Arthroscopic Lapidus Arthrodesis of the First Tarsometatarsal Joint for Treatment of Hallux Valgus Deformity of the Foot.

ABSTRACT: Hypermobility of the first tarsometatarsal joint can associate with different clinical problems, e.g., hallux valgus, hallux elevatus, hallux rigidus, and transverse metatarsalgia or arthritis of the second metarsocuneiform joint. The first tarsometatarsal joint may also contribute to other foot deformities involving the medial foot column. Osteoarthritis of this joint is one of the causes of medial foot pain. Arthrodesis of the first tarsometatarsal joint (modified Lapidus procedure) is indicated for these conditions, which are resistant to conservative treatment. Lapidus arthrodesis has several potential complications, including first metatarsal shortening, metatarsal elevates, and nonunion. Arthroscopic Lapdius arthrodesis has been reported to reduce these complications. In this Technical Note, the technical details of arthroscopic Lapidus arthrodesis is described.

Arthroscopic Arthrodesis of the First Metatarsophalangeal Joint in Hallux Valgus Deformity.

Project description:Arthrodesis of the first metatarsophalangeal joint is indicated for hallux valgus associated with degenerative changes, severe deformity, or rheumatoid arthritis and those for whom primary hallux valgus surgery has failed. Open approach requires extensive soft tissue dissection. The purpose of this Technical Note was to report the details of arthroscopic arthrodesis of the first metatarsophalangeal joint in severe and rigid hallux valgus deformity. This is a combination of endoscopic lateral release of the first metatarsophalangeal joint and arthroscopic arthrodesis of the joint. Endoscopic lateral release will convert the deformity into a flexible one and facilitate a subsequent arthrodesis procedure.

First-Tarsometatarsal Joint Alignment After First-Metatarsophalangeal Joint Arthrodesis for Hallux Valgus.

Project description:BackgroundInstability 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.MethodsRadiographs 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.ResultsOf 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).ConclusionOur 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 evidenceLevel IV, retrospective case series.

Arthroscopic Arthrodesis of the First Metatarsophalangeal Joint in Hallux Valgus Deformity Using Medial and Toe Web Portals.

Project description:Arthrodesis of the first metatarsophalangeal joint is indicated for severe hallux valgus deformity. Open arthrodesis requires extensive soft-tissue dissection. Recently, a technique of arthroscopic first metatarsophalangeal arthrodesis in hallux valgus deformity has been reported. This approach includes endoscopic lateral release of the first metatarsophalangeal joint via the plantar and toe web portals, followed by arthroscopic arthrodesis of the joint via the medial and dorsolateral portals. Endoscopic lateral release of the first metatarsophalangeal joint can convert the fixed hallux valgus deformity into a flexible one and reduce the stress over the screws and risk of loss of reduction and nonunion. The purpose of this Technical Note is to report a modified technique of arthroscopic first metatarsophalangeal arthrodesis in hallux valgus deformity. In this modified technique, the arthrodesis is performed via the medial and toe web portals and creation of the dorsolateral portal is not needed. A 2.7-mm arthroscope is used for the arthrodesis procedure instead of a 1.9-mm arthroscope. This can improve fluid inflow and visualization.

Effect on Foot Width With Triplanar Tarsometatarsal Arthrodesis for Hallux Valgus.

Project description:BackgroundFoot width reduction is a desirable cosmetic and functional outcome for patients with hallux valgus. Triplanar first tarsometatarsal (TMT) arthrodesis could achieve this goal by 3-dimensional correction of the deformity. The aim of this study was to evaluate changes in bony and soft tissue width in patients undergoing triplanar first TMT arthrodesis.MethodsAfter receiving Institutional Review Board approval, charts were retrospectively reviewed for patients undergoing triplanar first TMT arthrodesis for hallux valgus at 4 institutions between 2016 and 2019. Patients who underwent concomitant first metatarsal head osteotomies (eg, Silver or Chevron) or fifth metatarsal osteotomies were excluded. Preoperative and postoperative anteroposterior weightbearing radiographs were compared to evaluate for changes in bony and soft tissue width. One hundred forty-eight feet from 144 patients (48.1 ± 15.7 years, 92.5% female) met inclusion criteria.ResultsPreoperative osseous foot width was 96.2 mm, compared to 85.8 mm postoperatively (P < .001). Preoperative soft tissue width was 106.6 mm, compared to 99.3 mm postoperatively (P < .001). Postoperatively, patients had an average 10.4 ± 4.0 mm reduction (10.8% reduction) in osseous width and average 7.3 ± 4.0 mm reduction (6.8% reduction) in soft tissue width.ConclusionsTriplanar first TMT arthrodesis reduced both osseous and soft tissue foot width, providing a desirable cosmetic and functional outcome for patients with hallux valgus. Future studies are needed to determine if patient satisfaction and outcome measures correlate with reductions in foot width. Level of evidence: Level III, retrospective comparative study.

Modified Endoscopic Distal Soft Tissue Procedure (mEDSTP) and Arthroscopic Lapidus Arthrodesis for Correction of Severe Hallux Valgus.

Project description:Hallux valgus is one of the most common forefoot deformities faced by foot and ankle surgeons. Symptomatic deformity usually needs surgical correction. Endoscopic techniques of hallux valgus correction have been reported that are based on the same principle of the classic distal soft tissue procedure. Recently, the technique has been modified to include reconstruction of the medial metatarsosesamoid ligament and augmentation of the intermetatarsal ligament. In severe deformity or the presence of hypermobility or painful degeneration of the first tarsometatarsal joint, Lapidus arthrodesis of the joint is indicated. Arthroscopic Lapidus arthrodesis has been reported to reduce the complications associated with open procedure, including first metatarsal shortening, metatarsal elevatus, and nonunion. In this technical note, the technical details of a combined modified endoscopic distal soft tissue procedure and arthroscopic Lapidus arthrodesis is described. This is a minimally invasive approach for correction of severe hallux valgus deformity, especially that associated with ligamentous laxity.

Arthroscopic Arthrodesis of the First Metatarsophalangeal Joint in Hallux Varus.

Project description:Hallux varus deformity most commonly occurs as a complication of bunion surgery. Surgical option depends on the underlying cause, flexibility of the deformity, and presence of osteoarthritis of the first metatarsophalangeal joint. Joint-preserving surgery including medial soft tissue release, metatarsal osteotomy, and tendon transfer can be considered in flexible deformity without degeneration of the first metatarsophalangeal joint. First metatarsophalangeal arthrodesis is indicated in cases of inflammatory arthritis, avascular necrosis, osteoarthritis, neuromuscular disorder, or failed previous hallux varus corrective surgery. The purpose of this technical note is to describe the technique of arthroscopic arthrodesis of the first metatarsophalangeal joint to correct hallux varus deformity. It has the potential advantages of less surgical trauma, preservation of blood supply, less postoperative pain, and better cosmetic results.

Arthroscopic Tarsometatarsal Arthrodesis.

Project description:Tarsometatarsal (Lisfranc) osteoarthritis can be a disabling condition and is commonly due to posttraumatic causes. Tarsometatarsal arthrodesis is indicated if the pain does not subdue with conservative treatment. Classically, this is performed as an open procedure. The purpose of this technical note is to describe a minimally invasive approach of arthroscopic arthrodesis of the involved tarsometatarsal joints. The arthroscopic procedure is performed through the junction portals of the involved articulation. It has the advantages of better cosmesis, less wound complication, less bone resection, and more thorough joint debridement. However, it is contraindicated if there is an associated significant foot deformity or shortening of the involved foot rays.

First Tarsometatarsal Joint Loading After Sequential Correction of Hallux Valgus Using a Proximal Opening Wedge Metatarsal Osteotomy and Distal Soft Tissue Procedure.

Project description:BackgroundThe proximal opening wedge osteotomy (POWO) of the first metatarsal (TMT-1) is commonly performed in the operative treatment of hallux valgus. Limited work has been dedicated to study POWO's effect on the TMT-1 joint, however. The purpose of this study is to evaluate the changes in TMT-1 joint contact stress following POWO of the first metatarsal.MethodsFive fresh-frozen cadaveric below-knee specimens (mean age: 73 years) with hallux valgus deformities (mean hallux valgus angle [HVA]: 37.4 ± 8.5 degrees) were studied. The specimens were loaded to 400 N on an MTS servohydraulic load frame. Joint contact characteristics at TMT-1 joint were measured with a Tekscan pressure sensor (Model 6900, 1100 psi; Tekscan Inc, Boston, MA) with various opening wedge sizes of 3, 5, and 7 mm both without and with a distal soft tissue release (DSTR). The contact force, area, and peak contact stress were compared among groups using analysis of variance and post hoc multiple comparisons over the untreated (Dunnett test, P < .05).ResultsThe mean contact force was 47.7 ± 33.5 N for untreated specimens. This increased sequentially with opening wedge size and reached statistical significance for 7-mm opening wedge (129.7 ± 62.3 N, P = .01) and 7-mm wedge + DSTR (134.8 ± 60.5 N, P = .008). The mean peak contact stress was 2.8 ± 1.3 MPa for the untreated specimens and increased incrementally with wedge size to 5.7 ± 3.0 MPa for 7-mm wedge only (P = .03) and 5.6 ± 2.5 MPa for 7-mm wedge + DSTR (P = .05). The contact area increased with corrections, but none reached significance.ConclusionWith increasing opening wedge size, loading of the TMT-1 joint increases. Joint stresses higher than 4.7 MPa have been shown to be chondrotoxic, potentially predisposing patients to arthritic joint changes following POWO.Level of evidenceXXXXXX.

Arthrodesis of the first metatarsophalangeal joint for severe hallux valgus in adolescents with cerebral palsy: A retrospective comparison study of three surgical techniques.

Project description:PurposeWe compared the outcomes of arthrodesis of the first metatarsophalangeal joint for severe hallux valgus in 31 adolescents with cerebral palsy, using three different methods of fixation: K-wires, non-locking plates, and locking plates.MethodsClinical outcomes included time to weight-bearing, fusion rates and surgical complications. Radiographic assessment included comparing pre- and post-operative hallux valgus angles, intermetatarsal angles, interphalangeal angles, and lateral metatarsophalangeal angles. Patient-reported outcomes included pre- and post-operative visual analogue scales addressing bunion pain and concerns, difficulties with wearing shoes and braces, and difficulties with foot hygiene.ResultsOf the 31 adolescents (16 male), 10 patients had K-wire fixation, 11 had a non-locking dorsal plate, and 10 had fixation with a dorsal locking plate. Mean age at surgery was 16 years (12-18 years) and mean follow-up was 4 years (2.7-6.5 years). Patients with K-wire fixation had delayed weight-bearing and had more complications than those managed by dorsal plating. There were significant improvements in radiographic parameters (except interphalangeal angle) and in patient-reported outcomes, in all groups (p < 0.001). However, radiographic and clinical outcomes were better in the dorsal plating groups compared to the K-wire group.ConclusionArthrodesis of the first metatarsophalangeal joint gave good correction of deformity with improvements in symptoms and radiographic parameters in adolescents with cerebral palsy. We recommend dorsal plating that allowed early weight-bearing and had fewer complications with better clinical and radiographic outcomes, than K-wire fixation.Level of evidenceIV: Retrospective case series.
