Background. 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. Aim. We aimed to establish the actual risk of injury to the Saphenous Nerve using a “closed” technique for the insertion of a TightRope. Method. 20 TightRopes were inserted into Fresh Frozen Cadavers. This was done using the senior authors preferred technique of divergent tightropes with the distal implant directed slightly anterior to the fibula-tibia axis and the proximal implant slightly posterior in order to simulate the greatest risk to the nerve. This was done under image Intensifier guidance to simulate an intraoperative environment. The medial side of the distal tibia was then dissected to directly record and measure the relationship of the TightRope to the Saphenous Nerve. Measurements were taken using digital calipers from the centre of the button on the medial side of the TightRope to the centre of the nerve at the point of closest proximity. Results. 12 TightRopes were found to exit posterior to the nerve, 7 anterior and 1 penetrated through the centre of the nerve. The mean distance from the centre of the button to the nerve was 6.99mm (range 0.72–14.52mm, standard deviation 4.33mm). In 9 of the 20 TightRopes, the nerve was found to be less than 5mm away. Conclusion. Our findings demonstrated that the risks of damaging or indeed entrapping the Saphenous nerve were high, and therefore we would advocate an open incision on the medial side with judicious exploration to ensure there is no damage to the medial neurological structures

Aims. To assess the characteristic clinical features, management, and outcome of patients who present to orthopaedic surgeons with functional dystonia affecting the foot and ankle. Methods. We carried out a retrospective search of our records from 2000 to 2019 of patients seen in our adult tertiary referral foot and ankle unit with a diagnosis of functional dystonia. Results. A total of 29 patients were seen. A majority were female (n = 25) and the mean age of onset of symptoms was 35.3 years (13 to 71). The mean delay between onset and diagnosis was 7.1 years (0.5 to 25.0). Onset was acute in 25 patients and insidious in four. Of the 29 patients, 26 had a fixed dystonia and three had a spasmodic dystonia. Pain was a major symptom in all patients, with a coexisting diagnosis of chronic regional pain syndrome (CRPS) made in nine patients. Of 20 patients treated with Botox, only one had a good response. None of the 12 patients who underwent a surgical intervention at our unit or elsewhere reported a subjective overall improvement. After a mean follow-up of 3.2 years (1 to 12), four patients had improved, 17 had remained the same, and eight reported a deterioration in their condition. Conclusion. Patients with functional dystonia typically presented with a rapid onset of fixed deformity after a minor injury/event and pain out of proportion to the deformity. Referral to a neurologist to rule out neurological pathology is advocated, and further management should be carried out in a movement disorder clinic. Response to treatment (including Botulinum toxin (Botox) injections) is generally poor. Surgery in this group of patients is not recommended and may worsen the condition. The overall prognosis remains poor. Cite this article: Bone Joint J 2021;103-B(6):1127–1132

Aims

This scoping review aims to identify patient-related factors associated with a poorer outcome following total ankle arthroplasty (TAA).

Aims

This study aimed to compare the outcomes of two different postoperative management approaches following surgical fixation of ankle fractures: traditional cast immobilization versus the Early Motion and Directed Exercise (EMADE) programme.

Introduction:. There are concerns with the use of the Shannon burr in calcaneal osteotomies entered from the lateral side, with the medial structures possibly at risk when performing the osteotomy of the medial calcaneal wall. Our aims with this study were to investigate the neurovascular relationships with the calcaneal osteotomy performed using a Shannon burr. Methods:. This study was performed at the anatomy department, University of Sussex, Brighton. There were 13 fresh frozen below knee cadaveric specimens obtained for this study. The osteotomy was performed using a Shannon burr using a minimally invasive technique. The neurovascular structures were then dissected out to analyse their relation and any damage. Results:. Laterally, there was no evidence of damage to any neurological structure in 11 feet. In two feet, a very small lateral calcaneal branch was transected. In both cases, this was a very proximal branch from the sural nerve. There were between one and five lateral calcaneal branches of the sural nerve, and a very proximal branch present in nine feet. The minimum distance from the burr to the sural nerve was 9mm. In all cases, the entry point was within 6mm of the closest lateral calcaneal branch. Medially, there was no evidence of damage to any neurovascular structure. Quadratus plantae was present in 12 of 13 feet acting as a barrier to the neurovascular structures, and was not breached by the burr, shielding the neurovascular structures from injury. There were one or two medial calcaneal nerve branches, which all crossed the osteotomy, but were not damaged. Conclusion:. The calcaneal osteotomy performed by a Shannon burr can cause possible damage to small branches of the sural nerve, but is protected by QP form causing damage to any medial structures

Introduction. In 1927, Lambrinudi described a variant triple fusion for the treatment of paralytic “drop foot”. This involved closing wedge osteotomies and fusion to correct the deformities predominantly caused by Polio. The eradication of Polio has seen a shift in its use to the correction of other complex hind foot deformities. The technique has relevance in modern Orthopaedics for other neurological and degenerate conditions. There have been few published series of this technique since 1927. We describe a series of 14 complex corrective triple arthrodeses to illustrate the power of Lambrinudi's concepts. We believe Lambrinudi's original description has relevance in terms of modern day complex hindfoot deformity correction

Introduction:. Symptomatic tarsal coalitions failing conservative treatment are traditionally managed by open resection. Arthroscopic excision of calcaneonavicular bars have previously been described as has a technique for excising talocalcaneal bars using an arthroscope to guide an open resection. We describe a purely arthroscopic technique for excising talocalcaneal coalitions. We present a retrospective two-surgeon case series of the first eight patients (nine feet). Methods:. Subtalar arthroscopy is performed from two standard sinus tarsi portals with the patient in a saggy lateral position. Coalitions are resected with a barrel burr after soft tissue clearance with arthroscopic shavers. Early postoperative mobilisation and non-steroidal anti-inflammatory drugs prevent recurrence of coalition. Outcome measures include restoration of subtalar movements, return to work and sports, visual analogue pain scales and Sports Athlete Foot and Ankle Scores (SAFAS). Follow-up ranges from 1 to 5.5 years. Results:. Pain and SAFAS scores improved in 7 patients. Subtalar movements were improved in all feet and were sustained to final follow-up. All patients achieved early good function and returned to sports and demanding jobs. One patient's pain recurred requiring subsequent fusions. One posterior tibial nerve was damaged. Both of these patients had coalitions extending across more than one quarter of the posterior facet. Conclusion:. Minimal destruction of bone and soft tissues with an arthroscopic technique allows early mobilization and minimizes pain. We acknowledge the risk of neurological damage from both open and arthroscopic excision of tarsal coalitions. Patient selection and preoperative planning are crucial to avoid relapse and complication. If significant degenerative changes are present at surgery or resections are too extensive onto the posterior facet early recurrence of pain may occur. This series from two independent surgeons supports the feasibility and effectiveness of this technique

In developed nations Charcot arthropathy is most commonly caused by diabetes mellitus. Worldwide, leprosy remains the primary cause. All evidence points to a relationship between neurologic loss, continued loading activities and the development of unrecognized bone fragmentation. In type 2 diabetes, dysregulation of leptin biology causes bone loss and may be an important factor in precipitating Charcot events. Bone density studies show massive loss of bone in patients with ankle and hindfoot Charcot problems, but not midfoot problems. This suggests a different mechanism for collapse. Stable collapse with ulcer development in the midfoot can be treated with exostectomy. Realignment and fusion remain the mainstays of treatment for diabetic Charcot neuropathy, especially in the ankle and hindfoot. Bone mineralization deficiencies require special consideration of fixation techniques. Thin wire external fixation – either as primary fixation or to reinforce/neutralize other methods can be very helpful. Large bridging screws and carefully selected bridging plates are frequently also valuable to consider. Excessive immobilization periods (often double the normal amount of time) are generally required. The goal may be limited to a braceable, plantigrade foot

Introduction. The exact action of the Peroneus Longus muscle on the foot is not fully understood. It is involved in a number of pathological processes like tendonitis, tenosynovitis, chronic rupture and neurological conditions. It is described as having a consistent insertion to the base of the first metatarsal, but there have also been reports of significant variations and additional slips. Our aim was to further clarify the anatomy of the main insertion of the Peroneus Longus tendon and to describe the site and frequency of other variable insertion slips. Methods and Materials. The course of the distal peroneus longus tendon and its variable insertion was dissected in 12 embalmed, cadaveric specimens. The surface area of the main insertion footprint and angle of insertion was measured using an Immersion Digital Microscribe and 3D mapping software. The site and frequency of the other insertion slips is also presented. Results. There was a consistent, main insertion to the infero-lateral aspect of the first metatarsal in all specimens. The only additional slip was to the medial cuneiform. This did not increase the total footprint. Discussion. The main footprint of the Peroneus Longus tendon is on the first metatarsal. There was an additional slip to the medial cuneiform in 33% of our specimens. Although we are unsure about the significance of this additional slip, we hope it will lead to a better understanding of the mechanism of action of this muscle and its role both in the normal and pathological foot

Introduction. Many common fractures are inherently stable, will not displace and do not require plaster casting to achieve union in a good position. Nevertheless, many patients with stable fractures are advised that they need a cast, despite the potential for stiffness, skin problems and thromboembolism. Attempts to challenge this practice often meet the argument that patients prefer a cast for pain relief. We analysed five years of a single consultant's fracture clinic to see how many patients with stable foot and ankle fractures chose a cast after evidence-based counselling. Materials and methods. All patients with stable fractures of the ankle or metatarsals seen between 1st June 2005 and 31st May 2010 were included. Displaced or potentially unstable ankle fractures, Jones fractures and fractures involving the Lisfranc joint were excluded. Patients were advised functional treatment but offered a cast if they wished. Patients were documented prospectively as part of a larger audit, including demographics, diagnosis and treatment in the emergency department and fracture clinic. Results. 93 patients had stable ankle fractures. One (1%) chose a cast, 77 an ankle brace and 14 the RICE regime. One was advised a cast for neurological deformity. 105 patients had fifth metatarsal fractures outside the “non-” zone. 19 (18%) chose casts and 86 followed the RICE regime. 50 patients had other stable metatarsal fractures 15 (30%) chose casts. 86% of patients had casts applied in the emergency department. Discussion. The majority of patients with stable foot and ankle fractures do not wish to wear a cast once they understand it will not affect their outcome. In many cases this decision could have been reached in the emergency department with appropriate guidelines and education, preventing patient inconvenience and possible adverse events. Conclusion. Most patients are happy with evidence-based functional treatment of stable fractures

Aims

Tibiotalocalcaneal (TTC) fusion is used to treat a variety of conditions affecting the ankle and subtalar joint, including osteoarthritis (OA), Charcot arthropathy, avascular necrosis (AVN) of the talus, failed total ankle arthroplasty, and severe deformity. The prevalence of postoperative complications remains high due to the complexity of hindfoot disease seen in these patients. The aim of this study was to analyze the relationship between preoperative conditions and postoperative complications in order to predict the outcome following primary TTC fusion.

Aims

In a randomized controlled trial with two-year follow-up, patients treated with suture button (SB) for acute syndesmotic injury had better outcomes than patients treated with syndesmotic screw (SS). The aim of this study was to compare clinical and radiological outcomes for these treatment groups after five years.

Aims

The pathogenesis of intraneural ganglion cysts is controversial. Recent reports in the literature described medial plantar intraneural ganglion cysts (mIGC) with articular branches to subtalar joints. The aim of the current study was to provide further support for the principles underlying the articular theory, and to explain the successes and failures of treatment of mICGs.

Objectives

The incidence of acute Achilles tendon rupture appears to be increasing. The aim of this study was to summarize various therapies for acute Achilles tendon rupture and discuss their relative merits.

Aims

Identifying predictors of compartment syndrome in the foot after a fracture of the calcaneus may lead to earlier diagnosis and treatment. The aim of our study was to identify any such predictors.

Objectives

The surgical challenge with severe hindfoot injuries is one of technical feasibility, and whether the limb can be salvaged. There is an additional question of whether these injuries should be managed with limb salvage, or whether patients would achieve a greater quality of life with a transtibial amputation. This study aims to measure functional outcomes in military patients sustaining hindfoot fractures, and identify injury features associated with poor function.

While many forefoot procedures may be performed as a day case, there are no specific guidelines as to which procedures are suitable. This study assessed the early post-operative pain after forefoot surgery performed a day case, compared with conventional inpatient management.

A total of 317 consecutive operations performed by a single surgeon were included in the study. Those eligible according to the criteria of the French Society of Anaesthesia (SFAR) were managed as day cases (127; 40%), while the remainder were managed as inpatients.

The groups were comparable in terms of gender, body mass index and smoking status, although the mean age of the inpatients was higher (p < 0.001) and they had higher mean American Society of Anaesthesiologists scores (p = 0.002). The most severe daily pain was on the first post-operative day, but the levels of pain were similar in the two groups; (4.2/10, sd 2.5 for day cases, 4.4/10, sd 2.4 for inpatients; p = 0.53). Overall, 28 (9%) of patients who had their surgery as a day case and 34 (11%) of inpatients reported extreme pain (≥ 8/10). There were more day case patients rather than inpatients that declared their pain disappeared seven days after the surgery (p = 0.02). One day-case patient with excessive bleeding was admitted post-operatively.

Apart from the most complicated cases, forefoot surgery can safely be performed as a day case without an increased risk of pain, or complications compared with management as an inpatient.

We report the incidence and intensity of persistent pain in patients with an otherwise uncomplicated total ankle replacement (TAR). Arthroscopic debridement was performed in selected cases and the clinical outcome was analysed.

Among 120 uncomplicated TARs, there was persistent pain with a mean visual analogue scale (VAS) of 2.7 (0 to 8). The intensity of pain decreased in 115 ankles (95.8%). Exercise or walking for more than 30 minutes was the most common aggravating factor (62 ankles, 68.1%). The character of the pain was most commonly described as dull (50 ankles, 54.9%) and located on the medial aspect of the joint (43 ankles, 47.3%).

A total of seven ankles (5.8%) underwent subsequent arthroscopy. These patients had local symptoms and a VAS for pain ≥ 7 on exertion. Impingement with fibrosis and synovitis was confirmed. After debridement, the median VAS decreased from 7 to 3 and six patients were satisfied. The median VAS for pain and the American Orthopaedic Foot and Ankle Society score of the ankles after debridement was similar to that of the uncomplicated TARs (p = 0.496 and p = 0.066, respectively).

Although TAR reduces the intensity of pain, residual pain is not infrequent even in otherwise uncomplicated TARs and soft-tissue impingement is the possible cause.

We present a review of litigation claims relating to foot and ankle surgery in the NHS in England during the 17-year period between 1995 and 2012.

A freedom of information request was made to obtain data from the NHS litigation authority (NHSLA) relating to orthopaedic claims, and the foot and ankle claims were reviewed.

During this period of time, a total of 10 273 orthopaedic claims were made, of which 1294 (12.6%) were related to the foot and ankle. 1036 were closed, which comprised of 1104 specific complaints. Analysis was performed using the complaints as the denominator. The cost of settling these claims was more than £36 million.

There were 372 complaints (33.7%) involving the ankle, of which 273 (73.4%) were related to trauma. Conditions affecting the first ray accounted for 236 (21.4%), of which 232 (98.3%) concerned elective practice. Overall, claims due to diagnostic errors accounted for 210 (19.0%) complaints, 208 (18.8%) from alleged incompetent surgery and 149 (13.5%) from alleged mismanagement.

Our findings show that the incorrect, delayed or missed diagnosis of conditions affecting the foot and ankle is a key area for improvement, especially in trauma practice.

Clinicians are often asked by patients, “When can I drive again?” after lower limb injury or surgery. This question is difficult to answer in the absence of any guidelines. This review aims to collate the currently available evidence and discuss the factors that influence the decision to allow a patient to return to driving. Medline, Web of Science, Scopus, and EMBASE were searched using the following terms: ‘brake reaction time’, ‘brake response time’, ‘braking force’, ‘brake pedal force’, ‘resume driving’, ‘rate of application of force’, ‘driving after injury’, ‘joint replacement and driving’, and ‘fracture and driving’. Of the relevant literature identified, most studies used the brake reaction time and total brake time as the outcome measures. Varying recovery periods were proposed based on the type and severity of injury or surgery. Surveys of the Driver and Vehicle Licensing Agency, the Police, insurance companies in the United Kingdom and Orthopaedic Surgeons offered a variety of opinions.

There is currently insufficient evidence for any authoritative body to determine fitness to drive. The lack of guidance could result in patients being withheld from driving for longer than is necessary, or returning to driving while still unsafe.
