ABSTRACT

BACKGROUND: Some children and adolescents can develop persistent pain and instability following inversion injuries of the ankle. In these cases, imaging exams could reveal small bone fragments distal to the lateral malleolus. For these patients, regular conservative treatment may not be successful, requiring additional management, which can include surgical treatment. This study aimed to present the short-to-midterm functional and clinical outcomes of a series of 12 pediatric and adolescent patients who underwent ligament repair surgery due to chronic instability associated with the presence of osseous components in the lateral ligaments. METHODS: A review of 12 patients treated with surgical ligament reconstruction of the ankle was evaluated. Clinical and functional evaluations were based on comparing the Visual Analogue Scale (VAS), AOFAS ankle-hindfoot score, and residual symptoms before and after the surgical intervention. RESULTS: Before the reconstructive approach, the mean VAS was 2.41 and the mean AOFAS score was 74.16. After the procedure, the standard VAS declined to zero, and the AOFAS score was 100 in all patients. The mean follow-up was 6.33 months. CONCLUSION: The surgical approach in children and adolescents with symptomatic ankle instability due to the presence of osseous fragments after an initial inversion trauma provided adequate clinical and functional results at short-to-midterm follow-up. LEVEL OF EVIDENCE: Level IV, retrospective case series.

ABSTRACT

INTRODUCTION: After an ankle sprain, up to 20% of patients may develop chronic lateral ankle instability (CLAI) requiring surgical treatment. The objective of this study was to investigate the functional outcomes and rates of return to sport activities in a cohort of non-athlete patients with chronic lateral ankle instability (CLAI) who underwent the opened Brostrom-Gould technique (BGT). MATERIALS AND METHODS: Seventy-nine patients (seventy-nine feet) from three different centers undergoing BGT were reviewed. For clinical and functional analysis, the AOFAS ankle-hindfoot scale was applied and rates of return to sport activities were assessed. Correlation of Δ-AOFAS and rates of return to sport activities with all variables analyzed was performed. RESULTS: Mean AOFAS score improved from 64.6 to 97.2 (p < 0.001). Sixty-one (77.2%) returned to preinjury activities and 18 (22.8%) changed to a lower-level modality. Symptoms of instability were related to Δ-AOFAS (p = 0.020). Change in the sport activity was related to pain and symptoms of instability (p = 0.41 and p < 0.001). CONCLUSION: Recreational athlete patients who underwent the BGT demonstrated excellent functional outcomes after a mean follow-up of 7 years. Residual pain and symptoms of instability after surgery were the main complaints associated with limitations in physical activities.

ABSTRACT

PURPOSE: Based on the tripod concept of load distribution, our study aimed to evaluate whether a slight extension of first metatarsal (M1) that may occur after the Lapidus procedure (LP) could alter the radiographic measurements of the hindfoot and influence clinical and functional outcomes. METHODS: Twenty-five patients (27 feet) were reviewed. Hindfoot radiographic analysis was based on seven measurements. Clinical and functional outcomes were evaluated with self-reported questionnaires. Transfer metatarsalgia was also assessed. Correlation analysis was performed according to variations of the studied variables. RESULTS: The average extension of the M1 was 4.26 degrees (p < 0.001). None of the hindfoot radiographic measurements changed significantly (p = 0.13, p = 0.50, p = 0.19, p = 0.70, p = 0.11, p = 0.36, p = 0.83). Patients improved on most questionnaires (p < 0.001). None presented transfer metatarsalgia. No correlation between M1 extension and clinical and functional outcomes was found. CONCLUSION: Possibly there is a tolerance of M1 extension in which it does not alter the radiographic measurements of the hindfoot, overload the lesser metatarsals, or compromise clinical and functional outcomes.

ABSTRACT

This study reports the clinical outcomes and evolution of 4 patients with subungual glomus tumor (GT) of the hallux treated with tumor excision. Preoperatively, all patients had pain of intensity 9 or 10. Three were sensitive to cold and had stabbing pain, and one reported pulsatile pain. No patient presented nail alterations. There were no bone alterations on radiographic images and diagnostic suspicion of GT was supported by magnetic resonance images. Surgical treatment was indicated due to severe pain and functional limitation. The GT excision was performed by removing the nail through an L-shaped incision in the nail bed. After surgery, they all showed clinical improvement with return to previous activities and had no difficulty in wearing regular shoes. Three patients were pain-free and one had occasional stabbing pain of intensity 2. Half of them had nail changes. There has been no recurrence so far. Thus, we found that resection of subungual GT of the hallux was effective for the clinical improvement of patients.Level of Evidence: IV, case reports.

ABSTRACT

PURPOSE: This study aimed to evaluate the effect of variations in bony and soft tissue foot widths on clinical and functional outcomes after hallux valgus correction with the Lapidus procedure. METHODS: Forty-three feet in 35 patients with a mean follow-up of 18.5 months undergoing the LP were reviewed. Clinical and functional data were assessed with the VAS for pain, AOFAS Scale, LEFS and SF-12 health survey, which is divided into physical and mental health composite scales (PCS-12 and MCS-12). Radiographic analysis of forefoot width was based on bony and soft tissue limits. Intermetatarsal-angle and HV-angle were also assessed. RESULTS: Bony width changed significantly from 95.5 mm to 84.2 mm (11.8%) and soft tissue width from 107.12 mm to 100.84 mm (5.86%) (p < 0.001). IMA and HVA improved significantly. Significant clinical and functional improvements were observed, except in MCS-12. In simple linear regression, correlation was found between variations of bony width with Δ-AOFAS and Δ-PCS-12, meaning that as the forefoot narrows, their values increase (p = 0.02 and p = 0.005, respectively). It was also related to Δ-IMA, meaning that the forefoot narrows as these parameters improve (p < 0.001 and p < 0.001). Soft tissue width was related to Δ-PCS-12 and Δ-AIM. In multiple linear regression, the strongest correlation was between bony width variation and Δ-IMA (p = 0.029, r2 = 0.22). CONCLUSION: Forefoot narrowing was correlated with improved clinical and functional outcomes, as measured by AOFAS and PCS-12. In addition, correction of the radiographic parameters, mainly IMA, reflected on a significant decrease in the forefoot width.

ABSTRACT

The modified Lapidus procedure (MLP), which consists of fusion between the first metatarsal (M1) and medial cuneiform, has been widely performed with satisfactory clinical outcomes, but it has a variable nonunion rate ranging between 4% and 10% and loss of correction in up to 5.8% of the cases. Excessive motion around the site of tarsometatarsal arthrodesis, specially at the intercuneiform joint, is probably the reason. The original Lapidus procedure (OLP), which includes fusion of the M1 to second metatarsal (M2), may be beneficial in preventing nonunion and recurrence. The objective of this study was to describe intraoperative technical tips in the OLP to improve M1 to M2 fusion, which may prevent complications. Since the Lapidus procedure continues to gain popularity, it is the authors opinion that the OLP requires special attention because it is a more technically demanding surgery compared to the MLP.Level of Evidence: Level V: Expert opinion.

ABSTRACT

Objective To evaluate the results obtained from the surgical treatment of malleolar ankle fractures associated with distal tibiofibular syndesmosis (DTFS) injury submitted to conventional surgical procedure for fracture fixation and DTFS fixation by suture button (SB). Methods Forty-nine patients were retrospectively evaluated, with a mean age of 45 years old and a mean follow-up of 34.1 months. Clinical and functional evaluation was based on the visual analogue scale (VAS) and on the American Foot and Ankle Society Score (AOFAS) for ankle and hindfoot, return to routine activities, and return to sport. Results The postoperative mean AOFAS and VAS were, respectively, 97.06 (confidence interval [CI 95%: 95.31-98.81] and 0.16 [CI 95% 0,04 - 0,29]. All patients returned to previous daily activities, and only 12 showed some residual symptom. There was no postoperative instability in any patient. Forty-six patients returned to sports activities and, of these, only 1 did not return to the level prior to the injury. Only two patients presented SB-related alterations. There was no report of dissatisfaction. Conclusion In malleolar fractures of the ankle with DTFS injury, the fixation of syndesmosis with SB demonstrated excellent postoperative results. Level of Evidence IV, retrospective case series.

ABSTRACT

INTRODUCTION: To present the short- to midterm clinical outcomes of a series of patients with isolated acute syndesmosis instability treated with arthroscopy and percutaneous suture-button fixation. MATERIALS AND METHODS: A review of 17 patients treated through the arthroscopic approach. The mean age of the patients was 27.8 years and the mean follow-up was 31.5 months. Clinical and functional evaluations were based on the VAS, AOFAS ankle-hindfoot score and time of return to preinjury level of activities. Imaging analysis was performed with stress radiographs, MRI and CT scan with stress. RESULTS: The average VAS was 0.5 and the mean AOFAS score was 95.5. Out of the 17 patients, 15 were able to return to their preinjury level of activities. The mean time of return to activities was 5.06 months. CONCLUSION: Arthroscopic approach and percutaneous suture-button fixation provided satisfactory clinical and functional results for selected patients with ASI at short- to midterm follow-up. LEVEL OF EVIDENCE: Level IV, retrospective case series.

ABSTRACT

The modified Lapidus procedure is considered a useful tool for correction of multiplanar deformities in the hallux valgus, including first metatarsal pronation. It offers a greater power of correction compared to most other osteotomies. However, postoperative complications can occur in up to 12% of cases. The aim of this study was to describe intraoperative technical tips in the management of the tarsometatarsal joint during multiplanar correction of severe hallux valgus deformity using the modified Lapidus procedure. It is not the authors' intention to describe a new technique, but to draw attention to intraoperative details in order to prevent complications as nonunion, extension of the first metatarsal and undercorrection of the deformity. Rotational correction of the first metatarsal with adequate bone coaptation of the first metatarsal and the medial cuneiform are the cornerstone for a satisfactory result.Levels of Evidence: Level V, expert opinion.

ABSTRACT

BACKGROUND: The objective of this study was to investigate functional results, the amount of time that patients missed from regular working activities, and the incidence of residual mechanical ankle instability following conservative treatment of a first episode of severe lateral ankle ligament sprain (with articular instability). METHODS: This prospective and randomized study included 186 patients with severe lateral ankle ligament injuries, who were randomly assigned into 2 conservative treatment groups. In group A, participants were treated with a walking boot with weight-bearing allowed, pain management, ice, and elevation with restricted joint mobilization for 3 weeks. In group B, patients were treated with a functional brace for 3 weeks. After this period, patients from both groups were placed in a short, functional brace for an additional 3 weeks, during which they also started a rehabilitation program. RESULTS: No statistically significant difference was found in pain intensity score between the 2 groups; however, functional evaluations based on the AOFAS ankle and hindfoot score system showed a statistically significant improvement in the group treated with the functional brace. In addition, the average recovery period necessary for patients of group B to resume their duties was shorter than that for patients in group A. No significant difference was detected in residual mechanical ankle instability between the 2 groups. CONCLUSION: Patients with severe lateral ankle ligament lesions treated with a functional brace were shown to exhibit somewhat better results than those treated with a walking boot, and both methods presented a very low incidence of residual chronic instability. We found adequate conservative treatment was sufficient to reestablish ankle stability and that functional treatment had a marginally better clinical short-term outcome with a shorter average recovery period. LEVEL OF EVIDENCE: Level I, prospective randomized study.

ABSTRACT

OBJECTIVE: This trial has the objective to investigate the incidence of mechanical ankle instability after the conservative treatment of first episode, severe ankle ligamentar lesions. This common lesion affects young, professional and physical active patients, causing important personal and economic consequences. There are difficulties related to adequate diagnosis and treatment for these lesions. METHOD: 186 patients with severe ankle ligament lesions were included in this trial. They were randomized in two treatment options. In group A patients were treated using ankle long orthoosis, weight bearing allowed as confortable, pain care, ice, elevation with restricted joint mobilization for three weeks. After that they were maintained in short, functional orthosis (air cast), starting the reabilitation program. In group B patients were immobilized using a functional orthosis (air cast), following the same other sequences that patients in group A. RESULTS: We did not find significant differences in relation to the residual mechanical ankle instability between both groups. We did not find differences in the intensity of pain, but the functional evaluation using AOFAS score system showed better results in the functional treatment group. CONCLUSION: The functional treatment (Group B) had better AOFAS score and few days off their professional activities, comparing with patients treated with rigid orthosis (Group A), without increased chance in developing ankle mechanical instability. .
