Comparing Outcomes of Acute Versus Gradual Surgical Correction in Brachymetatarsia.

Brachymetatarsia consists of a shortened metatarsal resulting in a shorter toe. Pain with shoe wear and cosmetic concerns are the main reasons for surgical intervention. Surgical techniques to increase metatarsal length include acute lengthening with interpositional bone grafting or gradual lengthening with callus distraction. We performed a retrospective cohort study for 1 surgeon's patients at 1 institution over 10 years. Twenty-nine feet in 22 patients met inclusion criteria for acute correction; 16 feet in 11 patients were included for gradual correction. Mean ages were 26.3 ± 12.1 and 27 ± 10.8 in the acute and gradual groups, respectively (p = .79). Most patients were female: 95.4% of acute cases and 90.1% of gradual cases. Most involved lengthening the fourth metatarsal: 86.7% and 100% of acute and gradual groups, respectively (p = .54). Correction obtained amounted to 14.4 ± 2.97 mm (range, 10-22 mm) in acute cases and 14.8 ± 2.39 mm (range, 10-20 mm) in gradual cases (p = .81). The mean percent increase in metatarsal length was 21.1 ± 14% for acute and 22.6 ± 12.4% for gradual (p = .72). Mean consolidation was 8.9 ± 2.51 weeks for acute and 21.4 ± 10.8 weeks for gradual (p = <.001). Nonunions were most common in the gradual group (37.5%) with need for more revisional surgery (43.5%) compared with the acute group; both were statistically significant. We conclude that acute brachymetatarsia correction can obtain correction similar to the gradual technique with fewer postoperative complications and less osseous consolidation time.

The Prevalence of Bunions in the Setting of Brachymetatarsia.

Brachymetatarsia is caused by premature closure of the physis and is characterized by a short metatarsal. Additional foot conditions may exist in patients presenting with brachymetatarsia, such as hallux valgus (HV). A retrospective study was performed to evaluate the prevalence of HV and brachymetatarsia in the ipsilateral foot. Ninety-seven feet with congenital brachymetatarsia were reviewed in a multi-study cohort of 66 patients who underwent surgical correction between January 2005 and August 2020 at a single institution. The group was comprised of 61 females and 5 males, with a mean age of 27 years. HV deformities were verified with standardized anteroposterior radiographs. HV was present in 29 of 97 feet for a prevalence of 30% in the feet with brachymetatarsia. Our results demonstrate a 30% prevalence of HV associated with brachymetatarsia. This information is helpful for foot and ankle surgeons managing brachymetatarsia to determine appropriate conservative or surgical management of this condition.

The Role of the Shortened Proximal Phalanx in the Setting of Brachymetatarsia.

Brachymetatarsia is a condition in which a metatarsal bone does not grow out to full length. This is caused by premature physeal closure. The proximal phalanx associated with the shortened metatarsal helps achieve the natural parabola of the foot. A hypoplastic proximal phalanx is a common finding in patients with brachymetatarsia. The goal of this study was to determine the length of the proximal phalanx in the setting of brachymetatarsia, and how much the shortening is attributed to the clinically smaller toe. We performed a retrospective study to evaluate the length of the proximal phalanx in the shortened ray. After the metatarsal was brought out to the desired length of correction, the proximal phalanx was measured on radiographs. Ninety-seven feet with congenital brachymetatarsia were reviewed in a cohort of 66 patients who underwent surgical correction between January 2005 and February 2020 at a single institution. The group was comprised of 61 females and 5 males, with a mean age of 27.5 years. The average length of the proximal phalanx associated with the affected metatarsal was noted to be 18.9 ± 3.83 mm for males and 15.6 ± 4.02 mm for females. Our results indicate the shortened proximal phalanx is 5 mm shorter when compared to normal population and is a contributing factor to the shortened clinical appearance of the digit in brachymetatarsia. Treating surgeons should be aware of this to better educate patients on the influence of the digit on the overall shortening seen in cases of brachymetatarsia.

Surgical Optimization for Charcot Patients.

Reconstruction of the Charcot foot and ankle demonstrates significant challenges to the foot and ankle surgeon. At present, there is limited clear consensus on the best approach for preoperative optimization. The primary aim of Charcot reconstructions is to limit the risk of ulceration by providing a stable plantigrade foot allowing ambulation. The focus of this article is the discussion of modifiable risk factors associated with Charcot reconstruction for preoperative optimization.

Tibial Lengthening and Intramedullary Nail Fixation for Hindfoot Charcot Neuroarthropathy.

Hindfoot and ankle Charcot neuroarthropathy is a challenging condition to treat, specifically with segmental bone defects secondary to avascular necrosis or infection. Several techniques exist alongside continued challenges of nonunion and complication rates. The authors assert that combining distal tibial distraction osteogenesis with external fixation in tibiocalcaneal or tibiotalocalcaneal arthrodesis should be considered an effective method for management of complex Charcot neuroarthropathy conditions of the ankle. This staged procedure technique resulted in a high rate of union in patients who are often considered a high risk for nonunion, as well as eradication of infection, minimal soft tissue disruption, and improvement in limb length.

Increased Arthrodesis Rates in Charcot Neuroarthropathy Utilizing Distal Tibial Distraction Osteogenesis Principles.

Charcot neuroarthropathy of the hindfoot and ankle poses substantial challenges due to deformity, segmental bone loss, chronic infection, and difficulty with bracing. Hindfoot or ankle arthrodesis is often employed at high rates of complications and nonunion. This study reports 15 consecutive patients with Charcot neuroarthropathy who underwent tibiotalocalcaneal or tibiocalcaneal fusion with simultaneous distal tibial distraction osteogenesis with a mean follow-up period of 20.2 ± 5.66 months. Arthrodesis rate was 93.3% (14 patients) with mean time to fusion of 4.75 ± 3.4 months. One hypertrophic nonunion occurred at the arthrodesis site. Complete consolidation of 4 cortices was achieved at the distraction site in 93.3% of patients (14 patients) with a mean duration to consolidation of 9.8 ± 3.3 months. One patient experienced hypertrophic nonunion at the regeneration site. The authors report a technique to enhance arthrodesis rates in Charcot neuroarthropathy by combining distal tibial distraction osteogenesis with simultaneous tibiotalocalcaneal or tibiocalcaneal arthrodesis for hindfoot fusion and salvage. Distraction osteogenesis supports enhanced vascularity to the arthrodesis site.Level of Clinical Evidence: Level 4.

Management of Osseous Defects in the Tibia: Utilization of External Fixation, Distraction Osteogenesis, and Bone Transport.

The use of external fixators for distraction osteogenesis has revolutionized treatment options for segmental bone defects in the tibia. Following corticotomy, the latency phase allows the biologic environment to initiate healing, and optimized distraction rates produce regenerate. Regenerate consolidation can be improved with local and systemic biologic optimization. Consolidation time is often considered to be 3 to 4 times longer than distraction in adults. Soft tissue considerations are important during external fixation and distraction. Additionally, slow regenerate can be benefited by various techniques discussed in this article. Distraction osteogenesis is a beneficial tool for segmental bone defects.

Behcet's DiseaseA Case Report.

Behcet's disease is a rare autoimmune systemic vasculitis. It usually presents with a symptom complex involving primarily mucocutaneous lesions, genital lesions, and uveitis. When it involves the lower extremity, venous and arterial disease predominates, and joint involvement occurs in approximately 50% of patients. We present a patient with Behcet's disease who was initially referred to us for chronic toenail pathology.

Evaluation of Fixation Techniques for Metatarsocuneiform Arthrodesis.

First metatarsocuneiform joint arthrodesis has been used in foot and ankle surgery for the treatment of hallux abductovalgus deformity, among other pedal pathologic entities. The goal of the present retrospective study was to compare the fusion rates and complications of an intraplate compression screw fixation, crossing solid core screw fixation, and a single interfragmentary screw with a simple locking plate. All procedures were performed by a single surgeon, and all patients received an identical postoperative protocol. A medical record review was performed of 147 evenly distributed surgical methods. All patients were non-weightbearing by protocol for 4 weeks. The patient covariates included sex, age, nicotine status, osteoporosis, and diabetes. These variables were balanced among the treatment groups and were noncontributory, with the exception of sex. Male patients had a 6 times greater odds of experiencing nonunion. The overall nonunion rate was 6.7%, with 4% symptomatic and requiring revision. The individual nonunion rates for each method were 2% for intraplate compression screw fixation, 5% for single interfragmentary screw with locking plate fixation, and 9% for crossing solid core screw fixation. None of the differences reached statistical significance. The corresponding hardware removal rates were 12%, 11%, and 0%.

Relationship Between Academic Performance and Student Self-Assessment of Clinical Performance in the College of Podiatric Medicine and Surgery.

BACKGROUND: Student self-assessment is viewed as an important tool in medical education. We sought to identify the relationship between student academic performance and third-year clinical performance self-assessment. No such study exists in podiatric medical education. METHODS: Third-year podiatric medical students from the classes of 2012 through 2014 completed a self-assessment of their performance for each of five broad clinical podiatric medical domains (Professionalism, Medicine, Radiology, Surgery, and Biomechanics/Orthopedics). The assessment was completed after students finished the first 12 weeks of their third-year clinical rotations (PRE) and a second time at the conclusion of the third year (POST). The mean self-assessment score for PRE and POST surveys for all combined domains was determined for each student. This mean was compared with the student's 3-year cumulative grade point average (GPA). Students' clinical experiences for the year were essentially identical. RESULTS: No statistically significant correlation was identified between cumulative GPA and the PRE and POST clinical self-assessments or with the change between PRE and POST assessments based on the Pearson correlation test for each class separately or on the pooled data. CONCLUSIONS: Published studies in allopathic medical education have shown that students with lower GPAs tend to rate their clinical performance higher in initial clinical performance self-assessment. Our results show that student academic performance was not correlated with clinical performance self-assessment. These findings may be due to the explicit description of successful clinical competency completion, the orientation students receive before the start of clinical training, and the continuous feedback received from clinical preceptors.
