Methods: This was a cross-sectional electronic survey of Turkish Orthopaedic Surgeons who were active members of the Turkish Society of Children’s Orthopaedics (TSCO) and still managing the children’s fractures in their daily clinical practice. An initial e-mail including the electronic survey followed by three reminder e-mails was sent to 110 members, and then reminder telephone calls were made. Results: The survey response rate was 66/110 (60%). In recent years, a definitive trend to surgical treatment was not seen 98%, 77%, 39%, and 88% of the responders in the closed humerus, forearm, femur, and tibia mid-shaft fractures, respectively. Neither the years of expertise nor the intensity of daily pediatric patients of the participants did not affect the treatment trend in any fracture scenarios. The patient’s age was the most cited factor influencing the responders’ decisions on whether conservative or surgical treatment would be performed in each fracture scenario. The most cited lowest age limits for surgical treatment inclosed mid-shaft fractures of the humerus, forearm, femur, and tibia, were the adolescent age group, 10-12 years, six years, and ten years, respectively.

Methods: In this cross-sectional survey,120 residents who either resigned or transferred to other OT clinics between autumn of 2013 and spring of 2020 were included. They were asked to complete a questionnare which was sent via Whatssapp application or e-mail. The questionnare was comprised of 2 sections; Section A, which adressed resignation, consisted of 15 questions and Section B, which adressed transfer to another OT programme, consisted of 12 questions. Both sections had open ended and multiple choice questions. Results: Of 120 residents, 96 (6.6%) resigned and then transferred to another specialty, and 24 (1.6%) transferred to another orthopedics and traumatology clinic based on our review. The overall resignation rate as per the total quotas for orthopedics and traumatology residency from 2013 to 2020 was 8.2%. Of the 120 orthopedics and traumatology residents who were eligible for the survey, 83 (70%) completed the questionnaire. Sixty-one (60 males, 1 female; median age = 26 years; age range = 25-35) of 96 residents who resigned from the orthopedics and traumatology residency completed section A (the response rate was 63.5%); 22 (22 males; median age = 27.6 years; age range = 25-34) out of 24 residents who transferred to another orthopedics and traumatology clinic completed section B (the response rate was 91.6%). In section A, 40 out of 61 individuals (65.5%) preferred orthopedics and traumatology specialty as the first choice in TUS, and 34 residents (55.7%) reported not to have had enough information regarding the residency program before starting their clinics. In section B, out of the 22 residents, 13 (59%) stated that orthopedics and traumatology residency was not their first choice in TUS, and 18 (81.8%) reported not to have had sufficient knowledge about the preferred clinic. The most common reason for resignation or transfer to another specialty was heavy workload (n = 46, 74.19%), followed by excessive hours of work (n = 45, 72.58%). The most common reason for transfer to another orthopedics and traumatology clinic was drudgery (n = 10, 45.5%), followed by problems with the hierarchy in orthopedics and traumatology residency (n = 9, 40.9%).

Methods: Patients diagnosed with LCPD and treated conservatively were evaluated retrospectively; 39 hips from 35 patients were included. The treatment protocol consisted of intermittent manual traction, range of motion exercises, activity limitation, bed rest, NSAID (ibuprofen 100mg/5mL), and ASA (100mg/day) during attack periods. The treatment protocol was standardized, and an algorithm was established for all the patients. Results: The mean follow-up was 13.7 (range = 8-22) years. According to the Stulberg classification, 26 (67%) hips were good, 6 (15,3%) were fair, and 7 (17%) were poor. No activity-limiting pain was detected in any patient. The mean Harris score was 90.5 ± 5.3 for Stulberg type 1, 2, and 3 hips, but 84.2 ± 8.8 for Stulberg type 4 and 5 hips.

Methods: A mesh femur model was constructed using computed tomography (CT) images. Five different cortical impingement (CI) scenarios were designed: central model (CM), lateral CI (LCI), medial CI (MCI), anterior CI (ACI), and posterior CI (PCI). The fixation stability was evaluated by femoral head movement, stress, and elastic strain at the fracture site. The maximum stress on the femoral cortex and the implants were also measured. Results: The maximal femoral head movements were 3.11 mm in ACI and 2.91 mm in MCI. Among all CI models, the highest stress value at the fracture site was recorded in ACI (18.9 MPa), and the maximum stress on the femoral cortex was determined in ACI (114.3 MPa). The highest microstrain value at the fracture site was measured in MCI (599.1 μstrain). In all scenarios, maximum stress was located around the proximal hole of the nail. Conclusion: This study revealed that cortical impingement results in excessive loading on the retrograde femoral nail in managing distal femur fractures. MCI and ACI mainly cause this pathological loading. Problems related to supraphysiological loadings, such as implant failure and periprosthetic fracture, can be reduced by applying the nail in the central position.","PeriodicalId":7097,"journal":{"name":"Acta orthopaedica et traumatologica turcica","volume":"56 1","pages":"173 - 177"},"PeriodicalIF":1.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47931486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: This retrospective study included 22 patients (14 males, 8 females) who underwent open-wedge corrective osteotomy with bone grafting for a malunited distal radius fracture between January 2006 and December 2018 were enrolled. The mean follow-up duration was 57.2 weeks (SD 46.1, range 12-206). All the patients were then divided into 1 of the 2 groups based on the graft material used: autogenous bone graft group (n = 10, 5 males and 5 females) and allogenic bone graft group (n = 12, 9 males and 3 females). We introduced the “duration of union/correction gap ratio” to represent the healing potential of each graft materials. Radiologic parameters including initial correction gap, radial inclination, radial length, palmar tilt, and ulnar variance were also measured pre- and postoperatively. Functional outcomes were assessed by grip strength, range of motion, and the disability of the Arm, Shoulder, and Hand score. Results: Of the 22 patients, 16 (72.7%) achieved complete union within 12 weeks, 3 (13.6%) in over 12 weeks, and the other 3 (13.6%) showed nonunion. Excluding the 3 nonunion cases, the mean union duration was 10.6 weeks, and the mean correction gap was 10 mm. The mean correction gap was wider in the autogenous bone graft group, and the mean union duration was longer in the allogenic bone graft group. Autogenous bone grafts had a significantly lower duration of bone union/correction gap ratio than allogenic bone grafts (0.76 vs. 1.61, P < 0.001). According to the correction method (simple open-wedge corrective osteotomy vs. open-wedge corrective osteotomy OWCO), only duration of bone union/correction gap ratio reflected the actual difference between values. Conclusion: Despite autogenous bone graft donor site morbidities, in our study, autogenous bone showed better bone healing potential than allogenic bone. In terms of bone union, autogenous bone has the benefit of better union in larger gaps than allogenic bone. Surgeons can take advantage of the newly introduced “duration of bone union/correction gap ratio” to compare the bone healing potential by graft materials or surgical options.
