Juvara截骨联合软组织松解手术治疗中重度足拇外翻

目的评价Juvara截骨联合软组织松解术在治疗中重度足拇外翻手术的治疗效果。方法笔者自2014-02—2015-06对21例(25足)中重度足拇外翻行第1跖骨基底部Juvara截骨联合远端软组织松解(拇内收肌腱切断、籽骨悬韧带松解+内侧拇囊与骨赘切除)手术,术后采用美国足踝AOFAS评分与放射学检查评估。结果本组21例获平均11(5~16)个月随访,患者AOFAS评分由术前的平均58.03分提高到术后的93.81分。放射学检查:负重位足正侧位X线片示患者第1、2跖骨间夹角(IMA)与足拇外翻角(HVA)由术前的18.01°、38.62°降低到术后的平均7.93°与11.05°;第1跖骨头关节面外侧缘变成角形,关系稳定匹配。结论采用Juvara截骨联合远端软组织松解术治疗中、重度足拇外翻可以获得良好的临床效果,但足拇外翻应早发现、早治疗。     

The modified Ludloff osteotomy for correction of severe metatarsus primus varus with hallux valgus deformity

AIM: The present study investigates the clinical and radiological mid-term results of the modified Ludloff osteotomy, a proximal metatarsal osteotomy for surgical correction of severe metatarsus primus varus with hallux valgus deformity. METHOD: 70 feet in 67 patients from 25 to 78 years (average age 56 years) were included in this prospective study. The patients were evaluated with the American Orthopaedic Foot and Ankle Society (AOFAS) forefoot metatarsophalangeal interphalangeal score, which was used preoperatively and at an average follow-up of 37 +/- 6 months. Weight-bearing foot radiographs were analysed according to AOFAS guidelines and statistical evaluation was made with the Wilcoxon signed-rank test. RESULTS: The average AOFAS score improved significantly (p < 0.0001) from 55.2 +/- 15.2 points preoperatively to 86.6 +/- 15.2 points at follow-up. Preoperatively, all patients complained of pain (20.2 +/- 9.6 points) which had improved significantly (p < 0.0001) at the latest follow-up (37.3 +/- 5.7 points). The average hallux valgus angle (HVA) was 37 +/- 8 degrees preoperatively and improved significantly to 12 +/- 11 degrees at follow-up (p = 0.0001). The intermetatarsal angle (IMA) improved significantly from 18 +/- 2 degrees preoperatively to 8 degrees +/- 4 degrees after 37 +/- 6 months (p = 0.0002). The sesamoid position improved significantly from preoperative to follow-up (p = 0.0003). Radiographic evaluation of the patients indicated that all examined osteotomies had healed after 37 +/- 6 months. CONCLUSION: This prospective investigation at intermediate follow-up using currently available outcome measures suggests that the Ludloff osteotomy is a suitable procedure for the surgical correction of severe metatarsus primus varus (IMA > 15 degrees ) with hallux valgus deformity.

Correction of metatarsus primus varus associated with hallux valgus deformity using the arthrex mini tightrope: a report of 44 cases

Metatarsus primus varus must be addressed during correction of moderate to severe hallux valgus deformity. As an alternative to proximal osteotomy or first tarsometatarsal fusion for hallux valgus correction, this study presents a series of patients treated using the Arthrex Mini TightRope. A total of 36 patients (44 operations) with hallux valgus and metatarsus primus varus underwent correction using the Arthrex Mini TightRope. Assessment included measurement of radiographic parameters, the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot outcomes score, and the SF-12. The average hallux valgus angle improved from 32.2° to 15.2° (P < .0001). The average first intermetatarsal angle improved from 14.6° to 8.2° (P < .0001). The average distal metatarsal articular angle improved from 17.0° to 9.6° (P < .0001). The average AOFAS midfoot outcomes scores improved from 45.44 to 84.72 (P < .0001). Postoperative SF-12 physical and mental scores averaged 52.99 and 56.63. Only one patient had recurrence of deformity. Correcting metatarsus primus varus in association with hallux valgus deformity using the Arthrex Mini TightRope should be considered a treatment option. This technique is less invasive and seems capable of maintaining correction while allowing for early weight bearing and avoiding the need for a proximal first metatarsal osteotomy or Lapidus procedure.     

Hallux valgus and first ray mobility. A prospective study

BACKGROUND: There have been few prospective studies that have documented the outcome of surgical treatment of hallux valgus deformities. The purpose of this investigation was to evaluate the effect of operative treatment of hallux valgus with use of a proximal crescentic osteotomy and distal soft-tissue repair on the first metatarsophalangeal joint. METHODS: All adult patients in whom moderate or severe subluxated hallux valgus deformities had been treated with surgical repair between September 1999 and May 2002 were initially enrolled in the study. Those who had a hallux valgus deformity treated with a proximal crescentic osteotomy and distal soft-tissue reconstruction (and optional Akin phalangeal osteotomy) were then invited to return for a follow-up evaluation at a minimum of two years after surgery. Outcomes were assessed by a comparison of preoperative and postoperative pain and American Orthopaedic Foot and Ankle Society scores; objective measurements included ankle range of motion, Harris mat imprints, mobility of the first ray (assessed with use of a validated calibrated device), and radiographic angular measurements. RESULTS: Of the 108 patients (127 feet), five patients (five feet) were unavailable for follow-up, leaving 103 patients (122 feet) with a diagnosis of moderate or severe primary hallux valgus who returned for the final evaluation. The mean duration of follow-up after the surgical repair was twenty-seven months. The mean pain score improved from 6.5 points preoperatively to 1.1 points following surgery. The mean American Orthopaedic Foot and Ankle Society score improved from 57 points preoperatively to 91 points postoperatively. One hundred and fourteen feet (93%) were rated as having good or excellent results following surgery. Twenty-three feet demonstrated increased mobility of the first ray prior to surgery, and only two feet did so following the bunion surgery. The mean hallux valgus angle diminished from 30 degrees preoperatively to 10 degrees postoperatively, and the mean first-second intermetatarsal angle decreased from 14.5 degrees preoperatively to 5.4 degrees postoperatively. Plantar gapping at the first metatarsocuneiform joint was observed in the preoperative weight-bearing lateral radiographs of twenty-eight (23%) of 122 feet, and it had resolved in one-third (nine) of them after hallux valgus correction. Complications included recurrence in six feet. First ray mobility was not associated with plantar gapping. There was a correlation between preoperative mobility of the first ray and the preoperative hallux valgus (r = 0.178) and the first-second intermetatarsal angles (r = 0.181). No correlation was detected between restricted ankle dorsiflexion and the magnitude of the preoperative hallux valgus deformity, the post-operative hallux valgus deformity, or the magnitude of hallux valgus correction. CONCLUSIONS: A proximal crescentic osteotomy of the first metatarsal combined with distal soft-tissue realignment should be considered in the surgical management of moderate and severe subluxated hallux valgus deformities. First ray mobility was routinely reduced to a normal level without the need for an arthrodesis of the metatarsocuneiform joint. Plantar gapping is not a reliable radiographic indication of hypermobility of the first ray in the sagittal plane.     

Arthroscopy of the first metatarsophalangeal joint in 59 consecutive cases

The authors analyzed the results of 59 consecutive cases of the first metatarsophalangeal (MTP-I) joint arthroscopy to verify the efficacy and safety of the procedure. Fifty-nine patients were followed for >18 months after MTP-I joint arthroscopic procedures. The mean duration of follow-up was 25 months. Clinically, the American Orthopaedic Foot and Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal scale and the satisfaction of the patients were evaluated. Hallux valgus angle, the first intermetatarsal angle, and medial sesamoid position were analyzed in cases of hallux valgus. The American Orthopaedic Foot and Ankle Society hallux metatarsophalangeal-interphalangeal scale score was increased from 69 points preoperatively to 92 points postoperatively (p < .05). Radiologically, the mean hallux valgus angle was decreased from 29.2° preoperatively to 9.7° postoperatively (p < .05). The mean first intermetatarsal angle was decreased from 14.8° preoperatively to 7.7° postoperatively (p < .05). The medial sesamoid position was improved from 4.8 preoperatively to 2.0 postoperatively (p < .05). Ninety-five percent of the patients were satisfied with the procedures. There was 1 case of a wound problem and 1 case of temporary digital nerve injury as complications. Based on our experience, arthroscopy of MTP-I joint appears to be a safe and reproducible procedure for selected cases of MTP-I joint disorders.     

Three-Year Follow-Up Results of Combined Short Scarf Osteotomy With Akin Procedure for Hallux Valgus

The short scarf osteotomy has been developed as a less-invasive method of preserving the soft tissue envelope, at the same time maintaining the strength, correction, and utility of a classic long scarf osteotomy. We carried out a review of 166 short scarf osteotomies performed combined with the Akin procedure with a mean follow-up of 34.6 (range 28 to 38) months. These radiographic parameters were evaluated preoperatively, at 6 weeks, and at 3 years. The functional evaluation was based on the American Orthopaedic Foot and Ankle Society hallux metatarsophalangeal interphalangeal scale score. At follow-up, the mean American Orthopaedic Foot and Ankle Society hallux metatarsophalangeal interphalangeal scale score improved from a preoperative average of 54.6 to a postoperative average of 92.8 (p < .001). The radiographic evaluation gave the following results: the preoperative hallux valgus angle of 27.92° improved to an average of 11.85° (p < .001); the preoperative inter metatarsal angle of 14.03° improved to an average of 9.64° (p < .001). There were no fractures during the procedure. There were no incidences of infection or recurrence of deformity. Three patients have to undergo metatarsophalangeal joint fusion because of progression of osteoarthritis of the joint. No avascular necrosis of the metatarsal head was seen. The short scarf osteotomy along with Akin procedure is minimally invasive compared to the standard scarf osteotomy. It is a simple technique with good mechanical strength, signifying excellent patient satisfaction while reconstructing normal anatomy and restoring radiological measurements with fewer complications.     

Minimally Invasive Retrocapital Osteotomy of the First Metatarsal in Hallux Valgus Deformity

OBJECTIVE: Percutaneous retrocapital distal osteotomy of the first metatarsal for surgical treatment of hallux valgus. INDICATIONS: Mild to moderate hallux valgus deformity in both juveniles and adults. Recurrent hallux valgus deformity after previous surgery. CONTRAINDICATIONS: Severe degenerative changes of the first metatarsophalangeal joint (hallux valgus et rigidus). Previous Keller's procedure. SURGICAL TECHNIQUE: A percutaneous distal linear osteotomy of the first metatarsal is performed and stabilized with a Kirschner wire. The surgical technique follows these steps: distal Kirschner wire insertion; skin incision; sparse periosteal detachment; distal retrocapital osteotomy of the first metatarsal; correction of the first intermetatarsal angle by lateral displacement of the capital fragment; stabilization with Kischner wire insertion into the proximal metatarsal; postoperative taping. RESULTS: The patients were satisfied following 107 (91%) of 118 consecutive percutaneous procedures with a follow-up of 35.9 months (range 24-78 months). According to the American Orthopaedic Foot and Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal scale for the clinical assessment, a mean score of 88.2 +/- 12.9 was obtained at follow-up. The clinical results can be compared to those obtained with open techniques, with the advantages of a minimally invasive procedure.     

The Spike Osteotomy for Hallux Valgus: A Clinical and Radiological Evaluation

A distal metatarsal osteotomy with soft tissue correction is a frequently performed operation to correct mild to moderate hallux valgus deformity. This is a prospective study of 28 feet in 25 patients who underwent spike osteotomy of the first metatarsal with medial capsulorraphy for symptomatic hallux valgus. The osteotomy is a distal metatarsal osteotomy with a spike fashioned in the plantar and lateral quarter of the proximal fragment and impacted into the trough created in the center of the distal fragment, providing lateral and plantar shift of the distal fragment. The American Orthopaedic Foot and Ankle Society's rating scale was used for functional assessment, and a visual analog scale gauged pain. The average follow-up was 27 months. The rating scale score improved from a mean preoperative value of 39/100 to 84/100. Twenty-six feet had complete pain relief, whereas 2 feet had a lesser degree of persistent metatarsalgia. A review of preoperative and postoperative radiographs showed that the hallux valgus angle improved from a mean 36 degrees preoperatively to 18 degrees postoperatively. Likewise, the mean 1 to 2 intermetatarsal angle improved from 13 degrees to 7.3 degrees. There was no incidence of avascular necrosis. Fourteen patients (16 feet) rated the outcome as excellent, 10 (11 feet) as good, and 1 patient with asymptomatic mild hallux varus deformity rated the result as fair. These results demonstrate that the spike osteotomy is a suitable operation for treatment of mild to moderate hallux valgus.     

Treating Hallux Valgus Associated Metatarsus Adductus by Minimally Invasive Surgery: A Simple Solution for a Difficult Problem

This study aims to assess a novel minimally invasive surgical technique that addresses hallux valgus accompanied by metatarsus adductus.We retrospectively analysed the results of 20 patients (21 feet) that underwent a newly developed percutaneous osteotomy procedure of the lesser metatarsal bones in order to correct hallux valgus deformities accompanied by metatarsus adductus. We used x-ray studies in order to evaluate changes in the hallux valgus angle, the first intermetatarsal angle, and the metatarsal angle (using the modified Sgarlato method). We also compared the pre- and postoperative American Orthopaedic Foot and Ankle Society scores when available. The paired sample t test was used to compare variables.At a 1-y follow-up the mean hallux valgus angle, inter-metatarsal angle and the metatarsal angle have been reduced by 31.62 (-3 to 9), 3.86 (11-52) and 14.69 (4-36) respectively (p < .001 for all). The mean American Orthopaedic Foot and Ankle Society score (n = 15 feet available) has been improved by a mean of 44.53 (22-72, p < .001). In addition, the patient satisfaction rates were high. Patients suffered from mild to moderate midfoot pain during the first few weeks following surgery, which resolved when union occurred. No cases of lesser metatarsal nonunion have been documented.The presented minimally invasive method can be used effectively to correct hallux valgus that is associated with metatarsus adductus. Proximal minimally invasive metatarsal osteotomy can effectively correct hallux valgus accompanied by metatarsus adductus.     

A modified Austin/chevron osteotomy for treatment of hallux valgus and hallux rigidus

Abstract

The purpose of this brief paper is to present the preliminary results of a modified Austin/chevron osteotomy for treatment of hallux valgus and hallux rigidus. In this procedure, the dorsal arm of the osteotomy is performed orthogonal to the horizontal plane of the first metatarsal, the main advantage being that this allows much easier and more accurate multiplanar correction of first metatarsal deformities. From 2010 to 2013, 184 consecutive patients with symptomatic hallux valgus and 48 patients with hallux rigidus without severe metatarsophalangeal joint degeneration underwent such modified chevron osteotomy. Mean patient age was 54.9 (range 21–70) years, and mean follow-up duration was 41.7 (range 24–56) months. Ninety-three percent of patients were satisfied with the surgery. Mean American Orthopaedic Foot and Ankle Society (AOFAS) score improved from 56.6 preoperatively to 90.6 at last follow-up, and mean visual analog scale (VAS) pain score decreased from 5.7 preoperatively to 1.6 at final follow-up (p < 0.05). In patients treated for hallux valgus, mean hallux valgus angle decreased from 34.1° preoperatively to 6.2° at final follow-up, and mean intermetatarsal angle decreased from 18.5° preoperatively to 4.1° at final follow-up (p < 0.05). One patient developed postoperative transfer metatarsalgia, treated successfully with second-time percutaneous osteotomy of the minor metatarsals, whilst one patient had wound infection that resolved with systemic antibiotics.
