Artificial intelligence(AI)and deep learning are becoming increasingly powerful tools in diagnostic and radiographic medicine.Deep learning has already been utilized for automated detection of pneumonia from chest radiographs,diabetic retinopathy,breast cancer,skin carcinoma classification,and metastatic lymphadenopathy detection,with diagnostic reliability akin to medical experts.In the World Journal of Orthopedics article,the authors apply an automated and AIassisted technique to determine the hallux valgus angle(HVA)for assessing HV foot deformity.With the U-net neural network,the authors constructed an algorithm for pattern recognition of HV foot deformity from anteroposterior highresolution radiographs.The performance of the deep learning algorithm was compared to expert clinician manual performance and assessed alongside clinician-clinician variability.The authors found that the AI tool was sufficient in assessing HVA and proposed the system as an instrument to augment clinical efficiency.Though further sophistication is needed to establish automated algorithms for more complicated foot pathologies,this work adds to the growing evidence supporting AI as a powerful diagnostic tool. 展开更多

BACKGROUND Hallux valgus(HV)is a common foot deformity that manifests with increasing age,especially in women.The associated foot pain causes impaired gait and decreases quality of life.Moderate and severe HV is a deformity that is charac-terized by the involvement of lesser rays and requires complex surgical treatment.In this study,we attempted to develop a procedure for this condition.AIM To analyse the treatment results of patients who underwent simultaneous surgical correction of all parts of a static forefoot deformity.METHODS We conducted a prospective clinical trial between 2016 and 2021 in which 30 feet with moderate or severe HV associated with Tailor’s bunion and metatarsalgia were surgically treated via a new method involving surgical correction of all associated problems.This method included a modified Lapidus procedure,M2M3 tarsometatarsal arthrodesis,intermetatarsal fusion of the M4 and M5 bases,and the use of an original external fixation apparatus to enhance correction power.Preoperative,postoperative,and final follow-up radiographic data and American Orthopaedic Foot and Ankle Society(AOFAS)scores were compared,and P values<0.05 were considered to indicate statistical significance.RESULTS The study included 28 females(93.3%)and 2 males feet(6.7%),20(66.7%)of whom had a moderate degree of HV and 10(33.3%)of whom had severe deformity.M2 and M3 metatarsalgia was observed in 21 feet,and 9 feet experienced pain only at M2.The mean follow-up duration was 11 months.All patients had good correction of the HV angle[preoperative median,36.5 degrees,interquartile range(IQR):30-45;postoperative median,10 degrees,IQR:8.8-10;follow-up median,11.5 degrees,IQR:10-14;P<0.01].At follow-up,metatarsalgia was resolved in most patients(30 vs 5).There was a clinically negligible decrease in the corrected angles at the final follow-up,and the overall AOFAS score was significantly better(median,65 points,IQR:53.8-70;vs 80 points,IQR:75-85;P<0.01).CONCLUSION The developed method showed good sustainability of correction power in a small sample of patients at the one-year follow-up.Randomized clinical trials with larger samples,as well as long-term outcome assessments,are needed in the future. 展开更多

BACKGROUND Cheilectomy of the 1^(st)metatarsophalangeal joint(MTPJ)is one of the most common procedures for the management of hallux rigidus.However,there is no consensus regarding outcomes following minimally invasive dorsal cheilectomy(MIDC)for the management of hallux rigidus.AIM To evaluate outcomes following MIDC for the management of hallux rigidus.METHODS During November 2023,the PubMed,EMBASE and Cochrane Library databases were systematically reviewed to identify clinical studies examining outcomes following MIDC for the management of hallux rigidus.RESULTS Six studies were included.In total,348 patients(370 feet)underwent MIDC for hallux rigidus at a weighted mean follow-up of 37.9±16.5 months.The distribution of patients by Coughlin and Shurna's classification was recorded in 4 studies as follows:Ⅰ(58 patients,27.1%),Ⅱ(112 patients,52.3%),Ⅲ(44 patients,20.6%).Three studies performed an additional 1^(st)MTPJ arthroscopy and debridement following MIDC.Retained intra-articular bone debris was observed in 100%of patients in 1 study.The weighted mean American orthopedic foot and ankle society score improved from a preoperative score of 68.9±3.2 to a postoperative score of 87.1.The complication rate was 8.4%,the most common of which was persistent joint pain and stiffness.Thirty-two failures(8.7%)were observed.Thirty-three secondary procedures(8.9%)were performed at a weighted mean time of 8.6±3.2 months following the index procedure.CONCLUSION This systematic review demonstrated improvements in subjective clinical outcomes together with a moderate complication rate following MIDC for the management of hallux rigidus at short-term follow-up.A moderate reoperation rate at short-term follow-up was recorded.The marked heterogeneity between included studies and paucity of high quality comparative studies limits the generation of any robust conclusions. 展开更多

Hallux valgus is a relatively common and multifaceted complex deformity of the front part of the foot. It is the result of multiple effects of innate (endogenous) and exogenous etiological factors with different degrees of influence. The degree of hallux valgus deformity is usually assessed by radiological values of hallux valgus (HV) and intermetatarsal (IM) angles. The aim of the paper is to justify the definition of hallux valgus deformity as a function of one angle, (HVA or IMA), and then to determine the functional connection and the most suitable function equalizing the values of the angles IMA and HVA. As hallux valgus is a double angulation deformity, the analytically determined connection between the HVA and IMA angles reduces the study of the deformity to the study of function with one argument, and makes the analysis of deformity changes before and after operative treatment simpler. For the determined connections between the angles, the values of linear proportionality coefficients and regression coefficients of corresponding linear functions of analytical equalization of the value of the IM angle and the degree of deformity for a given value of the HV angle were experimentally determined. The obtained results were checked on a sample of 396 operatively treated hallux valgus deformities. The presented analytical approach and the obtained functional links of IMA and HVA enable quantitative observation of the change in the degree of deformity based on the radiologically determined value of these angles, and the established nonlinear function will be useful for evaluating the expected value of the IM angle and the degree of deformity based only on the measured value of the HV angle. . 展开更多

BACKGROUND In the field of minimally invasive surgery(MIS)for the treatment of hallux valgus(HV),different techniques have begun to emerge in the literature concerning the distal osteotomy of the first metatarsal bone,the synthesis or not of the metatarsal head,the possible association with lateral soft tissues release(LSTR)and osteotomy of the base of the first phalanx.AIM To evaluate the role of LSTR on percutaneous HV correction,evaluating functional and radiographical results.METHODS From January 2012 to May 2016 a total of 396 patients with mild to moderate symptomatic HV treated with the MIS technique were included in this retrospective study.The technique provides no internal fixation(WOS).Patients were divided into the LSTR group and no LSTR group(LSTR N).This surgical procedure(LSTR)was reserved for insufficient HV angle(HVA)correction during fluoroscopic control.Patients were evaluated at each follow-up by two other authors after appropriate training by senior authors(first practitioners).Clinical evaluation was performed before surgery,6 mo after surgery,and 48 mo follow-up.American Orthopaedic Foot and Ankle Society(AOFAS)and visual analog scale(VAS)score was used to evaluate pain and function,and complications were recorded.In addition,the incidence of relapses and the degree of joint range of motion(ROM)with the association with the LSTR(capsule,adductor tendon,phalanx-sesamoid ligament,and the deep transverse metatarsal ligament)were evaluated.Radiological parameters included HVA and intermetatarsal angle(IMA).Patient satisfaction was assessed.Student t-test and Fisher exact test were used to assess statistical analysis.RESULTS From our study it is clear that no differences in term of HVA,VAS,IMA correction,rate of complications,and AOFAS score were found between groups,while a significant improvement of the same variables was found in each group between pre and postoperative values.A significant improvement in ROM at 6 mo(P=0.018)and 48 mo(P=0.02)of follow-up was found in LSTR N group.Complications were rare in both groups.CONCLUSION LSTR procedure on percutaneous HV correction seems to increase postoperative joint stiffness with a comparable incidence of relapse and a low incidence of complications. 展开更多

Background: Hallux valgus deformity is one of the most common chronic and progressive foot deformities. Surgical correction of the deformity plays a central role in the treatment of symptomatic hallux valgus. However, more than one hundred different surgical techniques have been described. Objective: To assess the radiological outcome of hallux valgus surgical correction using a scarf and akin osteotomies. Materials and methods: A cross-sectional hospital-based study was conducted on 25 adult patients (36 feet). Twenty-two females and two males with hallux valgus were treated with surgical correction using a scarf and akin osteotomies. All candidates were kept on regular postoperative, scheduled clinical follow-up programs for one year and assessed radiologically. Results: Twenty-five patients (36 feet) were included in this study. The hallux valgus angle significantly shifted to the normal range (less than 15°) after surgery, and the inter-metatarsal angle also improved to the normal range (less than 9°). Conclusion: Using scarf and akin osteotomies in treating moderate and severe hallux valgus deformity provides the satisfactory radiological outcomes in form of decreasing hallux valgus angle and inter-metatarsal angle. 展开更多

It is the result of multiple effects of endogenous and exogenous etiological factors with different degrees of influence. The degree of hallux valgus deformity was assessed by radiological values of hallux valgus (HVA) and intermetatarsal (IMA) angle. Thus, each hallux valgus deformity corresponds to a pair (HVA, IMA) of hallux valgus angle (HVA) and intermetatarsal angle (IMA) values in the plane of the deformity. The intensity of the point position vector S (HVA, IMA) in the deformation plane determined by the relation represents the absolute (conjugate) value of the power deformities. The goal of the article is to explain the advantage of the definition of the degree of hallux valgus deformity using its absolute (conjugate) value, and then to show that the degree of deformity defined in this way enables a better classification of deformities for all values of the HVA and IMA angles. Furthermore, in this article, applying the definition of conjugate deformity, analytical expressions were constructed for the assessment of the average value of deformity correction after operative treatment, as well as the error assessment of deformity correction after operative treatment. All obtained results were checked on a sample of 396 operatively treated feet. 展开更多

AIM:To define footwear outcomes following hallux valgus surgery,focusing on patient return to comfortable and heeled footwear and patterns of post-operative footwear selection.METHODS:Surgical intervention is indicated for symptomatic cases of hallux valgus unresponsive to conservative methods,with favourable reported outcomes.The return to various types of footwear postoperatively is reflective of the degree of correction achieved,and corresponds to patient satisfaction.Patients are expected to return to comfortable footwear post-operatively without significant residual symptoms.Many female patients will additionally attempt to return to high-heeled,narrow toe box shoes.However,minimal evidence exists to guide their expectations.Sixtyfive female hallux valgus patients that had undergone primary surgery bet ween 2011 and 2013 were retrospectively identified using our hospital surgical database.Patients were reviewed using a footwearspecific outcome questionnaire at a mean 18.5 mo follow-up.RESULTS:Eighty-six percent of patients were able to return to comfortable footwear post-operatively with minimal discomfort.Of those intending to resume wearing heeled footwear,62%were able to do so,with 77%of these patients wearing these as or more frequently than pre-operatively.No significant difference was observed between pre-and post-operative heel size.Mean time to return to heeled footwear was 21.4wk post-operation.Cosmetic outcomes were very high and did not adversely impact footwear selection.CONCLUSION:We report high rates of return to both comfortable and heeled shoes in female patients following primary hallux valgus surgery.We observed an"all-ornone phenomenon"where patients rejected a return to heeled footwear unless able to tolerate them at the same frequency and heel size as pre-operatively.A minority of patients were unable to return to comfortable footwear post-operatively,which had adverse ramifications on their quality-of-life.We recommend that the importance of managing patient expectations through appropriate pre-operative counselling be emphasized in forefoot surgery. 展开更多

Objective: The aim of this study was to compare two different surgical techniques for treating mild to moderate cases of hallux valgus. Methods: Forty-one patients (58 feet) with mild to moderate hallux valgus were treated by either percutaneous technique (n = 24) patients (33 feet) or by distal chevron osteotomy (n = 17) (25 feet). Results: In the percutaneous group, after a mean follow up of 49.36 months, the mean correction of hallux valgus angle (HV) was 26.69&deg;in the intermetatarsal angle, average correction was 9.45&deg;. The mean improvement of American Orthopedic Foot and Ankle Score (AOFAS) was 46.45 points. In the chevron osteotomy group, the mean follow up of 51.56 months, the mean correction of hallux valgus angle was 26.78&deg;in the intermetatarsal angle, average correction was 9&deg;. The mean improvement of AOFAS was 44.76 points. Conclusion: Both techniques gave satisfactory results. However, the percutaneous technique is safer than the distal chevron osteotomy. 展开更多

Since then a multitude of terms have been introduced referring to the same disease. The main complaints are pain especially during movement and a limited range of motion. Radiographically the typical signs of osteoarthritis can be observed starting at the dorsal portion of the joint. Numerous classifications make the comparison of the different studies difficult. If non-operative treatment fails to resolve the symptoms operative treatment is indicated. The most studied procedure with reproducible results is the arthrodesis. Nevertheless, many patients refuse this treatment option, favouring a procedure preserving motion. Different motion preserving and joint sacrificing operations such as arthroplasty are available. In this review we focus on motion and joint preserving procedures. Numer-ous joint preserving osteotomies have been described. Most of them try to relocate the viable plantar cartilage more dorsally, to decompress the joint and to increase dorsiflexion of the first metatarsal bone. Multiple studies are available investigating these procedures. Most of them suffer from low quality, short follow up and small patient numbers. Consequently the grade of recommendation is low. Nonetheless, joint preserving procedures are appealing because if they fail to relief the symptoms an arthrodesis or arthroplasty can still be performed thereafter. 展开更多

Hallux rigidus is a degenerative disease of the first metatarsalphalangeal(MTP) joint and affects 2.5% of people over age 50. Dorsal osteophytes and narrowed joint space leads to debilitating pain and limited range of motion. Altered gait mechanics often ensued as 119% of the body force transmit through the 1^(st) MTP joint during gait cycle. Precise etiology remains under debate with trauma being often cited in the literature. Hallux valgus interphalangeus, female gender, inflammatory and metabolic conditions have all been identified as associative factors. Clinical symptoms, physical exam and radiographic evidence are important in assessing and grading the disease. Non-operative managements including nonsteroidal antiinflammatory drugs, intraarticular injections, shoe modification, activity modification and physical therapy, should always be attempted for all hallux rigidus patients. The goal of surgery is to relieve pain, maintain stability of the first MTP joint, and improve function and quality of life. Operative treatments can be divided into joint-sparing vs joint-sacrificing. Cheilectomy and moberg osteotomy are examples of joint-sparing techniques that have demonstrated great success in early stages of hallux rigidus. Arthrodesis is a joint-sacrificing procedure that has been the gold standard for advanced hallux rigidus. Other newer procedures such as implant arthroplasty, interpositional arthroplasty and arthroscopy, have demonstrated promising early patient outcomes. However, future studies are still needed to validate its long-term efficacy and safety. The choice of procedure should be based on the condition of the joint, patient's goal and expectations, and surgeon's experience with the technique. 展开更多

In a long-term follow-up study (average, 6.5 years) of 112 feet (90 pa-tients) subjected to Keller’s operation for hallux valgus deformity, the author observed arelationship between Keller’s operation and the metatarsalgia which was located beneaththe central metatarsal heads. The data showed that the metatarsalgia developed or was ag-gravated in 26 feet (23%), and was eliminated or alleviated in 23 feet (21%) afterKeller’s operation. When more than one-third of the proximal phalanx of the big toe wasresected, the incidence of the metatarsalgia obviously increased following surgery. Theautho rpreferred a "Z" lengthening of the extensor hallucis longus tendon instead ofresecting excessive proximal phalanx. The total incidence of the metatarsalgia was 36%(40 feet) preoperatively and 38% (43 feet) postoperatively. This result indicated thatthere was no obvious difference in the incidence of the preoperative and postoperativemetatarsalgia. No more than one-third of the proximal phalanx of the big toe should beremoved. This seems to reduce the incidence of the metatarsalgia after Keller’s operation.After operation, the three princepal symptoms of hallux valgus deformity, painful bunionand difficulty in shoe-wearing were improved for more than 95% in the 112 feet.Eighty one% of the patients were satisfied with the result of the operation. We considerthat this method is one of the effective operation for correcting the hallux valgusdeformity and it is also important to select suitable patients. 展开更多

Background: There are at least 5 very popular methods described for the correction of mild to moderate hallux valgus deformities. Despite of reported and self experienced good results in favorable fitting preoperative anatomical conditions of some of these methods;it seems that no one is really satisfying under “difficult” or non favorable preoperative anatomic conditions. How could an optimum operation method for a satisfying correction of a mild to moderate hallux valgus look like? The well known criteria for an optimally satisfying method to achieve full normalization of important forefoot parameters under all conditions should be a lateralization, plantarization and derotation of the Ist metatarsal head and also a normalization of the distal metatarsal articular angle (DMAA) in combination with a soft tissue correction. Methods: In order to achieve this outcome without the disadvantages of shortening or the need for unloading, we developed a new operation technique and new fixation devices. We performed a simple transverse lazy-L subcapital osteotomy and after an additional soft tissue release the Ist metatarsal head was restored to its preplaned optimum position in terms of narrowing the IM angle, plantarization, correction of the hallux valgus angle, derotation of a pronation l malrotation and improvement of the DMAA. Fixation was achieved with an intramedullary angel-stable transfixed 30 mm titanium plate. The rigidity of the implant rendered interfragmental compression or solid bone contact unnecessary. The goal was only an optimal correction. All patients were allowed to ambulate with full weightbearing immediately after the operation. Results: We retrospectively reviewed 346 patients (433 feet) who underwent subcapital osteotomy between May 2007 and December 2011;308 were women and 38 men;their mean age was 65 years. The follow-up investigation was performed on average after 6.5 years (78 months);range 5.5 to 10 years (66 to 120 months). The AOFAS Score improved from 61.18 to 96.82 (t = 55.13, p ° to 4.21° (t = 89.70, p ° to 7.75° (t = 51.68, p ° to 6.61° (t = 29.34, p < 0.001). Minimal shortening of the first metatarsal (0.33 mm) and no recurrence of the deformity was observed. Conclusion: A new access to hallux valgus surgery is presented. Our results show that interfragmental compression between the osteotomy partners or good interfragmental contact is not necessary when a rigid intramedullary fixation device is used. The goal of this approach to hallux valgus surgery was to achieve excellent correction and a very rigid intramedullary angle-stable locked implant. The procedure yielded excellent results and was associated with no recurrence of hallux valgus. 展开更多

An avulsion fracture of the extensor hallucis longus at the distal end of the great toe is called “mallet toe” of the hallux. It is a rare injury and the treatment options are conservative treatment using a splint, percutaneous or open Kirschner wire fixation similar to that in the mallet finger, or suture anchor fixation. We present a case treated by the bridging technique using two suture anchors. A 57-year-old Japanese man injured his left great toe after a fall while walking barefoot on the bed. His great toe was forced into a hyperplantarflexion position. Plain radiography and computed tomography showed a small bone fragment at the base of the dorsal distal phalanx, suggesting an avulsion fracture of the extensor hallucis longus. He was treated by bridging suture technique with two suture anchors. At first, two suture anchors were inserted to the fracture bed of the distal phalanx, and then the bone fragment and extensor hallucis longus tendon were secured with two horizontal mattress sutures. Finally, bridging sutures were performed using the remaining sutures and the sutures used for mattress suturing. He obtained bony union and symmetric range of motion of the interphalangeal joint. This technique allowed us to fix the small bone fragment rigidly and mobilize the interphalangeal joint earlier to preserve the range of motion. It would be a valuable procedure when the bone fragment is small. 展开更多

Background: Moderate to severe hallux valgus deformity demands correction of the deformity. The purpose of the current study was to evaluate the results and advantages of the modified Wilson technique for treatment of hallux valgus. Twenty four operations of distal oblique osteotomies on the first metatarsal bone as described by Wilson (1963) with some modifications were performed on fifteen patients suffering from hallux valgus, done in the Department of Orthopedic Surgery and Traumatology of El-Minia University Hospital;nine of them were bilateral and six were unilateral. The osteotomy site was fixed by K. wire after displacement of the distal fragment laterally and proximally. A below the knee plaster cast was applied and the patients were encouraged to bear weight partially after the second post-operative week. The K. wire was removed after 6 weeks and the cast was removed after 10 weeks. Excellent results occurred in 18 out of 24 feet operated (75%), good in 3 feet (12.5%), fair in 2 feet (8.33%) and poor in one case (4.17%). Conclusions: These modifications added more advantages to Wilson technique as a good procedure for treatment of hallux valgus. 展开更多
