Anatomic and isometric points on femoral attachment site of popliteus muscle-tendon complex for the posterolateral corner reconstruction.

Study Design: Descriptive laboratory study.

Purpose: The femoral anatomic insertion site and the optimal isometric point of popliteus tendon for posterolateral reconstruction are not well known. Purpose of this study was to determine the relative relationship between the femoral anatomic insertion and isometric point of popliteus muscle-tendon complex with the lateral epicondyle of femur.

Accuracy and safety of pedicle screw placement in neuromuscular scoliosis with free-hand technique.

It is a retrospective analytic study of 1,009 transpedicular screws (689 thoracic and 320 lumbosacral), inserted with free-hand technique in neuromuscular scoliosis using postoperative CT scan. The aim of paper was to determine the accuracy and safety of transpedicular screw placement with free-hand technique in neuromuscular scoliosis and to compare the accuracy at different levels in such population. All studies regarding accuracy and safety of pedicle screw in scoliosis represent idiopathic scoliosis using various techniques such as free-hand, navigation, image intensifier, etc.

Treatment of neuromuscular scoliosis with posterior-only pedicle screw fixation.

Background: To determine whether posterior-only approach using pedicle screws in neuromuscular scoliosis population adequately addresses the correction of scoliosis and maintains the correction over time.

Methods: Between 2003 and 2006, 26 consecutive patients (7 cerebral palsy, 10 Duchenne muscular dystrophy, 5 spinal muscular atrophy and 4 others) with neuromuscular scoliosis underwent posterior pedicle screw fixation for the deformity. Preoperative, immediate postoperative and final follow-up Cobb's angle and pelvic obliquity were analyzed on radiographs.

Callus patterns in femur lengthening using a monolateral external fixator.

Objective: We studied the callus pattern seen in femoral lengthening using monolateral external fixator to determine whether callus types and shapes can predict the final outcome of the procedure.

Material And Methods: The radiographs of 41 cases of femoral lengthening (33 unilateral and 8 bilateral) in 33 patients with a mean age 11.9 years (range 4-22 years) were retrospectively analysed by four observers and classified into different shapes and types in concordance with the Ru Li classification.
