Palmaris Longus Tendon

Spontaneous ruptures of the flexor carpi radialis tendon (FCR) are rare and associated with systemic inflammatory diseases, localized tendinopathy related to scaphotrapezial-trapezoidal arthritis, or chronic immunosuppression from corticosteroids. While most cases do not require operative intervention, some patients develop weakness, impaired range of motion, and persistent pain. Previously reported surgical options include synovectomy, tendon stump resection, and osteophyte removal. We describe a surgical technique for patients with persistent symptomatology following FCR rupture in which the FCR is transposed end-to-side to the palmaris longus tendon. Three cases using this technique are presented with follow-up of 4–9 months that were collected at Lenox Hill Hospital. All three patients did well regarding specific outcome measures: grip strength, range of motion, and functional activity. FCR transfer to palmaris is an alternative to other surgical options for the spontaneous rupture of the FCR tendon in patients who remain symptomatic despite a course of non-operative therapy.

Background Current surgical treatments for acromioclavicular separations do not re-create the anatomy of the acromioclavicular joint. Hypothesis Anatomical acromioclavicular reconstruction re-creates the strength of the native acromioclavicular joint and is stronger than a modified Weaver-Dunn repair. Study Design Controlled laboratory study. Methods The native acromioclavicular joint in 6 fresh-frozen cadaveric upper extremities was stressed to failure under uniaxial tension in the coronal plane. A modified Weaver-Dunn procedure, anatomical acromioclavicular reconstruction using a palmaris longus graft, and anatomical acromioclavicular reconstruction using a flexor carpi radialis graft were then performed sequentially. Each repair was stressed to failure. Load-displacement curves and mechanism of failure were recorded for each. Results Loads at failure for the native acromioclavicular joint complex, modified Weaver-Dunn procedure, anatomical acromioclavicular reconstruction using a palmaris longus tendon graft, and anatomical acromioclavicular reconstruction using a flexor carpi radialis tendon graft were 815 N, 483 N, 326 N, and 774 N, respectively. The strength of the native acromioclavicular joint complex was significantly different from the modified Weaver-Dunn repair (P <. 001) and the anatomical acromioclavicular reconstruction using a palmaris longus tendon graft (P <. 001) but not from the anatomical acromioclavicular reconstruction using a flexor carpi radialis tendon graft (P =. 607). Conclusion The strength of the described anatomical acromioclavicular reconstruction is limited by the tendon graft used. Anatomical acromioclavicular reconstruction with a flexor carpi radialis tendon graft re-creates the tensile strength of the native acromioclavicular joint complex and is superior to a modified Weaver-Dunn repair.

Various aberrant muscles and fibro-tendinous structures have been identified in the anterior wrist, some of them blamed to be possible causes for neurovascular compression syndromes. Herewith, we describe such an intriguing structure related to the flexor carpi ulnaris muscle. During routine dissection of both upper limbs of an adult cadaver, an interesting crescent-shaped fibro-tendinous structure was identified bilaterally, arising broadly from the lateral side of the distal tendon of the flexor carpi ulnaris. This aberrant structure arched over the ulnar artery and nerve before they enter the canal of Guyon and the median nerve just before the carpal tunnel. Further distally, the fibro-tendinous arch narrowed and interlaced with the flexor retinaculum and palmar aponeurosis longitudinal fibres. In this case there was also concomitant bilateral absence of the palmaris longus muscle. Because this aberrant fibro-tendinous arch has very close relations to the median nerve and ulnar nerve and artery in the wrist, it may possibly cause neurovascular compression during some muscle activity.Varios músculos y estructuras fibro-tendinosas aberrantes se han identificado en la parte anterior de la muñeca, muchas de las cuales se considera que pueden causar síndromes de compresión neurovascular. A continuación describimos una tal estructura relacionada con el músculo flexor carpi ulnaris. Durante disecciones de rutina de ambos miembros superiores de cadáveres de adultos fue descubierta una estructura fibro-tendinosa con forma de medialuna en ambos miembros originando de la parte lateral del tendón distal del flexor carpi ulnaris. Esta estructura formaba un arco pasando sobre y cubriendo la arteria y el nervio ulnar antes de que entren en el canal de Guyon, y sobre el nervio mediano justo antes de que entre en el canal carpal. Este arco fibro-tendinoso seguía estrechándose hasta entrelazarse con el ligamento transverso del carpo y las fibras longitudinales de la aponeuorisis palmar .En este mismo caso el músculo palmaris longus estaba ausente en ambas manos. Esta conexión entre el arco fibro-tendinoso y el nervio mediano, la arteria y el nervio ulnar en la muñeca posiblemente puede causar compresión neurovascular durante cierta actividad muscular.

Flexor Carpi Ulnaris

The flexor-pronator mass is thought to be the primary dynamic valgus stabilizer of the elbow and protects the ulnar collateral ligament. However, in vivo multiaxis actions of individual muscles of the flexor-pronator group and their roles in valgus stability have not been investigated quantitatively. This study tested the hypothesis that individual muscles of the flexor-pronator muscle group produce a significant varus moment that provides elbow valgus stability. The flexor carpi ulnaris, flexor carpi radialis, and pronator teres were selectively activated, and the resulting multiaxis moments at the elbow measured at 0°, 30°, 60°, and 90° of elbow flexion using a six-axis force sensor were analyzed for their role in generating varus moment and protecting the ulnar collateral ligament. Considerable off-axis moments were generated by each muscle tested. Through the range of elbow flexion, the varus moment was the major component of the multiaxis action of the flexor carpi ulnaris (p< .001). The flexor carpi radialis and pronator teres had significant actions as elbow flexors and pronators (p≤ .032); these muscles also had a significant varus contribution at 90° elbow flexion (p≤.019). The results suggest that the flexor-pronator muscle group plays an important role in valgus stability of the elbow. In particular, the flexor carpi ulnaris creates a significant varus moment, which is important in unloading and protecting the ulnar collateral ligament. Rehabilitation and strengthening of the flexor-pronator muscle group may help prevent failure of the ulnar collateral ligament and may also help compensate for a medially insufficient elbow.
