Osteochondroma of talus

Abstract

Background: Proximal Femoral Nail (PFN) provides tangible evidence for its usage in unstable pertrochanteric fractures. There are a veritable number of references which show that PFN by virtue of its intramedullary fixation reduces the tensile strain thereby mitigating implant failure. Ours is a prospective study done on 50 subjects to assess the outcome of PFN usage in unstable pertrochanteric fractures. Methodology: 50 patients with Jensen Michaelsen type III, IV, V intertrochanteric and reverse oblique fractures were included in the study. The reduction obtained intra operatively was assessed using the modified criteria of Baumgaertner. Follow up evaluations were done at 6, 12, 24 and 52 weeks thereafter. Clinical evaluation was done using the Mobility score of Parker and Palmer. Radiographic parameters like fracture union, screw slide and degree of varus collapse were also assessed. Statistical analysis was provided by Friedman test. Results: Jensen Michaelsen type IV was the most common pattern observed (44%). The mean pre-injury parker score was 8.4. Patients with reverse oblique fracture morphology, type V fractures and patients with osteoporosis were treated with Long PFN (19 cases). The mean operating time was 92 minutes (range 60 -180), and the mean blood loss during the surgery was 145 ml (range 100ml -320 ml). The reduction was good in 40 patients (80%) and acceptable in the rest. The average time taken for fracture union was 15 weeks. It was observed that patients reached their preoperative mobility score of Parker and Palmer by 6 months post-surgery which was statistically significant (χ2 = 217.642, p < .001). Discussion: Proximal Femoral Nailing is done through a minimally invasive approach not disturbing the fracture hematoma which is a vital in fracture consolidation. The biomechanics of intramedullary fixation in cases of destabilised medial cortex is optimised by medialization of the fulcrum point and resultant reduction of the bending moment with respect to proximal fixation. Fracture reduction was good in 80% cases and in 10 cases the reduction was acceptable with a mean varus malalignment of 13.2 degrees.The mean intraoperative blood loss of 145 ml in our series compares favourably with previously reported values in the literature. Most of the fractures in our series (66%) united by 12-14 weeks. The mean preoperative mobility score of Parker was 8.4, which was reached by patients on their 6 th postoperative month (p & lt; 0.001). Each period showed statistically significant improvement over the previous period as evident from the rank total of the scores and the critical ratio.

Exploring the Bilateral Comparisons of Articular Surfaces of Talus: An Observational Study at Tertiary Health Care Center in Pune City

“…However, it was nearly similar to the observations by Motagi et al [8] (Right=2.94 cm and Left=3 cm). The findings about trochlear transverse width (Right=2.55 cm and Left=2.40 cm) in the present study corroborated with the observations of Kumar S et al [5] in which reported values were 2.53 cm on the right side and 2.57 cm on the left side. In our study, the mean value of length of inferior anterior articular surface was 2.8 cm on the right side 1.72 cm on the left side.…”

“…In this study, the mean value of medial articular surface height (MASH) was 1.25 cm on the right side and 1.27 cm on the left side. Greater measurements (1.30 cm on both sides) were documented in the study conducted by Kumar S et al [5] However, LASH values in their study [5] (2.30 cm and 2.33 cm on right and left side respectively) almost matched with the present study findings. The inter-relationship between various parameters of articular surfaces of the talus needs to be evaluated in detail as it might be applicable to design talar and calcaneal screw placement procedures, manufacturing of prosthesis as well as biochemical studies.…”

“…In the present study, the articular surfaces of the talus were studied, and the baseline data was created to assist anatomists, surgeons and anthropologists to utilize this knowledge for betterment of community. The mean TAPL observed by Kumar S et al [5], Otag and Cimen [6] and Ari and Kafa [7] were slightly higher than the observation of the present study (Right=2.94 cm and Left=3.04 cm). However, it was nearly similar to the observations by Motagi et al [8] (Right=2.94 cm and Left=3 cm).…”

“…The TGA data of M‐CNCs demonstrates a four‐step decomposition profile, as shown in Figure 4d. The M‐CNCs showed a continuous 10 % weight loss from 33→166.5 °C, 11.2 % weight loss from 166.5→268.7 °C, 18.3 % weight loss from 268.7→331.7 °C, 11.8 % weight loss from 331.7→425.4 °C, and 10.1 % weight loss from 425→700 °C [43] …”

PP-CBW/m-LLDPE/micro-CaCO3 composite films manufactured from bumper waste by blown film extrusion

“…As one of the most important microfiller, CaCO3 has been widely used in polyolefins as filler because of its low price, commercial availability and substantial improvement in mechanical properties stemming from its spherical shape morphology. Also, due to its high thermal conductivity, CaCO3 shows high improvements in output and hence faster heating and cooling process cycles [9][10][11][12]. The surface of CaCO3 particles is hydrophilic and polar and to improve their applicability as fillers and their adhesion with a non-polar matrix such as olefins, these particles are usually treated with stearic acid.…”
