RESUMO

OBJECTIVE: The reconstruction of complex soft tissue defects with exposure of bones and tendons represents an increasing challenge in wound care, especially in large extremity wounds. The aim of this study was to detect the clinical efficacy of combined use of negative pressure wound therapy (NPWT), artificial dermis (ADM), platelet-rich plasma (PRP) and split-thickness skin grafting (STSG) in the reconstruction of large traumatic extremity skin defects. METHOD: In this study, eight cases were treated with combined therapies for repairing complex extremity wounds and the results were reviewed retrospectively. After surgical debridement, all wounds received ADM, PRP and delayed STSG, which were all aided with NPWT. RESULTS: The patients consisted of five males and three females, with a mean age of 44 years. A total of six lower extremity wounds were located at the foot/ankle, with exposed tendon in five, bone exposure in three and both in two. Of the group, two patients had exposed tendon on arm/hand wounds. The size of wounds and ADM averaged 126cm2 and 42.3cm2, respectively. ADM was used to cover the exposed bone or tendon, the granulation and muscular tissue were covered with vacuum sealing drainage (VSD) directly, for NPWT. The survival rate of ADM averaged 98.9%. The average time for survival of ADM was 12.8 days and the mean uptake of autologous skin graft was 93.5%. Only one patient received repeated skin grafts. All patients achieved successful healing and reported no complications. The mean length of hospital stay was 36.1 days. CONCLUSION: Our study revealed that ADM in conjunction with NPWT, PRP and STSG could be used for repairing large traumatic extremity wounds. Wound closure was achieved without flaps, the aesthetic and functional outcomes were acceptable, and only one patient developed a 35% loss of skin graft.

RESUMO

Hand-arm vibration injury is a well-known occupational disorder that affects many workers globally. The diagnosis is based mainly on quantitative psychophysical tests and medical history. Typical manifestations of hand-arm vibration injury entail episodes of finger blanching, Raynaud's phenomenon (RP) and sensorineural symptoms from affected nerve fibres and mechanoreceptors in the skin. Differences in serum levels of 17 different biomarkers between 92 patients with hand-arm vibration injury and 51 controls were analysed. Patients with hand-arm vibration injury entailing RP and sensorineural manifestations showed elevated levels of biomarkers associated with endothelial injury or dysfunction, inflammation, vaso- or neuroprotective compensatory, or apoptotic mechanisms: intercellular adhesion molecule-1 (ICAM-1), monocyte chemoattractant protein-1 (MCP-1); thrombomodulin (TM), heat shock protein 27 (HSP27); von Willebrand factor, calcitonin gene-related peptide (CGRP) and caspase-3. This study adds important knowledge on pathophysiological mechanisms that can contribute to the implementation of a more objective method for diagnosis of hand-arm vibration injury.

RESUMO

DESIGN: Clinimetric evaluation study. INTRODUCTION: The Chinese Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire has necessitated the development of a revised version to the specific needs of individuals with upper extremity injuries with the progress of times and lifestyle changes. PURPOSE OF THE STUDY: This research aimed to evaluate the reliability and validity of Modified Chinese Disability of Arm, Shoulder and Hand (MC-DASH) questionnaire in individuals with upper extremity injuries. METHODS: One hundred and one individuals with upper extremity injuries (UEI) were recruited. The function of upper extremity was measured using the electronic version of MC-DASH, and compared against the Chinese Disability of Arm, Shoulder and Hand. The MC-DASH was reassessed within three days in all individuals. We investigated the internal consistency, test-retest reliability, content validity, criterion validity, and construct validity of MC-DASH. RESULTS: The internal consistency was deemed sufficient, as indicated by a Cronbach's alpha of 0.986 and an intraclass correlation coefficient of 0.957. Moreover, the mean total scores of MC-DASH on the first-test and retest were 37.86 and 38.19, respectively (ICC: 0.957, 95 %CI: 0.937-0.971, p < 0.001). Furthermore, the MC-DASH version exhibited satisfactory content validity evidenced by its strong correlation (R= 0.903, p < 0.001) with the Chinese DASH. Three major influencing factors were identified from 37 items. The cumulative variance contribution rate of the MC-DASH questionnaire was 75.76 %, confirming its construct validity. CONCLUSION: The Modified Chinese Disability of Arm, Shoulder and Hand questionnaire has been shown to be a valid, reliable, and practical tool for use in patients with upper extremity injuries.

RESUMO

CASE: A 23-year-old man presented with a right upper limb injury after a 10-m fall. Initial evaluation demonstrated a terrible triad elbow injury associated with a trans-scaphoid perilunate dislocation. Elbow stabilization with radial head replacement and carpal fixation was performed. Radiographs on postoperative day 7 demonstrated an ipsilateral Essex-Lopresti injury, which had been initially missed, and revision surgery was performed to reconstruct the interosseous membrane. CONCLUSION: Surgeons should maintain a high degree of suspicion for an ipsilateral Essex-Lopresti injury in patients with a terrible triad elbow fracture-dislocation in combination with a trans-scaphoid perilunate dislocation. Both preoperative imaging, including the contralateral side, and intraoperative evaluation are recommended to rule out longitudinal instability of the forearm in the setting of combined wrist and elbow fracture-dislocations.

RESUMO

BACKGROUND: Heterotopic ossification (HO) is a common complication after elbow fracture surgery and can lead to severe upper extremity disability. The radiographic localization of postoperative HO has been reported previously. However, there is no literature examining the distribution of postoperative HO at the three-dimensional (3D) level. This study aimed to investigate 1) the distribution characteristics of postoperative HO and 2) the possible risk factors affecting the severity of postoperative HO at a 3D level. METHODS: A retrospective review was conducted of patients who presented to our institution with HO secondary to elbow fracture between 13 January 2020 and 16 February 2023. Computed tomography scans of 56 elbows before elbow release surgery were reconstructed in 3D. HO was identified using density thresholds combined with manual identification and segmentation. The elbow joint and HO were divided into six regions according to three planes: the transepicondylar plane, the lateral ridge of the trochlear plane, and the radiocapitellar joint and coronoid facet plane. The differences in the volume of regional HO associated with different initial injuries were analyzed. RESULTS: Postoperative HO was predominantly present in the medial aspect of the capsule in 52 patients (93%), in the lateral aspect of the capsule in 45 patients (80%), in the medial supracondylar in 32 patients (57%), and in the lateral supracondylar, radial head, and ulnar region in the same number of 28 patients (50%). The median and interquartile range volume of total postoperative HO was 1683 (777-4894) mm3. The median and interquartile range volume of regional postoperative HO were: 584 (121-1454) mm3 at medial aspect of capsule, 207 (5-568) mm3 at lateral aspect of capsule, 25 (0-449) mm3 at medial supracondylar, 1 (0-288) at lateral supracondylar, 2 (0-478) at proximal radius and 7 (0-203) mm3 at the proximal ulna. In the subgroups with Injury Severity Score > or = 16, Gustilo-Anderson II, normal uric acid levels, elevated alkaline phosphatase, and body mass index > or = 24, the median HO volume exceeds that of the respective control groups. CONCLUSION: The medial aspect of the capsule was the area with the highest frequency and median volume of postoperative HO among all initial elbow injury types. Patients with higher Gustilo-Anderson grade, Injury Severity Score, alkaline phosphatase or Body Mass Index had higher median volume of postoperative HO.

RESUMO

BACKGROUND: Upper extremity (UE) trauma requiring operative care increases during the summer and fall months, which the authors colloquially refer to as "trauma season." METHODS: CPT databases were queried for codes related to acute UE trauma at a single level-1 trauma center. Monthly CPT code volume was tabulated for 120 consecutive months and average monthly volume was calculated. Raw data were plotted as a time series and transformed as a ratio to the moving average. Autocorrelation was applied to the transformed data set to detect yearly periodicity. Multivariable modeling quantified the proportion of volume variability attributable to yearly periodicity. Subanalysis assessed presence and strength of periodicity in four age groups. RESULTS: A total of 11,084 CPT codes were included. Monthly trauma-related CPT volume was highest in July through October and lowest in December through February. Time-series analysis revealed yearly oscillation in addition to a growth trend. Autocorrelation revealed statistically significant positive and negative peaks at a lag of 12 and 6 months, respectively, confirming yearly periodicity. Multivariable modeling revealed R 2 attributable to periodicity of 0.53 ( P < 0.01). Periodicity was strongest in younger populations and weaker in older populations. R 2 was 0.44 for ages 0 to 17, 0.35 for ages 18 to 44, 0.26 for ages 45 to 64, and 0.11 for ages 65 and older. CONCLUSIONS: Operative UE trauma volumes peak in the summer and early fall and reach a winter nadir. Periodicity accounts for 53% of trauma volume variability. The authors' findings have implications for allocation of operative block time and personnel and expectation management over the course of the year.

RESUMO

Although pitching-related injuries in the overhead athlete have been studied extensively, injuries associated with windmill pitching are not as clearly elucidated. Windmill pitching produces high forces and torques in the upper extremity, and studies have shown it creates similar shoulder and elbow joint loads to those reported in baseball pitchers. Studies have shown that the windmill pitching motion generates high levels of biceps activation with an eccentric load, placing the biceps at increased risk for overuse injuries. Although the American Orthopaedic Society for Sports Medicine published prevention guidelines including recommendations for maximum pitch counts in softball, these recommendations have not been adopted by most United States softball governing bodies. The repetitive windmill motion in conjunction with high pitch count demands in competitive softball creates notable challenges for the sports medicine physician. As with overhead throwing athletes, identifying and preventing overuse is crucial in preventing injuries in the windmill pitcher, and prevention and rehabilitation should focus on optimizing mechanics and kinematics, core, hip, and lower body strength, and recognition of muscle fatigue. With more than two million fastpitch softball participants in the United States, it is essential to better understand the etiology, evaluation, and prevention of injuries in the windmill pitching athlete.

RESUMO

BACKGROUND: Upper-extremity fractures (UEFs) account for a large proportion of bone fractures and are costly to both health and the economy. The fracture burden in the Middle East and North Africa (MENA) is influenced by the region's diverse cultural, economic, and political status. This study examined UEF epidemiology and causes across the MENA region and within the 21 MENA countries as categorized by the Global Burden of Disease (GBD) data set. METHODS: On the basis of GBD data, this study evaluated the epidemiology of UEFs from 1990 to 2019. The causes of injuries, incidence, number of years of healthy life lost due to disability (YLD), and their association with the Socio-demographic Index (SDI) were obtained and calculated for males and females in all age groups. RESULTS: From 1990 to 2019, the age-standardized incidence rate (ASIR) of UEFs in the MENA region increased by 2.33%, to 1,086.39 per 100,000 people, and the YLD rate increased 15.69%, to 9.17 per 100,000, opposing the global decreasing trends. Fractures of the radius and/or ulna had the highest ASIR (505.32 per 100,000) of all UEF types in 2019. The clavicle, scapula, and humerus had the highest increasing trend among the fracture sites. In 2019, Saudi Arabia had the highest ASIR of UEFs (2,296.93 per 100,000). Afghanistan had the highest age-standardized YLD rate due to UEFs (19.6 per 100,000) in 2019, with Syria (153.32%) and Iran (37.04%) experiencing the greatest increase and decrease, respectively, from 1990 to 2019. Falling was the leading cause of UEFs, accounting for 45.05% of incidence and 41.19% of YLD overall. CONCLUSIONS: Contrary to global trends, UEFs increased in the MENA region during the study period. Countries with higher fracture incidence and YLD should consider preventive and rehabilitation strategies.

RESUMO

BACKGROUND: It has been suggested that hypertrophy of the radial tuberosity may result in impingement leading to either a lesion of the distal biceps tendon or rotational impairment. Two previous studies on hypertrophy of the radial tuberosity had contradictory results and did not examine the distance between the radius and ulna: the radioulnar window. Therefore, this comparative cohort study aimed to investigate the radioulnar window in healthy subjects and compare it with that in subjects with either nontraumatic-onset rotational impairment of the forearm or nontraumatic-onset distal biceps tendon ruptures with rotational impairment of the forearm by use of dynamic 3-dimensional computed tomography measurements to attain a comprehensive understanding of the underlying etiology of distal biceps tendon ruptures. We hypothesized that a smaller radioulnar window would increase the risk of having a nontraumatic-onset distal biceps tendon rupture and/or rotational impairment compared with healthy individuals. METHODS: This study measured the distance between the radius and ulna at the level of the radial tuberosity using entire-forearm computed tomography scans of 15 patients at the Amphia Hospital between 2019 and 2022. Measurements of healthy subjects were compared with those of subjects who had nontraumatic-onset rotational impairment of the forearm and subjects who had a nontraumatic-onset distal biceps tendon rupture with rotational impairment of the forearm. The Wilcoxon signed rank test was used for individual comparisons, and the Mann-Whitney U test was used for group comparisons. RESULTS: A significant difference was found between the radioulnar window in the forearms of the subjects with a distal biceps tendon rupture (mean, 1.6 mm; standard deviation 0.2 mm) and the radioulnar window in the forearms of the healthy subjects (mean, 4.8 mm; standard deviation, 1.4 mm; P = .018). A trend toward smaller radioulnar windows in the rotational impairment groups was also observed, although it was not significant (P > .05). CONCLUSIONS: The radioulnar window in the forearms of the subjects with a distal biceps tendon rupture with rotational impairment was significantly smaller than that in the forearms of the healthy subjects. Therefore, patients with a smaller radioulnar window have a higher risk of rupturing the distal biceps tendon. Nontraumatic-onset rotational impairment of the forearm may also be caused by a similar mechanism. Future studies are needed to further evaluate these findings.

RESUMO

There has been an epidemic increase in injuries to the elbow in our youth sports over the past 15 years. Initially, career-ending elbow injuries occurred almost exclusively in the professional population. The landmark procedure developed by Dr. Frank Jobe, colloquially termed "Tommy John surgery" after the initial player in whom he performed the surgical procedure, allowed roughly two-thirds of professional athletes to return to play at or near the same level. As the surgical procedure became more widespread, modifications of the technique by Jobe and many other contributors raised the return-to-play level to 85%-94% of players regaining the ability to return to sport at the preinjury level. Almost simultaneously, the emphasis on velocity in the professional ranks led to an unintentional increase in stress on the throwing elbow. This was magnified in our athletes by the advent of year-round sports, as well as the formation of "showcase" events to demonstrate skills and measure velocity. This, unfortunately, has resulted in an increase in both repetitive stress injuries and acute traumatic injuries in our young athletes. The purpose of this article is to discuss age-related injuries from both a preventative standpoint and a treatment standpoint.

RESUMO

INTRODUCTION: The incidence of patients with fractures is increasing and so is the impact on health care systems and society. To improve patient care, measurement of disabilities and impaired health experiences after traumatic musculoskeletal injuries are important. Next to objective clinical parameters, PROM(I)S can be used to map health domains important to patients. We aimed to objectify different aspects of (health-related) quality of life in fracture patients, including the ability to participate in social roles and activities using PROMIS among other PROMs. METHODS: An observational cohort study was performed in which health-related quality of life in fracture patients was measured. Patients aged 18 year and older either treated conservatively or surgically between November 2020 and June 2022 were included. Participants were followed for a maximum of one year and completed the following PROMs: PROMIS-CAT physical function, PROMIS-CAT pain interference, PROMIS-CAT ability to participate in social roles and activities and LEFS or QDASH. We applied a univariate linear mixed model to evaluate significance of improvement. RESULTS: Seven hundred-forty six patients with a mean age of 54.4 years were included. Mean PROMIS scores were structurally inferior in the lower extremity (LE) fracture group in comparison with the upper extremity (UE) fracture group. For "PROMIS physical function", UE fracture patients performed better and showed physical progression earlier. For "PROMIS pain interference", UE fracture patients experienced fewer limitations, but it took longer to experience improvement in this group. For "PROMIS ability to participate in social roles", significant improvement was only seen in the UE fracture group at one year follow up. CONCLUSION: Upper -and lower extremity fractures can have a significant impact on physical function and social health. Patients with UE fractures tend to have fewer limitations compared to LE fracture patients. Physical function and pain interference is most impaired shortly after the injury in all fracture patients and show significant changes over time, social health improves less over time. Moment of measurement should be based on type of fracture and can differ between individual patients, but when generic measures and outcomes are desirable, PROMIS questionnaires can potentially be used measurement.

RESUMO

Reports of children's play-related injuries have remained stagnant according to epidemiology studies of the past 3 decades. This article provides a unique look into the context of playground injuries within an entire school district, demonstrating the prevalence of these injuries. This study reports that playgrounds are the leading location of school injury, comprising one-third of all elementary school injuries. This study found that while head/neck injuries were the most commonly injured body region within the playground environment, the proportion of head/neck injuries decreased with age, whereas the proportion of extremity injuries increased with age. At least 1 upper extremity injury required outside medical attention for every 4 that were treated on-site, making upper extremity injuries roughly twice as likely to require outside medical attention as injuries to other body regions. The data in this study are useful for interpreting injury patterns in the context and evaluation of existing safety standards for playgrounds.

RESUMO

OBJECTIVES: The authors report no conflict of interest.To determine if short-term immobilization with a rigid long arm plaster elbow splint after surgery of the arm, elbow, or forearm results in superior outcomes compared with a soft dressing with early motion. DESIGN: Prospective Randomized Control Trial. SETTING: Academic Medical Center. PATIENT SELECTION CRITERIA: Patients undergoing operative treatment for a mid-diaphysis or distal humerus, elbow, or forearm fracture were consented and randomized according to the study protocol for postoperative application of a rigid elbow splint (10-14 days in a plaster Sugar Tong Splint for forearm fracture or a Long Arm plaster Splint for 10-14 for all others) or soft dressing and allowing immediate free range of elbow and wrist motion (range of motion [ROM]). OUTCOME MEASURES AND COMPARISONS: Self-reported pain (visual analog score or VAS), Healthscale (0-100, 100 denoting excellent health), and physical function (EuroQol 5 Dimension or EQ-5D) surveyed on postoperative days 1-5 and 14 were compared between groups. Patient-reported pain score (0-10, 10 denoting highest satisfaction) at week 6, time to fracture union, ultimate disabilities of the arm, shoulder, and hand score, and elbow ROM were also collected for analysis. Incidence of complications were assessed. RESULTS: Hundred patients (38 men to 62 women with a mean age of 55.7 years) were included. Over the first 5 days and again at postop day 14, the splint cohort reported a higher "Healthscale" from 0 to 100 than the nonsplint group on all study days ( P = 0.041). There was no difference in reported pain between the 2 study groups over the same interval ( P = 0.161 and 0.338 for least and worst pain, respectively), and both groups reported similar rates of treatment satisfaction ( P = 0.30). Physical function ( P = 0.67) and rates of wound problems ( P = 0.27) were similar. Additionally, the mean time to fracture healing was similar for the splint and control groups (4.6 ± 2.8 vs. 4.0 ± 2.2 months, P = 0.34). Ultimate elbow ROM was similar between the study groups ( P = 0.48, P = 0.49, P = 0.61, and P = 0.51 for elbow extension, flexion, pronation, and supination, respectively). CONCLUSIONS: Free range of elbow motion without splinting produced similar results compared with elbow immobilization after surgical intervention for a fracture to the humerus, elbow, and forearm. There was no difference in patient-reported pain outcomes, wound problems, or elbow ROM. Immobilized patients reported slightly higher "healthscale" ratings than nonsplinted patients and, however, reported similar rates of satisfaction. Both treatment strategies are acceptable after upper extremity fracture surgery. LEVEL OF EVIDENCE: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

Introducción y objetivo: El colgajo lateral del brazo es un recurso de cobertura para el cirujano de mano que tiene una amplia variedad de usos y aplicaciones por su versatilidad y facilidad de recolección con poca morbilidad del sitio donante. El objetivo de este estudio es documentar las principales variantes anatómicas y establecer puntos de referencias para el desarrollo y mejoramiento de las técnicas quirúrgicas actuales en una muestra de población colombiana. Material y métodos: Estudio descriptivo anatómico de 10 miembros superiores de cadáveres frescos congelados en los que realizamos disecciones para documentar las principales perforantes del colgajo lateral del brazo en población colombiana. Tomamos mediciones de distancia de las perforantes al epicóndilo lateral y sacamos proporciones según porcentajes del tamaño de la extremidad. Igualmente, cuantificamos número de perforantes en cada cuadrante y diámetro de los pedículos. Resultados: En el colgajo lateral del brazo, el orden de aparición de las perforantes de distal a proximal correspondió al 13, 19, 26 y 35% de la distancia del brazo (entre el epicóndilo y el acromion); en el segundo cuadrante encontramos la mayoría de las perforantes, la segunda y la cuarta, tuvieron menor variación con respecto a las demás perforantes, los pedículos proximales presentaron un mayor diámetro que los distales. Encontramos el nervio radial a la salida del tabique intermuscular en promedio a 14.08 cm (+/- 0.83) del epicóndilo, siendo esta referencia clave para una disección cuidadosa con el fin de evitar la lesión del mismo. Conclusiones: En nuestra población de estudio, el colgajo lateral del brazo posee una gran versatilidad, con un buen número de perforantes para su nutrición que le permite al cirujano múltiples opciones de cobertura...(AU)


Background and objective: The lateral arm flap is a coverage resource for the hand surgeon that has a wide variety of uses and applications due to its versatility and ease of collection with little morbidity from the donor site. The aim of this research is to carry out dissections of the lateral arm flap in cadavers of the Colombian population to describe the main anatomical vari-ants and establish reference points for the development and improvement of current surgical techniques. Methods: Anatomical descriptive study of 10 upper limbs from fresh-frozen cadavers in which dissections were performed to document the main perforators of the lateral flap of the arm in the Colombian population. Distance measurements were taken from the perforators to the lateral epicondyle and ratios were obtained according to percentages of limb size. Likewise, the number of perforators in each quadrant and the diameter of the pedicles were quantified. Results: The results showed that in the lateral arm flap the order of appearance of the perforators from distal to proximal corresponds to 13, 19, 26 and 35% of the distance of the arm (between the epicondyle and the acromion); most of the perforators were found in the second quadrant, the second and fourth have less variation compared to the other perforators, the proximal pedicles have a larger diameter than the distal ones, the radial nerve was found at the exit the intermuscular septum on average 14.08 cm (+/- 0.83) from the epicondyle, this is a key reference for a careful dissection in order to avoid injury to it. Conclusions: In our study population, the lateral arm flap is highly versatile with a good number of perforators for its nutrition, which allows the surgeon multiple coverage options.

RESUMO

BACKGROUND: Elbow valgus instability is a risk factor for elbow medial collateral ligament injury. This study aimed to investigate the relationship between shoulder range of motion and elbow valgus instability using an ultrasound imaging system. A questionnaire and ultrasound examination were used for the study. METHODS: Thirty-seven high school baseball players (15-18 years) with no history of shoulder or elbow disorders were included. Shoulder range of motion was measured at 90° of adduction, 10° of horizontal adduction, and 90° of elbow flexion in the supine resting position. To evaluate elbow valgus instability, an ultrasound imaging system was used to measure the shortest distance from the apex of the ulnar capitulum to the humeral glenoid with 2.5 kg of valgus stress applied to the ulnohumeral joint. The presence of elbow valgus instability was determined by the value obtained by subtracting the joint space distance on the non-throwing side from that on the throwing side. Student's t-test was applied for the range of shoulder rotation between the two groups, and Pearson's correlation coefficient was used for the relationship between the range of shoulder rotation and elbow instability. Statistical significance was set at 5%. RESULTS: The range of internal and total shoulder rotation was significantly lower in participants with elbow valgus instability than those without elbow valgus instability (P<0.001). In addition, a significant moderate correlation was found in the range of internal (r=0.608, P<0.001) and total shoulder (r=0.479, P<0.001) rotations. CONCLUSIONS: Decreased shoulder range of motion may affect elbow valgus instability.

RESUMO

BACKGROUND: Young baseball players with medial elbow injuries are known to have high forearm flexor-pronator muscle elasticity; however, the causal relationship between forearm muscle elasticity and the occurrence of medial elbow injuries remains unclear. PURPOSE/HYPOTHESIS: The purpose of this study was to determine whether the forearm flexor-pronator muscle elasticity is a risk factor for medial elbow injury in young baseball players. It was hypothesized that high flexor carpi ulnaris (FCU) elasticity would be a risk factor for medial elbow injuries. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: Young baseball players (aged 9-12 years) with no history of elbow injuries underwent examination during which the strain ratios (SRs) of the pronator teres, flexor digitorum superficialis, and FCU muscles were measured using ultrasound strain elastography as an index of elasticity. Additionally, the participants completed a questionnaire assessing age, height, weight, months of experience as a baseball player, position in baseball, number of training days per week, number of throws per day, and elbow pain during throwing; then the range of motion of the shoulder and hip internal/external rotation were measured. One year after the baseline measurements, the occurrence of new medial elbow injuries was evaluated. Multivariate logistic regression analysis was subsequently conducted to determine risk factors for medial elbow injuries. Cutoff points for significant SR values obtained from the multivariate logistic regression analysis were calculated using the receiver operating characteristic curve. RESULTS: Of the 314 players, 76 (24.2%) were diagnosed with medial elbow injury. Multivariate logistic regression analysis showed that a 0.1 increase in the SR of the FCU muscle (odds ratio [OR], 1.211; 95% CI, 1.116-1.314) and number of throws per day (OR, 1.012; 95% CI, 1.001-1.022) were significantly associated with medial elbow injuries. Receiver operating characteristic curve analyses revealed that the optimal cutoff for the SR of the FCU muscle was 0.920 (area under the curve, 0.694; sensitivity, 75.0%; specificity, 56.7%). CONCLUSION: Increased FCU elasticity is a risk factor for medial elbow injury. Evaluation of the FCU elasticity may be useful in identifying young baseball players at high risk of medial elbow injuries and may facilitate prevention of medial elbow injury. As shown by the results of multivariate logistic regression analysis, FCU elasticity itself may be useful in identifying young baseball players at high risk of elbow injuries. However, we believe that other factors, such as the number of pitches per day, need to be considered to improve its accuracy.

RESUMO

In baseball pitchers the elbow is exposed to high and repetitive loads (i.e. external valgus torque), caused by pitching a high number of balls in a practice session or game. This can result in overuse injuries like the ulnar collateral ligament (UCL) injury. To understand injury mechanisms, the effect of repetitive pitching on the elbow load magnitude and variability was investigated. In addition, we explored whether repetitive pitching affects elbow muscle activation during pitching. Fifteen pitchers threw each 60 to 110 balls. The external valgus torque and electromyography of three elbow muscles were quantified during each pitch. Linear mixed model analyses were performed to investigate the effect of repetitive pitching. On a group level, the linear mixed models showed no significant associations of repetitive pitching with valgus torque magnitude and variability and elbow muscle activity. Significant differences exist between pitchers in their individual trajectories in elbow valgus torque and muscle activity with repetitive pitching. This shows the importance of individuality in relation to repetitive pitching. In order to achieve effective elbow injury prevention in baseball pitching, individual characteristics of changes in elbow load and muscle activity in relation to the development of UCL injuries should be investigated.

RESUMO

In this article, we discuss the use of three-dimensional (3-D) printed patient-specific implants in the management of upper extremity fractures. Traditional fracture fixation methods involve the use of standard-sized implants, which may not adequately address the needs of every patient, particularly those who have complications related to fracture nonunion or malunion and those who have significant bone loss. The benefits and limitations of this technology are also discussed, along with considerations for implementation in clinical practice. Overall, the use of 3-D printed patient-specific implants holds promise for improving the accuracy and efficacy of upper extremity fracture management.

RESUMO

Perioperative optimization in upper extremity fracture care must balance the need for timely treatment with the benefits of medical optimization. Care pathways directed at optimizing glycemic control, chronic anticoagulation, smoking history, nutrition, and frailty can reduce surgical risk in upper extremity fracture care. The development of multidisciplinary approaches that tie risk modification with risk stratification is needed.
