Safety of early weightbearing after ankle fracture fixation.

PURPOSE: Patients with surgically treated ankle fractures are traditionally kept non-weightbearing for at least six weeks post-operatively; however, recent literature suggests numerous benefits of early weightbearing (EWB) before six weeks without significantly impacting long-term outcomes. This study aims to review the safety of early vs late weightbearing following ankle fracture fixation by assessing the complication rate. METHODS: This was a single-centre retrospective study. Between 2020 and 2023, all ankle fixations that commenced weightbearing at two weeks were added to the EWB group. An equal number of similar patients with six-week non-weightbearing were added to the late weightbearing (LWB) group. Baseline characteristics, risk factors, types of fractures and any complications in the six-month post-operative period were evaluated from these cohorts. RESULTS: In total, 459 ankle fixations were identified of which 87 patients met the criteria for the EWB group, with a further 87 added to the LWB group. There was no significant difference in age between the two groups (51.7 ± 20.1 vs 51.0 ± 15.5, respectively; p = 0.81), but more female patients and diabetics in the EWB group. Fracture types were similar between both cohorts (p = 0.51). Complication rate in the EWB group was not significantly different to the LWB group (5 vs 9, p > 0.05). CONCLUSION: No increase in complication rate was identified by commencing weightbearing early at two weeks after ankle fixation compared to six weeks. We therefore suggest EWB if appropriate, given its associated benefits including restoration of patient independence and improved quality of life. LEVEL OF EVIDENCE: Therapeutic, Level IV.

Fashioning autologous bone graft from the fibula in the transfibular approach to open ankle arthrodesis.

Open ankle arthrodesis is one of the primary operations for disabling ankle arthrosis. The transfibular lateral approach to ankle fusion is a common approach for open ankle arthrodesis. Autologous bone graft can be harvested from the osteotomised fibula. We describe a safe technique of taking graduated slices of fibula bone graft, which allows optimal fibula length excision and are suitable in shape to pack into defects at the fusion site.

Gastrocnemius Release in the Treatment of Achilles Tendinopathy: A Systematic Review.

Background: The aim of this study is to evaluate the use of isolated gastrocnemius release in the treatment of Achilles tendinopathy. The primary outcome is the change in patient-reported pain outcomes. Secondary outcomes include the change in patient-reported foot and ankle function, ankle range of motion and strength, patient satisfaction and rate of surgical complications. Methods: A systematic review was undertaken of studies involving patients treated with an isolated gastrocnemius release for Achilles tendinopathy. Randomised controlled trials, cohort studies, case-control studies and case series were eligible and identified from the following databases: MEDLINE and EMBASE. Results: Isolated gastrocnemius release results in improved patient-reported outcome scores for pain and foot and ankle function. There is an increase in ankle range of motion but a reduction in ankle strength. Patients report a high rate of overall satisfaction. The most common surgical complications are sural nerve injury and wound infection. Conclusions: Isolated gastrocnemius release may offer maintained and clinically meaningful improvements in pain and foot and ankle function with an associated reduction in ankle strength.

Ultrasound scanning for recalcitrant plantar fasciopathy. Basis of a new classification.

OBJECTIVE: The treatment of recalcitrant plantar fasciopathy is often empirical. Imaging is usually in the form of radiographs, if undertaken at all. The aim of this study is to characterise the disease pattern in recalcitrant cases of plantar fasciopathy. This allows classification of the pathology, which in turn allows meaningful evaluation of current and future treatments. MATERIALS AND METHODS: One hundred and twenty-five consecutive feet with symptoms of 'plantar fasciitis' lasting longer than 6 months (all of which had failed to improve with a stepwise conservative management protocol) had confirmed plantar fasciopathy on ultrasound scanning. The disease characteristics were evaluated based on the scan findings. RESULTS: Of the patients evaluated, 66 % had typical insertional disease. The remaining 34 % had atypical distal fascia disease; 22 % had mixed insertional and distal disease, and 12 % had pure distal disease. Patients with pure distal disease were found to have either distal thickening or discrete fibromata. CONCLUSION: In this cohort of recalcitrant cases, ultrasound scans detected a high proportion of atypical non-insertional plantar fascia disease. This would not be detected without imaging studies, and therefore we recommend the use of ultrasound scanning in cases of recalcitrant plantar heel pain that have failed proper first-line management, in order to confirm the clinical diagnosis and to classify the disease as either insertional or non-insertional plantar fasciopathy (or mixed disease). Only in this way can treatments for this group of patients be systematically evaluated against different disease patterns to determine their effectiveness.

Extracorporeal shock wave treatment in foot and ankle fracture non-unions - A review.

BACKGROUND: The authors reviewed the current evidence and conducted a comprehensive review on the use of extracorporeal shock wave therapy (ESWT) in the treatment of foot and ankle fracture non-unions. METHODS: Four databases were searched to identify relevant studies in the available literature. RESULTS: Eight studies were reviewed, demonstrating union rates of 65%-100% and 90-100% at 3- and 6-months following ESWT treatment respectively. No major complications were seen in any of the studies. Minor complications included local soft tissue swelling, petechiae, bruising and pain. CONCLUSIONS: The literature that is currently available is limited to case series of relatively small sample sizes, highlighting the need for a prospective randomised controlled trial to further investigate the efficacy of ESWT in the treatment of foot and ankle fracture non-unions.

Use of Fat-Suppressed T2-Weighted MRI Images to Reduce the Magic Angle Effect in Peroneal Tendons.

INTRODUCTION: Peroneal tendon disorders pose a diagnostic conundrum to the clinician. Magnetic resonance imaging (MRI) is widely used to assess tendon pathology. A recognized artifact of MRI, the magic angle effect (MAE), can lead to spurious results and inappropriate management. The aim of this study is to assess whether T2 fat-suppressed sequences (T2FSs) reduce the frequency of MAE compared with proton density fat-suppressed (PDFS) images. METHODS: MRI scans of 18 patients were prospectively assessed for MAE. The peroneal tendons were assessed at 5 defined levels on PDFS and T2FS images. The frequency of MAE in the peroneal tendons were compared between the 2 scan sequences. RESULTS: In the peroneus brevis tendon, 17/72 levels, on PDFS scans, showed MAE compared with 2/72 levels on the T2FS scans, demonstrating a reduction in the MAE by 85% (P = .0003). In the peroneus longus tendon 14/72 levels, on PDFS scans, demonstrated MAE compared with 4/72 on T2FSs, demonstrating a reduction of 71% (P = .02). CONCLUSION: The inclusion of T2-weighted sequences is useful in MRI scanning for peroneal tendons to mitigate the MAE artifact, avoid potential misdiagnosis, and guide subsequent management of peroneal tendon disorders. Levels of Evidence: Level IV: Case series.

Xenon and sevoflurane protect against brain injury in a neonatal asphyxia model.

BACKGROUND: Perinatal hypoxia-ischemia causes significant morbidity and mortality. Xenon and sevoflurane may be used as inhalational analgesics for labor. Therefore, the authors investigated the potential application of these agents independently and in combination to attenuate perinatal injury. METHODS: Oxygen-glucose deprivation injury was induced in pure neuronal or neuronal-glial cocultures 24 h after preconditioning with xenon and/or sevoflurane. Cell death was assessed by lactate dehydrogenase release or staining with annexin V-propidium iodide. The mediating role of phosphoinositide-3-kinase signaling in putative protection was assessed using wortmannin, its cognate antagonist. In separate in vivo experiments, perinatal asphyxia was induced 4 hours after preconditioning with analgesic doses alone and in combination; infarct size was assessed 7 days later, and neuromotor function was evaluated at 30 days in separate cohorts. The role of phosphorylated cyclic adenosine monophosphate response element binding protein in the preconditioning was assessed by immunoblotting. RESULTS: Both anesthetics preconditioned against oxygen-glucose deprivation in vitro alone and in combination. The combination increased cellular viability via phosphoinositide-3- kinase signaling. In in vivo studies, xenon (75%) and sevoflurane (1.5%) alone as well as in combination (20% xenon and 0.75% sevoflurane) reduced infarct size in a model of neonatal asphyxia. Preconditioning with xenon and the combination of xenon and sevoflurane resulted in long-term functional neuroprotection associated with enhanced phosphorylated cyclic adenosine monophosphate response element binding protein signaling. CONCLUSIONS: Preconditioning with xenon and sevoflurane provided long-lasting neuroprotection in a perinatal hypoxic-ischemic model and may represent a viable method to preempt neuronal injury after an unpredictable asphyxial event in the perinatal period.

Improving Documentation and Communication Using Operative Note Proformas.

Accurate and detailed documentation of surgical procedures is part of good clinical practice, set out by the General Medical Council (GMC). Knee arthroscopy often involves large data sets which require accurate documentation for future assessment and management. This study assesses the quality of documentation of knee arthroscopy, followed by an evaluation of the implementation of a novel operative proforma. A review of 30 consecutive knee arthroscopy operation notes were analysed for missing information, set against a standardised 30 point criteria. An operation proforma was then introduced, and a further 30 consecutive knee arthroscopy operation notes were analysed. We evaluated allied health professional satisfaction with a Likert point scale survey of 21 allied healthcare professionals (recovery and ward nurses, and physiotherapists) following introduction of the proforma. The mean number of missing items on a 30 point scale was 8.8 (range 0 to 23). Examination under anaesthesia was missed in 43% of cases, tourniquet time in 37% of cases, and wear results in 17% of cases. Following introduction of the proforma, the mean number of missing items was 1.1 (range 0 to 24; p <0.001). This rose to 3.8 after one year (p <0.001) before improvement to 0.7 (p <0.01) with a new and improved proforma. Eighty percent strongly agreed the operation note was clearer, 90% strongly agreed it was more legible, 90% strongly agreed it was more understandable, 50% strongly agreed there was more information recorded, and 100% strongly agreed on the proforma having been improved. Knee arthroscopy is a common procedure with large data sets, which can often be missed or incomplete. A standardised proforma results in a statistically significant improvement in documentation and reduces the incidence of missing information. They are subjectively clearer, more legible, and generally better compared with handwritten notes. This study demonstrates the improvements in healthcare documentation, both clinically and legally, following introduction of a simple proforma. This concept should be applicable to different specialities and procedures in healthcare.

Lateral Clavicle Fracture Fixation Using a Superiorly Placed Locking Plate.

Clavicle fractures are common injuries that account for 4% of all fractures, and approximately 21% of clavicle fractures are lateral. Studies have demonstrated that displaced lateral clavicle fractures with disruption of the coracoclavicular ligaments have nonunion rates as high as 28%. Many surgical techniques for fixation of lateral-end clavicle fractures have been proposed. More recently, locking plate technology has led to the development of superiorly placed locking plates, which are used when the distal fragment is large enough and which offer greater biomechanical stability in osteoporotic or metaphyseal bone. Our surgical technique for use of a compression plate for an unstable and displaced lateral clavicle fracture consists of the following steps. Step 1: identification of the fracture pattern and surgical planning. Step 2: setup of the operating room with the image intensifier in an optimum position for satisfactory intraoperative images. Step 3: approach, through a bra-strap incision centered over the fracture. Step 4: reduction of the fracture and temporary stabilization. Step 5: implant selection based on sizing and patient anatomy. Step 6: application of the plate of choice and fixation with a combination of proximal bicortical screws and distal locking screws. Step 7: closure in layers and application of postoperative slings and dressings. Patients follow a graduated physiotherapy regimen postoperatively. Studies have demonstrated high union rates following lateral clavicle fracture fixation with good-to-excellent functional outcomes and a combined complication rate of approximately 6%.

Gait Analysis From a Single Ear-Worn Sensor: Reliability and Clinical Evaluation for Orthopaedic Patients.

Objective assessment of detailed gait patterns after orthopaedic surgery is important for post-surgical follow-up and rehabilitation. The purpose of this paper is to assess the use of a single ear-worn sensor for clinical gait analysis. A reliability measure is devised for indicating the confidence level of the estimated gait events, allowing it to be used in free-walking environments and for facilitating clinical assessment of orthopaedic patients after surgery. Patient groups prior to or following anterior cruciate ligament (ACL) reconstruction and knee replacement were recruited to assess the proposed method. The ability of the sensor for detailed longitudinal analysis is demonstrated with a group of patients after lower limb reconstruction by considering parameters such as temporal and force-related gait asymmetry derived from gait events. The results suggest that the ear-worn sensor can be used for objective gait assessments of orthopaedic patients without the requirement and expense of an elaborate laboratory setup for gait analysis. It significantly simplifies the monitoring protocol and opens the possibilities for home-based remote patient assessment.

The incidence and natural history of forefoot scar pain following open hallux valgus surgery.

BACKGROUND: Scar symptoms are a recognized complication of forefoot surgery. The aim of our study was to quantify and qualify these symptoms following open Scarf osteotomy for hallux valgus. METHODS: A total of 125 consecutive patients with a minimum of 1 year's follow-up were questioned, with a response rate of 82%. Four patients were excluded because of superficial wound infections, leaving 98 patients in the study. RESULTS: In all, 30 patients (31%) reported scar symptoms. In this symptomatic group, 8 patients (21%) undertook noninvasive intervention for their symptoms, and the remaining 22 symptomatic patients (79%) did not use any form of intervention for their symptoms. Patients who undertook some sort of intervention had a significantly shorter duration of symptoms (mean = 19 vs 44 weeks; P = .01). The mean duration of symptoms was 27.9 weeks, and mean symptom score was 3 out of 10. At the 1-year follow-up, 95% of patients had no scar symptoms. There was no significant difference in either the preoperative severity of the deformity or the degree of correction achieved between the symptomatic and asymptomatic patients. CONCLUSION: These results can be used to obtain consent, educate, and reassure patients. We recommend simple noninvasive interventions should patients experience postoperative scar symptoms.
