RESUMO

OBJETIVO Comparar los resultados funcionales obtenidos en dos cohortes de pacientes ancianos tratados de forma quirúrgica (artroplastia reversa de hombro) versus tratamiento conservador. MATERIAL Y METODOS Estudio ambispectivo, no aleatorizado. Se incluyeron pacientes de 75 años o más, 15 tratados de forma quirúrgica y 16 siguieron tratamiento conservador. Seguimiento mínimo de 12 meses. A los 3, 6 y 12 meses de la fractura evaluamos las escalas ASES, Constant-Murley and Disabilities of the Arm, Shoulder and Hand score (DASH) y EVA. Además evaluamos los resultados radiológicos y las complicaciones. RESULTADOS No encontramos diferencias significativas para las escalas ASES, DASH, ni EVA .El grupo tratado de forma quirúrgica obtuvo a los 12 meses una puntuación media en la escala Constant mayor, diferencia estadísticamente significativa(75.1 þ/-10.3 vs. 51.9 þ/-12.4 p » 0.001). Además presentaban mayor rango de movilidad para flexión y rotación externa (128.9 þ/-17 versus 99.3 þ/-20.1 p » 0.001, and 35.7 þ/-13.9 vs. 23.4 þ/-15.5 p » 0.032). El 43% de los pacientes tratados mediante artroplastia reversa presentaban tuberosidades normoposicionadas y mejores resultados en las escalas versus pacientes con tuberosidades ausentes o malposicionadas. El grupo sometido a cirugía no presentó mayor tasa de complicaciones.CONCLUSIONES El tratamiento conservador en las fracturas de EPH en tres y cuatro fragmentos en pacientes ancianos ofrece buenos resultados en cuanto a dolor y funcionalidad en la mayoría de pacientes. Falta por definir qué pacientes por tener alta demanda funcional serían candidatos a tratamiento quirúrgico de entrada

OBJECTIVE This study compared functional results in two cohorts of older adults with three- and four-part proximal humeral fractures (PHFs) per Neer's classification treated with reverse shoulder arthroplasty (RSA) or nonoperative management. MATERIALS AND METHODS Ambispective, non-randomized study with two cohorts of patients aged 75 or older treated with RSA (n » 15) or nonoperative management (n » 16) with a minimum follow-up period of 12 months. We analyzed the American Shoulder and Elbow Surgeons (ASES), Constant-Murley, and Disabilities of the Arm, Shoulder, and Hand (DASH) scores and the visual analog scale (VAS) for pain at 3, 6, and 12 months. In addition, we recorded radiological findings and surgical complications. RESULTS The mean Constant-Murley score at 12 months was significantly higher for the RSA group (75.1 þ/- 10.3 vs. 51.9 þ/- 12.4, p » 0.001). There were no differences in ASES, DASH, and VAS scores. Statistically significant differences for flexion and external rotation in abduction favored the RSA group (128.9 þ/- 17.0 versus 99.3 þ/- 20.1, p » 0.001, and 35.7 þ/- 13.9 vs. 23.4 þ/- 15.5, p » 0.032, respectively). For the RSA group, tuberosity positioning was correct in 43% of subjects. These patients presented better scores than those with malpositioned or absent tuberosities but with no statistical significance. Complications in the surgical group were not higher. CONCLUSIONS Nonoperative treatment is a valid option regarding pain and functionality in elderly patients with three- and four-part PHFs. Characteristics of patients with high demands who may be candidates for the initial surgical treatment remain to be defined

RESUMO

BACKGROUND: Proximal humeral fractures can progress to osteonecrosis of the humeral head. Hertel developed a binary classification system (12 subtypes) and demonstrated that some patterns have more risk to develop osteonecrosis. Hertel described the prevalence and the risk factors for Humeral head osteonecrosis after osteosynthesis using a Deltopectoral approach. Few studies have evaluated the prevalence and the capacity of Hertel's classification to predict Humeral Head osteonecrosis following osteosynthesis of proximal Humeral fractures through the anterolateral approach. The objectives of this study were to correlate osteonecrosis predictors established by the Hertel classification with the risk of developing osteonecrosis and its prevalence after osteosynthesis using the anterolateral approach. METHODS: This was a retrospective study of patients who underwent osteosynthesis of proximal humerus fractures using an anterolateral approach. Patients were divided into two groups: high risk for necrosis (group 1) and low risk for necrosis (group 2) according to Hertel's criteria. The overall prevalence of osteonecrosis and the prevalence in each group were calculated. A radiological examination was performed in the true anteroposterior (Grashey), scapular, and axillary views, before and after the operation (minimum 1 year after surgery). A Kaplan-Meier curve was used to assess the pattern of the temporal evolution of osteonecrosis. The groups were compared using the Chi-square test or Fisher's exact test. The unpaired t-test (parametric variables - age) and the Mann-Whitney test (non-parametric time between trauma and surgery) were used. RESULTS: In total, 39 patients were evaluated. The postoperative follow-up time was 14.5 ± 3.3 months. The time to onset of necrosis was 14.1 ± 3.9 months. Sex, age, and time between trauma and surgery did not influence the risk of necrosis. Type 2, 9, 10, 11, and 12, or fractures with posteromedial head extension less than or equal to 8 mm, or diaphysis deviation greater than 2 mm, as well as grouping did not influence the risk for osteonecrosis. CONCLUSIONS: Hertel's criteria were not able to predict the development of osteonecrosis after osteosynthesis of proximal humerus fractures performed through the anterolateral approach. The total prevalence of osteonecrosis was 17.9% with a tendency toward an increased incidence after 1 year of surgical treatment.

RESUMO

Abstract Objectives To describe the functional result of the conservative treatment of displaced proximal humerus fractures (PHF) using the American Shoulder and Elbow Surgeons (ASES) score after 12 months and assess whether the different initial classifications and radiographic measurements are related to clinical results. Methods Forty patients > 60 years old, with displaced PHUs submitted to conservative treatment were evaluated at standardized times (3, 6, and 12 months). The American Society of Shoulder and Elbow Surgeons (ASES), Constant-Murley and Single Assessment Numeric Evaluation (SANE) scales were used as clinical outcomes. Radiographic variables included the Neer and Resch classifications, the presence and displacement of tuberosity fracture, metaphyseal comminution, medial periosteal lesion, and angular and translational deviations of the head in the coronal and sagittal plane. Results The result of the ASES score was 77.7 23.2 for the whole sample, the mean absolute values of the Constant-Murley score were 68.7 16 and 82.6% for the scale relative to the contralateral side. The SANE scale at 12 months was 84.8 19. We observed that the severity of the Neer classification and the coronal plane angular deviation (measured by the head-shaft angle) and the presence of fractures in both tuberosities negatively influenced the ASES score after 12 months of treatment. Conclusion Nonoperative treatment of displaced proximal humerus fractures in elderly patients results in good clinical results. Clinical results are negatively influenced by the angular deviation of the humeral head and the presence of fractures of the greater and lesser tubercles, as well as by the Neer classification.

RESUMO

INTRODUCTION: shoulder hemiarthroplasty is being relegated as a treatment for non-osteosynthetic proximal humerus fractures. Our objective is to analyze the functional results of patients treated with hemiarthroplasty for this reason in our hospital. MATERIAL AND METHODS: cross-sectional descriptive study that includes patients operated between February 2016 and November 2021; 24 patients, with an average follow-up of 44.6 months. Active joint balance, the Constant-Murley test, the DASH questionnaire and current pain (VAS) were collected. The radiographic parameters analyzed were the number of fracture fragments and the consolidation of the tuberosities. RESULTS: a mean of 71.65 ± 13.75 was obtained in the Constant-Murley and 18.14% ± 13.92 in the DASH. For shoulder flexion, the mean was 108.75° ± 41.26; 104.5° ± 43.68 for abduction and 33° ± 14.73 for external rotation. About internal rotation, 60% of the patients reached the scapular plane. Average VAS was 1.25 ± 1.74. Consolidated tuberosities in 90.5%. There were no significant differences comparing the Constant-Murley test, DASH or rotations between both, over and under 65 years old group of patients. Those over 65 years of age obtained a mean flexion of 125.91° ± 26.82 whereas those under 87.78° ± 26.82 (p = 0.038). The mean abduction in those over 65 was 125.45 ± 28.94 vs 78.89 ± 46.29 in the young group (p = 0.012). CONCLUSION: hemiarthroplasty provides quality of life with acceptable functionality and good pain control, therefore it should continue to be an alternative to consider in selected patients.

INTRODUCCIÓN: la hemiartroplastía de hombro está siendo relegada como tratamiento de fracturas de húmero proximal no osteosintetizables. Nuestro objetivo es analizar los resultados funcionales de los pacientes tratados con hemiartroplastía por este motivo en nuestro centro. MATERIAL Y MÉTODOS: estudio descriptivo transversal que incluye a los pacientes intervenidos entre Febrero de 2016 y Noviembre de 2021; 24 pacientes, con un seguimiento medio de 44.6 meses. Fueron recogidos el balance articular activo, el test de Constant-Murley, el cuestionario DASH y el dolor actual (EVA). Como parámetros radiográficos se analizó el número de fragmentos de fractura y la consolidación de las tuberosidades. RESULTADOS: se obtuvo una media de 71.65 ± 13.75 en el Constant-Murley y de 18.14% ± 13.92 en el DASH. Para flexión de hombro la media fue de 108.75° ± 41.26; 104.5° ± 43.68 para abducción y 33° ± 14.73 para rotación externa. En rotación interna 60% llegaba hasta plano interescapular. EVA medio de 1.25 ± 1.74. Tuberosidades consolidadas en 90.5%. No hubo diferencias significativas entre el Constant-Murley, DASH ni rotaciones de pacientes mayores y menores de 65 años. Los mayores de 65 años obtuvieron flexión media de 125.91° ± 26.82 y los menores de 87.78° ± 26.82 (p = 0.038). La abducción media en mayores de 65 fue de 125.45 ± 28.94 versus 78.89 ± 46.29 en el grupo joven (p = 0.012). CONCLUSIÓN: la hemiartroplastía otorga calidad de vida con aceptable funcionalidad y buen control del dolor, por lo que debe continuar siendo una alternativa a tener en cuenta en pacientes seleccionados.

RESUMO

Convulsive seizures caused by hyponatremia occur when this condition is severe and develops quickly, resulting in a brain's adaptive inability to contain brain swelling. Seizures are rarely the cause of shoulder fractures. This is a case report of bilateral humerus fracture following a single epileptic seizure caused by drug hyponatremia, an unconventional event in medical practice. A 69-year-old woman was admitted to the emergency room after a single tonic-clonic seizure with spontaneously ceased sphincter relaxation, showing Glasgow 6. No falls or restraint were reported by observers. When alert, the patient reported pain and difficulty moving both arms. During examination, the movement was li- mited to the right and left. Anteroposterior radiographs revealed bilateral fracture at the neck of humerus. To complement inves- tigation for further lesions, a computed tomography confirmed bilateral fracture-dislocation with impaction of the humeral head with the glenoid. Atraumatic bilateral fracture-dislocation of the humerus after epileptic seizure is a very rare event. It is believed that some of these diagnoses have been neglected due to the difficulty of characterizing the patient's pain in a postictal state. The importance of a detailed physical examination shall be emphasized in risk groups such as the polymedicated elderly.

RESUMO

INTRODUCTION: The quality of reduction in proximal humerus fractures is valuable with radiographic criteria (Neck-shaft angle [NSA]; medial offset [MO]; distance head tuberosity [DHT] and subacromial space [SS]) that predict functionality. These criteria set for other implants are not described for the intramedullary nail. MATERIAL AND METHODS: Observational cohort study, retrospective, with patients 18 years, with osteosynthesis with intramedullary nail (2014 to 2017), evaluating demographic characteristics, severity of injury (Neer classification), progressive radiographic measurements and complications. RESULTS: 84 cases with an average age of 65 ± 2 years and an average follow-up of 13.9 months were analyzed. By Neer rating 40.4% were grade II, 29.7% grade III and 29.7% grade IV. Consolidation in varus increases to 10.7% at the end of follow-up, with Neer III and IV patients. The 140° deformity is prevalent for Neer II (n = 15/34). 30.9% have a change of neck-shaft angle of 10°. Overall 86.9% has HTD changes 5 mm. Cases Neer III/IV 32% has alteration of SS 5 mm. The most common complication is avascular necrosis (AVN) with 44% of cases. CONCLUSIONS: Radiographic measurements have changes in long-term follow-up. Alterations in NSA ( 10o) and SS ( 5 mm) occur in higher proportion of Neer III/IV patients, according to the severity of the fracture, favoring vicious consolidations in varus or valgus and increased presence of AVN.

INTRODUCCIÓN: La calidad de reducción en las fracturas de húmero proximal es posible valorarla a través de criterios radiográficos (ACD = ángulo cervicodiafisario; OM = offset medial; DTC = distancia tuberosidad-cabeza y ES = espacio subacromial), los cuales predicen la funcionalidad. Sin embargo, estos criterios establecidos para otros implantes no están descritos para el clavo centromedular. MATERIAL Y MÉTODOS: Estudio de cohorte observacional y retrospectivo en pacientes 18 años con osteosíntesis con clavo centromedular (durante el período de 2014 a 2017), en donde se evaluaron las características demográficas, severidad de lesión (clasificación de Neer) y las mediciones radiográficas progresivas y complicaciones. RESULTADOS: Se analizaron 84 casos, cuya edad en promedio fue de 65 ± 2 años y la media de seguimiento de 13.9 meses. Por clasificación de Neer: 40.4% fueron grado II; 29.7%, grado III y 29.7%, grado IV. La consolidación en varo aumenta 10.7% al final del seguimiento, siendo aquellos pacientes Neer grado III y IV los más frecuentes. La deformidad 140° predomina para Neer grado II (n = 15/34). En 30.9%, se presenta un cambio de ACD (ACD) 10°. En general, 86.9% tiene cambios de DTC 5 mm. En los casos Neer grado III/IV, 32% tiene una alteración de ES 5 mm. La complicación más frecuentemente es la necrosis avascular (NAV) con 44% de los casos. CONCLUSIONES: Las mediciones radiográficas presentan cambios en valoraciones a largo plazo. Las alteraciones en ACD ( 10o) y ES ( 5 mm) se dan en mayor proporción en aquellos pacientes Neer grado III/IV (acorde con la severidad de la fractura), lo que favorece consolidaciones viciosas en varo o valgo y una mayor presencia de NAV.

RESUMO

Proximal humerus fractures involving an articular head split are rare and complex injuries. In the elderly population, arthroplasty is the optimal treatment, whereas in younger patients, the utility of arthroplasty procedures is limited by concerns of long-term implant survival. As a result, open reduction and internal fixation is still often the first-line treatment option for head-splitting injuries. The traditionally described deltopectoral or anterolateral surgical approaches to the proximal humerus rely on indirect reduction and limited visualization of the articular fragments. We present a case series of younger patients with head-split proximal humerus fractures treated with open reduction and internal fixation through a deltopectoral approach with a subscapularis peel to improve humeral head visualization, reduction, and fixation. The improved reduction may lead to better long-term outcomes and reduce the need for additional surgical procedures. In addition, there were no cases of avascular necrosis in this series.

RESUMO

El tratamiento de las fracturas óseas del miembro superior puede realizarse por métodos cerrados o abiertos. Los cerrados se basan en el principio de inmovilización y/o tracción con materiales externos, mientras que los abiertos utilizan elementos quirúrgicos de fijación interna o externa. Los rayos X(Rx) constituyen la primera y mejor metodología para la evaluación posquirúrgica de estos elementos. El conocimiento básico de los materiales utilizados es necesario para conseguir una buena evaluación e informe médico.

The treatment of bone fractures of the upper limb can be performed by closed or open methods. Closed methods are based on the principle of immobilisation and / or traction with external materials. Instead, open surgical methods use elements of internal or external fixation. The x-ray is the first method of choice in the post-operative evaluation of these elements. A basic knowledge of the materials used is necessary to make a good assessment and medical report.

RESUMO

BACKGROUND: Displaced proximal humeral physeal fractures (PHPF) are rare injuries. Because of the lack of comparative studies, treatment has historically been based on surgeon preference. The purpose of this study was to compare treatment outcomes among skeletally immature patients who underwent operative versus nonoperative treatment for Neer-Horwitz (NH) III or IV PHPF. METHODS: Skeletally immature patients who underwent treatment for a displaced PHPF from 2003 to 2012 were identified. Eligible subjects were invited to complete a validated shoulder outcome instrument (QuickDASH) and a phone survey. A propensity score matching approach was utilized to match subjects who underwent operative treatment to subjects who underwent nonoperative treatment on the basis of age at injury and NH classification. RESULTS: Seventy patients were identified with a NH III or IV PHPF, of whom 32 subjects completed the study. There was also no difference (P=0.5637) in the proportion of subjects who developed a less than desirable treatment outcome in operative group (57.14%, 4/7) as compared with the nonoperative group (42.86%, 3/7). There was also no difference (P=0.5637) in the proportion of subjects who developed a less than desirable treatment outcome in operative group (57.14%, 4/7) as compared with the nonoperative group. Differences in rate of return to preinjury level of activity (P>0.9999), or cosmetic appearance scores (P>0.999) were not significantly different. QuickDASH scores were 1.9 points (95% CI, 3.0-6.9; P=0.3699) higher overall in the nonoperative group as opposed to the operative group. A less than desirable treatment outcome was noted in 4/23 (17.4%) subjects who underwent nonoperative treatment. Subgroup analysis of the nonoperative cases showed that, for every 1 year increase in age at initial injury, the odds of less than desirable outcome increased by a factor of 3.81 (95% CI, 1.31-21.0). CONCLUSIONS: In a matched cohort of patients with proximal humerus physeal fractures, there was no difference in occurrence of complications, rate of return to activity, or cosmetic satisfaction. Functional outcomes were also nonsignificant, but tended to be higher among fractures that underwent nonoperative treatment. Among nonoperatively treated fractures, less than desirable outcomes were more common in older patients, particularly those older than 12 years of age. LEVEL OF EVIDENCE: Level III-therapeutic.
