Treatment options for patients with severe forms of proximal femoral focal deficiency include limb salvage procedures or foot ablation and use of a prosthesis. In patients with amputation, an ipsilateral knee arthrodesis can provide an efficient lever arm that is easy to contain in a prosthetic socket. We performed a retrospective review of proximal femoral focal deficiency patients treated at a single institution with knee arthrodesis. From 1986 to 2018, 26 patients (18 males, eight females) met study inclusion criteria (mean follow-up 13.2 years). Aitken C or D deformities were present in 65% of extremities. Ten patients...

Blount’s disease – an up-to-date insight with contemporary treatment guidelines deduced from critical analysis of a large 146 surgical case series
To elucidate an up-to-date insight and derive clear treatment guidelines for Blount’s disease deduced from critical analysis of 146 surgical case series. Cases were presented and analyzed separately under its two basic clinical groups and the author further derived four subcategories under each of these two groups; the first basic group was the early onset clinical variant; infantile tibia vara (ITV) included 56 cases. The second group was the late onset clinical variant; late onset tibia vara (LOTV) included 90 cases. Different operative procedures used for treatment of these cases were proximal tibial osteotomy (PTO), ...

Increase in dural ectasia size in scoliosis patients with Marfan syndrome
Increased dural ectasia and vertebral thinning in the lumbosacral spine are common in Marfan syndrome. Dural ectasia is unchanged in middle-aged patients, who have stopped growing. Therefore, evaluation from childhood to adulthood is mandatory. Sixteen patients [four men and 12 women; mean age:17.7 (8.6–33.5) years] with dural ectasia at final follow-up [mean follow-up: 10.4 (5.0–16.7) years] were enrolled. Dural sac diameter (DD)/vertebral diameter (VD) were measured on MRI or CT images of midline sagittal slices at the level of dural ectasia between L5 and S3. The widest part of the dural sac was evaluated with Fatto...

Direct vertebral rotation significantly decreases the pullout strength of the pedicle screw: a biomechanical study in adult cadavers
The pullout strength of the pedicle screws after direct vertebral rotation (DVR) maneuver is not known. This biomechanical study was performed to quantitatively analyze the pullout strength of a pedicle screw after DVR maneuver using human cadaveric vertebrae. Thoracic vertebral bodies from three cadavers were harvested and stripped of soft tissues. Thirty pedicles of 15 vertebrae were separated into two groups after bone mineral density measurements. Polyaxial 5.5 mm pedicle screws with appropriate length were inserted with a freehand technique for each pedicle. One Kirschner wire was inserted to the anterior part of ea...

Hypomagnesemia following posterior spinal fusion in adolescent idiopathic scoliosis
Adolescent idiopathic scoliosis (AIS) patients undergoing posterior spinal fusion (PSF) usually require surveillance in the pediatric ICU (PICU). Some reports have documented evidence of hypomagnesemia following PSF at PICU. Little has been studied about relationship between AIS and postoperative serum magnesium (Mg+2) levels. The aim of this study is to determine the prevalence and risk factors of hypomagnesemia in AIS patients admitted to PICU after PSF. IRB approved the cross-sectional study of AIS patients admitted to PICU after PSF from January 2016 to May 2017. Serum electrolyte levels of phosphorous, calcium, sodium...

Minimizing the need for high dependency unit support in adolescent idiopathic scoliosis surgery. Is enhanced recovery and the multidisciplinary team key?
Current trends in the surgical treatment of patients with adolescent idiopathic scoliosis (AIS) involve the use of high dependency unit (HDU) in the postoperative period. The British Scoliosis Society also recommends the availability of HDU support in the postoperative period for these patients. However, this practice may lead to unexpected theatre cancellations due to lack of availability of HDU bed on the day of surgery. We also hypothesize that this practice may eventually lead to longer inpatient stay for the patients. All AIS patients at our unit are managed on a paediatric ward postoperatively, without HDU support. T...

Clinical outcomes of selective fusion for the thoracolumbar-lumbar curve in patients with Lenke type 6C adolescent idiopathic scoliosis: a preliminary study
In this study, SLF for Lenke 6C AIS achieved a significant spontaneous correction of the unfused thoracic curve and yielded a comparable SRS-22 result at the final follow-up to that of Lenke 5C. Our findings suggest that SLF is a viable treatment option for Lenke 6C AIS. (Source: Journal of Pediatric Orthopaedics B)

Operative time in adolescent idiopathic scoliosis surgery: a need for a standard definition
Our objective is to report and define ‘operative time’ in adolescent idiopathic scoliosis (AIS) posterior spinal fusion surgeries. Documenting key times during surgery are important to compare operative risks, assess learning curves, and evaluate team efficiency in AIS surgery. ‘Operative time’ in literature has not been standardized. Systematic review was performed by two reviewers. Keywords included operative time, duration of surgery, and scoliosis. One thousand nine hundred six studies were identified, 1092 duplicates were removed and 670 abstracts were excluded. Of the 144 articles, 67 met inclusion and exclus...

Evaluation of the association between olecranon fracture and radial head subluxation or annular ligament displacement in children
Olecranon fractures are seen substantially more often in children than in adult and are potentially occult in nature. We noticed this fracture pattern in two cases of delayed Monteggia fracture. Our study purpose was to confirm whether olecranon fracture is associated with radial head subluxation or annular ligamentous displacement in children. In addition, we have developed an effective and simple approach to avoid serious treatment-related complications as much as possible. Forty-eight pediatric patients with olecranon fracture and normal radiocapitellar alignment on radiography were enrolled. All patients’ fingers, fo...

Association of radial head dislocation with fracture and acute plastic deformation of the ulna: unreported subtype of Monteggia fracture-dislocation in children
Treatment of a Monteggia fracture-dislocation primarily includes anatomical reduction and fixation of the ulna. However, in rare cases, reduction of the radial head remains impossible even after performing this standard procedure. We have encountered patients with Monteggia fracture-dislocation whose radial head could be reduced by ‘overcorrecting’ the ulna. In this retrospective study, we aimed to propose an unreported subtype of Monteggia fracture-dislocation. Data of three patients (age 6, 14, and 16 years) with Monteggia fracture-dislocations whose radial head could not be reduced by anatomical fixation of the ulna...

Prospective study of pediatric medial humeral epicondyle fractures nonoperatively treated. Clinical, radiologic, and functional evaluation at long term
The objective of the study is to evaluate the natural history of the medial epicondyle avulsion in children with nonoperative treatment (NOPT) on different magnitude of displacement and long-term follow-up. A prospective study of 34 patients with medial epicondyle avulsion with (NOPT) was performed. Clinical test (stability, strength, atrophy, tenderness, Tinel test, and range of motion), subjective scores [Visual Analog Scale (VAS), Likert scale, side-to-side valgus test], and objective four scores were performed. Age at the time of injury was 8.9 ± 2.81 years. Follow-up was 7 ± 2.81 years. Four of the patie...

Changing practice patterns: the impact of a cost analysis project on surgeons’ preference for treatment of pediatric displaced humeral lateral condyle fractures
A 2012 publication regarding the surgical management of pediatric lateral humeral condyle fractures (PLHCF) found that leaving pins exposed produced an average savings of $3442 per patient compared to burying pins, with fewer complications. The primary objective of this present study was to determine the impact of this cost analysis on surgeons’ treatment preferences at the same hospital. The secondary aim was to verify that leaving pins exposed continued to be a cost-effective and safe treatment strategy. We reviewed all PLHCF treated with open reduction and internal fixation at our institution between 2004 and 2017. Th...

Minimally displaced pediatric humerus lateral condyle fractures: risk factors for displacement and outcomes of delayed surgery
The purpose of this study was to identify risk factors for management failure in pediatric minimally displaced lateral condyle fractures of the distal humerus (LCHFx) and compare outcomes between initial nonoperative and operative cohorts. A retrospective chart review of LCHFx was conducted to identify children treated with displacement 1.2 mm to be the most predictive of nonoperative failure. Fractures with displacement of>1.2 mm had a 58.3% rate of failure compared to 1.3% for those (Source: Journal of Pediatric Orthopaedics B)

Treatment of type III supracondylar humerus fractures: adherence and limitations of American Academy of Orthopedic Surgeons Appropriate Use Criteria App
This study compares AAOS AUC recommendations with actual treatment performed in a cohort of patients treated for type III supracondylar humerus fractures. Medical record review of patients treated for type III supracondylar humerus fractures at our hospital from 2009 to 2016. Criteria required by the AAOS AUC were collected and entered into the AAOS AUC web-based application to determine the ‘appropriateness’ and score of each treatment. These were compared with the actual treatment the patient received. Over the study period, 585 patients (mean age: 6.5 years, 51% male, 49% female) were treated for type III supracon...
