Advances in the Causes and Treatment of Floating Toes after the Weil Osteotomy: A Scoping Review. Orthop Surg 2024. [PMID: 38693601 DOI: 10.1111/os.14061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Revised: 03/23/2024] [Accepted: 03/24/2024] [Indexed: 05/03/2024] Open
Abstract
The floating toe deformity is classified as a forefoot deformity wherein the distal portion of the toe does not establish touch with the ground, resulting in a suspended or elevated position while the finger is in a relaxed state. At first, it garnered considerable interest as a complication It is worth noting that this condition is particularly common in children under the age of 8, which usually disappears as the individual reaches maturity. Studies have shown that with the aggravation of floating toe deformity, its adverse effects on patients' gait and overall quality of life also increase. Despite the prevalence of floating toe deformity in clinical settings, there is a lack of comprehensive literature investigating its underlying causes and potential preventive strategies. This scope review follows the preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews (PRISMA-ScR) statement guidelines for scope reviews. The literature was obtained from various full-text databases, including China National Knowledge Infrastructure Database (CNKI), Wanfang Database, PubMed, and Web of Science Database. Our search focused on published literature related to floating toes, Weil osteotomy, and distal metatarsal osteotomy, up until March 1, 2023. The literature search and data analysis are conducted by two independent reviewers. If there are any disagreements, a third researcher will participate in the discussion and negotiate a decision. Furthermore, two experienced foot and ankle surgeons conducted a thorough literature analysis for this review. Sixty-two articles were included. Through the clinical analysis of the structural changes of the forefoot before and after operation, the classification of floating toe was described, the causes of pathological floating toe were summarized, and the possible intervention measures for the disease were put forward under the advice of foot and ankle surgery experts. We comprehensively summarize the current knowledge system about the etiology of floating toe and put forward the corresponding intervention strategy. We recommend that future studies will focus on the improvement of surgical procedures, such as the combination of Weil osteotomy, proximal interphalangeal (PIP) arthrodesis and flexor tendon arthrodesis.

Radiographic Evidence of Sufficient Transverse Plane Alignment after Weil Osteotomy without Screw Fixation. J Clin Med 2024; 13:331. [PMID: 38256465 PMCID: PMC10816324 DOI: 10.3390/jcm13020331] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 01/02/2024] [Accepted: 01/03/2024] [Indexed: 01/24/2024] Open
Abstract
Weil osteotomy is a proven procedure to restore the harmonic distal parabola of the forefoot. In addition to the proximal displacement of the head in the sagittal plane, a displacement in the transverse plane may be necessary, with the refixation of the displaced metatarsal head historically performed by screw fixation. We aimed to determine the radiological differences among 136 feet of 127 patients with 256 Weil osteotomies retrospectively enrolled and divided into groups with (n = 182) and without (n = 74) screw fixation. Demographic data, radiographic union, pre- and postoperative metatarsal angles, and differences in the dorsoplantar view were evaluated. The mean follow-up period was 3.6 months. The mean preoperative metatarsophalangeal angle was 9.24°, and the mean postoperative angle was 12.99°. The restoration of the transversal alignment plane was equally successful in both groups, with a mean extent of angle correction of 10.58°. No nonunions of the osteotomized metatarsals were observed. The radiographic comparisons revealed no significant difference between the groups (p > 0.05). However, visibility of the joint space of the metatarsophalangeal joint was achieved significantly more often in the group without screw fixation (p < 0.05). In the absence of bony malunion and the satisfactory restoration of a harmonious parabola of the forefoot, apparently there does not appear to be a necessity for regular screw fixation after Weil osteotomy based on the available data from the present study.

Successful treatment of advanced Freiberg's disease with a modified Weil osteotomy, 5-year follow up: A Pilot case series with a review of the literature. Foot (Edinb) 2023; 57:101952. [PMID: 37866283 DOI: 10.1016/j.foot.2022.101952] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Revised: 04/19/2022] [Accepted: 11/13/2022] [Indexed: 11/18/2022]
Abstract
INTRODUCTION Treatment for Freiberg's disease is largely conservative. For severe disease and refractory cases, there are various surgical options. The purpose of this study was to report the 5-year clinical outcomes of a modified Weil osteotomy in the treatment of advanced Freiberg's disease. METHODS Twelve patients (12 feet), with a mean age of 30.7 years (range 17-55), were treated with synovectomy and modified Weil osteotomy of the affected distal metatarsal head. There were 10 females and 2 males. Clinical outcomes were independently evaluated pre and postoperatively using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system and a subjective satisfaction score. Radiological union was evaluated postoperatively. Nine (75%) feet involved the 2nd metatarsal and 3 feet (25%) involved the 3rd metatarsal. According to the Smillie classification, 6 feet were Grade IV and 6 feet were grade V. RESULTS No patients were lost to follow up and the mean follow-up time was 5.2 years (4-7). AOFAS scores improved from 48.1 + /- 7.4-88.9 + /- 10.1 postoperatively giving a mean improvement of 40.8 (p < 0.001). In total, 92% of patients were satisfied with their operation at latest follow-up, reporting excellent or good results. All patients had postoperative radiological union. One patient had a superficial postoperative infection that was successfully treated with oral antibiotics. CONCLUSION Modified Weil osteotomy is an effective treatment for advanced Freiberg's disease with good outcomes and few complications.

From second webspace syndrome to second cross over toe: Clinical and radiological findings following Weil osteotomy with no soft tissue procedure. Foot Ankle Surg 2023; 29:171-176. [PMID: 36646596 DOI: 10.1016/j.fas.2023.01.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2022] [Revised: 11/24/2022] [Accepted: 01/02/2023] [Indexed: 01/09/2023]
Abstract
BACKGROUND The second webspace syndrome (SWS) refers to the progressive divergence between 2nd and 3rd toes associated with pain at the second intermetatarsal space that can be confused with Morton's neuroma and treated as such without considering the underlying deformity. There is yet no consensus regarding the best treatment, from isolated soft tissue or bony procedures or a combination of both. The objective of this study was to describe the clinical characteristics of the disease, as well as to evaluate the radiological outcomes of patients with SWS treated with open Weil's osteotomy or distal metatarsal minimal invasive osteotomy (DMMO) of the second metatarsal, with main emphasis on medialization of the head in the anteroposterior plane in either procedure. METHODS A retrospective study of all patients with SWS treated with Weil's medializing osteotomy (open and percutaneous) associated or not with other forefoot procedures, treated between 2012 and 2019, was performed. Radiological variables such as metatarsal-phalangeal angle (MTPA), percentage of metatarsal uncoverage of M2 with respect to its phalanx, intermetatarsal angle (M1, M2 and M3), length of second metatarsal and intermetatarsal distance M2 - M3 were measured and compared before and after surgery. RESULTS Twenty-six patients were included, with a mean follow-up of 26 months. All patients presented divergence between the 2nd and 3rd toes, 75 % associated pain at the level of the second intermetatarsal space and two patients presented neuropathic symptoms. After surgery (nineteen open and seven DMMO), all patients rated their results as good or excellent, and the two patients with neuropathic symptoms had improvement in their symptoms. Regarding the radiological results, the percentage of subluxation of the second MTP decreased in a large percentage of the operated patients (from 43.3 % to 3.9 %) with statistical significance as well as the length of M2, IM angle between M1 - M2, IM distance between M2-M3 and the percentage of uncoverage of the second MTP (p < 0.001). CONCLUSION Medial translation associated with open Weil osteotomy or DMMO seems to correct the muscle-ligament imbalance of the second metatarsophalangeal joint and restore normal radiographic measurements, especially in the coronal and sagittal plane, without the need for soft tissue procedures, as well as the resolution of associated neuropathic symptoms in some patients. LEVEL OF EVIDENCE Level IV, retrospective case series.

The Conventional Weil Osteotomy Does Not Require Screw Fixation. J Clin Med 2023; 12:jcm12020428. [PMID: 36675357 PMCID: PMC9862780 DOI: 10.3390/jcm12020428] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 12/30/2022] [Accepted: 01/03/2023] [Indexed: 01/06/2023] Open
Abstract
The Weil osteotomy is an established procedure to reduce plantar pressure in chronic metatarsalgia. Historically, the refixation of the displaced metatarsal head is performed by screw fixation. We aimed to demonstrate that screw fixation is not always necessary. Between 2016 and 2021, 155 patients with 278 Weil osteotomies (20 males and 135 females, mean age: 63 years) were retrospectively enrolled. Group A (n = 96) underwent 195 Weil osteotomies with screw fixation; group B (n = 59), 83 without screw fixation. Demographic, Visual Analog Scale Foot and Ankle (VAS-FA), SF-12 questionnaire, and toe mobility data were recorded. The mean follow-up period was 4.5 years. The mean VAS-FA was 75.5; mean SF-12 physical component summary, 42.0; and mean SF-12 mental component summary, 51.0. The overall revision rate was 20% (group A: 25%, group B: 10.2%), primarily for arthrolysis of the metatarsophalangeal joint in group A. Clinical comparisons showed no significant difference between the groups (p > 0.05). The revision rate was significantly higher in group A (p < 0.05), with equal satisfaction in clinical outcomes. Based on the available data, the need for regular screw fixation after a Weil osteotomy cannot be justified.

Hallux valgus with second metatarsalgia: Is second metatarsal Weil osteotomy necessary? Foot Ankle Surg 2022; 28:1433-1439. [PMID: 35995690 DOI: 10.1016/j.fas.2022.08.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 07/20/2022] [Accepted: 08/02/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND The role of concomitant Weil osteotomy to address second toe metatarsalgia during hallux valgus correction is unclear. We aimed to critically analyse outcomes of an additional Weil osteotomy versus isolated Scarf osteotomy.in the management of hallux valgus and second metatarsalgia. METHODS Patients with second toe metatarsalgia who underwent first metatarsal Scarf osteotomy for hallux valgus were enrolled retrospectively. Demographics, radiographic measurements and functional outcomes were assessed at baseline, 6-months and 2-years postoperatively. Between-group significance was established with Fisher exact test, Chi-square or Mann-Whitney U test. Within-group changes from baseline were assessed with paired t-test and Wilcoxon signed-rank test. RESULTS 48 feet (34 isolated Scarf, 14 concomitant Weil osteotomy) were included. Both cohorts demonstrated significant improvements across all measures of functional outcome. However, patients with additional Weil osteotomy reported poorer short-term outcomes. CONCLUSION Superiority of additional Weil osteotomy versus isolated Scarf osteotomy in addressing second toe metatarsalgia or improving functional outcomes was not demonstrated.

Abstract
Metatarsalgia is a common problem that refers to the tenderness and pain beneath the forefoot. Many metatarsal shortening osteotomies have been described to alleviate metatarsal overload; however, these osteotomies have been associated with a high complication rate of floating toe deformity. We present a case study that describes an innovative technique for the treatment of lesser metatarsalgia that allows for the repositioning of the metatarsal head, using a stable screw fixation designed to minimize the common complication of the floating toe.

Comparison of Combination Weil Metatarsal Osteotomy and Direct Plantar Plate Repair Versus Weil Metatarsal Osteotomy Alone for Forefoot Metatarsalgia. J Foot Ankle Surg 2021; 59:303-306. [PMID: 32130995 DOI: 10.1053/j.jfas.2019.08.023] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2019] [Revised: 08/20/2019] [Accepted: 08/25/2019] [Indexed: 02/03/2023]
Abstract
Although many surgeons believe that shortening osteotomies are appropriate in patients with metatarsalgia and long second metatarsals, there remains ambiguity regarding when to repair the injured plantar plate and when to leave it alone. We prospectively assessed consecutive adult subjects who underwent an isolated second Weil metatarsal osteotomy (WMO) or a WMO plus plantar plate repair (WMO + PPR) for sub-second metatarsophalangeal joint pain during a 3.5-year period at our practice. Eighty-six patients (86 feet: 21 WMO only and 65 WMO + PPR) with a mean age of 61 ± 11 years were followed for 1 year. Patients were assessed via use of the Foot and Ankle Outcome Score and radiographic parabola/alignment of the operative digit preoperatively and postoperatively. Patients in the WMO + PPR group demonstrated significant improvements preoperatively to postoperatively in 4 of the 5 FAOS subscales (Pain, Other Symptoms, Sport and Recreation Function, and Ankle- and Foot-Related Quality of Life [QoL], all p < .05) and had higher QoL and Pain subscale scores at 1 year compared with those in the WMO-only group (QoL: 68.6 ± 26.7 versus 49.7 ± 28.5, respectively [p = .01]; Pain: 83.2 ± 14.5 versus 73.6 ± 19.9, respectively [p = .04]). The WMO + PPR group tended to have higher-grade tears on intraoperative inspection (median 3, range 0 to 4) compared with those in the WMO group (median 1, range 0 to 3). There were otherwise no group differences in preoperative or postoperative radiographic parabola, alignment of the second toe, or complication rates. Our findings suggest that when a shortening osteotomy is performed, imbricating/repairing and advancing the plantar plate may be valuable regardless of injury grade in the plate.

Abstract
OBJECTIVE To investigate the clinical and radiological outcomes in patients with monoarticular rheumatoid arthritis of the fifth metatarsophalangeal joint after Weil osteotomy. METHODS From July 2011 to September 2015, 18 feet of 16 rheumatoid arthritis patients who underwent Weil osteotomy of the fifth metatarsal toe with a mean age at the time of surgery of 48.8 ± 7.4 years were reviewed retrospectively. The mean disease duration was 44.6 ± 6.8 months, and the follow-up period was 36 months. Clinical outcomes were evaluated according to the American Orthopaedic Foot and Ankle Society lesser metatarsophalangeal interphalangeal scale (AOFAS), 10-item SF-36 physical functioning and 2-item SF-36 bodily pain, Visual Analogue Scale (VAS), and satisfaction scores. In the radiologic evaluation, fifth metatarsophalangeal angle (MTP-5), lateral deviation angle (LDA), and longitudinal axes of the fifth metatarsal were measured on anterior-posterior (AP) weight-bearing radiographs preoperative and at the last follow-up. RESULTS Clinical assessment showed that the total average of AOFAS was significantly increased from preoperative 53.6 ± 9.0 to 98.7 ± 2.0 points, and the VAS score was significantly decreased from preoperative 4.1 ± 1.5 to 1.1 ± 0.8 points at the last follow-up (P < 0.001). The total averages of SF-36 physical functioning and SF-36 bodily pain were significantly increased from preoperative 48.9 ± 9.0 to 99. ± 2.1 and from 61.4 ± 12.1 to 99.4 ± 2.4 points, respectively, at the last follow-up (P < 0.001). Subjectively, the excellent outcome of the surgery results were rated by 13 patients (81.3%) that underwent surgery and three patients (18.7%) were rated as good. Regarding radiographic parameters, the mean MTP-5 significantly decreased from 21.5° ± 1.2° preoperatively to 10.2° ± 1.2°, the mean LDA significantly decreased from 7.1° ± 1.2° preoperatively to -2.4° ± 1.0°, and the mean length of the fifth metatarsal was significantly shortened from 71.5 ± 1.4 preoperatively to 67.8 ± 1.5 mm at the final follow-up visit (P < 0.001). No malunion, nonunion, necrosis, pseudoarthrosis, or fracture of the fifth metatarsal was found. No exuberant bone growth, perforation of the screw, subluxation, or dislocation was observed. No indications of modification, revision or repeat surgery, or delayed wound healing were observed during follow-up period. CONCLUSION Surgical management of the monoarticular rheumatoid arthritis of the fifth metatarsophalangeal joint can achieve good clinical and radiological outcomes, with pain relief and dislocation reduction, as well as high satisfaction and improvement without recurrence or progression during the follow-up period.

Abstract
Hallux rigidus (HR) is one of the most common pathologies of the forefoot. The conservative treatment is indicated for early stages, while surgical treatment is required for advanced osteoarthritis and rigidity. Surgical treatment of advanced stages of HR is still controversial and includes joint-destructive procedures such as arthrodesis and arthroplasty, Weil osteotomy for decompression of the joint space may be a safe and effective procedure for the treatment of grade III HR. Twenty-four patients that underwent Weil osteotomy for Grade III HR were retrospectively reviewed. American Orthopedic Foot and Ankle Score (AOFAS), ROM and a subjective 5-point satisfaction scale were evaluated preoperatively, at 1 year, and at a minimum follow-up of 2 years. Joint space width and metatarsal length were assessed through radiographic examination preoperatively, immediately postoperatively and at 2 years follow up. AOFAS score was 45.1±3.9 preoperatively, 84.9±6.4 at 1 year and 73.7±6.2 at two years of follow up. All patients were satisfied with the procedure at 2 years follow up. Mean ROM increased from 35.1° (range, 10°- 50°) preoperatively to 80.3° (range, 60°-90°) at 1 year. Mean dorsiflexion increased from 5° (range 0° to 10°) preoperatively to 15° (range 7° to 23°) at 1 year. Both total ROM and dorsiflexion values remained constant at 2 years. The joint space was 0.5±0.9 mm preoperatively, 2.0±1.9 mm at 1 year and 1.5±1.2 mm at 2 years. The average metatarsal shortening was 2±1.4 mm. Weil osteotomy alone can be beneficial for the treatment of patients affected by advanced HR. It can improve clinical and radiological outcomes at 2 years follow up in a series of patients affected by grade III HR. Therefore, the sliding oblique osteotomy represent a valid alternative to delay more aggressive procedures.

Abstract
Introduction: Brachymetatarsia can be treated by lengthening of the affected metatarsals or shortening of the normal neighboring metatarsals. Combination of the two methods may be more effective rather than using one skill due to less complications. Case Report: A 56-year-old female patient with the bilateral first, fourth-ray brachymetatarsia underwent Weil osteotomy of the second, third, fifth metatarsals, and callotasis of the fourth metatarsal. Follow-up examination had been carried out since the surgery was done about 10 years ago. Conclusions: In the decade after observation, the patient was very satisfied with the shape and function of the feet, and no complications occurred.

Abstract
BACKGROUND The distal metatarsal metaphyseal osteotomy (DMMO) may have lower complication rates than the Weil osteotomy (WO) due to its extraarticular location and its minimal invasive nature. This study compares the clinical and radiological outcomes and complications after DMMO and WO. METHODS We compared 30 patients with WO (Group A) to 30 patients with DMMO (Group B). Ten males and 50 females with a mean age of 57.7 were included. 45 WOs and 73 DMMOs were evaluated in 60 patients. Allocation to Group A or B were random, indications comparable. The outcome was measured clinically using the Visual Analogue Scale Foot and Ankle and radiologically with an average follow up period of 13 months. RESULTS Clinical examination six weeks postoperatively showed swelling of the forefoot in 66.7% for Group A and in 73.3% for Group B. Swelling subsided in the course of time, but postoperative stiffness, lack of toe purchase and range of motion deficits did not change in the course of time. All osteotomies healed. The VAS-FA improved for both groups. Tourniquet time and operating time were lower and radiation doses higher in Group B. CONCLUSIONS The DMMO resulted in a comparable patient satisfaction and comparable radiological healing compared to WO and appears to be a valid alternative to the WO.

Abstract
To correct hallux valgus deformities in patients with advanced arthritis of the first metatarsophalangeal joint, we designed a new reverse chevron-type shortening osteotomy technique that could be used to correct valgus deformities at the proximal metatarsal level, as well as shorten and lower the metatarsal, in a 1-time procedure. Sixteen feet in 16 patients with a minimum of 18 months follow-up who underwent a shortening proximal chevron metatarsal osteotomy for a hallux valgus deformity with advanced arthritic change between January 2014 and March 2016 were reviewed in this study. Double chevron osteotomies with 20° of plantar-ward obliquity at the proximal metatarsal level were made at 5-mm intervals for simultaneous valgus correction and metatarsal shortening. An additional Weil osteotomy of the second metatarsal was performed in all feet. Patients' mean age was 57.88 ± 6.55 years. The deformity was satisfactorily corrected by the operation. The first metatarsal was shortened by approximately 8.75 mm, and the relative length of the second metatarsal did not differ significantly postoperatively (p = .179). The relative second metatarsal height, as seen on forefoot axial radiographs, was maintained constantly, with no significant difference (p = .215). No painful plantar callosity or transfer metatarsalgia under the second metatarsal head was observed postoperatively. A shortening proximal chevron metatarsal osteotomy for hallux valgus deformities with advanced arthritic change showed a good result with respect to deformity correction and pain relief. Appropriate lowering and an additional Weil osteotomy effectively prevented postoperative pain and painful callosity under the second metatarsal head.

Abstract
The plantar plate is a major structure that maintains metatarsophalangeal joint (MTPJ) stability and has only recently gained attention. Anatomic plantar plate repair can directly address the pathologic entity, rather than relying on indirect reduction of the MTPJ instability by osteotomy or tendon transfer techniques. The present report aimed to determine the effectiveness of plantar plate repair for the treatment of patients with lesser MTPJ instability. Different databases were searched using the guidelines in the Cochrane Handbook and recommendations from the Preferred Reporting Items for Systematic reviews and Meta-Analysis statement. Six case series, describing 162 patients who had undergone plantar plate repair in conjunction with either Weil osteotomy or flexor digitorum longus transfer, were retrieved. Favorable outcomes were described in each of the studies included in the present systematic review. However, these results should be interpreted with caution because of the methodologic limitations and biases inherent in the included studies. More rigorous clinical investigations are required to fully understand the effectiveness of plantar plate repair for the management of lesser MTPJ instability.

Abstract
BACKGROUND Minimally invasive surgery has a shorter surgical time, and in this study we focus on minimally invasive distal metatarsal metaphyseal osteotomy (DMMO). The operation seems to be less complex but requires a high learning curve. We report on our first patients to underline the need for extensive training and great awareness for the risks in the early learning stages. METHODS We evaluated 27 patients (mean age = 60.9 years) with a mean follow-up time of 7.2 months. Indication was metatarsalgia, intractable plantar keratosis, and the (sub-)luxation of the metatarsophalangeal joint. Clinical results were evaluated with the 12-item Short Form (SF-12), Foot Function Index (FFI), Foot and Ankle Ability Measure (FAAM), and the American Orthopaedic Foot and Ankle Score (AOFAS). Radiographs and pedobarographic analysis were obtained. RESULTS Scores ranged closely to standard value (AOFAS 88.07 points; FFI 93%; FAAM 36.4 points; SF-12 31.27 points). Pedobarography showed significant differences in several forefoot areas. We encountered nonunion/malunion and necrosis of the metatarsal head. CONCLUSIONS The aim of this study was to demonstrate the need for intensive training before practicing DMMO. Results show that minimally invasive DMMO requires a high learning curve. Correct handling of the burr is associated with a lot of training. Wrong handling can lead to nonunion/malunion or necrosis. LEVELS OF EVIDENCE Therapeutic, Level IV: Case series.

Computed tomography measurements of the lesser metatarsal heads: Anatomic considerations for surgeons performing distal metatarsal osteotomies. Foot Ankle Surg 2017; 23:230-235. [PMID: 29202980 DOI: 10.1016/j.fas.2016.05.321] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2015] [Revised: 04/24/2016] [Accepted: 05/25/2016] [Indexed: 02/04/2023]
Abstract
BACKGROUND The purpose of the current study was to provide a standardized, anatomical description of the lesser metatarsals to assist surgeons when planning distal metatarsal surgery and fixation. METHODS Eighty CT scans were included for assessment, based on a priori power analysis. Patient age was a mean 52.7±16.6 years (24-83). Metatarsals two through five were assessed in all patients. Three independent observers completed measurements for all metatarsals. Three measurements were made on all metatarsals, including a vertical height and metatarsal head and neck measurements. Statistical analysis was performed (alpha value 0.05). Inter-observer reliability was assessed for all measurements and intra-class correlation (ICC) reported. RESULTS A sequential decrease in metatarsal measurements was noted from the second to the fifth metatarsal. A mean vertical height measurement of 16.1±1.4mm (range, 13.4-19.4) was recorded for the second metatarsal, decreasing 13.0±1.1mm (range, 10.3-16.1) for fifth. There were no significant differences in metatarsal measurements based on gender in our study. Similar patient and metatarsal variability was seen head and neck measurements. Intraclass correlation coefficients (ICC) for metatarsal measurements were greater than 0.9 [95% CI; 0.936-0.991] correlation, denoting an 'excellent' interobserver reliability. CONCLUSION This study provides a baseline anatomical description of the distal metatarsals. These findings, including the variation found between patients and between metatarsal two through five, are relevant to surgeons planning and performing distal metatarsal osteotomies.

Abstract
Central metatarsal osteotomy is an effective approach in alleviating pain oriented to the forefoot. The procedures individually are straightforward in the isolated scenario. A working knowledge of the specific and unique pathobiomechanics is imperative when considering surgical intervention for the given pathologic scenario. Treating only the pain focus generally underserves the pathology and does not address the high point of the deformity. The surgeon must be cognizant of the complication potpourri, prepare the patient expectations, and engage a level of proactivity against sequelae to ensure the best possible and most predictable outcome.

Abstract
UNLABELLED In recent years, the role of the plantar plate in lesser metatarsophalangeal joint stability has increasingly been recognized. Tearing or attenuation of the plantar plate often will result in crossover or hammertoe deformity with hyperextension of the MTP joint. Some patients are able to have resolution of painful symptoms with conservative treatment but for those that fail these measures, surgical fixation of the plantar plate is indicated. While, there have been some described techniques for direct repair of the plantar plate, we present a surgical technique through a dorsal approach with a Weil osteotomy which accomplishes great clinical correction of the plantar plate tear and associated toe deformity as well as relief of patient's pain. Additionally, we believe this technique is safe, efficient and reproducible. LEVEL OF EVIDENCE Level V, expert opinion.

Abstract
Metatarsalgia, pain around the metatarsophalangeal joints, may arise from mechanical causes spontaneously or iatrogenically. Nonunion or malunion of the first metatarsal can transfer weight-bearing forces and overload the lesser metatarsals. Transfer metatarsalgia after failed hallux valgus surgery is troublesome and more prevalent than would be expected. Clinical examination of the patient allows identifying the type of transfer metatarsalgia and pathomechanics involved. This review focuses on transfer metatarsalgia after hallux valgus surgery and provides a basic understanding of the pathomechanics, clinical examination, and image studies. It also addresses the options for both conservative and surgical treatment of this challenging condition.

A modified fixation technique for a decompressional shortening osteotomy: a retrospective analysis. J Foot Ankle Surg 2014; 53:131-6.

Abstract
A long metatarsal and/or metatarsophalangeal joint dislocation associated with a digital contracture is a surgical challenge. Without appropriate surgical correction, the patient will be predisposed to numerous complications, including persistent subluxation or dislocation, recurrent metatarsalgia, dorsiflexory contracture of the digit, transfer lesions, and inadequate pain relief. The results of the present surgical treatment options have varied, with the most common complication being a floating toe. The purpose of our study was to introduce a decompression, shortening, lesser metatarsal osteotomy with a modified fixation technique using a T-plate and to report our results. Additionally, we have discussed trigonometric analysis of metatarsal declination and shortening. We retrospectively reviewed the outcomes of 30 consecutive patients with 33 osteotomies who had been treated surgically for pathologic features associated with a long metatarsal and varying biomechanical abnormalities. Before surgery, all the patients had been treated conservatively for a minimum of 3 months. The surgical procedure included a dorsal to plantar V-shaped shortening osteotomy of a lesser metatarsal that was fixated with a T plate. The patients were assessed radiographically and using the American Orthopaedic Foot and Ankle Society Lesser Metatarsophalangeal-Interphalangeal Scale and visual analog scale. The mean age at surgery was 53 (range 37 to 75) years, with a mean follow-up period of 9.1 (range 6 to 15.4) months. The average shortening of the metatarsal was 2.7 mm. One patient (3%) had had asymptomatic delayed union and 2 patients (6%) hypertrophic nonunion. No incidence of malunion or avascular necrosis was identified. Five cases (15.2%) of hardware failure occurred. The mean American Orthopaedic Foot and Ankle Society score was 76.7 postoperatively. The visual analog scale score had improved from 6.7 to 1.7. Of the 30 patients, 72% rated the overall surgical experience as excellent or good. In conclusion, the modified fixation technique for decompression, shortening metatarsal osteotomy using a T plate is a viable option when choosing a procedure to address a long, prominent metatarsal and/or digital contracture at the metatarsophalangeal joint and results in a low incidence of floating toe complications.

Abstract
BACKGROUND A floating toe deformity occurs in many patients who undergo Weil osteotomies. It is likely caused by the failure of the windlass mechanism in shortening the metatarsal. For patients who require a proximal interphalangeal (PIP) joint arthroplasty or fusion in addition to a Weil osteotomy, the transfer of the flexor digitorum brevis (FDB) tendon to the PIP joint might restore the windlass mechanism and decrease the incidence of floating toes. METHODS Fourteen cadaveric foot specimens were examined to determine the effects of changing metatarsal length as well as tensioning the FDB tendon on the angle of the metatarsophalangeal (MTP) joint as a measure of a floating toe. RESULTS Shortening and lengthening the second metatarsal resulted in a significant change in MTP angle (P = .03 and .02, respectively), though there was no clear relationship found between the amount of change in metatarsal length and the change in MTP angle. Transferring the FDB to a PIP arthroplasty site plantarflexed the MTP joint and corrected floating toes; the change in angle was significant compared with the control and shortening groups (P = .0001 and .002, respectively). CONCLUSION This study supports the theory that change in length of the metatarsal, possibly via the windlass mechanism, plays a role in the pathophysiology of the floating toe deformity. Tensioning and transferring the FDB tendon into the PIP joint helped prevent the floating toe deformity in this cadaveric model. CLINICAL RELEVANCE Continued research in this subject will help to refine methods of prevention and correction of the floating toe deformity.

Role of plantar plate and surgical reconstruction techniques on static stability of lesser metatarsophalangeal joints: a biomechanical study. Foot Ankle Int 2013; 34:1436-42.

Abstract
BACKGROUND Disruption of the plantar plate of the lesser metatarsophalangeal (MTP) joints leads to significant instability. Despite the fact that plantar plate disorders are common, the best mode of treatment remains controversial with operative treatments having variable and somewhat unpredictable clinical outcomes. METHODS Lesser MTP joints from the second, third, and fourth toes from fresh-frozen cadaver feet were biomechanically tested: (1) intact, (2) with the plantar plate disrupted, and (3) following a Weil osteotomy, a flexor-to-extensor tendon transfer, or a Weil osteotomy with a subsequent flexor-to-extensor tendon transfer with testing in superior subluxation, dorsiflexion, and plantarflexion. RESULTS The plantar plate significantly contributed to stabilizing the sagittal plane of the lesser MTP joints. The flexor-to-extensor tendon transfer significantly stabilized the disrupted lesser MTP joints in both superior subluxation and in dorsiflexion. The flexor-to-extensor tendon transfer following a Weil osteotomy also significantly stabilized the disrupted lesser MTP joints in both superior subluxation and in dorsiflexion. CONCLUSIONS In this cadaver-based experiment, disruption of the plantar plate of the lesser MTP joints led to significant instability. After plantar plate disruption, the Weil osteotomy left the joint unstable. The flexor-to-extensor tendon transfer by itself increased the stability of the joint in dorsiflexion, but combined with a Weil osteotomy restored near intact stability against superior subluxation and dorsiflexion forces. CLINICAL RELEVANCE Surgeons using the Weil osteotomy for plantar plate deficient MTP joints may consider adding a flexor tendon transfer to the procedure. Techniques to repair the torn plantar plate directly are needed.

Abstract
BACKGROUND Many procedures have been described for correction of bunionette deformity. For symptomatic type I deformity, the authors have routinely performed a subcapital oblique osteotomy of the fifth metatarsal. The purpose of this study was to report the medium-term results of this procedure. METHODS This is a retrospective review of patients who underwent subcapital oblique osteotomy for correction of type I bunionette deformity. Patients were evaluated radiographically and clinically. Sixteen feet in 14 patients were available at final follow-up. RESULTS At a mean 2.9-year follow-up, 88% of patients had good or excellent clinical result, 88% of patients had no limitation in activity, and mean pain score on a visual analog scale was 1.6 out of 10. Radiographically, a statistical difference was found when we compared the preoperative and 6-week follow-up fifth metatarsophalangeal angle; however, no statistical difference was found in the fourth to fifth intermetatarsal angle at any time or in comparison of the preoperative and final follow-up fifth metatarsophalangeal angles. CONCLUSION We found the subcapital oblique osteotomy of the fifth metatarsal to provide reliable clinical results for correction of painful type I bunionette deformity.
