The impact of pathogen sensitivity to antibiotics loaded in cement on the number of revisions and costs in the treatment of periprosthetic knee infection.

Objective: This study aims to evaluate the impact of the pathogen's sensitivity to the loaded antibiotics on infection resolution, the number of revisions, and the associated costs in patients undergoing revision total knee arthroplasty (rTKA) due to PJI.

Material And Methods: We reviewed the treatment and follow-up processes of 61 patients who underwent rTKA for late-stage PJI following primary total knee arthroplasty in our clinic. The study included 11 patients in the resistant group and 50 in the sensitive group in line with the power analysis results.

The relationship between the ratio of interpedicular distance increase and the ratio of spinal canal compromise in thoracolumbar burst fractures.

Background: The aim of the study was to investigate the relationship between the interpedicular distance increase ratio and the ratio of canal compromise in thoracolumbar burst fractures.

Methods: Thirty-one patients (18 male and 13 female) with an average age of 30.8 (14-57) who had been treated for thoraco-lumbar burst fractures in the Department of Orthopaedics and Traumatology were included in the study.

Intramedullary nail with integrated cephalocervical screws in the intertrochanteric fractures treatment: Position of screws in fracture stability.

Background: Stable fracture fixation is important in the treatment of intertrochanteric femur (ITF) fractures in the elderly population to prevent the loss of reduction, achieve early mobility, and restore independence. The aim of this study was to present the results of surgical treatment of stable and unstable ITF fractures using a trochanteric antegrade intramedullary nail with two cephalocervical screws in an integrated mechanism (Intertan®; Smith & Nephew, Memphis, TN) and evaluate the relationship between the loss of reduction and screw position in the femoral neck in two planes.

Methods: The authors investigated all varus misalignments and losses of reduction in 57 patients (22 males, 35 females) treated for ITF fractures with the Intertan® between 2010 and 2011.

Peritendinous injection of platelet-rich plasma to treat tendinopathy: A retrospective review.

Objective: The aim of this study was to determine factors associated with the likelihood of a better clinical outcome after the peritendinous injection of PRP for the treatment of chronic tendinopathy and identify whether PRP represents an effective treatment option for chronic tendinopathies.

Methods: The study included 214 patients (86 males and 128 females; mean age: 39.3 (18-75) years) who received PRP injections for tendinopathy refractory to conventional treatments.

Endoscopic calcaneoplasty: 5-year results.

Objective: The aim of this study was to evaluate the results of the endoscopic calcaneoplasty technique for the treatment of retrocalcaneal bursitis and Haglund's disease.

Methods: This study included 30 feet of 28 patients who underwent endoscopic surgery for Haglund's disease between 2003 and 2011. The inflamed bursa and posterosuperior surface of the calcaneus were removed with a shaver and bone resection performed until there was no friction on the Achilles tendon with the ankle in dorsiflexion.

Rotational malalignment after closed intramedullary nailing of femoral shaft fractures and its influence on daily life.

Background: Any intraoperative rotational malalignment during intramedullary nailing (IMN) of femoral shaft fractures will become permanent. We hypothesized that rotational malalignment of the femur and its compensatory biomechanics may induce problems in the hip, knee, patellofemoral and ankle joints. We purposed to clarify the influence of a femoral rotational malalignment of ≥10° on daily activities.

Shear wave elastography properties of vastus lateralis and vastus medialis obliquus muscles in normal subjects and female patients with patellofemoral pain syndrome.

Objective: The aim of our study was to define and compare the mechanical properties of the vastus lateralis (VL) and vastus medialis obliquus muscles (VMO) by the way of quantitative shear-wave elastography in male and female healthy control (HC) subjects, and in female patients with patellofemoral pain syndrome (PFPS).

Materials And Methods: Twenty-two healthy volunteers (11 male and 11 female) and 11 female patients with anterior knee pain were included in the study. The SWE examinations for VL and VMO were performed while the subjects were performing open kinetic chain exercises in neutral and 30° hip abduction.

Open reduction technique for overlapping and locked pubic symphysis.

A locked pubic symphysis can occur following a lateral compression injury of the pelvic ring when one pubic bone becomes entrapped behind the contralateral pubis or obturator foramen. In selecting the treatment modality, it is important to know the mechanism of injury. We presented the use of an open reduction technique in the treatment of a locked pubic symphysis in which open reduction external fixation application failed in the emergency department.

Abnormal proximal musculotendinous junction of the peroneus brevis muscle as a cause of peroneus brevis tendon tears: a cadaveric study.

Abnormal musculotendinous distal extension of the peroneus brevis has been implicated as a possible cause of peroneus brevis tendon tears. We investigated this relationship in 58 (46 male) fresh human cadavers. Torn lesions were classified according to Sobel et al.

Evaluation of the functional effects of anterior cruciate ligament bundles: a cadaveric experiment.

The influence of isolated deficiency of the anteromedial or posterolateral bundles of the anterior cruciate ligament (ACL) on knee kinematics has not been fully investigated. Thirty-two cadaveric knees were studied. The fibers of the anteromedial and posterolateral bundles were resected arthroscopically in alternating order in right and left knees.

[A case of brown tumor mimicking fibrous dysplasia in a patient with chronic renal failure].

Renal osteodystrophy is one of the major causes of morbidity in patients receiving long-term dialysis treatment for renal failure and after transplantation. Its clinical implications include high-turnover bone disease, low-turnover bone disease, osteomalacia, osteosclerosis, and osteoporosis. A 13-year-old boy who had been on dialysis treatment for renal failure was admitted with a pathologic supracondylar femur fracture after a minor trauma.

[Osteonecrosis of the knee].

Osteonecrosis of the knee was first described by Ahlback in 1968. Today, it is classified as spontaneous and secondary osteonecrosis. Spontaneous osteonecrosis is typically seen with unilateral involvement in patients older than 60 years.

[Brachial plexus neuropathy (stinger syndrome) occurring in a patient with shoulder laxity].

The stinger syndrome is a common neuropathy caused by traction or compression of the brachial plexus. In general, it is seen in young adults involved in sport activities and a major contact trauma is the rule. An 11-year-old boy with bilateral glenohumeral joint laxity had pain in the left shoulder, numbness and decreased strength in the left arm that developed after striking against a wall while running, with the left shoulder in extension and the neck in minimal lateral flexion to the contralateral side.

Anatomic relationship between elbow arthroscopy portals and neurovascular structures in different elbow and forearm positions.

Twenty fresh cadaveric elbows were used to evaluate the proximity of neurovascular structures to the six arthroscopic portals of the elbow at different positions. After distention of the joint, 4-mm Steinmann pins were introduced into the elbow from the portal's entry points. After surgical dissection, the proximity of the neurovascular structures to the pins was measured in 5 different positions.

[Open surgical treatment of posterior instability of the shoulder].

Posterior instability of the shoulder remains a diagnostic and therapeutic challenge, with a growing incidence especially in athletes. Evaluation of the type of the instability, whether unidirectional or multidirectional, is very important with regard to treatment. Although many patients benefit from strengthening and balancing rotator cuff muscles and scapular stabilizers, surgical procedures may be required in those unresponsive to conservative treatment.
