Mean follow-up was 4 years. Ten patients underwent IFIS and the remaining 20 underwent RIF. The 2 groups showed no difference in demographics, grade of slip, deformity or presenting symptoms. Of 10 treated with IFIS, the SA reduced by a mean of 10 degrees and C7 sagittal vertical line changed by 31 mm. In the RIF cohort, SA reduced by 16 degrees and C7 sagittal vertical line reduced by 26 mm. PT was unchanged in both groups. In IFIS cohort, 2 patients showed postoperative weakness, resolved by 2 years. None required revision surgery. In the RIF group, 4 sustained dural tears and 1 a laminar fracture, 7 showed postoperative weakness or dysaesthesia, 3 of which had not resolved by 2 years. Eight patients underwent unplanned further surgery, 3 for pseudarthrosis.

RIF and IFIS show similar radiologic outcomes. RIF shows a higher rate of unplanned return to surgery, pseudarthrosis and persisting neurological changes.

Plate fixation has been the traditional technique for fracture repair of unstable ankle injuries with an associated lateral malleolus fracture. Recently, biomechanical and clinical data have demonstrated lag screw only fixation to be an effective alternative to plate fixation in the adult population. This comparison has yet to be studied in the adolescent or pediatric population. SU1498 in vivo The objective of this study was to compare lag screw only fixation with traditional plating for lateral malleolus fractures in adolescents.

A retrospective review was conducted of 83 adolescents with unstable oblique lateral malleolus fractures treated at a single pediatric level-1 trauma center between 2011 and 2019 with a minimum clinical follow-up until fracture union. Patients were divided into 2 surgical groups (1) plate fixation (n=51) or (2) lag screw fixation (n=32). Radiographic and clinical outcomes and complications were measured in both groups.

All patients in both groups achieved our primary outcome measure of fracl time and less symptomatic implants, lag screw only fixation should be considered as a viable treatment alternative to traditional lateral plating in the adolescent population.

Multiple epiphyseal dysplasia (MED) and pseudoachondroplasia (PSACH) are congenital skeletal disorders characterized by irregular epiphyses, mild or severe short stature and early-onset osteoarthritis which frequently affect the hips. The current study evaluates the long-term results of the Chiari osteotomy in MED and PSACH patients.

Twenty patients (14 MED and 6 PSACH) were retrospectively included. Clinical assessment used the Postel Merle d'Aubigné (PMA) score and the Hip disability and Osteoarthritis Outcome Score (HOOS). Risser index, Sharp angle, acetabular depth index, center-edge angle, Tönnis angle, and femoral head coverage were measured on the preoperative radiographs and at last follow-up. The Treble index, which identifies the hip at risk in MED patients, was also determined. Stulberg classification (grades I to V) was used to evaluate the risk of osteoarthritis in the mature hips.Statistical analyses determined differences between preoperative and postoperative data. The Kaplan Meier method was used to calculate the survival rate of the operated hips using total hip arthroplasty as the endpoint.

Thirty-three hips which underwent a Chiari osteotomy were reviewed. The average follow-up was 20.1 years. The PMA scores were significantly better at last follow-up than preoperatively. All radiographic parameters significantly improved. Moreover, the Sharp angle, center-edge angle, and femoral head coverage improved to a normal value at hip maturity. All of the operated hips had a Treble index of type I. At hip maturity, a majority of hip were aspherical congruent (Stulberg grades of III and IV). The survival rate of the operated hips was 80.7% at 24 years postoperative.

The Chiari osteotomy is a satisfying solution for severe symptomatic hip lesions in MED and PSACH patients. At long-term follow-up, this procedure lessens pain and improves hip function, which delays total hip arthroplasty indication.

Congenital femoral deficiency (CFD) is a rare condition that affects the morphology of the hip and surrounding soft tissues. Bony deformity and distorted muscular anatomy are well known, but no studies have described the relationship of the femoral neurovascular (NV) bundle to surgically relevant anatomic landmarks. The authors compared the location of the femoral NV bundle on the affected side in patients with CFD with the unaffected side. The authors hypothesized that the bundle on the pathologic side would be in an abnormal position relative to the unaffected side.

Thirty-three patients diagnosed with unilateral CFD who had undergone preoperative magnetic resonance imaging of the pelvis were included in our study. The authors identified the femoral NV bundle on the axial cuts and measured its distance from the anterior superior iliac spine (ASIS), anterior inferior iliac spine (AIIS), and lesser trochanter (LT). Anatomic percent change and absolute measurements were then compared and correlated with associated boney deformities and the Paley classification.

The distance from the femoral NV bundle to the ASIS, AIIS, and LT was significantly different compared with the unaffected side. The AIIS absolute distance and AIIS percent change significantly correlated with the neck-shaft angle of the proximal femur.

In patients with CFD, the femoral NV bundle seems to be further from the LT and closer to the AIIS on the affected side when compared with the unaffected side. magnetic resonance imaging may be helpful to understand the course of the femoral NV bundle before reconstruction in patients with CFD; however, the authors recommend identification of the femoral NV bundle before transection of the proximal rectus femoris tendon to provide safe surgical care.

Level IV-case-control study of diagnostic studies.

Level IV-case-control study of diagnostic studies.99mTc-bisphophonates bone scan, planar and single-photon emission computed tomography/computed tomography (SPECT/CT) modalities, is a commonly used technique that provides high sensitivity and specificity for detection of osseous metastases. However, besides bone metastases, SPECT/CT provides an accurate evaluation of the localization of the lesions and supplies anatomic information that can be valuable for diagnosis of nonmalignant bone diseases, occasionally disclosed in the skull. Reporting of craniofacial lesions detected by 99mTc-MDP (99mTc-labeled methylene diphosphonate) bone scintigraphy and SPECT/CT in the literature is limited. The aim of this pictorial review is to present the findings detected by 99mTc-MDP bone scintigraphy and SPECT/CT including cases under two broad categories osteoblastic and hyperostosis craniofacial lesions.
