help characterize the valgus hindfoot alignment in patients with AAFD. We found the different CT measurements to be reliable and repeatable, and to significantly differ from the clinical evaluation of hindfoot valgus alignment. LEVEL OF EVIDENCE Level II-prospective comparative study.

Abstract
AIM To evaluate the reliability of ankle syndesmotic measurements and their changes during active motion using four-dimensional computed tomography (4DCT) examination in asymptomatic ankles. MATERIALS AND METHODS 4DCT was performed on both ankles of patients with signs and symptoms of unilateral ankle instability. Ankles from the asymptomatic side of 10 consecutive patients were included in this analysis. Five ankle syndesmotic measurements were adopted from the available literature and performed by two fellowship-trained foot and ankle surgeons: (1) syndesmotic anterior distance (SAD); (2) syndesmotic posterior distance (SPD); (3) syndesmotic translation (ST); (4) syndesmotic tibiofibular angle (STFA); and (5) ankle tibiofibular angle (ATFA). A Monte Carlo simulation was also performed to obtain exact p-values with 99% confidence intervals. RESULTS Excellent interobserver reliability was observed among the two readers for four out of five measurements (intra-class correlation coefficients [ICC]: 0.767-0.995, p<0.001-0.020). The ICC values for SAD were not statistically significant (ICC=0.548 and 0.569 for dorsi and plantarflexion respectively, p=0.1). Among the five measurements, only ST measurements had significant changes during active motion (median [interquartile range] for change: -0.70 mm [-1.6-0.10]; p=0.012). Of the above measurements, only the ST measurements demonstrated a negative linear association with the tibiocalcaneal angle during active motion (beta=-2.5, p=0.04). CONCLUSIONS Reliable quantitative kinematic assessment of ankle syndesmosis can be performed using 4DCT examination. Syndesmotic measurements remain unchanged during ankle motion except for the syndesmotic translation, which tends to decrease during plantar flexion.

Abstract
BACKGROUND American Orthopedic Foot and Ankle Society Score (AOFAS) is a reliable and reproducible measurement tool which is commonly used for the assessment of foot and ankle conditions. In this study we aimed to translate and assess the psychometric properties of the Persian version of AOFAS questionnaire. METHODS In this study, we enrolled 53 patients with ankle and hindfoot conditions. Our study was conducted according to five staged cross-cultural adaption steps including translation, synthesis, back translation, expert committee review, and pretesting. After that reliability of the subjective parts calculated by Cronbach's alpha and the intraclass correlation coefficient (ICC) and the reliability of the objective items estimated using Cohen's kappa test. Also, construct validity was assessed by testing the Persian AOFAS against the SF-36 questionnaire. RESULTS Chronbach's alpha coefficient was 0.696, which was considered acceptable. Furthermore, the test-retest reliability measured by using the ICC for the subjective subscales was 0.853 (P<0.001). The reliability of testing the objective subscales was calculated by using Kappa, which indicated acceptable values. Pearson correlation coefficient between AOFAS and SF-36 was 0.415 (P=0.008). In addition, floor and ceiling effects were calculated 1.9% and 7.5% respectively. CONCLUSION In our study, Persian translation of AOFAS demonstrated acceptable validity and reliability with no need to be culturally adapted.

Abstract
About 15 % of all musculoskeletal tuberculosis (TB) have hip involvement. Early anti-tubercular drug therapy and other conservative treatment including short-term traction and mobilization programs could prevent hip joint destruction. Reactivation of TB accounts for a significant of active TB incidence, especially in the developed countries with a low TB prevalence. The risk of TB activation for population with the latent form of disease is about 5-10%. According to the existing literature surgery in tubercular hip arthritis would be safe once sufficient debridement and precise anti tubercular chemotherapy has been done.

Abstract
Background: This study aimed Persian translation and validation of the hip disability and osteoarthritis outcome score (HOOS) questionnaire. Methods: The study was carried out in two phases. First, we translated the HOOS according to acceptable guidelines. We assessed HOOS content convergent validity on 203 hip osteoarthritis patients using SF-36. Internal consistency was tested using Cronbach's alpha coefficient if each item removed and intraclass correlation coefficient (ICC) for the assessment of test-retest reproducibility. Results: Patients had mean (standard deviation) age of 39 (17). Test-retest ICC in whole was 0.95 (P = 0.014) showing excellent reliability. ICC was 0.92 for the “pain” subscale (P = 0.02), 0.81 for the “symptom” subscale (P = 0.002), 0.81 for the “function of daily living (FDL)” (P = 0.022), 0.88 for the “function of sports and recreational activities” (P = 0.006), but it was 0.62 (P = 0.1) for the “quality of life (QOL).” Cronbach's alpha was 0.92, 0.73, 0.97, 0.86, 0.80, and 0.80 for the pain, symptom, FDL, function of sports, QOL, and stiffness, respectively, showing good to excellent internal consistancy. Having SF-36 for the assessment of convergent validity, there was a strong correlation between total HOOS score and the physical component summary domain of SF-36 (r = 0.64, P = 0.0001), whereas the t correlation with the mental component summary domain was weak (r = 0.16, P = 0.04). Conclusions: The Persian version of the HOOS questionnaire is a valid (regarding physical not mental aspects) and reliable assessment tool in patients with hip osteoarthritis.

Abstract
Bone disorders are of significant worry due to their increased prevalence in the median age. Scaffold-based bone tissue engineering holds great promise for the future of osseous defects therapies. Porous composite materials and functional coatings for metallic implants have been introduced in next generation of orthopedic medicine for tissue engineering. While osteoconductive materials such as hydroxyapatite and tricalcium phosphate ceramics as well as some biodegradable polymers are suggested, much interest has recently focused on the use of osteoinductive materials like demineralized bone matrix or bone derivatives. However, physiochemical modifications in terms of porosity, mechanical strength, cell adhesion, biocompatibility, cell proliferation, mineralization and osteogenic differentiation are required. This paper reviews studies on bone tissue engineering from the biomaterial point of view in scaffolding. Level of evidence: I.

Abstract
Category: Hindfoot Introduction/Purpose: Assessment of hindfoot alignment in adult acquired flatfoot deformity (AAFD) can be challenging. Clinical judgment and radiograph studies while important may not represent the accurate valgus alignment of the affected patients. Weightbearing (WB) ConeBeam CT (CBCT) is an emerging imaging modality that may potentially better demonstrate the three-dimensional (3D) deformity, facilitating visualization of important soft-tissue and bony landmarks and helping in surgical planning. Based on the relative position of bone and soft-tissue axes, different measurements of hindfoot alignment can be obtained with CT images. Therefore, we compared clinical assessment of hindfoot valgus alignment in AAFD patients with different possible measurements performed on WB CBCT images. Methods: In this prospective, IRB-approved study, 20 patients (20 feet, 15 right and 5 left) with clinical diagnosis of flexible AAFD were included. There were 12 males and 8 females, with a mean age of 52.2 years (range, 20 – 88 years of age), and average BMI of 30.35 kg/m2 (range, 19.00 – 46.09 kg/m2). Patients underwent clinical assessment of hindfoot alignment as well as WB CBCT. Two independent and blinded foot and ankle board-certified surgeons performed different hindfoot alignment measurements on the WB CBCT images that included: 3D “clinical” alignment; Achilles tendon axis/calcaneal tuberosity angle; angles formed between the tibial axis and the calcaneal tuberosity, calcaneal axis and line connecting midpoint of subtalar joint and most inferior part of calcaneal tuberosity. Positive values were considered valgus alignment. Mean differences between the measurements modalities were compared by paired T-test. Intra- and Inter-observer reliability for the WB CBCT measurements were calculated using Pearson correlation. Results: The mean clinical hindfoot valgus measured was 15.15o (SD 7.7o). It was found to be significantly different from the mean values of all WB CBCT angles modalities: 3D “clinical” alignment (10.42o, p < 0.015); Achilles tendon/calcaneal tuberosity angle (2.96o, p < 0.0001); tibial axis/calcaneal tuberosity angle (5.42o, p < 0.0001); tibial axis/subtalar joint angle (7.52o, p < 0.0001) and tibial axis/calcaneal axis angle (20.39o, p < 0.017). We found an excellent intra-observer agreement for all WB CBCT 3D measurements (range, 0.8863 – 0.9713, p < 0.0001). There was also good to excellent inter-observer reliability, with the exception of the 3D “clinical” alignment (r=0.450, p < 0.04), that showed moderate correlation. Conclusion: The use of 3D WB CBCT imaging can help characterize the valgus hindfoot alignment in patients with adult acquired flatfoot deformity. We found the different CBCT measurements modalities to be reliable and repeatable, and to significantly differ from the clinical evaluation of hindfoot valgus alignment.

Translation and cultural adaptation of the Manchester-Oxford Foot Questionnaire (MOXFQ) into Persian language. Foot (Edinb) 2015; 25:224-7. [PMID: 26365951 DOI: 10.1016/j.foot.2015.07.004] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2015] [Revised: 06/22/2015] [Accepted: 07/06/2015] [Indexed: 02/04/2023]
Abstract
PURPOSE In this study, we aimed to translate and test the validity and reliablity of the Persian version of the Manchester-Oxford Foot Questionnaire in foot and ankle patients. METHODS We translated the Manchester-Oxford Foot Questionnaire to Persian language according to the accepted guidelines, then assessed the psychometric properties including the validity and reliability on 308 patients with long-standing foot and ankle problems. To test the reliability, we calculated the intra-class correlation coefficient (ICC) for test-retest reliability and measured Cronbach's alpha to test the internal consistency. To test the construct validity of the Manchester-Oxford Foot Questionnaire we also administered the Short-Form 36 to patients. RESULTS Construct validity was supported by significant correlation with SF36 subscales except for pain subscale of the persian MOXFQ with mental health of the SF36 (r=0.207). Intraclass correlation coefficient was 0.79 for the total MOXFQ and ranged from 0.83 to 0.89 for the three subscales. Cronbach's alpha for pain, walking/standing, and social interaction was 0.86, 0.88, and 0.89, respectively, and was 0.79 for the total MOXFQ showing good internal consistency in each domain. CONCLUSION The Persian Manchester-Oxford Foot Questionnaire health scoring system is a valid and reliable patient-reported instrument for foot and ankle problems.

Hip Arthroplasty and its Revision in a Child: Case Report and Literature Review. THE ARCHIVES OF BONE AND JOINT SURGERY 2015; 3:207-11. [PMID: 26213707 PMCID: PMC4507076] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 12/20/2014] [Accepted: 03/30/2015] [Indexed: 03/26/2024]
Abstract
Juvenile idiopathic arthritis is the leading cause of hip replacement in young children. However, arthroplasty in this population is challenging with several concerns about quality of the growing bone, young age for revision surgery, and difficulties in potential several revisions. In this study we introduce a case of a 12-year old who is one of the youngest patients to undergo revision hip arthroplasty. The index operation was done as a hybrid replacement, cemented for stem and press fit for acetabular component. Two years later revision was done with severe femoral deficiency. This second procedure was challenging but with short-term promising results. So we reviewed the literature for arthroplasty in this young population regarding recent findings and trends. According to the literature survival of the prosthesis is longer with a cemented acetabular component and press fit stem; however, there are evidences that show poor outcome of joint replacement after the first revision in juvenile idiopathic arthritis patients.

Anterior ankle arthrodesis with molded plate: technique and outcomes. THE ARCHIVES OF BONE AND JOINT SURGERY 2014; 2:203-209. [PMID: 25386583 PMCID: PMC4225027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 06/22/2014] [Accepted: 08/17/2014] [Indexed: 06/04/2023]
Abstract
BACKGROUND There is still controversy regarding the best technique for ankle arthrodesis to acheive stable rigid fixation along with reconstructing a functional plantigrade foot. Moreover, existing techniques have complictions related to stability, soft tissue covering, fusion rate, and exposure. METHODS With the anterior approach exactly on the tibialis anterior sheath, the joint was exposed and previous hardware, if any, was removed and with the safe direct approach, the ankle, hindfoot, and indirectly the subtalar joints were accessed. Then fresh cancellous bone was obtained and complete denudation was preformed. Lastly, a narrow 4.5 millimeter plate was carefully placed on what was determined to be the best final position.In this prospective study, 12 patients with severe ankle pain and arthritis enrolled from February 2010 to January 2012. Eight of them had posttraumatic arthritis and deformity with hardware, two had rheumatoid arthritis, one had poliomyelitis with severe deformity of the foot and knee, and another had chronic ulcerative synovitis of the ankle joint. The patients were assessed clinically and radiographically for an average of two years (range: 13 months to 4 years) for functional recovery, range of motion, stability of the ankle, and imaging evidence of union. RESULTS Ankle deformities and pain in all 12 cases were corrected. With a short healing time and rapid recovery period, after six weeks all of the patients could walk independently. Also, scores of the Manchester-Oxford Foot Questionnaire (MOXFQ) improved significantly from 69 preoperatively to 33 postoperatively). CONCLUSIONS Anterior ankle arthrodesis with molded plating can be an easy and safe way to manage deformities and it has excellent fusion rate and sufficient rigid fixation.
