A prospective, randomized, controlled trial was performed to compare the outcome of treatment of unstable fractures of the proximal part of the femur with either a sliding hip screw or a short proximal femoral nail antirotation (PFNA-XS, Synthes).

Eighty one patients (April 2007 – May 2008) presenting with unstable fracture of the proximal part of the femur were randomized, at the time of admission, to fixation with use of either a short proximal femoral nail antirotation (n=42) or a sliding hip screw (n= 39). The primary outcome measure was reoperation within the first postoperative year and mortality at the end of one year. Operative time, fluoroscopy time, blood loss, and any intra-operative complication were recorded for each patient. Follow-up was undertaken at 3, 6, and 12 postoperative months and yearly thereafter. Plain AP and lateral radiographs were obtained at all visits. All changes in the position of the implant, complications, or fixation failure were recorded. Hip range of motion, pain about the hip and the thigh, walking ability score and return to work status were used to compare the outcomes.

There was no significant difference between 1 year mortality rates for the two groups. Mean Operative time was significantly less in PFNA group (Mean 25 min, range 19 – 56 min) than DHS group (Mean 38 min, range 28 – 70 min). Patients treated with a PFNA experienced a shorter fluoroscopy time and less blood loss. 6 patients in DHS group had implant failure as compared to none in PFNA group. The functional outcome was also better in PFNA group.

When compared to DHS, PFNA-XS provides better functional outcome for unstable trochanteric fractures with less operative time, less blood loss and less complications, however one year mortality rate remains the same.

A prospective, randomized, double-blind study was done on 50 patients undergoing primary cementless total hip arthroplasty to determine the effect of tranexamic acid on intra- and postoperative blood losses and on the transfusions requirements.

50 patients were randomized to tranexamic acid (15 mg/kg) given as a bolus intravenous injection or placebo (normal saline) given intravenously, 15 minutes before the incision.

The intraoperative and postoperative blood loss (at removal of the drain 24 hours after the operation) and the number of blood transfusions required were recorded. The patients were screened for deep venous thrombosis with bilateral compression Ultrasonography using Colour Doppler imaging on the tenth postoperative day. The Hemoglobin level was measured preoperatively and on the 3rd postoperative day. The D-dimer levels were measured preoperatively and 24 hrs postoperatively.

Patients receiving tranexamic acid had a mean intraoperative blood loss of 410 ml (range, 300–510 ml) versus 615 ml (range, 515–750ml) (p value<0.05) in patients receiving placebo, a postoperative blood loss of 210 ml(range, 150–325ml) versus 490 ml(range, 370–540ml) (p value<0.05), and a total need for 8 blood transfusions versus 30. Only 6 out 25 patients in tranexamic acid group required blood transfusion whereas 18 out of 25 patients in the placebo group required transfusion.

In the group receiving placebo the mean fall in hemoglobin was 2.9g/dl (range, 2.5–3.2) and in the group treated with tranexamic acid 1.6 g/dl (1.3–2) (p<0.05). At 24 hrs postoperatively, mean plasma D-dimer concentration in the Tranexamic group was half of that in the control group. No patient in either group had any evidence of deep vein thrombosis on bilateral compression Ultrasonography using Colour Doppler imaging done on the tenth postoperative day.

Tranexamic acid 15 mg/kg given as a single preoperative bolus dose reduces peroperative and postoperative and total blood loss, and transfusion requirements in primary cementless total hip replacement surgery without any increased risk of thrombus formation.

Adequate exposure is a prerequisite for treatment of distal humeral fractures. In this study, we compared the clinico-radiological and functional outcome of TRAP approach with that of olecranon osteotomy for distal humerus fractures.

27 patients with distal humerus fractures were randomized into 2 groups: Group 1 (n=14, TRAP approach), Group 2 (n=13, Olecranon osteotomy). All patients were operated with bi-columnar fixation. All patients were mobilized from day 2. Follow-up evaluation was done at 1, 3, 6 and 12 months.

All patients achieved union. The mean surgical time was higher in group 1 (120 min) as compared to group 2 (100 min). The final ROM was higher in group 1 (1160) as compared to group 2 (850). Two patients in group 2 needed posterior release. 5 patients in group 2 had hardware complications related to olecranon osteotomy and needed removal. Two patients in Group 1 had transient ulnar nerve paraesthesias. There was no difference in triceps power in both groups.

Our results demonstrate that TRAP approach is extensile and safe enough in treating these complex fractures with better final ROM and fewer complications.

Large femoral neck defects pose a great challenge for orthopedic surgeons and are frequently associated with neglected femoral neck fractures, post infective sequale and failed implants around femoral neck. We present our technique (AIIMS Box Technique) of neck reconstruction aiming to preserve the natural femoral head and restoring the function of hip in cases of large femoral neck defects.

A total number of 52 patients (age range 20 to 56 years with an average of 38 years) with large femoral neck defects were treated from January 1990 to May 1997 and were followed for a minimum of 10 years (range 10 to 17 years). Neck defect was converted into a box using osteal flaps (Base from greater trochanter, Anterior wall from head, Quadratus Femoris muscle pedicle graft posteriorly). This box was filled with cancellous bone autograft along with three cancellous screw fixation.

Union occurred in all patients in a mean time of 16 weeks (range 12–20 weeks). One patient in our series had avascular necrosis (AVN) of femoral head. Eighteen out of 52 results were classified as excellent, 28 good and 6 fair. No patient had poor result. Good functional mobility including squatting was seen in all but two patients. Complications included coxa vara in two patients, hardware problems in four patients.

Our study shows that large femoral neck defects can be managed successfully with preservation of vascularity of femoral head. This procedure can be considered an alternative to excisional or replacement arthroplasty, particularly in young adults.
