BackgroundWe aimed to establish values and parameters using multislice reconstruction in axial computerized tomography (CT) in order to quantify the erosion of the glenoid cavity in cases of shoulder instability.MethodsWe studied two groups using CT. Group I had normal subjects and Group II had patients with shoulder instability. We measured values of the vertical segment, the superior horizontal, medial and inferior segments, and also calculated the ratio of the horizontal superior and inferior segments of the glenoid cavity in both normal subjects and those with shoulder instability. These variables were recorded during arthroscopy for cases with shoulder instability.ResultsThe mean values were 40.87 mm, 17.86 mm, 26.50 mm, 22.86 mm and 0.79 for vertical segment, the superior horizontal, medial and inferior segments, and the ratio between horizontal superior and inferior segments of the glenoid cavity respectively, in normal subjects. For subjects with unstable shoulders the mean values were 37.33 mm, 20.83 mm, 23.07 mm and 0.91 respectively. Arthroscopic measurements yielded an inferior segment value of 24.48 mm with a loss of 2.39 mm (17.57%). The ratio between the superior and inferior segments of the glenoid cavity was 0.79. This value can be used as a normative value for evaluating degree of erosion of the anterior border of the glenoid cavity. However, values found using CT should not be used on a comparative basis with values found during arthroscopy.ConclusionsComputerized tomographic measurements of the glenoid cavity yielded reliable values consistent with those in the literature.

“…The baseline was drawn through A and B points, and two perpendicular lines drawn to the BL: W line from the BL: and H line from the lateral edge of the femoral head, passing through CH to BL (Figure 3). The ratio between H and W is defined as head wall index [10] . The timing of relocation was calculated as the time interval between the injury time and reduction of the joint The mean duration from fracture dislocation to surgery was 4 days with range from 2 to 12 days.…”

Background: Fracture dislocation of the hip is an absolute orthopaedic emergency which is increasing day by day. There are various factors determining the functional outcome in these patients. The aim of the study is to critically analyse various prognostic factors and effect of acetabular fracture index (AFI), posterior acetabular arc angle (PAAA), head wall index (HWI) on functional outcome as well as importance of timing of relocation in development of degenerative arthritis. Materials and methods: It is a prospective study including 23 patients, above 20 years of age with study period from January 2015 to May 2018. All the patients were evaluated clinically using modified Merle d` Aubigne Postel score and radiologically by Matta et al. criteria. The average follow up period was 2 ½ years. Results: 48% of cases had excellent outcome, 31% of cases had good and 13% of cases had fair outcome. 8% of cases end with poor outcome. The quality of reduction was anatomical in 61% of cases and imperfect in 30% of cases and poor in 9% of cases. The functional outcome was good in patients with higher value of acetabular fracture index, posterior acetabular arc angle and lesser head wall index. Conclusion:The quality of reduction of fracture remains the most important factor when compared to AFI, PAAA, HWI in determining the functional outcome. The timing of relocation of hip may be of less significance in fracture dislocation.

“…Several factors were suggested to influence strength and muscle activation, such as emotional and cognitive [ 1 - 4 ]. In order to achieve a maximum human potential in sports and to develop new techniques and to improve rehabilitation, the use of stimuli such as visual and verbal encouragement are used to develop at the best progression [ 5 , 6 ].…”

BackgroundCoactivation may be both desirable (injury prevention) or undesirable (strength measurement). In this context, different styles of muscle strength stimulus have being investigated. In this study we evaluated the effects of verbal and visual stimulation on rectus femoris and biceps femoris muscles contraction during isometric and concentric.MethodsWe investigated 13 men (age =23.1 ± 3.8 years old; body mass =75.6 ± 9.1 kg; height =1.8 ± 0.07 m). We used the isokinetic dynamometer BIODEX device and an electromyographic (EMG) system. We evaluated the maximum isometric and isokinetic knee extension and flexion at 60°/s. The following conditions were evaluated: without visual nor verbal command (control); verbal command; visual command and; verbal and visual command. In relation to the concentric contraction, the volunteers performed five reciprocal and continuous contractions at 60°/s. With respect to isometric contractions it was made three contractions of five seconds for flexion and extension in a period of one minute.ResultsWe found that the peak torque during isometric flexion was higher in the subjects in the VVC condition (p > 0.05). In relation to muscle coactivation, the subjects presented higher values at the control condition (p > 0.05).ConclusionWe suggest that this type of stimulus is effective for the lower limbs.
