The modified Broström technique (MBT) is considered the reference standard for surgical management of ankle instability, with good short-term outcomes. However, limited evidence is available regarding outcomes for delayed presentations of instability. We report our outcomes for patients who underwent ligament repair using the MBT, from a single-surgeon retrospective study of consecutive patients. The minimum postoperative follow-up period was 6 months during a 5-year study period. The patients were retrospectively divided into 3 groups according to the delay in presentation: group 1, 6 months to 2 years; group 2, 2 to 4 years; and group 3, >4 years...

Distal metatarsal (MT) osteotomies have been used in mild or moderate cases of hallux valgus (HV) and proximal MT osteotomy has been considered the treatment of choice for severe deformities. A distal osteotomy could achieve a greater degree of correction by the addition of a distal soft-tissue procedure and be used to treat also severe deformity. Limited evidence about the use of the percutaneous subcapital osteotomy (SCOT); a type of MT osteotomy, in combination of a soft tissue procedure, is available. We evaluated this procedure routinely used in our clinic...

BACKGROUND: Identifying preoperative risk factors that may portend poorer operative outcomes remains a topic of current interest. In hip and knee arthroplasty patients, the presence of patient-reported allergies (PRAs) has been associated with worse pain and function after joint replacement. However, these results have not been replicated across studies, including in shoulder arthroplasty cases. The impact of PRAs on foot and ankle outcomes has yet to be studied. The purpose of our study was to evaluate whether PRAs influence patient-reported outcome in foot and ankle surgery...

BACKGROUND: Vancomycin is frequently applied locally to the operative site during foot and ankle procedures to help prevent infection. Although the efficacy of locally applied vancomycin has been demonstrated in spine surgery, there is no consensus on dosing and indication within foot and ankle surgery. Osteogenic differentiation of human mesenchymal stromal cells (hMSCs) is key to healing of both fractures and arthrodesis. The purpose of this research was to determine the impact of vancomycin on human hMSCs during the process of osteogenic differentiation...

BACKGROUND: The relationship between depressive symptoms and patient outcomes after hallux valgus surgery has not been well-studied. We hypothesized that patients with depressive symptoms would have greater subjective dysfunction preoperatively and less functional improvement and satisfaction after surgery when compared with patients without depressive symptoms. METHODS: A total of 239 adult patients who had surgical hallux valgus correction over a 2-year period were retrospectively enrolled...

BACKGROUND: A recent publication reported preoperative Patient-Reported Outcomes Measurement Instrumentation System (PROMIS) scores to be highly predictive in identifying patients who would and would not benefit from foot and ankle surgery. Their applicability to other patient populations is unknown. The aim of this study was to assess the validation and generalizability of previously published preoperative PROMIS physical function (PF) and pain interference (PI) threshold t scores as predictors of postoperative clinically meaningful improvement in foot and ankle patients from a geographically unique patient population...

BACKGROUND: We performed a prospective comparison of screws versus plate-and-screws for midfoot arthrodesis. MATERIALS: Between 2010 and 2015, a total of 50 patients with midfoot arthritis received screws or plate-and-screws for their midfoot arthrodesis. Function and pain were graded with the Foot and Ankle Ability Measures (FAAM) and visual analog scale (VAS), respectively. Data regarding arthrodesis healing and complications were recorded. RESULTS: Twenty-five patients received screws for fusion, where 21 achieved full arthrodesis healing by 6 months from surgery...

Posterior tibial tendon dysfunction (PTTD) is a common pathology of the foot and ankle. Numerous techniques are available to reconstruct the flatfoot. Fusions and tendon transfers are popular methods; however, a wide range of complications have been associated with these procedures. The objective of the present study was to demonstrate the outcomes of reconstructive surgery for flatfoot correction without tendon transfer or arthrodesis. We performed a retrospective study of 43 patients and 56 feet who had undergone flatfoot reconstructive surgery from November 2011 to June 2016, with a mean follow-up period of 60 weeks (range 12 to 60 months)...

BACKGROUND: Insufficient plantar flexor resistance due to plantar flexor weakness, an impairment common in patient populations, causes substantial gait deficits. The bending stiffness of passive-dynamic ankle-foot orthoses (PD-AFOs) has the capacity to replace lost plantar flexor resistance. Many patients who are prescribed PD-AFOs are older adults. While PD-AFO bending stiffness should be customized for patients, a method to objectively prescribe this stiffness does not exist. Quantifying natural plantar flexor resistance during non-pathological gait could provide a reference value for objectively prescribing PD-AFO bending stiffness...

REVIEW
P-L Docquier, P Maldaque, M Bouchard
Tarsal coalition is due to failure of segmentation between two or more foot bones during embryological development at a site where the joint cleft fails to develop. Depending on the nature of the tissue connecting the bones, the abnormality is a syndesmosis, synchondrosis, or synostosis. Although the coalition exists at birth, synostosis usually develops only late during growth. Talo-calcaneal and calcaneo-navicular coalitions account for over 90% of all cases of tarsal coalition. The joint at the site of the coalition is stiff...

Charcot neuroarthropathy is a destructive process that occurs in patients with peripheral neuropathy, often due to poorly controlled diabetes mellitus. Surgical reconstruction can be necessary to provide a plantigrade foot that is wound free. A risk of major amputation exists after a Charcot event and after attempted reconstruction. We retrospectively reviewed the data from 34 patients (36 reconstructions) who had undergone reconstructive surgery for Charcot neuroarthropathy. The mean patient age was 56.44 years...

BACKGROUND: Idiopathic toe walking is a diagnosis of exclusion characterized by a persistent toe-toe gait pattern after three years of age. Treatment for toe walking includes physical therapy, orthotics, casting, Botulinum Toxin A injection into gastrocnemius/soleus muscles, and/or surgery; yet, little evidence exists regarding long-term treatment effects. RESEARCH QUESTION: The objective of this study was to explore the differences in longer-term gait outcomes and severity of idiopathic toe walking between children treated actively with casting or inactively following recommendations for stretching...
