Skeletal muscle wasting, associated with aging, may be regulated by the inflammatory cytokines as well as by insulin-like growth factor 1 (IGF-1). l-carnitine possesses anti-inflammatory properties and increases plasma IGF-1 concentration, leading to the regulation of the genes responsible for protein catabolism and anabolism. The purpose of the present study was to evaluate the effect of a 24-week l-carnitine supplementation on serum inflammatory markers, IGF-1, body composition and skeletal muscle strength in healthy human subjects over 65 years of age...

Despite the fact that there are numerous reports on muscular variations in the sole of the foot, routine dissection in a formaldehyde-fixed cadaver revealed an accessory flexor digiti quinti muscle, which to the best of our knowledge is a very unusual variant. This was in the form of a slender, 38 mm long muscular slip, with a proximal and distal tendon extending from the common flexor digitorum longus tendinous plate out to the distal phalanx of the fifth toe. An associated finding was the absence of the musculotendinous portion of the flexor digitorum brevis to the same toe...

INTRODUCTION: Neck pain is the leading cause of years lived with disability worldwide and it accounts for high economic and societal burden. Altered activation of the neck muscles is a common musculoskeletal impairment presented by patients with neck pain. The craniocervical flexion test with pressure biofeedback unit has been widely used in clinical practice to assess function of deep neck flexor muscles. This systematic review will assess the measurement properties of the craniocervical flexion test for assessing deep cervical flexor muscles...

The aim of this study was to evaluate the relationship between muscle activity and inter-muscle contributions patterns and postural control during a handstand. Additionally, outcomes were compared between young and adult gymnasts (mean ± SD: 13.9 ± 0.7 and 23 ± 3 years respectively). Participants performed three trials of a 10 s handstand on a force platform with simultaneous EMG signal recording at the upper and lower limbs. Adult gymnasts demonstrated significantly better postural control in each studied variable...

Florian Monjo, Nicolas Forestier
This study was designed to explore the effects of intrafusal thixotropy, a property affecting muscle spindle sensitivity, on the sense of force. For this purpose, psychophysical measurements of force perception were performed using an isometric force matching paradigm of elbow flexors consisting of matching different force magnitudes (5, 10 and 20% of subjects' maximal voluntary force). We investigated participants' capacity to match these forces after their indicator arm had undergone voluntary isometric conditioning contractions known to alter spindle thixotropy, i...

Background: Diabetic foot ulcers are frequently related to elevated pressure under a bony prominence. Conservative treatment includes offloading with orthopaedic shoes and custom made orthotics or plaster casts. While casting in plaster is usually effective in achieving primary closure of foot ulcers, recurrence rates are high. Minimally invasive surgical offloading that includes correction of foot deformities has good short and long term results. The surgery alleviates the pressure under the bony prominence, thus enabling prompt ulcer healing, negating the patient's dependence on expensive shoes and orthotics, with a lower chance of recurrence...

In order to characterize the physiological adjustments within the neuromuscular system that contribute to task failure, this study examined the surface mechanomyographic (MMG) response during maximal and submaximal isometric force tasks of the elbow flexors sustained to failure. The time and frequency components of the MMG signal have shown to be influenced by motor unit activation patterns as well as tetanus. Therefore, it was hypothesized that the rate of change for the MMG response would associate with failure times and would be reduced to a similar degree between the two tasks...

Eosinophilic fasciitis (EF), a rare rheumatic disease, usually affects the limbs symmetrically and generally spares the hands and feet. Cases of unilateral hand involvement are rarely reported. Here, we report such a rare case. Ultrasonography demonstrated thickening of the overlying skin and subcutaneous tissue, peripheral deep fascia, myositis of lumbrical muscles and adductor pollicis muscle, and edema surrounding flexor digitorum tendons. It reminds us that EF should be considered in the differential diagnosis of unilateral painful hand swelling despite being uncommon...

The purpose of the present study was to determine whether overlap (redundancy) exists between individual tests in a comprehensive strength testing protocol used after anterior cruciate ligament (ACL) reconstruction surgery. If overlap is present, one or more components of the protocol could potentially be omitted to make the testing protocol more efficient, but without compromising the usefulness of the testing.Sixty-nine patients (46M, 23F; mean age 28Y) were strength tested at 6 and 12 months after ACL reconstruction as part of a prospective cohort study...

The structure of the limbs of elephants is unusual among mammals. In African elephants (Loxodonta africana, Blumenbach 1797), the front limbs serve to support the greatest part of the body mass of the largest land animal. In this study, we present new and detailed anatomical data regarding muscular and specific fascial structures of the lower front limb which were examined by means of standard anatomical and histological techniques. The muscles and tendons of the forearm (antebrachium) and hand (manus) are tightly surrounded by thick, highly elastic fascial layers which fuse with the lacertus (lac...

BACKGROUND: Trigger finger is a common clinical disorder, characterised by pain and catching as the patient flexes and extends digits because of disproportion between the diameter of flexor tendons and the A1 pulley. The treatment approach may include non-surgical or surgical treatments. Currently there is no consensus about the best surgical treatment approach (open, percutaneous or endoscopic approaches). OBJECTIVES: To evaluate the effectiveness and safety of different methods of surgical treatment for trigger finger (open, percutaneous or endoscopic approaches) in adults at any stage of the disease...

Cervical spondylotic amyotrophy is characterized by severe, proximal upper extremity weakness including an inability to abduct the shoulder and flex the elbow. Treatment using both medical and surgical decompression approaches has produced variable results. This paper reports the use of nerve transfers (spinal accessory to suprascapular, flexor carpi ulnaris fascicle of ulnar to biceps motor branch, radial nerve branch to triceps to axillary) to restore shoulder and elbow function in a case of unilateral cervical spondylotic amyotrophy involving C5 and C6 myotomes...

We report outcomes in 29 patients with flexor tendon repairs in 32 digits (five thumbs and 27 fingers) with our modified protocols. We repaired the lacerated flexor digitorum profundus tendons with core suture repairs using the 6-strand M-Tang method and without circumferential sutures. We divided the pulleys as much as needed to allow excursion of the repaired tendons, including complete division of the A4 or A2 pulleys when necessary. In nine fingers, we repaired one slip of the flexor digitorum superficialis tendon and resected the other half...

This study compared the biomechanical performance of a novel 6-strand asymmetric flexor tendon repair with the modified Lim-Tsai technique using cyclic testing. Two groups of ten porcine tendons each were repaired and tested. Gap formation at every 100 cycles was measured. Survival was defined as maximum gap formation below 2 mm. All the repairs survived Stage I. With increased cyclic load in Stage II, the mean gap formation of modified Lim-Tsai repairs exceeded 2 mm at the 600th cycle and reached 4.2 mm (SD 1...

Guillaume Christe, Toby Hall
Background: Thoracic disc herniations are rare and difficult to diagnose. Myelopathy is a potential consequence that can lead to irreversible neurological impairment if not treated appropriately. It is incumbent on all clinicians who see patients with low back pain (LBP) to be aware of such pathologies. This case describes a screening process in the detection of a rare serious spinal pathology and discusses the use of red flags and central nervous system signs and symptoms in the decision leading to immediate referral...

#18
Jin Park, Jin Ho Che
Talus fracture of the medial tubercle of the posterior process is rare. This type of fracture can be easily missed, because it is difficult to identify on plain radiographs of the ankle. Oblique radiographs with external rotation, computed tomography, and magnetic resonance imaging (MRI) of the ankle are useful for making an accurate diagnosis. However, even with an early diagnosis, the treatment guidelines for talus fractures of the posterior medial tubercle have not yet been established. The flexor hallucis longus (FHL) tendon, which passes through the groove between the medial and lateral tubercles of the posterior process of the talus, can interpose between the fracture sites and interrupt fracture reduction...

PURPOSE: Trigger finger, also referred to as stenotic flexor tenosynovitis, is a common condition affecting the digits, with a lifetime incidence of 2.6% among the healthy population and up to 16.5% in diabetic patients. Diabetes mellitus is associated with multiple musculoskeletal conditions including trigger finger. In this study, we aimed to compare the functional outcome of trigger finger release in diabetic and nondiabetic patients to evaluate whether the management of trigger finger in diabetic patients should be the same as that in nondiabetic patients, or whether diabetic patients would benefit from a more tailored management plan to optimize results...

"Defense" type wounds are sustained when a victim is attempting to ward off an attacker, or a weapon. A 39-year-old woman is reported who was found deceased with incised wounds to the dorsa of both hands that resembled defense wounds. Examination of the flexor surfaces of both wrists, however, revealed horizontal incised wounds typical of self-infliction. Perfusion of the subclavian arteries produced leakage of water from peripheral veins within wounds on both hands and the right wrist. Death was due to exsanguination from incised wounds of the hands and right wrist; manner suicide...
