Introduction

This study compares outcomes of vertebroplasty(VP) and kyphoplasty(KP) in 125 consecutive female Asian patients above 65 years with L1 osteoporotic vertebral compression fractures

Methods

57 and 68 patients underwent VP and KP respectively from 2004 to 2008. Outcomes were measured prospectively at pre-operation, 1 month, 6 months and 2 years post-operation by blinded assessors. Radiographic outcome: Anterior, middle and posterior vertebral heights of the L1 vertebral body Functional outcome: Short-Form 36(SF-36) score, Visual Analogue Scale(VAS) score for back pain

Introduction

The risk factors for new adjacent vertebral compression fracture (NAVCF) after Vertebroplasty (VP) or Kyphoplasty (KP) for osteoporotic vertebral compression fractures (VCFs) were investigated.

Materials and methods

The authors retrospectively analyzed the incidence of NAVCFs in 135 patients treated with VP or KP for osteoporotic VCFs. Study period was from 2004 to 2008 with minimum follow-up of 2 years.

Possible risk factors were documented: age, gender, body mass index, bone mineral density (BMD), co-morbidities, location of treated vertebra, treatment modality and amount of bone cement injected.

Anterior-posterior vertebral body height ratio, intra-discal cement leakage into the disc space and pattern of cement distribution of the initial VCF and adjacent vertebral bodies were assessed on lateral thoracolumbar radiographs by 2 independent assessors.

Distraction osteogenesis (callotasis) has been widely used in patients with limb-length inequality or massive bone defects. This procedure, however, may be associated with a high incidence of physical and psychosocial complications. Callotasis telescoping on a locked intramedullary nail has been used to shorten the period of external fixation. Little attention has been given to the use of locked intramedullary nails in the treatment of complications after callotasis.

Between 1990 and 1999, we used locked intramedullary nailing in 27 patients for the treatment of complications after distraction osteogenesis. There were 17 men and ten women with a mean age of 33.2 years (16 to 66). The nail was inserted at a mean of 3.4 weeks (0 to 15) after removal of the external fixator. Simultaneous autogenous bone grafting and soft-tissue reconstruction were also undertaken in seven and two patients, respectively.

There was consolidation of the callus or docking site in all patients at a mean of 6.4 months (2 to 14) after surgery. The mean shortening of the callus was 0.7 cm (0 to 2.5). Two patients had infection at the site of a distal screw which resolved after removal of the nail. In 17 patients the nail was removed at a mean of 26 months after its insertion.

Locked intramedullary nails are useful in treating complications after distraction osteogenesis in skeletally mature patients. The risk of infection should be borne in mind.
