Abstract
Claw toe deformity of the second toe is a common forefoot deformity faced by foot and ankle surgeons. Frequently, it develops as the result of plantar plate insufficiency and subsequent metatarsophalangeal (MTP) joint instability. As the disease deteriorates, the MTP joint can be dislocated. Reduction of the MTP joint without metatarsal osteotomy seems to be a logical approach unless there is excessively long second metatarsal. However, adequate periarticular soft-tissue release including the dorsal capsule, collateral ligaments and extensor tendon is needed to reduce the intra-articular pressure and minimize the risk of joint degeneration. The purpose of this Technical Note is to describe the details of plantar plate tenodesis and release of collateral ligaments for correction of claw second toe associated with dislocation of the metatarsophalangeal joint.

Abstract
The plantar plate is a vital structure for maintaining lesser metatarsophalangeal joint (MPJ) stability. Its primary role is to provide static stabilization of the MPJs, working in conjunction with the long and short flexor and extensor tendons. When insufficiency or attenuation of the plantar plate occurs, a sagittal plane deformity will slowly develop, eventually leading to a "crossover toe" transverse plane deformity. Coughlin coined this descriptive term to describe the later stages of deformity, most commonly affecting the second MPJ. Shortly after, Yu and Judge elaborated on this condition describing it as "predislocation syndrome," an inflammatory condition affecting the plantar plate causing pain and instability, which could progress to subluxation at the MPJ.

Abstract
Plantar plate deficiency is the major cause of instability of the metatarsophalangeal joint, and plantar plate tenodesis can provide dynamic stabilization of the plantar plate. In case of crossover toe deformity, incorporation of arthroscopic release of the medial capsuloligamentous complex and the lumbrical tendon can eliminate the medial deforming force. However, in case of severe deformity, the lateral capsuloligamentous complex is attenuated. The purpose of this Technical Note is to incorporate the technique of arthroscopic plication of the lateral capsuloligamentous complex into the technique of plantar plate tenodesis and arthroscopic release of the medial capsuloligamentous complex and the lumbrical tendon.

Abstract
Background: Lesser metatarsophalangeal joint (MTPJ) and plantar plate pathologies are commonly seen forefoot conditions. Traditional rebalancing techniques are commonly used but can have concerning adverse effects. The purpose of this study was to analyze the 1-year outcomes of a new technique consisting of anatomic repair of the plantar plate and collateral ligaments involving lesser MTPJs. Methodology: A retrospective cohort study of 50 consecutive patients treated with anatomic plantar plate and collateral ligament reconstruction were evaluated for lesser MTPJ imbalances between 2013 and 2016. The primary outcome was postoperative digital stability defined as a normal dorsal drawer test and normal paper pull-out test. Secondary outcomes included pre- and postoperative visual analogue scale pain measurements, MTPJ radiographic alignment, and ACFAS Forefoot module scores. Results: All patients had digital instability prior to the surgical intervention. Final follow-up revealed that 92% of patients showed improved digital stability, P = .0005. Multivariate regression found statistically significant improvement in pain reduction via the visual analogue scale of 51.2 mm (P < .0001) and ACFAS Forefoot module scores improved to 92 (P < .0001). The 45 joints with preoperative abnormal transverse plane deformity, had either complete (n = 29) or partial (n = 16) radiographic MTPJ correction. Conclusion: These results suggest that anatomic repair of lesser MTPJ improved digital stability, pain, function and radiographic alignment with greater than one year of follow-up.Levels of Evidence: Level IV: Retrospective cohort study.

Abstract
BACKGROUND Today's foot and ankle surgeon has an enhanced understanding of forefoot pathology and treatment options compared to surgeons who practiced in previous decades. This paper summarizes developments in forefoot surgery in the past 40 years, specifically in treatments for mallet toe, hammertoe, neuroma, and metatarsophalangeal joint instability. MATERIALS AND METHODS A review of the literature was conducted using the PubMed search engine, with key terms including, "mallet toe," "hammertoe," "neuroma," "metatarsophalangeal joint instability," "plantar plate," and "forefoot surgery." Chapters in major orthopaedic textbooks covering these topics were also reviewed. We then chronicled the history of the diagnosis and treatment of these pathologies, with a focus on the past 40 years. CONCLUSIONS There have been major advances in understanding and treating forefoot pathologies in the past four decades; however, there remain areas for improvement both in the diagnosis and treatment of these problems.

Abstract
Disruption of the plantar plate is a common cause of forefoot pain, metatarsalgia, and metatarsophalangeal joint malalignment. Although surgical repair of the plantar plate has improved, there has been no consensus on the clinical superiority of any single technique, or combination of techniques, described in the literature to date. In this publication, we report a case of plantar plate injury treated with an innovative new technique with 20-month follow-up.

Abstract
Metatarsalgia can be viewed as more of a symptom rather than a distinct diagnosis. Timing of forefoot pain during the gait cycle and evaluation of whether the pain is from anatomic abnormalities, indirect overloading, or iatrogenic causes can suggest a specific metatarsalgia etiology. A thorough physical examination of the lower extremity, especially evaluation of the plantar foot, and weight-bearing radiographs are critical for diagnosis and treatment. Nonoperative treatment consists of physical therapy, orthotics, shoe wear modification, and injections. If conservative treatment fails, surgical options may be considered.

Abstract
Plantar plate repairs are challenging procedures because of the small anatomy of the plantar plate. This can make them daunting, time-consuming procedures to perform. Advances in technology, such as interference screws and small suture passers, have created improved technique possibilities to decrease difficulty, correct multiple planes of deformity, create stronger constructs, and improve patient results. The plantar plate repair technique presented in this article includes a dorsal approach with a metatarsal osteotomy, a knotless repair that provides a strong construct to allow patients to protectively bear weight immediately, and can reduce operative time by presenting tips to quickly navigate the procedure. The presented technique allows for detailed correction of all three planes of deformity, maximizing patient results.

Abstract
We retrospectively evaluated the use of a suture-button technique to stabilize the plantar plate and lesser metatarsophalangeal joint (MTPJ) to alleviate pain and dysfunction due to failed digital surgery with lesser MTPJ dysfunction. Eight consecutive patients (8 feet, 13 rays) were studied, including 2 males (25%) and 6 females (75%). Their median age was 56.5 (range 25 to 72) years, and the median follow-up duration was 28 (range 21 to 36) months. Of the 8 patients, 7 (87.5%) underwent concomitant adjunct procedures. A 10-increment (equal intervals) pain score and the Bristol foot score (BFS) were used to assess subjective satisfaction and foot-related quality of life before and after surgery. The median preoperative pain score was 8 (range 5 to 10). Postoperatively, the median pain score was 0 (range 0), and the difference was statistically significant (p = .0106). The median preoperative and postoperative BFS was 53 (range 32 to 70) and 20 (range 18 to 34), respectively. The difference was also statistically significant (p = .018). One patient (12.5% of patients, 7.7% of rays) experienced wound dehiscence. All the patients indicated they would undergo the procedure again. From these findings, we believe the described suture-button technique is a useful method to stabilize the plantar plate and MTPJ after failed digital surgery.

Abstract
Lesser toe plantar plate injuries at the metatarsophalangeal (MTP) joint are a common source of metatarsalgia. The second MTP joint is the most commonly affected digit. The fibrocartilaginous plantar plate is the most important static stabilizer of the MTP joint; high loading with weight bearing can lead to attritional plantar plate injuries. Chronic pain with weight bearing is the common presentation of lesser toe instability. Untreated plantar plate instability can lead to hammer toe and mallet toe deformities. Combined Weil osteotomy and plantar plate repair yields favorable pain relief and angular deformity correction for patients who fail conservative treatment.

Abstract
Traditional rebalancing techniques, such as capsulotomies and capsulorrhaphies, are commonly performed during complex hammertoe and lesser metatarsal osteotomy procedures involving metatarsophalangeal joint (MTPJ) contractures; however, floating toes, digital instability, and malalignment are concerns. We critically analyzed the outcomes after anatomic reconstruction of the plantar plate and collateral ligaments compared with those after traditional rebalancing techniques. A case-control study was conducted of 54 patients who had undergone surgical correction of lesser MTPJ imbalances due to complex hammertoe deformities (power 80%, type I error = 0.05). Cases were defined as consecutive patients treated with anatomic plantar plate and collateral ligament reconstruction. Controls had undergone traditional lesser MTPJ rebalancing and were matched to cases by age, gender, follow-up duration (minimum 12 months), and concomitant procedures of the same lesser ray. Multivariate logistic regression demonstrated that patients treated with anatomic reconstruction had greater digital stability (negative dorsal drawer and negative paper pull-out test findings) at final follow-up examination compared with the controls. American College of Foot and Ankle Surgeons (ACFAS) forefoot module scores were greater in the anatomic group in all domains (p ≤ .05). Controls had greater postoperative radiographic MTPJ angles than the cases, with no differences detected between the 2 groups in visual analog scale scores or proximal interphalangeal joint angles. The importance of restoration of the plantar plate and collateral ligament integrity as a digital stabilizer is generally accepted but has not been well studied. We found that anatomic reconstruction yielded greater digital stability, greater ACFAS Forefoot module scores, and better radiographic MTPJ alignment than controls. Additional studies are warranted to assess the long-term viability of anatomic lesser MTPJ reconstruction.

Abstract
BACKGROUND Metatarsophalangeal joint instability of the lesser toe can cause acquired toe deformity. Plantar plate deficiency is the major pathology. Plantar plate repair can stabilize the joint but may result in iatrogenic transverse plane toe deformity in correction of claw toe deformity. Limited toe extension can be resulted after correction of crossover toe deformity by plantar plate tenodesis and extensor digitorum brevis transfer. A modification of the technique is proposed. MATERIALS AND METHODS The clinical outcomes of 10 patients with the modified procedure performed were assessed. RESULTS The correction was full in all toes with no recurrence. CONCLUSION The modified technique can stabilize the metatarsophalangeal joint and correct lesser toe deformity without the need of tendon transfer, osteotomy or sophisticated instrumentation.

Abstract
The causes of metatarsalgia are classified as primary, secondary, and iatrogenic. Anatomical and biomechanical considerations separate "static" from "propulsive" forms of metatarsalgia. The physical examination should be combined with an assessment of weight-bearing radiographs and, if needed, of ultrasound or magnetic resonance imaging scans. The first-line treatment is conservative (stretching exercises, footwear modification, insoles, and lesion debridement). Soft-tissue surgical procedures (gastrocnemius muscle recession, tendon transfer, and plantar plate repair) should also be considered. Among the various types of metatarsal osteotomy, the Weil procedure is reliable. Percutaneous methods are being developed but require evaluation. A treatment algorithm can be developed based on whether the hallux is normal or abnormal. Metatarsalgia due to inflammatory disease requires a specific treatment strategy.

Abstract
Direct plantar plate repair using a plantar approach has been described previously, but with few reports of the outcomes or clinical results. The purpose of the present study was to determine the outcomes of this technique. We performed a retrospective analysis of patients who had undergone direct plantar plate repair with or without concomitant Weil osteotomy and a prospective patient-reported subjective outcomes analysis. Ultimately, 131 patients (144 toes) were included, and the response rate for the mailed surveys was 53.5% (77 of 144 toes). The clinical outcomes reported a well-aligned toe in 87.1% of cases, with a recurrence rate of 7.6% (11 of 144) and a revision rate of 2.8% (4 of 144). Statistically significant improvement in the overall modified Foot Function Index (p < .001) and subscale scores for pain (p < .001), disability (p < .001), and activity limitation (p = .001) were noted postoperatively compared with the preoperative data. The median postoperative visual analog pain scale level reported at survey completion was 2.0 (range 0.0 to 10.0; mean ± standard deviation 2.3 ± 2.6). Despite the modified Foot Function Index scores, the patient satisfaction questionnaire data reported mixed results. Our modified Foot Function Index results demonstrated that this approach provides excellent postoperative pain relief, improvement of associated disability, and improvement in activity limitations. The importance of managing patient expectations is acknowledged secondary to the discrepancy with the patient satisfaction data and the modified Foot Function Index results. Further prospective study is warranted to compare this technique with alternate dorsal approaches for plantar plate repair with and without associated commercially available suture passing systems.

Abstract
Plantar plate deficiency is the major pathology causing metatarsophalangeal joint instability. As the joint subluxates dorsally, the lumbrical is tethered at the medial side of the joint by the deep metatarsal ligament and becomes a deforming force for the development of crossover toe deformity. Plantar plate repair or reconstruction is a logical surgical treatment option. This can be performed through a dorsal or plantar approach. The purpose of this technical note is to report a minimally invasive technique of crossover toe deformity correction by suturing the plantar plate to the extensor tendon. It is indicated for symptomatic crossover toe deformity that is not responsive to nonsurgical treatment. It is contraindicated if the metatarsophalangeal joint is degenerated, destructed, or dislocated, or there is interdigital neuroma at the sides of the deformed toe, or the deformity is caused by bony deformities of the metatarsal head or the proximal phalanx.

UNLABELLED Plantar plate pathology has gained considerable attention in recent time, and with this increased awareness multiple treatments have been proposed. There have been no comparison studies between these treatments. The authors feel a direct approach for anatomic repair allows for plantar plate repair and tightening to desired tension, without any plantar prominences or potentially irritating hardware. In addition if the plantar plate is found to be attenuated or there is a lack of residual tissue, the described imbrication utilizing the flexor digitorum longus sheath, which is not possible with hardware or newest instrumentation, allows for a robust repair. The presented case series provides results from consecutive patients treated with proposed concurrent plantar and dorsal incisions, providing proof of concept and viability of novel technique.

Abstract
Objective To find the best clinical parameters for defining and classifying the degree of plantar plate injuries. Method Sixty-eight patients (100 metatarsophalangeal joints) were classified in accordance with the Arthroscopic Anatomical Classification for plantar plate injuries and were divided into five groups (0 to IV). Their medical files were reviewed and the incidence of each parameter for the respective group was correlated. These parameters were: use of high heels, sports, acute pain, local edema, Mulder's sign, widening of the interdigital space, pain in the head of the corresponding metatarsal, touching the ground, “drawer test”, toe grip and toe deformities (in the sagittal, coronal and transversal planes). Results There were no statistically significant associations between the degree of injury and use of high-heel shoes, sports trauma, pain at the head of the metatarsal, Mulder's sign, deformity in pronation or displacement in the transversal and sagittal planes (although their combination, i.e. “cross toe”, showed a statistically significant correlation). Positive correlations with the severity of the injuries were found in relation to initial acute pain, progressive widening of the interdigital space, loss of “touching the ground”, positive results from the “drawer test” on the metatarsophalangeal joint, diminished grip strength and toe deformity in supination. Conclusions The “drawer test” was seen to be the more reliable and precise tool for classifying the degree of plantar plate injury, followed by “touching the ground” and rotational deformities. It is possible to improve the precision of the diagnosis and the predictions of the anatomical classification for plantar plate injuries through combining the clinical history and data from the physical examination.

Abstract
BACKGROUND Instability of the lesser metatarsophalangeal (MTP) joints is a common cause of deformity and pain. The purpose of this study was to prospectively evaluate the surgical outcomes for the different grades of plantar plate tears and propose a treatment protocol. METHODS Sixty-eight patients (100 MTP joints) were prospectively enrolled and graded according to the anatomical grade system for plantar plate tears. Based on this classification, the appropriate surgical procedure was chosen as follows: grades 0 and I, thermal shrinkage with radiofrequency; grades II and III, direct reinsertion of the plantar plate; and grade IV, flexor-to-extensor tendon transfer. All surgical procedures were associated with a Weil metatarsal osteotomy. Evaluations were performed before and after surgical treatment with a mean follow-up of 2 years (12-36 months), using clinical and radiological parameters: American Orthopaedic Foot and Ankle Society (AOFAS) Lesser MTP-IF Scale, visual analog scale (VAS), ground touch, joint stability, and toe purchase. RESULTS The analysis of the clinical parameters demonstrated a significant improvement of all groups (P < .0001) after surgical treatment, but grade IV had less VAS improvement and a fair AOFAS average score (72 points). All groups improved regarding physical examination parameters, but grade I, III, and IV tears had proportionally less stable MTP joints following surgery, as well as a lower proportion of normal postoperative toe purchase and ground touch. All groups showed a significant improvement regarding radiographic parameters. CONCLUSION All groups of operatively treated patients had significant improvement with regard to subjective and objective parameters. Grades I, III, and IV presented inferior results compared with grades 0 and II. LEVEL OF EVIDENCE Level IV, case series.

Abstract
Lesser metatarsophalangeal joint instability is a challenging disorder for the foot and ankle surgeon to repair. We believe that disruption of the plantar plate is common, and its repair should be carefully considered. However, we believe that most current techniques inadequately address repair of the complete plantar plate ligament tear, and, thus, instability and pain commonly persist after disruption of the plantar plate. In the present report, we present a technique we have found useful for repair of a complete plantar plate ligament rupture. The method we have described uses interference screw fixation through a dorsal incision to stabilize the lesser metatarsophalangeal joint.

Abstract
Our understanding of lesser toe metatarsophalangeal joint instability has increased substantially over the past few decades. Some recent articles on the subject have provided detailed anatomic descriptions that help to characterize the primary stabilizing structures of the joint. Some surgeons now advocate the incorporation of a primary repair of the plantar plate into the surgical plan for correction of metatarsophalangeal joint deviation in the sagittal and transverse planes. New surgical techniques have been developed to expose, inspect, and reliably repair the plantar plate, if necessary. Dorsal and plantar approaches have both been used successfully to repair the plantar plate. Tears of the plantar plate can be repaired primarily or advanced on the base of the proximal phalanx through bone tunnels. Outcomes of these procedures are promising, with improvements in pain and function reported along with sustained deformity correction.

Abstract
Tears of the plantar plate can be a source of significant forefoot pain, leading to alterations of foot function and gait. The objective of the present retrospective study was to further determine the value of ultrasound imaging in diagnosing plantar plate tears after clinical evaluation through a comparison of the ultrasound and intraoperative examination findings. Eight patients were identified who had undergone surgical intervention for a painful lesser metatarsophalangeal joint after ultrasound examination to diagnose a plantar plate pathologic entity. The intraoperative examination findings were used to calculate the sensitivity, specificity, and positive and negative predictive values of ultrasound in the diagnosis of plantar plate tears. The sensitivity and specificity of the ultrasound examination was 1 and 0.6, respectively. The positive and negative predictive value was 0.6 and 1, respectively. An ultrasound examination in the diagnosis of lesser metatarsophalangeal joint plantar plate tears displayed comparable sensitivity in identifying the pathologic features when compared with magnetic resonance imaging, with considerably less financial cost for the examination.

Abstract
Dorsal instability of the metatarsophalangeal joint (MTPJ) of the lesser toes is an important cause of forefoot pain. Both conservative and surgical treatment options have been proposed. However, the role of each static stabilizing structure has not been elucidated. We hypothesized that isolated sectioning of the plantar plate (PP) would result in greater dorsal translation compared to isolated sectioning of the medial collateral ligaments (MCL) or lateral (LCL) collateral ligaments, or the extensor hood (EH), and that combined injury to two or more structures would result in greater dorsal translation compared to isolated PP injury. Fifty-four cadaveric lesser toe specimens were randomized into groups for individual and combined sectioning of the PP, EH, and LCL and MCL. A 30 N axial load was applied to each specimen in the plantar-dorsal direction and dorsal translation of the phalanx was measured for each condition. ANOVA was used to compare groups. A 19% change in MTP translation was found from intact after sectioning the PP. No significant difference in translation was seen after individual sectioning of the EH, MCL, or LCL. A significant increase in translation occurred from intact with the following sectioning combinations: MCL + LCL, 37%; EH + MCL + LCL, 45%; and PP + MCL + LCL, 63%. Thus, the PP is the main restraint for dorsal MTPJ translation. MCL and LCL have important partial contribution to MTPJ stability. Injury to the PP, individually, or combined injuries to the PP, EH, MCL, or LCL, appear to cause significant instability that may warrant more aggressive treatment.

Abstract
BACKGROUND Lesser metatarsophalangeal joint (MTPJ) instability is a common complaint. The role each of the collateral structures play in maintaining joint stability is unknown. METHODS Twenty-six fresh-frozen cadaver lesser MTPJ's were tested for instability with the amount of force necessary to translate the joint 3 mm dorsally. Specimens were tested with 1) intact collateral ligaments, 2) transected accessory collateral or proper collateral ligaments (ACL or PCL), 3) repaired ACL or PCL, 4) transected ACL and PCL, 5) repaired ACL and PCL, and 6) transferred interosseous (IO) tendon. Student t-tests were performed to test for statistical significance (p value less than 0.05). RESULTS The mean force required for 3 mm of dorsal displacement was 25 ± 13 N (range, 11 to 52 N) in the 26 specimens. Transecting either the ACL alone or the ACL and PCL led to the most instability versus transecting the PCL alone. Repairing both ligaments improved stability. The IO tendon transfer was comparable to the direct repair of the PCL but was inferior to the direct repair of the ACL. CONCLUSION Both ACL and PCL have a stabilizing effect on the MTPJ. However, the ACL was more important since primary transection of the ACL led to more instability and additional transection of the PCL in an ACL deficient model did not lead to significantly more instability. CLINICAL RELEVANCE Direct repairs of both structures improved the stability of the joint but not back to normal. IO tendon transfer is a possible adjunct to collateral ligament repairs, but in itself is not sufficient to restore stability.

Abstract
Plantar plate rupture is a common cause of forefoot pain, multiplanar malalignment, subluxation, or dislocation of the metatarsophalangeal joint (MTPJ). The treatments that have been described for MTPJ instability of lesser toes include amputation, lengthening and/or tendon transfer, periarticular soft-tissue release (capsule, collateral ligaments, and plantar plate), colateral ligament reconstruction, metatarsal shortening osteotomy, and suture of plantar plate lesion. This article outlines the anatomy, pathogenesis, and diagnosis of plantar plate rupture, and describes a new technique that combines joint decompression by Weil osteotomy with a plantar plate repair using a pull-out technique.

Abstract
In cases of painful complex hammertoe deformity, there is no single approach that can be used in all circumstances. If conservative care fails, surgical management may include interphalangeal joint arthroplasty, arthrodesis, and/or plantar plate repair. The best and most pragmatic surgical plan must be patient-centered, taking the age, activity level, expectations of the patient, and precise etiology of the hammertoe deformity into account.

Abstract
BACKGROUND Ligamentous and capsular insufficiency of the second metatarsophalangeal joint has been surgically treated for over two decades, mainly with indirect surgical repairs, which stabilize adjacent soft tissue and shorten or decompress the osseous structures. While ligamentous insufficiency has been described and recognized, degeneration of the plantar plate and tears of the capsule have rarely been documented. The purpose of this study was to document and describe the presence and pattern of plantar plate tears in specimens with crossover second toe deformities, and based on this, to develop an anatomical grading system to assist in the assessment and treatment of this condition. METHODS Sixteen below-knee cadaveric specimens with a clinical diagnosis of a second crossover toe deformity were examined, and dissected by removing the metatarsal head. The pathologic findings of plantar plate and capsular pathology, as well as ligamentous disruption, were observed and recorded. Demographics of the specimens were recorded, and simulated weightbearing radiographs were obtained prior to dissection so that pertinent angular measurements could be obtained. RESULTS Demographics demonstrated a high percentage of female specimens, and a typically older population that has been reported for this condition. Radiographic findings documented a high percentage of hallux valgus and hallux rigidus deformities. The MTP-2 and MTP-3 angles were divergent consistent with a crossover toe deformity. We consistently found transverse tears in the plantar plate region immediately proximal to the capsular insertion on the base of the proximal phalanx. With increasing deformity, wider distal transverse tears extending from lateral to medial were found. Midsubstance tears, collateral ligament tears, and complete disruption of the plantar plate were found in more severe deformities. CONCLUSION In this largest series of cadaveric dissections of crossover second toe deformities, we describe the types and extent of plantar plate tears associated with increasing deformity of the second ray. We present, based on these findings, an anatomic grading system to describe the progressive anatomic changes in the plantar plate.

Abstract
PURPOSE To study the efficacy and safety of the combined plantar plate tenodesis and extensor digitorum brevis transfer in correction of claw toe deformity. METHODS Between 2007 and 2008, 11 patients (13 feet) underwent combined plantar plate tenodesis and EDB transfer for the correction of crossover second toe deformity. The clinical and radiological results were studied. RESULTS There was no more crossover toe deformity in all patients. Two patients had residual mild residual claw toe deformity. The lateral metatarsophalangeal angle in preoperative weight-bearing radiograph averaged 53° ± 5°. The postoperative lateral metatarsophalangeal angle averaged 23° ± 6°. The dorsoplantar metatarsophalangeal angle in preoperative weight-bearing radiograph averaged -9° ± 4°. The postoperative dorsoplantar metatarsophalangeal angle averaged 2° ± 4°. CONCLUSIONS Combined plantar plate tenodesis and extensor digitorum brevis transfer is an effective procedure to correct crossover second toe deformity. This is a relatively simple procedure and can be preformed through small incisions with minimal soft tissue dissection. LEVEL OF EVIDENCE Level 3 therapeutic study.

Abstract
The purpose of this study was to analyze the early results of a new technique for anatomic plantar plate repair and advancement using a Weil metatarsal osteotomy of the second metatarsal. The authors retrospectively reviewed medical records of 13 consecutive adult patients (15 feet) who underwent this procedure by a single surgeon. The authors recorded visual analog pain scale scores preoperatively and postoperatively and patient-reported clinical outcome measurement surveys during their final follow-up visit. At an average of 22.5 months (range, 13 to 33 months) follow-up, 11 of 13 patients (85%) reported improved function whereas 10 of 13 (77%) were either satisfied or very satisfied with the outcome. Postoperative scores on the American Orthopaedic Foot and Ankle Society Lesser Metatarsophalangeal- Interphalangeal Scale averaged 85.7 on a scale of 100 (SD = 13.1, 95% CI = 79.1-91.5). Patients reported an average preoperative visual analog pain scale of 7.3 (SD = 1.6, 95% CI = 6.4-8.1) versus an average of 1.7 (SD = 1.8, 95% CI = 0.7-2.7) postoperatively. This was a significant reduction in pain rating (P < .0001, t = 8.9, df = 27). Complications included painful hardware and metatarsalgia. There were no cases of dehiscence, malunion, nonunion, or recurrent metatarsophalangeal joint subluxation. This unique surgical technique addresses metatarsal overload and the instability of the second metatarsophalangeal joint while allowing for anatomic repair of the plantar plate pathology.

Abstract
BACKGROUND Instability of the second metatarsophalangeal (MTP) joint is relatively common, and although the anatomy of the joint has been well described and plantar plate pathology has been identified, little has been written about its exposure and repair. The goal of this study was to elucidate the necessary dissection to expose and potentially repair the lesions of the plantar plate through a dorsal approach. MATERIALS AND METHODS Sequential dorsal dissection of the second MTP joint was carried out in eight cadaveric specimens. After each step, measurements were obtained using fluoroscopic imaging and digital photography to determine the amount of exposure of the plantar plate gained by each step. RESULTS Dorsal capsulotomy of the second MTP joint with collateral ligament release off of the proximal phalanx base, then combined with a subcapital oblique metatarsal osteotomy provided on average 8 and 8.5 mm of exposure of the plantar plate as measured by digital photography and fluoroscopy, respectively. Minimal exposure was gained by releasing the collateral ligaments from the metatarsal head or elevating the plantar plate off of the plantar metatarsal head. CONCLUSION Exposure of the plantar plate can be obtained by releasing the collateral ligaments off of the proximal phalanx and performing a subcapital oblique osteotomy. CLINICAL RELEVANCE Minimizing the risk of disrupting the blood supply to the metatarsal head may be possible by avoiding collateral ligament or plantar plate release.

Abstract
Forefoot pain is one of the most common presenting problems in a foot and ankle practice. One of the most common presenting problems, yet most commonly missed problems, is a plantar plate tear. Often the problem is considered to be potential neuroma, fat pad atrophy, or a generalized diagnosis of metatarsalgia or metatarsal head overload. Unfortunately, not enough attention is placed on the plantar and medial/lateral ligamentous structures of the metatarsal-phalangeal joints. This lack of attention results in poor diagnosis, lack of care, treatment for the wrong condition, and ultimate frustration for the patients and doctor.

Abstract
BACKGROUND The purpose of the study was to evaluate the efficacy and safety of the modified plantar plate tenodesis for correction of claw toe deformity. MATERIALS AND METHODS Modified plantar plate tenodesis was performed in ten fresh frozen cadaveric feet with claw toe deformity of the second toe. The plantar plate of the second metatarsophalangeal joint was anchored to the extensor digitorum longus tendon by a figure-of-eight suture. The figure-of-eight construct and the relationship of the digital nerve and the suture were studied. A clinical study was conducted to study the operative times, degree of correction and the improvement of AOFAS score between groups with the original plantar plate tenodesis (Group 1) and modified technique (Group 2). Any neural injury if present was also noted. RESULT In the cadaveric study, the claw toe deformity was corrected and no nerve injury occurred in any specimen. There was flexor tendon tethering by the suture in 2 specimens. In the clinical study, the average operative time was 51 minutes for Group 1 and 31 minutes for Group 2. The improvement in AOFAS score averaged 44 in Group 1 and 43 in Group 2. The corrective power of the sagittal plane deformity at the metatarsophalangeal joint averaged 25 degrees in Group 1 and 23 degrees in Group 2. CONCLUSION Plantar plate tenodesis was effective in correction of flexible claw second toe deformity by stabilization of the attenuated plantar plate. The modified technique allowed easier retrieval of the suture and shorter operative time. However, it may result in tethering of the flexor tendon.

Abstract
The plantar plate provides a substantial static support for the lesser metatarsophalangeal joints. Insufficiency involving tear, attenuation, or absence of this structure can result in significant sagittal plane instability and deformity. When a plantar plate tear is established and is unresponsive to conservative treatment, plantar plate repair is indicated to address symptoms and reestablish static joint stability. The authors hypothesized that combined plantar plate and hammertoe repair with flexor digitorum longus tendon transfer provides a viable surgical option to address chronic plantar plate tears with secondary joint instability and digital deformity. The authors retrospectively evaluated a case series of 18 consecutive patients (20 feet) who underwent this combined surgical strategy as the primary procedure to address severe, chronic sagittal plane instability of the lesser metatarsophalangeal joints. Other procedures were performed concurrently in all cases to address predisposing factors and concomitant deformities. Method of evaluation included a subjective, objective, and radiologic evaluation performed at least 1 year after their surgical procedure. Two rating systems were used: the Lesser Metatarsophalangeal-Interphalangeal Scale from the American Orthopedic Foot and Ankle Society, and another designed by the authors. The average postoperative American Orthopedic Foot and Ankle Society score was 83.2/100 and the average postoperative score with the authors' rating system was 87.7/100. All patients were satisfied with their postoperative result. Study results suggest combined plantar plate and hammertoe repair with flexor digitorum longus tendon transfer to be a viable option to address severe, chronic sagittal plane instability of the internal lesser metatarsophalangeal joints. ACFAS Level of Clinical Evidence: 4.
