Reconstruction of anterior talofibular ligament and calcaneofibular ligament with autologous peroneus brevis tendon in the treatment of chronic lateral ankle instability / 中国骨伤

OBJECTIVE@#To explore the clinical efficacy of reconstruction the anterior talofibular ligament and calcaneofibular ligament with autologous peroneus brevis tendon for the treatment of chronic lateral ankle instability.@*METHODS@#The clinical data of 42 patients with chronic lateral ankle instability treated by anatomical reconstruction of anterior talofibular ligament and calcaneofibular ligament with autologous peroneus brevis tendon from July 2016 to July 2019 was retrospectively analyzed. Including 30 males and 12 females, age ranged from 25 to 46 years old with an average of (37.6±12.4) years. There were 15 cases of left foot and 27 cases of right foot, the time from injury to operation was 3 to 12 months with a mean of (7.4±2.8) months. And 14 patients had tenderness in lateral collateral ligament area, 28 patients complained of multiple ankle sprains while walking on the flat ground. At 12 months after operation, the talar tilt angle and visual analogue scale(VAS)were observed, ankle joint varus stress and anterior drawer test were performed to check the mechanical stability of the ankle joint, American Orhopaedic Foot and Ankle Society(AOFAS) was used to score the ankle and hindfoot functions and evaluate the curative effect.@*RESULTS@#Forty patients were followed up for 12 to 48 months with an average of (28.3±10.0) months, 2 cases were lost. The VAS decreased from(4.50±0.93) scores before surgery to (1.10±0.30) scores at 12 months after surgery;the talar tilt angle was reduced from (12.26±1.13)° before operation to (4.60±0.45)° at 12 months after operation;the AOFAS score increased from (65.10±7.50)scores before surgery to (84.40±3.95) scores at 12 months after surgery;all the differences were statically significant(P<0.05). According to the AOFAS score, 27 cases got excellent results, 7 good, 5 fair, and 1 poor. One patient had the symptoms of sural nerve injury after operation, and the symptoms were relieved after oral Mecobalamin for 3 months. The remaining patients had no complications such as nerve injury, infection, and skin necrosis. There was no instability of ankle joint, and both ankle varus stress test and drawer test were negative.@*CONCLUSION@#Autologous peroneal brevis tendon with double bone channel pass through the tendon (modified Chrisman-Snook operation) can anatomically reconstruct the anterior talofibular ligament and the calcaneofibular ligament, restore the stability of the patient's ankle joint, reduce postoperative complications, and restore ankle joint function well.

Anatomical study on reconstruction of calcaneus fibula ligament / 中国骨伤

OBJECTIVE@#To measure anatomical data of calcaneofibular ligament (CFL), relevant data of CFL attachment to provide an anatomical basis for CFL reconstruction.@*METHODS@#Twenty-seven adult ankle specimens were selected, including 11 males and 16 females, aged from 22 to 71 years old with an average of (41.6±17.2) years old;9 cases on the left side and 18 cases on the right side. The specimens reserved at least 20 cm above ankle joint and a complete foot, and exclude deformities, fractures, incomplete development and degenerative lesions. CFL was performed detailed anatomical observation, morphological parameters of CFL was measured, and coordinates of fibula side and calcaneal side of CFL in the coordinate axis were measured. The distance between fibula insertion of CFL and fibula tip, distance between calcaneal insertion of CFL and lateral calcaneal nodule, and Angle between CFL and long axis of fibula were also measured.@*RESULTS@#In these 27 specimens, CFL cases were all single bundles and the length of CFL was (32.83 ± 8.19) mm. The center point of fibula attachment in CFL was(2.87± 1.21) mm proximal with a coefficient of variation of 42.16% and (2.08±1.34) mm anteriorly with a coefficient of variation of 64.42%. The center point of calcaneal attachment region of CFL was located on coordinate axis on the distal end (15.32±5.33) mm, with a coefficient of variation of 34.79%, and the posterior part (6.38±2.15) mm, with a coefficient of variation of 33.86%. The distance between center point of fibula attachment and fibula tip was (4.81±0.82) mm. The distance between center point of calcaneal attachment area of CFL and lateral calcaneal nodules was(17.25±3.12) mm. Angle between CFL and fibula axis is (43 ±18)° .@*CONCLUSION@#According to anatomical studies, we could locate the fibula and calcaneal attachment of CFL by anatomical markers around ankle joint. However, the location of CFL attachment has a large variation, and the anatomical characteristics need to be considered in anatomical reconstruction.

Anatomical reconstruction of lateral ligament complex with singletunnel pullout stutrue fixation for chronic lateral ankle instability / 中国骨伤

OBJECTIVE@#To explore clinical effects of single-tunnel pullout structure fixation and anatomical reconstruction of lateral ligament complex in treating chronic lateral ankle instability.@*METHODS@#From January 2016 to December 2018, clinical data of 23 patients with chronic lateral malleolus instability who underwent anatomical reconstruction of lateral malleolus ligament complex with single-tunnel pullout structure fixation, were retrospectively studied. Among them, including 7 males and 16 females, aged from 17 to 33 years old with an avergae of (26.0±4.3) years old;16 patients classified to grage 0, and 7 patients classified to gradeⅠaccording to Kellgren-Lawrence(K-L) grading;the time of sprain ranged form 2 to 15 with an average of (5.7±2.9) times;the time from injury to operation ranged to 4 to 18 months with an average of (9.0±3.3) months. The range of movement of operative and uninjured ankle joints were measured at 24 months after opertaion, visual analogue scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) were used to evaluate ankle joint function and improvement of pain, K-L grading and MRI scoring of osteoarthritis of ankle (MSOA) were used to evaluate degree of cartilage degeneration of ankle joint.@*RESULTS@#All patients were followed up from 24 to 48 months with an average of (33.4±6.7) months. All the anterior talofibular ligaments and calcaneofibular ligaments were dissected and reconstructed by single-tunnel pullout structure fixation. The range of motion of dorsiflexion, plantarflexion, varus, and valgus on the operative side of ankle joint were smaller than those on the healthy side. There were no statistically differences in dorsiflexion and eversion between operative side and healthy side of ankle joint (@*CONCLUSION@#Treatment of chronic lateral ankle instability with reconstruction of lateral ligament complex with single-tunnel pullout structure fixation could provide better tendon and bone healing conditions, improve surgical safety and could achieve satisfactory clinical outcomes.

Mid-to-long term outcomes and influence factors of postoperative concurrent chronic ankle instability and posterior ankle impingement / 北京大学学报(医学版)

OBJECTIVE@#To investigate the mid-to-long-term efficacy of patients with chronic ankle instability combined with posterior impingement syndrome after 3-9 years of follow-up, and to analyze the influencing factors.@*METHODS@#From February 2010 to December 2015, 46 patients underwent concurrent lateral ankle ligament repair with posterior ankle arthroscopic surgery at the Institute of Sports Medicine, Peking University Third Hospital. The patient was first placed in a prone position and underwent arthroscopic debridement for the posterior impingement. After finishing the posterior arthroscopy, the surgeon and assistants first translated the patient to the affected side, then turned to the healthy side, and changed the position to the supine position. During the turning over, another assistant held the arthroscope and the instrument to ensure that it was sterile and could be used without replacement. The anterior ankle arthroscopy was operated if necessary and the lateral ankle ligament repair was anatomic repaired with anchors. The 42 patients were followed up, including 26 males and 16 females. The average age was (28.9±10.0) years. The patient's clinical symptoms, joint stability, mobility and motor function were compared by questionnaire and physical examination. The preoperative and postoperative visual analogue scale (VAS) scores, American Orthopaedic Foot and Ankle Society (AOFAS) scores, Tegner scores were compared, and the clinical scores and the patient age, gender, height and weight were compared. The correlations between body mass index (BMI), preoperative duration, surgery duration, and cartilage injury were analyzed.@*RESULTS@#The mean follow-up time was (71.8±22.8) months. The postoperative VAS scores (1.0 vs. 5.0, P<0.001), AOFAS scores (92 vs. 80, P<0.001), and Tegner scores (6.5 vs. 2, P<0.001) were significantly superior to the preoperative levels. The excellent and good rate was 97.6%. The postoperative VAS score (t=2.719, P=0.10), AOFAS score (t=-2.853, P=0.10), Tegner score (t=-3.443, P=0.001) and time to return exercise (t=2.814, P=0.008) were negatively correlated with the patient age, and the postoperative VAS score was negatively correlated with cartilage injury (Z=-2.195, P=0.028).@*CONCLUSION@#The mid-to-long-term clinical outcomes of the chronic ankle ligament instability combined with the posterior impingement were good. The age of the patients was negatively correlated with the clinical outcome. The combined cartilage injury could aggravate the postoperative pain.

Reparacion endoscopica del ligamento lateral a través de dos portales en inestabilidad cronica del tobillo / Endoscopic repair of the lateral ligament for chronic ankle instability

Objetivos: La lesión del complejo ligamentario lateral del tobillo es una de las lesiones más frecuentes relacionada al deporte.Generalmente, la lesión del ligamento lateral evoluciona favorablemente con el tratamiento médico y kinésico, sin embargo, lainestabilidad lateral crónica se desarrolla como secuela en casi el 30% de los pacientes.Numerosas técnicas de cirugía abierta y artroscópica han sido descriptas para tratar esta patología.Materiales y Métodos: Se trataron 22 pacientes; 18 varones y 4 mujeres, edad 17 a 42 años (media 28 años). Todos lospacientes presentaban una historia de inestabilidad funcional con más de tres esguinces de tobillo en los últimos dos años. Serealizó una artroscopía anterior del tobillo e todos los pacientes con el fin de tratar la enfermedad asociada y posteriormente serealizó una reparación “todo adentro” del ligamento lateral a través de dos portales (anteromedial y anterolateral) utilizando unasutura de anclaje sin nudos.Resultados: Las evaluaciones de los resultados clínicos se realizaron con un seguimiento promedio de 25 meses (R: 17-31).Los resultados globales se objetivaron por medio del score de la Asociación Americana de Pie y Tobilllo (AOFAS). La puntuaciónAOFAS mejoró de 63 puntos (rango 52-77) antes de la operación a 90 puntos (rango 73-100) al final del follow up.Ningún caso de recurrencia de la inestabilidad del tobillo se encontró en los casos presentados...

Objectives: One of the most frequent lesions related to the sports activity is the ankle lateral ligament complex lesion. Generally,this lesion resolves favorably with medical and kinesiologic treatment; however, chronic lateral instability develops as a sequela innearly 30% of patients. Several open and arthroscopic surgery techniques have been described to treat this pathology.Materials and methods: Twenty-two patients were treated, 18 males and four females, aged between 17 to 42 years (meanage 28). All patients presented a history of functional instability with over three ankle sprains in the last two years. An anteriorarthroscopy of the ankle was performed in all patients with the aim to treat the associated lesions, and following that, an “all –inside” repair of the lateral ligament was also performed through two portals (anteromedial and anterolateral) using a knotlesssuture anchor.Results: Assessment of clinical results was carried out with an average follow-up of 25 months (Range: 17-31).Global results were established by means of the AOFAS score (The Ankle and Foot American Association). The AOFAS scoreimproved from 63 points before surgery (range 52-77) to 90 points (range 73-100) at the end of follow-up.No case of recurrence of ankle instability was found in the cases presented...

Esguince grave del tobillo. Reparacion abierta primaria / Acute ankle sprain. Surgical treatment

Introducción: Aún se discute sobre el tratamiento idealde las lesiones graves del ligamento lateral externo (LLE)del tobillo. Si bien ya no se la considera una lesión menor, los defensores del tratamiento funcional temprano (no operatorio) son numerosos. La sutura directa reconstituye la anatomía, permite la rehabilitación inmediata, aun portando el yeso posoperatorio, y reduce los tiempos de inmovilización. Es un procedimiento quirúrgico rápido y con mínima morbilidad. Sobre la base de los criterios anatómicos, los hallazgos quirúrgicos y la restitución funcional obtenida, se justifica la reparación abierta primaria de las lesiones graves agudas del LLE del tobillo cuando la inestabilidad clínica y radiológica es manifiesta.Materiales y métodos: Entre marzo de 2006 y marzo de2007 se evaluaron 29 pacientes sometidos a tratamientoquirúrgico (24 varones y 5, mujeres), de entre 16 y 50años, con un seguimiento de 6 meses a 9 años. De acuerdo con los criterios propuestos, se operaron a aquellos que habían sufrido un esguince lateral grave (bostezo externo mayor de 15º), sin episodios previos, diagnosticados en el período agudo, con no más de dossemanas de evolución. Se solicitaron radiografías simples y con estrés del tobillo y en 7 de ellos, resonancia magnética (RM). Se practicó la reparación por sutura directa de la lesión y en 6 pacientes se adicionaron anclajes óseos. Se confeccionó una grilla y se evaluó: dolor, movilidad, estabilidad, función, complicaciones y conformidad. Resultados: El dolor fue más común dentro del primer año. La flexoextensión activa se redujo 5º en promedio durante el primer año. En cuanto a la movilidad pasiva/estabilidad, un paciente quedó con un bostezo clínico sintomático e inestabilidad manifiesta (defecto técnico). Trece pacientes presentaron un pequeño bostezo residual asintomático. La rigidez subastragalina fue transitoria. En lo que se refiere a la función/marcha/práctica deportiva,un tercio de los pacientes no pudieron retoma...

Plicatura artroscópica del ligamento peroneo-astragalino anterior: una nueva técnica artroscópica / Arthroscopy plicature of the talo-fibular ligament: a new arthroscopic technique

Se presenta un método de plicatura artroscópica de tobillo en la lesión del ligamento peroneo- astragalino anterior (LPAA) haciendo énfasis en la necesidad de revisar las patologías intraarticulares que se asocian a dichas lesiones. El estudio incluye 16 casos; de estos se detectaron tres (18 por ciento) con patología intraarticular. Se llevó un seguimiento con una media de 23.8 meses (de 6 meses a 4 años) y solamente se encontró una recaída en uno solo de ellos (6.25 por ciento) lo que representa un 93.75 por ciento de éxitos lo cual se compara con la cirugía abierta que presenta una eficacia de 80 por ciento pero con una mayor morbilidad y lesionando mayor tejido sano, siendo el intervalo de confianza de 0.83 a 1, con una p < 0.05

Tratamento da instabilidade lateral crônica do tornozelo pela técnica de Broström modificada: utilizaçäo de âncoras metálicas / Treatmento of chronic lateral instability of the ankle by the Broström modified technique: utilization of anchor system

Os autores apresentam os resultados obtidos no tratamento de 9 pacientes (9 tornozelos) portadores de instabilidade lateral crônica do tornozelo. Os pacientes, todos ligados à prática de esportes, apresentaram idades de 18 a 45 anos (média de 27.3 anos) e distribuíram-se, quanto ao sexo, em 55.6 por cento do feminino e 44.4 do masculino. Quanto à lateralidade do acometimento, näo houve predominância. Foi constante o relato de torçöes prévias e instabilidade articular subjetiva. A indicaçäo dp tratamento cirúrgico através dessa técnica baseou-se na história e antecedentes, além do achado de subluxaçäo anterior e lateral do talo nas provas radiológicas de estresse de gaveta anterior e varo. A técnica cirúrgica aplicada tem como base o tensionamento das estruturas laterais através da plicatura e embricamento da cápsula articular onde permanecem os cotos ligamentares. A inclusäo do reforço regional pelo avanço do retináculo dos extensores trouxe segurança extra à reparaçäo. A utilizaçäo capsular anteriro para a aproximaçäo e fixaçäo da porçäo capsular anterior constitui auxílio importante na técnica, melhorando sua confiabilidade e reduzindo sua morbidade. Com a utilizaçäo desse método todos os pacientes avaliados foram reconduzidos aos parâmetros de normalidade quanto à estabilidade lateral do tornozelo e houve retorno integral às atividades pregressas em prazo näo superior a três meses após a intervençäo.
