Profunda femoris artery injury caused by lesser trochanter fragment in intertrochanteric fracture: A case report.

Vascular injuries following intertrochanteric fracture have been sporadically reported. Despite its rare occurrence, this complication can be potentially life and limb threatening. The authors report an unusual presentation of false aneurysm of profunda femoris artery following an intertrochanteric fracture with marked displacement of lesser trochanter fragment.

Using a reconstruction locking compression plate as external fixator in infected open clavicle fracture.

Open clavicle fracture is an uncommon injury mostly caused by severe direct trauma. It is often associated with multiple organ injuries. Generally, surgical intervention with debridement and fracture repair is always indicated in order to prevent infection, non-union, and malalignment.

Biomechanical evaluation of fractured tibia externally fixed with an LCP.

A locking compression plate (LCP) can serve as an external fixation for fractured tibia. However, there is concern about the stability and endurance during partial weight bearing. This study was experimentally evaluated the effects of fracture gap sizes (1, 5, and 10 mm) on the stability and endurance of fractured tibia externally fixed with a 316L-stainless LCP.

Stiffness and endurance of a locking compression plate fixed on fractured femur.

The effects of locking screw position (long column fixation--long distance between the nearest screws to the fracture--and short column fixation--short distance between the nearest screws to the fracture) and fracture gap size (1-mm and 8-mm transverse fracture gap) on stiffness and fatigue of fractured femur fixed with a locking compression plate (LCP) were biomechanically evaluated. The stiffness of 1-mm fracture gap models and that of intact femoral model were in the range of 270-284 N/mm, while those of 8-mm fracture gap models were significantly lower (155-170 N/mm). After 1,000,000 cycles of loading, no fracture of LCP of 1-mm fracture gap models fixed in either long column or short column fashions occurred.

The effectiveness and safety of intra-articular injection of sodium hyaluronate (500-730 kDa) in the treatment of patients with painful knee osteoarthritis.

Background: Sodium Hyaluronate (500-730 kilodalton (kDa); Hyalgan) is recommended to administer intra-articularly once a week for 3-5 weeks in patients with osteoarthritis of the knee which its efficacy has been shown, from many clinical studies, to persist for at least 6 months. However only a few studies were done in Thai patients.

Objective: To assess the efficacy and safety of intra-articular Sodium Hyaluronate, administered once a week for four weeks (four injections) in Thai patients with painful Tibio-Femoral osteoarthritis of the knee over a six-month period.
