ABSTRACT Nicotine delays the healing process and increases the levels of myeloperoxidase (MPO), an enzyme that plays a key role in the production of reactive oxygen species during the inflammatory process. Laser Photobiomodulation (PBM) is one of the most used electrophysical agents in the treatment of the calcaneal tendon, however, its effects on MPO activity need to be further elucidated. This study aimed to evaluate the effects of laser PBM on MPO activity after inflicting an injury to the calcaneal tendon of rats exposed to cigarette smoke. Thirty-four male Wistar rats with 90 days of age were used. After 14 days of exposure to cigarette smoke, the animals were divided into three experimental groups: control group (CG, n=12), not submitted to injury or treatment; sham group (ShG, n=10), submitted to partial calcaneal tendon injury and laser PBM simulation; and laser PBM group (PBMG, n=12), submitted to partial calcaneal tendon lesion and treated with laser PBM within the first minute after injury. PBM decreased MPO activity levels in PBMG compared to ShG (CG: 1.38±0.69pg/ml; ShG: 3.78±1.09pg/ml; PBMG: 2.58±0.93pg/ml; p<0.005). In conclusion, applying laser PBM immediately after inflicting damage to the calcaneal tendon attenuates acute inflammatory activity in rats exposed to cigarette smoke.

SummarySpontanous rupture at the distal part of the gastrocnemius tendon (GT) is the second most common non-traumatic tendon injury in dogs, whereas the other strands of the common calcaneal tendon do not seem to have a predisposition to rupture. In order to discover why we investigated the common calcaneal tendons of 63 dogs microscopically and biomechanically. Both the gastrocnemius and superficial digital flexor tendon (SFT) had multiple low vascularized fibrocartilaginous areas within their distal course as opposed to regular parallel fibered areas in the proximal tendon areas. Biomechanical testing revealed that the distal sections in both tendons show a 50% and 70% lower tensile strength (Fmax/kg BW) than the proximal sections (p<0.01), respectively. On the contrary, tensile load (Fmax/mm2) only differed minimally between proximal and distal sections in both tendons (8% and 9%, respectively), whereas the tensile load of the distal gastrocnemius tendon is 35% lower than of the distal superficial flexor tendon (p<0.01). To the authors' knowledge, this is the first study to experimentally show that there are different biomechanical properties within the same tendon. The maximum load to failure is lower in the GT compared to the SFT within the same dog which explains its higher incidence of rupture in the field. The avascular fibrocartilaginous structure in the distal gastrocnemius tendon seems to play a further role in the pathogenesis of spontaneous rupture.

SummaryUltrasonography was prospectively evaluated as an ancillary diagnostic technique in canine common calcaneal injury in a series of six cases with surgical confirmation of the diagnosis. Preoperative sonographic examination localized the site of injury to the affected component of the common calcaneal tendon. Sonographic lesions consisted of focal disruption of normal tendon echotexture in all six cases, with slight to considerable enlargement of the affected tendon in five of the six cases. Sonographic examination detected the additional lesion of lateral displacement of the superficial digital flexor tendon in one case in which it was present. However, sonographic examination could not differentiate partial from complete tendon rupture.Ultrasonography was prospectively evaluated as an ancillary diagnostic technique in six cases of canine common calcaneal tendon injury with surgical confirmation of the diagnosis. The technique was useful in preoperative localization of the site of injury within the tendon, but differentiation of partial versus complete tendon rupture was not possible.

AbstractRecent epidemiological analyses in fencing have shown that injuries and pain linked specifically to fencing training/competition were evident in 92.8% of fencers. Specifically the prevalence of Achilles tendon pathology has increased substantially in recent years, and males have been identified as being at greater risk of Achilles tendon injury compared to their female counterparts. This study aimed to examine gender differences in Achilles tendon loading during the fencing lunge.Achilles tendon load was obtained from eight male and eight female club level epee fencers using a 3D motion capture system and force platform information as they completed simulated lunges. Independent t-tests were performed on the data to determine whether differences existed.The results show that males were associated with significantly greater Achilles tendon loading rates in comparison to females.This suggests that male fencers may be at greater risk from Achilles tendon pathology as a function of fencing training/ competition.

INTRODUCTION Rupture of extensor pollicis longus (EPL) tendon is a recognised complication following volar plate fixation of distal radius fractures, usually from attrition caused by prominent screws. We sought to identify the screw holes in some of the most commonly used plates which may precipitate tendon injury. SUBJECTS AND METHODS Three fixed-angle volar locking plates were sequentially positioned into 18 cadaveric arms. A wire was passed through each of the holes in the plates using a locking guide and the dorsal relationships noted. RESULTS Each plate had specific ‘high-risk’ holes which directed the wire towards the EPL groove. The central screw holes appeared mostly implicated in EPL injury. CONCLUSIONS Awareness of ‘high-risk’ holes and appropriate minor alterations in surgical technique may consequently decrease the incidence of EPL irritation and rupture.
