Arteriography and Histopathology of Vascular Beds in Traumatically Amputated Fingers.

Background: The success of replantation following traumatic amputation is determined by the quality of the vascular anastomoses. The purpose of this study was to assess the vascularity of injured arteries from traumatically amputated digits using arteriographic and histopathological analysis.

Methods: 25 amputated digits were included in the study.

Effect of oxytocin administration on nerve recovery in the rat sciatic nerve damage model.

Background: Growth factors such as nerve growth factor (NGF) and insulin-like growth factor-1 (IGF-1) have been shown to play a role in the healing process of nerve injury. Recent researches have also shown that oxytocin administration activates these growth factors of importance for the healing of nerve tissue. The objective of the present study was to evaluate the effects of oxytocin on peripheral nerve regeneration in rats.

Histomorphological comparison of immobilization and denervation atrophies.

Objective: The aim of this study was to compare the histomorphological changes in the muscle tissue after immobilization and denervation atrophies in an animal model.

Methods: The study included 30 Ross-800 hybrid chickens (60 legs) divided into two study (immobilization and denervation) and two control groups. The knee and ankle joints were fixed with a Kirschner wire in the immobilization atrophy group and sciatic nerve resection was performed in the denervation group.

A case of ingrown toenail accompanied by extreme soft tissue hypertrophy to the extent of invisible nail.

Ingrown nails occur when the nail fold grows inwards into the nail bed. This condition affects daily life and causes a loss of labor, and therefore, should be meticulously tackled and immediately treated. Ingrown nail is categorized in three stages based on pain, erythema, infection, drainage, and the presence of granulation tissue.

Treatment of reverse Hill-Sachs lesion by autograft reconstruction.

Reverse Hill-Sachs lesion is a defect caused by the anterior compression fracture of the humeral head in posterior shoulder dislocation. We present a 34-year-old male patient with pain and limited joint mobility in the right shoulder due to a fall following electric shock 2 days prior to admission. Radiography and CT of the shoulder revealed posterior dislocation of the shoulder with a reverse Hill-Sachs lesion.

[Assessment of the effects of surgical treatment options for cubital tunnel syndrome on the ulnar nerve by USG and EMG].

Objectives: The morphology and functional results of the ulnar nerve were evaluated in patients treated with simple decompression and anterior subcutaneous transposition due to the diagnosis of cubital tunnel syndrome.

Patients And Methods: Thirteen elbows of 13 patients (8 males, 5 females; mean age 41 years; range 25 to 56 years) treated with simple decompression and anterior subcutaneous transposition due to the diagnosis of cubital tunnel syndrome were investigated. The involvement was on the dominant side in six patients.

The effect of head trauma on fracture healing: biomechanical testing and finite element analysis.

Objectives: We aimed to evaluate the effect of head trauma on fracture healing with biomechanical testing, to compare the results obtained from a femur model created by finite element analysis with experimental data, and to develop a finite element model that can be employed in femoral fractures.

Methods: Twenty-two Wistar albino rats were randomized into two groups. The control group was subjected to femoral fracture followed by intramedullary fixation, whereas the head trauma group was subjected to femoral fracture followed by intramedullary fixation along with closed blunt head trauma.

Interposition arthroplasty in the treatment of hallux rigidus.

Objectives: We evaluated the outcomes of interposition arthroplasty performed for the treatment of hallux rigidus.

Methods: The study included 19 feet (4 left, 15 right) of 17 patients (14 females, 3 males; mean age 61+/-5 years; range 55 to 71 years) who were treated with interposition arthroplasty for hallux rigidus. According to the grading system of Coughlin and Shurnas, 18 feet were grade 3, one foot was grade 4.
