Practice variation may occur when there is no standardised approach to specific clinical problems and there is a lack of scientific evidence for alternative treatments. Practice variation suggests that a segment of the patient population may be managed sub-optimally, and indicates a need for further research in order to establish stronger evidence-based practice guidelines. We surveyed Australian orthopaedic surgeons to examine practice variation in common orthopaedic presentations. In February 2009, members of the Australian Orthopaedic Association were emailed an online survey, which collected information regarding experience level (number of years as a consultant), sub-specialty interests, state where the surgeon works, on- call participation, as well as five common (anecdotally controversial) orthopaedic trauma cases with a number of management options. Surgeons were asked to choose their one most likely management choice from the list provided, which was either surgical or non-surgical in nature. A reminder was sent two weeks later. Exploratory regression was modeled to examine the predictors of choosing surgical management for each case and overall. Of 760 surgeons, 358 (47%) provided responses. For undisplaced scaphoid fractures, respondents selected short-arm cast (53%), ORIF (22%), percutaneous screw (22%) and long-arm cast (3%). Less experienced (0 to 5 years) (p=0.006) and hand surgeons (p=0.008) were more likely to operate. For a displaced mid-shaft clavicle fracture, respondents selected non-operative (62%), plating (31%) and intramedullary fixation (7%). Shoulder surgeons were more likely to operate (p<0.001). For an undisplaced Weber B lateral malleolus fracture, respondents selected plaster cast or boot (59%), lateral plating (31%), posterior plating (9%) and no splinting (2%). For a displaced

Background. One of the prime concerns when managing patients in plaster casts is loss of reduction. There have been studies showing that proper moulding of the plaster cast is critical in maintaining reduction. Recent studies have negated concerns that fibreglass (FG) casts do not allow swelling, when compared to plaster of Paris (POP) casts. However, their potential in maintenance of reduction has not been investigated. Materials and methods. We compared the three-point bending properties of FG casts with POP casts over the first 48 hours. The effect of splitting the casts, at one hour and 24 hours, was studied. Three identical jigs with hinged metal rods were designed to simulate a
Purpose of the study: Within the framework of a regional study, we compared the efficacy of pinning using the PY technique and the Kapandji method for the treatment of fractures of the distal radius with posterior displacement. Material and methods: This was a prospective study designed as a phase III randomised therapeutic trial in parallel groups. An open monocentric study with multiple operators compared the PY and Kapandji techniques. Two comparable groups were established: the PY group and the Kapandji group (K) for which we measured: quality of reduction using the radiographic frontal and sagittal radial inclination (FRI and SRI), radial length and inferior radioulnar index. Objective and subjective functional outcome assessed range of motion and the DASH and Jakim scores. The quality of the intra-articular reduction of articular fractures was assessed arthroscopically at the time of implant removal during the sixth week. Results: The series included 97 patients followed for one year. The preoperative FRI was 15.17 with mean posterior shift of −19.2. At one year, the RI was 25.5 in the PY group versus 22.6 in the K group (p=0.009) and the SRI 10.5 in the PY group versus 3.7 in the K group (p=0.04). For fractures with a posteromedian fragment and Gerard-Marchand fractures, the DASH at one year was 2 in the PY group versus 32 in the K group. The Jakim score was 71 in the PY group versus 58 in the K group (p=0.03) for posteromedian fragment fractures. The arthroscopic control at six weeks of articular fractures did not reveal any significant difference in intra-articular reduction. There were no tendon tears in this series. Discussion: This series shows the quality of pin fixation for wrist fractures, comparable with plating. It emphasizes the importance of adapting the type of pinning to the fracture type and the patient. Conclusion: Treatment of fractures of the distal radius with posterior displacement with pin fixation remains a treatment of choice, reserving PY osteosynthesis for fractures with a posteromedian fragment and Gerard-Marchand fractures and Kapandji osteosynthsis for simple

Introduction: Displaced
Fractures of the distal radius occurring in young adults are treated increasingly by open surgical techniques, partly because of concern that failure to restore the alignment of the fracture accurately may cause symptomatic post-traumatic osteoarthritis in future years. We reviewed 106 adults who had sustained a fracture of the distal radius between 1960 and 1968 and who were below the age of 40 years at the time of injury. We carried out a clinical and radiological assessment at a mean follow-up of 38 years (33 to 42). No patient had required a salvage procedure. While there was radiological evidence of post-traumatic osteoarthritis after an intra-articular fracture in 68% of patients (27 of 40), the disabilities of the arm, shoulder and hand (DASH) scores were not different from population norms, and function, as assessed by the Patient Evaluation Measure, was impaired by less than 10%. Ordinal logistic regression analysis showed a significant relationship between narrowing of the joint space and extra-articular malunion (dorsal angulation and radial shortening) as well as intra-articular injury. Multivariate analysis revealed that grip strength had fallen to 89% of that of the uninjured side in the presence of dorsal malunion, but no measure of extra-articular malunion was significantly related to either the Patient Evaluation Measure or DASH scores. While anatomical reduction is the principal aim of treatment, imperfect reduction of these fractures may not result in symptomatic arthritis in the long term, and this should be considered when counselling patients on the risks and benefits of the many treatment options available.
Sacral insufficiency fractures are traditionally treated with bed rest and analgesia. The importance of early rehabilitation is generally appreciated; but pain frequently delays this, resulting in prolonged hospital stay and the risk of complications related to immobility. We describe three women with sacral insufficiency fractures who were treated with percutaneous sacroiliac screws and followed up for a mean of 18 months (12 to 24). They had immediate pain relief, uncomplicated rehabilitation and uneventful healing.
We studied prospectively the regional inflammatory response to a unilateral distal radial fracture in 114 patients at eight to nine weeks after injury and again at one year. Our aim was to identify patients at risk for a delayed recovery and particularly those likely to develop complex regional pain syndrome. In order to quantify clinically the inflammatory response, a regional inflammatory score was developed. In addition, blood samples were collected from the antecubital veins of both arms for comparative biochemical and blood-gas analysis. The severity of the inflammatory response was related to the type of treatment (Kruskal-Wallis test, p = 0.002). A highly significantly-positive correlation was found between the regional inflammatory score and the length of time to full recovery (r2 = 0.92, p = 0.01, linear regession). A regional inflammatory score of 5 points with a sensitivity of 100% but a specificity of only 16% also identified patients at risk of complex regional pain syndrome. None of the biochemical parameters studied correlated with regional inflammatory score or predicted the development of complex regional pain syndrome. Our study suggests that patients with a distal radial fracture and a regional inflammatory score of 5 points or more at eight to nine weeks after injury should be considered for specific anti-inflammatory treatment.
We used an inverted shoulder arthroplasty in 43 consecutive patients with a mean age of 78 years (65 to 97) who had sustained a three- or four-part fracture of the upper humerus. All except two were reviewed with a mean follow-up of 22 months (6 to 58). The clinical outcome was satisfactory with a mean active anterior elevation of 97° (35° to 160°) and a mean active external rotation in abduction of 30° (0° to 80°). The mean Constant and the mean modified Constant scores were respectively 44 (16 to 69) and 66% (25% to 97%). Complications included three patients with reflex sympathetic dystrophy, five with neurological complications, most of which resolved, and one with an anterior dislocation. Radiography showed peri-prosthetic calcification in 36 patients (90%), displacement of the tuberosities in 19 (53%) and a scapular notch in ten (25%). Compared with conventional hemiarthroplasty, satisfactory mobility was obtained despite frequent migration of the tuberosities. However, long-term results are required before reverse shoulder arthroplasty can be recommended as a routine procedure in complex fractures of the upper humerus in the elderly.

The burden of non vertebral fractures on the National Health Service is enormous. Osteoporotic fractures have an associated morbidity and mortality and as a consequent incur heavy financial burden with a current cost to the National Health Service of some £1.7 billion per year, hip fractures accounting for the greater part. We know from our own local experience in the North of Ireland that this previous service had failed to target these fracture patients for secondary prevention of osteoporosis (Northern Ireland
