Distal metatarsal osteotomy for hallux valgus in the middle-aged patient.

Thirty-eight distal metatarsal osteotomies for hallux valgus in middle-aged patients between the ages of 50 and 67 years were performed over a period of five years. None of the patients could be rated with an excellent result. Good results were noted in only 52.6%. Poor results were attributable to imperfect surgical technique, severity of preoperative deformity, osteoporosis, and preexisting osteoarthritic changes at the first metatarsophalangeal joint.

Surgery for adolescent hallux valgus.

Attention is directed to the large number of operations for the correction of hallux valgus in the adolescent and important variations among the most popular surgical procedures, as well as the factors influencing the outcome of these operations. A consistently reliable operation is the modified Wilson procedure, a metatarsal shaft osteotomy. Its merits are its technical simplicity, minimal damage to soft tissue, and pleasing correction of deformity. The operation narrows the forefoot, relaxes soft tissues, and maintains excellent mobility of the first metatarsophalangeal joint.

The distal metatarsal osteotomy for the treatment of hallux valgus.

This article discusses various forms of distal metatarsal osteotomy for the treatment of hallux valgus. The techniques for the various osteotomies have evolved over the years to allow the surgeon to match a procedure and its modifications to the individual patient's deformity, thus optimizing outcomes. Fixation techniques continue to evolve, and meticulous surgical technique to prevent complications remains a must. Regardless of the osteotomy used, the authors believe that adherence to the techniques laid out in current literature will provide gratifying results for the surgeon and the patient.

Mathematical model for pre-operative planning of linear and closing-wedge metatarsal osteotomies for the correction of hallux valgus.

First-metatarsal osteotomy is performed for an abnormal intermetatarsal angle and severe hallux valgus deformity. The metatarsal head is slid along the osteotomy and fixed with a Kirschner wire to achieve angular and linear realignment with respect to the other metatarsals. When reduction of joint subluxation is also sought, a bone wedge is removed. A mathematical model and a corresponding computer-based tool were developed for pre-operative planning of the optimum surgical solution. Standard intermetatarsal angle correction, head-to-sesamoids re-alignment, joint subluxation reduction and metatarsal length adjustment were all pursued. A standard pre-surgical dorso-plantar radiograph of the patient, with an additional metal ball for calculation of X-ray magnification, was necessary to analyse the original and final geometrical configurations. For the first time, expected bone loss and wire diameter were also considered. The angles of bone cuts and the amount of sliding along these cuts were calculated by the model according to the surgical goal. All the resulting geometrical parameters, both in the pre- and planned post- operative configuration, were provided in graphical and tabular form. In a change from former qualitative analysis of radiograms, the surgeon can now enter the operating theatre with a detailed plan of the goal to be achieved.

[Recurrent hallux valgus treated with metatarsophalangeal arthrodesis. A series of 32 patients].

PURPOSE OF THE STUDY: We reviewed a series of 32 cases of recurrent hallux valgus treated by great toe metatarsophalangeal arthrodesis with a minimal 5-year follow-up. MATERIAL AND METHOD: Mean delay from the first surgical procedure and revision surgery was 11 years. All patients complained of forefoot pain. The average angle of the phalangeal valgus was 39 degrees. Sixteen patients had metatarsalgia. The first toe metatarsophalangeal joint was evaluated according to Regnauld's classification: two grade 1, eight grade 2a, six grade 2b, sixteen grade 3. Arthrodesis was fixed with an axial screw and associated with adductor hallux plasty. Outcome was assessed at a minimum 5-year follow-up according to Kitaoka's criteria. RESULTS: Seventy-eight percent of the patients were pain free at last follow-up. Valgus deviation of the great toe was corrected with an average angle of 19 degrees. The arthodesis healed in 90.6% of the cases. Statistical analysis showed the importance of great toe valgus pre- and postoperatively and at last assessment. Final outcome was poor in the oldest patients. The overall outcome was rated good in 84% of the cases, average in 6% and poor in 10%. DISCUSSION: Arthrodesis of the great toe is not a disabling surgery. Interphalangeal osteoarthritis may occur due to joint overuse (12 cases). Kitaoka's series compared outcome after arthrodesis with that after conservative surgery and reported better results with arthrodesis. Revision surgery for hallux valgus using great toe metatarsophalangeal arthrodesis remains an acceptable alternative.

Crescentic proximal metatarsal osteotomy for moderate to severe hallux valgus: a mean 12.2 year follow-up study.

The senior author's (R.C.) first 25 patients (37 feet) treated with a combination proximal crescentic osteotomy and distal soft-tissue reconstruction made up the patient cohort. All 25 patients were reviewed at a minimum of one year post-op (short-term follow-up) and 20/25 (31/37 feet) were reviewed again at a mean 12.2 years (range 11.4 to 13.0 yrs) post-op (long-term follow-up). This allowed for a comparison of short- and long-term results and led to a long-term follow-up rate of 84% (31/37 feet, mean 12.2 yrs). Clinical, radiographic and patient outcome measures were obtained and compared pre-op and at short- and long-term follow-up. The mean preoperative hallux valgus (HVA) and intermetatarsal angles (IMA) were 37degrees and 16 degrees respectively. The mean HVA correction was 24 degrees and IMA correction 10 degrees at long-term follow-up with no tendency toward recurrence. Sesamoid position and first MTP subluxation was markedly improved postoperatively and the correction was maintained at long-term follow-up. Patients were asked about their satisfaction in terms of pain, appearance and motion. At long-term follow-up, more than 90% of patients were completely satisfied with pain and motion and greater than 80% with their appearance. Ninety-four percent of patients said they would have the operation again. The AOFAS clinical rating scale for the hallux was calculated retrospectively for pre-op and short-term follow-up and prospectively for long-term follow-up. The mean pre-op score was 37/100 (16 to 60) which significantly improved to 92/100 (67 to 100) at both follow-up periods, suggesting no evidence of decrease in outcome over time. Complications included two patients (5%) that were over-corrected into varus (one symptomatic, one asymptomatic), and four patients (11%) that were undercorrected, developing asymptomatic recurrences (>10 degrees increase HVA) at long-term follow-up. In addition, two patients (5%) developed new transfer lesions postoperatively, likely related to technical error (one varus overcorrection, one dorsiflexion malunion). In conclusion, the long-term results, with a mean follow-up of 12.2 years, of the resection realignment procedure for moderate to severe hallux valgus are generally excellent and the complication rate is low and acceptable. Attention to detail, avoiding both undercorrection, which can lead to recurrence, and overcorrection, which can cause symptomatic varus, is essential.
