The epitrochleytis in the baseball pitcher
No full textAim. Aim of this study is to evaluate the efficaciousness of a programm aiming to prevent relapse of epitrocleytis. This overuse pathology being caused by repeated microtraumas on articular parts of the elbow during constant throwing in baseball game. Methods. Eighty-six baseball players, playing in professional and semiprofessional teams in the area of Parma underwent a screening. Nineteen pitchers were selected, the age varied from 18 to 25 years, who had lamented in the previous twelve months at least two episodes of testified epitrocleytis, none the less at the moment of selection they did not show any painful symptom. An isokinetic test was effected in order to verify the peak torque and power of pronator-supinator muscles, it showed an increase of peak torque and power of pronator muscles. It was well adviced a therapeutical programm to restablish singularly the deficitarious muscles by global reinforcement muscular exercises and specifically isotonic with weights and theraband. Results. The isokinetic test effected after six months from therapeutical preventive treatment underlined a variation statistically meaningful with a medium increase of the peak torque value of 24% and power of 19% for supinator muscles with an angular speed of 90°/sec.; respectively of 26% and 20.6% with angular speed of 180°/sec. A balanced equilibrium between pronator-supinator muscles was successfully achieved. No elbow pathology was present after two years treatment. Conclusion. The muscular unbalance may provoke pathologies in structures musculo tendinous and capsule-ligamentous in baseball game. The improvement of muscular balance resulted by the adviced treatment showed by isokinetic test, has positively influenced the biomechanic of the movement and we believe that was a relevant factor in preventing the frequent relapses. In all those sports in which throwing is particularly elicited, it was necessary a harmonic balance in the muscular structure in particular of pronator and supinator muscles; all this may be achieved by a suitable preventive exercise

Outcome of short versus conventional stem for total hip arthroplasty in the femur with a high cortical index: a five year follow-up prospective multicentre comparative study
No full textBackground: The uncemented total hip arthroplasty (THA) has become the choice for many hip surgeons. Although conventional uncemented femoral components have a proven track record, there remain concerns about the rate of thigh pain, proximal stress shielding, and consequent loss of bone stock at revision surgery. Methods: Inclusion criteria were the following: patients between 50 and 85 years old undergoing primary THA with implant of short (group 1) or conventional (group 2) femoral stem and with femoral shape type A, according to Dorr classification. Clinical follow-up was registered using OHS, HHS, and Womac scores. The radiographic scans were evaluated in order to compare component positioning and bone remodeling at five year follow-up. Results: We included in the analysis 60 subjects in group 1 and 67 in group 2. No differences were registered between the groups comparing demographic and operative data. One case in group 1 (1.7%) and three cases in group 2 (4.5%) reported an intra-operative fracture. There was a significant improvement in the functional scores in both groups with no significant difference at final follow-up. The incidence of reported thigh pain at follow-up was 14.9% in group 2 and 3.3% in group 1 (p = 0.033). Radiographic analysis documented a difference in terms of stress shielding and thinning of medial and lateral cortex in favour of group 1. Moreover, patients of group 1 showed a higher varus angle at six month follow-up. Conclusion: In patients with high cortical index, a short stem shows better clinical and radiological outcomes at five year follow-up

No full textTreatment of distal tibial fractures: prospective comparative study evaluating two surgical procedures with investigation for predictive factors of unfavourable outcome
No full textPurpose: The aim of this study is to compare clinical and radiological outcome of intramedullary nailing (IMN) and locked plate (LP) in patients affected by fracture of the distal tibia (DTF). We performed also an analysis to identify predictive factors of unfavourable outcome. Methods: Data about patients with DTF treated at our first level trauma centre between 2008 and 2017 were collected. Patients were divided in group 1 (IMN) and group 2 (LP). The inclusion criteria were age at least 18 years at the time of diagnosis and unilateral DTF (closed or Gustilo 1). Demographic variables and data related to surgical procedure and hospitalization were registered. X-ray at follow-up was reviewed to identify malunions and nonunions. Clinical outcome was evaluated using scores and registering any complication. Results: One hundred two patients were included in group 1 and 81 in group 2. In group 2 were documented higher operating time and hospitalization. The mean union time was 20.2 weeks for IMN and 24.8 weeks for LP group (p = 0.271). The rate of infections and wound complications was higher in group 2 while malunion and anterior knee pain were more frequent in group 1. No difference in scores for clinical outcome was documented after six months. The full-weight bearing time was significantly longer in the LP group (p = 0.019). At multivariate analysis, no variables showed a predictive power for unfavourable outcome. Conclusions: Clinical and radiological results of LP and IMN appear similar. No predictive factors of unfavourable outcome were identified

No full textGrice subtalar arthrodesis of bilateral adult flatfoot in a professional dancer: A case report
Full text linkBackground and aim: Adult acquired flatfoot deformity (AAFD) is a common pathology and an important cause of pain and disability. This deformity causes a progressive flattening of the foot arch which has traditionally been associated with posterior tibialis tendon (PTT) dysfunction. Operative treatment is indicated after the failure of conservative management aiming to achieve proper alignment of the hindfoot and to maintain as much flexibility as possible. If subtalar osteoarthritis is present, subtalar arthrodesis is usually the best therapeutic option. Grice-Green subtalar arthrodesis is a widely used procedure. Methods: This report describes a case of bilateral painful AAFD in a 39-years old female professional dancer treated with Grice-Green subtalar arthrodesis with an autologous corticocancellous graft harvested from the ipsilateral proximal tibia. Surgeries were performed 3 years apart from each other. Results: The patient had good clinical and radiological outcomes. She returned to dance 4 months after surgery with no referred pain or limitations. Conclusions: Due to its versatility and capability to restore the shape and thickness of the hindfoot Grice-Green procedure is a simple and effective technique for the treatment of AAFD with subtalar osteoarthritis and a valid option to solve professional disabilities as it happened in this case with a professional dancer.
