Unlabelled: This study aimed to evaluate the outcomes of nonarthrodesis surgical treatment of hallux valgus (HV) deformity in children with cerebral palsy using radiographic and gait analysis parameters. There were 25 patients who had hallux valgus correction in 39 feet. The mean age at surgery was 15±2.

Pancreatitis diagnosis was based on elevated amylase or lipase above three times the upper normal limit. Perioperative data were compared between patients with and without pancreatitis.

Patients And Methods: Fifteen patients (1 male, 14 females; mean age 62 years; range 52 to 76 years) who underwent simultaneous bilateral total knee arthroplasty (30 knees) and who received the same pre- and intraoperative analgesic protocols were included in this randomized, double-blind, placebo-controlled study. By using a flexible catheter, bupivacaine was administered for ScLAI to either knee (ScLAI group) and placebo infusion was applied to the other one (control group).
Background: Internal tibial torsion (ITT) is a common boney deformity in children with cerebral palsy (CP). The current recommended treatment is tibial derotation osteotomy (TDO) to improve gait biomechanics. Satisfactory short-term results after TDO have been reported but long-term results have not been studied.

Our main hypothesis was that gait kinematics and kinetics are different than the age-normalized population and patellar dislocation can alter the gait in patients with DD.
Methods: A retrospective review of clinical data and radiographs was conducted for patients with DD who had gait analysis before lower extremity skeletal surgery excluding foot procedures.
Objective: The purpose of this study was to investigate the diagnostic efficacy of standard magnetic resonance imaging (MRI) and plain radiographs in determining the status of anterior cruciate ligament (ACL) for surgical decision-making processes in cases of medial unicompartmental knee arthroplasty (UKA).
Methods: A total of 59 knees of 36 consecutive patients who underwent knee replacement surgery were analyzed retrospectively. MRI scans were assessed independently by 3 observers (radiologists), while the plain radiographs were evaluated by an independent radiologist.
Background: Highly functioning children with unilateral cerebral palsy (CP) who have hip involvement (type IV hemiplegia) may present with hip dysplasia during their adolescence. The aim of this report is to assess the outcomes of combined femoral and acetabular reconstruction in this population.
Methods: This study is a retrospective review of all patients with unilateral CP, Gross Motor Function Classification System types I and II, who had hip reconstruction for unilateral dysplasia between 1989 and 2013.
Background: Screw fixation of syndesmotic injuries facilitates ligament healing and restoration of ankle stability, but failure of the screw might threaten the success of the treatment. Screw design parameters, such as outer diameter, inner diameter, thread pitch, leading edge radius, trailing edge radius, leading edge angle, and trailing edge angle, might have effects on the stresses that occur in the screws. This is the first study, to our knowledge, to investigate which geometric screw parameters play key roles in stresses that occur in screws used for syndesmotic fixation.

Methods: Two different types of suture anchors were tested in severely osteoporotic (SOP) and osteopenic polyurethane (PU) foam blocks using an established protocol. An Instron machine applied static loading parallel to the axis of insertion until failure, and the mean anchor failure strengths were calculated.
Objective: The aim of this study was to compare the sleep quality of patients who underwent total knee arthroplasty before and after the surgery and analyze the effect of total knee arthroplasty on sleep quality.
Methods: The study included 42 patients (32 females, 10 males) who underwent total knee arthroplasty for primary knee osteoarthritis. For each patient the preoperative 1 day and postoperative 3 months results of Pittsburgh Sleep Quality Index (PSQI) and 100-mm visual analogue scale (VAS) were compared.
Stress fracture of the femoral neck in skeletally immature individuals is a rare condition and generally seen as compressive type. Because the condition may lead to disastrous complications, femoral neck stress fracture must also be kept in mind in the differential diagnosis of pediatric hip pain. We present a case of compressive-type stress fracture of the femoral neck in a 10-year-old girl with left hip pain that was sustained for 4 weeks and emphasize the difficulty of early diagnosis with only a radiographic evaluation and put forward an algorithm for diagnosis and treatment.

Methods: From a set of computed tomographic data of an ankle, a 3-dimensional finite-element model was reconstructed. Six fixation configurations of the syndesmosis with placement of 3.
Background: Use of thicker and longer (four cortices) screws or of multiple screws seems to be more stable and efficient for syndesmosis fixation.
Methods: A three-dimensional finite element model of an ankle was constructed from serial axial sections from an existing two-dimensional computed tomographic image. Constructions of syndesmosis fixation with 3.
Background: In the biomedical field, three-dimensional (3D) modeling and analysis of bones and tissues has steadily gained in importance. The aim of this study was to produce more accurate 3D models of the canine femur derived from computed tomography (CT) data by using several modeling software programs and two different methods.
Method: The accuracy of the analysis depends on the modeling process and the right boundary conditions.
Objectives: Treatment of tibial fractures with Ilizarov external fixation is a valuable treatment alternative; however, development of problems at the pin site is one of the major drawbacks of this technique. Moreover, there is no general agreement regarding pin site care. The purpose of this study was to compare the efficacy of two different pin site care techniques after treatment of tibial fractures with an Ilizarov external fixator.
