Clinical and functional outcomes of the remplissage technique to repair anterior shoulder dislocation: average 7 years of follow-up.

PURPOSE: The purpose of this work is to report mid- to long-term clinical results, recurrence rates and instability following surgery to repair anterior dislocation of the shoulder by the remplissage technique. METHODS: This was a retrospective case series at a single center with patients with anterior shoulder instability that received surgery using the remplissage technique. Rowe questionnaire, instability complaints, recurrence episodes and return to sport were analyzed. RESULTS: Of all patients screened, 21 (92.3%) were enrolled and only 2 patients were lost to follow-up. The mean age of the patients at the time of surgery was 27.8y.o., and the mean number of dislocations before surgery was 3.2 episodes. The follow-up average was 83.8 months (range 28-126). No case of postoperative infection was observed. Two patients (9.5%) had recurrent shoulder instability and required reintervention after 18 and 48 months. The average final Rowe score was 92.9 (range 75-100). All patients that played sports before surgery returned to the sport, and 73.7% of them returned to the same activity level. CONCLUSION: The remplissage technique applied to repair anterior shoulder dislocation with humeral bone loss presents good results regarding clinical scores, shoulder stability and acceptable rates of return to sports, even in a mid- to long-term follow-up. LEVEL OF EVIDENCE: IV.

Plasma brain-derived neurotrophic factor is higher after combat training (Randori) than incremental ramp test in elite judo athletes.

Elite judo demands high levels of physical and psychological skills. The brain-derived neurotrophic factor (BDNF) may be of particular interest in sports medicine for its ability to promote neuroplasticity. We investigated the plasma BDNF before and after a judo training session (Randori) and the maximal incremental ramp test (MIRT) in athletes from the Brazilian national judo team and compared the results between both exercise stimuli and sexes. Fifty-six elite judo athletes were recruited who performed each task on a separated day. Anthropometric, physiological, athletic parameters, and plasma BDNF levels were measured before and after the tasks (Randori and MIRT). The groups presented similar anthropometric and physiological characteristics at baseline for the two tasks. All athletes reached maximal performance for the tasks. Plasma levels of BDNF increased significantly after Randori and MIRT for all subjects, both men and women. When comparing both exercise stimuli, a greater increase in BDNF was observed after Randori. There was no significant difference in the delta BDNF between sexes. Our findings indicate that training specificity of sport gestures influenced the increase of blood BDNF levels.

Scaphoid stress fracture in high-level gymnast: a case report.

We present the case of an 18-year-old high-level gymnast who sustained a stress fracture of the scaphoid associated with a distal radial epiphysiolysis. Clinical evaluation demonstrated decreased range of motion of the affected wrist and insidious pain on the snuffbox and tenderness on the distal radial physis. He was submitted to surgical treatment with scaphoid percutaneous fixation and radial styloid process in situ fixation. Clinical features improved, and he got back to competition 6 months after surgery without symptoms and with complete range of motion.
