Three-staged correction of severe rigid idiopathic scoliosis using limited halo-gravity traction

Introduction

Despite the advantages of modern instrumentation techniques, the treatment of severe rigid idiopathic scoliosis could be very demanding. Traction can provide better, safer correction and minimize complications related to forceful intra-operative maneuvers; however, several side effects are associated with prolonged periods of traction. The aim of this work is to review the clinical and radiographic results of limited perioperative halo-gravity traction in severe rigid curves analyzing its efficacy, advantages and possible complications and comparing it to classic two staged corrections performed without traction.

Methods

A retrospective case control study including 47 adolescents with severe rigid idiopathic scoliosis divided into two groups; a consecutive series of 21 patients who had a three-staged correction by an anterior release, 2 weeks of halo-gravity traction then posterior instrumentation (TRN group); compared to an earlier series of 26 consecutive patients treated without traction (SAP group). The average age was 18 years + 1 month and 16 years + 2 months, respectively. The average preoperative dorsal and lumbar curves for (TRN) group were 106.5° and 87°, respectively, and for (SAP) group were 102° and 81°, respectively.

Results

Patients were followed up for an average of 6 years (range 3–8 years). A significantly better correction was achieved in (TRN) group (average 59%) compared to (SAP) group (average 47%). At final follow-up, the loss of correction had an average of 8° for (TRN) group and 11° for (SAP) group. A shorter hospital stay was found in (SAP) group; a shorter operative time was found in (TRN) group and there was no significant difference in blood loss, early or delayed complications.

Conclusions

Limited halo-gravity traction is an efficient, safe modality in the treatment of severe rigid adolescent scoliosis. The application of gradual traction over a limited period of 2 weeks led to better correction, shorter operative time with no significant complications.     

The impact of halo-gravity traction on curve rigidity and pulmonary function in the treatment of severe and rigid scoliosis and kyphoscoliosis: a clinical study and narrative review of the literature

Introduction  

The treatment of rigid and severe scoliosis and kyphoscoliosis is a surgical challenge. Presurgical halo-gravity traction (HGT) achieves an increase in curve flexibility, a reduction in neurologic risks through gradual traction on a chronically tethered cord and an improvement in preoperative pulmonary function. However, little is known with respect to the ideal indications for HGT, its appropriate duration, or its efficacy in the treatment of rigid deformities.

Halo-股骨髁上牵引对重度脊柱侧凸后路矫形的影响

目的探讨Halo-股骨髁上牵引对重度先天性脊柱侧凸及特发性脊柱侧凸患者后路矫形效果的影响。方法选取60例重度脊柱侧凸患者分为先天性脊柱侧凸组及特发性脊柱侧凸组,每组30例。CS组术前平均冠状面Cobb角、胸椎后凸分别为95．7°及70．2°。IS患者术前平均冠状面Cobb角、胸椎后凸为91．6°及50．6°。平均随访38个月。结果60例患者平均牵引23d,平均牵引重量16kg。IS组患者Halo牵引及后路矫形术后侧凸矫正率分别达39．3％、57．5％,胸椎后凸平均矫正33．7％。CS组Halo牵引及后路矫形术后侧凸矫正率分别达35．3％、45．2％,胸椎后凸平均矫正43．5％。两组患者后路矫形术后侧凸及后凸矫正率差异均有统计学意义（P〈0．05）。4例患者在牵引过程中并发臂丛神经麻痹,神经功能均在2个月内获得完全恢复。结论Halo-股骨髁上牵引可大幅提高脊柱侧凸尤其是特发性脊柱侧凸畸形矫正疗效。     

Brachial plexus palsy caused by halo traction before posterior correction in patients with severe scoliosis

OBJECTIVE: To explore the clinical features and treatment results of brachial plexus palsy caused by halo traction before posterior correction in patients with severe scoliosis. METHODS: A total of 300 cases of severe scoliosis received halo traction before posterior correction in our department from July 1997 to November 2004. Among them, 7 cases were complicated with brachial plexus palsy. The average Cobb angle was 110 degree (range, 90 degree-135 degree). Diagnoses were made as idiopathic scoliosis in 1 case, congenital scoliosis in 3 cases, and neuromuscular scoliosis in 3 cases. Additionally, diastematomyelia and tethered cord syndrome were found in 3 cases and thoracolumbar kyphosis in 2 cases. Weight of traction was immediately reduced when the patient developed any abnormal neurological symptoms in the upper extremity, and rehabilitation training was undertaken. Simultaneously, neurotrophic pharmacotherapy was applied, and the neurological function restoration of the upper limbs and the recovery time were documented. RESULTS: Traction was used for an average of 3.5 weeks (range, 2-6 weeks) before spinal fusion for these 7 patients. The average traction weight was 8 kg, which was 19% on average (range, 13%-26%) of the average body weight (40.2 kg). These 7 patients had long and thin body configuration with a mean height of 175 cm. The duration between symptoms of brachial plexus paralysis and the diagnosis was 1-3 hours. All of these 7 patients presented various degrees of numbness in the ulnar side of the hand and forearm. Median nerve paresis was found in 3 cases and ulnar nerve paresis in 4 cases. Complete recovery of the neurological function had been achieved by the end of three months. CONCLUSIONS: The clinical features of brachial plexus palsy caused by halo traction include median nerve paresis, ulnar nerve paralysis, and numbness in the ulnar side of the hand and forearm, which may be due to the injury of the inferior part of the brachial plexus, i.e., damage of C8 and T1 nerve roots. Complete recovery of neurological function can be expected when the patient is kept under careful observation for recognizing this complication as soon as possible, then immediately reducing or removing the traction weight, and adopting rehabilitation training and neurotrophic pharmaceutical treatment.

Efficacy of growth hormone therapy for patients with skeletal dysplasia

Most patients with skeletal dysplasia show severe short stature. Surgical therapy has been attempted to correct bone deformities, but therapy for improving their severe short stature has been rarely attempted. We undertook a clinical trial of growth hormone (GH) therapy for patients with skeletal dysplasia accompanying severe short stature caused by achondroplasia (ACH), hypochondroplasia (HCH), pseudoachondroplasia (PSACH), spondyloepiphyseal dysplasia congenita (SED), or Schmid type metaphyseal dysplasia (MD). This study examined the efficacy of GH therapy on height increase and change of height SD score over a 1-year period in patients with skeletal dysplasia and showed a short-term efficacy for skeletal dysplasia. In ACH, HCH, and MD, GH had a significant effect on height gain. However, PSACH and SED showed no height gain efficacy; in cases of PSACH, height SD score was worse after therapy. Severe adverse events were not observed except in one SED case, in which scoliosis worsened and height did not increase. For patients with skeletal dysplasia, GH therapy is moderately effective for height gain. It is ineffective in cases with severe spinal deformities, however; although bone growth was promoted, the ligaments and matrix were too weak to support muscle tonus and the effects of gravity, resulting in worsened kyphosis and lordosis. These results clarify why GH therapy is ineffective for height gain. The pathogenic genes of skeletal dysplasia have recently been detected and consequently changes in bone formation have been investigated in detail. Careful consideration of indications for therapy and cautious observation during therapy are crucial when attempting to treat advanced bone deformities.
