Positive effect of tadalafil, a phosphodiesterase-5 inhibitor, on fracture healing in rat femur.

Objectives: This study aims to investigate whether tadalafil accelerates fracture healing with an efficiency equal to that of sildenafil.

Materials And Methods: Fracture healing was studied using a rat closed femur fracture model. Forty-eight male Wistar albino rats (mean age 13 weeks; range 12 to 14 weeks) were divided into three groups: 16 received sildenafil (5 mg/kg/day per oral), 16 received tadalafil (1 mg/kg/day per oral), and 16 (control group) received saline daily.

Surgical management of bone metastases from urological malignancies: an analysis of 70 cases.

Objective: The purpose of this study was to evaluate symptomatic bone metastases from urological malignancies and the efficacy of surgical treatment of bone metastases in achieving local tumor control.

Methods: This was a retrospective observational study of patients diagnosed with bone metastases from urological malignancies who died from their diseases between 2002 and 2013. Data on clinicopathology, number and sites of bone metastasis, time to first and subsequent metastasis, survival after metastasis, nature of metastasis (blastic, mixed, lytic), type of surgical reconstruction, systemic affections, and visceral organ metastasis for 70 bone metastases from deceased urological malignancies patients (55 male, 15 female) with evidence of bone metastasis were statistically analyzed.

[Determination of the effect on the proximal femoral load distribution of diaphyseal cement support in femoral intertrochanteric fractures with calcar defect by finite element analysis].

Objectives: This study aims to investigate biomechanically positive and negative aspects of arthroplasties in combination with diaphyseal cement support as an alternative to calcar supported prosthesis on the proximal femoral load distribution, using finite element analysis method in a virtual environment in intertrochanteric fractures with calcar femoral defect.

Materials And Methods: Three femur models were created using the ANSYS method. These were named as a intertrochanteric fracture model without calcar defect, an intertrochanteric fracture model with thick cement mantle and calcar defect, and an intertrochanteric fracture model with thin cement mantle and calcar defect.

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.

Quadrilateral space syndrome caused by a humeral osteochondroma: a case report and review of literature.

Quadrilateral space syndrome (QSS) is a rare condition in which the posterior humeral circumflex artery and the axillary nerve are entrapped within the quadrilateral space. The main causes of the entrapment are abnormal fibrous bands and hypertrophy of the muscular boundaries. Many other space-occupying causes such as a glenoidal labral cyst or fracture hematoma have been reported in the literature.

Risk of superior gluteal nerve and gluteus medius muscle injury during femoral nail insertion.

Background: Abduction weakness and limping is a well-recognized complication of closed antegrade insertion of femoral nails. Iatrogenic injuries to the superior gluteal nerve and the gluteus medius muscle are the most likely contributing factors. The purpose of this study of cadavers was to assess the risk of nerve and muscle injury with various lower-limb positions used during nail insertion.

Children with fractures show higher levels of impulsive-hyperactive behavior.

Children with fractures have been reported to have impulsive-hyperactive behavior problems although whether they exhibited such behavior more often than children with other orthopaedic conditions is unknown. We investigated whether impulsivity-hyperactivity was more prominent in children with extremity fractures than in children with orthopaedic conditions not involving a fracture. From outpatient clinical intakes, we recruited 39 consecutive children with extremity fractures and 33 children with orthopaedic conditions not involving a fracture.

Open repair of Bankart lesions using suture anchors in hard workers.

The surgical techniques applied to recurrent anterior dislocation of the shoulder, especially in hard working patients, must reconstruct a stable shoulder joint with a good range of motion, which will not re-dislocate, so the patients can return to their hardworking duties. The aim of this study was to evaluate the results of open Bankart repairs with suture anchors, in high-demand sportsmen and hard workers with recurrent anterior shoulder dislocation. Thirty shoulders of 29 patients were included in the study.

Computerized tomography scout view for determining distal femoral resection angle in intramedullary instrumentation of total knee arthroplasty.

This study aims to investigate the results of distal femoral resection by determining the difference between mechanical and anatomical axes of femur using computerized tomography (CT) scout views in pre-operative planning of total knee arthroplasty. CT scout view of the lower extremities was taken before and after the operation in 16 patients undergoing total knee arthroplasty. Distal femoral resection was performed according to the previously determined ideal resection angle (IRA) using intramedullary instrumentation.

Localized pigmented villonodular synovitis of the knee: acute onset in pregnancy.

A pregnant patient in the first trimester presented with acute onset knee pain and effusion. As the clinical status was mimicking septic arthritis, surgery was performed. Arthroscopy demonstrated a local synovial tumor and excision was performed with arthrotomy.

Immunohistological analysis of normal and osteoarthritic human synovial tissue.

Intercellular communication mediated by cell surface antigens is important in the maintenance of synovial tissue (ST) integrity. Chronic inflammation is a common feature of osteoarthritis (OA). Cellular attachment to and migration into ST is one of the critical aspects of chronic inflammation.

Osteochondral multiple autograft transfer (OMAT) for the treatment of cartilage defects in the knee joint.

The ideal articular cartilage repair tissue should be durable and well-integrated. We have been performing osteochondral multiple autograft transfers (OMAT) since 1996 with the experience we had using carbon fiber implants. We call this technique OMAT instead of mosaicplasty because we use uniform osteochondral autografts.

Etiology of senile osteoporosis: a hypothesis.

Unlabelled: Osteoporosis is a major health problem characterized by compromised bone strength predisposing patients to an increased risk of fracture. It may cause morbidity and mortality in elderly men and women. The etiologic factors that lead to senile osteoporosis still are unclear.

Experience with the surgical treatment of radial polydactyly in adults.

Purpose: The aim of this study is to investigate the functional and cosmetic outcome after surgical reconstruction in adult patients.

Methods: Eleven hands of the 10 adult patients with radial polydactyly were treated surgically. Clinical and radiologic examination was performed and cases were classified according to the Wassel system.

Contrary intermittent skin release of complete syndactyly without skin graft in adults.

Introduction: There are many different surgical treatment techniques of complete syndactyly. Most of them are techniques involving using skin grafts. We developed a surgical technique that does not require skin grafts, which cause problems in the distal nail border pulp and interdigital web space.

Simultaneous bucket handle tear of both medial and lateral menisci of a knee with chronic anterior cruciate ligament deficiency.

Bucket handle meniscus tears constitute about 10% of all meniscal tears. Bucket handle tears of medial meniscus is three times more than lateral meniscus. Most of these tears are associated with anterior cruciate ligament (ACL) deficiency.

Ultrasonographic findings in pediatric fractures.

The aim of this study was to document and analyze ultrasonographic (US) findings in different types of pediatric fractures. Thirty-nine patients, aged between 1 and 14 years, with a fracture were included in the study. Patients were classified as complete or incomplete fractures.

Reliability of the safe area for the superior gluteal nerve.

The authors investigated the reliability of the safe area, which previously was defined to prevent injury to the superior gluteal nerve during the lateral approach to the hip, and its relation to body height. The distance between the point of entry of the superior gluteal nerve into the gluteus medius muscle and the greater trochanter, in the regions which were defined as the anterior and posterior halves of the muscle, were measured in 23 cadaveric hips. There was a significant correlation between the height of the cadavers and the distance in the anterior and posterior regions.

Histological alterations after irradiation of cartilage using Ho:YAG laser.

Objective: The authors carried out an experimental study to evaluate the histological alterations after irradiation of cartilage using Holmium:YAG (Ho:YAG) laser VersaPulse Select 60 watts and Infra Tome Delivery Systems 30 degrees Handpiece (spot size at fiber tip 0.4 mm; Coherent Medical, Palo Alto, CA).

Background Data: Recently, some authors reported cases with articular cartilage damage following arthroscopic laser surgery in the knee joint for the treatment of articular cartilage or meniscal pathology.

Chondroitin sulfate-coated polyhydroxyethyl methacrylate membrane prevents adhesion in full-thickness tendon tears of rabbits.

Polyhydroxyethyl methacrylate (pHEMA) membranes coated on one side with chondroitin sulfate (CS) were used to block adhesion physically and to reduce friction between healing flexor tendons and the surrounding tissue in rabbit forepaws after surgical repair. Digits with pHEMA-only, standard tendon sheath repair, and with no sheath repair were the controls. Over 12 weeks the CS-coated membranes were evaluated for joint flexion, adhesion limitation, and tendon healing progress.
