Background

Periprosthetic joint infection (PJI) is a devastating complication and interest exists in finding lower cost alternatives to current management strategies. Current strategies include a two-stage revision with placement of an antibiotic spacer and delayed placement of a new arthroplasty implant. This study aimed to show that biofilm residue can be reliably eradicated on infected implants, safely allowing re-implantation in a spacer.

Methods

Strains of Staphylococcus aureus MRSA252 or Staphylococcus epidermidis RP62A were grown on cobalt-chrome discs. For each strain, discs were divided into 5 groups (5 discs each) and exposed to several sterilization and biofilm eradication treatments: (1) autoclave, (2) autoclave + sonication; (3) autoclave + saline scrub; (4) autoclave + 4% chlorhexidine (CHC) scrub; and (5) autoclave + sonication + CHC scrub. Sterilization and biofilm eradication were quantified with crystal violet assays and scanning electron microscopy (SEM).

Background: Satisfaction following anterior and/or posterior spinal fusion varies greatly between individuals. The aim of this study was to assess patient satisfaction with the post-operative scars following surgical correction of scoliosis.

Methods: Prospective study; 31 patients (range 10–37 years), minimum of 2 months post-operation, interviewed in clinic or over the telephone using a questionnaire.

Results: Overall, 18 (58%) patients were disappointed with their scar; it was not what they expected, Patients with anterior scars or both anterior and posterior scars were the most disappointed groups.

39% of patients felt they were inadequately informed or not informed of the nature of scar. However, over 50% of those who had a specialist spinal nurse (SSN) consultation reported the scar to be as they expected. Scar length was the main source of disappointment. 55% reported their scars as being raised (keloid), particularly at the ends. Scar colour and shape was an issue for 23%, whilst 39% experienced prolonged healing. 19 patients had a pre-op consultation with the SSN, 11 did not get this opportunity, 1 declined.

Conclusion: Clearly there’s a need for improved education and understanding with regard to the nature of the scoliosis surgical scar(s). Input from a SSN is important and surgeons must clarify exactly what they mean when discussing operations with patients. This could be done with the aid of pictograms or leaflets detailing issues discussed in consultations along with the opportunity to meet patients who have already had surgery. These measures may lead to increased patient satisfaction with surgery.
