BACKGROUND: Closed avulsion injury of the flexor digitorum profundus (FDP) tendon is a relatively common condition of the hand. Its present classification system seems to be deficient in including all possible patterns of injury, leading to improper selection of the best treatment method for the injury. We aim to provide a new classification scheme for this injury. METHODS: We developed a new classification scheme based on the possible pattern of FDP tendon injury...

Neil D Reeves, Glen Cooper
The Achilles is a long tendon varying in cross-sectional area (CSA) considerably along its length. For the same force, a smaller CSA would experience higher tendon stress and we hypothesised that these areas would therefore undergo larger transverse deformations. A novel magnetic resonance imaging-based approach was implemented to quantify changes in tendon CSA from rest along the length of the Achilles tendon under load conditions corresponding to 10, 20 and 30% of isometric plantar flexor maximum voluntary contraction (MVC)...

Nerve entrapment syndromes occur because of anatomic constraints at specific locations in both upper and lower limbs. Anatomical locations prone to nerve entrapment syndromes include sites where a nerve courses through fibro-osseous or fibromuscular tunnels or penetrates a muscle. The median nerve (MN) can be entrapped by the ligament of Struthers; thickened biceps aponeurosis; between the superficial and deep heads of the pronator teres muscle and by a thickened proximal edge of flexor digitorum superficialis muscle...

: We repaired complete divisions of flexor tendons in zone 2 in 54 fingers using a six-strand core M-Tang repair method. Partial active digital motion started with early passive digital motion carried out first in the first 3-4 weeks after surgery and full range of active motion in later weeks. The patients were followed for 4-27 months. According to Strickland criteria or Tang criteria, 24 (83%) had excellent or good, four fair and one poor results in 28 fingers with follow-up of more than one year...

Enabling motor control by epidural electrical stimulation of the spinal cord is a promising therapeutic technique for the recovery of motor function after a spinal cord injury (SCI). Although epidural electrical stimulation has resulted in improvement in hindlimb motor function, it is unknown whether it has any therapeutic benefit for improving forelimb fine motor function after a cervical SCI. We tested whether trains of pulses delivered at spinal cord segments C6 and C8 would facilitate the recovery of forelimb fine motor control after a cervical SCI in rats...

Tendon is a connective tissue mainly composed of collagen fibers with peculiar mechanical properties essential to functional movements. The increasing incidence of tendon traumatic injuries and ruptures-associated or not with the loss of tissue-falls on the growing interest in the field of tissue engineering and regenerative medicine. The use of animal models is mandatory to deepen the knowledge of the tendon healing response to severe damages or acute transections. Thus, the selection of preclinical models is crucial to ensure a successful translation of effective and safe innovative treatments to the clinical practice...

The ulnar collateral ligament (UCL) of the elbow acts as the primary restraint to valgus force experienced in the late cocking and early acceleration phases of overhead throwing. If the UCL or dynamic flexor-pronator musculature is incompetent, elbow extension and valgus torque, as seen in throwing, can result in posteromedial impingement with subsequent chondromalacia and osteophyte formation. Before the first UCL reconstruction, performed by Frank Jobe in 1974, this injury was considered career ending in overhead athletes...

Over the past few years, a number of cases of tendon injuries associated with statin therapy have been reported. In this study, we assessed whether statins can affect the extracellular matrix (ECM) of the deep digital flexor tendon (DDFT) and patellar tendon (PT). Wistar rats were assigned to groups treated with atorvastatin (A20, A80), treated with simvastatin (S20, S80), and control. Zymography, Western blotting for collagen I, non-collagenous proteins (NCP), glycosaminoglycans (GAGs), and hydroxyproline quantifications were performed...

Severe burn injuries are associated with hypermetabolic response and increased catabolism. These lead to a vast loss of muscle mass and reduced muscle strength and function. Therefore, the aim of this study is to determine the impact of severe burn injuries on lower-limb muscular strength, balance, and mobility level in adults. Forty burned adults with burned TBSA (burned TBSA) ≥40% participated in this study. The peak torque and total work of quadriceps and knee flexors were calculated at 150°/sec using Biodex isokinetic dynamometer...

Degenerative and traumatic ligament lesions of the carpometacarpal joints frequently occur at the thumb ray, whereas the carpometacarpal amphiarthrosis of other finger rays are rarely affected. The metacarpophalangeal and interphalangeal joints of the thumb and fingers are stabilized by bilaterally running collateral ligaments and palmar plates. At the base of the metacarpophalangeal joints, several ligaments of the extensor hoods guide the extensor tendons and coordinate the fine motoric skills of phalangeal flexing and extending...

A 43-year-old man presented with weakness of the interphalageal joint of his right thumb following the use of forearm crutches. On examination he was unable to oppose his thumb and index finger to form the 'ok' sign. Nerve conduction showed anterior interosseous nerve (AIN) damage along its path to the flexor pollicis longus. The patient was managed conservatively with little clinical improvement seen at 4 months. AIN palsies are very rare and account for <1% of all upper limb lesions. Although AIN palsies resulting from other causes such as surgery and blunt trauma are more common, we report the second case of AIN palsy following crutch use, and the first case in which clinical identification was confirmed using electrodiagnosis...

A 52-year-old male complained of numbness and radiating pain affecting the plantar region of his left foot. He was found to have recurrent tarsal tunnel syndrome due to posterior tibial nerve compression by 3 different types of ganglion during a 12-year period. To the best of our knowledge, a similar case has not been documented. At the first operation, flexor retinaculum release and simple excision of an epineural ganglion were performed without injuring the nerve fascicles; however, an intrafascicular ganglion developed approximately 2 years later...
