RESUMEN

Introduction: The Judet and Letournel classification is the most widely used classification system for acetabular fractures. Some complex fractures couldn't be classified according to this classification. The main purpose of this study was to evaluate the reliability of the Letournel and Judet classification system for acetabular fractures. Material and methods: 10 acetabular fractures were analyzed among 17 orthopedic surgeons. The surgeons were asked to classify the fractures according to the Judet and Letournel classification. Their experience, the number of surgeries, and the incision type that the surgeon uses for the anterior part of the acetabulum were recorded. Results: The overall interobserver agreement for the Letournel classification was found to be poor, with a Kappa value of 0.287. The Kappa value for interobserver agreement was 0.224 for plain radiographs, 0.293 for 2D-CT, and 0.321 for 3D-CT scans. There was no significant difference between the incision types used by the surgeons. The highest reliability was determined among the surgeons who operate on 10-20 acetabular fractures per year, with a Kappa value of 0.309. Conclusion: This results revealed that the Judet and Letournel Judet classification is not sufficient to classify acetabular fractures because of unclassified fractures and the complex algorithm of the system. Level of Evidence III; Comparative Retrospective Study.


Introdução: A classificação de Judet e Letournel é o sistema de classificação mais amplamente utilizado para fraturas acetabulares. Algumas fraturas complexas, porém, não puderam ser classificadas de acordo com esta classificação. O principal objetivo deste estudo foi avaliar a confiabilidade do sistema de classificação de Judet e Letournel para fraturas acetabulares. Material e métodos: Foram selecionadas aleatoriamente 10 fraturas acetabulares de um banco de dados. Participaram do estudo 17 cirurgiões ortopédicos. Foi solicitado aos cirurgiões que classificassem as fraturas de acordo com a classificação de Judet e Letournel. Suas experiências, o número de cirurgias e o tipo de incisão que o cirurgião utiliza para a parte anterior do acetábulo foram registrados. Resultados: A concordância interobservadores geral para a classificação de Judet e Letournel foi considerada fraca, com um valor de Kappa de 0,287. O valor de Kappa para a concordância interobservadores foi de 0,224 para radiografias simples, 0,293 para tomografias computadorizadas em 2D e 0,321 para tomografias computadorizadas em 3D. Não houve diferença significativa entre os tipos de incisão utilizados pelos cirurgiões. A maior confiabilidade foi determinada entre os cirurgiões que operam de 10 a 20 fraturas acetabulares por ano, com um valor de Kappa de 0,309. Conclusão: Os resultados revelaram que a classificação de Judet e Letournel não é suficiente para classificar fraturas acetabulares devido a fraturas não classificadas e ao algoritmo complexo do sistema. Nível de Evidência III; Estudo Comparativo Retorpectivo.

RESUMEN

Introduction: To compare surgical and conservative management of midshaft clavicle fractures according with scapulothoracic joint angle change, considering clinical, functional, and radiological outcomes. Methods: A total of 95 midshaft clavicle fracture patients aged between 18-70 years with a minimum follow-up duration of 12 months were included in this study. Patients were treated either conservatively (Group I) or surgically (Group 2). Plane deformities, scapulothoracic joint angle, shortness and isokinetic muscle strength were measured. Shoulder Pain, Disability Index (SPADI) and Short Form-36 (SF36) were assessed. Results: Scapulothoracic joint angles were higher in the conservative treatment group than in surgery group (p=0.036). Consequently, winged scapula was seen more commonly in the conservative treatment group than in the surgery group (p=0.001). Surgical treatment was associated with significantly better SF-36 physical scores and with SPADI pain and disability scores. However, the two groups did not differ in terms of isokinetic muscle strength. Negative anteroposterior plane deformity (p<0.001) and negative axial plane deformity (p=0.004) were more frequent in the conservative treatment group. Clavicle shortness was more common in the conservative treatment group. Conclusion: According to our findings scapulothoracic joint angle changes were seen in the conservative treatment group more than in the surgery group. Consequently, winged scapula was seen more commonly in the conservative treatment group than in the surgery group (p=0.001). Level of Evidence III; Retrospective comparative study .


Introdução: Comparar o manejo cirúrgico e conservador das fraturas da diáfise da clavícula conforme alteração do ângulo escapulotorácico, considerando resultados clínicos, funcionais e radiológicos. Métodos: Um total de 95 pacientes com fratura do terço médio da clavícula com idade entre 18-70 anos, com um tempo mínimo de seguimento de 12 meses, foram incluídos neste estudo. Os pacientes foram tratados conservadoramente (Grupo I) ou cirurgicamente (Grupo 2). Deformidades planas, ângulo escapulotorácico, encurtamento e força muscular isocinética foram medidos. O Índice de Dor e Incapacidade do Ombro (SPADI) e a Short Form-36 (SF36) foram avaliados. Resultados: Os ângulos da articulação escapulotorácica foram maiores no grupo de tratamento conservador do que no grupo de cirurgia (p=0,036). Consequentemente, a escápula alada foi vista mais comumente no grupo de tratamento conservador do que no grupo de cirurgia (p=0,001). O tratamento cirúrgico foi associado a escores físicos SF-36 significativamente melhores e escores SPADI de dor e incapacidade. No entanto, os dois grupos não diferiram em termos de força muscular isocinética. A deformidade no plano anteroposterior negativo (p<0,001) e a deformidade no plano axial negativo (p=0,004) foram mais frequentes no grupo de tratamento conservador. O encurtamento da clavícula foi mais comum no grupo de tratamento conservador. Conclusão: De acordo com nossos achados, as alterações do ângulo escapulotorácico foram mais observadas no grupo de tratamento conservador do que no grupo de cirurgia. Consequentemente, a escápula alada foi vista mais comumente no grupo de tratamento conservador do que no grupo de cirurgia (p=0,001). Nível de Evidência III; Estudo comparativo retrospectivo .

RESUMEN

AIM: This study compared the results of tarsal tunnel syndrome release surgeries using mini-open incisions and standard incisions. PATIENTS AND METHODS: From January 2012 until April 2018, 31 feet of 29 patients diagnosed with tarsal tunnel syndrome were treated surgically. 15 feet of 15 patients underwent surgeries utilizing minimally open technique and 16 feet of 14 patients underwent surgeries utilizing standard incisions. The following preoperative and postoperative data was obtained: foot and ankle muscle testing results, posture analyses, anthropometric measurements, joint movement ranges, pain complaints, endurance evaluation results, and functional test results. The mean follow-up period was 38 months (13-88 months). RESULTS: The mean operation times were 26.8 min (23-30 min) using the standard incision and 13.3 min (9-17 min) using the mini-open incision (p < 0.05). In the preoperative and postoperative comparisons of the total muscle strength and total joint limit values of the healthy and affected feet, statistically significant improvements were observed in both the mini-open incision and standard incision groups (p < 0.05). Moreover, statistically significant improvements were seen in both groups in the postoperative repeated toe raises for 1 minute assessments of the affected foot (p < 0.05). In the foot function index and functional foot score values, statistically significant improvements were seen between the preoperative and postoperative values in both groups (p < 0.05). CONCLUSIONS: Based on the results of this study, using a tunnel ligament release instrument assisted minimally open surgery to loosen the laciniate ligament may present an alternative to the standard incision, with its significantly decreased morbidity rate and cosmetic success.

RESUMEN

OBJECTIVES: This study aims to investigate the reliability of the Lichtman classification among residents, orthopedic surgeons, and hand surgeons. MATERIALS AND METHODS: This study was carried out with 30 male observers (mean age 37.8 years; range, 26 to 62 years) who agreed to participate in the study. All observers were orthopedic surgeons. The observers were separated into three groups that consist of 10 residents, 10 orthopedic surgeons, and 10 hand surgeons. The anteroposterior and lateral wrist radiographs of 20 patients (12 males, 8 females; mean age 49 years; range, 38 to 74 years) diagnosed as Kienböck's disease were sent to observers via e-mail as a survey. All 40 radiographs were asked to be kept classified. RESULTS: The classification of Kienböck's disease was analyzed by 30 observers on 40 digital radiographs. The overall agreement with the Lichtman classification was fair within all of the observers (kappa=0.203). When groups were evaluated within themselves, the agreement level was found poor in group 1 (kappa=0.162) and fair in group 2 (kappa=0.210) and group 3 (kappa=0.252). CONCLUSION: A useful classification system in orthopedics and traumatology should classify the type of musculoskeletal disorder reliably, facilitate communication in clinical practice, guide preoperative planning, and enable comparison of results between studies. The Lichtman classification alone is insufficient and should be supported by other imaging and measurement techniques.

RESUMEN

OBJECTIVE: To evaluate trends in publications on unicompartmental knee arthroplasty (UKA) from the past to the present. METHODS: As a web-based analysis, all UKA research articles, editorial letters, case reports, reviews and meeting abstracts published on the Thomson Reuters' Web of Knowledge were evaluated. The period from the first publication in 1980 to January 2019 was divided into four decades and publications were evaluated. Research articles were grouped into headings according to the subjects. RESULTS: A total of 1,658 publications were evaluated in this study. The most frequent term used in the publications title was "outcome," with 260 items, followed by "biomechanics and kinematics," with 99 items. Most reports have been published in the last decade, and the most common type of publication was postoperative follow-up and results. CONCLUSION: In parallel with technological advancements, publications related to UKA-especially patient-specific instrumentation, navigation, and robotic surgery-will increase in number and become more specific. Level of Evidence V, Expert Opinion.

RESUMEN

Titanium alloy implants are the most used materials for the fixation of lower extremity fractures. Although these implants were thought to be inert materials in vitro, several studies have shown increased serum and remote tissue metal ion levels due to wear of implants and friction of the bone-implant interface in vivo. The aim of this study was to investigate the alteration of serum metal ion levels that are released from intramedullary nails and plates used for the fixation of lower extremity fractures, within the fracture healing period. The study included 20 adult patients, who were treated with intramedullary nail or plate osteosynthesis due to closed lower extremity fractures. Alterations of serum titanium, aluminum, molybdenum, and vanadium levels were evaluated at 6, 12, 18, and 24 weeks postoperatively. A statistically significant increase was determined in serum titanium, aluminum, molybdenum, and vanadium ion levels in the intramedullary nail and plate groups at the end of the follow-up period. Pairwise comparisons of metal ion levels between implant groups revealed no significant difference during a 24-week follow-up period. Compared to the control group, statistically significant increased levels of serum titanium, aluminum, vanadium, and molybdenum ions were determined in the implant groups used for the fixation of lower extremity fractures at the end of 24 weeks. In the current literature, the potential toxic effects of prolonged exposure to low levels of these metal ions are still unknown. It can be predicted that long-term metal ion exposure could result in vivo pathological processes in the future.

RESUMEN

OBJECTIVES: This study aims to clinically evaluate the efficacy of pedicle bone flap treatment in stage II Kienböck's disease. PATIENTS AND METHODS: This retrospective study included 10 patients (8 males, 2 females; mean age 33.3 years; range, 23 to 46 years) treated with pedicle bone flap between January 2012 and June 2016. In all patients, a fourth extensor compartment artery (ECA) pedicle bone flap from the dorsal surface of the radius was prepared and placed through a window opened on the lunate bone. Clinical results of the patients were evaluated according to the Mayo wrist score. RESULTS: All patients could return to their daily activities after surgery. No superficial or deep infection developed requiring debridement or antibiotic use other than prophylaxis. None of the patients required reoperation due to complications or the progression of the disease. The mean Mayo wrist score was measured as 81 (good). CONCLUSION: In this study, results of the fourth ECA pedicle bone flap application were found to be effective in the treatment of avascular necrosis of the lunate bone. Further comparative and long-term follow-up studies are required including large and homogeneous patient groups.

RESUMEN

Background/aim: The aim of this study is to compare the stability and implant stresses of suprapectineal plate with infrapectineal plate in three subconfigurations of the screw types. Materials and methods: The stabilities of different fixation methods were compared by finite element analysis on six models. Three infrapectineal and three suprapectineal models each with locked, unlocked, or combined screws were employed. Three-dimensional finite element stress analysis was performed by using isotropic materials with a load of 2.3 kN applied at standing positions. Motion at the fracture line was measured on four different points located on the pubic and iliac sides of the fracture line. Results: Infrapectineal plate fixation with unlocked screws was found to be the most stable fixation method with 0.006 mm displacement of fragments in all axes at standing positions. The suprapectineal unlocked method was found to be the most unstable in standing positions with maximum displacement values of 0.46 mm vertical shear movement in the x-axis, ­0.14 mm displacement in the y-axis, and ­0.33 mm lateral shear in the z-axis. Conclusion: The infrapectineal unlocked plate supplies the most stable fixation with the least implant stress, contrary to the suprapectineal unlocked plate, which has the lowest stability and highest implant stresses.

RESUMEN

BACKGROUND: To compare the union times of the uncomplicated tibial shaft fractures, which were distally locked by two coronal and one sagittal screws and by only two coronal screws. METHODS: 45 patients with tibial shaft treated with intramedullary nailing included in this study. 23 of 45 fractures were treated with uniplanar two distal interlocking (Group 1) and 22 fractures were treated with biplanar three distal interlocking (Group 2). Patients with closed fractures treated by closed nailing and having a full set of radiographs on PACS system was included. Fracture unions were evaluated by two authors. RESULTS: Union time was significantly shorter in biplanar distal interlocking group (Group 2) compared to uniplanar distal interlocking group (Group 1) (P=0.02). Mean union time in groups 1 and 2 were 14.63±4.5 and 10.77±3.0 weeks, respectively .When only distal third tibial shaft fractures were evaluated, Group 2 [11.2±3.1 weeks (n:17)] had significantly lower union time compared to Group 1 [15.07±4.8 weeks (n:14)] (P=0.01). Inter-observer reliability for fracture union times was high with rho= 0.89 with SE of 0.51 (P<0.001). CONCLUSION: Biplanar distal interlocking procedure had a significantly shorter union time. Biplanar distal interlocking procedure allows a faster fracture union probably because of a more stable fixation construct.

RESUMEN

Anterior cruciate ligament (ACL) injury is known to be one of the most common knee joint injuries. ACL reconstruction can be similar to the native ACL in respect of graft morphology, tension, position, and orientation. ACL reconstruction can be applied with different surgery techniques, graft and fixation devices, and rehabilitation as ACL reconstruction is just as important as surgery. Although commonly known as a sports injury, ACL injuries are increasingly seen in the general population. The aim of this study was to investigate the trends in ACL injury treatment in the last decade especially the graft choice. The abstracts of a total of 2,622 papers which stated ACL in the title were investigated through a search on the Web of Knowledge. Main topics were created as the ACL reconstruction theme. ACL reconstruction was examined in the abstracts with graft choice as the main theme followed by single bundle, double bundle, sports, rehabilitation, revision, complication, skeletally immature, biomechanics and kinematics, fixation devices, meniscus, anesthesia and pain, tunnel, cell, and intra-articular injection. Of the total 2,622 documents, 2,129 were original articles and 181 were reviews. Most of the documents, 436 in number (16.6%), were published in the American Journal of Sports Medicine, followed by the Journal of Knee Surgery, Sports Traumatology, Arthroscopy at 264. Of the total documents published, 36.3% were from the United States followed by 8.5% from Japan. The author with the most publications was F.H. Fu with 94 publications followed by B.R. Bach with 41 publications. The hamstring graft was most used at 187 single use and comprising 52% of the total graft combinations. Most papers were published in 2016. In 2012, single and double bundle grafts were determined to a total of 23. The most common title investigated in papers was biomechanics and kinematics with a total of 241 publications followed by rehabilitation at 208. Throughout the years of the study period, the most common graft choice was hamstring autograft. Biomechanics and kinematics was the most common title investigated as biomechanics and rehabilitation are known to be just as important as surgery for a successful outcome and patient satisfaction.

RESUMEN

BACKGROUND/AIM: This study aimed to generate data for the S1 and S2 alar pedicle and body and the alar orientations for both dysmorphic and normal sacra. MATERIALS AND METHODS: The study comprised two groups: Group N consisted of 53 normal sacra and Group D included 10 dysmorphic sacra. Various features such as alar pedicle circumference; anterior, middle, and posterior axis of the sacral ala; sacral body height and width; and sagittal thickness were measured. RESULTS: In group N, the median anterior axis of the alae was observed to be 30° on the right and 25° on the left, the median midline axis was found to be 20° on the right and 15° on the left, and the median posterior alar axis was -15° on the right and -20° on the left. The true S1 and S2 alar pedicle circumferences were observed to be significantly smaller in group D, which demonstrated a shorter S1 alar pedicle mean circumference, significantly narrower S1 body mean width, and considerably tapered sagittal thickness. CONCLUSION: Our analysis indicated that dysmorphic sacra have a lower sagittal thickness and width of bodies and smaller alar pedicles, which explains the difficulties in their percutaneous fixation.

RESUMEN

BACKGROUND: Percutaneous iliosacral screw fixation of the posterior pelvic ring is a demanding procedure with high exposure to radiation. The conventional technique includes the use of three classical projections with the C-arm: inlet, outlet, and true lateral views. A projection in the axis of the upper sacral alar pedicles with a 30° cephalad and 30° ventral oblique view would help in obtaining a more accurate visualization of the safe corridor. Two subcutaneously placed K-wires, one placed horizontally and one vertically, may facilitate the starting point and aim changes by offering the surgeon an option for exactly matching the position of the sacrum with the image. The purpose of this study was to detect if the radiation application could be decreased by our new methodology. METHODS: Seventeen patients with pelvic posterior ring disruptions, in which percutaneous iliosacral screw placement was indicated, were included in the study. Group 1 comprised 7 patients in whom conventional projections and technique were used. Group 2 comprised 10 patients in whom 30°­30° projection and sacral mapping technique via two subcutaneous K-wires were applied. Radiation exposure time, total fluoroscopic shot count, fluoroscopic shot count needed for only guide wire and screw placement, radiation dose, and complications were compared between the two groups. RESULTS: The median number of fluoroscopic images for guide and screw placement was 132 (56­220) and 29.5 (19­83) in Groups 1 and 2, respectively, and the difference was statistically significant (p < 0.001). The median total fluoroscopic radiation time was 138 (68­234) and 52 (28­77) s in Groups 1 and 2, respectively, and the difference was significant (p < 0.001). Group 1 had a significantly higher median radiation dose than Group 2 [3020 (1502­6032) vs. 1192 (426­2359); (p = 0.001)]. CONCLUSIONS: Iliosacral screw placement with the help of sacral mapping and a fourth view, "30°­30°", helps the surgeon to markedly reduce the fluoroscopic shots, radiation time and dose during guide wire and screw placement. LEVEL OF EVIDENCE: Therapeutic, Level II.
