Pojavnost ozljeda i oštećenja sustava za kretanje vrhunskih veslača

There is no information about injuries among international rowers and especially about the injuries among junior and master rowers. The aims of this research were to establish the associations between the occurrence of injuries among elite level rowers and their examined specifics. After the approval of Ethics Committees, 398 junior, 634 senior and 743 master rowers who have competed at 2007 World Rowing Championships (WRC) were interviewed. There were a total of 1775 participants from 70 countries. Rowing is a sport with low risk of injuries per training among rowers who sustained between 1.75 and 2.25 injuries/1000 training sessions/rower. High average number of training per a week caused that more than 50.0% of elite junior and senior rowers have been injured during the observed rowing season. The predominant injuries were overuse injuries of low severity. Low back injuries were the most frequent complaint. Senior rowers who were injured during the observed rowing season compared to those without injuries were significantly older, longer practiced rowing, competed at junior WRC, competed in “A” finals and won medals at previous senior WRC, and achieved significantly better final ranking at current senior WRC. The results of this research that junior rowers who were acutely injured during the on-water training had rowed for a shorter time compared to the rowers who did not sustain such injuries and that the higher incidence of chronic injuries was associated with higher average number of rowing trainings among junior and senior rowers have confirmed the hypothesis of this research that acute injuries are negatively associated with experience while chronic injuries are positively associated with the frequency of trainings

Ganglijske ciste koljena – retrospektivni prikaz niza uzastopnih slučajeva

The aim of this study was to describe relevant medical history, clinical symptoms and outcomes in 12 patients having undergone surgical treatment of intra-articular ganglion cysts of the knee at our Department from January 2010 to June 2016. Patient demographics, medical history, knee manifestations, management and outcome were evaluated. The mean patient age was 26.4 (range, 16-46) years. Th ere were seven female and five male patients. Duration of symptoms prior to the operation varied from 2 months to 3 years (mean, 17.1 months). All patients had preoperative magnetic resonance imaging work-up of the knee. Pain was the most common clinical presentation. All patients were surgically treated arthroscopically, and an additional open approach was used in only one of the patients. There were no complications during surgery and the postoperative period was uneventful in all patients. The mean follow up period was 43.5 (range, 9-83) months and no recurrence was observed. All patients remained symptom-free with full range of motion at final follow up. Despite a wide range of intra-articular ganglion cyst presentations and symptoms, our cohort demonstrated an excellent remission rate and functional prognosis following surgical treatment of the ganglion cysts of the knee.Cilj ovoga istraživanja bio je prikazati rezultate kirurškog liječenja simptomatskih ganglijskih cista smještenih unutar koljena. U razdoblju od siječnja 2010. do lipnja 2016. godine 12 je bolesnika (7 žena i 5 muškaraca) operirano u Klinici za ortopediju KBC-a Zagreb i Medicinskog fakulteta Sveučilišta u Zagrebu. Srednja životna dob u trenutku kirurškog zahvata bila je 26,4 (raspon, 16-46) godine. Srednje trajanje simptoma prije zahvata bilo je 17,1 (raspon, 2-36) mjeseci. Bol je bila vodeći simptom u bolesnika, a prije zahvata u svih je bolesnika načinjena i magnetska rezonanca koljena koja je uz dijagnostičko značenje pomogla i u planiranju artroskopskog zahvata. Kod svih je bolesnika nakon detaljnog artroskopskog pregleda koljena standardnim artroskopskim pristupima locirana ganglijska cista te je nakon uzimanja komadića tkiva za patohistološku analizu u 11 bolesnika u potpunosti resecirana uz pomoć motoriziranog instrumenta, dok je u jednog bolesnika zbog lokalizacije i veličine ciste bilo potrebno načiniti otvorenu eksciziju. Svi su kirurški zahvati, kao i rano poslijeoperacijsko razdoblje, protekli bez komplikacija. Srednje vrijeme praćenja bolesnika bilo je 43,5 (raspon, 9-83) mjeseci, a u tom se razdoblju nije pojavio recidiv niti kod jednog bolesnika. Na posljednjem kontrolnom pregledu svi su bolesnici bili bez simptoma uz pun opseg kretnja operiranog koljena. Ovo je istraživanje pokazalo da se, usprkos različitim prezentacijama simptomatskih intraartikularnih ganglijskih cista koljena, kirurškim liječenjem postižu odlični rezultati i potpun funkcionalni oporavak koljena u bolesnika

Osteochondritis dissecans of the elbow: excellent mid-term follow-up results in teenage athletes treated by arthroscopic debridement and microfracture

AIM: To evaluate the outcome of patients who underwent microfracture procedure on osteochondritis dissecans (OCD) lesions in the elbow, which had already been proven successful on OCD lesions in the knee and ankle. ----- METHODS: Nine young patients who were previously treated by arthroscopic debridement and microfracture by a single surgeon were included in the study. The median age at operation was 15 years (range 12-19). The median time between the procedure and evaluation was 5 years (range 2-9). The evaluation included physical examination and patient interview with elbow function scoring. Success of treatment was determined according evaluation Mayo Elbow Performance Index scores and the patients' return to sports. ----- RESULTS: Eight patients scored excellent results and 1 scored a good result. Four out of 9 patients were able to increase their training intensity, 2 returned to the same level of activity, 2 changed sports (due to reasons unrelated to the health of their elbow), and 1 left professional sports and started training only recreationally. No patients stopped participating in sports altogether. ----- CONCLUSIONS: We advocate arthroscopic microfracturing, followed by a strict rehabilitation regime, as a highly effective treatment for OCD of the humeral capitellum

Rib stress fracture in a male adaptive rower from the arms and shoulders sport class: case report

Adaptive rowing is rowing or sculling for rowers with a physical disability. It debuted at the Paralympic Games in 2008. In order to ensure an equitable playing field, rowers with similar levels of physical function and disability are classified into different sport classes for competition. Rowers with an inability to use a sliding seat and impaired trunk function resulting in an inability to perform trunk forward and backward lean via hip flexion/extension are assigned to the Arms and Shoulders (AS) class. AS rowers have to use a chest strap set immediately below the chest in order to localize any trunk movement in AS class. Conditions created by adaptations of rowing equipment and technique within the AS class create unique stresses on the upper thoracic region. The following case report demonstrates how etiology and management of a rib stress fracture in an AS rower differs in comparison to able-body rowers. Of significant importance were the limitations imposed on the rower’s ability to maintain rowing-specific fitness, due to the nature of the rib stress fracture and requirement to decrease force transmission through the ribs for several weeks. The rower’s gradual return to full training was further impacted by obligatory use of the chest strap, which directly applied pressure over the injured area. Protective orthosis for the chest was designed and applied in order to dissipate pressure of the chest strap over the thorax during rowing (most importantly at the catch position) both on the ergometer and in the boat

PERONEAL TENDONS DO EXIST, DON’T THEY?

Važan, ali vrlo često zanemarivan uzrok pojave boli u posterolateralnom dijelu gležnja i lateralnom dijelu stopala jesu ozljede i/ili oštećenja peronealnih tetiva. Ako se te ozljede i/ili oštećenja ne prepoznaju i ne liječe, dovode do pojave perzistirajuće boli i znatnih funkcionalnih teškoća. Cilj ovog rada jest dati uvid u regionalnu anatomiju i osvrt na kliničku sliku, kao i opisati trenutačne metode dijagnosticiranja i liječenja nekih češćih ozljeda i oštećenja peronealnih tetiva te upozoriti koje se metode kirurškog liječenja danas savjetuju. U radu se detaljnije osvrće na luksaciju peronealnih tetiva, subluksaciju peronealnih tetiva unutar omotača, tendinopatiju peronealnih tetiva, rupturu peronealnih tetiva te na bolni sindrom peronealne kosti.Peroneal tendon disorders are a significant but often overlooked cause of posterolateral ankle and lateral foot pain. When left untreated, peroneal tendon disorders can lead to persistent pain and substantial functional problems. The goals of this review are to develop a current understanding of the regional anatomy, as well as diagnostic evaluation and current treatment options of the peroneal tendon disorders, and to present nowadays preferred surgical techniques for operative management of peroneal tendon disorders. More specific details related to peroneal tendon luxation, intrasheath subluxation of peroneal tendons, peroneal trendinopathy, peroneal tendon tears and painful os peroneum syndrome are reported in this review article
