Aims

This study reports updates the previously published two-year clinical, functional, and radiological results of a group of patients who underwent transfibular total ankle arthroplasty (TAA), with follow-up extended to a minimum of five years.

Methods

We prospectively evaluated 89 patients who underwent transfibular TAA for end-stage osteoarthritis. Patients’ clinical and radiological examinations were collected pre- and postoperatively at six months and then annually for up to five years of follow-up. Three patients were lost at the final follow-up with a total of 86 patients at the final follow-up.

Introduction:. Cone Based CT (CBCT) scanning uses a point source and a planar detector with parallel data acquisition and volumetric coverage of the area of interest. The pedCAT (Curvebeam USA) scanner is marketed as a low radiation dose, compact, faster and inexpensive CT scanner that can be used to obtain both non- weightbearing and true 3 dimensional weightbearing views. Method:. A review of the first 100 CBCT scanning in our unit has been performed to assess ease of scanning, imaging time, radiation dose and value of imaging as opposed to conventional imaging. Results:. A pedcat CT scan was available within minutes of the request, similar to plain radiographs but much earlier than a 6 week delay for a patient to attend a new appointment for a conventional CT. All patients returned to see the clinician for a clinical decision in the same NHS clinic and did not require a new clinic visit; illustrative cases include fracture/subluxation detection, surgical planning, extent of arthritis and 3D assessment of union of arthrodeses. All patients were able to transfer to the scanner with ease and the imaging time was 10 times than a conventional CT. The radiation dose to the patients was 9% that of a full gantry system. Weightbearing CT scanning enabled a 3D evaluation of reduction of joint space and ankle/hindfoot alignment. Anterior ankle and sesamoid impingement have been diagnosed in patients with previously obscure pain. Conclusion:. 3D Cone Beam imaging has been found to be easily accessible, rapidly performed and safer to the patient in providing a lower radiation dose. Weightbearing 3D imaging provides additional diagnostic information

Achilles tendinopathy is a common cause of disability. Despite the economic and social relevance of the problem, the causes and mechanisms of Achilles tendinopathy remain unclear. Tendon vascularity, gastrocnemius-soleus dysfunction, age, gender, body weight and height, pes cavus, and lateral ankle instability are considered common intrinsic factors. The essence of Achilles tendinopathy is a failed healing response, with haphazard proliferation of tenocytes, some evidence of degeneration in tendon cells and disruption of collagen fibres, and subsequent increase in non-collagenous matrix. Tendinopathic tendons have an increased rate of matrix remodelling, leading to a mechanically less stable tendon which is more susceptible to damage. The diagnosis of Achilles tendinopathy is mainly based on a careful history and detailed clinical examination. The latter remains the best diagnostic tool. Over the past few years, various new therapeutic options have been proposed for the management of Achilles tendinopathy. Despite the morbidity associated with Achilles tendinopathy, many of the therapeutic options described and in common use are far from scientifically based. New minimally invasive techniques of stripping of neovessels from the Kager's triangle of the tendo Achillis have been described, and seem to allow faster recovery and accelerated return to sports, rather than open surgery. A genetic component has been implicated in tendinopathies of the Achilles tendon, but these studies are still at their infancy

Introduction. Foot and ankle is a well-established and growing sub specialty in orthopaedics. It accounts for 20 to 25 per cent of an average department's workload. There are two well established foot and ankle specialist journals but for many surgeons the Journal of Bone and Surgery (JBJS) remains the preeminent journal in orthopaedics and a highly sought after target journal for publication of research. It is our belief that foot and ankle surgery is underrepresented in the JBJS. We undertook a study to test this hypothesis. Methods. We analysed all JBJS (British and American editions) volumes over a 10 year period (2001 to 2010). We recorded how many editorials, reviews, original papers and case reports were foot and ankle related. Results. of 2197 original papers published in JBJS Br only 114 (5%) were foot and ankle related. Nine out of 181 (5%) case reports, 2 out of 71 (3%) aspects of current management, none of the 51 editorials and only 3 out of 97 (3%) of reviews were foot and ankle related. In the JBJS American edition 174 out of 2117 original papers (8%), 28 out of 401 (7%) case reports, 4 out of 103 (4%) current concept reviews, 8 out of 115 (7%) instructional course lectures were foot and ankle related. Of 35 Editors on the JBJS British edition only 2 were dedicated foot and ankle surgeons, one of whom is retired. Our study reveals that foot and ankle related research accounts for a very small proportion of JBJS publications. Foot and ankle surgery needs to be proportionally represented at the editorial board level to reflect the fast growing interest in foot and ankle conditions and related research

Minimally Invasive foot surgery remains controversial. Potential benefits include a reduced incidence of wound complications, faster return to employment and normal footwear. There are no studies published regarding the results of minimally invasive dorsal cheilectomy. Patients and Methods. Thirty eight patients with painful grade I hallux rigidus underwent dorsal cheilectomy between April 2006 and June 2010. Minimally invasive cheilectomy (MIC) was introduced in August 2009. AOFAS scores, satisfaction, return to normal shoes and employment were assessed. Results. Twenty two patients had open cheilectomy (OC) whilst 16 had MIC. Mean follow-up was 6 months for the MIC group and 35 months for the OC group. Mean AOFAS score was 75/100 (SD 17) in the MIC group and 70/100 (SD 18). Patients rated their satisfaction as 9.1/10 for MIC and 8.6/10 for OC. There was no significant difference in time to return to normal shoes (P = 0.32) or employment (P = 0.07). Two patients (one MIS, one OC) had a superficial wound infection which resolved with oral antibiotics. One patient had a first metatarsophalangeal joint fusion in the MIS group. Two patients in the OC group went on to have a first metatarsophalangeal joint fusion and one underwent joint resurfacing. Discussion. These results suggest MIC has comparable early results to OC. Larger studies are required to further establish the benefits of MIC. Conclusion. Minimally invasive dorsal cheilectomy seems to offer a safe alternative to open cheilectomy with promising early results. Patient satisfaction with this procedure is very high

Introduction. Syndesmosis injuries are significant injuries and require anatomical reduction. However, stabilisation of these injuries with syndesmosis screws carries specific complications and many surgeons advocate a second operation to remove the screw. Primary Tightrope suture fixation has been shown to be an effective treatment for syndesmotic injuries and avoids the need for a second operation. Materials and Methods. A retrospective audit identified patients who were treated for syndesmosis injuries over a two year period. Theatre and clinic costs were obtained to compare the cost of syndesmosis fixation using diastasis screws with the estimated cost of primary syndesmosis fixation using a Tightrope suture. Results. 79 patients received diastasis screw fixation of syndesmosis injuries between January 2007 and January 2009. The mean number of follow up clinic appointments was 3.7 following initial surgery, and 2.2 following diastasis screw removal. Allowing for device, theatre time and clinic appointment costs, and an estimated average of 4 follow up appointments following Tightrope syndesmosis fixation, primary fixation with this device could a saving of 34 theatre slots, 68 outpatient clinic appointments, and £12,138 per year at our hospital. Discussion. Biomechanical studies have demonstrated a reduction in normal tibiotalar external rotation with the presence of a diastasis screw, and there are several published reports of complications when these screws are retained. The Tightrope suture provides reduction of the syndesmosis whilst allowing normal physiological movement at the distal tibiofibular joint and negates the need for a second operation to remove the implant. In addition there may be improvements in foot and ankle scores and a faster return to work when these devices are used compared with traditional screw fixation. Conclusion. In addition to the patient benefits, our audit suggests that there may be significant financial benefits associated with primary syndesmosis fixation with Tightrope sutures

Aims

Postoperative rehabilitation regimens following ankle arthrodesis vary considerably. A systematic review was conducted to determine the evidence for weightbearing recommendations following ankle arthrodesis, and to compare outcomes between different regimens.

Patients and Methods

MEDLINE, Web of Science, Embase, and Scopus databases were searched for studies reporting outcomes following ankle arthrodesis, in which standardized postoperative rehabilitation regimens were employed. Eligible studies were grouped according to duration of postoperative nonweightbearing: zero to one weeks (group A), two to three weeks (group B), four to five weeks (group C), or six weeks or more (group D). Outcome data were pooled and compared between groups. Outcomes analyzed included union rates, time to union, clinical scores, and complication rates.

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.

Patients and Methods

Between 2006 and 2017, five patients with five mICGs were retrospectively reviewed. There were five men with a mean age of 50.2 years (33 to 68) and a mean follow-up of 3.8 years (0.8 to 6). Case history, physical examination, imaging, and intraoperative findings were reviewed. The outcomes of interest were ultrasound and/or MRI features of mICG, as well as the clinical outcomes.

Aims

The aim of this study was to report a single surgeon series of consecutive patients with moderate hallux valgus managed with a percutaneous extra-articular reverse-L chevron (PERC) osteotomy.

Patients and Methods

A total of 38 patients underwent 45 procedures. There were 35 women and three men. The mean age of the patients was 48 years (17 to 69). An additional percutaneous Akin osteotomy was performed in 37 feet and percutaneous lateral capsular release was performed in 22 feet. Clinical and radiological assessments included the type of forefoot, range of movement, the American Orthopedic Foot and Ankle (AOFAS) score, a subjective rating and radiological parameters.

The mean follow-up was 59.1 months (45.9 to 75.2). No patients were lost to follow-up.

Injuries to the foot in athletes are often subtle and can lead to a substantial loss of function if not diagnosed and treated appropriately. For these injuries in general, even after a diagnosis is made, treatment options are controversial and become even more so in high level athletes where limiting the time away from training and competition is a significant consideration.

In this review, we cover some of the common and important sporting injuries affecting the foot including updates on their management and outcomes.

Objectives

The goals of this study were: 1) to determine if high-fat diet (HFD) feeding in female mice would negatively impact biomechanical and histologic consequences on the Achilles tendon and quadriceps muscle; and 2) to investigate whether exercise and branched-chain amino acid (BCAA) supplementation would affect these parameters or attenuate any negative consequences resulting from HFD consumption.

Methods

We examined the effects of 16 weeks of 60% HFD feeding, voluntary exercise (free choice wheel running) and BCAA administration in female C57BL/6 mice. The Achilles tendons and quadriceps muscles were removed at the end of the experiment and assessed histologically and biomechanically.

A total of seven patients (six men and one woman) with a defect in the Achilles tendon and overlying soft tissue underwent reconstruction using either a composite radial forearm flap (n = 3) or an anterolateral thigh flap (n = 4). The Achilles tendons were reconstructed using chimeric palmaris longus (n = 2) or tensor fascia lata (n = 2) flaps or transfer of the flexor hallucis longus tendon (n = 3). Surgical parameters such as the rate of complications and the time between the initial repair and flap surgery were analysed. Function was measured objectively by recording the circumference of the calf, the isometric strength of the plantar flexors and the range of movement of the ankle. The Achilles tendon Total Rupture Score (ATRS) questionnaire was used as a patient-reported outcome measure. Most patients had undergone several previous operations to the Achilles tendon prior to flap surgery. The mean time to flap surgery was 14.3 months (2.1 to 40.7).

At a mean follow-up of 32.3 months (12.1 to 59.6) the circumference of the calf on the operated lower limb was reduced by a mean of 1.9 cm (sd 0.74) compared with the contralateral limb (p = 0.042). The mean strength of the plantar flexors on the operated lower limb was reduced to 88.9% of that of the contralateral limb (p = 0.043). There was no significant difference in the range of movement between the two sides (p = 0.317). The mean ATRS score was 72 points (sd 20.0). One patient who had an initial successful reconstruction developed a skin defect of the composite flap 12 months after free flap surgery and this resulted in recurrent infections, culminating in transtibial amputation 44 months after reconstruction.

These otherwise indicate that reconstruction of the Achilles tendon combined with flap cover results in a successful and functional reconstruction.

It has been suggested that extracorporeal shockwave therapy is a safe and effective treatment for pain relief from recalcitrant plantar fasciopathy (PF). However, the changes in gait and associated biomechanical parameters have not been well characterised. We recruited 12 female patients with recalcitrant PF who had a mean age of 59 years (50 to 70) and mean body mass index of 25 kg/m2 (22 to 30). The patients reported a mean duration of symptoms of 9.3 months (6 to 15). Shockwave therapy consisting of 1500 impulses (energy flux density 0.26 mJ/mm2) was applied for three sessions, each three weeks apart. A pain visual analogue scale (VAS) rating, plantar pressure assessment and motion analysis were carried out before and nine weeks after first shock wave therapy. It was demonstrated that patients increased their walking velocity and cadence as well indicating a decrease in pain after shockwave therapy. In the symptomatic foot, the peak contact pressure over the forefoot increased and the contact area over the digits decreased. The total foot impulse also decreased as did stance duration. The duration the centre of pressure remained in the hindfoot increased in the symptomatic foot after shockwave therapy. The differences in centre of pressure trajectory at baseline decreased at final follow-up. In conclusion, shockwave therapy not only decreased the pain VAS rating but also improved the gait parameters of the symptomatic foot in PF patients.

Objectives

To evaluate the applicability of MRI for the quantitative assessment of anterior talofibular ligaments (ATFLs) in symptomatic chronic ankle instability (CAI).

Methods

Between 1997 and 2010, 39 patients with symptomatic CAI underwent surgical treatment (22 male, 17 female, mean age 25.4 years (15 to 40)). In all patients, the maximum diameters of the ATFLs were measured on pre-operative T2-weighted MR images in planes parallel to the path of the ATFL. They were classified into three groups based on a previously published method with modifications: ‘normal’, diameter = 1.0 - 3.2 mm; ‘thickened’, diameter > 3.2 mm; ‘thin or absent’, diameter < 1.0 mm. Stress radiography was performed with the maximum manual force in inversion under general anaesthesia immediately prior to surgery. In surgery, ATFLs were macroscopically divided into two categories: ‘thickened’, an obvious thickened ligament and ‘thin or absent’. The imaging results were compared with the macroscopic results that are considered to be of a gold standard.

Van Nes rotationplasty may be used for patients with congenital proximal focal femoral deficiency (PFFD). The lower limb is rotated to use the ankle and foot as a functional knee joint within a prosthesis. A small series of cases was investigated to determine the long-term outcome. At a mean of 21.5 years (11 to 45) after their rotationplasty, a total of 12 prosthetic patients completed the Short-Form (SF)-36, Faces Pain Scale-Revised, Harris hip score, Oswestry back pain score and Prosthetic Evaluation Questionnaires, as did 12 age- and gender-matched normal control participants. A physical examination and gait analysis, computerised dynamic posturography (CDP), and timed ‘Up & Go’ testing was also completed. Wilcoxon Signed rank test was used to compare each PFFD patient with a matched control participant with false discovery rate of 5%.

There were no differences between the groups in overall health and well-being on the SF-36. Significant differences were seen in gait parameters in the PFFD group. Using CDP, the PFFD group had reduced symmetry in stance, and reduced end point and maximum excursions.

Patients who had undergone Van Nes rotationplasty had a high level of function and quality of life at long-term follow-up, but presented with significant differences in gait and posture compared with the control group.

The aim of this study was to compare the outcome of bilateral sequential total ankle replacement (TAR) with that of unilateral TAR. We reviewed 23 patients who had undergone sequential bilateral TAR under a single anaesthetic and 46 matched patients with a unilateral TAR. There were no significant pre-operative differences between the two groups in terms of age, gender, body mass index, American Society of Anaesthesiologists classification and aetiology of the osteoarthritis of the ankle. Clinical and radiological follow-up was carried out at four months, one and two years.

After four months, patients with simultaneous bilateral TAR reported a significantly higher mean pain score than those with a unilateral TAR. The mean American Orthopaedic Foot and Ankle Society hindfoot score and short-form 36 physical component summary score were better in the unilateral group. However, this difference disappeared at the one-and two-year follow-ups.

Bilateral sequential TAR under one anaesthetic can be offered to patients with bilateral severe ankle osteoarthritis. However, they should be informed of the long recovery period.

There are few data available regarding the association between hallux valgus and pain or functional limitation. We determined the prevalence of hallux valgus in a rural Korean population aged between 40 and 69 years, and its association with pain and function. A total of 563 subjects was examined using the foot health status questionnaire, the Short Form-36 questionnaire and weight-bearing anteroposterior radiographs.

Hallux valgus was present in 364 subjects (64.7%). It did not significantly correlate with age and was more common in women. Of the 364 subjects, 48 (13.2%) had moderate or greater deformity, defined as a hallux valgus angle > 25°. This was significantly associated with pain, worse function and worse foot health. The putative risk factors associated with painful hallux valgus were female gender, low educational attainment and the presence of pain in the knee.

We studied a cohort of 26 diabetic patients with chronic ulceration under the first metatarsal head treated by a modified Jones extensor hallucis longus and a flexor hallucis longus transfer. If the first metatarsal was still plantar flexed following these two transfers, a peroneus longus to the peroneus brevis tendon transfer was also performed. Finally, if ankle dorsiflexion was < 5° with the knee extended, a Strayer-type gastrocnemius recession was performed.

The mean duration of chronic ulceration despite a minimum of six months’ conservative care was 16.2 months (6 to 31). A total of 23 of the 26 patients were available for follow-up at a mean of 39.6 months (12 to 61) after surgery. All except one achieved complete ulcer healing at a mean of 4.4 weeks (2 to 8) after surgery, and there was no recurrence of ulceration under the first metatarsal.

We believe that tendon balancing using modified Jones extensor hallucis longus and flexor hallucis longus transfers, associated in selected cases with a peroneus longus to brevis transfer and/or Strayer procedure, can promote rapid and sustained healing of chronic diabetic ulcers under the first metatarsal head.

We undertook a retrospective review of 24 arthroscopic procedures in patients with symptomatic ossicles around the malleoli of the ankle. Most of the patients had a history of injury and localised tenderness in the area coinciding with the radiological findings. Contrast-enhanced three-dimensional fast-spoiled gradient-echo MRI was performed and the results compared with the arthroscopic findings. An enhanced signal surrounding soft tissue corresponding to synovial inflammation and impingement was found in 20 patients (83%). The arthroscopic findings correlated well with those of our MRI technique and the sensitivity was estimated to be 91%. At a mean follow-up of 30.5 months (20 to 86) the mean American Orthopaedic Foot and Ankle Society score improved from 74.5 to 93 points (p < 0.001). Overall, the rate of patient satisfaction was 88%.

Our results indicate that symptomatic ossicles of the malleoli respond well to arthroscopic treatment.
