INJURY EPIDEMIOLOGY IN BEACH TENNIS: INCIDENCE AND RISK FACTORS.

Introduction: Due to the growing increase in beach tennis practice in Brazil and the lack of studies on the injuries that occur in this sport, it has become necessary to develop more research on the subject.

Objective: to identify risk and protection factors for injuries in beach tennis, in order to generate prevention strategies for musculoskeletal injuries.

Method: A cross-sectional epidemiological study, level 3 of evidence, was carried out through an electronic form with 698 Beach Tennis players, who answered questions about their relationship with the practice of the sport and occurrences of injuries.

Bridging versus Nonbridging Dynamic External Fixation of Unstable Distal Radius Fractures in the Elderly with Polytrauma: A Randomized Study.

 Despite the high prevalence of unstable distal radius fractures (DRFs), there is no consensus regarding the optimal method and treatment timing, especially for elderly patients with multiple associated injuries.  This study aimed to compare the grip strength achieved with two different methods for definitive dynamic external fixation of DRFs in elderly patients with polytrauma operated on within the first 24 hours.  In this prospective randomized trial, 35 patients were assigned to undergo definitive external dynamic fixation of DRFs using the nonbridging (group A) or bridging (group B) method.

Ulnar Lengthening/Reconstruction of Interosseous Membrane in Treatment of Osteochondroma.

Background:  We aim to measure the quality of life and clinical and functional outcomes of a patient who had undergone ligament reconstruction of the forearm interosseous membrane, using brachioradialis tendon more ulna distraction osteogenesis in treatment with multiple cartilaginous exostosis.

Case Description:  We present a 11-year-old boy with congenital deformity in his right, dominant forearm,Type IIb by Masada classification. Distraction of the ulna, resection of exostosis, and reconstruction of the distal part of the interosseous membrane was performed.

Femur lengthening with monoplanar external fixator associated with locked intramedullary nail.

Objective: This study aimed to demonstrate that the lengthening technique of an external fixator associated with locked intramedullary nail is an efficient method that decreases the duration of the external fixation and improves the rehabilitation period.

Methods: From January of 2005 to May of 2014, 31 patients with mean lower limb discrepancy of 5.31 cm were treated.

Experimental trial on surgical treatment for transverse fractures of the proximal phalanx: technique using intramedullary conical compression screw versus lateral compression plate.

Objective: To compare the mechanical parameters between two methods for stabilization through compression: 1.5 mm axial compression plate versus conical compression screw used as an intramedullary tutor.

Methods: Polyurethane models (Sawbone(®)) that simulated transverse fractures of the proximal phalanx were used.

Biomechanical study of the sacroiliac fracture fixation with titanium rods and pedicle screws.

Objectives: To assess biomechanically different fixations means of the sacroiliac joint with pedicle screws and to compare the traditional head height with reduced ones.

Methods: We used a polyethylene model representing the pelvic ring and simulated a unilateral sacroiliac dislocation. We set up three different constructions: 1) two screws attached to a rod; 2) two rods connected to two small head screws each; and 3) two rods connected to two average headed screws each.

Bone tissue repair in patients with open diaphyseal tibial fracture treated with biplanar external fixation or reamed locked intramedullary nailing.

Introduction: Open tibial fractures are usually caused by high-energy trauma. There is no consensus about the best treatment for these fractures. Biomechanical studies show that fixing on two planes approaches the rigidity of the bone, whereas the use of interlocking intramedullary nailing is widely used and reported to produce better therapeutic results in fracture healing.
