We present a case series of patients who underwent 3 or 4 part proximal humerus fracture fixation using an intra-osseous suture technique. 18 patients are included in the study with follow up data obtained ranging from 1 to 4 years. Oxford Shoulder Scores (OSS) and range of movement measurements were taken for all patients.

The mean OSS for the group was 50/60 with a mean forward flexion of 140°, abduction of 132°, external rotation of 48° and internal rotation to the level 10^th thoracic vertebra. Three patients developed adhesive capsulitis, 2 requiring subsequent arthroscopic release. This data compares favourably to outcomes reported in the literature with hemiarthroplasty or locking plate fixation.

An activity based costing analysis estimated that the treatment costs for proximal humerus fractures was approximately £2,055 when performing a soft tissue reconstruction, £3,114 when using a locking plate and £4,679 when performing a hemiarthroplasty. This demonstrates a significant financial saving when using intra-osseous fixation compared to other fixation techniques.

We advocate the use of the intra-osseous suture fixation technique for certain 3 and 4 part fractures. It gives good functional outcomes, significant cost savings and potentially makes revision procedures easier when compared to other fixation techniques.

We evaluated the quality of guidelines on thromboprophylaxis in orthopaedic surgery by examining how they adhere to validated methodological standards in their development. A structured review was performed for guidelines that were published between January 2005 and April 2013 in medical journals or on the Internet. A pre-defined computerised search was used in MEDLINE, Scopus and Google to identify the guidelines. The AGREE II assessment tool was used to evaluate the quality of the guidelines in the study.

Seven international and national guidelines were identified. The overall methodological quality of the individual guidelines was good. ‘Scope and Purpose’ (median score 98% interquartile range (IQR)) 86% to 98%) and ‘Clarity of Presentation’ (median score 90%, IQR 90% to 95%) were the two domains that received the highest scores. ‘Applicability’ (median score 68%, IQR 45% to 75%) and ‘Editorial Independence’ (median score 71%, IQR 68% to 75%) had the lowest scores.

These findings reveal that although the overall methodological quality of guidelines on thromboprophylaxis in orthopaedic surgery is good, domains within their development, such as ‘Applicability’ and ‘Editorial Independence’, need to be improved. Application of the AGREE II instrument by the authors of guidelines may improve the quality of future guidelines and provide increased focus on aspects of methodology used in their development that are not robust.
