Chevron Osteotomy

Numerous procedures have been described for the surgical treatment of symptomatic bunionettes. We describe the technique, results, and follow-up of patients treated with a chevron osteotomy of the distal fifth metatarsal. This surgical approach to the treatment of bunionette is presented as a viable alternative to other surgical procedures. Sixteen distal fifth metatarsal chevron osteotomies were performed on 12 patients. Follow-up was from 15 months to 6 years, with an average follow-up of 3.2 years. A 100-point scoring system was devised and the average score improved from 44 points before surgery (range 20–65) to 91 points after surgery (range 65–100). There was one complication of a transfer metatarsalgia. The overall results were good to excellent, except for the transfer metatarsalgia, which was rated as fair. We have used the procedure in a laterally deviated, plantar metatarsal. There is concern that alternatives be used in a laterally deviated, plantarflexed fifth metatarsal. We have continued to use the chevron osteotomy with this condition.

Results of biplanar chevron osteotomy performed on patients with mild-to-moderate hallux valgus deformity with an increased distal metatarsal articular angle (DMAA) are shown. The study included clinical data of 32 patients (54 feet) who had completed a 2-year follow-up, and radiological data of these 32 and other 29 patients (50 feet) for a total of 61 patients (104 feet, 53 right and 51 left). There were 59 females and two males with ages varying from 11 to 66 years. According to the AOFAS Hallux Rating, the preoperative average score (50) improved to 90 (average score after the surgery). The hallux valgus angle was improved from an average of 25° to 14°, the first intermetatarsal angle from 12° to 8° and the DMAA from 15° to 5°. At the end of treatment, 94% of patients were classified as having grade 0 or I sesamoid lateral sub-luxation. Given improvement in angles and 90% of patients satisfied with an average AOFAS postoperative score of 90, the technique seems indicated for treatment of symptomatic hallux valgus deformity with increased DMAA.

Severe Hallux Valgus

Introduction: Hallux valgus is a multifactorial disease, and heredity is the main associated factor. Pain and discomfort when using closed-toed shoes occur in many cases, adversely affecting quality of life. Surgical treatment is indicated when pain and disability persist after conservative treatment. Currently, more than 150 surgical techniques are described for hallux valgus correction, with no consensus regarding the best treatment. With the advent of minimally invasive techniques for hallux valgus correction, Vernois developed the percutaneous chevron osteotomy. This technique allows up to 100% lateral translation of the contact area of the osteotomy. Objective: the objective of the present study was to assess the correction of radiographic parameters, clinical improvement and potential complications of the first 30 cases of moderate and severe hallux valgus operated on at our hospital using the percutaneous chevron technique. Methods: A total of 26 patients (30 feet) underwent surgery. The following parameters were measured in the pre- and postoperative periods: the first metatarsophalangeal (MTP) angle, the intermetatarsal angle between the 1st and 2nd metatarsals (IMA), the distal metatarsal articular angle (DMAA) and the pre- and postoperative American Orthopedic Foot and Ankle Society (AOFAS) scores, with a minimum follow-up period of 6 months. Results: The mean age of the patients was 52.3 years. During the preoperative period, the mean AOFAS score was 45.6; it increased to 90.3 after the procedure, indicating a statistically significant improvement. The mean MTP angle, IMA and DMAA were 29.7°, 14.2° and 14.2° before surgery and 12.8°, 8.2° and 11.1° after surgery, respectively. The improvements in the MTP angle and the IMA were also significant. There was no decrease in angles or worsening of AOFAS scores during follow-up. Conclusion: The percutaneous chevron technique was safe and effective for correcting cases of moderate and severe hallux valgus, with significant improvements in clinical and radiological parameters and a low rate of postoperative complications.

Abstract Introduction Nonunion of the distal radius is an extremely rare and serious complication with unpredictable outcomes. The aim of the present study is to analyze the radiological and functional results after a protocolized surgical treatment. Material and Methods A retrospective review of case series of patients with diagnosis of nonunion of the distal radius surgically treated from 2010 to 2016. The diagnosis of nonunion was made at 6 months without signs of consolidation. According to computed tomography (CT) scan images, we propose a classification of this complication as type I: no deformity or mild deformity, with subchondral metaphyseal bone stock beneath lunate facet greater than 10 mm, with no degenerative changes at the distal radioulnar joint (DRUJ); type II: moderate deformity or degenerative changes in the DRUJ, distinguishing between IIA and IIB based on the subchondral metaphyseal bone stock; and type III: degenerative changes at the midcarpal joint. In all cases, a reconstructive technique consisting of volar locking plate osteosynthesis with autologous tailored iliac crest graft was performed, hence none of the cases were classified as type III. Results In total, six cases were included. Mean follow-up: 58 months (range: 30–108 months). Consolidation was achieved in a mean period of 5 months (range: 3–9 months). Average active range of motion: flexion: 54° (range: 10°–80°); extension: 40° (range: 10°–85°); supination: 82.5° (range: 75°–85°); pronation 80° (range: 55–85°); radial deviation: 15° (range: 5°–20°); and ulnar deviation 15° (range: 5–20°). Mean strength: 24.15 Kg (6.9–35 Kg). The average score on the Visual Analog Scale (VAS) at rest was of 0.6 (0–2), and with movement, it was of 1.8 (0–4). The mean postoperative score on the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire was of 18.48 (range: 0–50.8). Average radial height: 9.65 mm (range: 7–12 mm); average radial angulation: 17° (10°–20°); volar tilt: 8.36° (range: 0.2°–21°); average ulnar variance: 1.52 mm (range: 0–3.5 mm). Complications: persistent nonunion, superficial wound infection, acquired residual ulnar club hand deformity, radiocarpal arthritis, and midcarpal arthritis. Nevertheless, no salvage techniques were needed or requested during the follow-up, with all patients in an active work situation or living an active life in complete normality. Conclusions The protocolized surgical treatment of pseudoarthrosis of the the distal radius, based on our proposed classification, offers good functional outcomes in the long-term follow-up.

Insulinomas, although rare, are the most common pancreatic functioning neuroendocrine tumors. The diagnostic workup is commonly made late in time and surgical treatment is the only curative method. Our aim was to analyze the surgical approach to pancreatic insulinomas, through a 15-year series of patients who underwent surgery for this matter. From January 2006 to December 2020, we performed a retrospective review of the medical records of all the patients who underwent surgical treatment for insulinoma. Fourteen patients with insulinoma performed surgical intervention, 78,6% were of the female gender and the mean age was 48 years (19-86 years). Four (28,6%) of the tumors were located in the head of the pancreas, 5 (35,7%) in the body and 5 (35,7%) in the tail. Complications occurred in 4 patients (28,6%) following surgery. On follow-up, there was one (7,1%) case of local recurrence, thus necessitating a new surgical intervention [1-8].

From 1986 to 1990, 42 feet in 30 patients had a combined chevron osteotomy and lateral release to correct their painful bunion deformity. Seventeen patients, 23 feet, were available for follow-up. The purpose of this study was to evaluate the outcome of this procedure and to determine the incidence of avascular necrosis. The patients were examined by an independent examiner, radiographs obtained, and questionnaires filled out. Avascular necrosis was determined using plain films read by a musculoskeletal radiologist who did not know the outcomes. The average age was 45 years at the time of the procedure. Average follow-up was 50 months. The preoperative intermetatarsal angle averaged 13° and the hallux valgus angle averaged 31°. At study follow-up, the intermetatarsal angle averaged 8° and the hallux valgus angle averaged 17.5°. The results were graded by the Mayo Clinic Forefoot Scoring System (75-point scale) and a subjective scoring system. Average postoperative Mayo Clinic score was 67. Fifteen feet were subjectively rated as excellent, six as good, and two as fair. Complications occurred in four feet. Hallux varus occurred in two feet, extension contracture in one foot, and an infection in one foot. None of the feet developed definite radiographic evidence of avascular necrosis. Distal chevron osteotomy combined with a lateral release for corrective bunion surgery has come under scrutiny, because of the risk of avascular necrosis of the first metatarsal head. However, our study showed no evidence of avascular necrosis on radiographs. In addition, 91% of patients had good to excellent results at an average 50-month follow-up.

Background: In this study, we aimed to evaluate the success of surgery and a complete resection for bronchiectasis treatment and to present our 23 years of surgical experience. Methods: Between January 1991 and December 2013, a total of 1,357 patients (667 males, 690 females; mean age 30.5±14.3 years; range, 3 to 73 years) with the diagnosis of bronchiectasis who underwent pulmonary resection in our clinic were retrospectively analyzed. Demographic and clinical characteristics of the patients, etiologies, symptoms, localizations, surgical procedures, and long-term follow-up results were evaluated. Results: There were 1,394 surgeries, as 37 (2.7%) patients had bilateral disease. The surgical procedures included lobectomy (n=702, 50.3%), pneumonectomy (n=183, 13.1%), segmental resections (n=114, 8.2%), bilobectomy (n=83, 6.0%), and lobectomy + segmentectomy (n=312, 22.4%). During the postoperative period, 1,269 (93.5%) patients were followed at a mean duration of 51.6 (range, 1 to 120) months. After surgery, 774 (61%) patients were asymptomatic, 456 (35.9%) showed an improvement, and 39 (3.1%) had no response or deterioration. Conclusion: The surgical treatment plays an important role in the clinical and symptomatic improvement of patients with bronchiectasis. Surgery reduces the morbidity and mortality rates with careful preoperative preparation and appropriately selected cases.

Objective/Background: No studies to date have evaluated the the effect of rib-based anchors on the translational relationship between the rib and spine. We hypothesized that there would be an increase in the translational distance between the rib anchor and anterior vertebral body in early onset spinal deformity patients managed with long-term rib-based anchors. Methods: All patients with EOSD from a single tertiary level institution treated with a growth-friendly technique surgery utilizing proximal rib-based anchors from 2006-2015 with a minimum of 2-year follow-up were included. Thoracic kyphosis and the translational distance from the rib anchor to the corresponding anterior vertebral body were measured. Results: Twenty-seven patients (13 female, 14 male) qualified for inclusion. Mean age at implantation of the index proximal rib-based construct was 5±1.9 years (range, 1-9). EOSD etiology was congenital: 3, neuromuscular: 17, syndromic: 3, and idiopathic: 4. Mean kyphosis improved from 31±33° preoperatively to 25±20° immediately post-operatively. No significant changes in kyphosis were noted over 1 and 2 year follow-up (p=0.3). Twenty-one (78%) patients demonstrated an increase in translational distance from the rib anchors to the adjacent anterior vertebral body. Immediately post-operatively, mean distance was 25±1 mm and increased at 1-year (26±1 mm) and significantly at 2-year (29±1 mm) follow-up (p=0.005). Conclusion: The use of long term rib-based anchors may lead to an increase in the distance between the rib utilized for proximal fixation and the associated vertebral body, generating what appears to be increased anterior translation of the spine. This translation, in conjunction with increased or increasing overall thoracic kyphosis, may be the source of unexpected obstacles at the time of future surgical procedures for revision or final fusion.

Four immature dogs were presented with ectrodactyly. Two dogs were initially treated with distraction osteogenesis of a hypoplastic ulna and all had surgical correction of the cleft deformity. In each case proximal metacarpal apposition with or without carpal arthrodesis formed the basis of surgical treatment. Follow-up information was available for three cases and all showed improved limb function. Corrective surgery appears to be a viable alternative to amputation for treatment of ectrodacty1y.

Category: Hindfoot; Ankle; Midfoot/Forefoot Introduction/Purpose: Multiple surgical techniques are used in the correction of Adult Acquired Flatfoot Deformity (AAFD). Assessment of the efficacy of a surgical treatment in the correction of the deformity is usually performed by clinical evaluation and conventional radiographic imaging. Weightbearing CT (WBCT) allows a more reliable and multiplanar evaluation of AAFD. The Foot and Ankle Offset (FAO) is a WBCT biometric semi-automatic measurement that gauges the relative positioning between the foot tripod and the center of the ankle joint. This study aimed to investigate the efficacy of surgical treatment in correcting AAFD, comparing preoperative and postoperative FAO measurements. We hypothesized that surgical treatment would provide significant correction of the deformity, centering the tripod of the foot underneath the ankle joint. Methods: In this prospective comparative study, 21 adult patients (22 feet) with flexible AAFD were included, mean age 55 (range, 23-81) years, 13 females and eight males. Patients underwent preoperative and postoperative standing WBCT examination. Three-dimensional coordinates (X, Y and Z planes) of the foot tripod (weightbearing point of the first and fifth metatarsals and calcaneal tuberosity) and center of the ankle (apex of the talar dome) were harvested by two independent and blinded observers. The FAO was automatically calculated from the harvested 3D coordinates by dedicated software. Data regarding the surgical technique used was recorded. Patient Reported Outcomes (PROs) were collected preoperatively and postoperatively at a mean follow-up of 22 (range, 8-36) months. Pre and postoperative FAO measurements were compared by paired T-tests. Multivariate analysis was used to assess the influence of surgical procedures in the amount of FAO correction. P-values of less than 0.05 were considered significant. Results: We found excellent intra (0.98) and interobserver reliability (0.96) for FAO measurements. The mean preoperative FAO was 10.4 (95% CI, 8.5 to 12.1). There was a significant correction of the deformity postoperatively (p<0.0001), with a mean postoperative FAO of 1.4 (CI, -0.1 to 2.9), and mean improvement of 8.9 (95% CI, 6.6 to 11.2). Average increase in PROs was (p<0.05): physical function (8; CI, 4 to 12), pain interference (10.3; CI, 4.8 to 15.9), pain intensity (5.3; CI, -10:20.6), mental health (4.2; CI, 0.2:8.2), physical health (4.3; CI, 0.9 to 9.8), and depression (10.4; CI, -0.6 to 21.4). The mean number of surgical procedures performed was 8 (range, 2-12). Spring ligament reconstruction was the only technique that influenced the amount of FAO correction (P<0.001). Conclusion: To the author’s knowledge, this is the first study to assess the amount of surgical correction of AAFD using standing WBCT images and semiautomatic 3D measurements. We found that surgical treatment provided a significant and pronounced amount of correction in the FAO, with the foot tripod more centered underneath the ankle joint. We also found a significant improvement in the PROMIS after an average postoperative follow-up of 22 months. Among multiple different surgical procedures performed, reconstruction of the spring ligament was the only technique that significantly influenced the amount of FAO correction. Longer-term follow-up studies are needed. [Figure: see text]
