A new method for reduction quality assessment in acetabular fractures: acetabular congruency measurement.

Introduction: The determination of adequate reduction is difficult perioperatively due to inadequate radiographic scanning and objective measurement methods. The purpose of the present study is to evaluate an objective measurement of the weight bearing acetabular dome congruency. The sensitivity and specificity of 2 measurement methods after acetabular fracture fixation are compared.

The Central Dislocation of Femoral Head in the Transverse and Both Column Acetabular Fractures: Is It Really Medialized?

Purpose: We hypothesized that the central dislocation of the femoral head does generally not occur in transverse acetabular fractures, although it does usually occur in both column fractures.

Materials And Methods: Fifty-two transverse and both column acetabular fracture cases were evaluated retrospectively. The distances between (a) the sciatic notch on the fracture side and the vertical axis of the pelvis (VA line) and (b) the contralateral intact sciatic notch and the VA line were measured.

Methods: Fifty-one transverse-oriented acetabular fracture cases admitted between 1999 and 2013 were evaluated retrospectively. Comparative studies were performed for groups organized by acetabular fracture type, degree of sacroiliac separation, and postoperative reduction quality .

Distal fusion level selection in Lenke 1A curves according to axial plane analyses.

Background Context: In adolescent idiopathic scoliosis (AIS), identification of curve patterns and determination of fusion levels are most important for correcting deformity, improving trunk balance, and saving motion segments. Lenke 1A scoliosis is the most common type of AIS, accounting for around 16% of all AIS; however, how to determine the lower instrumented vertebrae in this common curve type is unclear.

Purpose: The aim was to classify Lenke 1A curves according to lumbar axial plane analyses to determine optimal distal fusion level selection.

External rotator sparing with posterior acetabular fracture surgery: does it change outcome?

Management of acetabular fractures with modified posterior approach to spare external hip rotators.

Introduction: In the present study the quality of reduction and incidence of complications in hip external rotator sparing modified posterior approach was assessed in both simple and complex acetabular fractures.

Materials And Methods: This retrospective study includes 37 patients (38 hips) with a mean age of 42.1 years (range 21-60), that had been treated for displaced acetabular fractures from June 2007 through May 2011.

Percutaneous fixation of anterior column acetabular fracture in a renal transplant recipient.

Renal transplantation, performed per million population, ranges from 30 to 60 in developed countries. The transplanted kidney is generally placed in iliac fossa; therefore the treatment procedure of the pelvic trauma in these patients should be selected carefully. The gold standard technique for the treatment of displaced acetabulum fractures is open reduction and internal fixation.

Utility of the omentum in sacral reconstruction following total sacrectomy due to recurrent and irradiated giant cell tumour of the spine.

Reconstruction of the lumbosacral region after surgical excision of irradiated and recurrent spinal giant cell tumours remains a challenging problem. In this case report, we describe the use of the pedicled omentum flap in reconstruction of an irradiated and infected wide sacral defect of a 19-year-old male patient. The patient had radiotherapy and subsequent wide surgical resection after recurrence of the tumour.

The height gain in scoliotic deformity correction: assessed by new predictive formula.

Height gain after scoliosis correction is of a special interest for the patient and family. Ylikoski was the first to suggest a formula predicting height loss in untreated scoliotic patients. Stokes has recently suggested a new formula by using Cobb angle to determine height loss in idiopathic curves.

Outcome in early adolescent idiopathic scoliosis after deformity correction: assessed by SRS-22, psychometric and generic health measures.

The purpose of this study was to examine the health status of early adolescent patients with idiopathic scoliosis using depression-anxiety scales, a generic Quality-of-Life Inventory as well as the Scoliosis Research Society-22 (SRS-22) questionnaire to search for the most comprehensive approach for the measurement of outcomes. Thirty-seven early adolescent patients with idiopathic scoliosis were analyzed within 6-12 months of the postoperative time period. There was no statistically significant correlation between the total score of SRS-22 and the total scores of the pediatric quality-of-life inventory.

Study Design: Retrospective study.

Objective: Investigate the radiographic features of the subtypes of Lenke 1A curves to help to determine the optimum distal fusion level selection.

Summary Of Background Data: The Lenke 1A was the most frequently evaluated curve type in adolescent idiopathic curves.

Isolated pedicle screw instrumented correction for the treatment of thoracic congenital scoliosis.

Study Design: Retrospective study.

Objective: To evaluate the radiologic results of fusion with segmental pedicle screw fixation in neglected thoracic congenital curves with a mean follow-up of 51.3 months (range: 24 to 108 mo).

Evaluation of thoracic pedicle screw placement in adolescent idiopathic scoliosis.

Pedicle screw fixation is a challenging procedure in thoracic spine, as inadvertently misplaced screws have high risk of complications. The accuracy of pedicle screws is typically defined as the screws axis being fully contained within the cortices of the pedicle. One hundred and eighty-five thoracic pedicle screws in 19 patients that were drawn from a total of 1.

An unusual type of lateral compression injury of the pelvis tilt fracture with anterior displacement.

Tilt fracture is the most unusual variant of pelvic lateral compression injury. The major problem was reported to be protrusion of the pubic ramus into the perineum by posterior-inferior displacement of the fragment. Tilt fragment with anterior and inferior displacement has not been reported in English speaking literature to our knowledge.

A case of traumatic dislocation of the first metatarsophalangeal joint with concomitant fibular sesamoid fracture and thoracic vertebral fracture is presented. The first metatarsophalangeal joint was repaired by means of open reduction with collateral ligament repair. At 12 months following the operation, the patient displayed nonpainful and unrestricted first metatarsophalangeal joint motion.

Placement of pedicle screws in thoracic idiopathic scoliosis: a magnetic resonance imaging analysis of screw placement relative to structures at risk.

In posterior pedicle screw instrumentation of thoracic idiopathic scoliosis, screw malposition might cause significant morbidity in terms of possible pleural, spinal cord, and aorta injury. Preoperative axial magnetic resonance images (MRI) in 12 consecutive patients with right thoracic adolescent scoliosis, all with King type 3 curves, were analyzed in order to evaluate the relationship between the inserted pedicle screw position to pleura, spinal cord, aorta. Axial vertebral images for each thoracic level were scanned and the simulation of pedicle screw insertion was performed using a digital measurement programme.

Pedicle morphology of the thoracic spine in preadolescent idiopathic scoliosis: magnetic resonance supported analysis.

Although several studies have been reported on the adult vertebral pedicle morphology, little is known about immature thoracic pedicles in patients with idiopathic scoliosis. A total of 310 pedicles (155 vertebrae) from T1 to T12 in 10-14 years age group were analyzed with the use of magnetic resonance imaging and digital measurement program in 13 patients with right-sided thoracic idiopathic scoliosis. Each pedicle was measured in the axial and sagittal planes including transverse and sagittal pedicle width and angles, chord length, interpedicular distance and epidural space width on convex and concave sides of the curve.

The use of combined lateral and medial releases in the treatment of post-traumatic contracture of the elbow.

Elbow stiffness is a common disorder, which restricts daily activities. Between 30 degrees and 130 degrees of elbow movement is usually enough to perform most daily activities. However, a 10 degrees to 15 degrees loss of elbow extension may be a problem when the patient is an athlete.
