Acute ankle injuries: association between sprain severity and ancillary findings

ABSTRACT Objective To correlate the significance of osseous, chondral, tendon, and ligamentous injuries with anatomical variations in low-grade versus high-grade acute ankle sprains. Methods We retrospectively identified the magnetic resonance imaging findings of acute ankle sprains (<15 days). Participants with a history of previous sprains, arthritis, tumors, infections, or inflammatory conditions were excluded. Images were independently evaluated by two musculoskeletal radiologists and assessed for osseous, chondral, tendon, and ligamentous injuries and anatomical variations. Participants were divided into low-grade versus high-grade sprain groups, according to the presence of a complete tear in at least one component of the lateral ligament complex. Results The final study group comprised 100 magnetic resonance images (mean age, 36 years), the majority of males (54%), the right ankle (52%), and a mean sprain duration of 5 days. Participants with high-grade sprains presented with increased rates of medial malleolus edema (p<0.001), moderate and large articular effusions (p=0.041), and shorter calcaneonavicular distance (p=0.008). Complete tears of the anterior talofibular ligament and calcaneofibular ligaments were observed in 100% and 51.2% of the participants in the High-Grade Group, respectively. The deltoid ligament complex was partially torn in this group (55.8% versus 8.8%, p<0.001). Extensor tendon retinaculum lesions occurred significantly more frequently in this group (41.9%) compared to the overall study population (23%) (p<0.001). Conclusion Participants with high-grade ankle sprains presented with shorter calcaneonavicular distances and increased rates of medial malleolus edema, deltoid complex partial tears, extensor retinaculum lesions, and articular effusion.

Platelet-rich plasma on ankle sprains – efficacy on pain reduction and shorter return to play: A systematic review of available randomized control trials

Background@#The role of platelet-rich plasma (PRP) has been widely studied, but only recently did trials emerge that probed into its potential role in ankle sprains. With the limited available literature, most of the trials results showed that it might have a role in faster healing and pain reduction. @*Objectives@#The purpose of this review is to summarize available studies on ankle sprains in order to identify if there is good initial evidence of its role on return to play (RTP) among active individuals as well as pain reduction. It is also to identify if results were consistent among studies. @*Methodology@#A systematic search of available literature in online databases was done to compare results about outcome measures on pain score and RTP. Included studies are those with a population of 18 years and above treated with PRP with or without post-procedural immobilization. Outcome scorings that assessed pain as a parameter was also included. @*Results@#Three randomized controlled trials and two prospective studies were identified. Results showed an average of 8 weeks to RTP (p-value - 0.006) with decreased pain in ankle sprains treated with PRP and functional therapy. @*Limitation@#Only one randomized controlled trial (RCT) compared PRP with a placebo and a small population of all studies made available. More comparable RCTs are needed to strengthen results of the studies. @*Conclusion@#The use of PRP on ankle sprains may have a potential role in shorter time to RTP and pain reduction.

Clinical observation of contralateral needling combined with Maitland ankle mobilization for chronic ankle sprain / 针灸推拿医学（英文版）

Objective: To observe the efficacy of contralateral needling combined with Maitland ankle mobilization in the treatment of chronic ankle sprain.Methods: A total of 106 patients with chronic ankle sprain were included in the study. They were numbered according to their order of visit, with odd numbers assigned to the control group and even numbers assigned to the observation group, with 53 cases in each group. Patients in the control group were treated with Maitland ankle mobilization, while those in the observation group were given additional contralateral needling treatment. After treatment, we observed the indicators including, ankle circumference, range of motion (ROM) of dorsiflexion, ROM of plantar flexion, thickness of ankle ligaments, and the changes in Baird-Jackson ankle score, American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, and visual analog scale (VAS) score to compare the efficacy between the two groups. Results: After treatment, the total effective rate of the observation group was 94.3％ and was significantly higher than that of the control group (81.1％), indicating statistical significance (P<0.05). After treatment, the ankle circumference of both groups decreased, and the ROM of dorsiflexion and the ROM of plantar flexion increased (P<0.05). The changes in the observation group were more significant, indicating inter-group statistical significance (P<0.05). After treatment, the thickness of the anterior talofibular ligament, calcaneofibular ligament, and posterior talofibular ligament, as well as the VAS scores decreased in both groups; the changes in the observation group were more significant, indicating inter-group statistical significance (P<0.05). After treatment, the Baird-Jackson ankle score and the AOFAS ankle- hindfoot score increased in both groups, and the scores in the observation group were higher than those in the control group, indicating inter-group statistical significance (P<0.05). Conclusion: The efficacy of contralateral needling combined with Maitland ankle mobilization in the treatment of chronic ankle sprain is superior to that of Maitland ankle mobilization alone.

Ankle Sprain in Young Athletes: A 2-Year Retrospective Study at a Multisport Club / Entorse no tornozelo em jovens atletas: Um estudo retrospectivo de 2 anos em um clube multiesportivo

Abstract Objective The present study aimed to analyze ankle sprains in young athletes of basketball, futsal, artistic gymnastics, trampoline, tennis, judo, and volleyball over 2 seasons. Methods Data of 529 athletes in the 1st year and of 495 athletes in the 2nd year of analysis were investigated from the injury record database of a sports club. The following data were considered: the demographic characteristics (age, body mass, height, and sex), the mechanism (contact or noncontact), the severity, the moment at which the injury occurred, and the recurrence. Also, the incidence rate, the injury risk of the first ankle sprain, and the incidence rate ratio between sports were calculated. Results The athletes sustained 124 ankle sprains in the 2 years of analysis. The majority occurred during training (76.6%) and lead to absence from sports practice (75.8%). The injury recurrence was low: 2 athletes (1.6%) had a recurrence in the same year and 5 (4.0%) in the following year. The incidence rate (0.79 to 12.81 per 1,000 hours) and the injury risk (1.14 to 19.44%) varied among sports. Volleyball, basketball, and futsal presented the highest injury rate incidence. Tennis, gymnastics, and trampoline showed the lowest injury rate incidence. Judo showed an incidence rate different from those of basketball and volleyball in the 1st year and similar to those of other sports in the 2nd year. Conclusion Ankle sprain greatly impacted sports practice and presented characteristics that differ among the investigated sports. These findings may contribute to developing preventive injury programs.

Clinical effect of foot-ankle balance massage combined with herbal fumigation in the treatment of acute ankle sprain / 国际中医中药杂志

Objective:To explore the clinical curative effect of foot-ankle balance massage combined with herbal fumigation on acute ankle sprain.Methods:According to random number table method, 62 patients with acute ankle sprain meeting the inclusion criteria in the hospital were divided into control group and observation group between January 2018 and January 2021, 31 in each group. The control group was treated with foot-ankle balance massage, while the observation group added herbal fumigation treatment on the basis of the control group treatment. Both were treated for 7 days. The pain degree was evaluated by Visual Analogue Scale (VAS). The pain sites of ankle joint were evaluated by Kofoed ankle scale. The recovery of ankle and foot function was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS). The levels of plasma substance P, neuropeptide, nerve growth factor (NGF), IL-1β, IL-6 and hs-CRP were detected by enzyme-linked immunosorbent assay. The clinical curative effect was assessed.Results:The differences in total response rate between observation group and control group were statistically significant [96.8% (30/31) vs. 77.4% (24/31)] ( χ 2=5.17, P=0.023). At 1st day, 3rd day and 7th day after treatment, VAS scores in observation group were significantly lower than those in the control group ( t=4.86, 5.19, 3.86, P<0.01), Kofoed scores were significantly higher than those in the control group ( t=2.03, 2.58, 2.46, P<0.05), and AOFAS pain scores were significantly higher than those in the control group ( t=2.61, 2.47, 4.90, P<0.05). After treatment, levels of substance P [(2.94±0.91) mg/L vs. (3.69±0.94) mg/L, t=3.19], neuropeptide [(141.06±16.31) ng/L vs. (165.22±17.63) ng/L, t=3.16] and NGF [(43.65±10.15) ng/L vs. (52.26±10.20) ng/L, t=3.33] in observation group were significantly lower than those in the control group ( P<0.01), and levels of IL-1β, IL-6 and hs-CRP were significantly lower than those in the control group ( t=2.60, 2.64, 2.42, P<0.05). Conclusion:The foot-ankle balance massage combined with herbal fumigation can quickly relieve pain, increase levels of pain substances, reduce levels of inflammatory cytokines and improve curative effect in patients with acute ankle sprains.

Clinical study on Tuina plus physical agents for lateral collateral ligament injury of ankle in gymnasts / 针灸推拿医学（英文版）

Objective: To compare the efficacy of Tuina (Chinese therapeutic massage) plus physical agents and physical agents alone for lateral collateral ligament injury of ankle in gymnasts, and to explore the feasibility of Tuina for injury intervention in competitive athletes.Methods: A total of 64 gymnasts with types Ⅰ-Ⅱ lateral collateral ligament injury of ankle were selected and divided into a control group and an observation group according to a full analysis set based on the intention-to-treat principle, with 32 cases in each group. Patients in the control group received ultrasound and microwave treatment, while those in the observation group received additional Tuina manipulations. The efficacy was evaluated by total effective rate, visual analog scale (VAS) score, and American Orthopedic Foot and Ankle Society ankle-hindfoot scale (AOFAS-AHS) score. Results: The total effective rate was 96.9％ in the observation group and 90.6％ in the control group. There was no statistical difference in the total effective rate between the two groups (P>0.05). The markedly effective rate was 75.0％ in the observation group and 46.9％ in the control group. The markedly effective rate in the observation group was higher than that in the control group (P<0.05). After treatment, the VAS scores of both groups showed a downward trend, and there were statistical differences between different treatment time points in the same group (P<0.05). After one and three months of treatment, the VAS scores of the observation group were lower than those of the control group (P<0.05). There were statistical differences in the AOFAS-AHS score before and after treatment within the same group (P<0.05). After one month of treatment, there was no statistical difference in the AOFAS-AHS score between the two groups (P>0.05). After three months of treatment, the AOFAS-AHS score in the observation group was higher than that in the control group, indicating statistical significance (P<0.05). There was an interaction between time and group (P<0.05). Conclusion: Tuina plus physical agents can improve the symptoms of lateral collateral ligament injury of ankle in gymnasts. This combined treatment is superior to physical agents alone in relieving pain and improving joint functions. Therefore, Tuina plus physical agents can be used as a treatment for lateral collateral ligament injury of ankle in gymnasts.

Is subfibular ossicle excision necessary in the modified Brostr?m procedure for chronic lateral ankle instability? / 中华创伤骨科杂志

Objective:To investigate the effect of subfibular ossicle excision on the clinical efficacy of Brostr?m procedure for chronic lateral ankle instability (CLAI).Methods:From March 2014 to December 2018, 76 patients were treated by the modified Brostr?m procedure using the suture anchor technique for CLAI at Department of Foot & Ankle Surgery, Wuhan Fourth Hospital. Of them, 33 had subfibular ossicles (SFO group) and 43 did not (NSFO group). In the SFO group, there were 19 males and 14 females, aged (28.4±8.6) years; in the NSFO group, there were 21 males and 22 females, aged (27.8±7.4) years. Subfibular ossicles were excised in the SFO group. The 2 groups were compared in terms of American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores and visual analogue scale (VAS) pain scores at preoperation and the final follow-up.Results:The 2 groups were comparable due to insignificant differences between them in their preoperative general data ( P>0.05). All the patients were followed up for 24 to 72 months (average, 28 months). The AOFAS ankle-hindfoot scores improved significantly from 54.5±3.4 to 95.7±2.1 in the SFO group and significantly from 56.2±2.7 to 95.2±2.4 in the NSFO group at the final follow-up; the VAS scores reduced significantly from 5.7±1.8 to 1.6±1.4 in the SFO group and significantly from 5.7±1.6 to 1.7±1.2 in the NSFO group at the final follow-up (all P<0.05). No significant differences were found between the 2 groups in terms of AOFAS or VAS scores at the final follow-up ( P>0.05). Conclusion:Since the modified Brostr?m procedure plus subfibular ossicle excision may result in similar good clinical efficacy as merely the modified Brostr?m procedure may for the CLAI patients without subfibular ossicle, subfibular ossicle excision should be suggested for the CLAI patients with subfibular ossicle.

Effects of wearing an ankle brace on ground reaction forces during jumps in basketball game simulation / Efectos del uso de órtesis de tobillo sobre las fuerzas de reacción del suelo durante los saltos en simulación de juego de baloncesto / Efeitos do uso de órtese de tornozelo sobre as forças de reação do solo durante saltos em simulação do jogo de basquetebol

ABSTRACT Introduction: The use of ankle braces reduces the risk of ankle injuries in basketball players. However, the mechanisms of injury protection provided by the ankle braces in the basketball game are still unknown. Objectives: To analyze the effects of wearing a lace-up ankle brace, and to conduct an exercise protocol that simulated the intensity of the basketball game on ground reaction force (GRF) during basketball-specific vertical jumps. Methods: Eleven male younger basketball players aged under 18 completed 48 vertical jumps, with and without ankle braces, during an exercise protocol composed of four 10-minute periods, simulating the activity profile and intensity of the basketball game as well as the typical intervals between periods. Mediolateral (variables: the greatest medial and lateral peaks) and vertical (variables: vertical peak, impulse peak, impulse at 50 ms of landing, loading rate and jump height) GRF were measured during takeoff and landing for all the jumps performed in the exercise protocol. Results: The use of the ankle brace reduced mediolateral GRF in all periods of the exercise protocol during takeoff and landing ( P < 0.05), without affecting the vertical GRF ( P > 0.05). Mediolateral and vertical GRF (takeoff mediolateral vertical peaks, landing mediolateral peaks, landing impulse peak, takeoff and landing loading rate) increased significantly during four subsequent 10-minute periods ( P < 0.05). However, for mediolateral GRF, the increase overtime was higher without braces. Conclusions: The use of the ankle brace reduced the mediolateral GRF on the lower limb, while there was a progressive increase in the external load applied to the body during the vertical jumps in the subsequent periods of the exercise protocol performed at the same intensity of the basketball game. Level of evidence I; Randomized clinical trial .

RESUMEN Introducción: El uso de órtesis de tobillo reduce el riesgo de lesiones en el tobillo en jugadores de baloncesto. Sin embargo, los mecanismos de protección de lesión proporcionados por las órtesis durante el juego de baloncesto aún son desconocidos. Objetivos: Analizar el efecto del uso de órtesis de tobillo lace-up (con cordón) y de un protocolo de ejercicio que simuló la intensidad del juego de baloncesto sobre la fuerza de reacción del suelo (FRS) durante saltos verticales específicos del baloncesto. Métodos: Once jugadores de baloncesto del sexo masculino con menos de 18 años realizaron 48 saltos verticales, con y sin órtesis de tobillo, durante un protocolo de ejercicios compuesto por cuatro períodos de 10 minutos, que simularon el perfil de actividad e intensidad del juego de baloncesto, así como los intervalos típicos entre los períodos. Las FRS mediolaterales (variables: mayores picos medial y lateral) y verticales (variables: pico vertical, pico de impulso, impulso en 50 ms de aterrizaje, tasa de sobrecarga y altura del salto) fueron medidas durante las fases de despegue y aterrizaje de todos saltos realizados en el protocolo de ejercicio. Resultados: El uso de órtesis redujo la FRS mediolateral en todos los períodos analizados, durante las fases de despegue y aterrizaje (P < 0,05), sin afectar la FRS vertical (P > 0,05). La FRS mediolateral y vertical (picos mediolateral y vertical de despegue, picos mediolaterales de aterrizaje, pico de impulso de aterrizaje, tasa de sobrecarga en el despegue y aterrizaje) aumentaron significativamente durante cuatro períodos subsiguientes de 10 minutos (P < 0,05). Sin embargo, para la FRS mediolateral, el aumento a lo largo del tiempo fue mayor sin el uso de órtesis. Conclusiones: El uso de órtesis de tobillo redujo la FRS mediolateral en el miembro inferior, mientras que hubo un aumento progresivo de la carga externa aplicada al cuerpo durante los saltos en los períodos subsiguientes del protocolo de ejercicios con la misma intensidad del juego de baloncesto. Nivel de evidencia I; Ensayo clínico aleatorizado.

RESUMO Introdução: O uso de órtese de tornozelo reduz o risco de lesões no tornozelo em jogadores de basquetebol. No entanto, os mecanismos de proteção de lesão fornecidos pelas órteses durante o jogo de basquetebol ainda são desconhecidos. Objetivos: Analisar o efeito do uso de órtese de tornozelo lace-up (com cordão) e de um protocolo de exercício que simulou a intensidade do jogo de basquetebol sobre a força de reação do solo (FRS) durante saltos verticais específicos do basquetebol. Métodos: Onze jogadores de basquetebol do sexo masculino com menos de 18 anos realizaram 48 saltos verticais, com e sem órtese de tornozelo, durante um protocolo de exercícios composto por quatro períodos de 10 minutos, que simularam o perfil de atividade e intensidade do jogo de basquetebol, assim como os intervalos típicos entre os períodos. As FRSs mediolaterais (variáveis: maiores picos medial e lateral) e verticais (variáveis: pico vertical, pico de impulso, impulso em 50 ms da aterrissagem, taxa de sobrecarga e altura do salto) foram medidas durante as fases de decolagem e aterrissagem de todos os saltos realizados no protocolo de exercício. Resultados: O uso de órtese reduziu a FRS mediolateral em todos os períodos analisados, durante as fases de decolagem e aterrissagem (P < 0,05), sem afetar a FRS vertical (P > 0,05). A FRS mediolateral e vertical (picos mediolateral e vertical de decolagem, picos mediolaterais de aterrissagem, pico de impulso de aterrissagem, taxa de sobrecarga na decolagem e aterrissagem) aumentaram significativamente durante quatro períodos subsequentes de 10 minutos (P < 0,05). No entanto, para a FRS mediolateral, o aumento ao longo do tempo foi maior sem o uso de órtese. Conclusões: O uso de órtese de tornozelo reduziu a FRS mediolateral no membro inferior, enquanto houve um aumento progressivo da carga externa aplicada ao corpo durante os saltos nos períodos subsequentes do protocolo de exercícios com mesma intensidade do jogo de basquetebol.

Recent advancements in diagnostics and treatment of subtle syndesmotic injury / 国际外科学杂志

Patients with subtle syndesmotic injury, without fracture, have the symptoms similar to lateral ankle ligament injury, thus, leading to diagnostic error and misdiagnosis. Improper treatment often causes chronic pain and dysfunction, accelerating ankle degeneration. The diagnosis of subtle syndesmotic injury demands synthesis of examination results, among which arthroscopy is the gold standard. The treatment of subtle syndesmotic injury depends on the course of injury: conservative treatment, syndesmosis screw, button plate, elastic syndesmosis hook plate and mixed fixation are performed in acute injury. Arthroscopic debridement, syndesmosis fusion and ligament reconstruction are performed in chronic ones. In subacute ones, treatment is controversial. Early diagnosis and treatment of subtle syndesmotic injury play an important role in its prognosis. This article will review the recent advancements in diagnostics and treatment of subtle syndesmotic injury.

Clinical efficacy of sticking-needle acupuncture plus tendon-regulating manipulation in the treatment of acute ankle sprain / 针灸推拿医学（英文版）

Objective: To explore the treatment effect of sticking-needle acupuncture plus tendon-regulating manipulation on pain, swelling and joint dysfunction due to acute ankle sprain.Methods: A total of 80 patients with acute ankle sprain were recruited and divided into a control group and a treatment group according to the random number table method, with 40 patients in each group. Both groups received the same conventional interventions. The control group was treated with additional tendon-regulating manipulation, and the treatment group was treated with tendon-regulating manipulation plus sticking-needle acupuncture. The pain, swelling and joint dysfunction of the ankle were observed in both groups before and after 3 d, 7 d and 14 d of treatment. Results: Before treatment, there was no statistically significant difference in the visual analog scale (VAS) score of pain between the two groups (P>0.05). After treatment, the VAS scores of both groups showed a decreasing trend over time, and the differences within the groups were statistically significant (P<0.05). After 3 d, 7 d and 14 d of treatment, the VAS scores in the treatment group were lower than those in the control group, with statistically significant differences (P<0.05). Before treatment, there was no statistically significant difference in the degree of swelling between the two groups (P>0.05). After treatment, the degrees of swelling in both groups showed a decreasing trend over time, and the differences within the groups were statistically significant (P<0.05). After 3 d and 7 d of treatment, the degrees of swelling in the treatment group were lower than those in the control group, with statistically significant differences (P<0.05). There was no statistical difference in the degree of swelling between the two groups after 14 d of treatment (P>0.05). Before treatment, there was no statistically significant difference in the American Orthopedic Foot Ankle Society (AOFAS) ankle-hindfoot scale score between the two groups (P>0.05). After treatment, the AOFAS ankle-hindfoot scale scores of both groups showed an increasing trend over time, and all the differences within the groups were statistically significant (P<0.05). After 3 d, 7 d and 14 d of treatment, the AOFAS ankle-hindfoot scale scores in the treatment group were higher than those in the control group, with statistically significant differences (P<0.05). Conclusion: Based on the routine intervention, the addition of sticking-needle acupuncture and tendon-regulating manipulation was better in alleviating pain and swelling and improving joint function in patients with acute ankle sprain than the addition of tendon-regulating manipulation alone.

Epidemiology of injuries due to ankle sprain diagnosed in an orthopedic emergency room / Epidemiologia das lesões por entorse do tornozelo diagnosticadas em pronto atendimento de ortopedia

ABSTRACT Objective To use magnetic resonance imaging to assess the prevalence of foot and ankle ligament injuries and fractures associated with ankle sprain and not diagnosed by x-ray. Methods We included 180 consecutive patients with a history of ankle sprain, assessed at a primary care service in a 12-month period. Magnetic resonance imaging findings were recorded and described. Results Approximately 92% of patients had some type of injury shown on the magnetic resonance imaging. We found 379 ligament injuries, 9 osteochondral injuries, 19 tendinous injuries and 51 fractures. Only 14 magnetic resonance imaging tests (7.8%) did not show any sort of injury. We observed a positive relation between injuries of the lateral complex, syndesmosis and medial ligaments. However, there was a negative correlation between ankle ligament injuries and midfoot injuries. Conclusion There was a high rate of injuries secondary to ankle sprains. We found correlation between lateral ligament injuries and syndesmosis and deltoid injuries. We did not observe a relation between deltoid and syndesmosis injuries or between lateral ligamentous and subtalar injuries. Similarly, no relation was found between ankle and midfoot injuries.

Métodos Foram incluídos no estudo 180 pacientes consecutivos, com história de entorse do tornozelo, atendidos em um serviço de Atenção Primária no período de 12 meses. Os achados dos exames de ressonância magnética foram catalogados e descritos. Resultados Aproximadamente 92% dos pacientes apresentaram algum tipo de lesão na ressonância. Dentre as injúrias observadas, estavam 379 lesões ligamentares, 9 lesões osteocondrais, 19 lesões tendíneas e 51 fraturas. Apenas 14 ressonâncias magnéticas (7,8%) não mostraram qualquer tipo de lesão. Observamos relação positiva entre lesões do complexo lateral, sindesmose e medial. No entanto, houve correlação negativa entre lesões ligamentares do tornozelo e aquelas do mediopé. Conclusão Foi alta a ocorrência de lesões secundárias à entorse. Apontamos correlação entre as lesões ligamentares laterais com as sindesmodais e do deltoide. Não notamos relação entre as lesões do deltoide e da sindesmose, e nem entre as ligamentares laterais e a subtlalar. Também não foram observadas relações entre as lesões do tornozelo e as do mediopé.

Bilateral Talus and Navicular Fractures accompanied with Unilateral Calcaneal Fracture: A Case Report

@#An 18-year old male patient, with a history of paragliding accident, sustaining a coronal shear fracture of the body of the talus, an anterior process fracture of the calcaneus extending to the calcaneocuboid joint and a nondisplaced navicular body fracture at the right foot and a displaced fracture of the navicular body accompanied with posteromedial process fracture of the talus at the left side was referred to our emergency clinic. For the right foot, the coronal plane fracture of the talar body was anatomically reduced and fixed with screws. For the left foot, screw fixation was performed through the lateral aspect to fix the large posteromedial fragment. Small bone fragments were removed from the left navicular fracture, and the main fragments were also fixed with screw. The talo-navicular joint was stabilised with a Kirschner wire. At 36 months follow-up, bilateral foot and ankle functions were satisfactory, Maryland scores of the right and left foot were 85 (good) and 90 (excellent), respectively, and the patient regained his full activity level by the 5th month postoperatively. With reference to the number and types of fractures in this one patient, we present a standard protocol for treatment of isolated talus, navicular and calcaneal fractures presenting together in a single foot injury.

Observation on clinical efficacy of warm needling therapy for chronic lumbar strain / 针灸推拿医学（英文版）

Objective:To observe the clinical efficacy of warm needling therapy for chronic lumbar strain.Methods:A total of 60 patients with chronic lumbar strain who met the inclusion criteria were randomized into a treatment group and a control group by the random number table,with 30 cases in each group.The treatment group was treated with warm needling therapy,while the control group was treated with ordinary acupuncture treatment.The treatments were both performed once every other day,and 7 times constituted a course of treatment.Visual analog scale (VAS) score was used to assess the degree of pain and the clinical efficacy was compared between the two groups.Results:The total effective rate of the treatment group was higher than that of the control group (P＜0.05).There was no significant difference in VAS score between the two groups before treatment (P＞0.05).After treatment,the VAS scores of both groups decreased significantly,and the intra-group differences were statistically significant (both P＜0.05).The VAS score of the treatment group after treatment was statistically different from that in the control group (P＜0.05).Conclusion:Warm needling therapy has a better curative effect than ordinary acupuncture in the treatment of chronic lumbar strain.

Stress Radiographs under Anesthesia for Painful Chronic Lateral Ankle Instability / 대한족부족관절학회지

PURPOSE: Anterior drawer and varus stress radiographs are commonly to diagnose chronic lateral ankle instability. We compared the preoperative stress radiographs with the intraoperative radiographs under anesthesia to determine the accuracy and efficacy of stress radiographs in an outpatient clinical environment. MATERIALS AND METHODS: Data was collected from patients who underwent a modified Broström operation for painful chronic unilateral lateral ankle instability between January 2014 and June 2016. Subjects were divided into three groups—complete tear, partial tear, and instability without rupture—according to the status of preoperative MRI findings of the anterior talofibular ligament. The anterior drawer and varus stress radiographs were taken preoperatively and intraoperatively under anesthesia. RESULTS: Ninety-six patients, with a mean age of 29.63 years, were enrolled. There were 39, 46, and 11 patients in the complete tear, partial tear, and instability without rupture groups, respectively. On the anterior drawer and varus stress radiographs of the affected limb, talar anterior translation and varus tilting were significantly increased by 2.56 mm and 2.0°. The gaps between the unaffected limbs were also increased by 2.47 mm and 1.32° after anesthesia. Although the stress radiographs were taken under anesthesia, the results were often smaller than the diagnostic value. CONCLUSION: Stress radiographs for painful chronic lateral ankle instability taken at the outpatient clinic might be inaccurate for diagnosis.

Research progress of ankle sprains, protection and rehabilitation / 医用生物力学

Ankle sprains are one of the most common surgical injuries in clinic. In this article, the foot anatomy structure was elaborated, and the biomechanics of ankle ligaments during sports was mainly reviewed. At the same time, the mechanism of ankle sprains was analyzed, the principal means of ankle sprains, prevention and rehabilitation at present were summarized, and the use of ankle braces to prevent ankle sprains as well as its research progress were introduced emphatically. The classification and characteristics of ankle braces were then summarized, and the prevention of ankle sprains and development of ankle braces were prospected. The multiple ankle lateral ligament damage was due to the physiological structure differences between lateral and medial ligaments of the ankle joints, and such structure characteristic should be considered while improving ankle braces and designing new ankle braces. Wearing ankle braces plays a key role in ankle sprains protection, which can shorten the recovery time and avoid re-injury in clinical rehabilitation. For rehabilitation of severe ankle sprains, semi-rigid ankle braces are better than elastic ones.

A controlled study on treatment of acute lumbar sprain by acupuncture at Yaotongdian (EX-UE 7) plus tuina manipulation / 针灸推拿医学（英文版）

Objective:To observe the clinical effects of acupuncture at Yaotongdian (EX-UE 7) plus the oblique Ban-pulling manipulation for acute lumbar sprain. Methods:A total of 180 patients were divided into an observation group and a control group by drawing lots. The 98 cases in the observation group were treated by puncturing Yaotongdian (EX-UE 7) plus the oblique Ban-pulling manipulation. The 82 cases in the control group were only treated by the oblique Ban-pulling manipulation. After the two groups were treated continuously for three sessions, the therapeutic effects were observed. Results:In the observation group, 96 cases were cured and 2 cases were improved; the curative rate was 98.0% and the total effective rate was 100%. In the control group, 76 cases were cured, 4 cases were improved and 2 cases failed; the curative rate was 92.7% and the total effective rate was 97.6%. In comparison of the curative rate and total effective rate, the differences were not statistically significant (P>0.05). But, the curative rate after the first treatment was higher in the observation group than that in the control group, with a significant difference between the two groups (P<0.05). Conclusion:The therapeutic effects were similar by acupuncture at Yaotongdian (EX-UE 7) plus oblique Ban-pulling manipulation and by single oblique Ban-pulling manipulation for acute lumbar sprain. But, it took effect quickly by puncturing Yaotongdian (EX-UE 7) plus the oblique Ban-pulling manipulation.
