Background

The focus on evidence-based medicine has led to calls for increased levels of evidence in surgical journals. The purpose of the present study was to review the levels of evidence in articles published in the foot and ankle literature and to assess changes in the level of evidence over a decade.

Methods

All articles from the years 2000 and 2010 in Foot and Ankle International, Foot and Ankle Surgery, and all foot and ankle articles from JBJS A and JBJS B were analysed. Animal, cadaveric, basic science, editorials, surveys, letters to Editor and correspondence were excluded. Articles were ranked by a five-point level of evidence scale, according to guidelines from the Centre for Evidence Based Medicine.

Introduction

Calcaneal osteotomy is often performed together with other procedures to correct hindfoot deformity. There are various methods of fixation ranging from staples, headed or headless screws or more recently stepped locking plates. It is not clear if one method is superior to the other. In this series we compare the outcome of various methods of fixation with particular attention to the need for subsequent hardware removal.

Patients and Methods

A retrospective review of the records of a consecutive series of patients who had a calcaneal osteotomy performed in our unit within the last 5 years was undertaken. All patients had had their osteotomy through an extended lateral approach to their calcaneous. The subsequent fixation was performed using one of three methods; a lateral plate placed through the same incision; a ‘headless’; or a ‘headed’ screw through a separate stab incision inserted through the infero-posterior heel. Records were kept of subsequent symptoms from the hardware and need for metalwork removal as well as any complications. When screws were inserted the entry point in relation to the weight-bearing surface of the calcaneous was also recorded.

Background

The recent emphasis on using “evidence based medicine” for decision-making in patient care has prompted many publishers to mention the level of evidence of articles in their journals. The “quality” of a journal may thus be reflected by the proportion of articles with high levels of evidence and assist it achieve citations and therefore an Impact Factor.

The purpose of this study was to survey published Foot and Ankle literature to evaluate changes in the level of evidence over ten years.

Methods

Articles from Foot and Ankle International, JBJS Br, JBJS Am, Foot and Foot and Ankle Surgery were used. We looked at the years 2000 and 2010 and ranked the articles by a five-point level of evidence scale, according to guidelines from the Centre for Evidence Based Medicine. 498 articles were ranked. Studies of animals, studies of cadavera, basic-science articles were excluded.

Introduction

Bone marrow oedema syndrome (BMES) of the foot and ankle is an uncommon and often misdiagnosed condition. It is usually thought to be a benign self limiting condition, without any sequelae. However, it can cause disabling pain for a prolonged period of time.

Materials and Methods

We retrospectively reviewed 8 patients with the diagnosis of BMES. There were 6 males and 2 females with an average age of 51 years (38–63 years). All patients had acute onset of severe pain in the foot without any history of trauma. None of the patients had history of excessive alcohol or steroid intake. 5 patients (63%) had bilateral involvement of migratory nature. All patients had characteristic features on MR scans, with involvement of 3 or more bones in the foot.

Single stage total talectomy with tibio-calcaneal arthrodesis in adult patients has been rarely reported in the literature. In patients with severe rigid, unbraceable equinovarus deformities, talectomy can offer excellent correction.

We performed single stage total talectomy with tibiocalcaneal arthrodesis on 11 feet in 10 patients (6F; 5M) of average age 67 years (range 54–77 years). 6 patients had neuropathic deformity, 2 had failed fusion procedures and 2 had severe Rheumatoid hindfoot disease. The fusion was undertaken using a hindfoot nail and screws in 5 patients, plate and screws in 4 patients, a hindfoot nail in 1 and cancellous screws in 1 patient. All patients followed the standard post operative protocol and were reviewed at 2, 6 and 12 weeks and thereafter every 4 weekly till union. All patients were mobilised strictly non weight bearing for the first 6 weeks and thereafter, touch weight bearing was allowed with the leg in a protective cast. Full weight bearing was allowed once the fusion had consolidated.

Fusion was achieved in 7 feet (64%) at an average time of 17 weeks. In 4 patients, non-union persisted but they were pain free at latest review and would not consider further surgery. Average duration of follow-up was 20 months (range 6–24 months). All patients had stiff hindfeet with a jog of movement at the tibio navicular articulation. All patients had a stable, plantigrade, braceable foot and were community ambulators. All patients were satisfied with the outcome.

Total talectomy with tibiocalcaneal arthrodesis is a useful procedure to correct severe rigid equinovarus deformities in adults. The tibionavicular articulation forms a pseudarthrosis and retains a jog of movement. Retention of the head of the talus with talotibial arthrodesis is unnecessary. We recommend this procedure as a salvage option in this difficult problem.

Skeletal Cryptococcosis although rare has been reported in immunodeficient individuals and in particular those with HIV. We present a case in a HIV- negative patient who presented to the London Sarcoma service masquerading as a primary bone tumour and review the relevant literature.

A 71 year old lady presented with a three month history of right submammary pain associated with a new lump. Chest radiographs showed an osteolytic lesion in the right 6th rib. CT scans demonstrated mediastinal lymphadenopathy and numerous lung nodules. Differential diagnosis of the lesion included TB abscess, myeloma, lymphoma or as a primary lung tumour presenting with hilar lymphadenopathy and necrotic skeletal metastasis. CT guided biopsy was performed with histology showing necrotising granulomatous inflammation with numerous yeast like organisms in keeping with Cryptococcus fungal infection. She was treated successfully with a six week course of voriconazole.

Cryptococcal skeletal infections can cause significant morbidity and mortality and should be considered as a rare cause of lytic osseous lesions.

Background: Isolated Gastrocnemius contracture has been implicated as the cause of a number of foot and ankle conditions. Plantar Fasciitis (PF) is one such condition that can be secondary to altered foot biomechanics as a result of gastrocnemius contracture. We perform an isolated proximal medial head of gastrocnemius release (PMGR) as a day-case procedure. This is to report our results of this procedure in the treatment of recalcitrant PF.

Material and Methods: We prospectively followed a consecutive series of 22 heels in 18 patients following a PMGR. To be included, at least one year of conservative treatment must have been tried and isolated Gastrocnemius contracture confirmed clinically using Silfverskiold’s test pre-operatively. Outcome measures included the visual analogue pain score (VAS) and a 5-point Likert scale of postoperative success. Subjective and objective calf weakness was also evaluated. Final follow up was at an average of 25 months (range: 12 to 36 months) after the surgery.

Results: Two patients were lost to follow up. In the remaining 20 heels the average VAS for pain had improved from 9.4 to 1.8 (P< 0.001). Fourteen heels (70%) were pain free or significantly better at final follow up. There was no objective evidence of calf weakness and only one patient (5%) felt subjectively weaker on the released side. There were no ‘major’ complications and only 2 cases (10%) suffered a ‘minor’ complication. One was a case of superficial wound sepsis and the other was of prolonged calf pain following the surgery. Both resolved spontaneously and without further intervention.

Conclusions: A PMGR is a simple way of treating patients with PF who fail to respond to conservative management. The results, in our series, have been favorable and the morbidity low. We recommend the use of gastrocnemius release once non-operative management has failed.

Scoliosis and hip subluxation/dislocation are common and often coexistent problems encountered in patients with cerebral palsy (CP). The underlying mechanism may be related to muscle imbalance. Surgical correction may become necessary in severe symptomatic cases. The effect of surgical correction of one deformity on the other is not well understood.

We retrospectively reviewed a series of 17 patients with total body cerebral palsy with diagnoses of both scoliosis and hip subluxation who had undergone either surgical correction of their scoliosis (9 patients) or a hip reconstruction to correct hip deformity (8 patients). In all patients, the degree of progression of both deformities was measured, radiographically, using the Cobb angle for the spine and the percentage migration index for hip centre of rotation at intervals before and at least 18 months post surgery.

All patients who underwent scoliosis correction had a progressive increase in the percentage of hip migration at a rate greater than that prior to scoliosis surgery. Similarly, patients who underwent a hip reconstruction procedure demonstrated a more rapid increase in their spine Cobb angles post surgery.

There may be a relationship between hip subluxation/dislocation and scoliosis in CP patients. Surgery for either scoliosis or hip dysplasia may in the presence of both conditions lead to a significant and rapid worsening of the other. The possible negative implications on the overall functional outcome of the surgical procedure warrants careful consideration to both hip and the spine before and after surgical correction of either deformity. In selected cases there may be an indication for one procedure to follow soon after the other.

Introduction: Impingement syndrome has been reported to occur in a proportion of patients (9%) following whiplash injuries to the neck. In this study we aim to examine this finding to establish the association and incidence of subacromial impingement following whiplash injuries to the cervical spine.

Method and results: We examined 219 patients who had presented to a single surgeon for a medico-legal report, at an average of 13.8 months (range 1–52) following a whiplash injury to the neck. All patients were assessed for clinical evidence of subacromial impingement. The patients were asked if the symptoms had developed following their neck injury and those with past history of shoulder pain were identified and excluded. 56 patients (26%) had shoulder pain following the injury; of these, 11 (5%) had clinical evidence of impingement syndrome, however in the majority other clinicians had overlooked this. The seatbelt shoulder (driver’s right and front passenger’s left) was involved in 9 (82%) of the cases (p< 0.001). The average age was 38.2 years compared with 57.8 years in those with subacromial impingement (p< 0.05). Impingement is therefore likely to be due to direct trauma from the seatbelt in the older age group with an already compromised subacromial space.

Conclusion: It is now established that subacromial impingement occurs following whiplash injuries to the neck. This is however, frequently overlooked and shoulder pain is attributed to pain radiating from the neck. It is important that this is appreciated and patients are specifically examined for signs of impingement so that appropriate treatment can be instigated. Direct trauma from the seatbelt is one likely explanation for this association.
