RESUMO

Metacarpal stress fractures, although rare in the general population, are not uncommon in high performance athletes and may be seen in individuals with chronic pain associated with sports activity and with no history of acute trauma. Stress fracture fixation in skeletal long bones with different methods and implants have been discussed in the literature, both for patients who had conservative treatment failure and prophylactically. We describe the use of intramedullary cannulated screw fixation for the treatment of a 26-year-old professional boxer who complained of hand pain and swelling with 18 months evolution. After 30 days of post-operative evolution, the patient had no pain on palpation of the metacarpal base and, after three months, he was back to boxing. This is a level V evidence study. Written informed consent was obtained from the patient for publication of this case report and accompanying images.

RESUMO

INTRODUCTION: Stress fractures are injuries produced by the overuse of certain extremities, generating repetitive fatigue in the bone with insufficient rest periods and hormonal disorders, among others. High osteoclastic activity and lower activity of the osteoblasts at the cortical level occurs. OBJECTIVE: To determine the factors associated with a stress fracture in a single medical center of the Peruvian navy. METHODS: We conducted an observational, analytical case-control study. The dependent variable was stress fracture confirmed by magnetic resonance imaging of the patients; the independent variables were age, sex, calcemia, socioeconomic status, and time of daily physical activity. All data were extracted from the medical records. Crude and adjusted odds ratios were calculated with 95% confidence intervals. RESULTS: The sample was comprised of 238 patients (119 cases and 119 controls), of which 79.8% were male, and 20.2% were female; the average age was 20.25. In the bivariate analysis, stress fractures were associated with male sex (odds ratio 3.00; 95% confidence interval 1.51 to 5.95), hypocalcemia (2.83; 2.32 to 3.44), more than two hours of daily physical activity (24.7; 12.51 to 48.95) and socioeconomic level C (6.66; 2.82 to 15.74). Time dedicated to physical activity (adjusted odds ratio 44.46; 95% confidence interval 17.93 to 110.22) and socioeconomic level C (adjusted odds ratio 22.57; 95% confidence interval 7.03 to 72.74) were associated in the multivariate analysis. CONCLUSION: We found that stress fractures were associated with physical activity time and a lower socioeconomic level. Further studies are needed to evaluate the relationship with other factors in the military population of Peru.

INTRODUCCIÓN: Las fracturas por estrés son lesiones producidas por el sobreuso de ciertas extremidades, generando fatigas repetitivas en el hueso con insuficientes periodos de descanso, trastornos hormonales, entre otras. Se produce una elevada actividad osteoclástica y una menor actividad de los osteoblastos a nivel cortical. OBJETIVO: Determinar los factores asociados a fractura por estrés en un centro médico de la Marina de Guerra de Perú. METODOLOGÍA: Se realizó una investigación de tipo observacional analítica de casos y controles. La variable dependiente fue la fractura por estrés, confirmada por resonancia magnética de los pacientes. Las variables independientes fueron edad, sexo y nivel de calcemia tomadas a partir de la historia clínica; el nivel socioeconómico y tiempo de actividad física diaria fueron datos recogidos mediante encuesta. Se obtuvieron los Odds ratio crudos y ajustados con un intervalo de confianza de 95%. RESULTADOS: Se trabajó con un total de 238 pacientes (119 casos y 119 controles), de los cuales 79,8% fueron varones y 20,2% fueron mujeres; la media de edad fue de 20,25 años. En el análisis bivariado se encontró asociación de fracturas por estrés con el sexo masculino (Odds ratio: 3,00; intervalo de confianza 95%: 1,51 a 5,95), hipocalcemia (Odds ratio: 2,83; intervalo de confianza 95%: 2,32 a 3,44), más de dos horas de actividad física diaria (Odds ratio: 24,74; intervalo de confianza 95%: 12,51 a 48,95) y un nivel socioeconómico C (Odds ratio: 6,66; intervalo de confianza 95%: 2,82 a 15,74). Mantuvieron su asociación en el análisis multivariado el tiempo de actividad física (Odds ratio: 44,46; intervalo de confianza 95%: 17,93 a 110,22) y el nivel socioeconómico C (Odds ratio: 22,57; intervalo de confianza 95%: 7,03 a 72,74). CONCLUSIÓN: Las fracturas por estrés estuvieron asociadas al tiempo de actividad física y a un nivel socioeconómico menor. Son necesarios más estudios para evaluar la relación con otros factores en la población militar de Perú.

RESUMO

A 27 years old sedentary woman presented bilateral femoral neck stress fractures after having clinically recovered from anorexia nervosa and was treated with bilateral internal fixation. CONCLUSION: Although light exercise is usually considered after recovery from anorexia nervosa to improve bone quality, this case of a sedentary patient suggests that weight gain, per se, could increase the stress fracture risk. Because of the physiological and psychological characteristics, these patients should be treated with a multi-disciplinary approach.

RESUMO

BACKGROUND: Humeral stress fractures are rare injuries usually related to sports practice and joint overload without a direct trauma. A proximal humeral stress fracture has never been reported in a CrossFit athlete. CASE PRESENTATION: We report a stress fracture in the humerus of a 22-year-old woman after intense CrossFit training. Patient's previous medical history included amenorrhea and reduced Vitamin D levels. The patient was treated conservatively and resumed CrossFit training after she was advised not to until follow up imaging. CONCLUSIONS: We present the MRI features of the case and emphasize the difficulties in diagnosis due to multiple possible causes of shoulder pain in a CrossFit athlete and by negative findings on early radiographs. Hormonal variations, Vitamin D insufficiency and the patient's attitude towards exercise were important factors that contributed for the stress injury after weight-lifting in CrossFit.

RESUMO

OBJECTIVES: The aim of this study was to document the incidence of preceding and subsequent fractures to the patellar fractures in cats with patellar fractures and dental anomaly syndrome. METHODS: Records of cats with patellar fracture and dental anomaly syndrome were retrieved from the combined databases at the University of Bristol, UK, and Exclusively Cats Veterinary Hospital, USA. A request was made to complete a questionnaire to obtain long-term follow-up of these cats with respect to their current status and fractures to other bones; radiographs and histories were requested and were reviewed for treatment of ongoing fractures and outcome. RESULTS: Of the 191 cases reported with this syndrome, 92 cats (48.2%) had dental anomalies and 78 (40.8%) had fractures to other bones; 21 cats sustained the fractures preceding the patellar fractures and 57 subsequently. In total, there were 175 fractures: acetabulum (25%), tibia (22%), ischium (15.4%), humeral condyle (13.7%), calcaneus (5.1%), ilium (5.1%), pubis (3.4%) and other bones (10.2%). The majority of these fractures were characteristic of insufficiency (stress) fractures with a very similar configuration in each bone. CONCLUSIONS AND RELEVANCE: A high proportion of cats with patellar fracture and dental anomaly syndrome will have preceding or subsequent fractures to their patellar fractures. In this study, >10% of cats suffered characteristic fractures preceding the patellar fractures. The presence of these fractures should alert the veterinarian to the possibility that the cat is affected by patellar fracture and dental anomaly syndrome.

RESUMO

En la actualidad es cada vez mayor el número de adultos jóvenes que inician actividad deportiva sin valoración previa de su acondicionamiento físico. En los atletas maduros, con mayor riesgo de presentar hueso osteoporótico, pueden aparecer fracturas por estrés ante traumatismos de menor intensidad repetitivos. En el dolor de cadera en el adulto es importante tener presente la fractura por estrés de cuello femoral, realizando las maniobras exploratorias que permitan su diagnóstico y pedir la prueba de imagen más indicada. Ante una alta sospecha y estudio radiográfico normal debe considerarse la realización de TAC o RMN. El diagnóstico precoz y tratamiento oportuno de esta patología disminuye el riesgo de complicaciones y ofrece la posibilidad de optimizar el uso de recursos.

The number of young adults who start sports activity without prior assessment of their physical conditioning is increasing. In mature athletes, with a higher risk of presenting osteoporotic bone, stress fractures may occur due to repetitive minor trauma. When assesing hip pain in adults it is important to keep in mind femoral neck stress fracture, as well as how to perform exploratory maneuvers that allow diagnosis and request the most appropriate imaging test. In case of high suspicion and normal radiographic study, CT or MRI should be considered. Early diagnosis and timely treatment of this pathology reduces the risk of complications and offers the possibility of optimizing the use of resources.

RESUMO

We present the case of an 81-year-old woman who was followed up by the Rheumatology Service for osteoporosis and treated with bisphosphonates for more than five years. She reported a fracture of the distal third of the contralateral femur by a low energy mechanism, treated with retrograde intramedullary nailing the previous year. She presented a clinic of cruralgia and left gonalgia, without previous trauma. A scintigraphy and radiographs were performed to support the diagnosis of stress fracture of the distal third of the left femur and osteonecrosis of the left internal femoral condyle. Thinking about the possible complications of performing two interventions in an elderly patient, we decided to complete the treatment in a single time and by the same surgical approach, trying to resolve the osteonecrosis and the fracture at the same time, with the objective of an early rehabilitation and lower morbidity. A femoral retrograde prophylactic nailing was performed to stabilize the stress fracture and a retentive primary knee prosthesis was implanted for the posterior cruciate ligament by the same surgical approach. There were no incidents in the immediate postoperative period, with ambulation beginning with help 48 hours after the intervention. The fracture consolidated and the patient presented a good functional result of the knee, both in the immediate postoperative period and at three years of follow-up.

Presentamos el caso de una mujer de 81 años de edad, en seguimiento por el Servicio de Reumatología por osteoporosis y tratada con bifosfonatos durante más de cinco años. Refirió una fractura del tercio distal del fémur contralateral por mecanismo de baja energía, tratada con enclavado intramedular retrógrado el año anterior. Presentó una clínica de cruralgia y gonalgia izquierda, sin traumatismo previo. Se le realizó una gammagrafía y radiografías que apoyaron el diagnóstico de fractura de estrés del tercio distal del fémur izquierdo y osteonecrosis del cóndilo femoral interno izquierdo. Pensando en las posibles complicaciones de llevar a cabo dos intervenciones en una paciente de avanzada edad, se decidió efectuar el tratamiento en un tiempo y por el mismo abordaje quirúrgico, tratando de resolver la osteonecrosis y la fractura a la vez, con el objetivo de una rehabilitación precoz y menor morbilidad. Se realizó un enclavado profiláctico retrógrado femoral para estabilizar la fractura de estrés y se implantó una prótesis de rodilla primaria retentiva para el ligamento cruzado posterior por el mismo abordaje quirúrgico. No hubo incidencias en el postoperatorio inmediato; se inició deambulación con ayuda a las 48 horas de la intervención. La fractura consolidó y la paciente presentó un buen resultado funcional de la rodilla, tanto en el postoperatorio inmediato como a los tres años de seguimiento.

RESUMO

Las denominadas fracturas por fatiga o por estrés ocurren en un hueso normal sometido a reiterados episodios de esfuerzo, aunque de menor requerimiento para causar una fractura aguda. Se presenta a una paciente de 63 años de edad, obesa, con antecedentes de salud anterior que comienza a presentar dolor en ambas regiones de la articulación de la cadera, limitando los movimientos e imposibilitando la marcha. Se le realizaron estudios de imagen donde se le diagnosticó una fractura bilateral del cuello femoral, la izquierda de mejor identificación que la derecha. El tratamiento consistió en osteosíntesis de la fractura izquierda con clavo deslizante, y tratamiento conservador mediante reposo de la cadera derecha. La evolución fue satisfactoria, a los 3 meses habían desaparecido los síntomas y a los 6 meses la paciente deambulaba sin dificultad. La asistencia temprana a esta afección es importante para decidir la terapéutica a emplear y de esta manera evitar las complicaciones(AU)

The so called fatigue or stress fractures occur in a normal bone subjected to repeated episodes of stress, albeit of lesser requirement to cause an acute fracture. We present a 63-year-old obese patient with a history of previous health that begins to present pain in both regions of the hip joint, limiting movements and making gait impossible. Imaging studies were performed in which a bilateral fracture of the femoral neck was diagnosed, the left being better identified than the right one. The treatment consisted of osteosynthesis of the left fracture with a sliding nail, and conservative treatment by resting the right hip. The evolution was satisfactory, at 3 months the symptoms had disappeared and at 6 months the patient walked without difficulty. Early care for this condition is important in deciding which therapy to use and thus avoid complications(AU)

RESUMO

Bisphosphonates (BPs) are the most widely used drugs to treat osteoporosis. However, recent reports associated to long-term BPs use with atypical low-impact fractures and prodromal pain. It is estimated that 26% of the cases of atypical fractures associated with the long-term use of BPs show delayed healing or nonunion. Teriparatide [PTH1-34] (TPTD) is an anabolic drug shown to be effective in stimulating bone formation. The aim was to describe the course of a right diaphyseal femoral fracture sustained by a patient on long-term BPs treatment. A 57-year-old postmenopausal Caucasian female presented with delayed healing of a right femoral diaphyseal fracture 10 months after the fracture, despite having received orthopedic treatment. The fracture was preceded by progressive, severe, and bilateral thigh pain. Her medical history included osteopenia that was treated with alendronate over 7 years. On presentation at our clinic, the patient ambulated with the aid of a walking cane. The diagnosis was an atypical right femoral fracture associated with long-term alendronate use. The levels of the following parameters were measured: mineral metabolism laboratory: intact parathormone, 40 ng/mL (reference values (rv): 10-65 ng/mL); 25-hydroxyvitamin D, 40 ng/mL (rv: >30 ng/mL); serum Crosslaps, 318 ng/mL (rv: 80-590 ng/mL); and bone-specific alkaline phosphatase, 76UI/L (rv: 31-95UI/L)]. Magnetic resonance imaging of the left femur was performed, which revealed a diaphyseal stress fracture. She was prescribed 20 µg/day of subcutaneous (s.c.) TPTD (PTH1-34, Forteo; Eli Lilly Co., Indianapolis, IN, United States). A computed tomography scan performed 3 months later showed that the fracture had healed; the patient was able to resume her usual activities. Twenty micrograms per day of s.c. TPD accelerated the healing of the atypical fracture associated with long-term alendronate therapy, allowing a fast recovery of ambulation and quality of life.

RESUMO

One of the first steps to be taken in order to reduce sports injuries such as stress fractures is to have in-depth knowledge of the nature and extent of these pathological conditions. We present a case report of a stress fracture of the acetabular roof caused through motocross. This type of case is considered rare in the literature. The description of the clinical case is as follows. The patient was a 27-year-old male who started to have medical follow-up because of uncharacteristic pain in his left hip, which was concentrated mainly in the inguinal region of the left hip during motocross practice. After clinical investigation and complementary tests, he was diagnosed with a stress fracture of the acetabular roof.

RESUMO

Stress fractures were first described in Prussian soldiers by Breithaupt in 1855. They occur as the result of repeatedly making the same movement in a specific region, which can lead to fatigue and imbalance between osteoblast and osteoclast activity, thus favoring bone breakage. In addition, when a particular region of the body is used in the wrong way, a stress fracture can occur even without the occurrence of an excessive number of functional cycles. The objective of this study was to review the most relevant literature of recent years in order to add key information regarding this pathological condition, as an updating article on this topic.

A fratura por estresse foi descrita inicialmente em soldados prussianos por Breithaupt em 1855 e ocorre como o resultado de um número repetitivo de movimentos em determinada região que pode levar a fadiga e desbalanço da atuação dos osteoblastos e osteoclastos e favorecer a ruptura óssea. Além disso, quando usamos uma determinada região do corpo de maneira errônea, a fratura por estresse pode ocorrer mesmo sem que ocorra um número excessivo de ciclos funcionais. O objetivo deste estudo é revisar a literatura mais relevante dos últimos anos para agregar as principais informações a respeito dessa patologia em um artigo de atualização do tema.

RESUMO

OBJECTIVE: To analyze and compare the vertical component of ground reaction forces and isokinetic muscle parameters for plantar flexion and dorsiflexion of the ankle between long-distance runners, triathletes, and nonathletes. METHODS: Seventy-five males with a mean age of 30.26 (±6.5) years were divided into three groups: a triathlete group (n=26), a long-distance runner group (n = 23), and a non-athlete control group. The kinetic parameters were measured during running using a force platform, and the isokinetic parameters were measured using an isokinetic dynamometer. RESULTS: The non-athlete control group and the triathlete group exhibited smaller vertical forces, a greater ground contact time, and a greater application of force during maximum vertical acceleration than the long-distance runner group. The total work (180º/s) was greater in eccentric dorsiflexion and concentric plantar flexion for the non-athlete control group and the triathlete group than the long-distance runner group. The peak torque (60º/s) was greater in eccentric plantar flexion and concentric dorsiflexion for the control group than the athlete groups. CONCLUSIONS: The athlete groups exhibited less muscle strength and resistance than the control group, and the triathletes exhibited less impact and better endurance performance than the runners.

RESUMO

As fraturas de stress do gancho do hamato estão geralmente associadas com atividades esportivas que utilizam tacos, raquetes e bastões. Devido à ausência de um trauma óbvio, o diagnóstico exige maior conhecimento desta lesão e alto índice de suspeição. Os autores relatam o caso de um jogador de golfe com fratura de stress do gancho do hamato, com diagnóstico e acompanhamento realizados por ressonância magnética e tomografia computadorizada multislice.

Stress fractures of the hook of the hamate are related to sports that use devices such as golf clubs, rackets and baseball bats. Because usually there is no history of obvious trauma, the diagnosis necessitates better knowledge of the lesion and high index of suspicion. The authors report a case of stress fracture of the hook of the hamate in a golf player with diagnosis and follow-updone with magnetic resonance and multislice computer tomography.
