Surgeons fixing scaphoid fractures need to be familiar with its morphological variations and their implications on safe screw placement during fixation of these fractures. Literature has limited data in this regard. The purpose of this CT-based study was to investigate scaphoid morphometry and to analyse the safe trajectories of screw placement in scaphoid. We measured the coronal and Sagittal widths of scaphoid in CT-scans of 60 patients using CT based data from 50 live subjects with intact scaphoid. Safe placements for screws with diameters of 1.7mm, 2.4mm, 3.5mm and 4mm were studied using trajectories with additional 2mm safety corridor.Introduction
Methods
T-cells are considered to play an important role in the inflammatory response causing arthroplasty failure. The study objectives were to investigate the composition and distribution of CD4+ T-cell phenotypes in the peripheral blood (PB) and synovial fluid (SF) of patients undergoing revision surgery for failed metal-on-metal (MoM) and metal-on-polyethylene (MoP) hip arthroplasties, and in patients awaiting total hip arthroplasty. In this prospective case-control study, PB and SF were obtained from 22 patients (23 hips) undergoing revision of MoM (n = 14) and MoP (n = 9) hip arthroplasties, with eight controls provided from primary hip osteoarthritis cases awaiting arthroplasty. Lymphocyte subtypes in samples were analysed using flow cytometry.Objectives
Methods
Modified posterior approach and its effect on stability and functional outcome in total hip arthroplasty. A retrospective comparative evaluation was done to assess the functional outcome and rate of dislocation in 233 hips (Group A) operated before 2007 by convention posterior approach and 567 hips (Group B) were operated by modified posterior approach.(2007–2011) In this modified posterior approach technique, 2–3 stay sutures (non-absorbale Nylon) are applied in the piriformis tendon, short external rotator and proximal part of Quadratous muscle. Then a conjoint- myocapsular sleeve is raised by starting cutting (with cautery) linearly over the capsule with adherent fibers of gluteus minimus to piriformis tendon, short rotators and part of quadratus to expose and dislocate the head. After inserting the definite prosthesis, upper part of sleeve (capsule, piriformis tendon) is sutured with same nonabsorbable Nylon at the lower part of tip of greater trochanter by passing through the bone with needle or by drilling the bone; lower part of the sleeve is tied with lateral trochanteric bone. Additional stability to repair was given by closing the tendinous part of the gluteus maximus by horizontal cross mattress sutures up its attachment to the proximal femoral shaft.Background:

Role of intra-articular Tranexamic acid in total knee replacement arthroplasty Prospective evaluation was done to see the effect of intra-articular Tranexamic acid on blood loss in 60 patients (120 knees) undergoing total knee arthroplasty. All the patients were operated by one surgeon with same technique by using same implants. Patients were randomly injected 1500 mg/20 ml of Tranexamic acid on one side of the knee only. Nothing was injected on the contra lateral knee. Evaluation was done for swelling and the amount of blood loss in the drain.Background:
Materials and methods
Is routine use of suction drain after joint replacement is justified. Prospective evaluation was done to compare the effects of postoperative suction drain in 56 patients with no postoperative drain in 56 patients, undergoing total knee arthroplasty at our institute. Patients having severe systemic diseases, disturbed liver function, obesity, unstable diabetes and coagulation disorders were excluded from the study. Comparative evaluation was done for the blood loss, no of units of blood transfusion, wound hematoma, wound healing, duration of hospital stay, pain and range of motions.Background:
