This prospective, randomized, controlled trial compares patient outcome after non-operative care versus open reduction and tunneled suspension device fixation (ORTSD) for grade III or IV acromioclavicular joint disruptions.

Sixty patients aged between sixteen and thirty-five years with an acute grade III or IV AC joint disruption were randomized to receive ORTSD fixation or non-operative treatment. Functional assessment was conducted at six weeks, three months, six months, and one year using the Disabilities of the Arm, Shoulder and Hands (DASH), Oxford Shoulder Scores (OSS) and Short Form (SF-12). Reduction was evaluated using radiographs. Complications were recorded, and an economic evaluation performed.

There was no significant difference in DASH or OSS at one year between non-operative and ORTSD groups (DASH score, 4.67 versus 5.63; OSS, 45.72 versus 45.63). Patients undergoing surgery had inferior DASH scores at 6 weeks (p<0.01). Five patients who failed non-operative management subsequently received surgery. Overall cost of treatment was significantly greater after ORTSD fixation (£796.22 vs £3359.73 (p<0.01)).

ORTSD fixation confers no functional benefit over non-operative treatment at one year. While patients managed non-operatively generally recover faster, a significant group remain dissatisfied following non-operative treatment requiring delayed surgical reconstruction.

Aims

The primary aim of this study was to establish the cost-effectiveness of the early fixation of displaced midshaft clavicle fractures.

The primary aim of this study was to undertake a cost-effectiveness analysis (CEA) of acute fixation versus conservative management of displaced midshaft clavicle fractures. The secondary aim was to conduct a sensitivity analysis of patient characteristics that may influence a threshold of £20,000 per quality-adjusted life year gained (QALY).

A CEA was conducted from a randomised control trial comparing conservative management (n=92) to acute plate fixation (n=86) of displaced midshaft clavicle fractures. The incremental cost effectiveness ratio (ICER) was used to express the cost per QALY. The short form 6-dimensional (SF-6D) score was the preference based index to calculate the cost per QALY.

The 12-month SF-6D advantage of acute fixation over conservative management was 0.0085 (p=0.464) with a mean cost difference of £4,096.22 and resultant ICER of £481,908.24/QALY. For a threshold of £20,000/QALY the benefit of acute fixation would need to be present for 24.1 years. Linear regression analysis identified nonunion as the only independent factor to influence the SF-6D at 12-months (p<0.001). Conservatively managed fractures that resulted in a nonunion (n=16) had a significantly worse SF-6D compared to acute fixation (0.0723, p=0.001) with comparable healthcare cost at 12-months (£170.12 difference). Modelling the ICER of acute fixation against those complicated by a nonunion proved to be cost effective at £2,352.97/QALY at 12-months.

Routine plate fixation of displaced midshaft clavicle fractures is not cost-effective. Patients with nonunion after conservative management have increased morbidity with comparable expense to those undergoing acute fixation which suggests targeting these patients is a more cost-effective strategy.

The optimal approach for total hip arthroplasty (THA) remains controversial. We present the results of the Direct Superior Approach (DSA), an improved variation of the posterior approach with high levels of stability, patient-reported functional outcomes, and satisfaction.

This is a single-surgeon prospective series. All patients undergoing THA between 2010 and 2015 via the DSA were included. Complication data was collected by interrogation of the Scottish Arthroplasty Project national joint registry. Pre and one-year post-operative Oxford Hip Score (OHS), Euroqol-5D (EQ-5D), and patient satisfaction questionnaires were collected.

659 patients received a THA via the DSA during the study period. Average age was 61.8 years (range 16.4–93.3). Analysis of registry data revealed no cases of dislocation, 5 cases of venous thromboembolism (0.75%), and 5 cases of deep infection (0.75%). 586 patients (88.9%) underwent their surgery in the National Health Service, and post-operative outcomes were available for 337 of these patients (57.5% follow-up) at one year. Average improvement in OHS and EQ-5D was 20 (range −14 – 48) and 0.39 (−0.697–1.2) respectively. 311 patients (92.3%) were satisfied.

This description of the DSA is accessible to all surgeons, confers excellent stability with no dislocations, and is associated with excellent post-operative functional outcomes and patient satisfaction.

This study aimed to evaluate the effect of clavicular shortening, measured by three-dimensional computerized tomography (3DCT), on functional outcomes and satisfaction in patients with healed, displaced, midshaft clavicle fractures up to one year following injury.

The data used in this study were collected as part of a multicenter, prospective randomized control trial comparing open reduction and plate fixation with nonoperative treatment for displaced midshaft clavicle factures. Patients who were randomized to nonoperative treatment and who had healed by one year were included. Clavicle shortening relative to the uninjured contralateral clavicle was measured on 3DCT. Outcome analysis was conducted at six weeks, three months, six months and one year following injury and included the Disabilities of the Arm, Shoulder and Hand (DASH), Constant and Short Form-12 (SF-12) scores, and patient satisfaction.

48 patients were included. The mean shortening of injured clavicles, relative to the contralateral side, was 11mm (+/− 7.6mm) with a mean proportional shortening of 8percnt;. Proportional shortening did not significantly correlate with the DASH (p>0.42), Constant (p>0.32) or SF-12 (p>0.08) scores at any time point. There was no significant difference in the mean DASH or Constant scores at any followup time point both when the cut off for shortening was defined as one centimeter (p>0.11) or two centimeters (p>0.35). There was no significant difference in clavicle shortening between satisfied and unsatisfied patients (p>0.49).

This study demonstrated no association between shortening and functional outcome or satisfaction in patients with healed, displaced, midshaft clavicle fractures up to one year following injury.
