Abstract
Conclusion: Despite the long history of surgical treatment in syndactyly repair, this reconstructive operation has still special complexities.
Materials and Methods: In order to evaluation of results of our surgical reconstructions, we studied 77 patients (40 boys and 37 girls) with hand syndactyly (mean age at operation: 5.8±4.3 years) in Imam Khomeini Hospital from 1994 to 2003. All of these patients had been operated by standard surgical methods. Post-operative complications and functional, sensational, and cosmetic results have been assessed by patient records and physical examination after an average follow-up of 4.6±2.1 years.
Results: Syndactylies were simple in 71 patients (92.2%), complex in 2 (2.6%), and mixed in 4 (5.2%). In 45 patients (58.4%), surgical repair had been performed without graft. The overall results of operations were good in 81.8%, moderate in 13%, and poor in 5.2%. The most common complications were: web migration in 9.1%, scar contracture in 7.8%, infection in 5.2%, necrosis in 3.9%, and angular deformity in 2.6%.
Conclusion: In this study we shown that the standard methods in our center for correction of syndactyly, at least in recent 10 years, have been efficient and with good results.

Abstract
Paget’s disease is a chronic non-metabolic bone disorder that is characterized by increased bone resorption, bone formation and remodeling. This unbalanced process may lead to osseous deformities, structural weakness and altered joint biomechanics all of which can make surgical reconstruction difficult. Although few patients with Paget’s disease ever require surgical treatment, successful surgical management of severe orthopaedic complications has improved the quality of life for these patients. Surgical options include osteotomy to restore long bone deformity and arthroplasty to correct altered joint mechanics. Patients are at increased risk for surgical complication such as blood loss and heterotopic bone formation. Issues relating to the surgical management of patients with Paget’s disease such as appropriate preoperative diagnosis, technical challenges of surgery, and strategies to improve the long-term outcome of surgical intervention are discussed.

Abstract
Background: A plan for management of infected arterial pseudoaneurysm has evolved from our experience with forty two cases of such aneurysms treated between 1378 and 1382.
Methods: Clinical data of 42 patients with femoral pseudoaneurysm resulting from addictive drug injection who presented in emergency department of Sina Hospital between 1378 and 1383 were retrospectively reviewed.
Results: All patients were men with the mean age of 36.9 years. Twenty eight patients were referred from other medical centers. The mean time of delay in presentation was 17.3 days. The mean duration of drug injection was 14 months. Primary repair and emergent vascular bypass were performed in 3(7.1%) and 2(4.8%) patients, respectively. 5(11.9%) patients undergone delayed revascularization. Thirty two (76.2%) patients returned to their normal lifestyle without any vascular bypass. One patient required amputation and one patient died due to sepsis and acute renal insufficiency.
Conclusion: Management of infected femoral pseudoaneurysms is simple ligation of the external iliac or femoral artery. When Doppler is not available “Operation Room and postoperative Direct Observation” is recommended in such patients to avoid unnecessary revascularization surgery.

Abstract
Background: Both isokinetic testing and functional tests are commonly used to evaluate anterior cruciate ligament reconstructed (ACLR) patients. The object of this study was to evaluate motor performance of the knee and determine the relationship of isokinetic test scores to scores on a variety of lower extremity functional tests.
Methods: Ten healthy subjects and eleven ACLR patients at least six months after surgery performed the following: knee isokinetic tests at 60 and 180 deg/sec three functional tests including leg vertical jump, single hop, and triple cross-over hop for distance. The International Knee Document Committee Subjective Knee Evaluation Form (IKDCSKEF) was used to score the self-assessment of each study participant. Paired T-test was used to compare the involved and uninvolved knee. Pearson correlation coefficients were used to determine the relationship between the scores on the isokinetic test and functional tests. Significance was determined by P<0.05.
Results: IKDCSKEF score was significantly lower in patients than control subjects. Quadriceps peak torque and functional test scores were significantly lower in the involved knee of the ACLR subjects compared to the uninvolved knee. Correlation coefficients of isokinetic peak torque to body weight and functional testing were not significant in patients or control subjects, whi1e the limb symmetry index (LSI) of the quadriceps isokinetics peak torque to body weight and the LSI of the functional tests were significant (r = 0.54 to 0.97).
Conclusion: These results indicate a significant relationship between the LSI of various functional tests and the LSI of isokinetic testing among ACLR patients. Thus, in situations where an isokinetic dynamometer is not available, the LSI of functional tests can be used to estimate quadriceps deficiency for ACLR patients.

Abstract
Background: Surgery operations are the fearful events among all other medical procedures.
This fear causes anxiety and stress which affects the outcome of treatments, recovery from
surgery and some maladaptive behaviors. To cope with surgery worries and minimize the
fear, it is important to study these fears and its associated factors. This study attempts to
explore the surgery worries and the associated factors among Iranian high school adolescents.
Methods: To measure surgery worries, high school adolescents of age 11-15 completed the
Child Worries Questionnaire (CPCI) adolescent form, and also answered the questions about
the 14 independent variables (sex, age, parents education and occupation, previous
hospitalization experience of child and immediate family and friends, number of
hospitalization during Child’s life long, previous surgery experience of child and her or his
immediate families, death of close friends in hospital). Multivariate regression method was
used for statistical analysis to determine the effective factors.
Results: The results of this study showed that the Iranian Adolescents have most worries
about the “Not being able to do the same things as before” and least worries about “What I
will feel during the anesthesia”. The factors associated with Surgery worries are parent’s
education (P=.021 for father and 0.049 for mother), adolescent previous experience and
number of hospitalizations (P=0.025 and P=0.008, respectively), the number of previous
hospitalizations (P=.003), previous experience of hospitalization of immediate family and
friends (P=0.035). The findings of this study have implications for parents, family, hospitals’
staff and care given.
Conclusions: It seems, according to the findings of this study, there should be a special
educational program for children who are going to be operated in a hospital ward to reduce
their worriships.

Abstract
Background: Hypopharyngeal cancer usually presents with cervical mass, hoarseness, radiated otalgia, and dysphagea in the advanced stages. Radical surgery followed by radiotherapy plays an important role in the treatment of patients with hypopharyngeal cancer. However, there is no general consensus as to which is the best method of reconstruction after surgical resection. The aim of this study was to evaluate the complications of pectoralis major myocutaneous flap (PMMF) and gastric pull-up (GPU) techniques to reconstruct a circumferential defect after laryngopharyngoeso- phagectomy.
Methods: We retrospectively reviewed the records of 64 patients who underwent radical surgery and reconstruction with either PMMF or GPU technique. Demographic characteristics, tumor location, proximal margin involvement, history of radiotherapy, presence of lymphadenopathy, cervical dissection, and postoperative complications such as fistula, anastomotic site stenosis, swallowing dysfunction, and stoma stenosis were compared between the two groups. Postoperative complications of the reconstruction methods were compared.
Results: A total of 64 patients, 43(67%) in GPU group and 21(33%) in PMMF group, were studied. The groups did not differ in demographic characteristics. The locations of the tumoral lesions were in larynx (n=7), proximal esophagus (n=5), posterior cricoid (n=5), pyriformis sinus (n=7), posterior wall (n=7), and miscellaneous (n=41). Six patients (6.3%) had proximal margin involvement, 19 patients (29.9%) had history of radiotherapy, 26 cases (40.6%) had lymphadenopathy, and 49 cases (76.5%) had cervical dissection. There was no significant difference between the two groups regarding stenosis or swallowing dysfunction rates, but fistula was seen lower following GPU compared with PMMF (p<0.001).
Conclusions: The GPU technique results in similar functional stenosis or swallowing dysfunction rates, but lower fistula compared with PMMF reconstruction.

Abstract
Background: Several therapeutic modalities have been cited for patients with microtia. Recently there are several reports about using cadaveric homograft cartilage for some other purposes. The aim of this study was to assess the results of auricular reconstruct-tion in 10 patients (12 ears) with congenital atresia using homograft rib cartilage from the Iranian Tissue Bank.
Methods: We enrolled 10 patients with microtia who were referred to the Imam Khomeini Hospital from September 2006 to July 2007 for auricular reconstruction. The reconstruction was performed using a pre-shaped homograft(s) of each patient's ear(s) made by the Iranian Tissue Bank from the 6th, 7th and 8th costal cartilage according to the method of Marquette. In six patients, the second stage of reconstructive surgery was performed three months after the first stage. The patients were followed regarding the ear appearance, the dimensions of cartilage and tissue reaction.
Results: The mean age of the patients was 11.08 (SD=5.57) years and the average duration of follow-up was 6.29 (SD=3.12) months. Eight cases had unilateral involvement (six right and two left), in addition to two cases of bilateral involvement. During the follow-up period, the appearance of the helix was satisfactory in 11 ears and the lobule in 10 ears. The height and width of the reconstructed auricles was an average of 1-2 millimeters different from the opposite ear. Erythema was the most common early complication. Late complications, including cartilage exposure and infection, were observed in one patient.
Conclusion: Auricular reconstruction using homograft costal cartilage in patients with microtia has promising results. The short term resorption can be ignored and significant early or late complications are infrequent.

Abstract
Background: Anterior Cruciate Ligament (ACL) is one of the main knee stabilizing ligaments. Because of high incidence of ACL tearing especially in young athletes its reconstruction is very important. The aim of this study was to evaluate short-term results of anterior cruciate ligament ruptures using four strand hamstring auto graft and Bone patellar tendon autograph.
Methods: The study group included 96 patients (3 female and 93 male) with ACL teared who had been referred to our center in 5 years period (2002-2007). The subject which were Accessed in this study included meniscal injury concomitant chondral injury, determine the most common cause of ACL tearing, comparision of IKDC and lysholm score in all patients before and after surgery, and limitation of rang of motion of knee post operation.
Results: Involvement was in the right knee in 38 patients and in the left knee in 58 patients. Mean age of patients was 27.6 years (19-48). Mean surgical delay was 18 month (1-77). The most common cause of tear was playing soccer. Meniscal injury was in 78 patients. (Medial meniscus in 63 patients, lateral meniscus in 29 patients) Concommitent chondral injury was in 54 patients (56.25%). 68% of patients returned to preoperative functions sport activity. There was no limitation in extension and there was 6 patients limitation in flexion about 20º. In last visit of patients IKDS in class A and B was 96.
Conclusion: It is seem that arthroscopic reconstruction of ACL is a safe and good method in treatment of Knee stability. Use of IKDC and lysholm score for comparision of patients before and after surgery is helpful. The operation should be done early after injury. Reconstruction of ACL in older patients in the abscense of DJD is effective.

Abstract
Background: One of the most common orthopedic complaints is direct or indirect trauma to the knee with torn anterior cruciate ligament (ACL). Reconstruction of the torn ACL is emphatically offered in active individuals as by this operation, we prevent osteoarthritis, knee instability and injury to the meniscus. There are numerous methods for graft fixation in the femoral tunnel in ACL reconstruction. If the graft proves to be stable after the operation, patients would not complain of giving way knee joints. In this clinical trial, we compared transfemoral pinning with endobutton fixation of hamstring graft in arthroscopic ACL reconstruction by examining knee stability and use of other relevant functional tests.
Methods: Fourteen Patients who had undergone arthroscopic ACL reconstruction in Shariati Hospital during the years 2008-2009 and were being followed up were evaluated at least 15 months post-operatively by physical examination and the use of an
arthrometer made by the Faculty of Mechanics of Sharif Technical University.
Results: The results showed that two out of seven patients in which their ACL had been reconstructed by hamstring graft fixation by endobutton technique, and in one out of seven patients who had undergone ACL reconstruction by hamstring graft fixation through transfemoral pinning, Lachmann test (in 25 position) was greater than 5 mm but there were not any complaints of giving way knee joints.
Conclusion: The clinical results of ACL reconstruction by transfemoral pinning technique seems to be superior to the reconstruction by endobutton technique.

Abstract
Background: Anterior cruciate ligament (ACL) reconstruction is a first choice treatment for ACL-deficient knees, and arthroscopic single-bundle reconstruction has been widely accepted around the world in this regard. Although, such single-bundle reconstructions result in sufficient knee stability in most cases, but some patients have not been satisfied with postsurgical results in both short-term and long term clinical studies. One of the reasons for these unsatisfactory results could be related to the fact that normal function of the native ACL has not been restored by the traditional ACL reconstruction which uses only a single-bundle graft. The natural ACL consists of a 3-dimensional structure with multibundle fascicles, which can be anatomically divided into 2 main bundles, the anteromedial (AM) and the posterolateral (PL) bundles named for the orientation of their tibial insertions. The purpose of the present study was to compare double-bundle and single-bundle ACL reconstruction.
Methods: Twenty-two patients with anterior cruciate ligament tear who were candidates for ACL reconstruction were enrolled in the study undertaken in Shariati Hospital from 2009 to 2010. Fourteen patients underwent single-bundle and 8 patients double-bundle ACL reconstruction. The patients were evaluated by arthrometer and physical examination in postoperation follow up visit at least 9 months after the operations.
Results: Four out of 14 patients with single-bundle reconstruction had knee joint translation greater than 5 mm but nobody had knee translation more than 5 mm in the double-bundle reconstruction group.
Conclusion: Double-bundle ACL reconstruction seems to be more stable than single-bundle ACL reconstruction.

Abstract
Background: The goal of this study was to evaluate, functional capacity of the knee in flexion and internal rotation after hamstring ligament harvest for Anterior Cruciate Ligament (ACL) reconstruction.
Methods: Fifty patients (male and 18-45 years old) with isolated ACL injury, randomly allocated in two equal groups (in one group, ACL reconstruction was performed with Tibialis Posterior allograft and in another group with quadruple hamstring ligament auto graft) and before and 6 months after surgery in both groups isokinetic flexion strength and isometric internal rotation strength of knee evaluated with Biodex System 4 dynamometer and rotational torque recorder, in order. Isokinetic flexion strength evaluated in sitting and prone position the later position was performed for deep flexion strength evaluation. Also subjective and objective assessment of all patients pre operatively and 6 months post operatively was documented with International Knee Documentation Committee (IKDC) questionnaire. In this study for first time, rotational torque strength of knee was recorded with new design measure, from isometric aspect and not isokinetic.
Results: Although significant improvements in IKDC scores, flexion and internal rotation capacity of the knee were observed in both groups, post operatively in respect to pre operatively there was no significant difference between 2 groups. (P<0.05 or more than 95% confidence Interval of the difference)
Conclusion: This study demonstrates that ACL reconstruction surgery, improves knee performance in flexion and internal rotation, regardless of hamstring tendon harvesting. Considering potential complications of allograft (for example: transfer of harmful diseases from donor to recipient), it is logical to use hamstring auto graft ligament for ACL reconstruction surgery. Because result of this study is not longstanding follow up and limited to male sex, for more worthfull conclusion, we suggest future study in both sex and with long duration of follow up.
