KEEP EXPLORING
In the year 2000 the rate of infection after arthroplasty in our hospital was 9.75% and methicillin-resistant Staphylococcus aureus (MRSA) was the organism in 33% of the infected joints. In an attempt to overcome this unacceptable situation, we changed our prophylaxis regime over a period of 6 months. This involved modifying the precautionary measures for preventing surgical infections, active prophylaxis against any nasal reservoir of infection in joint implant patients, the control of health care personnel, the strict application of standard and contact precautions in all patients with MRSA, and the use of teicoplanin as prophylaxis during this 6-month period. This resulted in a definite decrease in the incidence of orthopaedic wound infections by MRSA, while the level of MRSA infection elsewhere in the hospital remained constant. Only one infection was detected during this 6-month trial, and this beneficial effect was maintained during the following 6 months. Since then, only sporadic new infections have been detected. Patients with arthroplasties performed during the study were followed for 12 months, and no new cases of MRSA infection were detected.
OBJECTIVES: Many hospitals in New Zealand have been using clinical priority assessment criteria (CPAC) to select and prioritize patients for access to publicly funded elective surgery. CPAC usually consist of clinical, patient-experienced, and social measures. The objective of this study was to determine how robust patient rankings were and the extent to which the patients selected were those who benefited the most from surgery. METHODS: Patients prioritized for cataract (n = 101), prostate (n = 103), and hip or knee joint replacement (n = 137) surgery according to CPAC were assessed using the EQ-5D, SF-12, and condition-related patient-experienced health status measures before and after treatment. Correlations between the rankings of patients on the CPACs and the alternative instruments were explored. RESULTS: For each surgery group, the CPAC ranking of patients was not strongly correlated with rankings obtained using their before-treatment EQ-5D (valued) profiles or the SF-12, although there was some correlation with rankings according to the condition-related measures. Improvements in the health status of patients who were operated on, as measured by the change in their EQ-5D values, were poorly correlated with equivalent changes on the SF-12 and condition-related measures. Patients' baseline health status according to the CPAC, the EQ-5D, and the SF-12 patient-experienced measures was only slightly related to the magnitude of benefit following surgery. The strongest predictors of improvement in health status were the baseline condition-related measures. CONCLUSIONS: The current method of prioritizing patients in New Zealand requires reconsideration, although a gold standard method for prioritization is not immediately apparent from these results.
OBJECTIVE: The purpose of this study was to investigate the results of performing a lateral pterygoid myotomy with reattachment to the condylar stump to restore more normal function after total joint reconstructive surgery. STUDY DESIGN: Twenty-four joints were reconstructed in 14 patients with stock Christensen chrome-cobalt prostheses. Patients were separated into 2 groups. Group I consisted of 4 joints without reattached lateral pterygoid muscle (-LPM), and group II consisted of 20 joints with reattachment of the lateral pterygoid muscle to the condylar stump (+LPM). Patients were evaluated at an average of 15 months postoperatively to assess mandibular movement. Group I was compared with group II, and statistical analysis was performed through the use of the Mann-Whitney test. Patient satisfaction was evaluated by using postoperative questionnaires. RESULTS: Group II had an average interincisal opening 7.3 mm greater than Group I (P <.001). Lateral movements averaged 3.86 mm in Group II versus 0.5 mm in Group I (P <.05). Protrusion was 2.83 mm greater in Group II than in Group I (P = 0.53). CONCLUSION: The reattachment of the lateral pterygoid muscle to the condylar stump during total joint reconstructive surgery may provide the patient with greater interincisal opening, lateral excursions, and protrusive movement. The preliminary data from these small, nonrandomized groups are promising for improved function following total joint reconstruction.
