Metatarsus adductus and selected radiographic measurements of the first ray in normal feet.

Radiographic evaluation of hallux abducto valgus frequently involves the measurement of the metatarsus adductus angle, first-second intermetatarsal angle, hallux abductus angle, and proximal articular set angle. While the concept that there is a relationship between untreated metatarsus adductus and hallux abducto valgus deformity is not new, a quantifiable relationship between the metatarsus adductus angle and intermetatarsal angle, hallux abductus angle, and the proximal articular set angle in normal feet is relatively undocumented. The purpose of this study is to document relationships between the metatarsus adductus angle and the other three measurements, and to establish normal values for the intermetatarsal angle, hallux abductus angle, and proximal articular set angle within metatarsus adductus angle subgroups.

Congenital metatarsus varus. A suggestion for a possible mechanism and relation to other foot deformities.

The pathogenesis of metatarsus varus was investigated by a series of dissections of 14 normal feet of stillborn or infants who died during the perinatal period. The deformity could not be produced without the surgical incisions described below. A valgus position of the hindfoot was produced by maximal dorsiflexion of the foot. The deformity of the fore part of the foot could not be produced even by extreme traction on the tibialis anterior tendon even after capsulotomy of the first tarsometatarsal joint. Only extensive capsulotomies in the tarsometatarsal joints distal to the joint of Chopart made it possible to displace the bones into the position analogous to metatarsus varus. It is suggested that metatarsus varus may be a deformity which occurs on a maximally dorsiflexed foot and that the primary mechanism of the forefoot deformity is a subluxation in the fore part of the foot. Secondary contractures of the soft tissues, and adaptive bone changes offer a possible explanation for lack of spontaneous recovery as well as the difficulties encountered in treating late cases.

A new surgical technique for metatarsus primus varus correction with radical bunionectomy: a preliminary report.

Dr. Panacos has developed a new surgical technique for correction of metatarsus primus varus. His technique, which is indicated in moderate to severe metatarsus primus varus (when the intermetatarsal angle exceeds 15 degrees), makes use of a stabilizing implant at the first metatarsal-cuneiform joint. Although the procedure has been performed on a limited number of patients, the author believes it to be superior to the osteotomy for metatarsus primus varus correction.

[Initial experience with the closed method of subcapital osteotomy of the 1st metatarsus in hallux valgus].

The authors summarize initial findings with Bösh's modification of Hohmann's subcapital osteotomy made by means of a cutter from a short dermal incision under X-ray control. The valgosity and rotation of the hallux are corrected by a lateral and possibly plantar shift and by derotation of the head of the metatarsus. The position of the head is ensured by supporting the medial exostosis by a wire inserted by the intramedullary route into the Ist metatarsus. The operation was performed in five female patients aged 37-60 years on nine feet. The results were evaluated after 10-13 months. For osteotomy conic cutters were used (diameter of base 2.1 mm and 5 mm) and a drill (3000 rotations per minute) from the small instrumentarium of SYNTHES Co. The Kirschner wire was removed after four weeks and fixation a with a plaster spica of the toe took, depending on healing, 7-12 weeks after operation. In all instances marked correction of the position of the toe occurred (reduction of the valgosity angle by 8-19 degrees). As to subjective evaluation, four patients evaluated the result as excellent, three as satisfactory, i.e. disappearance or marked reduction of complains and once as unsatisfactory with persisting pain and difficulties as regards footwear. After analysis of the first early results the authors recommend to indicate the operation in valgosity of the toe up to 35 degrees and minimal arthrosis, to perform the osteotomy in a strictly subcapital and extracapsular position and to reduce the period of fixation. The advantage of the method is that the metatarsophalangeal joint is not damaged, the operation is sparing, marked correction of the position of the toes is achieved, the time of operation is short and the scar is not visible.

Metatarsus primus varus. A statistical study.

A survey of 6000 schoolchildren discovered 36 cases of unilateral and 60 cases of bilateral hallux valgus, defined as a metatarsophalangeal angle of more than 14.5 degrees, measured on standing radiographs. Metatarsus primus varus was found not only in the early stages of hallux valgus but in the unaffected feet of children with unilateral hallux valgus. Adduction of the first metatarsal is not due to differential growth of the cortices of the first metatarsal nor is it a consequence of malalignment of the metatarsocuneiform joint. The intermetatarsal angle did not correlate with the angle of metatarsus adductus nor with the intercuneiform angle.

Metatarsus varus corrected by open wedge osteotomy of the first cuneiform bone.

The persistence of metatarsus adductus varus has been a problem in management. We have treated a series of selected patients with this problem and believe that our results have been better than with the procedure we have used in the past. Fowler has described a procedure which seems ideal for the patients in our series. Through personal communication the procedure and its application were discussed and the series was started eight years ago. Our series is small because our patients are responding to other forms of treatment at an earlier age. The few that do not respond are now considered for the operation described. The procedure is relatively simple to perform. Full correction should be obtained at the time of surgery. Casting is utilized to hold the correction and immobilize the extremity for healing. Our unsatisfactory results occurred because of errors in technique or poor selection of patients. We believe that this procedure should be considered in the older patient with metatarsus varus.

Syndrome of microcephaly, Brachmann-de Lange-like facial changes, severe metatarsus adductus, and developmental delay: mild Brachmann-de Lange syndrome?

We report on 4 individuals (3 sibs and their father) with a syndrome of growth retardation, microcephaly, minor facial anomalies reminiscent of a mild Brachmann-de Lange syndrome (BDLS), severe metatarsus adductus, developmental delay, and unusual dermatoglyphics. The syndrome, which seems to be inherited as an autosomal dominant trait with variable expressivity, resembles mild BDLS.

Rheumatoid metatarsus. The original evolution of the first metatarsal.

Three hundred and eight unselected rheumatoid feet underwent a weight-bearing X-ray examination. If the malformations of the forefoot studied here present a statistical association, the primus metatarsus adductus is closely connected with tarsal arthritis and flattened foot but does not depend on the duration of the disease. The spread forefoot is indeed related to the duration of the disease and the presence of a metatarsal erosion at the foot level, but is not affected by the lesions of the midfoot. It appears then that an early orthopaedic treatment should be prescribed, once the first signs of involvement of the first ray or pronounced pronation of the hindfoot are noticed; it must affect the hindfoot, the midfoot and the first ray which progress together.

Section of the abductor hallucis tendon for correction of metatarsus varus deformity.

Section of the abductor hallucis tendon is recommended for early correction of the metatarsus adductus deformity especially in the residual of a treated equinovarus foot. The operation is simple and safe, with very little postoperative morbidity. The effectiveness of the procedure is enhanced if a tight abductor hallucis tendon is demonstrated. The operation may also be helpful in conjunction with other surgical procedures for correction of the varus deformity of a clubfoot.

Hallux valgus and metatarsus primus varus treated by bunionectomy and proximal metatarsal osteotomy.

Sixteen feet with hallux valgus and metatarsus primus varus have been treated by excision of the exostosis of the first metatarsal head, advancement of the medial capsule and the abductor hallucis, release of the lateral capsule and adductor tendon, and open-wedge osteotomy at the base of the first metatarsal inserting a bone graft. During a three-year period ther have been no nonunions of the osteotomy, and satisfactory maintenance of the corrections has occurred. This method is preferred over distal metatarsal osteotomy.

Anomalous insertion of the tibialis posterior tendon in congenital metatarsus varus.

Congenital metatarsus varus is a common deformity that usually responds to conservative treatment. In fifteen feet operated on for resistant deformity, an anomalous insertion of the tibialis posterior tendon was found in fourteen. Six cadaveric infant feet were dissected to confirm the normal insertion. The dynamic component of the deformity is stressed.

Congenital metatarsus varus. On the advantages of early treatment.

Among 212 infants with congenital metatarsus varus 84 (39.6 per cent) of the infants were treated. Only the treated group is considered in the analysis. Daily manipulative therapy was given followed by fixation in elastic bandage or splint. The manipulations aimed at correcting the adduction of the fore part of the foot, as well as the increased valgus of the heel. In 68 infants treatment was instituted before one year of age. The results were good in 65 of these patients and correspondingly good results were obtained in 15 out of 16 patients treated at more than one year of age. Subluxation in the fore- and midfoot and bony incongruity present at birth are offered as a possible explanation for lack of spontaneous recovery before weightbearing as well as the occurrence of resistant cases. Spontaneous improvement may take place during childhood and may be explained by the influence of the position of the heel during weightbearing.

Juvenile hallux valgus with compensated metatarsus adductus. Case report.

The authors describe a case report of a patient with compensated metatarsus adductus and juvenile hallux valgus bilaterally. Treatment included closing base wedge abductory osteotomies of metatarsals one through five, modified McBride bunionectomy, Evans calcaneal osteotomy, and a percutaneous tendo Achillis lengthening. The patient maintained excellent correction on the right foot after 6 years. Hallux valgus recurred on the left foot after 2 years. The authors attribute this recurrence to a significant internal femoral torsion on the left leg. The significance of superstructural deformities on juvenile hallux valgus is discussed.

Procedures to correct hallux abducto valgus and metatarsus primus adductus.

Four procedures are presented to correct hallux abducto valgus and metatarsus primus adductus in the child between the ages of 3 and 7 years. A new procedure is introduced: a subtalar extra-articular lateral arthroereisis, and an erasure procedure of the epiphysis is discussed. An important new concept in pediatric podiatry is introduced: it is often possible to prevent major surgery in the adult by performing a minor procedure in the young child. Finally, a Reverdin's procedure to correct the articular set angle in adults is presented.

Structural metatarsus adductus deformity, surgical case report.

Structural metatarsus adductus deformity may be corrected through the use of closing abductory base wedge osteotomies of all five metatarsals. Although technically demanding, surgical precision is increased through the use of oblique wedges and a combination of screw and cerclage wire fixation. In the severe case, an opening wedge osteotomy of the inner cuneiform (Fowler procedure), with homogenous bone implantation, may be concomitantly used. Both techniques are described in this brief case presentation.

Observer variability in the radiographic measurement and classification of metatarsus adductus.

The classification system of Berg was evaluated using four observers and the radiographs of 42 feet from patients with metatarsus adductus. Interobserver disagreement in diagnosis was 36%. Intraobserver inconsistency averaged 26%. The error range for the lateral and anteroposterior talocalcaneal angle measurement was 13.6 and 15.1 degrees intraobserver and 19.8 and 25.2 degrees interobserver, respectively. There was no correlation between classification and the length of time required for cast correction. The irregularity of hindfoot ossification centers makes measurements inconsistent and seriously reduces the usefulness of classification based on such measurements.

Simple method of documenting metatarsus adductus.

A simple, accurate, and inexpensive method of documenting metatarsus adductus involves taking photocopies of the foot in the weightbearing position. Subsequently, treatment progress can be assessed objectively by reviewing serial photocopies. Some caution is urged because the strength of the glass copying surface of photocopying machines is unknown.
