Eccentric training is an established training method in competitive sports. It has been used effectively to improve muscle strength during rehabilitation after cruciate ligament reconstruction. However, it is still uncertain whether or not eccentric training contributes to successful rehabilitation after apophysis fractures. A fourteen-year-old soccer player, forward position, presents with an apophysis avulsion located at the right spina iliaca anterior inferior. After completing an early rehabilitation phase and isokinetic concentric strength development, the patient starts an eccentric training programme eight weeks after the injury, including training on an isokinetic dynamometer (Biodex) for four weeks, followed by a four-week eccentric ergometer training (Eccentron)...

BACKGROUND: In adults with lower trunk brachial plexus injury, proximal nerve surgery for restoration of prehension demonstrates poor outcomes secondary to long distances required for nerve regeneration and time-dependent degradation of motor endplates. Options for reconstruction are limited to distal tendon or nerve transfers and free-functioning muscle transfers. In this article, the authors describe the long-term outcomes of brachialis muscle-to-flexor digitorum profundus transfer to restore prehension in patients with traumatic lower trunk brachial plexus injuries...

BACKGROUND: The integrity of the flexor tendon pulley apparatus is crucial for unimpaired function of the digits. Although secondary reconstruction is an established procedure in multi-pulley injuries, acute reconstruction of isolated, closed pulley ruptures is a rare occurrence. There are 3 factors influencing the functional outcome of a reconstruction: gapping distance between tendon and bone (E-space), bulkiness of the reconstruction, and stability. As direct repair is rarely done, grafts are used to reinforce the pulley...

Wen-Tzu Tang, Wei-Chih Liao, Hsin-Min Lee
To investigate characteristic upper limb muscle use between two common tug of war (TOW) gripping styles, 20 elite athletes from two high school TOW teams were recruited. Under conditioned attack pulling (with 90% maximal force) on a tug machine, participants used their own habitual gripping style to pull for five 15-s trials. Force and kinematic measurements showed a significantly better force performance and higher centre-of-gravity tilting angle with the gripping style one than with the gripping style two (GS2) (both p < 0...

Injury to the flexor pollicis longus (FPL) tendon is one of the most frequent complications when fixing distal radius fractures with the volar locking plates. The author proposed a simple surgical technique providing a reliable soft tissue protection to prevent friction on the FPL with the volar locking plate, using a flap of the FCR sheath sutured to attachments of the volar capsule on the lunate buttress facet of the distal radius.

Core muscle imbalances and weak trunk strength are relevant for injury prevention and performance. Information regarding core strength requirements and ideal flexion/extension ratios in alpine skiing is limited. We aimed to compare trunk strength capacities in elite alpine skiers with those of a matched control group. The concentric maximal trunk flexion and extension of 109 elite skiers and 47 active controls were measured at 150°/s in a ballistic mode using the CON-TREX® TP 1000 test system. The relative flexion peak torque was higher in male ski racers (p = 0...

Tendon injuries are encountered after major and minor hand trauma. Despite meticulous repair technique, adhesion formation can occur, limiting recovery. Although a great deal of progress has been made toward understanding the mechanism of tendon healing and adhesions, clinically applicable solutions to prevent adhesions remain elusive. The goal of this paper is to review the most recent literature relating to the tendon healing and adhesion prevention.

Down syndrome (DS) is a genetic condition caused by the triplication of chromosome 21. Persons with DS exhibit pronounced muscle weakness, which also occurs in the Ts65Dn mouse model of DS. Oxidative stress is thought to be an underlying factor in the development of DS-related pathologies including muscle dysfunction. High-levels of oxidative stress have been attributed to triplication and elevated expression of superoxide dismutase 1 (SOD1); a gene located on chromosome 21. The elevated expression of SOD1 is postulated to increase production of hydrogen peroxide and cause oxidative injury and cell death...

PURPOSE: Intraarticular distal radius fractures are often treated with open reduction and internal fixation (ORIF) through a volar approach. This common approach, however, is technically demanding to restore the articular surface of the radiocarpal joint while respecting soft tissue integrity. The purpose of this video is to demonstrate the surgical technique of volar plate fixation of an intraarticular distal radius fracture. METHODS: A 32-year-old patient who sustained multiple injuries including an intraarticular distal radius fracture was treated with ORIF by a volar approach...

BACKGROUND: Midportion Achilles tendinopathy (AT) is a common overuse injury, usually requiring several months of rehabilitation. Exercise therapy of the ankle plantar flexors (i.e. tendon loading) is considered crucial during conservative rehabilitation. Alfredson's isolated eccentric and Silbernagel's combined concentric-eccentric exercise programs have both shown beneficial results, but it is unknown whether any of these programs is superior for use in clinical practice. Therefore, the primary objective of this study is to compare the effectiveness of both programs on clinical symptoms...
