Akin Osteotomy

Background: Precision in minimal-incision surgery allows surgeons to achieve accurate osteotomies and patients to avoid risks. Herein, a surgical guide for the foot is designed and validated in vitro using resin foot models for hallux abducto valgus surgery. Methods: Three individuals with different experience levels (an undergraduate student, a master's student, and an experienced podiatric physician) performed an Akin osteotomy, a Reverdin osteotomy, and a basal osteotomy of the first metatarsal. Results: The average measurements of each osteotomy and the angle of the basal osteotomy do not reveal significant differences among the three surgeons. A shorter deviation from the planned measurements has been observed in variables corresponding to the Akin osteotomy (the maximum deviation in the measurement of the distance from the proximal medial end of the Akin osteotomy to the first metatarsophalangeal joint interline was 1.67 mm, and the maximum deviation from the proximal lateral end of the Akin osteotomy to the first metatarsophalangeal joint interline was 1.00 mm). As for the Reverdin osteotomies, the maximum deviations in the measurement of the distance from the proximal medial end of the osteotomy to the first metatarsophalangeal joint interline were 3.60 and 3.53 mm in the expert and undergraduate surgeons, respectively. All of the osteotomies were precise among the groups, reducing the learning curve to the maximum. Conclusions: The three-dimensional–printed prototype has been proven effective in guiding surgeons to perform different types of osteotomies. Minimal deviations from the predefined osteotomies were found among the three surgeons.

Peak Plantar Pressure

The effects of hallux limitus on plantar foot pressure and foot kinematics have received limited attention in the literature. Therefore, a study was conducted to assess the effects of limited first metatarsophalangeal joint mobility on plantar foot pressure. It was equally important to identify detection criteria based on plantar pressures and metatarsophalangeal joint kinematics, enabling differentiation between subjects affected by hallux limitus and people with normal hallux function. To further our understanding of the relation between midtarsal collapse and hallux limitus, kinematic variables relating to midtarsal pronation were also included in the study. Two populations of 19 subjects each, one with hallux limitus and the other free of functional abnormalities, were asked to walk at their preferred speed while plantar foot pressures were recorded along with three-dimensional foot kinematics. The presence of hallux limitus, structural or functional, caused peak plantar pressure under the hallux to build up significantly more and at a faster rate than under the first metatarsal head. Additional discriminators for hallux limitus were peak dorsiflexion of the first metatarsophalangeal joint, time to this peak value, peak pressure ratios of the first metatarsal head and the more lateral metatarsal heads, and time to maximal pressure under the fourth and fifth metatarsal heads. Finally, in approximately 20% of the subjects, with and without hallux limitus, midtarsal pronation occurred after heel lift, validating the claim that retrograde midtarsal pronation does occur.

Radiographic Alignment

Background: Instability of the first-tarsometatarsal (TMT) joint has been proposed as a cause of hallux valgus. Although there is literature demonstrating how first-TMT arthrodesis affects hallux valgus, there is little published on how correction of hallux valgus affects the first-TMT joint alignment. The purpose of this study was to determine if correction of hallux valgus impacts the first-TMT alignment and congruency. Improvement in alignment would provide evidence that hallux valgus contributes to first-TMT instability. Our hypothesis was that correcting hallux valgus angle (HVA) would have no effect on the first-TMT alignment and congruency. Methods: Radiographs of patients who underwent first-MTP joint arthrodesis for hallux valgus were retrospectively reviewed. The HVA, 1-2 intermetatarsal angle (IMA), first metatarsal–medial cuneiform angle (1MCA), medial cuneiform–first metatarsal angle (MC1A), relative cuneiform slope (RCS), and distal medial cuneiform angle (DMCA) were measured and recorded for all patients preoperatively and postoperatively. Results: Of the 76 feet that met inclusion criteria, radiographic improvements were noted in HVA (23.6 degrees, P < .0001), 1-2 IMA (6.2 degrees, P < .0001), 1MCA (6.4 degrees, P < .0001), MC1A (6.5 degrees, P < .0001), and RCS (3.3 degrees, P = .001) comparing preoperative and postoperative radiographs. There was no difference noted with DMCA measurements (0.5 degrees, P = .53). Conclusion: Our findings indicate that the radiographic alignment and subluxation of the first-TMT joint will reduce with isolated treatment of the first-MTP joint. Evidence suggests that change in the HVA can affect radiographic alignment and subluxation of the first-TMT joint. Level of Evidence: Level IV, retrospective case series.

Category: Midfoot/Forefoot Introduction/Purpose: Although the first metatarsophalangeal joint sesamoids have biomechanical value in the foot, pathologic conditions of these sesamoids are a source of disabling pain for patients, particularly during toe-off. Underlying causes include acute fracture, acute separation of bipartite sesamoids, sesamoiditis caused by repetitive trauma, infection, chondromalacia, osteochondritis dissecans, and osteoarthritis. Nonoperative treatment is the initial standard of care and has satisfactory outcomes overall, but operative management may be indicated in cases of pain refractory to conservative management. Surgical management includes tendo-Achilles or gastrocnemius lengthening, dorsiflexion osteotomy at the base of first metatarsal, corrective osteotomies, fusions for fixed pes cavus foot. Sesamoidectomy is a relatively uncommon procedure but should be considered if 6- 12 months of conservative managements fail or if the patient experiences ongoing debilitating symptoms. Methods: A retrospective chart review was conducted at our institution from 2009-2018. Twelve patients diagnosed with fibular sesamoiditis were treated with sesamoidectomy. Baseline patient demographics as well as postoperative outcomes were recorded. All patients were initially treated for an extended period conservatively with orthotics, anti-inflammatory medications, physical therapy, limitation of activity and a trial of non-weight bearing. Despite these measures, symptoms persisted for these twelve patients - all of who then underwent fibular sesamoidectomy for their symptoms. The fibular sesamoidectomy was performed by one of the three fellowship trained foot and ankle surgeons. All surgeons used plantar approach with a longitudinal incision on the lateral edge of the first metatarsal fat pad. Postoperatively, patients were kept non–weight bearing for 2 weeks and in a post-op walking shoe for 6 weeks. Results: Average age of the patients was 38 years. Ten of twelve patients (83%) were female. Majority of the patients (10) had no history of trauma, only two referred forefoot injury in the past. Average follow-up was 35 months. Two patients had both hallux valgus and hallux rigidus. One had preexisting rheumatoid arthritis with involvement of the first MTP. MRI showed 5 of 12 (42%) of patients had avascular necrosis of the sesamoid based on magnetic resonance imaging. None of the patients developed cock-up deformity of the lesser toes or hallux varus deformity, clinically or radiologically. Two patients experienced transient neuritis, one developed a superficial infection, and one had painful postoperative scarring. Hallux varus deformity was not observed in any patients. None underwent reoperation. Conclusion: Our study contradicts earlier studies which associate sesamoidectomy with high incidence of complications, particularly hallux varus. But, most of these earlier reports focus on combinations of medial, lateral, and paired excision, rather than lateral excision alone, unlike our study. Hence, fibular sesamoidectomy can be a safe, viable procedure for patients who fail conservative measures for sesamoiditis. The plantar lateral approach allows for adequate exposure of the fibular sesamoid, repair of the plantar plate, and preservation of flexor hallucis brevis, and is beneficial in preventing the occurrence of hallux varus deformity.

First Metatarsophalangeal Joint

The hallucal sesamoid bones (HSBs), having an important role in reducing load per unit area on the first metatarsal head, can be injured commonly which also affected the first metatarsophalangeal joint and the surrounding structure. Meanwhile, differences among each HSB type may be a major factor affecting the occurrence and development of HV. So far, many researchers had learned that there are three different conditions in hallucal sesamoid bone affecting the choice of clinical surgery corresponding to different solutions in clinic. Thus, it is necessary to study the anatomical morphological characteristics of the HSB which can be helpful in clinical diagnosis and treatment, especially hallux valgus (HV). 150 X-ray and three-dimensional (3D) computed tomographic (CT) images consist of 72 left and 78 right metatarsals were applied in this anatomic study between two variables and showed by a simple scatter plot. The first metatarsophalangeal joint is divided into four different types: type I (no HSB, 1.3%), type II (with one HSB, 0.07%), type IIIa (with two HSBs when THB is bigger, 28%), type IIIb (with two HSBs when FHB is bigger, 65.3%), and type IV (with three HSBs, 4.7%). There was no statistical difference between the left and right sides, except HVA, Meary, and pitch (P<0.05); all a, b, c, d, and i have statistical difference between male and female (P<0.05). Meanwhile, HVA and IMA and HVA and type group have a significant correlation. In summary, HVA and IMA and HVA and classification of HSBs have significant correlations. The classification and location of HSBs can be an important basis to choose operation methods and postoperation evaluation.

Proper Interpretation

The pathomechanics for the development of the hallux valgus deformity takes place at the first metatarsophalangeal joint-the sesamoid complex. The sesamoid complex consists of seven muscles, eight ligaments, and two sesamoid bones. When the first metatarsal escapes the complex and drifts medially, the sesamoids remain twisted in situ, several of the ligaments “fail,” and others contract. The authors propose reduction of the metatarsus primus varus by first metatarsal osteotomy and appropriate ligament releases and plications to restore alignment. A detailed understanding of the pathomechanics is essential for proper interpretation of the problems and anticipated lasting surgeries.

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.

Foot Orthosis

Context: Foot-orthosis (FO) intervention to prevent and treat numerous lower extremity injuries is widely accepted clinically. However, the results of quantitative gait analyses have been equivocal. The foot models used, participants receiving intervention, and orthoses used might contribute to the variability. Objective: To investigate the effect of a custom-molded FO intervention on multisegment medial foot kinematics during walking in participants with low-mobile foot posture. Design: Crossover study. Setting: University biomechanics and ergonomics laboratory. Patients or Other Participants: Sixteen participants with low-mobile foot posture (7 men, 9 women) were assigned randomly to 1 of 2 FO groups. Intervention(s): After a 2-week period to break in the FOs, individuals participated in a gait analysis that consisted of 5 successful walking trials (1.3 to 1.4 m/s) during no-FO and FO conditions. Main Outcome Measure(s): Three-dimensional displacements during 4 subphases of stance (loading response, mid-stance, terminal stance, preswing) were computed for each multisegment foot model articulation. Results: Repeated-measures analyses of variance (ANOVAs) revealed that rearfoot complex dorsiflexion displacement during midstance was greater in the FO than the no-FO condition (F1,14 = 5.24, P = .04, partial η2 = 0.27). Terminal stance repeated-measures ANOVA results revealed insert-by-insert condition interactions for the first metatarsophalangeal joint complex (F1,14 = 7.87, P = .01, partial η2 = 0.36). However, additional follow-up analysis did not reveal differences between the no-FO and FO conditions for the balanced traditional orthosis (F1,14 = 4.32, P = .08, partial η2 = 0.38) or full-contact orthosis (F1,14 = 4.10, P = .08, partial η2 = 0.37). Conclusions: Greater rearfoot complex dorsiflexion during midstance associated with FO intervention may represent improved foot kinematics in people with low-mobile foot postures. Furthermore, FO intervention might partially correct dys-functional kinematic patterns associated with low-mobile foot postures.

First Ray

Today, bunion surgery is still controversial. Considering that a bunion deformity in fact may be a result of multiple causes, the rationale of the currently applied techniques of surgical treatment has not been conclusively demonstrated. In view of the known hypermobility syndrome of the first ray that results in insufficient weightbearing beneath the first metatarsal head, the relationship between this syndrome and hallux valgus deformity has been investigated. The results suggest a direct relationship between painful hallux valgus deformity and hypermobility in extension of the first tarsometatarsal joint. A pathological mechanism of symptomatic hallux valgus is proposed that relates this pathology with primary weightbearing disturbances in the forefoot where angulation of the first metatarsophalangeal joint is one of the consequences. The alignment of the metatarsal heads within the sagittal plane seems to be a main concern in many hallux valgus deformities. As a consequence, treatment includes reestablishing stable sagittal alignment in addition to the horizontal reposition of the metatarsal over the sesamoid complex. As an example, first tarsometatarsal reorientation arthrodesis regulates the elasticity of the multiarticular first ray within the sagittal plane and may be the treatment of choice in many hallux valgus deformities.

Mean Time

Background: Diabetic foot infections tend to lead to amputation. Partial first-ray resections are used to help salvage the foot and maintain bipedal ambulation. Losing the first metatarsophalangeal joint has biomechanical consequences that lead to further foot deformities and result in more proximal amputations of the ipsilateral limb, such as a transmetatarsal amputation. Methods: We reviewed 48 patients (32 male and 16 female; mean age = 62.44) who underwent 50 partial first-ray resections between April 1, 2003, and July 31, 2009. These partial first-ray resections were done at various levels of the first metatarsal. We hypothesize that partial first-ray resections that require further bone resection will lead to poor biomechanics that can result in further amputation. Results: We found that out of 50 partial first-ray resections, 24 cases required further surgical intervention, 12 of which were a transmetatarsal amputation (TMA) (mean time between partial first-ray resection and TMA = 282.08 days). Forty-eight percent of patients did not require further surgical intervention and were considered a success. Conclusions: Partial first-ray resections are not highly successful. Our study found a higher success rate compared to a previous study done by Cohen et al in 1991. Partial first-ray amputations can be a good initial procedure to salvage the foot and prolong a patient’s bipedal ambulatory status, thereby lowering the patient’s morbidity and mortality.
