Intraoperative fluid management in adult spinal deformity surgery: variation analysis and association with outcomes.

Purpose: To evaluate the variability in intraoperative fluid management during adult spinal deformity (ASD) surgery, and analyze the association with complications, intensive care unit (ICU) requirement, and length of hospital stay (LOS).

Methods: Multicenter comparative cohort study. Patients ≥ 18 years old and with ASD were included.

Accuracy of Phantomless Calibration of Routine Computed Tomography Scans for Opportunistic Osteoporosis Screening in the Spine Clinic.

Study Design: Diagnostic accuracy study.

Objective: To establish a simple method of phantomless bone mineral density (BMD) measurement by using preoperative lumbar Computed Tomography (CT) scans, and compare the accuracy of reference tissue combinations to diagnose low BMD against uncalibrated Hounsfield units (HUs).

Summary Of Background Data: HUs are used as a measure of BMD; however, associations between HU and T-scores vary widely.

Closed versus medial open reduction in the treatment of developmental dysplasia of the hip under age 1: A retrospective comparative study.

Objective: This study aimed to compare the mid-term results of closed reduction (CR) versus medial open reduction (MOR) in the treatment of children with developmental dysplasia of the hip (DDH) under age 1.

Methods: Thirty-four patients with DDH (41 hips) were included in this retrospective study with a mean follow-up of 4.2 years (range: 2-6.

Safety and efficacy of growth-friendly instrumentation for early-onset scoliosis in patients with spinal muscular atrophy type 1 in the disease-modifying treatment era.

Purpose: To evaluate the safety of growth-friendly instrumentation for early-onset scoliosis (EOS) in patients with spinal muscular atrophy (SMA) type 1 who received disease-modifying treatment (DMT) and analyze short-term efficacy.

Methods: Retrospective search was conducted between 2017 and 2023. Patients with genetically confirmed SMA type 1 who were surgically treated for spinal deformity and receiving DMTs (nusinersen, risdiplam, or onasemnogene abeparvovec) were included.

Management of low back pain accompanying sagittal plane pathologies in children: Spondylolysis/spondylolisthesis and Scheuermann's disease.

Background: Low back pain in childhood was underappreciated for a long time, but recent studies report higher prevalences, up to 70%. Two of the common causes are spondylolyis/spondylolisthesis and Scheuermann's disease. These disorders are relevant in a way they both cause significant back pain, and may disrupt the sagittal spinal balance.

Predictive value of different glycemic control markers in total hip or knee arthroplasty: A prospective study.

Objective: The optimal glycemic control marker before total hip or knee arthroplasty remains inconclusive. Hemoglobin A1c (HbA1c) is widely used, while fructosamine may be valuable for predicting periprosthetic joint infection (PJI). Fructosamine levels can be affected by serum albumin levels; albumin-corrected fructosamine (AlbF) can be calculated to overcome this issue.

Intraoperative medial wall disruption in Dega pelvic osteotomy: Does it effect the radiographic outcome at medium-term?

Objectives: To compare the radiographic outcomes of our patients who encountered medial wall disruption, with those who did not while undergoing Dega osteotomy.

Methods: We retrospectively reviewed the records of 95 hips with developmental dysplasia of the hip who were treated with Dega pelvic osteotomy. Hips were divided into 2 groups according to medial wall disruption: group A included the hips with medial wall disruption, while group B included the hips without disruption.

Osseous Ilio-Trochanteric Bars as an Etiology of Hip Contracture in a Child with Congenital Contractures: A Case Report.

Case: A 5-month-old female patient presented with bilateral lower-limb deformities. Hips were fixed at 100° abduction, 15° flexion and 45° external rotation, flexion contracture in the knees, and bilateral teratologic equinovarus deformities. Radiographs revealed ilio-trochanteric osseous bars as the etiology of hip contractures.

The Effect of Apical Vertebra Position on Growing Rod Treatment: A Clinical and Finite Element Study.

Background: Growing rods (GRs) is a commonly utilized technique for the management of early-onset scoliosis. The significance of the position of the apical vertebrae relative to the rods is not known. The purpose of this study is to analyze the potential effects of the position of the apical vertebrae in relation to the GRs on deformity control through plain radiographs and finite element analysis (FEA) modeling.

Evaluation of the Effects of Transforming Growth Factor-Beta 3 (TGF-β3) Loaded Nanoparticles on Healing in a Rat Achilles Tendon Injury Model.

Background: Achilles tendon (AT) midsubstance injuries may heal suboptimally, especially in athletes. Transforming growth factor-beta 3 (TGF-β3) shows promise because of its recently discovered tendinogenic effects. Using poly(lactic-co-glycolic acid)-b-poly(ethylene glycol) (PLGA-b-PEG) nanoparticles (NPs) may enhance the results by a sustained-release effect.

The efficacy of two-hole tension band plates in the treatment of lower extremity limb length discrepancy.

The main purpose of our study was to investigate the efficacy of dual two-hole tension band plates in the treatment of lower extremity limb length discrepancy (LLD). We retrospectively reviewed patients who underwent epiphysiodesis utilizing dual two-hole tension band plates due to lower extremity LLD between January 2012 and June 2018. The efficacy of epiphysiodesis was defined as the inhibited percentage of the expected growth of the physis between two time intervals and was calculated between 0-6 months and 6-18 months as the primary outcome.

Synovial Non-langerhans Cell Histiocytosis of the Shoulder: A Case Report and Review of the Literature.

Introduction: Histiocytoses are rare disorders and most orthopedic surgeons are unfamiliar with this diagnosis. We report a case of synovial non-Langerhans cell histiocytosis (LCH) located in the shoulder, which has not been reported in the literature previously.

Case Report: A 24-year-old female patient presented to our clinic with shoulder pain and decreased range of motion.

Biceps Tenodesis versus Tenotomy with Fast Rehabilitation Protocol-A Functional Perspective in Chronic Tendinopathy.

The study aimed to evaluate the results after arthroscopic tenodesis and tenotomy of the biceps tendon (LHBT), coupled in tenotomy modality with a personalized postoperative rehabilitation protocol. The study included patients who underwent arthroscopic biceps tenotomy or tenodesis due to chronic biceps tendinopathy. Postoperatively, a standard rehabilitation program was prescribed to the tenodesis group and personalized was introduced in the tenotomy group, respectively.

Scapular body fractures: Short-term results of surgical management with extended indications.

Introduction: Scapular body fractures represent less than 1% of all skeletal fractures. Operative criteria and risk factors for scapular fracture instability are well defined. Non-operative management of scapular body fractures show satisfactory results but with shortening and medialization of the scapular body.

Proximal Humerus Tumors: Higher-than-Expected Risk of Revision With Constrained Reverse Shoulder Arthroplasty.

Background: The treatment of proximal humerus tumors with endoprostheses is associated with a high risk of implant-related surgical complications. Because of extensive soft-tissue resection and muscular detachment during surgery, instability is the most common serious complication. A reverse total shoulder arthroplasty with a highly constrained design is one option to mitigate instability, but few studies have reported the results of this prosthesis for proximal humerus tumor resections.

Effectiveness of abduction orthosis for the treatment of acetabular dysplasia.

Objectives: This study aims to evaluate the effectiveness of full-time bracing in residual acetabular dysplasia (RAD) and the effect of previous Pavlik harness usage on the results of treatment with abduction orthosis.

Patients And Methods: We retrospectively reviewed 80 patients (9 males, 71 females; mean age 6±0.8 months; range, 5 to 7 months) with developmental dysplasia of the hip (119 dysplastic hips) treated with hip abduction orthosis.
