To assess the characteristic clinical features, management, and outcome of patients who present to orthopaedic surgeons with functional dystonia affecting the foot and ankle. 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.Aims
Methods
The purpose of this study is to examine the adductus impact on the second metatarsal by the nonosteotomy nonarthrodesis syndesmosis procedure for the hallux valgus deformity correction, and how it would affect the mechanical function of the forefoot in walking. For correcting the metatarsus primus varus deformity of hallux valgus feet, the syndesmosis procedure binds first metatarsal to the second metatarsal with intermetatarsal cerclage sutures. We reviewed clinical records of a single surgical practice from its entire 2014 calendar year. In total, 71 patients (121 surgical feet) qualified for the study with a mean follow-up of 20.3 months (SD 6.2). We measured their metatarsus adductus angle with the Sgarlato’s method (SMAA), and the intermetatarsal angle (IMA) and metatarsophalangeal angle (MPA) with Hardy’s mid axial method. We also assessed their American Orthopaedic Foot & Ankle Society (AOFAS) clinical scale score, and photographic and pedobarographic images for clinical function results.Aims
Methods
Various radiological parameters are used to evaluate a flatfoot
deformity and their measurements may differ. The aims of this study
were to answer the following questions: 1) Which of the 11 parameters
have the best inter- and intraobserver reliability in a standardized
radiological setting? 2) Are pre- and postoperative assessments
equally reliable? 3) What are the identifiable sources of variation? Measurements of the 11 parameters were recorded on anteroposterior
and lateral weight-bearing radiographs of 38 feet before and after
surgery for flatfoot, by three observers with different experience
in foot surgery (A, ten years; B, three years; C, third-year orthopaedic
resident). The inter- and intraobserver reliability was calculated.Aims

Aims. The purpose of this study was to analyse the biomechanics of
walking, through the ground reaction forces (GRF) measured, after
first metatarsal osteotomy or metatarsophalangeal joint (MTP) arthrodesis. Patients and Methods. A total of 19 patients underwent a Scarf osteotomy (50.3 years,
standard deviation (. sd. ) 12.3) and 18 underwent an arthrodesis
(56.2 years,. sd. 6.5). Clinical and radiographical data
as well as the American Orthopaedic Foot and Ankle Society (AOFAS)
scores were determined. GRF were measured using an instrumented
treadmill. A two-way model of analysis of variance (ANOVA) was used
to determine the effects of surgery on biomechanical parameters
of walking, particularly propulsion. Results. Epidemiological, radiographical and clinical data were comparable
in the two groups and better restoration of propulsive function
was found after osteotomy as shown by ANOVA (two way: surgery ×
foot) with a surgery effect on vertical forces (p <
0.01) and
a foot effect on anteroposterior impulse (p = 0.01). Conclusion. Patients who underwent Scarf osteotomy had a gait pattern similar
to that of their non-operated foot, whereas those who underwent
arthrodesis of the first (metatarsophalangeal) MTP joint did not
totally recover the propulsive forces of the forefoot. Take home message: The main findings of this study were that

This study sought to determine the medium-term
patient-reported and radiographic outcomes in patients undergoing
surgery for hallux valgus. A total of 118 patients (162 feet) underwent
surgery for hallux valgus between January 2008 and June 2009. The
Manchester-Oxford Foot Questionnaire (MOXFQ), a validated tool for
the assessment of outcome after surgery for hallux valgus, was used
and patient satisfaction was sought. The medical records and radiographs
were reviewed retrospectively. At a mean of 5.2 years (4.7 to 6.0)
post-operatively, the median combined MOXFQ score was 7.8 (IQR:0
to 32.8). The median domain scores for pain, walking/standing, and social
interaction were 10 (IQR: 0 to 45), 0 (IQR: 0 to 32.1) and 6.3 (IQR:
0 to 25) respectively. A total of 119 procedures (73.9%, in 90 patients)
were reported as satisfactory but only 53 feet (32.7%, in 43 patients)
were completely asymptomatic. The mean (SD) correction of hallux
valgus, intermetatarsal, and distal metatarsal articular angles was
18.5° (8.8°), 5.7° (3.3°), and 16.6° (8.8°), respectively. Multivariable
regression analysis identified that an American Association of Anesthesiologists
grade of >
1 (Incident Rate Ratio (IRR) = 1.67, p-value = 0.011)
and recurrent deformity (IRR = 1.77, p-value = 0.003) were associated
with significantly worse MOXFQ scores. No correlation was found
between the severity of deformity, the type, or degree of surgical
correction and the outcome. When using a validated outcome score
for the assessment of outcome after surgery for hallux valgus, the
long-term results are worse than expected when compared with the
short- and mid-term outcomes, with 25.9% of patients dissatisfied
at a mean follow-up of 5.2 years. Cite this article:
Metatarsus primus varus deformity correction
is one of the main objectives in hallux valgus surgery. A ‘syndesmosis’
procedure may be used to correct hallux valgus. An osteotomy is
not involved. The aim is to realign the first metatarsal using soft
tissues and a cerclage wire around the necks of the first and second
metatarsals. We have retrospectively assessed 27 patients (54 feet) using
the American Orthopaedic Foot and Ankle Society (AOFAS) score, radiographs
and measurements of the plantar pressures after bilateral syndesmosis
procedures. There were 26 women. The mean age of the patients was
46 years (18 to 70) and the mean follow-up was 26.4 months (24 to
33.4). Matched-pair comparisons of the AOFAS scores, the radiological
parameters and the plantar pressure measurements were conducted
pre- and post-operatively, with the mean of the left and right feet.
The mean AOFAS score improved from 62.8 to 94.4 points (p <
0.001).
Significant differences were found on all radiological parameters
(p <
0.001). The mean hallux valgus and first intermetatarsal
angles were reduced from 33.2° (24.3° to 49.8°) to 19.1° (10.1°
to 45.3°) (p <
0.001) and from 15.0° (10.2° to 18.6°) to 7.2°
(4.2° to 11.4°) (p <
0.001) respectively. The mean medial sesamoid
position changed from 6.3(4.5 to 7) to 3.6 (2 to 7) (p <
0.001)
according to the Hardy’s scale (0 to 7). The mean maximum force
and the force–time integral under the hallux region were significantly
increased by 71.1% (p = 0.001), (20.57 (0.08 to 58.3) to 35.20 (6.63
to 67.48)) and 73.4% (p = 0.014), (4.44 (0.00 to 22.74) to 7.70
(1.28 to 19.23)) respectively. The occurrence of the maximum force
under the hallux region was delayed by 11% (p = 0.02), (87.3% stance
(36.3% to 100%) to 96.8% stance (93.0% to 100%)). The force data
reflected the restoration of the function of the hallux. Three patients
suffered a stress fracture of the neck of the second metatarsal.
The short-term results of this surgical procedure for the treatment
of hallux valgus are satisfactory. Cite this article:

The purpose of this study was to compare the
results of proximal and distal chevron osteotomy in patients with moderate
hallux valgus. We retrospectively reviewed 34 proximal chevron osteotomies without
lateral release (PCO group) and 33 distal chevron osteotomies (DCO
group) performed sequentially by a single surgeon. There were no
differences between the groups with regard to age, length of follow-up,
demographic or radiological parameters. The clinical results were
assessed using the American Orthopaedic Foot and Ankle Society (AOFAS)
scoring system and the radiological results were compared between
the groups. At a mean follow-up of 14.6 months (14 to 32) there were no significant
differences in the mean AOFAS scores between the DCO and PCO groups
(93.9 (82 to 100) and 91.8 (77 to 100), respectively; p = 0.176).
The mean hallux valgus angle, intermetatarsal angle and sesamoid
position were the same in both groups. The metatarsal declination
angle decreased significantly in the PCO group (p = 0.005) and the
mean shortening of the first metatarsal was significantly greater
in the DCO group (p <
0.001). We conclude that the clinical and radiological outcome after
a DCO is comparable with that after a PCO; longer follow-up would
be needed to assess the risk of avascular necrosis. Cite this article:
This study assessed if transfer of the extensor hallucis longus is a valid alternative treatment to split transfer of the tibialis anterior tendon in adult hemiplegic patients without overactivity of the tibialis anterior. One group of 15 patients had overactivity of tibialis anterior in the swing phase, and underwent the split transfer. A further group of 14 patients had no overactivity of tibialis anterior, and underwent transfer of extensor hallucis longus. All patients had lengthening of the tendo Achillis and tenotomies of the toe flexors. All were evaluated clinically and by three-dimensional gait analysis pre- and at one year after surgery. At this time both groups showed significant reduction of disability in walking. Gait speed, stride length and paretic propulsion had improved significantly in both groups. Dorsiflexion in the swing phase, the step length of the healthy limb and the step width improved in both groups, but only reached statistical significance in the patients with transfer of the extensor hallucis longus. There were no differences between the groups at one year after operation. When combined with lengthening of the tendo Achillis, transfer of the extensor hallucis longus can be a valid alternative to split transfer of the tibialis anterior tendon to correct equinovarus foot deformity in patients without overactivity of tibialis anterior.
Rocker bottom deformity may occur during the conservative treatment of idiopathic congenital clubfoot. Between 1975 and 1996, we treated 715 patients (1120 clubfeet) conservatively. A total of 23 patients (36 feet; 3.2%) developed a rocker bottom deformity. It is these patients that we have studied. The pathoanatomy of the rocker bottom deformity is characterised by a plantar convexity appearing between three and six months of age with the hindfoot equinus position remaining constant. The convexity initially involves the medial column, radiologically identified by the talo-first metatarsal angle and secondly by the lateral column, revealed radiologically as the calcaneo-fifth metatarsal angle. The apex of the deformity is usually at the midtrasal with a dorsal calcaneocuboid subluxation. Ideal management of clubfoot deformity should avoid this complication, with adequate manipulation and splinting and early Achilles’ percutaneous tenotomy if plantar convexity occurs. Adequate soft-tissue release provides satisfactory correction for rocker bottom deformity. However, this deformity requires more extensive and complex procedures than the standard surgical treatment of clubfoot. The need for lateral radiographs to ensure that the rocker bottom deformity is recognised early, is demonstrated.
