Shoulder replacement surgery is a well-established orthopaedic procedure designed to significantly enhance patients’ quality of life. However, the prevailing preoperative admission practices within our tertiary shoulder surgery unit involve a two-stage group and save testing process, necessitating an admission on the evening before surgery. This protocol may unnecessarily prolong hospital stays without yielding substantial clinical benefits.

The principal aim of our study is to assess the necessity of conducting two preoperative group and save blood tests and to evaluate the requirement for blood transfusions in shoulder arthroplasty surgeries. A secondary objective is to reduce hospital stay durations and the associated admission costs for patients undergoing shoulder arthroplasty. We conducted a retrospective observational study covering the period from 1st January 2023 to 31st August 2023, collecting data from shoulder arthroplasty procedures across three hospitals within the Aneurin Bevan University Health Board.

Our analysis included 21 total shoulder replacement cases and 13 reverse shoulder replacement cases. Notably, none of the patients required postoperative blood transfusions. The mean haemoglobin drop observed was 14 g/L for total shoulder replacements and 15 g/L for reverse shoulder replacements. The mean elective admission duration was 2.4 nights for total shoulder replacements and 2 nights for reverse shoulder replacements. Our data indicated that hospital stays were extended by one night primarily due to the preoperative group and save blood tests.

In light of these findings, we propose a more streamlined admission process for elective shoulder replacement surgery, eliminating the need for the evening-before-surgery group and save testing. Hospital admissions in these units incur a cost of approximately £500 per night, while the group and save blood tests cost around £30 each. This revised admission procedure is expected to optimise the use of healthcare resources and improve patient satisfaction without compromising clinical care.

ECSWT has been on the medical horizon for last 30 years mainly in urology for urolithiasis and has found a parallel use in orthopaedics for various chronic soft tissue conditions like Tendoachilles tendinoses and plantar fasciitis etc. ECSWT acts a piezoelectric device releasing acoustic energy and causing micro-trauma activating cytokine mediated response stimulating local angiogenesis and tissue repair.

Methodology

56 patients were recruited for the trial after ethics approval was achieved. The diagnosis was confirmed with ultrasound scan and measuring the width of the swelling and the local hypervascularity. The cohort of the patients was randomised in groups for physiotherapy [n=23] and shockwave therapy [n= 23]. The patient groups with shockwave therapy received a 3-week treatment with typical 2000 impulses per session once a week and physiotherapy group was subjected to eccentric loading exercises. Patients were assessed at 12 week with AOFAS, VISA-A scores and repeat ultrasound scan.

Results

The average age of the average age was 51 years [36- 73 years] Mean duration of symptoms prior to treatment was 25 months (range 6-60 months). AOFAS scores increased in both groups: from 64□86 in the ECSWT group and 72□79 in the physiotherapy group. VISA-A scores also increased in both groups from 39□73 in the ECSWT group and from 36□56 in the physiotherapy group. Scores were significantly higher in the ECWST group post treatment. The ultrasound scan findings suggested the tendon girth receding from 10.9 mm□9.9 mm in physiotherapy group while 9.8 mm□8.7 mm in the ECSWT group with hypervascularity decreasing from marked to mild in both groups. Statistical significance was established using SPSS 16 p < 0.001in post treatment group.

Introduction: Unstable inter-trochanteric fractures are increasing in incidence and stable fixation can improve outcome by leading to earlier mobilisation and reduced mortality. The appropriate choice of implant is vital to ensure a satisfactory outcome.

Objectives: The objective of this study was to determine the load at which different intramedullary device constructs failed.

Materials and Methods: Nine identical 3rd generation composite Sawbones were used and prepared with reverse obliquity cuts made to the femoral necks. Three different types of trochanteric entry intramedullary nail were then inserted using manufacturer’s guidelines. The nine constructs were loaded to failure using a Dartec 9500 servo hydraulic testing machine.

Results: The average failure loads were 3954±952N for the DePuy nail, 2420±281N for the Synthes nail and 3810±377N for the Stryker nail. In eight of the nine constructs the Sawbone failed at the medial side of the fracture. One of the DePuy nails failed at 5041N in the area of the distal locking screws.

The Stryker nail constructs were significantly stronger than the Synthes constructs (p=0.008); although the DePuy constructs were similar in strength to the Stryker constructs (p=0.83) they were not significantly different from the Synthes constructs (p=0.098).

Conclusion: There must be a balance between movement at the fracture site to allow compression but enough stability that the fracture may heal.

Our study showed that the Synthes nail failed at a significantly lower load than the DePuy or the Stryker nails. The Synthes construct failed at a typical walking load, around three times body weight for an 80kg patient.

We undertook a prospective randomised trial to determine the outcome of locked intramedullary fixation vs. plating of displaced shortened mid-shaft clavicle fractures. The primary outcome measure was the Constant shoulder score, while secondary outcome measures included the Oxford shoulder score, union rate, and complication rates.

Thirty-two patients were recruited to the trial; 17 randomised to locked intramedullary fixation and 15 randomised to plating. Mean age was 29.3years (13 to 53 years). Mean follow-up was 12.4 months (5 to 28 months). There was no significant difference in Constant scores (p = 0.365) and no significant difference in Oxford scores (p = 0.686). There was 100% union in both groups. In the intramedullary group, there was one case of soft tissue irritation that settled after the pin was removed, one pin backed out and had to be revised with another pin. There were three superficial wound infections resulting in plate removal and 8 plates (53%) were removed.

Locked intramedullary fixation and plating are equally effective in the management of shortened displaced mid-shaft clavicle fractures.

Background: The simultaneous occurrence of spina bifida occulta (SBO) and spondylolysis has been noted previously. The occurrence of SBO and spondylolysis are approximately 17% and 5% respectively.

Aims: The aim of this study was to determine the incidence of SBO when a symptomatic spondylolysis has been proven.

Method: Analysis of four years of lumbar spine CT scans was performed. Patients with spondylolysis or spondylolisthesis caused by a pars defect were identified. These patients’ CT images were then reviewed to establish the patients who also had SBO.

Results: In this unit 650 CT scans of lumbar spines were performed in the last five years. Of these scans 100 (15%) were found to have a pars defect. The average age was 34.6. On CT 30 (30%) patients were shown to have SBO. Of the total 23 were under 18 years old and 13 (56%) of these patients had SBO associated with the spondylolysis. In the over 18 year olds 21 (27%) patients had SBO associated with spondylolysis.

On review of the 550 other scans the average age was 51.9 years old. The incidence of SBO within this group is 10%. Only 6% of these patients were under 18. Out of these 33 patients 30.3% (10 patients) had SBO. Over 18 the incidence of SBO was only 8.5%.

Conclusions: Our results indicate that the occurrence of SBO within the group with a spondylolysis is much higher than in the group where no spondylolysis is present. There is higher incidence of SBO in the younger patients with spondylolysis. 56% of paediatric patients with symptomatic spondylolysis will have SBO. Clinicians should be aware of this fact preoperatively to decide on the technique of repair of the symptomatic lysis.

Introduction: Trochanteric bursitis is a common hip problem that can be refractory to treatment. The available modalities of treatment can be less effective. We evaluated the use of extra-corporeal shockwave therapy treatment for trochanteric bursitis.

Methodology: 22 patients with the clinical and radiological (in 6 patients) diagnosis of trochanteric bursitis were treated in a dedicated shockwave therapy clinic using Swiss dolocast radial shockwave therapy machine. 3 sessions of treatment were given one week apart, delivering 2000 impulses at 10 Hz at each session. Patients were evaluated prior to treatment, 3 months, 6 months and 12 months following their treatment. The visual analogue score (VAS) was used in all patients pre and post treatment. Hip disability and osteoarthritis score (HOOS) was performed post-treatment.

Results: Between December 2005 and November 2008 22 patients were treated for symptoms of trochanteric bursitis. There were 17 women and 5 men. The average age was 55.8 years (range 33–76 years). 6 patients had proven increase signal on MRI scan the rest were mainly clinical diagnosis and after a limited response to steroid injections. Their VAS improved from 10 to 5. Their post-treatment HOOS score averaged 255.

Of the 6 patients who had MRI proven increased signal 5 patients had significant improvement. The average improvement in the VAS was 10 to 2.3 and their HOOS scores were 349.2 (range 427–243).

Conclusion: Though the number of patients in this study is only 22 it seems that radial shockwave therapy treatment for trochanteric bursitis is promising, especially on those who have got high signal on MRI scans.
