Category: Midfoot/Forefoot Introduction/Purpose: Hallux rigidus occurs in up to 1 in 40 adults with 1st MTPJ arthrodesis being the gold standard operation for advanced disease. Our aim was to retrospectively identify risk factors for delayed / non-union of first metatarsophalangeal joint arthrodesis using a dorsal plate with cross screw. Methods: Case note and radiograph analysis was performed for operations between April 2014 and April 2016 with at least 6 months post-operative follow up. Union was defined as bridging bone across the fusion site on AP and lateral radiographic views with no movement or pain at the MTPJ on examination. All patients operations were performed or directly supervised by one of three fellowship trained consultant foot surgeons. Surgery was performed through a dorsal approach using a dorsal locking plate with compression screw. Blinded preoperative AP radiographs were analysed for the presence of a severe hallux valgus angle equal to or above 40 degrees. Intra-observer reliability was acceptable (95% CI: 1.6-2.3 degrees). Smoking and co-morbidities underwent univariate analysis for significance. Following initial result results, surgery in patients with arthritic hallux valgus were fixed using a separate plantar to dorsal / medial to lateral lag screw and dorsal locking plate Results: 71 patients with a mean age of 61 years (range, 29 to 81) comprised the initial patient group. Mean follow up time was 13 months for both union and nonunion groups (range 6 to 30 months). 7 patients were identified as delayed or nonunion (9.9%). All had hallux valgus angles of >25%. Age, diabetes, COPD and rheumatoid arthritis did not show significant associations with non-union. All smokers progressed to union (n = 17). Moderate to severe hallux valgus (relative risk: 1.29, p < 0.005) and under correction of >25 valgus at the MTPJ (relative risk: 14.44, p < 0.001) were significantly associated with non/delayed union. In the second group, 18 patients of similar demographics, there were no failure of reductions and 100% union rate Conclusion: Preoperative moderate to severe hallux valgus and under-correction of deformity are the most significant risk factors for non-union. The construct used for fixation needs to be chosen on the basis of the deforming forces. If so, excellent union rates can be achieved

Abstract Background Scarf osteotomy (SO) was broadly applied in moderate to severe hallux valgus (MSHV), and the results were satisfactory. However, due to the complicated pathologic changes in hallux valgus, the ideal surgical treatment is still controversial. Transfer of the abductor hallucis tendon combined with Scarf osteotomy (TAHTCSO) was an innovative alternative technique. This retrospective cohort study aimed to define if TAHTCSO mode resulted in improved outcomes as compared with the single SO in MSHV. Methods Of 73 patients (92 ft) with MSHV, 36 (45 ft) were treated through TAHTCSO and 37 ones (47 ft) through SO. The patients were assessed clinically and radiographically with a 24-month follow-up. They were assessed pre-operatively and post-operatively with intermetatarsal angle (IMA), hallux valgus angle (HVA), distal metatarsal articular angle (DMAA), first metatarsophalangeal joint range of motion (1#MTP ROM), as well as American Orthopaedic Foot and Ankle Society (AOFAS) forefoot scores and postoperative complications of surgery. Results Both cohorts had the same baseline feathures. All patients were followed up from 24 to 40 months, with a mean of 28.3 months. Patients in the TAHTCSO cohort had significantly decreased HVA at 6 months (p < 0.0001), 12 months (p < 0.0001), and 24 months (p < 0.0001) after surgery. 1#MTP had been increased slightly with non-statistic sense (p>0.05). IMA, DMAA and AOFAS also had not significantly difference at all followed time after surgery as compared with the SO cohort. The healing of osteotomies was observed within 8 weeks in the two cohorts. Two cases of hallus varus had been found in SO cohort and there were no cases of delayed healing and bone non-union in both cohorts. Conclusion In this retrospective cohort study, TAHTCSO had sufficient maintenance of the correction and improved functional performance thereby was a good alternative for MSHV, though it did not display a better result for MSHV compared to SO.

Background First metatarsophalangeal joint fusion is a commonly used procedure for treating many pathologic disorders of the first ray. Historically, hallux valgus deformity with severely increased intermetatarsal angle or metatarsus primus adductus indicated need for a proximal metatarsal procedure. However, the effectiveness and reliability of first metatarsophalangeal joint arthrodesis in reducing the intermetatarsal angle has been increasingly described in the literature. We compared findings at our institution with current literature for further validation of this well-accepted procedure in correcting hallux valgus deformity with high intermetatarsal angle. Methods Weightbearing preoperative and postoperative radiographs of 43 patients, 31 women and 12 men, meeting the inclusion and exclusion criteria were identified. Two independent investigators measured the hallux abductus and intermetatarsal angles. Preoperative and postoperative measurements for each angle were compared and average reduction calculated. The data were further analyzed by grouping deformities as mild, moderate, and severe. Mean follow-up was 10 months. Results The overall mean preoperative intermetatarsal and hallux abductus angles decreased significantly (from 13.09° to 9.33° and from 23.72° to 12.19°, respectively; both P &lt; .01). When grouping deformities as mild, moderate, and severe, all of the categories maintained reduction of intermetatarsal and hallux abductus angles (P &lt; .01). Furthermore, the mean reduction of the intermetatarsal and hallux abductus angles seemed to correlate with preoperative deformity severity. Conclusions In patients undergoing correction of hallux valgus deformity, first metatarsophalangeal joint arthrodesis produced consistent reductions in the intermetatarsal and hallux abductus angles. Furthermore, these findings are consistent with those reported by other institutions.

Abstract Objective To explore the high-risk factors of augmented vertebra recompression after percutaneous vertebral augmentation (PVA) in the treatment of osteoporotic vertebral compression fracture (OVCF) and analyze the correlation between these factors and augmented vertebra recompression after PVA. Methods A retrospective analysis was conducted on 353 patients who received PVA for a single-segment osteoporotic vertebral compression fracture from January 2017 to December 2018 in our department according to the inclusion criteria. All cases meeting the inclusion and exclusion criteria were divided into two groups: 82 patients in the recompression group and 175 patients in the non-compression group. The following covariates were reviewed: age, gender, body mass index (BMI), injured vertebral segment, bone mineral density (BMD) during follow-up, intravertebral cleft (IVC) before operation, selection of surgical methods, unilateral or bilateral puncture, volume of bone cement injected, postoperative leakage of bone cement, distribution of bone cement, contact between the bone cement and the upper or lower endplates, and anterior height of injured vertebrae before operation, after surgery, and at the last follow-up. Univariate analysis was performed on these factors, and the statistically significant factors were substituted into the logistic regression model to analyze their correlation with the augmented vertebra recompression after PVA. Results A total of 257 patients from 353 patients were included in this study. The follow-up time was 12–24 months, with an average of 13.5 ± 0.9 months. All the operations were successfully completed, and the pain of patients was relieved obviously after PVA. Univariate analysis showed that in the early stage after PVA, the augmented vertebra recompression was correlated with BMD, surgical methods, volume of bone cement injected, preoperative IVC, contact between bone cement and the upper or lower endplates, and recovery of anterior column height. The difference was statistically significant (P < 0.05). Among them, multiple factors logistic regression elucidated that more injected cement (P < 0.001, OR = 0.558) and high BMD (P = 0.028, OR = 0.583) were negatively correlated with the augmented vertebra recompression after PVA, which meant protective factors (B < 0). Preoperative IVC (P < 0.001, OR = 3.252) and bone cement not in contact with upper or lower endplates (P = 0.006, OR = 2.504) were risk factors for the augmented vertebra recompression after PVA. The augmented vertebra recompression after PVP was significantly less than that of PKP (P = 0.007, OR = 0.337). Conclusions The augmented vertebra recompression after PVA is due to the interaction of various factors, such as surgical methods, volume of bone cement injected, osteoporosis, preoperative IVC, and whether the bone cement is in contact with the upper or lower endplates.

The Austin osteotomy is a widely accepted method for correction of mild and moderate hallux valgus. In view of publications by Kitaoka et al. in 1991 and by Mann and colleagues, a more radical lateral soft tissue procedure was added to the originally described procedure. From September 1992 to January 1994, 85 patients underwent an Austin osteotomy combined with a lateral soft tissue procedure to correct their hallux valgus deformities. Seventy-nine patients (94 feet) were available for follow-up. The average patient age at the time of the operation was 47.1 years, and the average follow-up was 16.2 months. The average preoperative intermetatarsal angle was 13.9°, and the average hallux valgus angle was 29.7°. After surgery, the feet were corrected to an average intermetatarsal angle of 5.8° and an average hallux valgus angle of 11.9°. Sesamoid position was corrected from 2.1 before surgery to 0.5 after surgery. The results were also graded according to the Hallux Metatarsophalangeal Interphalangeal Score, and the functional and cosmetic outcomes were graded by the patient. Dissection of the plantar transverse ligament and release of the lateral capsule repositioned the tibial sesamoid and restored the biomechanics around the first metatarsophalangeal joint. There was no increased incidence of avascular necrosis of the first metatarsal head compared with the original technique.

Category: Bunion Introduction/Purpose: Kirschner-wires fixation, sometimes we have encountered pin irritation or pull-out. This is the reason why we consider additional fixation. Moreover, there are few reports according to comparison of fixation method, and Most of them focused on comparison K-wires or screw fixation only. Purpose of study is to compare clinical and radiographic outcome between Kirschner-wires only and combined screw fixation. Methods: The study included two different groups according to fixation methods. One with Kirschner-wires fixation (KW group) included 117 feet(of 98 patients), the other with combined screw fixation (KWS group) 56 feet (of 40 patients) with moderate to severe hallux valgus. Clinically, the preoperative and final follow-up visual analog scale (VAS) pain scores, the preoperative and final follow-up American Orthopaedic Foot & Ankle Society (AOFAS) hallux metatarsophalangeal (MTP)-interphalangeal (IP) scores, and patient satisfaction after the surgery were evaluated. Radiographically, the hallux valgus angle (HVA), intermetatarsal angle (IMA), medial sesamoid position (MSP), and first to fifth metatarsal width (1-5MTW) were analyzed before and after surgery. Results: The mean AOFAS score improved preoperative 65.5 to 95.3 at final follow up in group A, while preoperative 56.5 to 88.6 at final follow up. Pain VAS decreased from 5.7 to 0.5 in group A, whereas from 6.2 to 1.6 in group B. The mean HVA all improved from preoperative 38.5 to 9.3 at final follow up in group A and 34.7 to 9.1 in group B. The mean IMA and MSP also improved significantly at final follow up. In comparative analysis, the IMA did not show significant difference between postoperative and final state in group A, while showed significant increase in group B. Conclusion: We achieved favorable clinical and radiographic outcomes with minimal complications in patient with moderate to severe hallux valgus in both groups. However, this study shows no statistically significant difference in IMA during follow-up period and lower recurrence rate. Therefore we need to consider combined fixation method to provide better stability and can expect lower recurrence rate.

Background and Purpose: The risk factors for progression in vestibular schwannomas (VSs) after incomplete resection (IR) remain to be elucidated. The purpose of this study was to investigate the risk factors for progression in remnant VSs after surgery.Methods: From January 2009 to January 2018, 140 consecutive patients who underwent IR of VSs via suboccipital retrosigmoid approach in our institution were retrospectively analyzed. During follow-up, if progression was detected, the patient was classified into Progressive Group (PG); if the residual tumor was stable or shrank, the patient was classified into Stable Group (SG). Univariate analysis and multivariate analysis were used to evaluate the risk factors for progression after IR of VSs.Results: After a mean follow-up of 80.4 months (range, 24–134 months), 35 (25.0%) patients (PG) had a progression, and no progression was detected in 105 (75.0%) patients (SG). The average tumor size was 36.5 ± 8.9 mm in PG and 31.0 ± 9.8 mm in SG, respectively. The residual tumor volume was 304.6 ± 443.3 mm3 in PG and 75.9 ± 60.0 mm3 in SG, respectively. Univariate analysis showed that preoperative tumor size, residual tumor volume, and irregular internal auditory canal (IAC) expansion were significantly different between the two groups, whereas gender, age, cystic component, or Ki-67 labeling index (LI) did not differ significantly between the two groups. Multivariate analysis showed residual tumor volume was the independent risk factor for progression.Conclusions: VSs that underwent IR with larger preoperative size, greater residual tumor volume, or irregular IAC expansion may have a higher progression rate. Strict follow-up with shorter interval in these patients to detect early progression is necessary.

Abstract Background Graciloplasty (GP) is indicated in case of recurrent rectovaginal fistula (RVF), even in patients with Crohn’s disease, after failure of previous local treatments. The aim of this study was to evaluate risk factors for GP failure performed for recurrent RVF in these patients. Methods We realised a retrospective study based on a prospective database of GP, realised in two Tertiary expert Centers in Italy (Bologna) and France (Clichy). Results Thirty-two patients undergoing 34 GP (2 patients have undergone 2 GP for failure of first GP): we excluded second GP and 2 patients without available follow-up: 30 patients undergoing a first GP for RVF (n = 29) or ileal-vaginal fistula after ileal-pouch-anal-anastomosis (IPAA) (n = 1) with a mean age of 41 ± 10 years (range, 25–64) were analysed. After a mean follow-up of 65 ± 52 months (2–183), a success of GP (considered as absence of diverting stoma and RVF healing) was noted in 17/30 patients (57%). We evaluated risk factors for failure of the procedure and we found only 2 risk factors on univariate analysis: (1) absence of a postoperative prophylactic antibiotherapy: only 2/13 (15%) patients with a GP failure had a postoperative antibiotic-prophylaxis vs. 9/15 (60%) patients with success of GP (p = 0.0238); (2) a postoperative perineal infection: 7/13 (54%) with a GP failure developed a postoperative perineal infection vs. 2/17 (12%) patients (p = 0.0196). Conclusion Graciloplasty for recurrent rectovaginal fistula in patients with Crohn’s disease is effective in 57% of patients. Our study underlines the possible benefit of a postoperative antibiotic-prophylaxis because it seems to increase significantly the success rate of the procedure.

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.
