Smoking is a poor prognostic factor for healing after rotator cuff repair and is associated with inferior results. We hypothesized that smokers would have higher recurrent tear rates and more postoperative myotendinous junction (MTJ) retraction in healed repairs than nonsmokers three months postoperatively.

Rotator cuff repairs (RCRs) were retrospectively reviewed over a 2-year period. Patients underwent magnetic resonance imaging (MRI) within 6 months prior to surgery and again at 3 months postoperatively. Seventy-nine patients were included and stratified by smokers versus nonsmokers. Baseline patient demographics, tear characteristics, and surgical factors were collected. Preoperative and postoperative MRIs were assessed to quantify the MTJ position and to establish the recurrent tear rate.

For the total cohort (nonsmokers, n=56; smokers, n=23), significant differences in age, race, and traumatic onset of injury existed between groups. There were no significant differences in recurrent tear between sospective cohort study; Diagnostic study.

Treatment of distal radius fractures has seen a paradigm shift since the use of volar locking plates became popular. However, there is a subset of fractures, which includes extreme distal volar rim fractures, that is often not amenable to fixation by volar locking plates as there is insufficient bone mass to put screws. These fractures as such are quite rare but carry a huge morbidity due to frequent lack of anatomical reduction and fixation. A number of different techniques like hook plates, specially designed distal volar locking plates and loop wire techniques have been described for these fractures, but they have been found to be less helpful when the fracture fragments are very small.

Herein, we describe our experience on 6 patients, using a novel surgical technique for fixation of distal radius volar rim fractures which works equally well even when the fragments are quite small (2-3mm). The technique uses low cost and readily available implants (K wire and conventional volar locking plate) without t fracture fragments which can be easily adopted and used by surgeons in developing countries.
An anatomical double bundle ACL reconstruction replicates the anatomy of native ACL as the tunnels are made to simulate the anatomy of ACL with AM and PL bundle foot prints. The goal of anatomic ACL reconstruction is to tailor the procedure to each patient's anatomic, biomechanical and functional demands to provide the best possible outcome. The shift from single bundle to double bundle technique and also from transtibial to transportal method has been to provide near anatomic tunnel positions.

To determine the position of femoral and tibial tunnels prepared by double bundle ACL reconstruction using three dimensional Computed tomography.

A prospective case series involving forty patients with ACL tear who underwent transportal double bundle ACL reconstruction.

Computed tomography scans were performed on forty knees that had undergone double bundle anterior cruciate ligament reconstruction. Three-dimensional computed tomography reconstruction models of the knee joint were prepared and aligned into an aanterior and nearly proximal whereas the femoral PL tunnel was positioned significantly anterior and nearly distal with respect to the anatomic site. Location of tibial AM tunnel was nearly posterior and nearly medial whereas the location of tibial PL tunnel was very similar to the anatomic site Evaluation of location of tunnels through the anatomic co-ordinate axes method on 3D CT models is a reliable and reproducible method. This method would help the surgeons to aim for anatomic placement of the tunnels. It also shows that there is scope for improvement of femoral tunnel in double bundle ACL reconstruction through transportal technique.
It has been indicated in several instances that tall stature is also an important risk factor in the development of osteosarcoma. This relationship between height and osteosarcoma is substantiated even more by the increasing evidences being put forth in the recent literature on dependence of certain tumors on the growth factors and their receptors, acting through autocrine or paracrine mechanisms. There has been no study on the Indian population that attempts to define such a relationship.

The primary objective of this study was to define relationship between height of patients and osteosarcoma at the time of diagnosis in the Indian population.

Retrospective data was collected from the old hospital records. Height of patients at the time of diagnosis was compared with expected height of patients of the same age with reference to the standardized growth charts provided by the Indian Academy of Paediatrics.

Out of 98 patients, there were 65 male and 33 female patients with M F ratio being 1.971. The mea an important finding. https://www.selleckchem.com/products/6-diazo-5-oxo-l-norleucine.html It could be deduced from this observation that these patients are unable to mount the usual biological response to the overstimulated growth as part of tumorigenesis in osteosarcoma. This could point to a different scenario in the Indian population and more studies need to be carried out with larger number of patients to further elaborate on this observation.
As more evidence comes to light that hamstring harvesting may not be as benign a procedure as previously thought, considerable interest is being generated towards corelating the knee flexural strength deficits with the degree of tendon regeneration. The current study aimed to corelate knee flexion strength deficits with ultrasonographically quantified degree of hamstring regeneration after tendon harvest.

31 patients of ACL reconstruction with hamstring grafts were divided into 2 groups (6 months and 1-year post op) according to time of follow up. Ultrasonography of both the knees to assess Semitendinosus tendon dimensions was done. Regeneration was classified as non-significant, mild (Zone 1, till 4cm above the lateral joint line), moderate (Zone 2,at the level of the lateral joint line) and significant (Zone 3, 1.5cm below the lateral joint line) as the regenerate happens from proximal to distal. Regenerate dimensions were compared with US measurements from the opposite knee. Bilateral isokinetic strength tests of the knees were done to evaluate flexion strength, and strength deficits were compared with degree of tendon regeneration.
