Although the primary defect of Duchenne muscular dystrophy has been found, there is no causal treatment to alter the natural course of this disease. Based on the recommendations by Glorion and Rideau with early treatment of contractures of the hips and the lower limbs we performed a modified release of the spina muscles, resection of tensor fasciae latae muscle and a lengthening of the tendo calcaneus in 32 patients. The mean age of
DMD
patients at time of operation was 6.1 years. The mean follow-up was 3.4 years. All children underwent mobilisation the day after surgery. Complete correction of all contractures was immediately achieved after operation and kept in all but two cases up to the follow-up examination after 3.4 years. No loss of ambulation was observed. Our results demonstrate that early selective surgery in
DMD
patients just at or better before the onset of contractures without performing an additional aponeurectomy of the iliotibial band and percutaneous tenotomy of the hamstrings according to the original Glorion-Rideau technique safely prevents severe contractures and thereby delays the progression of
scoliosis
.

This study is designed to analyse the behavior, in the sagittal plane, of a complete human dorso-lumbar rachis, made rigid by the posterior instrumentation used for the treatment of
scoliosis
, on subjects suffering from
DMD
(Duchenne Muscular Dystrophy). The object of this analysis is to demonstrate the reliability of early surgery made possible by new instrumentation. Close review of the literature shows that the currently used Harrington or Luque instrumentations lead to mechanical complications, especially rod breaking, at the thoraco-lumbar junction. 8 specimens were non-destructively tested in-vitro. Compression and flexion were applied. For each test, rachis movements with and then without instrumentation, and also rod restraints were noted. The results show a linear stiffness multiplied by 8.3 in flexion and 11.6 in extension. The maximum restraint recorded for physiological displacements is 77 MPa. This remains largely under the fatigue-breaking limit of the metal used (stainless steel hammer-hardened 316 L, Young's modulus = 200,000 MPa, Poisson's ratio = 0.21, endurance limit = 350 MPa at 5 x 10(6) cycles). The results of this study encourage us to continue and develop early surgery in children affected by myopathy, with fixation of the complete rachis, including a lumbo-sacral arthrodesis and a supple dorsal part of the mounting, in the sagittal plane.

A total of 36 consecutive nonambulatory
DMD
patients underwent
scoliosis
surgery. Patients were divided into two groups: the autogenous iliac crest bone graft group (the ICBG group; 20 patients) and the allogenous bone graft group (the ALBG group; 16 patients). The mean preoperative curves measured 87 degrees and 31 degrees at the last follow-up in the ICBG group and 83 degrees and 28 degrees in the ALBG group. In the ICBG group, three (15%) patients had intraoperative sacroiliac joint penetration, five (25%) had iliac crest inner cortex penetration and three (15%) had postoperative prolonged wound drainage at the donor site. At three months after surgery, donor site pain caused by bone harvest was found in 50% with severe pain limiting their physical function and causing difficulties in sitting in a wheelchair in 40% of the patients, whereas patients in the ALBG group returned to their preoperative level of function soon after surgery.

The objective of this investigation was to determine the outcome of spine fusion for neuromuscular (NM)
scoliosis
, using Unit Rod technique, with emphasis on complications related to preoperative general health. Between 1997 and 2007, 96 consecutive patients with neuromuscular
scoliosis
operated on with Unit Rod instrumentation were retrospectively reviewed. The inclusion criteria were diagnosis of NM
scoliosis
due to cerebral palsy (CP) and muscular dystrophy (
DMD
). Patient's preoperative general health, weight, and nutrition were collected. Different radiographic and clinical parameters were evaluated. There were 66 CP patients (59 nonwalking) and 30
DMD
patients (24 nonwalking). Mean age at surgery was 16.5 years and 13.9 years, respectively. All radiographic measurements improved significantly. Wound infection rate was 16.7% (11% of reoperation rate in CP; 10% in
DMD
; 3 hardware removal cases). No pelvic fracture due to rod irritation was observed. Unit Rod technique provides good radiographic and clinical outcomes even if this surgery is associated with a high complication rate. It is a quick, simple, and reliable technique. Perioperative management strategy should decrease postoperative complications and increases outcome. A standardized preoperative patient evaluation and preparation including respiratory capacity and nutritional, digestive, and musculoskeletal status are mandatory prior to surgery.
