Resultados del tratamiento funcional de las fracturas del metatarso en las fracturas del primer radio / Results of Functional Treatment of Metatarsal Fractures in First Radius Fractures

Introducción: Las fracturas del metatarso son las lesiones traumáticas más comunes del pie, y las del primer metatarsiano son las cuartas en frecuencia. El tratamiento funcional de las fracturas metatarsianas consiste en el apoyo efectivo y precoz, sin inmovilización del miembro. Objetivo: Comparar la efectividad del tratamiento funcional en las fracturas del primer metatarsiano con los tratamientos convencionales Métodos: Se realizó un estudio analítico, observacional, retrospectivo, de casos y controles, en 102 fracturas del primer metatarsiano durante un período de ocho años. La muestra incluyó a pacientes de ambos sexos, entre 16 y 65 años de edad. Se comparó el tratamiento funcional con los tratamientos ortopédico y quirúrgico. Las fracturas fueron clasificadas según su localización, recomendación terapéutica y tratamiento efectuado. Los resultados fueron evaluados en función de la duración de la incapacidad temporal y las complicaciones. Resultados: 48 fracturas fueron tratadas con el método funcional y 41 mediante descarga e inmovilización. Los 13 pacientes con criterio de indicación quirúrgica fueron intervenidos mediante reducción y osteosíntesis. Se obtuvo una menor duración de la incapacidad y menos complicaciones con el tratamiento funcional que con los tratamientos convencionales. Conclusiones: En los últimos años ha aumentado la tendencia a tratar las fracturas metatarsianas de manera conservadora y muchos autores recomiendan el método funcional como tratamiento de elección. Este proporciona una curación más temprana y ocasiona menos complicaciones que los tratamientos convencionales(AU)

Introduction: Metatarsal fractures are the most common traumatic injuries of the foot, and those of the first metatarsal are the fourth in frequency. The functional treatment of metatarsal fractures consists of effective and early support, without limb immobilization. Objective: To compare the effectiveness of functional treatment in fractures of the first metatarsal with conventional treatments. Methods: An analytical, observational, retrospective, case-control study was conducted on 102 first metatarsal fractures over a period of eight years. The sample included patients of both sexes, between 16 and 65 years of age. Functional treatment was compared with orthopedic and surgical treatments. The fractures were classified according to location, therapeutic recommendation and treatment. The results were evaluated according to the duration of the temporary incapacity and the complications. Results: Forty eight fractures were treated with the functional method and 41 by offloading and immobilization. The thirteen patients with surgical indication criteria were operated by reduction and osteosynthesis. A shorter duration of disability and fewer complications were achieved with functional treatment than with conventional treatments. Conclusions: In recent years, the tendency to treat metatarsal fractures conservatively has increased and many authors recommend the functional method as the treatment of choice. This provides earlier healing and causes fewer complications than conventional treatments(AU)

Primary Treatment of Acute Ankle Sprain: Retrospective Comparison of Cast Immobilization and Functional Ankle Brace / 대한족부족관절학회지

PURPOSE: To compare the efficacy between cast immobilization and functional treatment using an ankle brace as a treatment for acute lateral ankle sprain. MATERIALS AND METHODS: This study reviewed the medical records of 157 acute ankle sprain patients who were treated between 2009 and 2014. A total of 101 cases were included in this study except for cases with a combined injury, and could not be followed up for eight weeks after the first visit. The patients were divided according to the treatment modality: a cast immobilization group (64 cases) and functional treatment group (37 cases). The clinical outcomes were assessed retrospectively based on the medical records of each group. The residual symptoms, such as pain, swelling, and instability, at three weeks after the primary treatment and at the last visit were compared. RESULTS: The residual pain and instability were significantly common in the functional treatment group at three weeks. Five cases (7.8%) of pain and one case (1.6%) of instability were in the cast group whereas nine cases (24.3%) of pain and six cases (16.2%) of instability in functional treatment group (p=0.021, p=0.014). On the other hand, there was no meaningful difference at the last follow-up. Residual pain, swelling, and instability at the last visit were noted in three (4.7%), six (9.4%), and four cases (6.3%) in the cast group, and three (8.1%), three (8.1%), and three (8.1%) were observed in the functional treatment group. Six patients refused cast immobilization. CONCLUSION: Although there was no significant difference at the last follow-up, cast immobilization appears to be more effective than a functional brace in terms of early pain relief and early restoration of ankle stability as a treatment for acute ankle lateral sprain in this study.

Diagnosis and Treatment of Acute Ankle Sprain / 대한족부족관절학회지

Acute sprain of the ankle requires comprehensive history taking and physical examination in diagnosing the type of severity and deciding on the plan of treatment. Literature supports functional treatment as the treatment of choice for grade I and II injuries. During the acute phase, the goal of treatment focuses on controlling pain and swelling. PRICE (protection, rest, ice, compression, and elevation) is a well-established protocol at this phase. There is some evidence that application of ice and use of nonsteroidal anti-inflammatory drugs improves healing and speeds recovery. Then the functional treatment (motion restoration and strengthening exercises) is administered to progress the rehabilitation appropriately in order to facilitate healing and restore the mechanical strength and proprioception. Early mobilization has been shown to result in more rapid return to work and daily activities than immobilization. Grade III injuries still generate controversy in terms of the best management available, and more studies on early mobilization, cast immobilization, or surgery are needed. Even the Cochrane reviews published to date are not conclusive.
