Though there are many techniques utilised in the correction of hallux valgus (HV), no single approach has been reported to be ideal for all patients to date. A great deal of controversy remains concerning the type of osteotomy, method of fixation, and inclusion of soft tissue procedures. Herein, we compared the outcomes of two different operative techniques, the minimally-invasive modified percutaneous technique and the distal chevron osteotomy, used to treat mild to moderate hallux valgus. This study was conducted in line with the CONSORT 2010 guidelines. 41 patients (58 feet) with mild to moderate hallux valgus were randomly assigned by computer to two different groups. The first group containing 24 patients (33 feet) was treated by the modified percutaneous technique, whereas the second group included 17 patients (25 feet) treated by distal chevron osteotomy. In the modified percutaneous group, after a mean follow up of 43 months, the mean correction of hallux valgus angle (HVA) was 26.69° (P=0.00001), the mean correction of intermetatarsal angle (IMA) was 9.45° (P=0.00001), and the mean improvement of AOFAS score was 47.94 points (P=0.00001). In the chevron osteotomy group, after a mean follow up of 44 months, the mean correction of hallux valgus angle was 26.72° (P=0.00001), the mean correction of intermetatarsal angle was 9° (P=0.00001), and the mean improvement of AOFAS score was 44.76 points (P=0.00001). In our study, the modified percutaneous technique proved to be equally effective as the distal chevron osteotomy, but with fewer complications and a higher rate of patient satisfaction

Background. In the adolescent population, operative management of hallux-valgus is controversial. Operations may be less successful than in adults and post-operative recurrence is more common before full skeletal maturity. This study assesses the radiographic, functional and qualitative outcomes of surgical Hallux Valgus correction in adolescents. Methods. Three independent reviewers retrospectively analysed pre and post-operative radiological markers of hallux valgus severity for 44 operations on patients age 13–18. The patient cohort were also asked the Manchester-Oxford foot questionnaire (MOXFQ) to assess functional outcome via telephone interview and patient notes were reviewed for any evidence of complications. Results. There was no evidence of NICE recognised complications from any of the operations performed, however there was persistence or recurrence in 20.8%, requiring a second operation in 10.3%. Radiologically, all operations performed resulted in a reduction in hallux valgus severity. The hallux valgus angle showed a mean reduction of 18.0 degrees (16.3–19.7) and the inter-metatarsal angle by 7.3 degrees (6.55–8.14). 93% of operations resulted in a good MOXFQ outcome score of less than 20 out of a possible 80 negative functional outcome points. This score worsened with age in a statistically significant manner (p=0.03) but had no significant correlation with BMI. Conclusion. Surgical correction of adolescent hallux valgus reduces the radiographic severity, which correlates with good long term outcome. This surgery provides beneficial results to the patient, however there is a high recurrence rate, correlating with younger age and this must be taken into account

Background. Patient reported outcomes/experience measures have been a fundamental part of the NHS since 2009. Osteotomy procedures for hallux valgus produce varied outcomes due to their subjective nature. We used PROMS2.0, a semi-automated web-based system, which allows collection and analysis of outcome data, to assess what the patient reported outcome/experience measures for scarf+/− akin osteotomy for hallux valgus are at UHSM. Methods. Prospective PROMS data was collected from November 2012 to February 2015. Scores used to asses outcomes included EQ-5D VAS, EQ-5D Health Index, and MOxFQ, collected pre-operatively and post-operatively. Patient Personal Experience (PPE-15) was collected postoperatively. Results. 40 patients (35F/5M) (19LT +21RT) had undergone an osteotomy. Average age was 60.7 years (Range 29–88). No bilateral procedures. The pre-op average MOXFQ scores for pain, walking and social interaction were: 51.6 (range 5–100), 51.4 (range 0–96) and 48.8 (range 0–100) respectively. Post operatively these improved to 24.4 (range 0–100), 22.9 (range 0–86) and 23.1 (range 0–88). All statistically significant. EQ5D score showed an improvement; with pre-op index average of 0.70. Post-op index average was 0.80. 11 patients were under 54 years old, 15 between 55–64, and 14 over 65. The greatest improvement was in the over 65s for MOxFQ and in the under 55s in EQ5D. 27/35 women showed improvement in all three MOxFQ domains, in contrast to all men. EQ5D also showed similar results. 65 patients filled out a PPE questionnaire. The results show overall average satisfaction of 72.9%. Conclusion. The overall data suggests that scarf+/− akin osteotomy procedures for hallux valgus are a success. Data suggests that higher success rates are found in those over 65 and male patients.

Tourniquet is widely used in orthopedic surgery to reduce intraoperative bleeding and improve visualization. We evaluated the effect of tourniquet application on both peri- and postoperative cefuroxime concentrations in subcutaneous tissue, skeletal muscle, calcaneal cancellous bone, and plasma. The primary endpoint was the time for which the free drug concentration of cefuroxime was maintained above the clinical breakpoint minimal inhibitory concentration (T>MIC) forStaphylococcus aureus (4 µg/mL). Ten patients scheduled for hallux valgus or hallux rigidus surgery were included. Microdialysis catheters were placed for sampling of cefuroxime concentrations bilaterally in subcutaneous tissue, skeletal muscle, and calcaneal cancellous bone. A tourniquet was applied on the thigh of the leg scheduled for surgery. Cefuroxime (1.5 g) was administered intravenously as a bolus 15 minutes prior to tourniquet inflation, followed by a second dose 6 hours later. The mean tourniquet duration (range) was 65 (58; 77) minutes. Dialysates and venous blood samples were collected for 12 hours. For cefuroxime the T>MIC (4 μg/mL) ranged between 4.8–5.4 hours across compartments, with similar results for the tourniquet and non-tourniquet leg. Comparable T>MIC and penetration ratios were found for the first and second dosing intervals. We concluded that administration of cefuroxime (1.5 g) 15 minutes prior to tourniquet inflation is safe in order to achieve tissue concentrations above 4 µg/mL throughout surgery. A tourniquet application time of approximately 1 hour did not affect the cefuroxime tissue penetration in the following dosing interval

The Cobb Stainsby forefoot arthroplasty for claw and hammer toes combines excision arthroplasty (Stainsby) with extensor tendon transfer to the metatarsal head (Cobb). We present a retrospective, three surgeon case series of 218 toes in 128 patients over four years. Clinical notes were reviewed for all patients and 77 could be contacted for a telephone survey. Follow up ranged from 12–82 months. All patients presented with pain and shoe wear problems from dislocated metatarsophalangeal joints either from arthritis, hallux valgus, Freiberg's disease or neurological disorders. Ipsilateral foot procedures were performed simultaneously in 24 (30%) patients. Seventy-two patients (94%) were satisfied, 72 (94%) reported pain relief, 55 (71%) were happy with toe control, 61 (79%) were pleased with cosmesis, 59 (77%) returned to normal footwear and 56 (73%) reported unlimited daily activities. Minor complications occurred in 17 (13%) and 3 (2%) developed complex regional pain syndrome. Four (5%) developed recurrent clawing. The Stainsby procedure permits relocation of the plantar plate under the metatarsal head for cushioned weight-bearing but can create a floppy, unsightly toe. By combining this with the Cobb procedure, our case series demonstrates improved outcomes from either procedure alone with benefits over alternatives such as the Weil's osteotomy.

Background and aims. Hallux rigidus in the metatarsophalangeal joint (MTPJ) can be treated with arthroplasty to reduce pain and enhance motion. Few studies have investigated the functionality and the survival of HemiCap arthroplasty. Primarily we aimed to examine the medium to long-term functionality and the degree of pain after surgery. Secondarily the failure and revision rate of HemiCap implants. Methods. A total of 106 patients were operated with HemiCap arthroplasty (n=114) from 2006 to 2014, median age 53 (16 to 80) years, 78 females, 37 dorsal flange (DF) implants. Patient charts were reviewed retrospectively to collect revision data. Pre operative Coughlin/Shurnas arthrosis degree, hallux valgus (HV), intermetatarsalintermetatarsal (IM) and Distal Metaphyseal Articular Angle (DMAA) angles was were measured. Pre- and post operative 3 weeks, 6 months, 1 and 2 year2-year pain levels of the first MTPJ by Visuel Analog Skala (VAS 1–10), American Orthopaedic Foot and Ankle Score (AOFAS 0 to 100 points) and, Range of Motion (ROM), were available for 51 patients. FortysevenForty-seven of the 70 available for reexamination partook in a cross sectional follow up where the Self-Reported Foot and Ankle Score (SEFAS 0–48 points) was added to the Patients Related Outcome Measures (PROMs). Statistics. Kaplan-Meier for survival analysis, adjusted for sex, radiological angles, degree of arthrosis and dorsal flange. Prospective PROMs and ROM compared by paired t-test. Results. At 3, 5 and 7 years we had an mean implant survival of 85%, 83% and 78%. Almost all were revised due to pain, one due to malalignment and one due to loosening of the Hemicap. Dorsal flange, gender, preoperative arthrosis degree, HV, IM or DMAA angles did not statistically influence the result. For those (n=23) that were re-examined, preoperative dorsal ROM changed from mean(sd) 21 (6) to 42 (18) degrees, VAS from 7 (2) to 2 (2) and AOFAS from 61 (11) to 87 (11) (p < 0.001). At mean 5 year follow up (n=47), mean (sd) dorsal ROM was 46 (17) degrees,. AOFAS was 84 (9), VAS 2 (1) and SEFAS 42 (6) points. The dorsal flange made no statistical significant difference for ROM or PROMs, but DF displayed 51 degrees of extension vs. 44 without (p=0.1). Periprostethic lucency (<2 mm) was observed in 27/47. Conclusions. In general, we saw an acceptable implant survival rate. We did not find any predictors that influenced implant failure and the design alterations with the dorsal flange are not evident clinically. Patients who were not revised had significantly less pain, greater ROM, and better overall foot and ankle conditions than preoperatively, but the data are biased by missing numbers and revisions

Introduction. The management of adolescent hallux valgus (AHV) remains controversial, with reservations about both conservative and surgical treatments. Non-operative management has a limited role in preventing progression. Surgical correction of AHV has, amongst other concerns, been associated with a high prevalence of recurrence of deformity after surgery. We conducted a systematic review to assess clinical and radiological outcomes following surgery for AHV. Methods & Materials. A comprehensive literature search was performed in the Cochrane Library, CINAHL, EMBASE, Google Scholar, and Pubmed. The study was performed in accordance with the recommendations of the PRISMA guidelines. Demographic data, radiographic parameters, and results of validated clinical scoring system were analysed. Results. Nine contemporary studies reporting on 201 osteotomies in 140 patients were included. The female to male ratio was 10:1. Mean age at operation was 14.5 years (10.5–22). Mean follow-up was 41.6 months (12–134). The mean post-operative AOFAS score was 85.8 (sd ±7.38). The mean AOFAS patient satisfaction showed that 86% (sd ± 11.27) of patients satisfied or very satisfied with their outcome. On the DuPont BRS, 90% rated their outcome as good or excellent. There was a statistically significant improvement in the IMA (p=0.0003), HVA (p<0.0001), and DMAA (p=0.019). The main complication was persistent pain (12%); others included infection (2%), scar hypersensitivity (4.5%), and non-union, metatarsalgia, and CRPS (each at 0.5%), and no reports of metatarsal head AVN. Conclusion. Based on the most current published evidence, surgery for AHV shows excellent clinical and radiological outcomes, with high patient satisfaction. The rates of recurrence and other complications are lower than the historically reported figures. There is, however, a need for high level, multi-centre collaborative studies with prospective data to establish the long-term outcomes and optimal surgical procedure(s)

Summary Statement. Objectifying postoperative recovery of patients with comminuted tibial plateau fractures treated with a unilateral plate trough the use of a gait analysis system. Introduction. Gait analysis has been a proved method for assessing postoperative results in patients with different orthopedic afflictions of the lower limb such as hallux valgus, ankle instabilities, knee osteoarthritis and arthroplasties but it has rarely been used for postoperative assessment of proximal tibial fractures. The more traditional means of quantifying postoperative articular step-off and limb axis deviations such as conventional X Rays and CT scanning and the clinician and patient completed scores that subjectively assess the outcome are complemented by the analysis of gait patterns set to objectify the most important patient related factor - the gait. As controversy exists in literature regarding the optimal treatment for severe tibial plateau fractures we proposed a gait study to evaluate locked angle unilateral plate osteosynthesis. Patient & Method: A computerised motion analysis system and a sensor platform were used to gather gait data from 15 patients with unilateral tibial plateau fractures graded Shatzker V and VI treated with a angular stable locked lateral plate osteosynthesis. Gait analysis was performed postoperatively based on patient availability and as soon as ambulation was possible and permitted without auxiliary support (crutches) at 4 (mean of 4,6), 6 (mean of 6,2) and 12 (mean of 11,7) months respectively, at a naturally comfortable walking. All patients were evaluated using classic anteroposterior and lateral knee radiography and were asked to fill the KOOS score questionnaire at the time of the gait analysis session. Results. The spatial-temporal and angular parameters revealed the expected postoperative decrease in ROM in both flexion and extension of the knee. Step and stance time objectively decreased between measuring session with an increase in single support of 3,7% mean value. A constant increase in walking speed was noted from a mean of 42 cm/sec (cadence of 31 st/min) at 4 months to a speed of 90 cm/sec (mean of 49 st/min cadence). We also determined a asymmetrical and wider walking base, increased area of support during single leg standing, decreased stance and increased swing phases for the injured knee compared to contralateral. Discussion. All patients in the study were subjectively satisfied with the results of the treatment, however we were able to detect quantifiable differences of gait parameters such between the injured and the contralateral knee such as step, stance and swing time and in knee flexion and adduction, combined with a modified, wider walking base. Ground reaction forces were strongly related to score improvement and thus directly reflected the healing at the fracture site

Cardiovascular disease is now the leading cause of morbidity and mortality worldwide. Raised blood pressures (BP) are associated with increased cardiovascular risks such as myocardial infarction, stroke and arteriosclerosis. During surgery the haemodynamic effects of stress are closely monitored and stabilised by the anaesthetist. Although there have been many studies assessing the effects of intraoperative stress on the patient, little is known about the impact on the surgeon. A prospective cohort study was carried out using an ambulatory blood pressure monitor to measure the BP and heart rates (HR) of three consultants and their respective trainees during hallux valgus, hip and knee arthroplasty surgery. Our principle aim was to assess the physiological effects of performing routine operations on the surgeon. We noted if there were any differences in the stress response of the lead surgeon, in comparison to when the same individual was assisting. In addition, we recorded the trainee's BP and HR when they were operating independently. The intraoperative measurements were compared with their baseline readings and their stress response, assessed using the Bruce protocol. Many trends were noted in this pilot study. All of the surgeons had higher BP and HR readings on operating days compared to baseline. The physiological parameters normalised by one hour post-theatre list in all subjects. When the trainer was leading the operation, their BP gradually increased until implant placement, while their trainees remained stable. On the other hand, when the trainee was operating and the trainer assisting, the trainer's BP peaked at the beginning of the procedure, and slowly declined as it progressed. The trainee's BP remained elevated throughout. The highest peaks for trainees were noted during independent operating. We conclude that all surgery is stressful, and that trainees are more likely to be killing themselves than their trainers

Objectives

Osteophytes are products of active endochondral and intramembranous ossification, and therefore could theoretically provide significant efficacy as bone grafts. In this study, we compared the bone mineralisation effectiveness of osteophytes and cancellous bone, including their effects on secretion of growth factors and anabolic effects on osteoblasts.
