Rotura aguda del tendón tibial anterior / Acute rupture of the tibialis anterior tendon

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.

Avulsion Fracture of Medial Cuneiform by Tibialis Anterior Tendon (A Case Report) / 대한족부족관절학회지

Avulsion fracture of medial cuneiform by tibialis anterior tendon is quite rare. It has been reported about the avulsion fracture and surgical repair of tibialis anterior tendon rupture at distal insertion site of medial cuneiform in Korea. We report a case of right foot medial cuneiform avulsion fracture by tibialis anterior tendon after autobike accident and describe this case with a review of literature.

Rotura del tendón tibial anterior / Tibialis anterior rupture

The tibialis anterior muscle is the main ankle extensor. Its tendon ruptures are very infrecuent, and there are only a few case reports about them in literature. Treatment in these patients must be tailored to their functional activity, being only those who are inactive candidates to orthopedic treatment. In most cases treatment is surgical, by termino-terminal repair, augmentation techniques with extensor hallucis longus (EHL) or tibialis anterior tendon allografting, among other techniques, depending mainly on the type of lesion and the time of evolution. In this case report we present a male 60 year old patient with End Stage Chronic Kidney Disease on Hemodialysis, who after a minor trauma in left foot while on plantar flexion presents acute pain in ankle’s medial aspect and step page gait. In the Emergency Department evaluation he was unable to stand in his heels, despite an adequate foot dorsiflexion. On Magnetic Resonance Imaging a rupture of the distal part of the tibialis anterior tendon was shown. Two weeks later a surgical termino-terminal repair with ethibond was performed, followed by 9 weeks of inmobilization and then rehabilitation. Twelve weeks after the surgical procedure the patient regain his normal activities, without gait limitation.

El músculo tibial anterior es el principal extensor del tobillo. Las roturas de su tendón son muy poco frecuentes y existen en la literatura sólo casos aislados que reportan su existencia. El tratamiento en estos pacientes debe basarse en la actividad funcional de estos, siendo sólo los pacientes inactivos candidatos al tratamiento ortopédico con órtesis. En la mayoría de los casos el tratamiento es quirúrgico, indicándose reparación término-terminal, técnicas de transferencia tendínea con extensor hallucis longus (EHL) o la utilización de aloinjerto entre otras técnicas, dependiendo del tipo de rotura y tiempo de evolución. En este reporte se relata el caso de un hombre de 60 años, con antecedentes de insuficiencia renal crónica, en diálisis, quien al sufrió un trauma menor en flexión plantar del pie izquierdo, presentó dolor agudo en la región medial del tobillo y posteriorincapacidad de extender el tobillo al realizar la marcha. Fue evaluado en el servicio de urgencia destacando la imposibilidad de mantenerse en talones, pese a tener una dorsiflexión adecuada al examen físico. Se solicitó una Resonancia Magnética (RM), donde se evidenció una rotura completa en la región distal del tendón tibial anterior. Se operó a las 2 semanas, realizándose una reparación término-terminal con sutura no reabsorbible. El post operatorio se manejó con inmovilización por 9 semanas y posterior rehabilitación. El paciente no presentó complicaciones, logrando reintegrarse a sus actividades laborales a las 12 semanas.

Clinical Outcomes after Arthroscopic ACL Reconstruction using Bone-Patellar Tendon-Bone Allografts, Anterior Tibialis Tendon Allografts, and Hamstring Tendon Autografts

PURPOSE: To use physical and quantitative tests and second look arthroscopy to compare knee joint stability, graft remodeling, and healing after arthroscopic anterior cruciate ligament (ACL) reconstruction in patients receiving bone-patellar tendon-bone (BPTB) allografts, tibialis anterior tendon (TA) allografts, and hamstring (HA) autografts. MATERIALS AND METHODS: We analyzed 338 patients who underwent ACL reconstruction between March 2000 and February 2006 and who were followed up for at least 1 year. There were 60 BPTB allografts, 153 TA allografts, and 125 HA autografts. We compared the range of motion (ROM), Lachman test, pivot shift test, KT-1000 arthrometer test, and International Knee Documentation Committee (IKDC) knee examination form among the three groups, as well as the laxity and synovial coverage of the grafts as determined by second look arthroscopy. RESULTS: There was no significant difference among the three groups with regard to preoperative and postoperative clinical and physical findings. Synovial coverage of greater than 50% was found in 60% of patients in the BPTB allograft group, in 69.2% of patients in the TA allograft group, and in 100% of patients in the HA autograft group. The HA autograft group had a higher incidence of synovial coverage greater than 50% (p=0.017, 0.025). Regarding IKDC grade, Grade A or B was found among 93.7% of the cases with synovial coverage greater than 50% and among 72.2% of the cases with synovial coverage less than 50%. There was a significant correlation between the extent of synovial coverage and the IKDC grade (p=0.015). CONCLUSION: The HA autograft group had superior synovial coverage over the other two groups on second look arthroscopy, and there was a significant correlation between the extent of synovial coverage and the IKDC grade.

Tibialis Anterior Tendon Transfer for Calcaneus Deformity in Children with Myelomeningocele: A Preliminary Report / 대한정형외과학회잡지

PURPOSE: To examine the results of tibialis anterior tendon transfer for the treatment of a calcaneus deformity in children with a myelomeningocele. MATERIALS AND METHODS: Twenty-seven feet in sixteen children were examined in this study. The mean age at the time of surgery was 7(+2) years (range, 4(+11)-14(+9)) and the mean follow up duration was 25 months (range, 15-50). Three-dimensional gait analysis and dynamic foot-pressure measurement were performed to analyze the results of the index operation. RESULTS: There was no recurrence or aggravation of the deformity. The sagittal kinematics of the ankle improved, and the relative impulse of the calcaneus decreased postoperatively. Those patients with an increased range of motion of the pelvic rotation during gait showed less improvement in the relative impulse of the calcaneus than those with a good range of pelvic rotation. They also had a lower range of knee sagittal motion and an increased range of abduction of the hip, and up-obliquity of the pelvis. CONCLUSION: A good range of motion of the hip and pelvis in coronal and transverse planes, and of the knee in the sagittal plane are important predictors of the functional transfer of tibialis anterior tendon in patients with a calcaneal gait in a myelomeningocele.
