We performed a prospective, randomized controlled study on 60 patients with fresh closed diaphyseal tibial fractures to determine the effect of percutaneous autologous bone marrow injection on union rate. Sixty patients were randomized into a group of 30 patients each. 30 patients were treated with reamed intramedullary interlocking nail and 30 patients were treated with combination of reamed i...

We carried out 71 primary total hip arthroplasties using porous-coated, hemispherical press-fit Duraloc '100 Series' cups in 68 consecutive patients; 61 were combined with the cementless Spotorno stem and ten with the cemented Lubinus SP II stem. Under-reaming of 2 mm achieved a press-fit. Of the 71 hips, 69 (97.1%) were followed up after a mean of 2.4 years. Migration analysis was performed by...

To the Editor:—In their article, Kato et al. report about intraoperative transesophageal echocardiographic findings in 46 patients who underwent total knee arthroplasty, randomly assigned with or without a tourniquet around the thigh. The authors looked for abnormal echogenic findings in the right atrium during the tourniquet inflation phase, and they sought to identify the nature and compositi...

& Minimum Quantity Lubrication (MQL) machining involves the application of a minute amount of an oil-based lubricant to the machining process in an attempt to replace the conventional flood coolant system. Understanding the correlations between fluid properties and MQL performance can help in selecting lubricants from a variety of choices without going through extensive machining tests. This st...

INTRODUCTION Osteopetrosis introduces technical limitations to the traditional treatment of fracture management that may be minimised with specific pre-operative planning. Extreme care and caution are required when drilling, reaming, or inserting implants in patients with osteopetrosis. Caution must be exercised throughout the postoperative course when these patients are at greatest risk for de...

Current arthroscopic suture fixation techniques of tibial eminence fractures are time consuming and the number of anchor sutures that can be placed is limited by the cumbersome and repetitive numerous needle threading steps. This occurs at 2 stages: first, when placing anchoring sutures through the avulsed anterior cruciate ligament stump with a suture punch, and second, when there is a need to...

Study Design: Prospective consecutive series. Objective: To Evaluate the role of exchange nailing in non union of fractures of long bones of lower limb. Summary of Background data: Exchange Nailing which includes removal of current intramedullary nail, reaming of medullary canal and placement of larger diameter nail shows increased union rate as seen in various studies. Methods: A Prospective s...

We report two cases of reamer breakage during femoral nailing. This complication is rarely reported, we found only six cases. It is an unexpected perioperative complication experienced by the authors as a stressful or catastrophic situation. In our first case, a flexible reamer was broken at the distal end while reaming the femur. The olivary tip of the guide was helpful to extract it. In the s...

PURPOSE To study clinical and mechanical factors that predispose to failure of interlocking nails. METHODS Between October 1996 and December 2002, 286 femoral fractures, 211 tibial fractures, and 47 humeral fractures were repaired using variously designed interlocking nails. Fracture pattern, level and site, nail size and type, weight bearing after nailing, and union status were reviewed afte...

Surgeons want to perform a perfect total hip arthroplasty (THA) with every operation. Human performance has limitations, especially when performing a mechanical operation in a biological environment. Recent suggested changes to improve outcomes have been large femoral heads and anterior incisions, but unfortunately, neither has resulted in any scientific data that change has been effected. The ...
