We report the functional outcome and survivorship of the Hintegra Total Ankle Replacement (TAR), in consecutive cases by multiple surgeons in a single UK institution. Between 2010–2014 the Hintegra TAR held 7.1% UK market share and surgeons should be aware of failure mechanisms. We conducted a retrospective review of prospectively collected data for 70 consecutive Hintegra TAR cases in a single institution between 2010–2014. Data collected included patient demographics, complications, reoperations, patient reported outcome measures (PROMS: AOS, MOX-FQ, pain VAS) and patient satisfaction.Introduction
Methods
When ankle arthroplasty fails the options are revision to arthrodesis or revision to arthroplasty. We report early outcomes of revision procedures for failed total replacement. Retrospective review of prospectively collected data including post-operative complications, union, survivorship and PROMS scores to compare revision to arthrodesis and revision to arthroplasty.Introduction
Methods
Lateral approach open calcaneal osteotomy is the described gold standard procedure in the management of hindfoot deformity. With development of minimally invasive surgery, a MIS approach has been described, citing fewer wound complications and lower risk of sural nerve injury. This audit compares MIS to the traditional procedure. A retrospective review of all patients undergoing calcaneal osteotomy in Northumbria Trust in the past 5 years was performed. A total of 105 osteotomies were performed in 97 patients; 28 (13M:15F) in MIS group and 77 (40M:37F) had an open approach. The average age was 52.1 (range 16–83) for MIS and 51.5 (range 18–83) in the open group. All patients were followed up for development of wound complication, nerve injury and fusion rate. Wound complications were similar (10.7% in MIS group vs 10.3% in Open group) with no significant difference (p=0.48). Patients were treated for infection in 3(3.8%) cases in the open group and 2(7.1%) in the MIS group. This difference was not significant (p=0.43). 4 (14.3%) patients in the MIS group had evidence of sural nerve dysfunction post-operatively (managed expectantly), compared to 12(15.5%) patients in the open group (p=0.44). Of these, 2 went on to undergo neuroma exploration. There was no difference in nerve dysfunction in varus or valgus correction. Mean translation in the open group was measured as 7.3mm(SD=1.91;3 to 13mm) and 7.5mm(SD=1.25;5 to 10mm) in the MIS group. Translation was similar in varus or valgus correction. Non-union occurred in 2 patients in the MIS group and none in the open group (p= 0.06). MIS calcaneal osteotomy is a safe technique, that works as effectively as osteotomy performed through an open approach. There were lower rates of nerve injury, wound complication and infection, but this was not significantly different comparing groups. There was a higher risk of non-union in MIS technique.
Day Case Surgery (defined as same day discharge) is a priority within the National Health Service and has been shown to provide beneficial outcomes for patients and hospitals. We report our experience developing a Day Case Programme for Total Ankle Replacement (TAR). Prior to the introduction of a Day Case Programme, average length of stay following TAR in our unit was 3.5 days. Stakeholders were consulted about ways in which same day discharge could be facilitated. Patients' post-operative pain charts were reviewed prior to the introduction of this programme. Inclusion criteria included non-complex surgery (anticipated tourniquet < 2hrs), friend or relative support and pre-operative walking-aid assessment. An enhanced recovery protocol included long-acting popliteal block and dexamethasone. Patients were discharged with opiate analgesia and written pain instructions. Patients were asked to complete a pain and satisfaction questionnaire. Patient Reported Outcome Measures (PROMs) were recorded.Introduction
Methods
The use of a knotless TightRope for the stabilisation of a syndesmotic injury is a well-recognised mode of fixation. It has been described that the device can be inserted using a “closed” technique. This presents a risk of saphenous nerve entrapment and post-operative pain. We aimed to establish the actual risk of injury to the Saphenous Nerve using a “closed” technique for the insertion of a TightRope.Background
Aim
Traditionally, the extended lateral approach (ELA) was the favoured approch for calcaneal fractures, but has been reported to have high incidence of wound complications. There has been a move amongst surgeons in the United Kingdom towards the sinus tarsi approach (STA) due to its minimally invasive nature, attempting to reduce such complications. To evaluate outcomes of ELA and STA for all consecutive calcaneal fracture fixation in our institution over a 10yr period.Background
Aims
Platelet rich plasma has been advocated for the treatment of plantar fasciitis but there are few good quality clinical trials to support its use. We report a pilot double blind randomised controlled trial of platelet rich plasma versus normal saline. Patients with more than 6 months of MRI proven plantar fasciitis who had failed conservative management were invited to participate in this study. Patients were block randomised to either platelet rich plasma injection (intervention) or equivalent volume of normal saline (control). The techniques used for the injection and rehabilitation were standardised for both groups. The patient and independent assessor were blinded. Visual analogue scale for pain (VAS) and painDETECT were recorded pre-op and at 6 months. Twenty-eight patients (19 females, mean age 50 years) were recruited, with 14 randomised to each arm. At 6 month follow-up, 8 patients (28.6%) were lost to follow-up. There was a significant change in VAS score from baseline to follow-up in both intervention (mean change 37.2, p = 0.008) and control (mean change 42.2, p = 0.003) groups. However there was no difference between the arms in terms of the change in VAS score from baseline to follow-up (p = 0.183). There was no correlation between pre-op PainDETECT score and change in VAS.Methods
Results
Single photon emission computed tomography (SPECT) can be used to create a three dimensional image of a radiopharmaceutical bone scan. This combined with high resolution CT scan (SPECT-CT) with bone windows allows the linking of the information obtained in both investigations. The multiplanar anatomical information provided by CT is therefore linked with the functional, biological information of bone A retrospective analysis of all patients having SPECT-CT for continuing pain following TAR. Scans were requested in addition to plain radiographs, joint aspiration and blood testing. Results: A total of 12 patients were identified. The scan proved helpful in all cases. 5 patients showed increased uptake around one or both prostheses signifying loosening which was not apparent on plain films. Gutter impingement was identified in 4 patients. One patient had a talo-navicular non-union, one patient demonstrated sub-talar joint Introduction
Materials and Methods
Ankle We report a prospective comparative clinical study comparing open and arthroscopic ankle arthrodesis at two institutions with two-year follow-up. The primary outcome was the Ankle Osteoarthritis Scale and secondary outcomes included the SF-36, hospital stay and radiographic alignment. A power calculation was performed. There were 30 patients in each group.Background
Methods
The aim of this study was to determine the outcome of carpal tunnel decompression in elderly patients and whether this can be predicted by the severity of pre-operative nerve conduction studies. A retrospective study was undertaken of all patients over 70 years who had carpal tunnel release (CTR) at Dunedin Hospital between April 1999 and April 2002 with a minimum one year follow up. A grading system for pre-operative nerve conduction studies (NCS) was formulated which scored patients from 1 to 6 according to severity. Patients were followed up by postal questionnaire (Boston Carpal Tunnel Score) with telephone follow up of non-responders. There were 105 CTR procedures performed in 96 patients. Median pre-operative NCS Score was 4 with 47% scoring 5 or 6. 4 Patients had died. Post-operative symptom severity scores were low and the majority of patients were very satisfied with the results of surgery. Despite nerve conduction studies consistent with severe median nerve compression, patients had low postoperative symptom severity scores and overall were very satisfied. Carpal tunnel release in patients over 70 years of age is justified and associated with good outcome.
