The contents of 3 orthopaedic journals [JBJS (Am), JBJS (Br) and CORR] during 2001 and 2011 were compared for publication bias. There were total of 2028 articles. After exclusion 1662 scientific articles were analysed for statistical results, clinical conclusion, sub-speciality topics studied, the geographical region the study been conducted and the statistical method used. The articles classified into 7 categories: THR, TKR, Basic sciences, Trauma, Spinal disorders, Paediatric disorders and Tumour. 91% of articles on THR and 95% of articles on TKR were positive studies in 2001. Articles dealing with trauma had the lowest proportion of positive studies (74%) as compared to all other topics. We noted that JBJS (Br) published more negative studies as compared to JBJS (Am) and CORR. In 2011 less articles on THR and TKR had positive studies (68% and 76% respectively). Spinal surgery articles report less number of non significant studies nowadays (24% in 2001 and 2% in 2011). There is a significant change in the trend towards reporting more negative studies in relation with THR and TKR (p < 0.05). Articles dealing with Basic sciences, Trauma, Paediatric disorders and Tumour did not have any significant change in reporting negative studies in the last decade. Significant findings in spinal disorders were 3.8 times more likely to be published than non significant stdies. Overall, JBJS (Br) continued to publish more negative studies as compared to JBJS (Am) and CORR. Journals seem to prefer reporting more significant results with spinal disorders and more non significant results in relation with Hip and Knee arthroplasty in last ten years. This might be because of authors' perceptions of the importance of their findings and journals preferences for significant results.
In the current climate of increasing financial pressures and reducing bed numbers, a predictor of length of stay (LOS) may have a bearing on hospital finances. Independent sector treatment centres may also skew the ASA grade and co-morbidity of the patient group treated in a hospital setting. We performed a study of 100 consecutive patients undergoing Total hip or knee arthroplasty between April and September 2006. Median age was 71 years (35 – 88) with 75% of patients having significant (cardiac, renal or respiratory) pre-existing medical conditions (24% with 3 or more conditions). Average ASA grade was 2 (15% grade 3) and average BMI was 30. A significant reduction in LOS from 8.47 to 5.87 days was seen in under 70 year olds when compared with those over 70 years (p = 0.0004), having 3 or more co-morbidities (compared with 2 or less) increased average LOS from 6.61 days to 9.3 days (p = 0.002), ASA grade of 3 increased LOS to 9.56 days from 6.27 and 6.87 for grade 1 and 2 respectively (p = 0.014) and living alone (compared with cohabiting) increased LOS from 6.55 days to 9.19 days (p = 0.0017). However no statistical significance was seen for BMI with an average of 7.19 days for <
30 and 7.37 days for patients with BMI of 30 or above (p = 0.82) Regardless of this patient group being elderly and obese with significant co-morbidity, an acceptable outcome was seen, with 70% of patients discharged within 7 days and only 4% staying >
14 days. Although BMI did not predict outcome, number of co-morbidities, ASA, age greater than 70 years and living alone all demonstrated a significant increase in LOS. Increased resources in this at risk group within a pre-admission setting could reduce length of hospital stay.
Proximal tibial epiphyseal injuries are rare. Reported incidence varies from 0.5 – 3% of epiphyseal injuries. Proximal tibial epiphysis is well protected unlike distal femoral epiphysis. Thus, the distal femoral injuries are 7 times more frequent than proximal tibial epiphyseal injuries. Case Report: 12-year old boy, hit a pole at the bottom of a dry ski slope and presented to A&
E within 20 minutes. He had a swollen, deformed knee and leg that was immobilised in a temporary splint. He had absent posterior tibial and dorsalis pedis pulses. Emergency manipulation under GA and further stabilised with K-wires, A/K Back Slab in 450 flexion. Distal pulses returned on table. K-wires were removed after 4 weeks and physiotherapy started. At 3 months, he was back to normal activities except sports. At 2 years, he was longer by 1 cm in left tibia, valgus of 120 at the knee, full ROM, no ligament laxity and reports occasional anterior knee pain. Discussion: Posteriorly displaced proximal tibial Salter Harris II injuries are very rare. Emergency reduction and stabilisation, absence of popliteal artery tear had prevented the immediate complications. The late complications did not warrant a surgical intervention.
