The objectives of our study were to compare patient reported outcome measures between manual and robotic-assisted total hip arthroplasty.

Between 1st May 2021 and 31st August 2022, 539 consecutive patients who underwent 564 primary total hip arthroplasties were identified from the local registry database. Data were prospectively collected, and included patient demographics, American Society of Anaesthesiologists (ASA) grade, surgical approach, robotic-assistance, Oxford Hip Score (OHS), EQ-5D-3L and EQ-VAS pre-operatively and at twelve months.

Robotic-assistance, compared against manual total hip arthroplasty, was associated with an enhanced median (interquartile range) OHS (46 [42 – 48] vs 43 [36 – 47], p-value < 0.001), EQ-5D-3L (5 [5 – 7] vs 6 [5 – 8], p-value 0.002), and EQVAS (90 [75 – 95] vs 80 [70 – 90], p-value 0.003) at twelve months after surgery. Robotic-assistance was confirmed to be an independent predictor of a greater OHS at twelve months on a multivariate linear regression analysis (p-value 0.001).

Robotic assistance was superior to manual total hip arthroplasty in enhancing patient reported outcomes at twelve months after surgery.

Our unit historically performed total hip replacement (THR) through either posterior or anterolateral approaches. In November 2020 a group of 5 consultants transitioned to utilising the Direct Anterior Approach (DAA). Appropriate training was undertaken and cases were performed as dual consultant procedures with intraoperative radiography or robotic assistance.

Outcomes were collated prospectively. These included basic demographics, intraoperative details, complication rates and Oxford Hip Scores.

A total of 48 patients underwent DAA THR over 1 year. Mean age was 67 and ASA 2. Over this time period 140 posterior approach and 137 anterolateral approach THR's were performed with available data. Propensity score matching was performed on a 1:1 basis using BMI, Age, Sex and ASA as covariates to generate a matched cohort group of conventional approach THR (n=37)

Length of stay was significantly reduced at 1.95 days (p<0.001) with DAA compared to Anterolateral and Posterior approach. There was no significant difference with length of surgery, blood loss, Infection, dislocation and periprosthetic fracture rate. There was no significant difference in Oxford Hip Score between any approach at 3 months or 1 year.

The transition to this approach has not made a negative impact despite its associated steep learning curve, and has improved efficiency in elective surgery. From our experience we would suggest those changing to this approach receive appropriate training in a high-volume centre, and perform cases as dual consultant procedures.

The best surgical treatment of lateral epicondylitis remains uncertain. Recently radiofrequency microtenotomy (RFMT) has been proposed as a suitable surgical treatment. We aim to compare open release with RFMT and present the results of our randomised controlled trial.

Patients with symptoms of tennis elbow for at least 6 months who had failed to respond to conservative management were included in the trial. They were randomised to open release or RFMT. Outcome measures included grip strength, pain and DASH scores.

41 patients were randomised, 23 to RFMT and 18 to open release, 2 patients withdrew from the study. Our results show that both treatments give a significant benefit at all time points for DASH and pain scores, but only open release gives a significant improvement in grip strength. Comparing the two treatments the only significant difference is the open group have better pain scores at 6 weeks, but this is not seen at later follow up.

In conclusion both groups have shown benefit from the treatments, but one is not shown to be clearly superior.

The upper age limit for Paediatric Orthopaedic referrals and admissions has recently been increased from 14 to 16 years. This has many benefits but will change the volume of cases as well as influencing both case mix and the resources required. We analysed the operations and admissions in our department for the year preceding and succeeding the change in age limit in order to evaluate the impact on the service. Our outcome measures were number of trauma and elective cases treated, time spent operating, case mix and cost to the service.

Admission and operative logs for the aforementioned years were analysed to obtain number of admissions, length of stay and operative intervention as well as time in theatre. National reference data from Information Services Division Scotland was used in order to get accurate costs for theatre time and inpatient stays in our hospital.

Results showed an increase in total number of cases from 438 per year to 499. Trauma cases increased from 133 (30.4%) to 202 (40.5%). Of these, 35 (17.3%) were over 14 years. The number of children over 14 years which had an operation, doubled from 51 to 102. Hours spent operating increased from 681.25 to 830.25. The percentage time operating on those aged over 14 increased from 13.2% to 23.8%. Theatre costs increased by £148005 (21.9%) to £822442.50.

The change in age limit has significantly increased case variety and numbers. This has significant financial implications and as such needs adequately resourced to ensure high quality clinical care.

This prospective Randomised Controlled Trial compared two surgical approaches with respect to accuracy of guidewire and tibial nail position.

Sixty-seven patients with tibial fractures were randomised to semi-extended (SE) or standard (S) approaches of nail insertion. Fluoroscopy was performed at guidewire insertion and final nail position. The SE approach is more proximal with the guidewire inserted posterior to the patella, theoretically allowing a better angle for more accurate nail placement.

Measurements were taken in the Anteroposterior and lateral planes of both the nail and guidewire to determine deviation from the optimal angle of insertion (relative to the long axes of the tibial shaft). Thirty-nine and twenty-eight patients were treated with semiextended and standard approaches respectively.

The semiextended approach resulted in improved nail placement to statistical significance in both planes, with mean deviation from the optimal angle of insertion as below:

Guidewire AP 3.2° (SE) versus 4° (S) Lateral 27.1° (SE) versus 30.2° (S)

Nail AP 2.4° (SE) versus 4.2° (S) Lateral 17.9° (SE) versus 21.8° (S)

Poor positioning of the guidewire leads to excessive anterior placement of the nail by eccentric reaming. Anterior positioning of the guidewire and nail in the lateral plane was assessed. This was expressed as a percentage from the anterior cortex of the tibia.

Guidewire: Lateral 9.7% (SE) versus 9.3% (S)

Nail: Lateral 23.4% (SE) 19.3% (S) (p 0.043)

Semiextended nailing allows a better angle for guidewire placement and a more optimal final nail position. This facilitates accurate nail placement particularly in difficult proximal third fractures.

Frozen shoulder is a common condition that affects the working population. The longevity and severity of symptoms often results in great economic burden to health services and absence from work. This prospective cohort study aimed to investigate whether early intervention with arthroscopic capsular release resulted in improvement of symptoms and any potential economic benefit to society.

Patients were recruited prospectively. Data was gathered by way of questionnaire to ascertain demographics, previous primary care treatment and absence from work. Oxford Shoulder Score (OSS) was also calculated. Arthroscopic capsular release was performed and further data gathered at four week post-operative follow up. Economic impact of delay to treatment and cost of intervention was calculated using government data from the national tariff which costs different forms of treatment. Statistical analysis was then performed on the results.

Twenty five patients enrolled. Mean pre-operative OSS: 37.4 (range 27–58, SD 7.4). Mean post-operative OSS: 15.9 (range 12–22, SD 2.3). P<0.01. Mean improvement in OSS: 21.5 (range 12–38, SD 7.1)

The cost of non-operative treatment per patient was £3954. The cost of arthroscopic capsular release per patient was £1861, a difference of £2093. There were no complications

Arthroscopic capsular release improved shoulder function on OSS within four weeks. The cost of arthroscopic capsular release is significantly less than the cost of treating the patients non-operatively. Early surgical intervention may improve symptoms quickly and reduce economic burden of the disease. A randomised controlled trial comparing timings of intervention would further elucidate potential benefits.

This ongoing prospective RCT compares two surgical approaches with respect to accuracy of guidewire and tibial nail position.

29 patients with tibial fractures were randomised to semi-extended (SE) or standard (S) approaches of tibial nail insertion. Fluoroscopy obtained guidewire and final nail position. The SE approach is more proximal with the guidewire inserted posterior to the patella, theoretically allowing more accurate wire and nail placement.

Measurements were taken in both planes of the nail and guidewire to determine deviation from optimum angle of insertion (relative to the long axes of the tibial shaft).

14 and 15 patients were treated with semi-extended and standard approaches respectively.

The semi-extended approach results in better guidewire and nail placement in both planes with mean deviation from the optimal angle of insertion as below:

Guidewire AP 4.5° (SE) versus 4.04° (S) Lateral 24.59° (SE) versus 33.36° (S)

Nail AP 3.21° (SE) versus 3.68° (S) Lateral 17.73° (SE) versus 24.04° (S)

Anterior knee pain may be due to excessive anterior placement of the nail. We assessed anterior placement of the guidewire and nail in the lateral plane. This was expressed as a percentage from the anterior cortex of the tibia. Mean results are below:

Guidewire 9.7% (SE) versus 9.3% (S)

Nail 19.5% (SE) versus 16.3% (S)

Semi-extended nailing may allow for better guidewire position and as such nail placement. This may reduce anterior knee pain.

ARI is a busy trauma unit (catchment: 500 000 people). In September 2010 a day-case Hand Trauma Service (HTS) started. Previously cases were often postponed due to prioritisation of orthopaedic emergencies; therefore increasing inpatient stay and associated costs. We aim to characterise presenting cases, evaluate improvements in service provision and financial costs.

Data was collected from the first HTS year (Sept 10–11), and the preceding year (Sept 09–10). Data was collected on patient characteristics, operation, operative time, anaesthetic type and number of inpatient days. The cost of inpatient stay was calculated from the NHS Scotland resource allocation committee data.

Pre HTS there were 410 cases (500 operative hours). 141 wound explorations, 22 nail-bed repairs, 34 metacarpal ORIF, 68 phalangeal ORIF, 5 scaphoid fixations, 69 tendon repairs, 30 terminalisations, 5 MUA, 19 nerve repairs, 17 unclassified. Accounting for 510 inpatient nights (mean: 1.25, range: 0–8), costing £204,387.60 (mean: £500.95). 123 cases required image intensification (II). Most patients had GA. During the first HTS year there were 282 operations. Most operations were day-case. 77 cases were performed under LA, 81 regional blocks and 34 under GA. During this year cases requiring II continued to be performed in the main theatre.

The HTS has increased time available in main theatres. It has reduced inpatient stay costs, potentially saving £141,267.90. Performing more operations under LA/regional block decreases the risks associated with anaesthesia. Provision of II for the HTS would permit more cases to be performed, improving the service provision and further reducing costs.
