Surgical treatment of chondroblastoma using extended intralesional curettage with phenol as a local adjuvant.
CONCLUSION: The aggressive treatment of chondroblastoma by an extended intralesional curettage using high-speed burr with phenol as a local adjuvant seems effective in lowering the incidence of local recurrence and secondary more aggressive surgeries. Implantation of the bone defects that result from curettage with the synthetic bone substitutes is a good alternative due to rapid restoration of the mechanical strength with good remodeling.

Treatment of a sacral fracture associated with an intrasacral meningocele: A case report.
We report a case of sacral fracture complicated by an intrasacral meningocele in a 37-year-old male. The patient had a left sacral fracture with bilateral fractures of the superior and inferior pubic rami. The sacrum was fixed with a posterior plate and both superior pubic rami were fixed with an intramedullary screw. However, computed tomography myelogram and magnetic resonance imaging showed the intrasacral meningocele with the leakage of the cerebrospinal fluid into the buttocks and developed delayed union. Reoperation utilizing a strong anterior and posterior internal fixation combined with posterior bone grafting was ...

Finite element study of the effects of fragment shape and screw configuration on the mechanical behavior of tibial tubercle osteotomy.
CONCLUSION: The fragment shape with a step cut and fixation with two parallel horizontal or downward screws are suggested for TTO, while the trapezoidal screw configuration is not suggested. Furthermore, the downward screw configuration is a suitable strategy to reduce bone stress. PMID: 31311422 [PubMed - in process] (Source: Journal of Orthopaedic Surgery)

Posterior wall acetabular fracture fixation: A mechanical analysis of fixation methods.
Abstract Stable, anatomical fixation of acetabular fractures gives the best chance of successful outcome, while penetration of the acetabular articular surface with screws is associated with poor outcomes. Spring plates are an alternative to interfragmentary lag screws when penetration is a concern. A mechanical study comparing fracture stability and construct stiffness of three fixation methods for posterior wall acetabular fractures with transverse comminutions was performed. The three fixation methods tested were a posterior wall rim plate, a posterior wall buttress plate with separate lag screws and a posterio...

Three-dimensional analysis of acetabular cup orientation and an evaluation of the relationship with pelvic sagittal parameters.
This study aimed to evaluate the effect of total hip arthroplasty (THA) on sagittal pelvic parameters and to evaluate the effect of sagittal pelvic parameters on acetabular cup orientation. METHODS: The study included 86 patients who underwent THA for a diagnosis of unilateral coxarthrosis between 2011 and 2015. Measurements were taken of the preoperative and postoperative acetabular cup inclination (ACI), anteversion, and sagittal pelvic parameters. The effect of THA on sagittal pelvic parameters and the effects of the sagittal pelvic parameters on acetabular cup orientation were investigated. RESULTS: The sagit...

Pneumorachis from the cervical to the sacral spinal canal with spinal epidural abscess by gas gangrene.
We present a 70-year-old woman with severe diabetes mellitus, who experienced low back pain and left lower leg paralysis. Computed tomography showed air in the spinal canal from C4 to S5, and magnetic resonance imaging revealed an epidural abscess from Th11 to L1. Laboratory findings showed increases in inflammatory indicators and blood culture indicated the presence of Escherichia coli. The patient was treated conservatively with antibiotics. Neurological deficits and inflammatory data improved during the course. Follow-up imaging studies showed the disappearance of gas and epidural abscess. The existence of air in the sp...

Acute atraumatic bilateral acetabular insufficiency fractures.
Abstract Bilateral acetabular fractures have been documented in the setting of high-energy trauma, but few reports regarding atraumatic bilateral acetabular fractures exist. The following is a case report of bilateral insufficiency acetabular fractures which occurred acutely in the absence of trauma in a 49-year-old female. The case highlights the importance of perioperative awareness of those patients at significant risk of insufficiency fractures and offers a relatively elegant, less invasive solution for early mobilization in the context of acetabula insufficiency fractures.

Coronal shear fracture of distal humerus associated with olecranon fracture: A case report and pathomechanism.
Abstract Distal humeral coronal shear fractures are rare and account for around 1% of all fractures at the elbow level and 6% of the distal humeral fractures. Many studies have reported on the associated injuries involving the lateral collateral ligament injuries and radial head fractures in up to 40% and 30% of humeral fractures, but this combination of coronal shear fracture of the trochlea and capitellum associated with olecranon fracture is unusual. Here, we report two cases of distal humerus coronal shear fracture with olecranon fracture treated surgically and establish and discuss the pathomechanisms, diagno...

The calcar femorale: A new perspective.
Abstract It is the role of the hip joint to support the superincumbent body weight while its complex range of movement, under a variety of stresses, allows the individual to undertake a wide range of physical activities. It is then perhaps not surprising that a recent anatomical study shows that the upper femur has a structure commensurate with the complexity of its movements. Mechanically, the upper femur consists of two separate bones: the combined femoral head and neck and the femoral shaft. Both bones consist of a mixture of two different types: cancellous bone and cortical bone, each with its own characterist...

Different microbiological profiles between hip and knee prosthetic joint infections.
CONCLUSION: The prevalence of polymicrobial pathogens, anaerobes, and enteric GNB was higher in the prosthetic hip infection than in the prosthetic knee infection. The high prevalence of MRS, including Methicillin-resistant (MR) S. aureus and MR-CoNS in PJI, may warrant the need for empiric antibiotic therapy with broader coverage while pending the culture result of PJI. Although fungal and mycobacterial PJI cases are rare, the incidence of these infections is relatively high in Taiwan. Fungus and mycobacterium should also be taken into consideration whenever a persistent PJI case is encountered. PMID: 31117922 [PubMe...

Differences in outcome after cruciate retaining and posterior stabilized total knee arthroplasty.
CONCLUSIONS: PS knee replacements showed greater improvement in stiffness at 1 year postoperatively. There was no difference observed at 5 or 10 years postoperatively. PS knees had better functional outcomes at 1 year with a similar trend at 5 years postoperatively. LEVEL OF EVIDENCE: III.

Effective nutritional status screening in orthopaedic oncology patients and post-operative complications.
This study aims to determine the prevalence of malnutrition among orthopaedic oncology patients with malignant tumour during preoperative period. METHODS: This is a prospective observational study involving patients from the orthopaedic oncology unit who were undergoing surgery. They were assessed with Patient Generated Subjective Global Assessment (PG-SGA), Malnutrition Screening Tool (MST) and 3-minute Nutritional Screening (3MinNS) questionnaires. Anthropometric data such as body mass index, mid upper arm circumference (MUAC) and blood parameters such as serum albumin, total lymphocyte count and haemoglobin were al...
