Acromioclavicular Joint Lesions in Adolescents-A Systematic Review and Treatment Guidelines.

True acromioclavicular joint (ACJ) injuries are rare in children and adolescents due to the strength of ligaments in this age group. However, a standardized management guideline for these injuries is currently lacking in the literature. This systematic review aims to provide an organized overview of associated injuries and propose a management algorithm for pediatric ACJ injuries. Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a systematic review was conducted. Two independent observers searched PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and Scopus databases for ACJ injuries in children and adolescents. The extracted data were analyzed (due to the limited number of publications and inhomogeneity of data, no formal statistical analysis was conducted), and cases were categorized based on injury frequency and pattern, leading to the formulation of a treatment algorithm. The risk of bias was assessed using the Joanna Briggs Institute (JBI) critical appraisal checklist. A total of 77 articles were identified, and 16 articles (4 case series and 12 case reports) met the inclusion criteria. This study included 37 cases in 36 patients (32 males, 4 females) with a mean age of 13 years (9-17 years). Six injury categories were described. Surgical management was performed in 27 ACJ injuries (25 open, 2 arthroscopic). Various surgical implants were used including K wires, polydioxanone sutures (PDS), screws, hook plates, suture anchors, and suture button devices. Most cases achieved good to excellent outcomes, except for one case of voluntary atraumatic dislocation of the ACJ. This systematic review provides the first comprehensive analysis of ACJ injury management in adolescents with open physis. It categorizes injury patterns and presents a treatment algorithm to enhance the understanding of these injuries. The review's findings contribute valuable insights for clinicians dealing with pediatric ACJ injuries.

Long-Term Evaluation of Ulnar Nerve Function in Patients with Distal Humerus Fractures Treated with Open Reduction and Internal Fixation: A Nerve Conduction Study.

OBJECTIVES: To investigate the long-term evaluation with electromyography of ulnar nerve function in patients with distal humerus fractures (DHFs) treated with open reduction and internal fixation. DESIGN: Retrospective cohort study. SETTING: Level 1 trauma center. PATIENTS: Fifty-two patients (20 men and 32 women) with DHFs. INTERVENTIONS: All patients underwent open reduction and internal fixation between 2002 and 2017 with a minimum five years' follow-up. MAIN OUTCOME MEASUREMENTS: The nerve conduction test was done for evaluation ulnar nerve function. Secondary outcomes were modified McGowan grading system for symptoms of ulnar neuropathy. RESULTS: The mean follow-up time was 112.7 ± 39 months after surgery. 28.8% (15) of the patients scored in Grade I, 30 (57.6%) in Grade II, and 7 (13.6%) in Grade III on the affected side according to McGowan grading scale. According to EMG results, 40.1% (21/52) of patients had abnormal results. There was significant difference between fracture and unaffected side regarding ulnar nerve motor wrist CMAP amplitude, motor below elbow CMAP amplitude, above elbow CMAP amplitude, above elbow MNCV, and sensory wrist amplitude. Ulnar nerve motor wrist-ADM latency (p = 0.01; r = 0.446) and ulnar nerve sensory conduction velocity (p < 0.001, r = -0.504) were significant correlation with McGowan grading scale. CONCLUSION: There were significant difference ulnar nerve motor amplitude and sensory wrist amplitude between fracture and unaffected side. A mean decrease in sensory amplitude of fracture elbow was found 25% compared to the unaffected side in our result. LEVEL OF EVIDENCE: Diagnostic Level III.

Arthroscopic superior capsular reconstruction versus reverse shoulder arthroplasty in patients with massive irreparable rotator cuff tears: A comparative clinical study.

OBJECTIVE: This study aimed to compare the clinical and functional outcomes of reverse shoulder arthroplasty versus arthroscopic supe- rior capsular reconstruction in the treatment of patients with massive irreparable rotator cuff tears and Hamada grade 1-2 glenohumeral arthritis. METHODS: It is a retrospective case-control study comparing the prospective results of 2 different treatment methods. This retrospective comparison of groups was conducted between May 2016 and May 2020. The study included 40 people with massive irreparable rotator cuff tear and Hamada grade 1-2 arthropathy who had arthroscopic superior capsular reconstruction with tensor fascia latae autograft or reverse shoulder arthroplasty surgery. Patients were divided into 2 groups according to treatment. Clinical outcome measures included shoulder range of motion, pain, and functional scores (Constant-Murley, American Shoulder and Elbow Surgeons). RESULTS: The mean age was 61.85 ± 7.56 and 71.10 ± 6.42 years, respectively, for group I [superior capsular reconstruction (n=20)] and group II [superior capsular reconstruction (n=20)]. The mean follow-up was 22.30 ± 8.4 and 32.50 ± 8.11 months, respectively. In the postoperative data, flexion degrees and Constant scores were significantly higher in the superior capsular reconstruction group (P=.007, P = .043). No significant difference was found between the 2 groups in all parameters (P > .05) except abduction. The increase in abduction value in the reverse shoulder arthroplasty group was significantly higher than in the superior capsular reconstruction group (P = .003). In addition, postoperative data in all parameters in both groups showed significant changes compared to preoperatively. CONCLUSION: This study has shown that superior capsular reconstruction with tensor fascia latae autograft can provide clinical and func- tional improvement similar to the reverse shoulder arthroplasty procedure in treating massive irreparable rotator cuff tears with Hamada grade 1-2 arthropathy. LEVEL OF EVIDENCE: Level III, Therapeutic Study.

Intra- and inter-observer reliability of Dias-Tachdjian classification in pediatric ankle fractures: do clinical experience and expertise matter?

The Dias-Tachdjian classification is the most commonly used system for the classification of pediatric ankle fractures, but its inter- and intra-observer reliability has not been studied in detail. Also, the impact of the clinician's experience and expertise on the reliability of this system is unknown. This study aimed: (1) to determine the intra- and inter-observer reliability of the Dias-Tachdjian classification and (2) to investigate the effect of the clinician's experience and expertise on the reliability of this system. Anteroposterior and lateral ankle radiographs of 56 children (34 male, 22 female) with ankle fractures, aged between 3 and 14 years, with open growth cartilages, were retrospectively identified and included in the study. Each patient radiograph was examined by 10 observers from two different specialties with different levels of clinical experience (two orthopedic surgeons with interest in pediatric orthopedics, three orthopedic surgeons with no interest in pediatric orthopedics, three orthopedic residents, and two radiology specialists) from two different specialties (orthopedics and radiology). All observers were then asked to classify pediatric ankle fractures at 6-week intervals per the Dias-Tachdjian classification system. Overall, intra-observer reliability as substantial to very good (κ = 0.77-0.95, P < 0.01), but inter-observer reliability as fair for both assessments (κ = 0.21, P < 0.01 and κ = 0.20, P < 0.01 for the first and second occasions, respectively). Inter-observer reliability among pediatric orthopedic surgeons as very good (κ = 0.90, 95% CI = 0.86-0.94, P < 0.01 and κ = 0.82, 95% CI = 0.71-0.93, P < 0.01 for the first and second occasions, respectively). Orthopedic surgeons with no special interest in pediatric orthopedics demonstrated substantial agreement in the first occasion (κ = 0.63, 95% CI = 0.53-0.72, P < 0.01) but moderate in the second one. Orthopedic residents exhibited moderate levels of agreement in each assessment period (κ = 0.58, 95% CI = 0.47-0.68, P < 0.01 and κ = 0.44, 95% CI = 0.37-0.51, P < 0.01 for the first and second occasion, respectively). Considering that the specialists dealing with pediatric orthopedics show very good consistency for Dias-Tachdjian classification, both within and between observers, consistency in the identification of the ankle fracture models increases as the interest in the field of pediatric orthopedics intensifies.

Multidirectional instability of the shoulder: surgical techniques and clinical outcome.

Multidirectional instability of the shoulder has a complex pathoanatomy. It is characterized by a redundant glenohumeral capsule and increased joint volume. Subtle clinical presentation, unclear trauma history and multifactorial etiology poseses a great challenge for orthopedic surgeons in terms of diagnosis. Generally accepted therapeutic approach is conservative and the majority of patients achieve good results with rehabilitation. In patients who are symptomatic despite appropriate rehabilitation, surgical intervention may be considered. Good results have been obtained with open inferior capsular surgery, which has historically been performed in these patients. In recent years, advanced arthroscopic techniques have taken place in this field, and similar results compared to open surgery have been obtained with the less-invasive arthroscopic capsular plication procedure.

IS VOLAR PLATING IN DISTAL RADIUS FRACTURES SAFE REGARDING PRONATOR QUADRATUS?

Objective: This study aimed to investigate whether isokinetic strength decrease significantly after using volar plating for distal radius fractures and evaluate the pronator quadratus muscle regarding atrophy. Methods: This study took place between 2011 and 2015 and included 18 distal radius fracture patients (group 1) who were treated via volar plating at least one year prior and 14 healthy controls (group 2). All participants were tested isokinetically. Grip strength, radiological evaluation, wrist range of motion, disabilities of the arm, shoulder, and hand and visual analog scale scores were assessed for clinical and functional outcomes. Ultrasonography evaluated the pronator quadratus muscle thicknesses. Results: The peak supination torque (PT) and supination work per repetition (WPT) strength values significantly decreased (p:0.039, p:0.025, respectively). Although we determined an 11% pronation PT deficit and a 19% pronation WPT deficit, neither were significant. In group 1, the pronator quadratus muscle thickness decreased 5.9% ± 13.3 in the radial area and 9.7% ± 10.5 in the interosseous area according with ultrasonography; these results were not statistically significant compared to group 2. All clinical and functional outcomes were not statistically significant between the groups. Conclusion: The use of volar plating after distal radius fractures is a safe method regarding isokinetic strength and pronator quadratus muscle atrophy. Level of evidence III; Retrospective case-control study .

Objetivo: Este estudo teve como objetivo investigar se as forças isocinéticas diminuem significativamente após o uso de placa volar para tratamento de fraturas do rádio distal e avaliar o músculo pronador quadrado quanto à atrofia. Métodos: Este estudo realizado entre 2011 e 2015 incluiu 18 pacientes com fratura do rádio distal (grupo 1) que tenham sido tratadas com placa volar pelo menos um ano antes e 14 pessoas saudáveis como controle (grupo 2). Todos os participantes foram testados isocineticamente. Força de preensão, avaliação radiológica, amplitude de movimento do punho, deficiências do braço, ombro e mão e escores da escala visual analógica foram avaliados clinica e funcionalmente. A ultrassonografia avaliou a espessura do músculo pronador quadrado. Resultados: A força máxima do torque de supinação (TM) e do trabalho por repetição (ER) de supinação diminuíram significativamente (p: 0,039, p: 0,025, respectivamente). Embora tenhamos determinado um déficit de TM de pronação de 11% e um déficit de ER de pronação de 19%, nenhum dos dois foi significativo. No grupo 1, a espessura do músculo pronador quadrado diminuiu 5,9% ± 13,3 na área radial e 9,7% ± 10,5 na área interóssea, segundo ultrassonografia; estes resultados não foram estatisticamente significativos em comparação com o grupo 2. Nenhum resultados clínico ou funcional foi estatisticamente significativo entre os grupos. Conclusão: O uso de placa volar após fraturas do rádio distal é um método seguro em relação à força isocinética e atrofia do músculo pronador quadrado. Nível de evidência III; estudo retrospectivo de caso-controle .

Reasons for resident resignations from Orthopedic Residency Programs in Turkey: A cross-sectional survey from residents' perspectives.

OBJECTIVE: The aim of this study was to analyse the factors that led to resignations from Orthopaedics and Traumatology Residency pro- grammes in Turkey, and to determine the overall rate of resignation among residents from Orthopaedics and Traumatology programmes. 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 ques- tionnare 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%). CONCLUSION: The results of this survey have shown us, with an overall resignation rate of 8.2% as per the total quotas for OT residency from 2013 to 2020, that resignation from OT residency represents an important problem in Turkey. Workload and excessive hours of work were the most common reasons for resignation from orthopaedic residency programmes. Furthermore, extra work that diverted residents from their actual job responsibilities, as well as academic and educational concerns, were the main factors leading to transfer to another OT residency programme.

Use of Recombinant Factor VIIa for Bleeding Control in Treatment of Acute Extremity Compartment Syndrome Secondary to Primary Myelofibrosis: A Case Report.

CASE: A 40-year-old man was admitted to our emergency department with a painful and swollen calf. There was no history of significant trauma, and the physical examination revealed a pulseless, swollen left lower leg. Clinical history revealed a diagnosis of primary myelofibrosis, and magnetic resonance imaging showed a rupture of the gastrocnemius medial head. The diagnosis of spontaneous acute extremity compartment syndrome (AECS) secondary to myelofibrosis was established. An open fasciotomy procedure was performed, and recombinant factor VIIa treatment was applied to control bleeding. Postoperatively, fasciotomy wounds were closed with skin grafts. CONCLUSION: AECS may develop in patients with bleeding disorders, and recombinant factor VII may help control bleeding.

Instant messaging application usage for clinical consultation among orthopedic surgery residents in Turkey: A survey study.

OBJECTIVE: This study aimed to determine the characteristics of instant messaging application (IMA) usage for clinical consultation among orthopedic residents in Turkey and to explore their experiences and opinions concerning potential legal problems. METHODS: A questionnaire titled "Instant messaging for consultation among orthopedic surgeons" consisting of 21 questions was applied to orthopedic surgery residents, and the results were analyzed. The questions were designed to obtain information on 4 categories: 1) demographics and professional experience, 2) attitudes on the use of cellular phones, 3) IMA usage for clinical consultation purposes, and 4) problems and comments on smartphone application usage for clinical consultation purposes. The participants who had no experience with a smartphone or IMA usage were excluded at the final analysis. RESULTS: A total of 860 orthopedic residents (849 males [98.7%]; mean age=28.6 years; age range=22-44 years) participated in the survey (participation rate: 97.3%). The distribution of residency years was as follows: 1st year, 27%; 2nd year, 21.4%; 3rd year, 18.4%; 4th year, 17.4%; and 5th year, 49.9%. The most frequently used IMAs were WhatsApp (99.3%), Facebook Messenger (14.8%), Viber (8%), and Tango (1.3%). The rate of IMA usage for consultation was 95.3%. The most common reasons to prefer IMAs for consultation were being "fast" and "easy," but only 26.3% of the residents reported that they prefer the use of IMAs because they find them "reliable." Moreover, 41.7% of the respondents reported that they had an experience of misdiagnosis owing to the use of IMAs; 81.2% of the participants used the personal information of the patients during the consultation; 57.6% of the respondents considered that legal problems may arise because of the use of IMAs during the consultation; and 51.4% believed that an electronic platform, solely for consultation purposes, is required. CONCLUSION: This survey has shown that it is necessary to make some legal regulations regarding the use of IMAs for consultation purposes and to develop applications only for medical consultation purposes. Most of the trainees make decisions using IMAs without a proper examination, putting the patients at the risk of misdiagnosis. Moreover, the confidentiality of the patient's personal information appears to be in danger when IMAs are used. LEVEL OF EVIDENCE: Level IV, Diagnostic Study.

Correlations between radiographic spinopelvic parameters and health-related quality of life: A prospective evaluation of 37 patients with facioscapulohumeral muscular dystrophy.

OBJECTIVE: The purpose of this study was to evaluate the relationship between spinopelvic parameters and health-related quality of life. METHODS: Patients with Facioscapulohumeral muscular dystrophy (FSHD) were asked to volunteer to participate in this study from April 2018 to December 2019. Patient data, including age, sex, body mass index (BMI), and duration of the diagnosis of FSHD were obtained. Short Form (SF-36) questionnaire was completed for all patients. All patients underwent lateral radiography of the whole spine. The radiographic parameters examined were pelvic tilt (PT), pelvic incidence (PI), sacral slope (SS), lumbar lordosis (LL), cervical lordosis (CL), T1 spinopelvic inclination (T1 SPI), thoracic kyphosis (TK), Pelvic incidence- lumbar lordosis (PI-LL) and sagittal vertical axis (SVA). RESULTS: Thirty-seven patients (16 females and 21 males) were included in the study, with a mean age of 39.1 years. The mean duration of diagnosis was 13.5 ± 11.4 years and mean BMI was 24.2 kg/m2. Physical composite score (PCS) was 38.7 and mental composite score (MCS) 60.8 detected. Radiographic analyses included the following: the mean PT was 9.1°, PI 52.1°, SS 43.5°, LL 67.9°, CL 9.8°, T1 SPI -2.5°, TK 23.1°, SVA 37.6 mm. PI-LL was -13.1°. We identified 31 patients with match (left) PI-LL and six patients with mismatch (right) PI-LL. CONCLUSION: Hyperlordosis inlumbar spine, hypolordosis in cervical spine and negative sagittal balance were the most common spinal misalignments in patients with FSHD. These patients have lower composite PCS than composite MCS. There was a significantly negative correlation between LL, PI-LL and PCS. LEVEL OF EVIDENCE: Level IV Cross-sectional study.

Isokinetic Strength Comparison of Tuberosity Fractures of the Proximal Fifth Metatarsal Treated With Elastic Bandage vs Cast.

BACKGROUND: The aim of this study was to compare the strength of injured and healthy ankle muscle as well as functional and clinical outcomes between patients with proximal fifth metatarsal tuberosity fractures who received elastic bandage treatment and those who received cast immobilization. METHODS: Sixty-five patients who presented to our clinic between February 2018 and April 2019 were randomly divided into 2 groups: 33 received elastic bandages (group 1) and 32 received cast immobilization (group 2). All patients were scheduled for follow-up appointments at our clinic after 2, 4, 8, 12, and 24 weeks. Visual analog scale-foot and ankle (VAS-FA) score, time missed from work, and using assistive devices were recorded as clinical outcomes. Both ankle plantarflexion-dorsiflexion and inversion-eversion muscle strengths (peak torque) were measured using an isokinetic dynamometer for each group and were compared with those of the healthy extremities. RESULTS: The mean missed work was 11.3 days in group 1 and 27.6 days in group 2. Groups 1 and 2 used assistive devices for a mean of 6.7 and 16.2 days, respectively (P = .001). Group 1 had a significantly higher VAS-FA score at the 2nd, 4th, and 8th week of follow-up compared with group 2, and no significant differences were observed at the time of injury and at the 12th and 24th weeks. The muscle strength deficits in group 1 were present at the 4th week, whereas those in the cast immobilization group were determined at the 4th and 8th weeks in all muscles. During the 12th and 24th week of follow-up, no significantly differences in both extremities were observed between the groups. CONCLUSION: Elastic bandage treatment was better than cast immobilization in terms of preserving ankle muscle strength, clinical outcomes, and functional scores regardless of the degree of fracture displacement. Moreover, the present study emphasized that cast immobilization offered no advantages in this fracture treatment. LEVEL OF EVIDENCE: Level I, prognostic randomized controlled trial.

Critical Limit of Lower-Extremity Lengthening in Total Hip Arthroplasty: An Intraoperative Neuromonitorization Study.

BACKGROUND: The effect of limb lengthening on neural structures was assessed with use of intraoperative neuromonitoring (IONM) during primary total hip arthroplasty (THA). The relationship between the critical limit of lengthening and anthropometric measurements was evaluated. METHODS: Motor evoked potentials (MEPs) from the deep peroneal nerve (tibialis anterior muscle), tibial nerve (gastrocnemius muscle), and femoral nerve (quadriceps muscle), as well as somatosensory evoked potentials (SEPs) from the posterior tibial nerve, were recorded in 16 patients undergoing THA. Height, weight, the distance between the anterior superior iliac spine and the medial malleolus (ASIS-MM distance), and the total femoral length were measured preoperatively. Lower-extremity traction was performed after resection of the femoral head, and the amount of extremity lengthening was measured with use of an image intensifier. A maximum of 50% reduction in any one of the SEP or MEP amplitudes or a 10% increase in the SEP latency were considered to be indicative of the critical limit of lengthening. RESULTS: Initial IONM changes (indicating the safe limit of lengthening) and maximum allowed IONM changes (indicating the critical limit of lengthening) were reached in the deep peroneal nerve in all cases. The mean safe limit of lengthening (and standard deviation) was 14.9 ± 6.2 mm (3% relative to femoral length and 1.7% relative to ASIS-MM distance), whereas the critical limit of lengthening was exceeded at a mean of 22.4 ± 5.6 mm (5% relative to femoral length and 2.6% relative to ASIS-MM distance). When the critical limit was reached in the deep peroneal nerve, the mean decrease in MEP amplitudes was 27% (95% confidence interval [CI], 22.1% to 32.7%) for the tibial nerve and 12% (95% CI, 6.9% to 18.1%) for the femoral nerve. There was a positive correlation between critical lengthening and femoral length (r = 0.782; p < 0.001), ASIS-MM distance (r = 0.811; p < 0.001), and height (r = 0.835; p = 0.001). No correlation existed between the critical lengthening amount and the decrease in amplitude in the tibial and femoral nerves. CONCLUSIONS: The critical limit of nerve lengthening was directly correlated with anthropometric measurements. Nerve lengthening of 5% relative to femoral length and of 2.6% relative to ASIS-MM distance was found to be critical; however, these limits depended on the predetermined threshold values for IONM.

Prevalence of asymptomatic femoroacetabular impingement in Turkey; cross sectional study.

OBJECTIVES: Femoroacetabular impingement (FAI) is one of the causes of hip pain in young-adult patients. The purpose of our study is to determine the prevalence of radiological FAI findings in asymptomatic population in Turkey. METHODS: Trauma patients aged 18-65 years who applied to the emergency service between September 2015 and September 2016 were retrospectively evaluated for this study. After a preliminary study and power analysis, 2152 hips of the 1076 previously asymptomatic patients were evaluated radiologically with pelvis antero-posterior and frog-leg radiographs. On radiographs of these patients; alpha angle, lateral central edge angle (LCEA), Tönnis angle (TA) and collodiaphyseal angle were measured. Alpha angle values higher than 55° were noted as cam type FAI. TA values lower than 0° or LCEA values higher than 39° were noted as pincer type FAI. LCEA values lower than 25° or TA values higher than 10° were noted as acetabular dysplasia. RESULTS: Mean age of 1076 patients (602 female, 474 male) was 42.1 ±â€¯15.6 years. The assessment showed that 15.9% of the patients had cam type, 10.6% had pincer type, 3.1% had combined type FAI and 9.3% had findings of acetabular dysplasia. The prevalence of asymptomatic FAI is significantly more in males (46%) in comparison to females (17%) in Turkey. CONCLUSION: Even though FAI is considered to be a pathology associated with hip osteoarthritis; it is very common in asymptomatic population. In this respect, our study showed that prevalence of radiological FAI findings in asymptomatic adult population was 29.6% in Turkey.
