Comparing the Results of Using Bioabsorbable Magnesium Screw with Those Using a Titanium Screw for the Treatment of Mild to Moderate Hallux Valgus: Short-term Follow-Up

We present the short-term follow-up of 55 symptomatic hallux valgus deformities in 38 patients, treated operatively with a modification of the spike distal first metatarsal osteotomy, as described by Gibson and Piggott in 1962. The age range of the patients was 17 to 72 years at the time of surgery. The postoperative follow-up period was 12 to 55 months. Excellent and good clinical and radiographic results were recorded in 96.2% of our patients. Two of the patients (3.8%) were dissatisfied; one of them complained of metatarsalgia after the procedure, and the other had stiffness of the metatarsophalangeal joint and metatarsalgia that had been present before surgery. Three others (5.45%) required revision after early postoperative displacement but were asymptomatic subsequently. We concluded that our technique is an effective method of treating mild hallux valgus deformities with the advantages of simplicity, no shortening of the first metatarsal, and no risk of dorsal tilting of the distal fragment. Hallux valgus (lateral deviation of the great toe) is not a single disorder, as the name implies, but a complex deformity of the first ray that sometimes may involve the lesser toes. More than 130 procedures exist for the surgical correction of hallux valgus, which means that no treatment is unique. No single operation is effective for all bunions. 5 , 22 , 29 The objectives of surgical treatment are to reduce pain, to restore articular congruency, and to narrow the forefoot without impairing function, by transferring weight to the lesser metatarsals either by shortening or by dorsal tilting of the first metatarsal. 5 , 19 , 24 , 27 Patient selection is important for a satisfactory outcome after surgery of any kind, and our criteria were age, degree of deformity, presence of arthrosis, and subluxation of the first metatarsophalangeal joint. 1 , 5 , 13 , 19 – 21 , 24 , 29 In this study, we present a new method of treating hallux valgus that has been used at Mayday University Hospital since 1990. The technique was first described at the British Orthopaedic Foot Surgery Society, Liverpool, November 1990, 7 and we now present the short-term follow-up results. The procedure is essentially a modification of the spike osteotomy of the neck of the first metatarsal, as described by Gibson and Piggott. 9 It has the advantages of simplicity, no shortening of the first metatarsal, and no risk of dorsal displacement of the distal fragment.

ABSTRACT Aim The scarf osteotomy, as popularized by Barouk, is a versatile osteotomy for the correction of moderate and severe hallux valgus deformity. However, this technique requires extensive exposure, fixation, and increased operative time, and is technically demanding. We describe and present our results of a short scarf osteotomy (SSO), which retains all the cuts of a standard scarf but requires a reduced exposure, less metalwork, less operating time, and is more economical. Materials and methods All patients who underwent SSO between January 2010 and December 2012 with minimum follow-up of 12 months were eligible for the study. Preoperative, intraoperative, and postoperative radiographs were available for radiological assessment. Results In this study, 84 patients and 94 feet were included; 90% of patients were satisfied overall, with 83% of patients recommending this surgery to a friend. The hallux valgus angle improved from a preoperative mean of 30.89° (17.4—46.8) to 12° (4—30) postoperatively (p = 0.0001). The intermetatarsal angle improved from a preoperative mean of 15.05° (10.3—21.1) to 7.14° (4—15.1) postoperatively (p = 0.0001). The average sesamoid coverage improved from grade 2.18 (1—3) preoperatively to 0.57 (0—2) postoperatively (p = 0.0001). The average American Orthopedic Foot and Ankle Score improved from 51.26 (32—88) preoperatively to 91.1 (72—100) postoperatively (p = 0.0001). Conclusion We believe that this osteotomy is a novel procedure producing good to excellent results in most cases of hallux valgus. Biologically, the decreased exposure should improve healing and reduce the risk of avascular necrosis. We strongly recommend this osteotomy for most cases of hallux valgus surgery.

The senior author's (R.C.) first 25 patients (37 feet) treated with a combination proximal crescentic osteotomy and distal soft-tissue reconstruction made up the patient cohort. All 25 patients were reviewed at a minimum of one year post-op (short-term follow-up) and 20/25 (31/37 feet) were reviewed again at a mean 12.2 years (range 11.4 to 13.0 yrs) post-op (long-term follow-up). This allowed for a comparison of short- and long-term results and led to a long-term follow-up rate of 84% (31/37 feet, mean 12.2 yrs). Clinical, radiographic and patient outcome measures were obtained and compared pre-op and at short- and long-term follow-up. The mean preoperative hallux valgus (HVA) and intermetatarsal angles (IMA) were 37° and 16° respectively. The mean HVA correction was 24° and IMA correction 10° at long-term follow-up with no tendency toward recurrence. Sesamoid position and first MTP subluxation was markedly improved postoperatively and the correction was maintained at long-term follow-up. Patients were asked about their satisfaction in terms of pain, appearance and motion. At long-term follow-up, more than 90% of patients were completely satisfied with pain and motion and greater than 80% with their appearance. Ninety-four percent of patients said they would have the operation again. The AOFAS clinical rating scale for the hallux was calculated retrospectively for pre-op and short-term follow-up and prospectively for long-term follow-up. The mean pre-op score was 37/100 (16 to 60) which significantly improved to 92/100 (67 to 100) at both follow-up periods, suggesting no evidence of decrease in outcome over time. Complications included two patients (5%) that were over-corrected into varus (one symptomatic, one asymptomatic), and four patients (11%) that were undercorrected, developing asymptomatic recurrences (>10° increase HVA) at long-term follow-up. In addition, two patients (5%) developed new transfer lesions postoperatively, likely related to technical error (one varus overcorrection, one dorsiflexion malunion). In conclusion, the long-term results, with a mean follow-up of 12.2 years, of the resection realignment procedure for moderate to severe hallux valgus are generally excellent and the complication rate is low and acceptable. Attention to detail, avoiding both undercorrection, which can lead to recurrence, and overcorrection, which can cause symptomatic varus, is essential.

Category: Bunion Introduction/Purpose: The aim of this study was to explore the short-term results of third generation (using screw fixation) Minimally Invasive Chevron and Akin osteotomies (MICA) for hallux valgus correction. There is a paucity of published data regarding the outcomes of this relatively new technique. We present the largest series in the literature, using three separate validated patient-reported outcome measures (EQ-5DL, VAS Pain and Manchester Oxford Foot Questionnaire (MOXFQ), for this time point. Methods: A single surgeon case series of patients with hallux valgus underwent primary third generation minimally invasive chevron and akin osteotomies (MICA) for hallux valgus correction. Between August 2015 and January 2019, 430 MICAs were performed in 295 patients that were eligible for 1 year follow up. Baseline and 1 year post-operative patient reported outcomes were collected for 242 feet in 194 patients (182 females; 12 males). Paired t-tests were used to determine the statistical significance of the difference between pre- and post-operative scores. Results: The mean age was 55.9 (range 16.3-84.9, standard deviation (s.d.) 12.5). At one year follow up, the mean MOXFQ scores had improved for each domain: Pain; baseline 41.9 (range 0-100, s.d. 21.8), reduced to 13.8 (range 0-90, s.d. 17.7, p<0.001); Walking; baseline 34.6 (range 0-100, s.d. 24.3) reduced to 9.8 (range 0-89.0, s.d. 18.0, p<0.001); Social interaction; baseline 45.4 (range 0-100, s.d. 22.8), reduced to 8.2 (range 0-75.0, s.d. 14.7, p<0.001). Mean VAS Pain score improved from 29.8 (range 0.0-90.0, s.d. 22.1) to 8.2 (range 0.00-64.0, s.d. 12.8, p<0.001). Mean EQ-5D index score improved from 0.755 (range 0.066-1.000, s.d. 0.136) to 0.891 (range 0.350-1.000, s.d. 0.124, p<0.001). Mean EQ-5D VAS score improved from 83.4 (range 28- 100, s.d. 12.4) to 85.6 (range 0-100, s.d. 14.2, p=0.047). Conclusion: This is the largest prospective case series of short-term patient reported outcomes using a validated assessment method for hallux valgus, following third generation MICA to date. These data show that this technique is effective at improving foot and ankle specific patient reported outcomes at 1 year. This cohort is being followed over the longer term.

Category: Bunion Introduction/Purpose: Hallux Valgus (HV) is a multiplanar deformity with metatarsal varus and pronation. Pronation is a frequently undiagnosed and/or untreated deformity parameter being a recognized postoperative relapse factor. The objective of this research is to estimate the pronation prevalence in HV and evaluate the pronation correction after conventional Hallux Valgus surgery. Methods: 105 patients with operated Hallux Valgus were followed between 2010 and 2016. Mean age and follow up (months) was 53 and 23 respectively. For all patients, pre and postoperative angular measurements (Pronation angle, hallux valgus angle, HVA, and intermetatarsal angle, IMA) and the operative technique used was recorded. For pronation measurements, a 4-stage classification was used by means of 4 metatarsal templates with different degrees of pronation (0, 10, 20, 30 degrees). Surgical techniques used were Chevron, Scarf and Poscow. Results: Regarding pronation angle, 95 out of 105 patients (90%) had some degree of metatarsal pronation (10% had no pronation). The most common pronation value was 20 degrees (60%). No change in metatarsal pronation angle was observed at final follow up with any technique used. Regarding HVA and IMA pre/postoperatively: HVA: 29/11, IMA: 14/8. Chevron, Scarf and Poscow were used in 15, 67 and 23 patients respectively. 66% of cases decreased sesamoid position in one or more stages. Conclusion: Metatarsal pronation is a frequent finding in Hallux Valgus patients (90%). The most common pronation deformity is 20 degrees. It was not corrected with any technique used (Chevron, Scarf, Poscow). This fact is explained probably because these osteotomies are purely translational aiming to correct the metatarsal varus and not the metatarsal pronation.

Purpose A significant relationship between verbal short-term memory (STM) and language performance in people with aphasia has been found across studies. However, very few studies have examined the predictive value of verbal STM in treatment outcomes. This study aims to determine if verbal STM can be used as a predictor of treatment success. Method Retrospective data from 25 people with aphasia in a larger randomized controlled trial of phonomotor treatment were analyzed. Digit and word spans from immediately pretreatment were run in multiple linear regression models to determine whether they predict magnitude of change from pre- to posttreatment and follow-up naming accuracy. Pretreatment, immediately posttreatment, and 3 months posttreatment digit and word span scores were compared to determine if they changed following a novel treatment approach. Results Verbal STM, as measured by digit and word spans, did not predict magnitude of change in naming accuracy from pre- to posttreatment nor from pretreatment to 3 months posttreatment. Furthermore, digit and word spans did not change from pre- to posttreatment or from pretreatment to 3 months posttreatment in the overall analysis. A post hoc analysis revealed that only the less impaired group showed significant changes in word span scores from pretreatment to 3 months posttreatment. Discussion The results suggest that digit and word spans do not predict treatment gains. In a less severe subsample of participants, digit and word span scores can change following phonomotor treatment; however, the overall results suggest that span scores may not change significantly. The implications of these findings are discussed within the broader purview of theoretical and empirical associations between aphasic language and verbal STM processing.

Summary. Background: To assess the impact of short- vs. long-term anticoagulation in addition to standard dual antiplatelet therapy (DAPT) upon endovascular treatment of (sub)acute thrombembolic occlusions of the lower extremity. Patient and methods: Retrospective analysis was conducted on 202 patients with a thrombembolic occlusion of lower extremities, followed by crirical limb ischemia that received endovascular treatment including thrombolysis, mechanical thrombectomy, or a combination of both between 2006 and 2015 at a single center. Following antithrombotic regimes were compared: 1) dual antiplatelet therapy, DAPT for 4 weeks (aspirin 100 mg/d and clopidogrel 75 mg/d) upon intervention, followed by a lifelong single antiplatelet therapy; 2) DAPT plus short term anticoagulation for 4 weeks, followed by a lifelong single antiplatelet therapy; 3) DAPT plus long term anticoagulation for > 4 weeks, followed by a lifelong anticoagulation. Results: Endovascular treatment was associated with high immediate revascularization (> 98 %), as well as overall and amputation-free survival rates (> 85 %), independent from the chosen anticoagulation regime in a two-year follow up, p > 0.05. Anticoagulation in addition to standard antiplatelet therapy had no significant effect on patency or freedom from target lesion revascularization (TLR) 24 months upon index procedure for both thrombotic and embolic occlusions. Severe bleeding complications occurred more often in the long-term anticoagulation group (9.3 % vs. 5.6 % (short-term group) and 6.5 % (DAPT group), p > 0.05). Conclusions: Our observational study demonstrates that the choice of an antithrombotic regime had no impact on the long-term follow-up after endovascular treatment of acute thrombembolic limb ischemia whereas prolonged anticoagulation was associated with a nominal increase in severe bleeding complications.
