A biomechanical study of locking spongious screws and failure rates are higher than expected in plate fixation.

Locking plates have a rapidly growing process especially in the past decades and results are satisfactory especially in the osteoporotic bones compared to non-locking compression plates. There are many forms of failure in the fracture fixation of locking plates, and screw pull-out is one of the main failure reasons. In this study, we aim to investigate pull-out failure in locking plates using locking spongious screws.

A novel model of locking plate and locking spongious screw: a biomechanical in vitro comparison study with classical locking plate.

Background: Locking plates are commonly used for the fixation of comminuted, periprosthetic and osteoporotic bone fractures. These plates are secured to the bone with screws, creating a stable connection with fixed angle between the plate and the screws. In this biomechanical in vitro study, our aim is to evaluate and compare the novel locking plate-locking spongious screw model with FDA approved classical locking plate.

Treatment of osteonecrosis of the femoral head with free vascularized fibular grafting: Results of 7.6-year follow-up.

Objectives: The aim of this study was to determine long term follow up of the patients who had femoral head osteonecrosis and had been treated with free vascularized fibular grafting.

Patients And Methods: We retrospectively reviewed 28 hips of 21 patients who had undergone free vascularized fibular grafting for the treatment of osteonecrosis of femoral head. There were 16 male and 5 female patients.

Surgical Treatment of Lateral Malleolar Fractures Using the Compression Cerclage System.

Background Lateral malleolar fractures (Weber type B or OTA 44-B) account for 60% of all ankle fractures. To achieve anatomic restoration, surgical stabilization provides better results than conservative treatment. Various fixation methods are available to treat these fractures; however, the best method is still unknown.

Treatment of osteonecrosis of the femoral head with free vascularized fibular grafting: results of 7.6-year follow-up.

Objective: The aim of this study was to determine long-term follow-up results of patients with femoral head osteonecrosis who were treated with free vascularized fibular grafting (FVFG).

Methods: The results of 28 hips of 21 patients (16 male, 5 female) who underwent FVFG for treatment of osteonecrosis of the femoral head were retrospectively reviewed. Mean age of patients at time of surgery was 30.

Distraction lengthening of the proximal phalanx in distal thumb amputations.

Objective: Thumb amputation is a major cause of hand dysfunction, and the treatment for distal thumb amputations remains controversial. Although finger reconstruction methods using distraction lengthening are known to restore finger length and function, we found no reports in the literature regarding phalangeal lengthening in thumb amputations. We aimed to evaluate proximal phalangeal lengthening in thumb amputations at or near the interphalangeal (IP) joint.

Acute emergency tibialization of the fibula: reconstruction of a massive tibial defect in a type IIIC open fracture.

Gustilo type IIIC open fractures of the tibia are high-energy injuries necessitating long treatment periods and usually multiple surgical procedures and eventually resulting in high morbidity rates and even amputations. We present here a case involving a type IIIC open tibial fracture with massive loss of the entire tibial diaphysis, which we treated by performing acute tibialization of the fibula after revascularization of the posterior tibial artery in a single-stage emergency operation.

Trigger finger at the carpal tunnel level: three case reports.

Although trigger finger occurs mostly due to a problem at the A1 pulley various other causes have also been reported. We present three patients with different tumors at the carpal tunnel as a cause of triggering. All patients were treated with local excision.

Functional results of limb salvage in below-knee type III C open fractures or traumatic amputations.

This study presents the surgical and functional outcomes of below-knee total leg amputation and Gustilo type III C open fracture cases that were considered appropriate for salvage treatment according to a more proactive approach, despite being candidates for amputation according to the current scoring systems. Nineteen patients (21 legs) underwent replantation-revascularization surgery. At least Chen Grade II functional level was the aim.

Lengthening of a thumb distal phalanx replanted to its metacarpus because of loss of the proximal phalanx: case report.

We report a successful thumb replantation by resecting the remnants of the crushed proximal phalanx and uniting the distal phalanx with the thumb metacarpal. The procedure resulted in extreme shortening, which we managed by distraction lengthening and deepening of the first webspace.

Massive subcutaneous emphysema and pneumomediastineum after finger subtotal amputation with barotrauma.

Background: Advancement of pressurized air through subcutaneous tissue after barotraumas involving skin laceration has been documented in the literature. The type and anatomic location of injury, amount of pressure, and time elapsed all play a role in determining the destination of the air advancing through tissues.

Objectives: To report a case demonstrating the vascular system as the anatomic pathway for subcutaneous pressurized air resulting from an industrial accident.

[Lengthening of the phalanges by callus distraction in traumatic amputations of the fingers].

Objectives: We evaluated the results of lengthening of the phalanges by callus distraction in traumatic amputations of the fingers.

Methods: We treated traumatic amputations of 16 fingers of 13 male patients (mean age 27.7 years; range 12 to 43 years) by callotasis of the phalanges.

Role of side branches in determining suitable arterial segments for anastomosis in avulsion injuries: experimental studies.

The role of side branches, when the parent arterial trunk is stretched, with emphasis on preventing the effects of avulsion injury, was investigated in an experimental model. In ten New Zealand rabbits, the femoral arteries were isolated with and without side branches in the left and right legs, respectively, and controlled longitudinal traction was applied. The elongation of the arteries just before avulsion rupture at each side, with and without side branches, was compared, by measuring the initial and final length from the inguinal ligament to the mid-point of the distance between the inguinal ligament and the saphenous bifurcation.

Lengthening of replanted or revascularized lower limbs: is length discrepancy a contraindication for limb salvage?

Some replantation cases require substantial bone shortening for primary closure. Leg-length discrepancy can be restored by lengthening of the replanted or revascularized extremities. Between 1991 and 2000, four patients with four total and two subtotal below-knee amputations had replantation or revascularization for their severely damaged extremities.

A modified method of microvascular autogenous interposition vein grafting for vascular reconstruction.

A modified technique of vein grafting for vascular reconstruction that facilitates surgical procedures by preventing size, diameter, and length discrepancies as well as twisting, is presented. The distal end of the harvested vein graft is ligated, and the graft is inflated with heparinzed saline. The determination of the small side branches makes ligation easier.
