Hydrotherapy with hydrogen-rich water compared with RICE protocol following acute ankle sprain in professional athletes: a randomized non-inferiority pilot trial.

We analysed the effects of an experimental novel protocol of intensive hydrotherapy with hydrogen-rich water (HRW) on injury recovery in athletic men who suffered an acute ankle sprain (AAS) and compared it with a RICE protocol (rest, ice, compression, elevation). Professional athletes (age 23.7 ± 4.0 years; weight 78.6 ± 5.7 kg, height 182.5 ± 4.3 cm; professional experience 5.9 ± 3.9 years) who incurred AAS during a sport-related activity were randomly assigned immediately after the injury to either hydrogen group (n = 9) or a conventional RICE treatment group (n = 9). Hydrogen group received six 30-min ankle baths with HRW throughout the first 24 h post-injury, with hydrotherapy administered every 4 hours during the intervention period. RICE group stood off the injured leg, with ice packs administered for 20 min every 3 hours, with the injured ankle compressed with an elastic bandage for 24 hours and elevated at all possible times above the level of the heart. HRW was equivalent to RICE protocol to reduce ankle swelling (2.1 ± 0.9% vs. 1.6 ± 0.8%; P = 0.26), range of motion (2.4 ± 1.3 cm vs. 2.7 ± 0.8 cm; P = 0.60), and single-leg balance with eyes opened (18.4 ± 8.2 sec vs. 10.7 ± 8.0 sec; P = 0.06) and closed (5.6 ± 8.4 sec vs. 3.9 ± 4.2 sec; P = 0.59). This non-inferiority pilot trial supports the use of HRW as an effective choice in AAS management. However, more studies are needed to corroborate these findings in other soft tissue injuries.

Microsurgical anatomy of the extra-articular segment of middle genicular artery.

PURPOSE: Knowledge of the incompletely studied microsurgical anatomy of the extracapsular part of the middle genicular artery (MGA) could imply an educational value and clinical significance because of the possible risk of injury during knee surgery. METHODS: Thirty formol-fixed cadaveric lower limbs in full extension were dissected and used for the measurements of MGA parameters. A second group of measurements was performed on distal ends of 30 adult femurs. Two fresh injected cadaveric lower limbs were explored by means of multidetector computed tomographic angiography (MDCTA). RESULTS: The MGA originated from the popliteal artery (PA), facing the lateral half of the intercondylar fossa in 16 (53.4 %) specimens, together with the superior lateral genicular artery (SLGA) in ten (33.3 %) cases, or from the same point of origin with SLGA and superior medial genicular artery (SMGA) in 4 (13.3 %) cases. The MGA averaged 15.6 mm in length and 1.8 mm in the outer diameter. After its curved direction the MGA entered the posterior capsule. The average distances of the point of MGA entrance into the joint capsule were as follows: to the lateral femoral epicondyle it was 34.88 mm, to the medial femoral epicondyle 46.38 mm, 5.74 mm lateral to the posterior midline, with an average vertical distance to the femoral subcondylar plane of 28.73 mm. CONCLUSION: This detailed anatomical examination with measurements of the extracapsular part of a MGA could be of clinical importance and useful in knee surgery for the prevention of vascular injury of MGA and PA, as well as in radiological examination of the knee region.

Comparative Analysis of Complication Rates in Tibial Shaft Fractures: Intramedullary Nail vs. Ilizarov External Fixation Method.

Background: The external fixation (EF) Ilizarov method, shown to offer efficacy and relative safety, has unique biomechanical properties. Intramedullary nail fixation (IMN) is an advantageous alternative, offering biomechanical stability and a minimally invasive procedure. The aim of this study was to assess outcomes in patients undergoing tibia fracture fixation, comparing the Ilizarov EF and IMN methods in an early phase of IMN implementation in Serbia. Methods: This was a retrospective study including patients with radiologically confirmed closed and open (Gustilo and Anderson type I) tibial diaphysis fractures treated at the Institute for Orthopedic Surgery "Banjica'' from January 2013 to June 2017. The following demographic and clinical data were retrieved: age, sex, chronic disease diagnoses, length of hospital stay, surgical wait times, surgery length, type of anesthesia used, fracture, prophylaxis, mechanism of injury, postsurgical complications, time to recovery, and pain reduction. Pain intensity was measured by the Visual Analog Scale (VAS), a self-reported scale ranging from 0 to 100 mm. Results: A total of 58 IMN patients were compared to 74 patients who underwent Ilizarov EF. Study groups differed in time to recovery (p < 0.001), length of hospitalization (p = 0.007), pain intensity at the fracture site (p < 0.001), and frequency of general anesthesia in favor of intramedullary fixation (p < 0.001). A shorter surgery time (p < 0.001) and less antibiotic use (p < 0.001) were observed when EF was used. Additionally, we identified that the intramedullary fixation was a significant predictor of pain intensity. Conclusions: The IMN method offers faster recovery and reduced pain intensity in comparison to EF, while the length of surgery predicted the occurrence of any complication.

Acute patellar dislocation in adolescents: operative versus nonoperative treatment.

PURPOSE: The purpose of this prospective non-randomised study was to compare the efficacy of two opposed methods, operative and conservative. Our hypothesis was that if the method was selected correctly, on an individual basis, the results should be approximately equal. METHODS: The study included 37 adolescents aged between 12 and 16 years, with a mean follow up of 6.1 years. The presence of a significant loose body, confirmed by precise imaging, was the key for selecting operative or arthroscopic treatment. In both groups of patients, we evaluated functional knee scores and the incidence of residual patellofemoral disorders. RESULTS: We confirmed our hypothesis using the t-test to compare functional results and a test for comparison of proportions for incidence of residual disorders. There was no statistically significant difference (p=0.091) between operatively and conservatively treated groups with regard to functional results. The same statistical outcome emerged when comparing incidences of re-dislocation (p=0.854), or other major patellar instabilities (p=0.856), between the groups. CONCLUSIONS: The results obtained should not promote a non-operative method on the basis of lower risk, but do support an individual approach based on precise diagnosis and defined criteria.

Effectiveness of oral and topical hydrogen for sports-related soft tissue injuries.

BACKGROUND: Because hydrogen therapy has been found beneficial for the treatment of inflammation, ischemia-reperfusion injury, and oxidative stress in humans, it seems useful to evaluate the effects of exogenously administered hydrogen as an element in the immediate management of sports-related soft tissue injuries. The main aim of this pilot study was to examine the effects of 2-week administration of hydrogen on the biochemical markers of inflammation and functional recovery in male professional athletes after acute soft tissue injury. METHOD: During the 2013 season (from March to May), 36 professional athletes were recruited as participants and examined by a certified sports medicine specialist in the first 24 hours after an injury was sustained. Subjects were allocated to 3 randomly assigned trials in a single-blind design. Those in the control group received a traditional treatment protocol for soft tissue injury. Subjects in the first experimental group followed the same procedures as the control group but with additional administration throughout the study of oral hydrogen-rich tablets (2 g per day). Subjects in the second experimental group also followed the procedures of the control group, with additional administration throughout the study of both oral hydrogen-rich tablets (2 g per day) and topical hydrogen-rich packs (6 times per day for 20 minutes). Participants were evaluated at the time of the injury report and at 7 and 14 days after baseline testing. RESULTS: Oral and topical hydrogen intervention was found to augment plasma viscosity decrease as compared with the control group (P = 0.04). Differences were found for range-of-motion recovery between the 3 groups; oral and topical hydrogen intervention resulted in a faster return to normal joint range of motion for both flexion and extension of the injured limb as compared with the control intervention (P < 0.05). CONCLUSION: These preliminary results support the hypothesis that the addition of hydrogen to traditional treatment protocols is potentially effective in the treatment of soft tissue injuries in male professional athletes. Trial identification: Clinicaltrials.gov number NCT01759498.

[Chiari pelvic osteotomy in treatment of hip dysplasia].

Chiari pelvic osteotomy is a surgical procedure having been performed for almost sixty years in patients with the insufficient coverage of the femoral head. It is most frequently used in young patients with dysplastic acetabular sockets as a part of developmental hip dysplasia. Even though performance of the Chiari osteotomy is associated with positive therapeutical results, above all, its main goal is to delay inevitable degenerative changes. Original surgical technique has been modified and improved over time. Nevertheless, the basic idea has remained unchanged--increasing of the femoral head coverage by medial displacement of the distal partof the pelvis along with capsular interpositioning. Given the complexity of operation, the complication percentage is rather low. Chiari pelvic osteotomy has lost its actuality and importance during this past six decades. The role of Chiari pelvic osteotomy has been considerably taken over by other more efficient and more lasting surgical procedures. Nonetheless, Chiari pelvic osteotomy is still present in modern orthopedic practice, above all as,salvage" osteotomy.
