Relationship of Plasminogen Activator Inhibitor 1 4G/5G Gene Polymorphism and Nontraumatic Lunatum Avascular Necrosis.

Purpose: Plasminogen activator inhibitor 1 (PAI-1) is a critical enzyme that regulates coagulation and fibrinolytic systems. The aim of this study was to determine the role of PAI-1 4G/5G polymorphism in nontraumatic avascular necrosis of the lunate.

Methods: The study included 45 patients with Kienböck disease and 45 healthy individuals as a control group.

Femoral bowing plane adaptation to femoral anteversion.

Background: Femoral bowing plane (FBP) is the unattended subject in the literature. More over the femoral shaft with its bowing is neglected in established anteversion determination methods. There is limited information about the relationship between FBP and anteversion.

Relationship of side dominance and ultrasonographic measurements of pronator quadratus muscle along with handgrip and pinch strength.

Aims: We ascertained effects of hand dominance in both right and left-handed volunteers on the thickness and cross sectional area (CSA) of pronator quadratus (PQ) muscle as measured by the axial and sagittal views of ultrasound imaging. Secondly, we also aimed to document the extent of the relationship between the PQ measurements and handgrip.

Materials And Methods: Healthy adults from the volunteer medical staff were included in the study.

Humeral shaft fractures and radial nerve palsy: early exploration findings.

Objectives: This study aims to present the results of early nerve explorations in cases with radial nerve palsy associated with humeral shaft fracture and to investigate in which cases early nerve explorations may be beneficial.

Patients And Methods: Twenty-four patients (17 males, 7 females; mean age 36 years; range 18 to 72 years) with complete sensory and motor radial nerve damage associated with humeral shaft fracture were retrospectively analyzed. The patients with high-energy trauma and the ones who had spiral and segmental fractures with low energy traumas were included in the study.

Collagen membrane wrapping around methotrexate-containing calcium-phosphate cement reduces the side effects on soft tissue healing.

Objectives: This study aims to evaluate whether the collagen membrane (membrane) wrapping around the methotrexate (MTX)-containing calcium-phosphate cement (CPC) reduces the side effects on soft tissue healing.

Material And Methods: In 36 rats, femoral bone defects were created and treated in six groups which were CPC only, CPC and membrane wrapping around, CPC containing 2% MTX, CPC containing 2% MTX and membrane wrapping around, CPC containing 5% MTX, CPC containing 5% MTX and membrane wrapping around.

Results: Histological examinations revealed a statistically significantly improved healing in the connective tissue samples of the CPC containing 5% MTX group wrapped around by membrane compared to those without membrane (p=0.

[Functional outcomes and quality of life in patients with proximal row carpectomy].

Objectives: This study aims to assess pain, functional status, patient satisfaction, and quality of life in patients with proximal row carpectomy.

Patients And Methods: Between December 2007 and November 2011, demographic, clinical, and operational data, and physical therapy program of 16 patients (11 males, 5 females; mean age 41.4±16.

Ultrasonographic measurement of the distal femoral cartilage thickness in patients with unilateral transtibial amputation.

Background: Lower limb amputation sometimes predisposes to degenerative secondary disorders.

Objectives: To evaluate the distal femoral cartilage thicknesses of patients with unilateral transtibial amputations using ultrasound and to investigate the relationship between cartilage thickness and disease-related parameters.

Study Design: Cross-sectional study.

Distribution of the metatarsophalangeal sesamoids in Turkish subjects.

No statistically significant pattern of metatarsophalangeal sesamoid distribution has been reported in the literature in relation to genetic pool or group, unilaterality or bilaterality, or sesamoid division. A study was undertaken to evaluate the presence and distribution of the metatarsophalangeal sesamoid bones of the foot in Turkish subjects. A total of 602 foot radiographs from 371 patients without forefoot complaints other than those of the hallux were included in the study.

Comparison of injection modalities in the treatment of plantar heel pain: a randomized controlled trial.

In a prospective randomized study of plantar heel pain, 44 patients were treated with injection of 1 mL of 2% prilocaine using the peppering technique, 1 mL of 2% prilocaine combined with 2 mL of autologous blood, or 1 mL of 2% prilocaine mixed with 40 mg of methylprednisolone acetate. At 6-month follow-up, clinical improvement was evaluated by using a 10-cm visual analog scale and the rearfoot score of the American Orthopaedic Foot and Ankle Society. Results were analyzed using sample t-tests within groups and repeated-measures analyses of variance between groups.

The relation of joint laxity and trunk rotation.

A study was designed to evaluate the joint laxity during scoliosis screening, and to show if there is a relation of joint laxity values to the trunk rotation. One thousand, two hundred and seventy-three children (598 females, 675 males) with an average age of 10.4 years were screened with a scoliometer and forward bending for trunk rotations.

The acetabular teardrop and ultrasonography of the hip.

The acetabular teardrop is an important tool for the diagnosis of acetabular dysplasia. Since it was first described by Köhler its widespread use has not become established due to the relative subjectivity in classification of the types. The acetabular teardrop angle (ATA) is proposed for this purpose, and to show the teardrop's direct relation to acetabular development by correlating it with hip ultrasonography results.

A new technique for creating an abdominal window in a hip spica cast.

Opening an abdominal window in a hip spica type of cast can be a troubling maneuver for both orthopaedic surgeon and patient. We present a simple device to create an abdominal window more easily.

[Stress fracture of the fifth metatarsophalangeal sesamoid bone: a case report].

There is a paucity of published literature on the injuries of the lesser toe sesamoids of the foot. A fifty-six-year-old male patient without a major trauma history was diagnosed as having a stress fracture of the fifth metatarsophalangeal joint medial sesamoid bone. Conservative treatment was employed and the patient was followed-up for 25 months without any complaints.

Biomechanical evaluation of flexor tendon function after hamate hook excision.

Purpose: Hamate hook fractures are uncommon injuries for which treatment is controversial. Excision of the hamate hook is considered to be the preferred method of treatment but the effects of hamate excision are not clearly delineated. The purpose of this study was to determine what effect, if any, excision of the hamate has on flexor tendon function.

The use of amniotic membrane in flexor tendon repair: an experimental model.

Background: The objective of this study was to investigate the use of amniotic membrane as a long-term bioprosthesis in hand surgery. The role of the amniotic membrane was investigated in chickens with regard to the prevention of adhesion formation following tendon repair in zone II.

Methods: In the control group, the flexor tendon sheath was excised and the tendon repaired.

Hamstring shortening in healthy adults.

Hamstring shortening (HS) causes changes in the posture and walking ability in spastic children, however, there are no studies defining the abnormalities in patellar alignment in individuals with HS.Twenty-five patients with a primary complaint of anterior knee pain, having HS detected at physical examination, and 11 healthy individuals without any HS or knee discomfort as a control group are included in this study. Serial x-rays of the spine, pelvis and knee are taken and knee x-rays are evaluated for the position of the patella in both groups.
