flexor digitorum longus

F G Usuelli, C A Di Silvestri, R D'Ambrosi, C Maccario, E W Tan
PURPOSE: Medial displacement calcaneal osteotomy with flexor digitorum longus transfer is a common treatment for the management of the adult flatfoot associated with posterior tibial tendon dysfunction. In the literature, there is a paucity of information regarding the ability of patients to return to sport and recreational activities after this surgical procedure. The purpose of this retrospective clinical study was to assess the rate and type of athletic activities that patients participated in before and after medial displacement calcaneal osteotomy with flexor digitorum longus transfer...

Tendon connects skeletal muscle and bone, facilitating movement of nearly the entire body. In the hand, flexor tendons (FTs) enable flexion of the fingers and general hand function. Injuries to the FTs are common, and satisfactory healing is often impaired due to excess scar tissue and adhesions between the tendon and surrounding tissue. However, little is known about the molecular and cellular components of FT repair. To that end, a murine model of FT repair that recapitulates many aspects of healing in humans, including impaired range of motion and decreased mechanical properties, has been developed and previously described...

This study was designed to find a possible correlation between the presence of the palmaris longus and function of the fifth flexor digitorum superficialis. We examined 300 participants to assess the absence of palmaris longus and flexor digitorum superficialis function by several clinical tests. Overall absence of palmaris longus, was seen in 157 participants (52.3%). Overall deficiency of flexor digitorum superficialis was noted in 100 participants (33.3%). In 15 participants (5%) we noted bilateral absence of palmaris longus and flexor digitorum superficialis deficiency...

OBJECTIVE: To assess, utilizing MRI, tarsal tunnel disease in patients with talocalcaneal coalitions. To the best of our knowledge, this has only anecdotally been described before. MATERIALS AND METHODS: Sixty-seven ankle MRIs with talocalcaneal coalition were retrospectively reviewed for disease of tendons and nerves of the tarsal tunnel. Interobserver variability in diagnosing tendon disease was performed in 30 of the 67 cases. Tarsal tunnel nerves were also evaluated in a control group of 20 consecutive ankle MRIs...

BACKGROUND: The purpose of this study was to explore the relation between muscle MRI findings and weakness of the upper extremity muscles in patients with myotonic dystrophy type 1 (DM1). METHODS: Nineteen DM1 patients from 15 families were enrolled in this study. Muscle weakness was evaluated using the modified Medical Research Council scale. Subjects also underwent a genetic study and muscle MRI of the upper extremities. RESULTS: In patients with DM1, the flexor digitorum profundus (FDP), flexor pollicis longus, flexor digitorum superficialis (FDS), extensor pollicis, abductor pollicis longus (APL), lateral head of triceps brachii and infraspinatus (INF) muscles were frequently and severely affected...

Long-standing rheumatoid arthritis can result in spontaneous tendon rupture caused by attrition of the tendons. Ruptures of the ulnar-sided extensor tendons, flexor pollicis longus, and the flexor digitorum profundus can be seen. Primary repair of these tendon ruptures is frequently not possible because of delayed presentation and tendon damage by the disease process. Tendon transfers are the preferred method of treatment in patients with rheumatoid arthritis. At surgery, it is critical to address the underlying cause of rupture to prevent future tendon ruptures...

UNLABELLED: Coxa pedis is the talocalcaneonavicular joint and is the distal enarthrosis of the lower limb. It is defined coxa because of: (1) the enarthrosic meaning from an anatomical point of view, (2) the analogy to the hip. The stabilising devices are structural, passive and active; the corresponding pathology is the "Coxa pedis destabilising syndrome". During walking, release and stiffening of the foot are related to the opening and closure of the kinetic chain of the coxa pedis: it is mutually reversible, while opening is a passive event, closure is an active one...

Total ankle replacement studies have focused on reporting complications that are directly observed clinically or radiographically, including wound problems, technical errors, implant loosening, subsidence, infection, bone fractures, and heterotopic ossification. However, patients can still experience unresolved pain even when these problems have been ruled out. We initiated a study to more clearly define the relative risk of injury to the anatomic structures in the posterior ankle during total ankle replacement using a third-generation implant system...

OBJECTIVE A thorough understanding of anatomy is critical for successful carpal tunnel release. Several texts depict the median nerve (MN) as taking a course parallel to the long axis of the forearm (LAF). The authors report on their attempt to formally assess the course of the MN as it travels to the carpal tunnel in the distal wrist and discuss its potential clinical significance. METHODS The width of the wrist, the distance from the radial wrist to the MN, and the distance from the distal volar wrist crease to the point where the MN emerges between the flexor carpi radialis (FCR) tendon and the flexor digitorum superficialis (FDS) tendons were recorded during cadaveric dissection of 76 wrist specimens...

Flexor hallucis longus (FHL) tendon transfer is indicated for reconstruction of the Achilles tendon with a gap larger than 5 cm. The tendon can be harvested at zone 2 or zone 3 by minimally invasive techniques with the advantage of minimal soft-tissue dissection. The tendon can be harvested under the sustentaculum tali by zone 2 FHL tendoscopy. It is adequate for FHL transfer to the posterior calcaneal tubercle. If a double-thickness reconstruction of a huge gap of the Achilles tendon is indicated, the tendon can be harvested at the level of the hallux by means of a tendon stripper...

The muscles of the anterior compartment of the forearm often exhibit anatomic variations. During dissection of the upper right limb of a preserved cadaver, morphological variations in the Palmaris longus and Flexor digitorum superficialis muscles were found. The Palmaris longus muscular fibers converged to a tendon that passed beneath the Flexor retinaculum, and inserted at the base of the middle phalanx of the fourth digit, replacing the tendon of Flexor digitorum superficialis. The Flexor digitorum superficialis was divided into two muscular heads: a digastric medial head giving tendons to the second and fifth digits, and a lateral head giving one tendon to the third digit...

BACKGROUND: Lateral epicondylalgia is a common musculoskeletal disorder and is associated with deficits in the motor system including painful grip. This study compared coordination of forearm muscles (muscle synergies) during repeated gripping between individuals with and without lateral epicondylalgia. METHODS: Twelve participants with lateral epicondylalgia and 14 controls performed 15 cyclical repetitions of sub-maximal (20% maximum grip force of asymptomatic arm), pain free dynamic gripping in four arm positions: shoulder neutral with elbow flexed to 90° and shoulder flexed to 90° with elbow extended both with forearm pronated and neutral...

It is uncommon to have additional muscles in the upper limb. Some of them may restrict the movements or compress the nerves and vessels, while others may go unnoticed. During the routine dissection for undergraduate medical students, we observed an additional muscle in the anterior compartment of the forearm in about 60-year-old male cadaver. The muscle had a prominent belly and a long tendon. Distally, it was attached to the flexor retinaculum by a short and thick tendon. Proximally, long tendon of the muscle passed between the flexor carpi ulnaris and palmaris longus and was attached to the common aponeurosis shared by the extensor carpi ulnaris and flexor digitorum profundus muscles...

This case report describes a patient who presented with a complete rupture of the flexor pollicis longus (FPL) tendon and partial rupture of the flexor digitorum profundus of the index finger, secondary to scaphoid nonunion. This is a rare, late complication that deserves to be described because of the potential diagnostic confusion with anterior interosseous nerve palsy. No case has been reported since 1999 in the literature. The mechanism was an attrition rupture due to sharp osteophytes. The scaphoid osteophytes were removed and the FPL was repaired by tendon transfer...

Traumatic musculotendinous junction avulsions are rare injuries except in avulsion amputations. They pose a significant challenge to the treating surgeon. We present a 24-year-old male who sustained an open musculotendinous avulsion of the flexor pollicis longus tendon. He was treated with primary tendon transfer using the flexor digitorum superficialis of ring finger, in flexor zone 3. The functional result at 10 months following surgery was excellent.
