A Prospective Evaluation for a Possible Safe Skin Bridge in Elective Foot Surgery.

Background: In foot and ankle surgery, adequate surgical exposure often requires multiple incisions to be used near one another, thus creating a skin bridge. As the skin bridge becomes narrower, the wound edge vitality is potentially compromised and therefore the wound's ability to heal. The impact of local, host, and surgical factors on wound healing are well documented in the literature; however, little is known about the role of the skin bridge.

Outcomes of Total Ankle Arthroplasty After Periprosthetic Cyst Curettage and Bone Grafting.

Total ankle arthroplasty (TAA) has become a popular management option for ankle arthritis. Periprosthetic osteolysis is one of the most common causes for reoperation in TAA. A CT scan should be done in all suspected osteolysis cases to confirm location, quantify size and aid in surgical planning.

The use of a 3D printed titanium implant for arthrodesis in the management of large osseous defects in the ankle.

Background: Large osseous defects (LOD) in the ankle occur because of multiple aetiologies. Advancement in 3-dimensional (3D) printing technologies has led to the use of custom implants and instrumentation their management. A 3D printed patient-specific porous titanium cage which allows for peripheral osteo-integration and autogenous bone-grafting could be an ideal implant in these cases.

Foot and Ankle Injuries in Elite South African Cricketers: A Descriptive Analysis of Injury Surveillance Data.

Introduction: Injury surveillance is an important part of injury risk reduction in the sporting population. This study describes the type, side (dominant or non-dominant), occurrence, impact, activity of onset, and severity of foot and ankle injuries in elite South African male and female cricketers.

Methods: Foot and ankle injuries sustained by elite cricket players between 2018 and 2021, obtained from the records of Cricket South Africa, were descriptively analysed.

Tumor induced osteomalacia from a peripheral mesenchymal tumour of the foot.

Tumour induced osteomalacia (TIO) is a rare condition caused by peripheral mesenchymal tumours (PMT) which produce fibroblast-growth factor 23 (FGF23). FGF23 inhibits renal phosphate reabsorption leading to vitamin D resistant osteomalacia. The rarity of the condition and difficulty with isolating the PMT make diagnosis difficult, with delayed treatment leading to significant patient morbidity.

Patient reported outcomes following revision neurectomy through a dorsal approach for recurrent interdigital neuroma.

Interdigital neuroma is one of the commonest causes of metatarsalgia. The reported success rate after excision of a primary neuroma is 74%. Recurrent symptoms after neurectomy can be due to a recurrent interdigital neuroma.

A Rare Case of Flexor Digitorum Accessorius Longus Muscle Presenting as Tarsal Tunnel Syndrome.

Tarsal tunnel syndrome (TTS) is a relatively uncommon nerve entrapment neuropathy. Many pathologies are reported as possible causes for TTS. The diagnosis of TTS can be difficult and often missed.

Comparison of 2 Oblique Fifth Metatarsal Osteotomies for the Management of a Bunionette.

Background: A bunionette is a painful prominence of the fifth metatarsal head. This study aimed to compare the clinical outcome of 2 corrective osteotomies, namely, the Mau-type and Ludloff-type osteotomies. We report results with regard to correction, healing, complications, and patient-reported outcomes.

CT Scan Assessment and Functional Outcome of Periprosthetic Bone Grafting After Total Ankle Arthroplasty at Medium-term Follow-up.

Background: Periprosthetic cysts can occur in up to 95% of total ankle arthroplasties (TAA) and have been correlated with implant failure. The aim of this study was to determine the clinical and radiologic outcomes, using computed tomographic (CT) scan, after periprosthetic cyst bone grafting and assess for the minimum cyst size that should be grafted.

Methods: A retrospective review was performed of all TAA procedures performed between 2007 and 2014 (n=93).

Knee scooter related injuries and satisfaction in patients following foot and ankle surgery.

Background: Knee scooters have become popular amongst foot and ankle surgeons for patients who are required to be non-weight bearing. Information is limited regarding falls and injuries sustained while using a knee scooter and potential contraindications to their use are ill-defined. No study has assessed patient reported injuries and satisfaction.

First webspace Morton's neuroma case report with literature review.

Morton's neuromas are benign lesions of the inter-digital nerves within the foot. They are most commonly found in the second and third webspace. Morton's neuroma of the first webspace is very rare.

Reliability of the Radiographic Measurement of the Hallux Interphalangeal Angle.

Background: The hallux valgus interphalangeus (HVI) deformity has a common association with hallux valgus and hallux rigidus. The HVI is formed by the angle between the long axes of the proximal and distal phalanges. The normal value for this angular deformity in the coronal plane is less than 10°.

Radiographic Assessment of Relative First Metatarsal Length Following Modified Lapidus Procedure.

Background: The modified Lapidus is a surgical procedure for managing moderate to severe hallux valgus, especially in the presence of first tarsometatarsal joint arthritis or hypermobility. It has good long-term results but reportedly can lead to transfer metatarsalgia due to inherent shortening of the first metatarsal.

Methods: A retrospective analysis of all adult patients who underwent a modified Lapidus procedure during a 3-year period was performed.

Outcomes of bilateral simultaneous hallux MTPJ fusion.

Background: Arthrodesis of the first metatarsophalangeal joint (MTPJ) is a frequently performed surgical procedure. Many patients have bilateral hallux MTPJ pathology requiring bilateral arthrodesis. There are concerns that bilateral simultaneous hallux surgery, under one anaesthetic, results in the patient being severely incapacitated in the early post-operative period.

Functional and patient reported outcomes following lateral hallucal sesamoidectomy.

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.

Morphology of the first metatarsal head as a risk factor for hallux valgus interphalangeus.

Background: The aetiology of hallux valgus interphalangeus (HVI) is not well understood. First metatarsophalangeal joint stability, influenced by first metatarsal head shape, may be linked to HVI. We hypothesised that first metatarsal head shape is a risk factor for HVI.

Association Between Plantar Fasciitis and Isolated Gastrocnemius Tightness.

Background: An association between plantar fasciitis and isolated gastrocnemius tightness (IGT) has been postulated in the literature; however, there have been few studies to prove this relationship. This prospective cross-sectional cohort study was aimed at determining the association between plantar fasciitis and IGT.

Methods: Three groups comprising 45 patients with plantar fasciitis (group 1), 117 patients with foot and ankle pathology other than plantar fasciitis (group 2), and 61 patients without foot and ankle pathology (group 3) were examined for the presence of IGT using the Silfverskiöld test.

A prospective 24 months follow-up of a three component press-fit prosthesis for hallux rigidus.

Background: The aim of this study was to evaluate the results following total first metatarsophalangeal (FMTP) joint replacement arthroplasty using a modular three component press fit prosthesis at two year follow up.

Methods: All patient data was collected in a prospective way in four study centres. Both preoperative and postoperative evaluation consisted of an assessment using the AOFAS-HMI score, visual analogue scale for pain, evaluation of the range of motion and patient satisfaction scores.

Schwannoma and neurofibroma of the posterior tibial nerve presenting as tarsal tunnel syndrome: review of the literature with two case reports.

We present two case reports of peripheral nerve tumors (schwannoma and neurofibroma) that presented as tarsal tunnel syndrome for many years. There has never been a report of multiple neurofibroma of the posterior tibial nerve presenting as a tarsal tunnel syndrome. Both patients were treated surgically with good outcomes.

The benefit of pharmacological venous thromboprophylaxis in foot and ankle surgery.

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.

Tibialis Posterior Tendon Dislocation: A Review and Suggested Classification.

Tibialis posterior tendon dislocation is a rarely described entity that is easily missed, resulting in delayed diagnosis and treatment. A review of the English published data on the topic showed inconsistency in the reporting of injuries and surgical management techniques, leading us to describe a novel classification system to guide treatment and future reporting. We also describe a case of tibialis posterior tendon dislocation in a professional volleyball player and our surgical technique for correction, including retromalleolar groove deepening.

Use of locking barbed sutures in foot and ankle surgery. A case series.

Background: Barbed sutures represent a novel technique for wound closure. By distributing tension forces across the length of a wound, it results in better wound healing. A recent article from Chowdhry et al.
