Risk factors for pancreatitis after posterior spinal fusion in children with cerebral palsy.

This study reports on the prevalence and risk factors of acute pancreatitis after posterior spinal fusion for cerebral palsy scoliosis. 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.

The efficacy of subcutaneous local analgesic infusion in the early postoperative period after bilateral total knee arthroplasty.

Objectives: This study aims to evaluate the analgesic and functional efficacy of subcutaneous local analgesic infusion (ScLAI) in the early postoperative period (especially on the second postoperative day) in patients undergoing simultaneous bilateral total knee arthroplasty with an intraoperative periarticular injection (PAI) of local analgesic cocktail.

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).

Long-term Outcome of External Tibial Derotation Osteotomies in Children With Cerebral Palsy.

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.

Long-term Outcome of Internal Tibial Derotation Osteotomies in Children With Cerebral Palsy.

Background: External tibial torsion (ETT) is a common bony 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.

Gait Pattern and Lower Extremity Alignment in Children With Diastrophic Dysplasia.

Background: The aim of this study was to describe the dynamic lower extremity alignment in children with diastrophic dysplasia (DD) by 3-dimensional gait analyses. 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.

Diagnostic efficacy of standard knee magnetic resonance imaging and radiography in evaluating integrity of anterior cruciate ligament before unicompartmental knee arthroplasty.

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.

Hip Reconstruction in Children With Unilateral Cerebral Palsy and Hip Dysplasia.

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.

Biomechanical evaluation of syndesmotic screw design via finite element analysis and Taguchi's method.

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.

Suture anchor fixation strength with or without augmentation in osteopenic and severely osteoporotic bones in rotator cuff repair: a biomechanical study on polyurethane foam model.

Background: The purpose of the present study was to compare the results of various types of anchor applications with or without augmentation in both osteopenic and severely osteoporotic bone models.

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.

An assessment of sleep quality in patients undergoing total knee arthroplasty before and after surgery.

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.

Femoral neck stress fracture in children: a case report, up-to-date review, and diagnostic algorithm.

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.

Biomechanical evaluation of syndesmotic screw position: a finite-element analysis.

Objectives: To evaluate the stresses in syndesmotic screws and widening of syndesmosis under loading after placement of the screws at different levels from the ankle joint line and to determine the optimal level.

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.

Three-dimensional finite element analysis used to compare six different methods of syndesmosis fixation with 3.5- or 4.5-mm titanium screws: a biomechanical study.

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.

Anatomical evaluation and stress distribution of intact canine femur.

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.

Pin site care during circular external fixation using two different protocols.

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.
