Is Fibular Sesamoidectomy a Viable Option for Sesamoiditis? A Retrospective Study

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.

Or History

Adult hallux varus is an uncommon clinical entity usually caused by an inflammatory arthropathy or overcorrection during bunion reconstruction. We present five cases of unexplained spontaneous hallux varus. Clinically, all patients initially were found to have flexible deformities, and no evidence of underlying inflammatory disease or history of trauma. Symptoms were easily relieved with shoe wear modifications. Two of the patients developed more rigid deformities and subsequent medial callusing of the first toe and varus deformities of the lesser toes. These two patients eventually required surgical intervention. A Keller arthroplasty was performed on the first metatarsophalangeal joint and valgus proximal phalangeal osteotomies were done on the lateral toes when indicated. The outcome for these patients was good. Possible etiologic mechanisms are discussed. It is postulated that in these cases, the abductor hallucis tendon inserts more medially on the phalanx and overpowers the adductor. This produces a medially directed moment and, with time, a varus deformity.

Surgery First

Hallux varus is defined as a medial deviation of the phalanx at the first metatarsophalangeal joint and can be congenital or acquired. Brachymetatarsia is defined as shortening of the metatarsal bones. A combination of hallux varus and brachymetatarsia is rare. A 15-year-old girl presented to our outpatient clinic complaining of problems with her feet. A distinctive hallux varus was present bilaterally combined with a brachymetatarsia of the first metatarsals. The patient reported discomfort. She was restricted in her activities and had severe psychological strain owing to the deformity. We decided on surgery. First, a Pennig MiniFixator for callus distraction of the first metatarsal bone was applied. Owing to the increased plantar subluxation of the phalanx during distraction, an extension of the external fixator was administered so that the hallux could be repositioned to a physiologically satisfying position. After sufficient callus formation, the hardware was removed 14 weeks after surgery. Thereafter, the phalanx moved back to the subluxed position. Finally, an arthrodesis of the first metatarsophalangeal joint was performed with a locking plate. Surgery should not be made only for cosmesis and associated psychological aspects; but, discomfort should be the deciding factor. The postoperative clinical and cosmetic results in our case were good, and the patient was quite satisfied. There was no longer any preoperative discomfort and pain.

Hallux varus is most commonly seen iatrogenically following overaggressive lateral release, removal of the fibular sesamoid, or overaggressive removal of the medial eminence. There are several reported cases of traumatic hallux varus, although this is much less common. We present a case of traumatic hallux varus in a patient who was later found to have bilateral absence of her fibular sesamoids. We postulated that lack of her fibular sesamoid led to weakness of her lateral capsular ligaments, thereby making her more susceptible to this injury. We performed a repair using a split extensor hallucis longus tendon transfer that was transected proximally, rerouted the tendon under the deep transverse intermetatarsal ligament, and secured it to the first metatarsal with a Bio-Tenodesis (Arthrex, Inc, Naples, Florida) screw. At 22 months postoperatively, she has demonstrated maintenance of correction and has resumed use of normal shoe gear and participation in activities. Our goal was to demonstrate a repair for this condition that successfully maintained correction over time while still allowing for functionality of the first metatarsophalangeal joint.

Category: Midfoot/Forefoot Introduction/Purpose: Total joint replacement (TJR) and arthrodesis (A) are treatment options for severe osteoarthritis of the first metatarsophalangeal joint (MTP1). The aim of this study was to compare outcome (clinical and pedographic) of TJR (Roto- Glide) and A of MTP1. Methods: All patients that completed follow-up of at least 24 months after TJR and A of MTP1 before November 5, 2018 were included in the study. Preoperatively and at follow-up, radiographs and/or weight-bearing computed tomographies (WBCT) were obtained. Degenerative changes were classified in four degrees. Standard dynamic pedography was performed (percentage force at first metatarsal head/first toe from force of entire foot). Visual-Analogue-Scale Foot and Ankle (VAS FA) and MTP1 range of motion for dorsi-/plantarflexion (ROM) were registered and compared pre-operatively and follow-up. From November 24, 2011 until October 31, 2016, 25 TJR and 49 A were performed that completed follow-up. Results: Parameters (average values if not stated otherwise) for TJR/A were preoperatively: age 59/60 years; 7(28%)/14(29%) male; height 168/169 cm; weight 71/72 kg; degree degenerative changes 3.3/3.1; ROM 19.4/0/9.8°//20.3/0/9.2°; percentage force first metatarsal/first toe 7.9/14.6//8.5/15.3; VAS FA 45.9/46.2. Six wound healing delays were registered (TJR 2, A 4) as only complications. Follow-up time on average 45.7/46.2 and range 25.0-80.3/24.1-81.1 months. VAS FA at follow-up was 73.4/70.2.; percentage force first metatarsal/first toe 15.8/5.8//12.3/10.8; ROM 35.6/0/10.5°//10.5/0/0. Parameters did not differ between TJR and A (each p>.05) except higher force percentage first toe and lower ROM for A at follow-up (each p<.05). VAS FA and pedography parameters improved for TJR and A between preoperatively and follow-up, ROM increased for TJR and decreased for A (each p<.05). Conclusion: TJR and A were performed in similar patient cohorts regarding demographic parameter, degree of degenerative changes, ROM, pathological pedographic pattern, and VAS FA. TJR and A improved pathological pedographic pattern and VAS FA at minimum follow-up of 24 months. TJR additionally improved ROM and showed better pedographic pattern (and not different to physiological pattern) than A. Survival rate of TJR was 100% up to 6 years. In this study, TJR was a valuable alternative to A for treatment of severe MTP1 osteoarthritis.

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.

Meta Analyses

Abstract Background With continued loss of dorsiflexion of the 1st MTP, degenerative changes occur within the joint with severe restriction of movement and increase in pain, which leads to the condition known as hallux rigidus. The amount of dorsiflexion may be reduced to 0-10 degrees with pain on both active and passive motion. Objectives Systematically reviewing available evidence from published articles to assess the effectiveness of arthrodesis of first metatarsophalangeal joint by plate and screws in hallux rigidus. The assessment also would encompass safety, side effects, and complications of this mode of treatment. Materials and Methods We performed this systematic review and meta-analysis in accordance to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and Meta-analysis Of Observational Studies in Epidemiology (MOOSE) statement. PRISMA and MOOSE are reporting checklists for Authors, Editors, and Reviewers of Meta-analyses of interventional and observational studies. According to International committee of medical journal association (ICJME), reviewers must report their findings according to each of the items listed in those checklists. Results Previous results for arthrodesis have been favourable with a union rate of almost 96%. In the present systematic review and meta-analysis, the overall effect estimates showed that the union rates after plate and screw arthrodesis for 1st MTPJ was 96.2% (95% CI 94 – 98.4%). In addition, the overall effect estimates showed that the non-union rates after plate and screw arthrodesis for 1st MTPJ was 4.2% (95% CI 2.4 – 6.1%). Moreover, the overall effect estimates showed that the satisfaction rates after plate and screw arthrodesis for 1st MTPJ was 94.5% (95% CI 90 – 99%). In the present study, the overall effect estimates showed that the overall complications rate after plate and screw arthrodesis for 1st MTPJ was 7.2% (95% CI 2.5 – 12%). The overall effect estimates showed that the malunion rates after plate and screw arthrodesis for 1st MTPJ was 2.7% (95% CI 0 – 6.4%). Additionally, the overall effect estimates showed that the hardware removal and superficial infection rates after plate and screw arthrodesis for 1st MTPJ were 2% and 2.9%, respectively. Conclusion Our analysis showed that plate and screws fixation is effective techniques that can be used for first MTPJ arthrodesis in patients with hallux rigidus. We found that the screw and plate fixation has a significantly lower rate of nonunion compared with the screw alone, as reported by the literature. However, owing to the small group sizes and methodologic shortcomings, we were unable to identify the clinically superior fixation technique for first MTPJ arthrodesis arthrodesis.

Abstract Study designCase-control studyBackgroundRigid Morton’s extension (ME) are a kind of orthotics that have been used as conservative treatments of hallux rigidus (HR) named osteoarthritis, but only their effects on first metatarsophalangeal joint (MPJ) mobility and position in healthy subjects have been studied, but not on its applied forces neither in HR subjects.ObjectivesThis study sought to understand how ME orthotics with three different thicknesses could influence the kinetic first MPJ, measured dorsally using the Jack maneuver and comparing subjects with normal first MPJ mobility versus those with HR. We aimed to clarify whether tension values were different between healthy and HR subjects.Methods Fifty-eight healthy subjects were selected, of which 30 were included in the case group according to HR criteria, and 28 were included in the control group. A digital algometer was used to assess the pulled tension values (kgf) of the first MPJ during the Jack maneuver (2-mm, 4-mm, and 8-mm ME thicknesses) versus the first MPJ in the weight-bearing resting position (WRP).ResultsThe pulled tension values were reliable (ICC > 0.963). There were no statistically significant differences between the pulled tension values for the different WRP and ME conditions in the case (p = 0.969) or control (p = 0.718) groups. ConclusionsDifferent ME thicknesses had no influence on the pulled tension applied during the simulated dorsiflexion Jack maneuver.Clinical Relevance This research aims to highlight the importance of the force effects of ME when treating hallux rigidus conservatively. Our results indicate that the tension values of the first MPJ during Jack maneuver had no significant pulling force effects on ME in healthy and hallux rigidus subjects, which suggests that its prescription can be made without danger of joint overload.

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.
