Relationship of Patellofemoral Angles and Tibiofemoral Rotational Angles With Jumper's Knee in Professional Dancers: An MRI Analysis.

Background: Jumper's knee is a type of tendinopathy affecting the distal insertion of the quadriceps tendon (25% of cases) or the patellar tendon. It has been shown that frontal-plane measurements, such as genu valgum, genu varum, an increased quadriceps angle, a protuberant tibial tuberosity, patella alta, and short hamstring muscles, may be related to jumper's knee.

Purpose: To investigate the effects of tibiofemoral rotational angles and patellofemoral (PF) angles on the development of jumper's knee in professional folk dancers.

Patellofemoral Chondropathy Areas in Folk Dancers: An MRI Study.

Background: Patellofemoral chondropathy (PFC) is one of the most important causes of patellofemoral pain syndrome. PFC may occur as a result of anatomic reasons such as patellar malalignment and/or increased patellofemoral joint stresses. Most research on this subject has involved sports injuries and anatomic variations.

Evaluation of oxysterol levels of patients with silicosis by LC-MS/MS method.

Silicosis is one of the prolonged and irreversible occupational diseases. Crystalline silica dust, which has been linked with silicosis, occurs in different industrial areas such as constructions, ceramic, quarry, and pottery. There are significant numbers of newly diagnosed cases every year in Turkey.

Traumatic knee injury patterns in Anatolian folk dancers: a case series and literature review.

Lower extremities, especially the knee region, are susceptible to traumatic injuries because of long-lasting hard landings and impacts. Most of the injuries described in the literature are associated with ballet. In this review study, the authors tried to present the traumatic knee injury patterns of the Anatolian folk dance.

Relationship of Popliteus Sulcus Depth and Tibiofemoral Rotational Alignment with Popliteus Tendinitis in Professional Folk Dancers Exposed to Turnout Positions: An MRI Analysis.

Aims: The popliteus musculotendinous unit plays the major role in range of motion, rotation and stabilization of the knee. Frequent repetition of the rotational strains such as turnout in dancers may be the cause of popliteus tendinitis. In addition, popliteus sulcus depth (PSD) and PSD/lateral condyle width (LCW) ratio are also highly related with popliteal tendinitis in professional folk dancers.

Overuse Injuries in Professional Anatolian Folk Dancers: A Descriptive Study Verified with MRI.

Background: Professional dancers are artists as well as athletes who push their bodies beyond limits for aesthetic expression. Therefore, overuse injuries are common. We present our findings on overuse injuries in Anatolian (Turkish) folk dancers.

Minimally invasive plate osteosynthesis (MIPO) in diaphyseal humerus and proximal humerus fractures.

Objective: Our aim was to evaluate the results of minimally invasive plate osteosynthesis (MIPO) using locking plates in diaphyseal humerus and proximal humerus fractures.

Methods: Nine patients who underwent open reduction and MIPO for the treatment of diaphyseal and proximal humerus fractures between June 2006 and October 2009 were included in this study. One S3(®) and 8 PHILOS(®) plates were used.

Fractures of the fingers missed or misdiagnosed on poorly positioned or poorly taken radiographs: a retrospective study.

Background: Missed fractures, the most common diagnostic error in emergency departments, are usually the result of a misread radiograph or the failure to obtain a radiograph. However, a poorly positioned or poorly taken radiograph may also result in diagnostic errors. We sought to analyze the frequency of missed or misdiagnosed finger fractures that could be attributed to inadequate radiographs.

Simultaneous repair of chronic full-thickness rotator cuff tears during fixation of proximal humerus fractures and clinical results.

Objectives: We investigated the incidence of chronic rotator cuff tears encountered during fixation of proximal humerus fractures with locking plate-screw systems, and evaluated the functional results of simultaneous surgical repair of these injuries.

Methods: A total of 111 patients underwent surgical treatment for proximal humerus fractures. Of these, nine patients (8 females, 1 male; mean age 73 years; range 56 to 84 years) who had concomitant chronic full-thickness rotator cuff tears were included in the study.

Complications encountered in proximal humerus fractures treated with locking plate fixation.

Objectives: We evaluated the complications encountered following locking plate fixation of proximal humerus fractures.

Methods: The study included 103 patients (70 females, 33 males; mean age 62 years; range 21 to 90 years) who were treated with open reduction and locking plate fixation for proximal humerus fractures between September 2005 and April 2009. Fixation was performed using the PHILOS locking plate in 93 patients, and S3 humerus plate in 10 patients.

Delayed rupture of the extensor hallucis longus and extensor digitorum communis tendons after breaching the anterior capsule with a radiofrequency probe during ankle arthroscopy: a case report.

A 40-year-old man with early arthritis, loose bodies, and anterolateral joint impingement symptoms in his left ankle, which was refractory to noninvasive therapeutic modalities for 1 year, underwent ankle arthroscopy and radiofrequency thermal ablation. The anterior capsule of the ankle joint was breached by the radiofrequency probe while the loose bodies were removed from the anterior recess, exposing the extensor tendons and resulting in a delayed spontaneous rupture of the extensor hallucis longus tendon and extensor tendons to the second and third toes. The extensor hallucis longus tendon was repaired with a semitendinosus tendon graft, and extensor digitorum tendons underwent primary repair.

The pedicle screw fixation with vertebroplasty augmentation in the surgical treatment of the severe osteoporotic spines.

Study Design: Retrospective clinical study.

Objective: To present the early clinical results of pedicle screw fixation augmented by vertebroplasty using polymethylmethacrylate in severely osteoporotic patients requiring spine surgery due to the neurologic deficit.

Summary Of Background Data: It is postulated that combining a formal vertebroplasty-that is, maximum filling of the trabecular space with polymethylmethacrylate-with pedicle screw placement in osteoporotic vertebrae could result in resistance to pullout forces significantly.

[Surgical treatment of elbow dislocations accompanied by coronoid fractures].

Objectives: We evaluated the results of surgical treatment for elbow dislocations accompanied by Regan-Morrey type 2-3 coronoid fractures.

Methods: Eight patients (6 males, 2 females; mean age 44 years; range 23 to 76 years) underwent surgical treatment for elbow dislocations accompanied by a coronoid fracture. Three patients had Regan-Morrey type 2, five patients had type 3 coronoid fractures.

Radiographic and pathological stages of the changes at the bone-cement interface: an in-vivo experimental study.

Introduction: Chemical and physical effects of cementation cause radiographic and histological changes at bone-cement interface. These changes can be of interest in the assessment of the residual lesions and subsequent recurrences after local resection and cementation of local aggressive tumours.

Aim: The aim of the study was to evaluate the evolution and determine the stages of the changes that occur at the bone-cement interface after cementation of cavitary lesions.

[The results of internal fixation of proximal humeral fractures with the PHILOS locking plate].

Objectives: Proximal and diaphyseal humeral fractures are common especially in the elderly, presenting as a challenging problem due to their high complication rates following surgical treatment. In this prospective study, we evaluated the results of patients treated with the PHILOS (Proximal Humeral Internal Locking System) locking plate, a new technique recently developed by the AO/ASIF.

Methods: Forty-one patients who were treated with the PHILOS plate for proximal humeral fractures were evaluated in two age groups.

Pseudomeningocele in communication with the facet joint: demonstration by computerized tomography-arthrography.

Pseudomeningocele is an uncommon but well-known complication of lumbar spine operations. Although it is mostly asymptomatic and managed conservatively in most cases, it is claimed as a causative factor of failed back surgery syndrome and requires surgery in some cases. Usually, its diagnosis is confidently done with imaging modalities such as magnetic resonance imaging, computed tomography and myelography.

Posterior only pedicle screw instrumentation with intraoperative halo-femoral traction in the surgical treatment of severe scoliosis (>100 degrees).

Study Design: Retrospective clinical study.

Objective: To report the results of surgical correction achieved by intraoperative halo-femoral traction and posterior only pedicle screw instrumentation in severe scoliosis (scoliosis greater than 100 degrees ).

Summary Of Background Data: Although previous reports show the effectiveness of preoperative halo traction in the treatment of severe spinal deformity, the intraoperative use of halo-femoral traction in conjunction with posterior pedicle screw instrumentation has never been reported in patients with severe spinal deformity.

[Hot saline irrigation as an alternative local adjuvant therapy in local aggressive bone tumors].

Objectives: This study aimed to develop an alternative thermoinactivation method for biological inactivation of microscopic contamination on the cavity wall following curettage of local aggressive tumors. Hot saline irrigation was applied at various temperatures to bone cavity, with or without tourniquet on the extremity and temperature changes and local effects were investigated in vivo.

Methods: Bone cavities 12 cm3 in size were created in the condylar regions of the hind legs in nine female adult sheep.

[Comparison of temperature increments in bone cavities induced by methylmethacrylate and heated saline solution].

Objectives: We administered saline solution at 70 degrees C and methylmethacrylate to varying volumes of bone cavities and compared temperature changes produced in bone regions at varying distances to the cavity wall.

Methods: We created varying sizes of cavities in the femoral heads of 20 human cadavers (6, 10, 12, and 20 cubic centimeters) and in the knee region of a human cadaver (6, 10, 12, 20, 30, and 40 cubic centimeters). Initially, saline solution at 70 degrees C was administered to all the cavities for 15 minutes by a pulse-irrigation method, during which temperature changes induced within the bone cavity and at specific distances (1, 2, 3, and 10 mm) to the cavity wall were recorded.
