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:

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. A total of 97 patients with acute syndesmotic injury were randomized to SS or SB. The five-year follow-up rate was 81 patients (84%). The primary outcome was the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle Hindfoot Scale. Secondary outcome measures included Olerud-Molander Ankle (OMA) score, visual analogue scale (VAS), EuroQol five-dimension questionnaire (EQ-5D), range of movement, complications, reoperations, and radiological results. CT scans of both ankles were obtained after surgery, and after one, two, and five years.Aims

Introduction. Aneurysmal bone cysts commonly found in lower limbs are locally aggressive masses that can lead to bony erosion, instability and fractures. This has major implications in the lower limbs especially in paediatric patients, with potential growth disturbance and deformity. In this case series we describe radical aneurysmal bone cyst resection and lower limb reconstruction using cable transport and

Syndesmotic ankle injuries are present in one fourth of all ankle trauma and may lead to chronic syndesmotic instability as well as posttraumatic ankle osteoarthritis. The main challenge remains distinguishing them from other types of ankle trauma. Currently, the patient's injured and non-injured ankles are compared using plain radiographs to determine pathology. However, these try to quantify 3D displacement using 2D measurements techniques and it is unknown to what extent the 3D configuration of the normal ankle
The incisura fibularis (IF) provides intrinsic stability to the ankle joint complex by interlocking the distal tibia and fibula. Despite a high frequency of ligamentous ankle injuries, scant attention has been given to the morphology of the IF morphology incisura fibularis in the onset and development of these lesions. Therefore, we systematically reviewed the relation between ligamentous ankle disorders and the morphometrics of the IF. A systematic literature search was conducted on following databases: PubMed, Embase and Web of Science. Search terms consisted of ‘ankle trauma’, ‘ankle injury’, ‘ankle sprain’, ‘ankle fracture’, ‘tibiofibular’, ‘fibular notch’, ‘fibular incisura’, ‘incisura fibularis’, ‘morphometric analysis’, ‘ankle

Introduction. Ankle fractures represent approximately 10% of the fracture workload and are projected to increase due to ageing population. We present our 5 years outcome review post-surgical management of ankle fractures in a large UK Trauma unit. Methods. A total of 111 consecutive patients treated for an unstable ankle fracture were entered into a database and prospectively followed up. Baseline patient characteristics, complications, further intervention including additional surgery, functional status were recorded during five-year follow-up. Pre-injury and post-fixation functional outcome measures at 2-years were assessed using Olerud-Molander Ankle Scores (OMAS) and Lower Extremity Functional Scales (LEFS). A p value < 0.05 was considered significant. Results. The mean age was 46 with a male:female ratio of 1:1.1. The distribution of comorbidities was BMI >30 (25%), diabetes (5%), alcohol consumption >20U/week (15%) and smoking (26%). Higher BMI was predictive of worse post-op LEFS score (p = 0.02). Between pre-injury and post fixation functional scores at 2 years, there was a mean reduction of 26.8 (OMAS) and 20.5(LEFS). Using very strict radiological criteria, 31 (28%) had less than anatomical reduction of fracture fragments intra-operatively. This was, however, not predictive of patients' functional outcome in this cohort. Within 5-year period, 22 (20%) patients had removal of metalwork from their ankle, with majority 13 (59%) requiring syndesmotic screw removal. Further interventions included: joint injection (3), deltoid reconstruction (1), arthroscopic debridement (1), superficial sinus excision (2), and conversion to hindfoot nail due to failure of fixation (1). Reduction in OMAS was predictive of patients' ongoing symptoms (p=0.01). Conclusion. There is a significant reduction in functional outcome after ankle fracture fixation and patients should be counselled appropriately. Need for removal of metalwork is higher in patients who require
Aims. Tibial plateau fractures (TPFs) are complex injuries around the knee caused by high- or low-energy trauma. In the present study, we aimed to define the distribution and frequency of TPF lines using a 3D mapping technique and analyze the rationalization of divisions employed by frequently used classifications. Methods. In total, 759 adult patients with 766 affected knees were retrospectively reviewed. The TPF fragments on CT were multiplanar reconstructed, and virtually reduced to match a 3D model of the proximal tibia. 3D heat mapping was subsequently created by graphically superimposing all fracture lines onto a tibia template. Results. The cohort included 405 (53.4%) cases with left knee injuries, 347 (45.7%) cases with right knee injuries, and seven (0.9%) cases with bilateral injuries. On mapping, the hot zones of the fracture lines were mainly concentrated around the anterior cruciate ligament insertion, posterior cruciate ligament insertion, and the inner part of the lateral condyle that extended to the junctional zone between Gerdy’s tubercle and the tibial tubercle. Moreover, the cold zones were scattered in the posteromedial fragment, superior tibiofibular

The quest for optimal treatment of acute distal tibiofibular syndesmotic disruptions is still in progress. Using suture-button repair devices is one of the dynamic stabilization options, however, they may not be always appropriate for stabilization of length-unstable syndesmotic injuries. Recently, a novel screw-suture repair system was developed to address such issues. The aim of this study was to investigate the performance of the novel screw-suture repair system in comparison to a suture-button stabilization of unstable syndesmotic injuries. Eight pairs of human cadaveric lower legs were CT scanned under 700 N single-leg axial loading in five foot positions – neutral, 15° external/internal rotation and 20° dorsi-/plantarflexion – in 3 different states: (1) pre-injured (intact); (2) injured, characterized by complete

Blount's disease is by far common cause of significant genu varum in paediatric age group. The deformity can range from simple varus deformity to significant varus, shortening of tibia and internal torsion of tibia, depending up on type and stage of Blount's disease. Several studies have shown excellent correction with the use of circular frame. The trend has moved from Ilizarov circular frame to Taylor Spatial Frame. The most accepted method of achieving correction of all components is by performing proximal tibial osteotomy and gradual correction of mechanical axis. Traditionally two additional procedures – fibular osteotomy and fixation of distal tibio-fibular
