Clinical Suspicion

We present a bibliographic review and a description of the surgical technique in checkrein deformity of the hallux and lesser toes. This dynamic deformity causes a significant difficulty in walking and prevents patients from practicing any sport, since in the stance phase of gait toes are forced into maximum plantar flexion and end up trapped under the foot. In cases in which this is not associated with a bone fracture, the clinical suspicion causing the injury is a subclinical compartment syndrome. Treatment described in this work consists of a Z-plasty and the application of a pulvertaft suture in the flexor hallux longus. In the rest of the toes, any additional surgical procedure is not needed, as the deformity is corrected at the retromalleolar level.

SummaryAchilles mechanism rupture in four of five dogs was treated with tenorrhaphy using a modified surgical technique designed to optimise accurate apposition of tendon to bone. Two bone tunnels were drilled in the calcaneal tuber from a plantomedial - dorsolateral, and plantolateral – dorsomedial direction respectively. The distal ends of the tendons were sutured to the calcaneal tuber using a Krachow suture pattern. The remaining dog had a mid-tendon Achilles mechanism rupture. A resinous half cast was placed on the cranial aspect of the tarsocrural joint of all five dogs, for a minimum of six weeks, in order to provide limited post operative support. Du e to insufficient cast material two of the support splints failed and one of these cases also required a second surgical procedure. A varying amount of soft tissue irritation was noted in each case. All of the five Achilles mechanisms healed, and all of the dogs returned to normal function.Five dogs with surgical reconstruction of the Achilles mechanism were stabilised postoperatively with a resinous half cast placed on the cranial aspect of the tarsocrural joint for a minimum of six weeks. Two of these casts failed at the tarsocrural joint when six folds of casting material were used; all subsequent cases had eight folds applied. Variable soft tissue irration was observed under the cast in each case. A modified surgical technique using a Krachow suture pattern allowed good tendon-bone apposition. All five Achilles mechanisms healed, and all dogs returned to normal function. Bilateral lesions were identified in 3 of the 4 dogs examined.

The prevalence of dentoalveolar injuries in children is approximately 25%, with falls from own height being one of the main etiologies. Diagnosis is based on the clinical evaluation associated with complementary imaging tests. The treatment of choice depends on the type of damage and structure affected. For alveolar process fractures, closed reduction and semi-rigid dental splinting for 4 to 6 weeks is generally satisfactory. However, some cases, such as severe segmental fractures, require open treatment to ensure adequate reduction and stabilization of the displaced alveolar segment, which is usually achieved by titanium miniplates and screws. Nevertheless, there are situations where this type of fixation is not possible, requiring alternative methods. Therefore, this article describes a surgical technique performed by open reduction, associating semi-rigid dental splint and circummandibular wiring in pediatric patient diagnosed with dentoalveolar fracture through clinical examination (with bone fracture displacement) and tomography. The technique promoted a good prognostic to the patient, proving to be a viable alternative for treating dentoalveolar fractures.

Muscle Activations

This study analysed the landing performance and muscle activity of athletes in forefoot strike (FFS) and rearfoot strike (RFS) patterns. Ten male college participants were asked to perform two foot strikes patterns, each at a running speed of 6 km/h. Three inertial sensors and five EMG sensors as well as one 24 G accelerometer were synchronised to acquire joint kinematics parameters as well as muscle activation, respectively. In both the FFS and RFS patterns, according to the intraclass correlation coefficient, excellent reliability was found for landing performance and muscle activation. Paired t tests indicated significantly higher ankle plantar flexion in the FFS pattern. Moreover, biceps femoris (BF) and gastrocnemius medialis (GM) activation increased in the pre-stance phase of the FFS compared with that of RFS. The FFS pattern had significantly decreased tibialis anterior (TA) muscle activity compared with the RFS pattern during the pre-stance phase. The results demonstrated that the ankle strategy focused on controlling the foot strike pattern. The influence of the FFS pattern on muscle activity likely indicates that an athlete can increase both BF and GM muscles activity. Altered landing strategy in cases of FFS pattern may contribute both to the running efficiency and muscle activation of the lower extremity. Therefore, neuromuscular training and education are required to enable activation in dynamic running tasks.

Movement Differences

The objectives of this study were to determine the amplitude of movement differences and asymmetries between feet during the stance phase and to evaluate the effects of foot orthoses (FOs) on foot kinematics in the stance phase during running. In total, 40 males were recruited (age: 43.0 ± 13.8 years, weight: 72.0 ± 5.5 kg, height: 175.5 ± 7.0 cm). Participants ran on a running treadmill at 2.5 m/s using their own footwear, with and without the FOs. Two inertial sensors fixed on the instep of each of the participant’s footwear were used. Amplitude of movement along each axis, contact time and number of steps were considered in the analysis. The results indicate that the movement in the sagittal plane is symmetric, but that it is not in the frontal and transverse planes. The right foot displayed more degrees of movement amplitude than the left foot although these differences are only significant in the abduction case. When FOs are used, a decrease in amplitude of movement in the three axes is observed, except for the dorsi-plantar flexion in the left foot and both feet combined. The contact time and the total step time show a significant increase when FOs are used, but the number of steps is not altered, suggesting that FOs do not interfere in running technique. The reduction in the amplitude of movement would indicate that FOs could be used as a preventive tool. The FOs do not influence the asymmetry of the amplitude of movement observed between feet, and this risk factor is maintained. IMU devices are useful tools to detect risk factors related to running injuries. With its use, even more personalized FOs could be manufactured.

The incidence of medial sesamoid bone fracture is rare. Clinically they are often misdiagnosed as soft tissue injuries and often missed. Thus generates an important morbidity for the patient. Objectives: We present a case of turf-toe injury: plantar-plate rupture with medial sesamoid bone fracture in a contact athlete. Methods: A 19-year-old professional soccer player injured his left toe when he planted his foot during a sprint. He had an hyperextension and axial overload traumatism in his toe. On physical examination he had pain, swollen, ecchymosis, instability and loss of plantar-flexion strength. Radiographs showed a transverse medial sesamoid bone fracture with retraction > 3 mm. Magnetic resonance imaging confirmed a subluxation of the proximal phalange and a plantar plate disruption. Because of the completely deficient flexion, the sesamoid retraction, and the articular subluxation, surgery was recommended to restore the MTPJ anatomy. Reduction of the fracture and Repair of the plantar plate was performed using non-absorbable 2-0 Fiber wire sutures through a medial approach. Postoperatively, the patient was placed in a cast, for a total of 2 weeks. After that he began a rehabilitation program. Results: The patient had a complete recovery. He returned to participation in his team at 3 months. At final follow-up, his dorsiflexion ROM was 60 in the involved toe. Conclusion: Turf-toe and disorders of the sesamoid complex is an important injury, often misdiagnosed and usually undertreated. They had an incidence of 25% to 50% of residual pain and limited dorsiflexion in those cases. Despite the incidence of surgical treatment of 2%, we have found hopeful results with the open reduction and internal fixation of the fracture. Accurate and timely diagnosis and treatment can allow for full return to activity for these athletes.
