Transferencia de trapecio inferior con injerto autólogo de semitendinoso y recto interno / Transfer of the lower trapezius muscle tendon augmented with semitendinosus and gracillis tendon

Existen múltiples opciones de tratamientos para las rupturas masivas irreparables posterosuperiores del manguito rotador. Describiremos la transferencia del trapecio inferior con aumentación utilizando semitendinoso y recto interno autólogos, bajo asistencia. De esta manera devolvemos el balance muscular y restablecemos las cuplas de fuerza para la correcta movilidad del hombro afectado. Esta técnica se realiza con dos incisiones y tres portales artroscópicos: la primera para la toma del recto interno y semitendinoso en la rodilla del mismo lado del hombro afectado (aumentación), y la segunda en la escápula para la toma del trapecio inferior y para el pasaje de los tendones al espacio subacromial y posterior fijación con anclas sin nudo

In massive irreparable posterosuperior rotator cuff ruptures, there are several options for treatment. We will describe the transfer of the lower trapezius muscle tendon augmented with semitendinosus and gracillis tendons autologous, under arthroscopic assistance. In this way, muscular balance is restored for correct shoulder mobility. This technique is performed with two incisions and three arthroscopic portals, the first for harvest of the gracillis and semitendinosus tendons, in the knee on the same side of the affected shoulder (augmentation) and the second in the scapula for the harvest of the lower trapezius muscle tendon, and for passage to the subacromial, and fixation with knotless anchors

Transferencias tendinosas en hombro. Técnica quirúrgica y revisión de la literatura / Tendon transfers in shoulder. Surgical technique and literature review

En lesiones con criterios de irreparabilidad del manguito rotador en pacientes jóvenes y activos se considera realizar transferencia tendinosa como una opción de tratamiento; transferencia del trapecio inferior en lesiones irreparables posterosuperiores del manguito rotador; transferencia del dorsal ancho vía anterior en lesiones irreparables de supraespinoso y transferencia de dorsal ancho en lesiones irreparables del subescapular. En este trabajo realizamos una revisión narrativa de la técnica quirúrgica. Además, se puede observar el video de la experiencia anatómica de cada técnica descripta

In rotator cuff injuries with irreparable criteria in active and young patients, tendon transfer is considered as a treatment option. We describe our experience in performing lower trapezius transfer in irreparable posterosuperior rotator cuff injuries, anterior latissimus dorsi transfer in supraspinatus injuries, and latissimus dorsi transfer in subscapularis injuries. We carry out a narrative review of the surgical technique with the subsequent video of the anatomical experience of each technique described

Triple transferencia tendinosa en la parálisis radial alta. A propósito de un caso / Triple tendinous transference in high radial paralysis. Apropos of a case

RESUMEN La parálisis del nervio radial producida por lesiones a nivel del brazo es considerada una parálisis alta, y se caracteriza por presentar la muñeca y los dedos flexionados y el pulgar en aducción con imposibilidad para la extensión de los mismos (muñeca y dedos). Todos los autores coinciden en que, para la extensión de la muñeca, el músculo de elección a transferir es el pronador redondo para el segundo radial. Sin embargo, hay diversidad de criterios sobre la utilización del palmar mayor o del cubital anterior para el extensor común de los dedos, y del palmar menor para el extensor largo del pulgar. Se presentó el caso de un paciente de 31 años de edad, con antecedente de accidente de tránsito y diagnóstico de parálisis radial alta de 18 meses de evolución, en el que se decide tratamiento quirúrgico utilizando el músculo cubital anterior después de una rehabilitación exitosa, obteniéndose excelentes resultados (AU).

ABSTRACT The radial nerve paralysis produced by lesions at the level of the arm is considered a high paralysis, and is characterized by presenting the wrist and fingers flexed and the thumb in adduction with impossibility of extending them (wrist and fingers). All consulted authors agree that, for wrist extension, the elective muscle to transfer is the round pronator for the second radial. However, there are different criteria on the use of the palmar major or anterior ulnar for the common finger extender, and the palmar minor for the long thumb extender. We presented the case of a 31-year-old patient, with a history of traffic accident and diagnosis of 18-month high radial paralysis, in which surgical treatment using the anterior ulnar muscle after a successful rehabilitation was decided, obtaining excellent results (AU).

RESUMEN Introducción: La ruptura espontánea del tendón de Aquiles es una afección frecuente en los pacientes jóvenes que practican deportes. Cuando no se realiza el diagnóstico inicial, pasa a ser una lesión crónica, donde su diagnóstico y tratamiento es aún más complejo. En la mayoría de estos casos son necesarios los injertos tendinosos. Objetivo: Demostrar la eficacia y resultados clínicos funcionales de la reparación quirúrgica de la ruptura crónica del tendón de Aquiles mediante transferencia del tendón peroneo lateral corto. Presentación del caso: Paciente masculino de 38 años de edad con antecedentes de una caída mientras practicaba deportes. Se constató ruptura crónica del tendón de Aquiles. Se realizó una cirugía a cielo abierto, con transferencia tendinosa del tendón peroneo lateral corto hacia el cabo distal del tendón de Aquiles. Se reforzó la plastia con el tendón del plantar delgado. Se colocó una inmovilización tipo bota para el tobillo con 30o de flexión plantar por seis semanas. Pasado este tiempo, se colocó una bota de marcha y comenzó la deambulación, así como la rehabilitación con apoyo parcial hasta cumplir tres meses. A los seis meses se incorporó a su vida normal con adecuada función del pie y el tobillo. Conclusiones: La reparación quirúrgica de la ruptura crónica del tendón de Aquiles mediante transferencia del tendón peroneo lateral corto constituye un método eficaz y ofrece buenos resultados clínicos y funcionales(AU)

ABSTRACT Introduction: Spontaneous rupture of the Achilles tendon is a frequent condition in young patients who practice sports. When the initial diagnosis is not made, it becomes a chronic injury, consequently, diagnosis and treatment is even more complex. In most of these cases, tendon grafts are necessary. Objective: To demonstrate the efficacy and functional clinical results of the surgical repair of the chronic rupture of the Achilles tendon by transferring the short lateral peroneal tendon. Case report: We report the case of a 38-year-old male patient with a history of a fall while playing sports. A chronic rupture of the Achilles tendon was found. Open surgery was performed, the short lateral peroneal tendon was transferred to the distal end of the Achilles tendon. The plasty was reinforced with the thin plantar tendon. Ankle boot-type immobilization was placed with 30° plantar flexion for six weeks. After this time, the patient received a walker boot, ambulation and rehabilitation began. The latter started with partial support during three months. At six months this patient returned to his normal life with adequate foot and ankle function. Conclusions: Surgical repair of chronic Achilles tendon rupture by transferring the short lateral peroneal tendon is an effective method and offers good clinical and functional results(AU)

Tratamento cirúrgico da instabilidade do ombro através da transferência do tendão longo do bíceps trans-subescapular / Surgical treatment of shoulder instability with trans-subscapularis transfer of the biceps long tendon

RESUMO O objetivo deste trabalho é descrever, em cadáver, a técnica de transferência do tendão longo do bíceps para o tratamento da instabilidade anterior do ombro. Nesta técnica, o tendão longo do bíceps braquial é desinserido do tubérculo supraglenoidal e transferido para a borda anterior da cavidade glenoidal, através da tenotomia do subescapular, reproduzindo o efeito tirante e aumentando o batente anterior. A técnica é de fácil execução, minimizando os riscos da transferência do processo coracoide e pode ser uma opção para o tratamento da instabilidade glenoumeral.

ABSTRACT Our objective is to describe the long biceps tendon transfer technique for the treatment of shoulder anterior instability. In this procedure, the long tendon of the biceps brachii is detached from the supraglenoid tubercle and transferred to the anterior edge of the glenoid cavity through a subscapularis tenotomy, reproducing the sling effect and increasing the anterior block. The technique is easy to perform and minimizes the risks of the coracoid process transfer. In conclusion, the transfer of the long tendon of the biceps brachii is an option for the treatment of glenohumeral instability.

Rotura espontánea del tendón extensor largo del pulgar ­ transferencia tendínea con técnica anestésica WALANT / Spontaneous rupture of thumb extensor pollicis longus ­ tendon transfer under the WALANT anesthetics technique

La rotura espontanea del tendón extensor largo del pulgar (ELP), es una patología infrecuente existiendo casos reportados en la literatura donde no se logra encontrar factores predisponentes. El manejo quirúrgico suele realizarse utilizando una técnica de transposición tendínea del tendón del extensor propio del índice. En la actualidad, la técnica anestésica de WALANT "Wide Awake Local Anesthesia with No-Torniquet" ha sido de amplio desarrollo en la cirugía de la mano, sobre todo para la resolución quirúrgica de patología de tendones, con buenos y excelentes resultados. Se presenta un caso de un paciente con rotura espontánea del tendón ELP, que fue manejado con una transferencia tendínea utilizando la técnica anestésica WALANT.

The spontaneous rupture of thumb extensor pollicis longus (EPL) is a rare disease with just a few case reports known where no trigger factor has been found. The surgical management is done by the proper index extensor tendon transposition. Nowadays, the WALANT anesthetic technique ("Wide Awake Local Anesthesia with No-Torniquet") has had a broad development in hand surgery, especially in surgery for tendon injuries, with good and excellent results. A clinical case is shown with a patient who had a spontaneous EPL rupture which was managed with a tendon transfer under the WALANT anesthetics technique.

Transferencia del deltoides posterior al tríceps braquial en pacientes con lesiones medulares cervicales / Transposition du deltoïde postérieur sur le triceps brachial chez un patient atteint des lésions médullaires au niveau cervical / Transfer of Posterior Deltoid to the Brachial Triceps in Patients with Cervical Spinal Cord Injuries

Introducción: durante mucho tiempo, casi 50 siglos, se pensó que la tetraplejía no tenía tratamiento. El mayor por ciento de lesiones medulares cervicales ocurre por accidentes de tránsito en pacientes jóvenes donde la pérdida de la extensión activa del codo limita sus habilidades de realizar actividades cotidianas tan sutiles como peinarse o cepillarse los dientes, por lo que se convierten en individuos totalmente dependientes. Objetivo: describir los resultados de la transferencia del deltoides posterior al tríceps braquial en pacientes tetrapléjicos. Mètodo: se realizó un estudio longitudinal prospectivo en el que fueron intervenidos 9 pacientes (14 transferencias) a los que se les aplicó la técnica de Castro Sierra (transferencia del deltoides posterior al tríceps braquial), para restablecer la extensión activa del codo. Resultados: el 100 por ciento de los pacientes intervenidos lograron la extensión activa del codo. El 57 por ciento (8 codos) con fuerza grado III y 43 por ciento (6 codos) con fuerza grado IV. Los 9 pacientes (100 por ciento) quedaron satisfechos con los resultados de su operación. No se reportaron complicaciones. Conclusiones: La transferencia del deltoides posterior al tríceps braquial permite realizar la extensión activa del codo en pacientes tetrapléjicos(AU)

Introduction: for a long, almost 50 centuries, tetraplegia was thought to be untreated. The highest percentage of cervical spinal cord injury occurs due to traffic accidents in young patients whose loss of active elbow extension limits their ability to perform daily activities as subtle as combing their hair or brushing their teeth, so that they become totally individuals dependent. Objective: describe the results of transferring the posterior deltoid to the triceps in quadriplegic patients. Method: a prospective longitudinal study was carried out in nine patients (14 transfers) who were operated on and Castro Sierra technique was applied (transfer of posterior deltoid to the triceps brachii) to restore active elbow extension. Results: 100 percent of the patients underwent active elbow extension. 57 pencert (8 elbows) with grade III strength and 43 percent (6 elbows) with grade IV strength. All the nine patients (100 percent) were satisfied with the results of their operation. No complications were reported. Conclusions: transfer of posterior deltoid to the brachial triceps allows the active extension of the elbow in quadriplegic patients(AU)

Introduction: pendant de nombreuses années, presque 50 siècles, on a pensé que la tétraplégie n'avait pas de traitement. La plupart des lésions médullaires d'atteinte cervicale sont produites à cause des accidents de la route chez de jeunes patients dont la perte de l'extension active du coude empêche leur capacité de réaliser quelques activités de la vie quotidienne, telles que se peigner ou se brosser les dents, devenant ainsi des handicapés. Objectif: l'objectif de cette étude est de décrire les résultats de la transposition du deltoïde postérieur sur le triceps chez des patients tétraplégiques. Méthodes: une étude longitudinale et prospective, suivant 9 patients traités chirurgicalement (14 transpositions) par la technique de Castro Sierra (transposition du deltoïde postérieur sur le triceps brachial) afin de rétablir l'extension active du coude, a été réalisée. Résultats: dans 100 pourcent des cas (dont 57 pourcent à force grade III (8 coudes), et 43 pourcent à force grade IV (6 coudes)), les patients opérés ont récupéré l'extension active du coude. Les 9 patients (100 pourcent) ont été satisfaits des résultats. Aucune complication n'a été trouvée. Conclusions: la transposition du deltoïde postérieur sur le triceps brachial permet de réaliser l'extension active du coude chez des patients tétraplégiques(AU)

Neurotization of free gracilis transfer with the brachialis branch of the musculocutaneous nerve to restore finger and thumb flexion in lower trunk brachial plexus injury: an anatomical study and case report

OBJECTIVE: To investigate the feasibility of using free gracilis muscle transfer along with the brachialis muscle branch of the musculocutaneous nerve to restore finger and thumb flexion in lower trunk brachial plexus injury according to an anatomical study and a case report. METHODS: Thirty formalin-fixed upper extremities from 15 adult cadavers were used in this study. The distance from the point at which the brachialis muscle branch of the musculocutaneous nerve originates to the midpoint of the humeral condylar was measured, as well as the length, diameter, course and branch type of the brachialis muscle branch of the musculocutaneous nerve. An 18-year-old male who sustained an injury to the left brachial plexus underwent free gracilis transfer using the brachialis muscle branch of the musculocutaneous nerve as the donor nerve to restore finger and thumb flexion. Elbow flexion power and hand grip strength were recorded according to British Medical Research Council standards. Postoperative measures of the total active motion of the fingers were obtained monthly. RESULTS: The mean length and diameter of the brachialis muscle branch of the musculocutaneous nerve were 52.66±6.45 and 1.39±0.09 mm, respectively, and three branching types were observed. For the patient, the first gracilis contraction occurred during the 4th month. A noticeable improvement was observed in digit flexion one year later; the muscle power was M4, and the total active motion of the fingers was 209°. CONCLUSIONS: Repairing injury to the lower trunk of the brachial plexus by transferring the brachialis muscle branch of the musculocutaneous nerve to the anterior branch of the obturator nerve using a tension-free direct suture is technically feasible, and the clinical outcome was satisfactory in a single surgical patient.

Wide-Awake Primary Flexor Tendon Repair, Tenolysis, and Tendon Transfer

Tendon surgery is unique because it should ensure tendon gliding after surgery. Tendon surgery now can be performed under local anesthesia without tourniquet, by injecting epinephrine mixed with lidocaine, to achieve vasoconstriction in the area of surgery. This method allows the tendon to move actively during surgery to test tendon function intraoperatively and to ensure the tendon is properly repaired before leaving the operating table. I applied this method to primary flexor tendon repair in zone 1 or 2, tenolysis, and tendon transfer, and found this approach makes tendon surgery easier and more reliable. This article describes the method that I have used for tendon surgery.

Recession-Resection Surgery Augmented with Botulinum Toxin A Chemodenervation for Paralytic Horizontal Strabismus

In this case series study, we assessed the effects of recession-resection surgery augmented with botulinum toxin A chemodenervation for patients with chronic paralytic horizontal strabismus. In addition, we compared these effects with those of full tendon transposition (FTT) augmented with posterior intermuscular suture (PIMS). Ten patients who underwent strabismus surgery due to paralytic horizontal strabismus were retrospectively reviewed. They received a recession-resection surgery augmented with botulinum toxin A chemodenervation (type I surgery) or a FTT augmented with PIMS (type II surgery). The preoperative angle of deviation (AOD) and postoperative improvement in AOD were compared according to the type of procedure. The preoperative AOD was 60.00 +/- 28.50 prism diopters (PD) for type I surgery and 68.00 +/- 27.06 PD for type II (p = 0.421). Improvement in AOD was 53.20 +/- 25.01 PD for type I surgery and 44.20 +/- 18.74 PD for type II (p = 0.548). Recession-resection surgery augmented with botulinum toxin A chemodenervation is a concise and effective procedure for treating paralytic horizontal strabismus.

Long-term effects of chronic achilles tendon rupture treatment, using reconstruction with peroneus brevis transfer, on sports activities / Efectos a largo plazo del tratamiento de la ruptura crónica del tendón de aquiles mediante reconstrucción con transferencia del peroneo corto en las actividades deportivas

OBJECTIVE: This study reports long-term effects of chronic Achilles tendon rupture treatment, using reconstruction with peroneus brevis transfer (PBT), on sports activities based on an approximate 10-year follow-up study. METHODS: Twenty patients (6 women and 14 men; mean age, 43 ± 12.85 years at the time of operation) underwent chronic Achilles tendon repair with an average follow-up of 164.05 ± 5.07 months. Seven were involved in competitive sports, 10 participated in recreational activities and three were not involved in any sporting activities. All patients were Asians. Results were assessed using Cybex strength testing and the American Othopaedic Foot and Ankle Society (AOFAS) Score, the muscle manual test (MMT), sports activities and comprehensive satisfaction assessment. RESULTS: Cybex strength testing resulted in an average gain of 87.05 ± 14.83% in dorsiflexion strength (range 65-110%) and 98.05 ± 9.02% in plantar flexion strength (range 85%-120%). The AOFAS score average was 86.9 ± 7.27. There were no postoperative re-ruptures, no recurrences and no wound complications. Plantar flexion strength and the AOFAS score were negatively correlated with the age at the time of operation (r = "0.566, r = -0.669, respectively). Seventeen patients (85%) were level five of MMT in eversion strength. Following treatment, six patients (30%) returned to competitive sports, while 10 (50%) who, prior to the injury and surgery, were involved in recreational activities, returned to similar activities. The relatively younger group tended to continue sport activities as competitive athletes (p < 0.05). Significant differences were observed in age at the operation between non-satisfaction group and excellent group (p < 0.05). The under 40-year age group tended to show a poor value. CONCLUSION: Recreational athletes and non-athletes could return to their sports activities satisfactorily, while young competitive athletes found difficulties in certain actions, especially related to eversion.

OBJETIVO: Este estudio reporta efectos a largo plazo del tratamiento de la ruptura crónica del tendón de Aquiles mediante reconstrucción con transferencia del peroneo corto (TPC) en actividades deportivas, sobre la base de un estudio de seguimiento de aproximadamente 10 años. MÉTODOS: Veinte pacientes (6 mujeres y 14 hombres; edad promedio, 43 ± 12.85 años en el momento de la operación) fueron sometidos a una reparación de ruptura crónica del tendón de Aquiles con un seguimiento promedio de 164.05 ± 5.07 meses. Siete estaban en medio de competencias deportivas, 10 participaban en actividades recreativas, y tres estaban fuera de toda actividad deportiva. Todos los pacientes eran los asiáticos. Los resultados se evaluaron usando la prueba de Cybex para medir la fuerza, la puntuación de la escala de la Sociedad Ortopédica Americana de Pie y Tobillo (AOFAS) para la valoración quirúrgica, la prueba muscular manual (PMM), y la evaluación integral de la satisfacción y las actividades deportivas. RESULTADOS: La prueba de Cybex indicó una ganancia promedio de 87.05 ± 14.83% en fuerza de dorsiflexión (rango 65-110%) y 98.05 ± 9.02% en fuerza de flexión plantar (rango 85%-120%). El promedio de la puntuación de la escala de AOFAS fue 86.9 ± 7.27. No se produjeron re-rupturas post-operatorias, ni recurrencias, ni complicaciones de heridas. La fuerza de flexión plantar y la puntuación de la escala AOFAS fueron puestas en correlación negativa con la edad al momento de la operación (r = "0.566, r = -0.669, respectivamente). Diecisiete pacientes (85%) alcanzaron el nivel cinco de la PMM en fuerza de eversión. Tras el tratamiento, seis pacientes (30%) se reintegraron a las competencias deportivas, mientras que 10 (50%) que antes de la lesión y la cirugía participaban en actividades recreativas, se reincorporaron a actividades similares. El grupo relativamente más joven tiende a continuar las actividades deportivas como atletas de competencia (p < 0.05). Se observaron diferencias significativas en edad en la operación entre el grupo sin satisfacción y el grupo excelente (p < 0.05). El grupo por debajo de los 40 años de edad mostró valores más pobres como tendencia. CONCLUSIÓN: Tanto los atletas de actividades recreativas como los no atletas, pudieron regresar a sus actividades deportivas satisfactoriamente, mientras que los competidores jóvenes encontraron dificultades en ciertas acciones, en particular las relacionadas con la eversión.

Transposición tendinosa con el palmar mayor para restablecer la extensión de los dedos en la parálisis del nervio radial / Tendinous transposition with palmaris major to restore the fingers extension in the radial nerve paralysis

INTRODUCCIÓN: Cuando se realizan transferencias tendinosas para restablecer la extensión de los dedos por parálisis del nervio radial ha sido motivo de controversia entre la decisión de que músculo a utilizar, el cubital anterior o palmar mayor. El objetivo de esta investigación es mostrar nuestra experiencia con el empleo del músculo palmar mayor. MÉTODOS: Se realizó un estudio longitudinal, en 39 pacientes con el diagnóstico de parálisis del nervio radial, donde se evaluó los resultados funcionales de las transposiciones tendinosas para restablecer la extensión de los dedos. El palmar mayor fue empleado en 27 pacientes, 15 por vía subcutánea y 12 a través de la membrana ánteríor ósea, y se utilizó cubital anterior en 12 pacientes como grupo control. RESULTADOS: La evaluación de la extensión de las articulaciones metacarpofalángicas de los dedos fue excelente y buena en 37 de los 39 pacientes sin que existiera asociación estadística en relación al músculo empleado. La fuerza muscular flexora de la muñeca después de la cirugía disminuyó a grado 3 en 11 de los 12 pacientes en que se utilizó el cubital anterior a diferencia de los que utilizaron el palmar mayor en los que la fuerza fue de grado 4 en 17 de los 27. La complicación más frecuente fue la desviación radial de la muñeca que se presentó en 4 pacientes, en todos se habÝa utilizado el cubital anterior. CONCLUSIONES: El músculo palmar mayor es la alternativa más recomendada para restablecer la extensión de los dedos en las parálisis del nervio radial

INTRODUCTION: When tendinous transfers are carried out to restore the finger extension due to radial nerve paralysis, there are controversies in the decision of which muscle be used, the anterior cubital one or the palmaris major. The objective of present research is to show our experience with the use of the palmaris major muscle. METHODS: A longitudinal study was conducted in 39 patients diagnosed with radial nerve paralysis, where we assessed the functional results of tendinous transpositions to restore the finger extension. The palmaris major was used in 27 patients, 15 by subcutaneous route and 12 through the interosseous membrane and the anterior cubital one was used in 12 patients as control group. RESULTS: The assessment of the extension of fingers metacarpophalangeal joints was excellent and good in 37 of the 39 patients without statistic association in relation to the muscle used. The flexor muscular strength of wrist after surgery decreased at grade 3 in 11 of the 12 patients in which we used the anterior cubital one unlike those used the palmaris major where the strength was of grade 4 in 17 of the 27 patients. The more frequent complication was the wrist radial deviation present in 4 patients in which we used the anterior cubital one. CONCLUSIONS: The palmaris major muscle is the more recommended alternative to restore the fingers extension in radial nerve paralyses

ECRL--a wrist extensor with multiple uses in deformity correction.

Extensor carpi radialis longus muscle has been used in various types of procedures for corrective hand surgery and is a favored muscle for correction of finger clawing due to ulnar nerve palsy in leprosy because its removal leaves an insignificant motor deficit and gives a linear scar at the donor site. It is usually not paralyzed in leprosy. The muscle, being phasic, is easy to re-educate. The excursion of the muscle is similar to lumbrical muscles which it substitutes. Since the muscle is dorsally located, the transfer does not lose tension due to adaptive wrist flexing habit. Its tendon is usually thick enough, can be split into two and used as graft to elongate the muscle-tendon unit or for ligament reconstruction in cases of trapezio-metacarpal joint arthritis.

Extensor indicis proprius transfer for the abducted small finger

PURPOSE: Persistent abduction of the small finger has usually been treated by transfer of the extensor digiti minimi muscle. However, anatomic variations of the extensor system may limit the potential for a successful extensor digiti minimi transfer. Therefore, we evaluated the outcomes of an alternative reconstruction method for the abducted small finger using an extensor indicis proprius (EIP) transfer. METHODS: We performed 8 EIP transfers in 8 patients with persistent, flexible abduction posturing of the small finger. The primary etiology of the deformity was incomplete motor reinnervation after surgeries for ulnar neuropathy in 6 patients, rupture of the third palmar interosseous musculotendinous unit in 1 patient, and intrinsic muscle fibrosis in 1 patient. The EIP was elongated by splitting the tendinous portion and was transferred to the distal and radial part of the extensor hood. Surgical outcomes were assessed by comparing preoperative and postoperative active adduction and abduction motion of the 2 ulnar digits. RESULTS: At the mean follow-up of 23 months, the average adduction angle improved from 19 degrees to 1 degrees postoperatively. In terms of active finger motion, 6 patients showed excellent results, 1 good, and 1 fair, without loss of flexion and extension. No patient had an extension lag or complained of functional deficits of the donor index finger. There was not adverse change to digital function or range of motion for the middle and ring fingers that are crossed by the EIP. CONCLUSIONS: Extensor indicis proprius transfer can be a reliable option for correction of abduction deformity of the small finger, maintaining active abduction and full flexion and extension. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Vertical Rectus Muscles Transposition in Large Exotropia with Medial Rectus Muscle Transection Following Endoscopic Sinus Surgery

PURPOSE: To evaluate the effect of transposition procedures on the vertical rectus muscle (VRM) in the patients who underwent a medial rectus muscle (MR) transection after endoscopic sinus surgery (ESS). METHODS: In 4 patients with exotropia (XT) and a lack of adduction after ESS, orbital CT or MRI revealed a complete transection of the midportion of the MR. Full-tendon VRM transposition was performed within 3 months after injury (early surgery) in 2 patients with 40delta XT. Two patients with 70delta and 85delta XT underwent an X-type augmented Hummelsheim procedure, which involved pulling each half-tendon and crossing it through the undersurface of the severed MR to the other end of the MR insertion, concurrently with an ipsilateral lateral rectus (LR) recession 11 months and 36 months after ESS, respectively. The adduction deficits were divided into -1 through to -8. The patients were followed up for more than than 1.5 years. RESULTS: Postoperatively, 3 patients showed orthophoria and no diplopia in the primary position. The adduction deficits improved to -3.5 or -4. One patient who underwent an X-type augmented Hummelsheim procedure showed a residual XT of 25delta. CONCLUSIONS: VRM transposition is effective in correcting a large XT secondary to a MR transection after ESS. When a longstanding large-angle XT with severe contracture of the ipsilateral LR and massive scarring of the adjacent tissues is present, the X-type augmented Hummelsheim procedure coupled with an ipsilateral LR recession had an augmenting effect.

Plastia de Lapidus en el tratamiento quirúrgico del quinto ortejo supra aducto / Lapidus procedure for treatment of overlapped fifth toe

The varus fifth toe pathology, in spite of its relative frequency and clinical relevance, has been barely studied in relation to the treatment results. 28 overlapped fifth toes operated according to the Lapidus Technique were evaluated retrospectively, corresponding to 17 patients, age average 28 years, opered since year2003. The minimum follow up time was 6 months. The surgical technique consisted on a dorsal approach in "italic s" on the 5° metatarsophalangic joint, capsulotomy and transference of the EDL to the digiti quinti abductor. Preoperative Hallux Metatarsophalangeal-lnterphalangeal AOFAS Scale average was 88,1 and varied to 99,4 points to the six months of pursuit. 100% of the patients showed complete satisfaction with the result.
