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.

The chevron osteotomy for correction of hallux valgus

Introduction The chevron osteotomy has become widely accepted for correction of mild and moderate hallux valgus deformities. The purpose of this study was to present the evolution of the chevron osteotomy at one institution over a period of 12 years. Methods Between April, 1991 and September, 1992, fifty-two consecutive patients with mild to moderate hallux valgus deformity underwent sixty-six distal chevron osteotomies at our institution. This was followed by 85 patients with 100 feet in the period from 1992 to 1995 and a group of 45 patients with 55 feet from 1994 to 1995. The final patient group included 61 patients with 89 feet operated from 2000 to 2002. Conclusion The chevron osteotomy is a reliable technique to correct hallux valgus deformities. Our recommendation after reviewing the results of the various modifications of the chevron technique revealed that the addition of a lateral release and a screw fixation will lead to the most reliable results.

Percutaneous distal metatarsal osteotomy for correction of hallux valgus

BACKGROUND: Distal osteotomy of the first metatarsal is indicated for the surgical treatment of mild-to-moderate hallux valgus deformity. The aim of this study was to evaluate the results of a subcapital distal osteotomy of the first metatarsal with use of a percutaneous technique. METHODS: From 1996 to 2001, 118 consecutive percutaneous distal osteotomies of the first metatarsal were performed for the treatment of painful mild-to-moderate hallux valgus in eighty-two patients. The patients were assessed with a clinical and radiographic protocol at a mean of 35.9 months postoperatively. The American Orthopaedic Foot and Ankle Society (AOFAS) hallux-metatarsophalangeal-interphalangeal scale was used for the clinical assessment. RESULTS: The patients were satisfied following 107 (91%) of the 118 procedures. The mean score on the AOFAS scale was 88.2 +/- 12.9 points. The postoperative radiographic assessments showed a significant change (p < 0.05), compared with the preoperative values, in the mean hallux valgus angle, first intermetatarsal angle, distal metatarsal articular angle, and sesamoid position. The valgus deformity recurred after three procedures (2.5%), the first metatarsophalangeal joint was stiff but not painful after eight (6.8%), and a deep infection developed after one (0.8%). The infection resolved with antibiotic therapy. CONCLUSIONS: The percutaneous technique proved to be reliable for the correct execution of a distal linear osteotomy of the first metatarsal for the correction of a painful mild-to-moderate hallux valgus deformity. The clinical results appear to be comparable with those obtainable with traditional open techniques, with the additional advantages of a minimally invasive procedure, a substantially shorter operating time, and a reduced risk of complications related to surgical exposure.     

Clinical results of modified Mitchell's osteotomy for hallux valgus augmented with oblique lesser metatarsal osteotomy

PURPOSE: To evaluate postoperative results of modified Mitchell's osteotomy and its combination with oblique metatarsal osteotomy for the treatment of hallux valgus. METHODS: A total of 93 feet of 53 patients (2 men and 51 women) with hallux valgus underwent modified Mitchell's osteotomy and were followed up for at least 5 years. Patients' age ranged from 17 to 83 years, and the duration of follow-up ranged from 5 years one month to 18 years 4 months. Modified Mitchell's osteotomy was performed on 53 feet in 31 patients (group A), whereas modified Mitchell's osteotomy augmented with oblique lesser metatarsal osteotomy was performed to the remaining 40 feet in 22 patients (group B). Postoperative results were assessed using a clinical assessment system developed by the Tokyo Medical University based on 5 categories: pain in the first metatarsophalangeal, deformity of the metatarsophalangeal, plantar callosity and/or metatarsalgia of lesser metatarsals, the use of commercially available shoes, and local inflammatory symptoms. RESULTS: Mean total score improved from 3.8 to 7.9 on a 10-point scale. Scores for 2 categories--plantar callosity and/or metatarsalgia and the use commercially available shoes--were significantly higher in group B at postoperative 5 years. Before surgery, at postoperative 3 weeks, and at postoperative 5 years, respectively, the mean hallux valgus angles were 34.2, 12.0, and 17.1 degrees; mean M1-M2 angles were 16.7, 7.4, and 8.7 degrees; mean M1-M5 angles were 34.9, 25.8, and 26.6 degrees; and mean sesamoid bone shifts were 8.7 mm, 4.3 mm, and 5.9 mm. CONCLUSION: Modified Mitchell's osteotomy shortens the length of the first metatarsal bone and thus relieves tension in soft tissues such as the adductor hallucis. Nonetheless, the procedure can induce metatarsophalangeal joint malalignment and metatarsalgia, and plantar callosity may develop or persist after surgery. Combining oblique metatarsal osteotomy of the lesser metatarsal bones is useful in patients with uneven metatarsal bone lengths and metatarsophalangeal joint malalignment.     

Radiographic results after percutaneous distal metatarsal osteotomy for correction of hallux valgus deformity

BACKGROUND: The goal of the study was to evaluate the short-term radiographic results and complications of a percutaneous distal metatarsal osteotomy for hallux valgus. METHODS: From June, 2005, until October, 2005, a percutaneous distal first metatarsal osteotomy was performed in 13 consecutive patients. All patients had mild to moderate hallux valgus deformities preoperatively. The mean postoperative followup was 130 (range 50 to 207) days. The radiographs were reviewed for hallux valgus angle, 1-2 intermetatarsal angle, nonunion, malunion, and osteonecrosis. RESULTS: The mean 2 weeks postoperative hallux valgus angle demonstrated a statistically significant (p < 0.0001) improvement from 25 (16 to 33) degrees preoperatively to 5 (-1 to 12) degrees postoperatively. Nine patients (69%) demonstrated dorsally angulated alignment of the first metatarsal at the first postoperative examination averaging 10.8 (6 to 15) degrees that increased to 15.9 (10 to 22) degrees at final followup. One patient developed cystic changes within the metatarsal head consistent with osteonecrosis. One patient developed a nonunion with no evidence of radiographic healing at most recent followup of 180 days. Five patients (38%) had recurrent hallux valgus defined as a final angle of greater than 15 degrees. CONCLUSIONS: Percutaneous distal metatarsal osteotomy for hallux valgus is associated with an unacceptable rate of complications, specifically, osteonecrosis, nonunion, malunion, and recurrence. The intraoperative correction was routinely lost after removal of the intramedullary Kirschner wire, leading to a high rate of recurrence of hallux valgus deformity as well as dorsal elevation of the capital fragment.     

The SCARF osteotomy for the correction of hallux valgus deformities

The authors report their experience with a modified SCARF osteotomy with three years follow-up. Correction of moderate to severe hallux valgus deformities was achieved using a Z step osteotomy cut to realign the first metatarsal bone. A retrospective analysis was undertaken in 89 consecutive patients (111 feet). Results were analyzed by clinical examination, a questionnaire including the AOFAS forefoot score, and plain roentgenograms. Hallux valgus and intermetatarsal angle improved at mean 19.1 degrees and 6.6 degrees, respectively. Mean forefoot score improved from 50.1 to 91 points out of 100 possible points. Satisfactory healing time was expressed by an average return back to work of 5.8 weeks and back to sport of 8.3 weeks. Persistence or recurrence of hallux valgus was seen in seven patients (6%). The complication rate was 5.4% including superficial wound infection, traumatic dislocation of the distal fragment, and hallux limitus. The presented technique provides predictable correction of moderate to severe hallux valgus deformities.     

Distal osteotomy for bunionectomy and hallux valgus correction.

Distal osteotomies are the original osteotomies performed in the first metatarsal for bunion surgery. Many of these can be fashioned to improve an abnormal DMAA. Correction of an abnormally wide first-second IM angle is a goal of the newer procedures. Lateral transposition at the osteotomy site first performed by Mitchell helps accomplish this goal. The chevron modification improves stability and offers sufficient correction for mild-to-moderate deformities. Fixation is recommended after metatarsal osteotomy. The distal chevron procedure has been associated with lower degrees of correction, but the risk of transfer metatarsalgia is minimized. Shortening is less likely compared with some distal osteotomies but can occur. Advanced age is not a contraindication for distal metatarsal osteotomy. Avascular necrosis is highly unusual after this procedure.     

Late results after correction of hallux valgus deformity by basilar phalangeal osteotomy

In a long-term follow-up study (average, 10.7 years) of 222 patients (351 feet), the results after proximal phalangeal osteotomy (the Akin procedure) for hallux valgus deformity were found to be unsatisfactory, both subjectively and objectively. The range of motion in the metatarsophalangeal joint was limited postoperatively in 90 per cent of the patients, and in 21 per cent there was recurrence of deformity. The appearance of the foot was poor in 75 per cent. Only 53 per cent of the patients expressed satisfaction with the result of the operation. There was a direct relationship between the development of subluxation or dislocation of the metatarsophalangeal joint and postoperative dissatisfaction of the patient. We concluded that the operation is biomechanically unsound because it does not address the principal mechanical factors that are responsible for the deformity: abnormal function of the adductor hallucis and the abnormal intermetatarsal angle. The Akin procedure is indicated only in combination with other operations that are designed to correct the two cited abnormalities.     

Early outcome of correction of hallux valgus with the Scarf osteotomy

INTRODUCTION: Aim of this study is to analyze complications as well as clinical and radiological results of the scarf osteotomy for the correction of hallux valgus. PATIENTS AND METHODS: Between 1994 and 1998 we performed a scarf osteotomy for the correction of hallux valgus in 45 cases. Indication was a symptomatic hallux valgus with an increased first intermetatarsal angle (IMA). Fixation of the osteotomy was performed with two 2.3 mm mini screws made of titaneum. Mobilisation was allowed with full weight bearing with a fore foot relief orthesis. Clinical results were valued with the fore foot scoring system (ffss). The determination of the IMA and hallux valgus angles (HVA) was performed with weight bearing d.p. radiographs. RESULTS: All osteotomies healed within the first 6 postoperative weeks. Removal of the screws was not necessary in any case. The preoperative ffss was 16.2 points. At the last follow up (16 month after surgery) the average value of the ffss was 59.1 points. Three patients reached a value below 35 points, two of them suffered from a rheumatic disease. Twenty patients assessed the cosmetic result as excellent, 16 as good, 4 as satisfactory and one as poor. The average IMA could be reduced significantly from 20.2 to 10.3 degrees. The HVA could be lowered from 37.5 to 20.9 degrees. In patients with an IMA of more than 20 degrees the HVA could be reduced to 23.1 degrees in contrast to 18.3 in patients with an IMA of less than 20 degrees. DISCUSSION: The scarf osteotomiy is a surgical procedure for the correction of hallux valgus due to increased IMA which is appropriate in patients younger than 50 years and older than 50 years. In cases of IMA more than 20 degrees correction of IMA and HVA was unsatisfactory.     

Chevron osteotomy versus scarf osteotomy for hallux valgus correction: A meta-analysis

BackgroundThis study intended to investigate the optimal surgical strategy in hallux valgus (HV), and to provide a basis for clinical treatment of HV.MethodsStudies related to chevron osteotomy and scarf osteotomy for HV were enrolled from online databases. Hallux valgus angle (HVA) was the main outcome variable. Enrolled studies included posttreatment data for intermetatarsal angle (IMA), American Orthopaedic Foot & Ankle Society (AOFAS) score, and complications. A random-effects model was applied for significant heterogeneity. Otherwise, a fixed-effects model was used. Heterogeneity was assessed with Q test and I² statistics. Publication bias was evaluated with Egger's test. Based on the influence of weighted mean difference values or odds ratios, a sensitivity analysis was performed.ResultsFour studies including 384 subjects were evaluated to determine the optimal surgical strategy for HV. There was no statistically significant difference between chevron and scarf groups for HVA, IMA, AOFAS score, and complication rates. Sensitivity analysis showed good stability. The likelihood of publication bias was small.ConclusionThe effects of chevron osteotomy and scarf osteotomy for HV are comparable. Chevron osteotomy is less technically demanding.
