Background Proximal humeral fractures, particularly in osteoporotic patients, remain an unsolved problem as regards the durability of the osteosynthesis. The AO/ASIF group has developed a new technique which aims to preserve the biological integrity of the humeral head and secures the reduction using multiple locking screws with angular stability (Philos), thus allowing an early mobilization.Patients and outcome We retrospectively reviewed the complications and functional outcome after a minimum follow-up of 1 year in 72 patients treated with this new method. 2 fractures failed to unite, and 3 patients developed an avascular necrosis of the humeral head. In addition, 2 implant failures were observed due to a technical error. According to the Constant score, the functional outcome was acceptable even in elderly patients.Interpretation The Philos method appears to be safe and can be recommended for the treatment of proximal humeral fractures in patients with poor bone quality.

We treated 108 patients with a pertrochanteric femoral fracture using either the dynamic hip screw or the proximal femoral nail in this prospective, randomised series. We compared walking ability before fracture, intra-operative variables and return to their residence. Patients treated with the proximal femoral nail (n = 42) had regained their pre-operative walking ability significantly (p = 0.04) more often by the four-month review than those treated with the dynamic hip screw (n = 41). Peri-operative or immediate post-operative measures of outcome did not differ between the groups, with the exception of operation time. The dynamic hip screw allowed a significantly greater compression of the fracture during the four-month follow-up, but consolidation of the fracture was comparable between the two groups. Two major losses of reduction were observed in each group, resulting in a total of four revision operations.Our results suggest that the use of the proximal femoral nail may allow a faster postoperative restoration of walking ability, when compared with the dynamic hip screw.The incidence of pertrochanteric femoral fractures has increased significantly during recent decades, and this tendency will probably continue in the near future due to the rising age of the population.

ObjectiveTo assess the efficacy of arthroscopic subacromial decompression (ASD) by comparing it with diagnostic arthroscopy, a placebo surgical intervention, and with a non-operative alternative, exercise therapy, in a more pragmatic setting.DesignMulticentre, three group, randomised, double blind, sham controlled trial.SettingOrthopaedic departments at three public hospitals in Finland.Participants210 patients with symptoms consistent with shoulder impingement syndrome, enrolled from 1 February 2005 with two year follow-up completed by 25 June 2015.InterventionsASD, diagnostic arthroscopy (placebo control), and exercise therapy.Main outcome measuresShoulder pain at rest and on arm activity (visual analogue scale (VAS) from 0 to 100, with 0 denoting no pain), at 24 months. The threshold for minimal clinically important difference was set at 15.ResultsIn the primary intention to treat analysis (ASD versus diagnostic arthroscopy), no clinically relevant between group differences were seen in the two primary outcomes at 24 months (mean change for ASD 36.0 at rest and 55.4 on activity; for diagnostic arthroscopy 31.4 at rest and 47.5 on activity). The observed mean difference between groups (ASD minus diagnostic arthroscopy) in pain VAS were −4.6 (95% confidence interval −11.3 to 2.1) points (P=0.18) at rest and −9.0 (−18.1 to 0.2) points (P=0.054) on arm activity. No between group differences were seen between the ASD and diagnostic arthroscopy groups in the secondary outcomes or adverse events. In the secondary comparison (ASD versus exercise therapy), statistically significant differences were found in favour of ASD in the two primary outcomes at 24 months in both VAS at rest (−7.5, −14.0 to −1.0, points; P=0.023) and VAS on arm activity (−12.0, −20.9 to −3.2, points; P=0.008), but the mean differences between groups did not exceed the pre-specified minimal clinically important difference. Of note, this ASD versus exercise therapy comparison is not only confounded by lack of blinding but also likely to be biased in favour of ASD owing to the selective removal of patients with likely poor outcome from the ASD group, without comparable exclusions from the exercise therapy group.ConclusionsIn this controlled trial involving patients with a shoulder impingement syndrome, arthroscopic subacromial decompression provided no benefit over diagnostic arthroscopy at 24 months.Trial registrationClinicaltrials.gov NCT00428870.

One year after a displaced midshaft clavicular fracture, nonoperative treatment resulted in a higher nonunion rate but similar function and disability compared with operative treatment.
