RESUMO
BACKGROUND: Lateral hallucal sesamoidectomy is an infrequently performed procedure indicated for patients with sesamoid pathology failing conservative treatment. Concerns exists regarding patient satisfaction, plantar scar pain, hallux malalignment and metatarsophalangeal joint (MTPJ) movement restriction following sesamoidectomy. This study aims to assess patient satisfaction after lateral hallucal sesamoidectomy via the plantar approach. METHODS: In this retropective study with prospective follow-up, all patients who underwent lateral hallucal sesamoidectomy between January 2004 and December 2017 were reviewed. Twelve patients (14ft.) were available for final assessment. Outcome measures were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) clinical rating scale and the Self-Reported Foot and Ankle questionnaire (SEFAS). Patients were assessed clinically and radiologically. The average postoperative follow-up was 111.5 months (range 28-177 months). RESULTS: All patients reported excellent outcome scores with a mean SEFAS score of 46.08 (range 43-48) and a mean AOFAS score of 92.33 (range 78-100) at final follow-up. All twelve patients reported their outcome as being excellent. No malalignment was noted clinically, however, three patients had a noticeable increase in the gap between the hallux and second toe when compared to the contralateral side. Range of motion at the MTPJ was preserved with a mean dorsiflexion of 80.83° (range 70-90°) and a mean plantarflexion was 25.83° (range 0-30°). None of the patients experienced any pain, discomfort or irritation related to the plantar scar. One patient developed neuroma like symptoms in the first web space. CONCLUSION: Lateral hallucal sesamoidectomy via a plantar approach is an effective and reliable treatment option as demonstrated by the high levels of patient satisfaction, preservation of function, excellent PROM scores and limited complications in this study. LEVEL OF EVIDENCE: Level 4.

BACKGROUND: Ten percent of patients with a deep-vein thrombosis (DVT) will develop a fatal pulmonary embolism (PE), often initially asymptomatic. The risks and benefits of pharmacological thromboprophylaxis are well documented in respect of total joint arthroplasty and hip fractures, but little is understood about the incidence of venous thromboembolism (VTE) or the potential risks and benefits of chemoprophylaxis in foot and ankle surgery. OBJECTIVE: To determine whether prophylactic chemoprophylaxis had any impact on the prevention of VTE in a cohort of foot and ankle surgical patients requiring the combination of below-knee cast immobilisation and non-weightbearing for ≥4 weeks. METHODS: Between March 2014 and April 2015, a prospective cohort study of 142 patients was performed. All completed a thrombosis risk assessment form prior to surgery and were commenced on rivaroxaban (Xarelto) 10 mg/d postoperatively. The primary outcome measure was clinical VTE confirmed by compression ultrasonography (DVT) or a ventilation/perfusion scan (PE). RESULTS: Three patients (2.1%) developed a clinical DVT. Two did so well beyond the immobilisation and anticoagulation period, and one was non-compliant with therapy. The average risk factor score in this subgroup was 7. No patient had a DVT while on the prescribed regimen of anticoagulant therapy. Five patients (3.5%) developed wound breakdown, two requiring surgical debridement with local skin flap closure. One case of menorrhagia that may have been linked to the anticoagulant therapy was reported. When compared with a previous study, pharmacological thromboprophylaxis significantly reduced VTE risk (p=0.02). CONCLUSIONS: Oral pharmacological thromboprophylaxis significantly reduces the risk of VTE in patients requiring cast immobilisation and non-weightbearing following foot and ankle surgery. The risk/benefit ratio favours this treatment as opposed to the treatment of major morbidity following non-fatal VTE.
RESUMO
BACKGROUND: Low-molecular-weight heparin and vitamin K antagonists such as warfarin are the gold standard for prohylaxis and treatment of venous thromboembolic disease (VTED). Direct oral anticoagulants (DOACs) result in predictable anticoagulation with significantly reduced inter- and intra-patient variability. DOAC absorption is rapid, with a short half-life and relatively few drug interactions. DOACs are effective and safe at fixed doses without activity monitoring. However, specific situations may require assessment of accurate drug activity. Rivaroxaban, a DOAC targeting activated coagulation factor X (FXa), is registered for the prevention and treatment of VTED in South Africa. OBJECTIVES: To establish a prophylactic rivaroxaban activity level range and determine any associations with clinical complications, viz. haemorrhage and/or thrombosis. METHODS: Samples from 115 orthopaedic patients were tested 3 hours after a prophylactic oral dose of 10 mg rivaroxaban with STAGO rivaroxaban anti-FXa reagent on an automated coagulation analyser. Patient demographics and clinical outcomes were documented. RESULTS: The mean rivaroxaban anti-FXa level was 105.7 ng/mL. Two patients developed adverse events on therapy. One patient had minor bleeding (menorrhagia) (drug activity level 288.7 ng/mL) and another a deep-vein thrombosis (drug activity level 34.7 ng/mL). Statistical analysis demonstrated an association between drug activity and advancing age (p=0.008), most apparent among those aged ≥65 years. CONCLUSIONS: Measuring rivaroxaban activity levels reduces uncertainty if treatment failure and complications occur. Patients aged ≥65 years should be closely monitored. A local rivaroxaban activity level for patients on rivaroxaban prophylaxis has been established.
