A novel reduction support frame for management of unstable tibial fractures with intramedullary nail: Preliminary report.

Background: Management of unstable tibial fractures (UTF) can be challenging due to widening of the proximal and distal metaphyseal zone, soft tissue problems, and poor vascularity. We aimed to compare the effect of novel tibial orthopedic reduction support (TORS) frame constructed by re-used tubular external fixator systems and manual traction with regard to the quality of re-duction, and fracture healing.

Methods: A total of 65 patients who were admitted with UTF and underwent intramedullary nailing were assessed; 43 patients un-derwent manual traction technique, and 22 patients underwent TORS technique.

The effect of the platelet-rich plasma on osteogenic potential of the periosteum in an animal bone defect model.

Objectives: This study aims to investigate whether plasma-rich plasma (PRP) enhances the osteogenic potential of periosteal grafts used to repair bone defects and maintains both histologically and biomechanically more durable bone tissue.

Materials And Methods: A standard bone defect was formed to the left femurs of 54 Sprague-Dawley rats and three groups were formed. In the first group (n=18), no periosteal repair was done for bone defect.

Rafting technique without bone grafting in reverse Hill-Sachs lesions.

In this article, we report a case of bilateral posterior shoulder instability, having reverse Hill-Sachs lesions of 25 to 50% of the articular surface on the right side, and of 50% on the left side. The defects were anatomically reconstructed after tuberculum minus osteotomy by elevation of the articular surface and buttressing with raft screws without graft usage. Early rehabilitation with pendulum shoulder exercises was started at third postoperative day.

Comparison of two medial epicondylectomy techniques in cubital tunnel syndrome.

Objectives: This study aims to compare partial medial epicondylectomy (PMe) and distal medial epicondylectomy (DMe) techniques in terms of sensory and motor improvements, functional results and complications.

Congenital extensor tendon dislocation causing pseudotriggering of the little finger.

The main complaints in extensor tendon dislocations are pain, swelling, sense of discomfort, snapping and difficulty in writing and forceful flexion. However, congenital extensor tendon subluxations may present with triggering of the fingers due to tendon dislocations. Unnecessary A1 pulley release may be performed for pseudotriggerring with unsuccessful results.

Postarthroscopy osteonecrosis of the knee.

Purpose: Spontaneous subchondral osteonecrosis of the knee joint confined to a localized area of one condyle can occur after arthroscopic procedures. Meniscal tears, arthroscopic meniscectomy, and radiofrequency chondroplasty are aetiological factors in the development of osteonecrosis. The aim of this study was to investigate whether the incidence of osteonecrosis increased when mechanical or radiofrequency chondroplasty was used in conjunction with arthroscopic meniscectomy.

Effect of partial, distal epicondylectomy on reduction of ulnar nerve strain: a cadaver study.

Purpose: To compare the decrease in ulnar nerve strains using a modification of medial epicondylectomy by removing the distal half of the medial epicondyle with in situ decompression and partial medial epicondylectomy.

Methods: Using 20 elbows of 10 fresh human cadavers, we measured the strain on the ulnar nerve using a microstrain gauge before and after in situ decompression. Then, we repeated the measurements after partial medial epicondylectomy on left elbows, and after distal medial epicondylectomy on right elbows.

Dorsal cutaneous innervation of the hand with respect to anatomical landmarks: is there a safe zone?

Objectives: In this study, we aimed to define the borders of the triangular area between the radial and dorsal nerves on the dorsum of the hand and to determine its dimensions using measurements between anatomic landmarks.

Materials And Methods: We statistically analyzed the relation between the distance from Lister's tubercle to the blending point of the central branches of radial and ulnar nerves and the distance between styloids on 14 hands of seven adult human cadavers (5 males, 2 females). The distances of nerve branches to vertical lines drown distally from both styloid processes were also compared with interstyloid distances to help in presuming the course of these nerves.

[The effectivity of magnetic resonance imaging findings in the diagnosis of bucket handle meniscal tears].

Objectives: This study aims to test the efficacy of magnetic resonance imaging (MRI) evaluation by a group who were blinded to the arthroscopic diagnosis in patients with known bucket handle meniscal tears.

Patients And Methods: In this study, MRI scans of 28 patients who were operated due to bucket handle meniscal tear with sufficient documentation were evaluated. Radiographic evaluation was performed by two different groups, including an orthopedist and radiologist.

Distal medial epicondylectomy. A modification of partial medial epicondylectomy for cubital tunnel syndrome: preliminary results.

Introduction: The medial epicondyle behaves as a fulcrum and a pulley that tethers the ulnar nerve during flexion. Excision of the distal half of the medial epicondyle sets the point of contact of the bone with the nerve proximally and decreases the traction effect of the medial epicondyle on the ulnar nerve. In this study, we aim to investigate the surgical and clinical results of excision of the distal half of the medial epicondyle in cubital tunnel syndrome (CuTS).

Clamp fixation to prevent unfolding of a suture knot decreases tensile strength of polypropylene sutures.

Purpose: Although sutures evolved in last decade and the product spectrum broadened largely, they can be still classified into two: monofilament and multifilament. Sutures are the mainstay of orthopedic procedures like fascial closures, tendon repairs or tenodesis. In every repair, a suture loop is created.

Comparison of two techniques in achieving planned correction angles in femoral subtrochanteric derotation osteotomy.

Increased femoral anteversion in cerebral palsy alters biomechanics of gait. Femoral subtrochanteric derotational osteotomies are increasingly performed to improve gait in cerebral palsy. The amount of angular correction can be determined and planned preoperatively but, accuracy in achieving planned angular correction has not been tested experimentally before.

[Bilateral traumatic patella fracture: a case report].

Patellar fractures are uncommon injuries and account for approximately 1% of all fractures. In this article, a 35-year-old male patient who sustained a collision deceleration accident with bilateral comminuted transverse patellar fractures is presented. For this patient, open reduction and internal fixation with tension band technique, using two Kirschner wires and cerclage wire was applied for both fractures.

[The efficacy and safety of limited incision technique in carpal tunnel release].

Objectives: This study aims to determine the safety and symptomatic and functional efficacy of median nerve decompression with 3 cm limited incision in carpal tunnel syndrome surgery.

Patients And Methods: Carpal tunnel release with a 3 cm limited palmar incision was performed on 91 hands in 83 patients. Patients were evaluated with Boston Carpal Tunnel Questionnaire, grip strength and pinch strength measurements, Semmes-Weinstein Monofilament test and two-point discrimination tests preoperatively, and at postoperative 3rd and 6th months.

Over-the-top knot placement technique enhances tensile stability of tendon repairs.

Background: Currently a major concern for the surgical treatment of Achilles tendon rupture repairs is the creation of stable enough fixation to allow early range of motion. It was documented that the weakest point in a suture loop is the knot. Thus, we hypothesized that moving the knot away from the repair junction (over-the-top Krackow technique) would increase the strength of the repair.

[The future of treatment for chondral and osteochondral lesions].

The population of patients with symptomatic focal or generalized cartilage lesions is growing due to prolongation of life expectancy and to increasing frequency of sports injuries. Cartilage tissue lesions which were defined as untreatable in the past have now become treatable thanks to advances in basic scientific research. With the development of technologies regarding biomaterial, cell and local regulators, and with the introduction of new surgical techniques, it is estimated that, in the near future, clinical applications of cartilage tissue engineering will also receive particular attention in our country.
