BackgroundPole sports, such as pole dancing, are recently gaining popularity as a form of fitness, combining dance and acrobatics. Many new, recreational athletes are joining pole sports every year. According to the international pole sports federation, this emerging new sport is so popular that it could be a future olympic sport.ObjectiveThe aim of this study is to describe the epidemiology of injuries in recreational athletes of pole sports, who were referred to the emergency demartment of our hospital.DesignThis a retrospective, case-series study based on hospital records, collected between December 2015 and July 2016.SettingThe study took place in the department of orthopaedic surgery, of the general hospital of karditsa, a provincial hospital in central Greece.Patients (or Participants)The study included all recreational athletes who were presented to our emergency department, due to injuries occured while performing pole dancing. 34 patients were finally included.Main Outcome MeasurementsThe primary study outcome is the epidemiology of injuries in pole sports.ResultsOverall, 29.4% of patients suffered from low back and hip, strains and contusions, 20.6% suffered from knee sprains and contusions, 17.7% suffered from wrist sprains, 14.7% suffered from ankle sprains, 5.9% suffered from neck (cervical spine) strains, 5.9% suffered from concussion, 1 patient (2.9%) presented with a sizable disc herniation and 1 patient (2.9%) presented with a fracture of the fifth metatarsal bone.ConclusionsAs pole sposts become more and more popular every year, injuries occuring during performance of this demanding activity are increasing. Sprains, strains, and contusions are the most frequent but more severe injuries such as concussions and fractures are also present due to falls from the pole. Studies with bigger samples are required in order to define the epidemiology of injuries in this new, emerging sport.
Purpose: To assess the anthropometric dimensions of the coracoid process and the glenoid articular surface and to determine possible implications with the different commercially available Latarjet fixation techniques. Methods: In a total of 101 skeletal scapulae the glenoid length (GL), the glenoid width (GW), the coracoid length (CL), the coracoid width (CW) and the coracoid thickness (CTh) were measured. In order to assess the ability of the transferred coracoid to restore the glenoid anatomy we created a hypothetical model of 10%, 15%, 20%, 25% and 30% glenoid bone loss. We analyzed four common surgical fixation techniques for the Latarjet procedure (4.5 mm screws, 3.75 mm screws, 3.5 mm screws, and 2.8 mm button). The distances from the superior-inferior and mediolateral limits of the coracoid using the four different fixation methods were calculated. We hypothesized that the "safe distance" between the implant and the coracoid osteotomy should be at least equal to the diameter of the implant. Results: The intra and inter-observer reliability tests were almost perfect for all measurements. The mean GH was 36.8 ± 2.5 mm, the GW 26.4 ± 2.2 mm, the CL 23.9 ± 3 mm, the CW 13.6 ± 2.mm, and the mean CTh was 8.7 ± 1.3 mm. The CL was < 25 mm in 46% of the cases. In cases with 25% and 30% bone loss, the coracoid graft restored the glenoid anatomy in 96% and 79.2% of the cases. With the use of the 4.5 mm screws the "safe distance" was present in 56% of the cases, with the 3.75 mm screws in 85%, with the 3.5 mm screws in 87%, and with the 2.8 mm button in 98% of the cases. The distance from the medio-lateral limit of the coracoid could be significantly increased (up to 9 mm) when smaller-button implants are used. Conclusions: The coracoid graft could not always restore glenoid defects of 30%. Larger implants could be positioned too close to the osteotomy and the "medio-lateral offset" of the coracoid could be increased with smaller implants.
Non-union of radial neck fractures is a rare entity in adults, and conservative treatment is usually applied. However, when the patient is symptomatic, an optimal functional outcome can only be obtained after operative treatment. There is currently no consensus on the best surgical technique to treat this condition. We present a 34-year-old male with a radial head non-union and our proposed technique of using a cylindrical bone autograft harvested from the iliac crest and fixation with headless compression screws. At 12 months follow-up, the patient was pain free and had comparable range of motion to the uninjured side. We recommend a useful technique for the treatment of radial neck fracture nonunion. The preliminary postoperative outcomes show excellent results, while a longer follow-up and a greater number of cases are necessary to confirm the efficacy of this technique.
