Presencia de cresta ósea en la epífisis proximal de la tibia: propuesta para su incorporación en la terminologia anatomica / Presence of a bony crest in the proximal epiphysis of the tibia: proposal for its incorporation in the terminologia anatomica

RESUMEN: La Terminologia Anatomica (TA) presenta las estructuras anatómicas en un lenguaje unificado para todas las estructuras del cuerpo humano. Sin embargo, hay características como algunos accidentes óseos que no se han considerado en las actualizaciones de la TA, ya sean epónimos que no se han relacionado con términos actuales o estructuras descritas clásicamente, como es el caso de una característica ósea que se observa y palpa fácilmente en la epífisis proximal de la tibia, a nivel del cóndilo lateral, uniendo el tubérculo anterolateral de la tibia con la tuberosidad de la misma. Esta característica corresponde a una elevación lineal, descrita como lugar de inserción del tracto iliotibial y del músculo tibial anterior. Basado en lo anterior, se analizaron 65 tibias de individuos Chilenos, adultos, de ambos sexos, 60 pertenecientes a la Universidad de La Frontera y 5 a la Universidad San Sebastián, considerando como criterio de inclusión la integridad del tejido compacto en la epífisis proximal. La revisión de las muestras reveló la presencia de una elevación lineal en el 100 % de los casos, uniendo la tuberosidad de la tibia con el tubérculo anterolateral (Gerdy), no observándose elevación similar desde la tuberosidad de la tibia en dirección al cóndilo medial. Esta elevación es utilizada como referencia en la palpación durante la evaluación de la rodilla. Por las evidencias presentadas, consideramos que esta elevación debe considerarse en la TA como una característica más de la tibia, en base a su disposición lineal y elevada, además de su dirección oblicua desde la tuberosidad de la tibia al tubérculo anterolateral de la misma, por lo que proponemos denominarla como cresta anterolateral de la tibia (Crista anterolateralis tibiae).

SUMMARY: Anatomical Terminology (AT) presents anatomical structures in a unified language for all structures of the human body. However, there are characteristics such as some bone accidents that have not been considered in the TA updates, whether they are eponyms that have not been related to current terms or classically described structures, as is the case of a characteristic bone that is easily observed and palpated in the proximal epiphysis of the tibia, at the level of the lateral condyle, joining the anterolateral tubercle of the tibia with the tuberosity of the tibia. This characteristic corresponds to a linear elevation, described as the insertion site of the iliotibial tract and the tibialis anterior muscle. Based on the above, 65 tibiae from Chilean individuals, adults, of both sexes, 60 belonging to the Universidad de La Frontera and 5 from the Universidad San Sebastián were analyzed, considering as an inclusion criterion the integrity of the compact tissue in the epiphysis proximal. The review of the samples revealed the presence of a linear elevation in 100 % of the cases, joining the tibial tuberosity with the anterolateral tubercle (Gerdy), not observing similar elevation from the tibial tuberosity in the direction of the medial condyle. This elevation is used as a reference for palpation during knee evaluation. Based on the evidence presented, we consider that this elevation should be considered in TA as one more characteristic of the tibia, based on its linear and elevated disposition, in addition to its oblique direction from the tibial tuberosity to the anterolateral tubercle of the tibia, for what we propose to call it the Crista anterolateralis tibiae (anterolateral crest of the tibia).

Effectiveness of tibialis posterior tendon transfer for foot drop secondary to peroneal nerve palsy / 中国修复重建外科杂志

Objective: To investigate the effectiveness of tibialis posterior tendon transfer for foot drop secondary to peroneal nerve palsy. Methods: The clinical data of 21 patients with unilateral foot drop secondary to peroneal nerve palsy between October 2009 and September 2016 was retrospectively analyzed. There were 12 males and 9 females with an average age of 32.1 years (range, 23-47 years). The causes of peroneal nerve injury were iatrogenic injury in 7 cases, tibiofibular fractures combined with compartment syndrome in 5 cases, nerve exploration surgery after stab or cut injury in 3 cases, direct violence in 4 cases, and the fibular head fracture in 2 cases. The average time from injury to operation was 5.6 years (range, 2-8 years). There was 1 case of hallux valgus and 5 cases of toe flexion contracture. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot scores, Foot and Ankle Ability Measure (FAAM) scores, range of motion (ROM), and dorsiflexion strength of ankle joint were used to evaluated the ankle function. Radiographic evaluation for the changes of postoperative foot alignment included Meary angle, calcaneal pitch angle, and hindfoot alignment angle. Results: All incisions healed by first intention. All patients were followed up 18-42 months (mean, 30.2 months). The dorsiflexion strength of ankle joint recovered from grade 0 to grade 3-4 after operation. There was no patient with a postoperative flat foot deformity and claw toe during follow-up. There was no significant difference in Meary angle, calcaneal pitch angle, and hindfoot alignment angle between pre- and post-operation ( P>0.05). The AOFAS score, FAAM score, and ROM of dorsiflexion significantly improved at last follow-up when compared with preoperative values ( P<0.05); while there was no significant difference in ROM of plantar-flexion between pre- and post-operation ( t=4.239, P=0.158). There were significant differences in AOFAS score, FAAM score, and ROM of dorsiflexion between affected and healthy sides ( P<0.05); but no significant difference in ROM of plantar-flexion was found ( t=2.319, P=0.538). Conclusion: Tibialis posterior tendon transfer is an effective surgical option for foot drop secondary to peroneal nerve palsy. And no postoperative flat foot deformity occurred at short-term follow-up.

Muscle activation pattern of gluteus medius, tibialis anterior and peroneus longus during drop landing on different surfaces: A cross-sectional study

BACKGROUND@#Gluteus medius (GMeds), peroneus longus (PL), and tibialis anterior (TA) help in maintaining frontal stability of the lower extremity, particularly, the ankle. Muscle activation must be sufficient to prevent the occurrence of an ankle sprain. The purpose of this study is to compare the muscle activation of the GMeds, TA, and PL during drop landing on stable and unstable surfaces of physically active individuals.@*METHODS@#Surface EMG (sEMG) was used to determine the muscle activation pattern of the GMeds, TA, and PL of fifteen (15) recreational athletes during drop landing. The mean percentage of maximum voluntary isometric contraction (%MVIC) was calculated for comparison. Wilcoxon signed-rank test was used to compare means.@*RESULTS@#There were no statistically significant differences in the muscle activity of GMeds (p=0.69), TA (p=0.26), and PL (p=0.23) on stable and unstable surfaces. However, a small effect size showed that GMeds (d=0.30) has higher activation in the unstable surface while TA (d=0.28) and PL (d=0.17) have lower activation on unstable surface.@*CONCLUSION@#Landing surface does not significantly alter muscle activity of GMeds, TA, and PL. However, the magnitude of the difference in the mean %MVIC between groups shows the compensatory mechanism of the body when subjected to different surface conditions. This can be used when creating injury prevention programs of the lower extremity.

Evaluating Electrical Activity of Tibialis Anterior Muscle and Balance in Hemiparetic Patients Following Central and Peripheral Electrical Stimulation - Protocol for a Randomized, Double-blinded, Clinical Trial

Concomitant transcranial direct current stimulation (tDCS) is suggested to enhance the functional effects of other physical rehabilitation methods in individuals with motor impairment stemming from a chronic cerebrovascular disease. Thus, the primary aim of the proposed study is to analyze the electrical activity of the tibialis anterior (TA) muscle of the paretic limb in stroke survivors following an intervention involving the combination of tDCS over the motor cortex and peripheral electrical stimulation (PES) administered over the paretic TA. The secondary objective is to analyze the effect on dynamic balance Methods: Thirty-six adult stroke survivors will be randomized into three groups: 1) Active tDCS+ active PES; 2) Sham tDCS + active PES and 3) Active tDCS + sham PES. TDCSactive will be positioned bilateral over the primary motor cortex of the damaged hemisphere (C1 or C2) and the cathode will be positioned over the primary motor cortex of the undamaged hemisphere (C1 or C2) with a current of 2 mA for 20 minutes. For sham tDCS, will follow the same standarts, however, the equipment will be switched on for only 20 seconds. PES will be administered to the paretic TA at 50 Hz for 30 minutes. Evaluations: the median frequency and root mean square (RMS) of the paretic TA will be analyzed using electromyography (EMG) and dynamic balance will be evaluated using the Mini-Balance Evaluation System (Mini-BESTest) at baseline (pre-intervention), after 10 treatment sessions at a frequency of five times a week for two weeks (post-intervention) and 30 days after the end of the interventions (follow up). Discussion:PES has proven to facilitate the conduction of sensory-motor afferences to the cerebral cortex in stroke survivors. Combining PES with tDCS, which has a direct effect on increasing cortical excitability, could favor motor acquisition and neuronal plasticity in this population

Surgical Repair of Tibialis Anterior Muscle Herniation Using a Synthetic Mesh That Was Beneath the Fascia after a Military Training Program: A Case Report

Tibialis anterior muscle herniation is the most common type of skeletal muscle herniation of the lower legs. The treatment of muscle herniation relies on the patient's symptoms. For patients with chronic large fascial defects, fascial grafting with synthetic mesh can be considered. In this case of a patient who was exposed to excessive strain on his lower legs during a military training program, the use of a secure repair technique with synthetic mesh was required. This paper presents a case of tibialis anterior muscle herniation that was treated successfully with a monofilament knitted polypropylene mesh covered by the tibialis anterior fascia. The advantages of this technique include early rehabilitation and an early return to work. No significant difference in the clinical results compared to other methods were observed and there were no complications. The military training program appeared to have aggravated the patient's symptoms of tibialis anterior muscle herniation. On the other hand, larger scale study will be needed to determine if this program actually affects the clinical outcomes.

Analysis of Contractile Properties in Gastrocnemius, Tibialis Anterior Muscle of Amateur Male Soccer Players Using Tensiomyography

BACKGROUND: Tensiomyography (TMG) is a relatively new technique that assesses the contractile properties of muscles in response to a single electrical stimulus. This study aimed to evaluate the contractile properties of the gastrocnemius and tibialis anterior (TA) muscles in amateur soccer players using TMG. METHODS: We recruited 41 male soccer players (high school group, n=21; college group, n=20). The gastrocnemius medialis (GM), gastrocnemius lateralis (GL), and TA muscles of both lower extremities were assessed using TMG. The maximal displacement (Dm), delay time, contraction time (Tc), sustained time, and half-relaxation time were obtained and compared between the two groups. RESULTS: First, both groups showed low Dm for the GM and TA muscles, which indicated high stiffness of the muscle tone. Second, the Tc and contraction velocity (Vc) were high for all muscles, except for the GL showing lower speed than the other muscles, which represented the sports-specific characteristics of the soccer players. Third, there were no significant differences in the measurement variables between the dominant and non-dominant sides, except for the Tc of the GM in high school athletes and Vc of the TA in college athletes. CONCLUSIONS: These results reflected the sports-specific needs and characteristics of soccer players. A risk of injury is associated with a high degree of stiffness, and various methods for preventing it should be considered.

Morphological variations and accessory ossicles in the peroneal and tibialis muscles / 대한해부학회지

This study describes five bilateral anatomical variations in the feet of a 97-year-old male cadaver. Following routine dissection, all variants were measured and documented. Three accessory tendons and two accessory ossicles were identified. Bilateral accessory tendons were present from the tibialis anterior (type II), peroneus tertius (type III), and peroneus brevis muscles. Accessory tendon length was 36–104 mm and width was 1–3 mm each inserting more distally then the main tendon. Accessory ossicles were identified as an accessory navicular and os peroneum, respectively. Individually, each variation has varying prevalence rates in the literature, but to date, no known studies have been published describing the combined presence of all five bilateral variations. The acknowledgement of multi-variant cases such as this one may be helpful in the clinical setting, particularly for patients with pathology or for those undergoing foot and ankle surgery.

Resumen: Las roturas del tendón tibial anterior son lesiones infrecuentes, con diversas etiologías, que pueden causar déficits significativos en la funcionalidad del tobillo, lesiones a veces diagnosticadas tardíamente, siendo muchas veces la alteración de la marcha el síntoma que hace acudir al paciente a consulta médica. Seis semanas van a marcar el límite entre la lesión aguda y la crónica, precisando distintos enfoques terapéuticos, junto con otros parámetros como la edad, demanda funcional o patologías concomitantes. Objetivo: Presentar dos casos de rotura aguda, con distinta etiología, la técnica quirúrgica empleada y los resultados finales. Material y métodos: presentamos dos casos de rotura aguda del tendón tibial anterior en su zona crítica hipovascular, un varón y una mujer, con etiología postraumática y espontánea respectivamente, en las cuales se realizó reinserción tendinosa en el escafoides tarsiano con un tornillo de biotenodesis, seguido de una inmovilización con autorización de marcha a las tres semanas y posterior fisioterapia. Resultados: En ambos casos se obtuvo un resultado funcional satisfactorio, con una mejoría importante en la puntuación AOFAS, reincorporándose a sus actividades laborales y deportivas a los 3 y 4 meses de la cirugía, respectivamente, con un seguimiento de 7.5 años y 10 meses. Discusión: Esta técnica, dentro de la variedad descrita en la literatura, nos ha proporcionado excelentes resultados, restaurando la funcionalidad del tendón tibial anterior y mostrándose reproducible por su sencillez, proporcionando un alto grado de seguridad a la hora de realizar una fisioterapia precoz.

Abstract: Tibialis anterior tendon rupture is a relatively rare injury, with diverse etiologies, that can cause significant deficits in the functionality of the ankle. These injuries are sometimes diagnosed too late, being in many occasions the alteration in walking the symptom that makes the patient go to the doctor. The six weeks will mark the limit between acute and chronic injury, requiring different therapeutic approaches, along with other parameters such as age, functional demand or concomitant pathologies. Objective: To present two cases of acute rupture, with different etiology, the surgical technique used and the final results. Material and methods: We present two cases of acute rupture of the tibialis anterior tendon in the critical hipovascular area, a male and a female, with posttraumatic and spontaneous etiology, respectively, in which tendon reinsertion was performed on the tarsal scaphoid with a biothenodesis screw, followed by immobilization with permission to walk at three weeks and subsequent physiotherapy. Results: In both cases a satisfactory final functional result was obtained, with a significant improvement in the AOFAS score, returning to their work and sports activities at 3 and 4 months of surgery respectively, with a follow-up of 7.5 years and 10 months. Discussion: This technique, within the variety described in the medical literature, has provided us excellent results, restoring the functionality of the anterior tibialis tendon and being reproducible for its simplicity, providing a high degree of safety when performing an early physiotherapy.

A Irreducible Ankle Fracture and Dislocation Due to Injured Tibialis Posterior Tendon Interposition: A Case Report / 대한족부족관절학회지

Fractures and fracture-dislocations of the ankle are caused by a variety of mechanisms. In addition to fractures, injuries of soft tissue, such as ligaments, tendons, nerves, and muscles may also occur. Among these, a tibialis posterior tendon injury is difficult to be identified due to swelling and pain at the fracture site. It is difficult to observe tibialis posterior tendon injury on a simple radiograph; it is usually found during surgery by accident. There are some studies regarding irreducible ankle fracture-dislocations due to interposition of the tibialis posterior tendon; however, to the best of our knowledge, there has not been any report about interposition of injured tibialis posterior tendon. Herein, we report a case of an irreducible fracture-dislocation of the ankle due to injured tibialis posterior tendon interposition that was observed intraoperatively, interrupting the reduction of ankle fracture-dislocation. We obtained satisfactory clinical result after reduction of the trapped tendon, fracture reduction, and internal fixation; therefore, we are willing to report this case with the consent of the patient. This study was conducted with an approval from the local Institutional Ethics Review Board.

Therapeutic Observation of Electroacupuncture at Extensors plus Acupoints Based on Syndrome Differentiation for Wrist-ankle Activity in Post-stroke Hemiplegia / 上海针灸杂志

Objective To observe the effect of electroacupuncture at extensors plus acupoints based on syndrome differentiation on the wrist-ankle activity in post-stroke hemiplegia. Method A total of 168 patients with post-stroke hemiplegia were randomly divided into a control group and a treatment group, 84 cases each. Both groups were prescribed with Western medication, based on which, the control group received electroacupuncture at acupoints based on syndrome differentiation, and the treatment group received electroacupuncture at extensors plus acupoints based on syndrome differentiation. The changes of electromyography (EMG) in the two groups after the intervention were observed, and the clinical efficacies were compared between the two groups.Results The total effective rate was 95.1% in the treatment group versus 91.0% in the control group, and the between-group difference was statistically significant (P0.05), but the intra-group differences were statistically significant in both groups(P0.05).Conclusion Electroacupuncture at extensors plus acupoints based on syndrome differentiation can increase the motor unit of carpi radialis and decrease the spasm of gastrocnemius in post-stroke hemiplegia, and consequently produce a remarkable clinical efficacy.

Efeitos do kinesio taping na dinâmica articular durante a marcha de pacientes após acidente vascular encefálico / Effects of kinesio taping in joint dynamics during gait in patients after stroke

Objetivo: Analisar os efeitos do kinesio taping® na dinâmica articular durante a marcha de pacientes hemiparéticos após acidente vascular encefálico (AVE). Métodos: Foi realizado um ensaio piloto com 14 participantes pós-AVE, alocados nos grupos intervenção (n = 7) e sham (n = 7). Foram analisados os ângulos articulares do tornozelo, joelho e quadril, durante as fases de balanço inicial e médio e contato inicial da marcha, antes da aplicação do taping e 24 horas após. A satisfação do paciente também foi analisada. Resultados: Não houve diferença entre os grupos nas angulações do tornozelo [balanço inicial (DM = -0,47º, IC95% -14,37 a 13,42); balanço médio (DM = -1º, IC 95% -14 a 12); contato inicial (DM = 1,22º, IC 95% -11,5 a 13,97)]; joelho [balanço inicial (DM = 5,66º, IC 95% -12,27 a 23,58); balanço médio (DM = -1,94º, IC 95% 23,6 a -19,76)]; quadril [balanço inicial (DM = 1,97º, IC 95% -6,98 a 3,03); balanço médio (DM = 0,68º, IC 95% -7,57 a 8,9); contato inicial (DM = 0º, IC 95% - 3,7 a 3,6)]. O grupo intervenção apresentou 10,5 vezes mais chances (OR = 10,5, IC 95% 0,4 a 267,1) de observar diferença quando o taping é aplicado em comparação ao grupo sham. Conclusão: Não houve diferença nas angulações do tornozelo, joelho e quadril durante a marcha, 24 horas após a aplicação do kinesio taping® em pacientes hemiparéticos. (AU)

Objective: To analyze the effects of Kinesio taping® in the joint dynamics during gait in hemiparetic patients after stroke. Methods: We conducted a pilot study with 14 participants after stroke allocated into intervention group (n = 7) and sham group (n = 7). We measured the joint angles of ankle, knee and hip during gait analysis at initial swing, mid swing and initial contact, without the application of taping and 24 hours after application. We also evaluated the patient's experience. Results: There was no difference between groups in the ankle angles [initial swing (DM = -0.47º, 95% CI -14.37 to 13.42); mid swing (DM = -1º, 95% CI -14 to 12); initial contact (DM = -1.22º, 95% CI -11.5 to 13.97)]; knee [initial swing (DM = 5.66º, 95% CI -12.27 to 23.58); mid swing (DM = -1.94º, 95%CI -19.76 to 23.6)]; hip [initial swing (DM = 1.97º, 95%CI -6.98 to 3.03); mid swing (DM = 0.68º, 95%CI -7.57 to 8.9); initial contact (DM = 0°, 95% -3.7 to 3.6)]. The chance to observe the difference when the taping is applied was 10.5 times higher (OR = 10.5, 95%CI 0.4 a 267.1) in the intervention group. Conclusion: There was no significant difference in angles of ankle, knee and hip during gait, 24 hours after Kinesio Taping® application in hemiparetic patients. (AU)

A Comparative Study of Clinical Outcomes and Second-Look Arthroscopic Findings between Remnant-Preserving Tibialis Tendon Allograft and Hamstring Tendon Autograft in Anterior Cruciate Ligament Reconstruction: Matched-Pair Design

BACKGROUND: This study aimed to compare stability, functional outcome, and second-look arthroscopic findings after anterior cruciate ligament reconstruction between remnant-preserving tibialis tendon allograft and remnant-sacrificing hamstring tendon autograft. METHODS: We matched two groups (remnant-preserving tibialis tendon allograft group and hamstring tendon autograft group) in terms of demographic characteristics, associated injury, and knee characteristics. Each group consisted of 25 patients. RESULTS: Operation time was longer in the remnant-preserving tibialis tendon allograft group, but there was no significant intergroup difference in stability, clinical outcome, and second-look arthroscopic findings. CONCLUSIONS: When an autograft is not feasible in anterior cruciate ligament reconstruction, the remnant-preserving technique can produce comparable results in terms of restoration of function, stability of the knee, and degree of synovium coverage at second-look arthroscopy compared to remnant-sacrificing hamstring autograft.

Tabialis Anterior Muscle Contraction On Driver’s Knee Angle Posture Less Than 101º For Foot Pressing And Releasing An Automotive Pedal

Proper driving requires a proper posture to bring comfort to drivers. A problem that commonly exists in driving is incorrect driving posture which can cause discomfort to the driver, especially when interacting with automotive pedals. Research on contraction of tibialis anterior (TA) muscle on driver's posture based on the knee angle less than 101º in a position of pressing and releasing a pedal was conducted to investigate and overcome this problem. This is a field experiment study and surface electromyography (sEMG) is used in collecting data on the TA muscle. The procedure of collecting data on the TA muscle before and after experiments follows the Surface ElectroMyoGraphy for the Non-Invasive Assessment of Muscles (SENIAM) recommendations. The result of the experiment shows that there is a strong negative relationship between driver's postures in nature based on the angle of the knee with TA muscle contractions, where the Pearson correlation coefficient (r) is - .993. While the temporal analysis measurements based on Maximum Voluntary Isometric Contraction (MVIC) 60% in a position of releasing a pedal exceeding rms µV 39.38, are 39.71 and 40.25 respectively. On the other hand, MVIC 2% rms µV values: 1.19 and 1.2 are obtained in the position of pressing the pedal. The knee angle with TA muscle contractions is significant [F (1, 10) = 660, p<.05] contributing 98.5% variance (R2 = .985) in the driver's posture. A linear equations model has been developed to clearly illustrate the result. In conclusion, when the knee angle of the driver's posture is increased, the TA muscle contraction is decreased. The increase in the knee angle will directly provide comfort to the driver while interacting with the pedal; and this is due to the reduction of TA muscle contractions.

Traumatic Myiasis Caused by an Association of Sarcophaga tibialis (Diptera: Sarcophagidae) and Lucilia sericata (Diptera: Calliphoridae) in a Domestic Cat in Italy

We describe here a rare case of traumatic myiasis occurred in August 2014, caused by an association of 2 Diptera species, Sarcophaga tibialis Macquart (Diptera: Sarcophagidae) and Lucilia sericata (Meigen) (Diptera: Calliphoridae), in a domestic cat in northern Italy. Species identification was based on adult male morphology. The present case is the first report of S. tibialis as an agent of myiasis in Italy, and also the first ever report of myiasis caused by an association of S. tibialis and L. sericata. The cat developed an extensive traumatic myiasis in a large wound on the rump, which was treated pharmacologically and surgically. The biology, ecology, and distribution of S. tibialis and L. sericata are also discussed. A literature review is provided on cases of myiasis caused by S. tibialis, and cases of myiasis by L. sericata involving cats worldwide and humans and animals in Italy.

Accuracy of Needle Placement in Cadavers: Non-Guided Versus Ultrasound-Guided

OBJECTIVE: To compare the accuracy rates of non-guided vs. ultrasound-guided needle placement in four lower limb muscles (tibialis posterior, peroneus longus, and short and long heads of the biceps femoris). METHODS: Two electromyographers examined the four muscles in each of eight lower limbs from four fresh frozen cadavers. Each electromyographer injected an assigned dye into each targeted muscle in a lower limb twice (once without guidance, another under ultrasound guidance). Therefore, four injections were done in each muscle of one lower limb. All injections were performed by two electromyographers using 18 gauge 1.5 inch or 24 gauge 2.4 inch needles to place 0.5 mL of colored acryl solution into the target muscles. The third person was blinded to the injection technique and dissected the lower limbs and determined injection accuracy. RESULTS: A 71.9% accuracy rate was achieved by blind needle placement vs. 96.9% accuracy with ultrasound-guided needle placement (p=0.001). Blind needle placement accuracy ranged from 50% to 93.8%. CONCLUSION: Ultrasound guidance produced superior accuracy compared with that of blind needle placement in most muscles. Clinicians should consider ultrasound guidance to optimize needle placement in these muscles, particularly the tibialis posterior.

Failure of Reduction for Ankle Fracture-Dislocation Caused by Tibialis Posterior Tendon Interposition: A Case Report / 대한족부족관절학회지

Fracture and fracture-dislocation of the ankle may be caused by a variety of mechanisms. In addition to the fracture, injury of soft tissue such as ligaments, tendons, nerves, and muscles may occur. Among these, tibialis posterior tendon injury is difficult to identify due to swelling and pain at the fracture site. There is no clear finding in radiological examination, therefore, it is found during surgery. In this case, irreducible fracture-dislocation of the ankle due to tibialis posterior tendon interposition was observed after the primary operation. The authors obtained satisfactory results in performance of a secondary operation assisted with arthroscopy.

BILATERAL VARIATIONS IN TENDONS OF DORSUM OF FOOT.

Anterior or extensor muscles of foot comprises Peroneus tertius (PT), Extensor digitorum longus (EDL), Extensor hallucis longus (EHL) and Tibialis anterior (TA). Presence of PT in many of the primates and humans suggests terrestrial bipedalism. PT is a dorsi-flexor of ankle joint and a weak evertor of foot. TA is the most medial and superficial dorsiflexor. Standard text-books describe the course of tendon of TA as passing deep to inferior extensor retinaculum (IER). In the present study, absence of PT with a course of TA superficial to IER on one side with variant origin of PT from Extensor digitorum longus on the other side were observed in an adult female cadaver. Knowledge on variations in PT and TA are of clinical significance and academic importance to orthopedic surgeons, radiologists and anatomists.

The effect of intermittent cryotherapy on the activities of citrate synthase and lactate dehydrogenase in regenerating skeletal muscle

This study examined the effect of three sessions of cryotherapy (three sessions of 30 minutes applied each 2 h) and muscle compression in the regenerating skeletal muscle of the rats. The middle belly of tibialis anterior muscle was injured by a frozen iron bar and received one of the following intervention: injury + cryotherapy (treated with cryotherapy); injury + placebo (sand pack), and injury (I).The enzymatic activities of citrate synthase (CS) and lactate dehydrogenase (LDH) were measured in the presence of 1mM or 10mM pyruvate. The ANOVA and Tukey's test (p<0.05) were performed for the statistical analysis. In summary, the intermittent sessions of cryotherapy, associated to muscle compression and applied immediately after the primary muscle injury minimized the CS and LDH activity at 4h30 and 24h periods post-lesion, which could be related to the reduction in the secondary muscle injury inherent to cryotherapy treatment.

Bilateral Tibialis Anterior Muscle Herniation / 대한피부과학회지

Muscle herniation is defined as a protrusion of a portion of a muscle through a defect of the muscle fascia. The anterior tibialis muscle is the most common site of herniation. This condition is a relatively common complaint among athletes, and it has been frequently reported in the orthopedic surgery literature, whereas it has received little attention in the dermatological literature. Clinical findings include the presence of soft, compressible nodules that vary in size depending on their position. Usually, herniation is asymptomatic and the main concern is cosmetic, but the patient may seek medical treatment because of pain. Here we report a 65-year-old woman who visited our hospital for an evaluation of two asymptomatic nodules that were on her lower legs, and was diagnosed with bilateral tibialis anterior muscle herniation.

Relationship between the Synovialization and the Clinical Results after Anterior Cruciate Ligament Reconstruction Using Tibialis Tendon Allograft / 대한스포츠의학회지

The purpose of this study was to evaluate the relationship between the second-look arthroscopic findings of synovialization and the clinical results after the arthroscopic anterior cruciate ligament (ACL) reconstruction with the fresh-frozen tibialis tendon allograft. Fifty-seven patients could be examined with the second-look arthroscopy after the ACL reconstruction with tibialis tendon allograft. The average duration from reconstruction to second-look arthroscopy was 18.4 months (range, 4-48 months). The patients were classified, according to the extent of synovialization, into 3 groups; 37 cases (64.9%) in group A (good), 15 cases (26.3%) in group B (partial), and 5 cases (8.8%) in group C (poor). The clinical results were compared in each group. The 2000 International Knee Documentation Committee (IKDC) subjective knee score was 80 or more in 31 cases (83.8%) in group A, 9 (60%) in group B, and 1 (20%) in group C respectively. All thirty seven cases (100%) in group A had negative or 1+firm end-point Lachman test and negative pivot shift test, however, only 2 cases (40%) in group C. KT-1000 arthrometer measurement was less than 5 mm in 37 (100%) in group A, 14 (93.3%) in group B, and 2 (40%) in group C. According to the 2000 IKDC knee examination form, 37 (100%) in group A, 14 (93.3%) in group B, and 2 (40%) in group C respectively were normal or nearly normal. The synovialization of the graft had positive correlation with the clinical results after the ACL reconstruction with fresh-frozen allograft.
