Roentgenologic findings of the hydrolethalus syndrome.

The hydrolethalus syndrome is an autosomal recessive malformation syndrome which has been recently described in Finland. The name hydrolethalus refers to the main findings, namely polyhydramnios, hydrocephalus and lethality. The patients are either stillborn or die soon after birth. The typical roentgenologic findings are hypoplasia of the tibia associated with the anomalies of the respective bone ray, e.g. metatarsus primus varus atavisticus, hallux varus or hallux duplex varus and hydrocephalus with extreme micrognathia and a specific midline defect of the occipital bone.

The modified Lapidus procedure for hallux valgus: a clinical and radiographic analysis.

BACKGROUND: Historically, the modified Lapidus procedure has been considered technically challenging, with high rates of complications, including nonunion and malunion. The purpose of this study was to review the clinical and radiographic results of this technique for the treatment of hallux valgus associated with first ray hypermobility, specifically examining patient satisfaction and the incidence of complications. METHODS: We retrospectively reviewed the results of the modified Lapidus procedure in 32 patients (38 feet). Evaluation included preoperative and postoperative questionnaires, physical examination, and radiographs. RESULTS: Complete clinical data was available for 29 patients (35 feet) and complete radiographic data for 29 patients (34 feet). Average age at surgery was 54 (range 27 to 84) years. Average followup was 42 months (range 29 to 93) months. Average preoperative visual analog pain score was 7.2 and postoperative 2.3 (p < 0.001). Average preoperative AOFAS Hallux MTP-IP Score was 44.8 and postoperative 87.3 (p < 0.001). Average preoperative intermetatarsal (IM) angle was 16 degrees, and the hallux valgus (HV) angle was 34 degrees. Postoperatively, the average IM angle was 6 degrees, the HV angle 11 degrees. There were no cases of nonunion or malunion. Complications included symptomatic hallux varus in two, recurrence of hallux valgus deformity in one, deep venous thrombosis in one, and failure of fixation in one patient. Twenty-four percent of patients (7 of 29) noted the subjective sensation of midfoot stiffness and 34% (10 of 29) noted forefoot stiffness. None of these patients thought that the stiffness was a disability. Ninety percent of patients (26 of 29) were satisfied with their foot function, and 86% (25 of 29) were satisfied with the cosmetic appearance of their foot. CONCLUSIONS: The modified Lapidus procedure results in a satisfactory clinical outcome in most patients. With meticulous operative technique, rigid internal fixation, and strict postoperative weightbearing restrictions, successful union can be achieved and complications can be minimized. Care should be taken to avoid hallux varus, and patients need to be counseled regarding a potentially long convalescent period and possible postoperative stiffness.

Duplication of the hallux.

Sixteen patients with duplication of the hallux were reviewed. Follow-up averaged 21 years. Duplication may be classified into three groups: simple hallucal duplication, a transitional type with a short thick first metatarsal, and complete first ray duplication. Routine removal of the most medial hallux or ray is to be avoided. Careful preoperative assessment is necessary to compare hallucal function, cosmesis, and metatarsal weightbearing. Surgery should also correct the associated congenital hallux varus. Surgical complications include functionless hallucis from inappropriate selection and medial soft tissue contractures with either recurrence of the hallux varus or the gradual development of a hallux varus interphalangeus.

[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.

Metatarsal epiphyseal bracket: treatment by central physiolysis.

Longitudinal epiphyseal bracket (LEB) is a rare ossification anomaly in which an epiphysis brackets the diaphysis of a phalanx, metacarpal, or metatarsal. This abnormal epiphysis tethers longitudinal growth, resulting in a shortened and oval-shaped bone. Four patients with five LEBs were treated by central physiolysis and followed for a mean of 6 years. The patients had significant hallux varus deformity. Three patients had duplicated great toes, and two had tibia hemimelia significant enough to require epiphysiodesis as they neared adolescence. Resection of the LEB allowed the proximal and distal epiphysis to resume untethered growth. Silastic or methyl methacrylate was placed over the resected physis to prevent bony rebridging. The associated hallux varus deformity was corrected by capsulorrhaphy and K-wire fixation. In all patients, the metatarsal resumed longitudinal growth and correction of the hallux varus was maintained.

Bunion correction using proximal chevron osteotomy: a single-incision technique.

Proximal chevron first metatarsal osteotomy with lateral capsulotomy, adductor tenotomy, and binding of the first and second metatarsals was reviewed in 88 consecutive cases. Seventy-two cases in 55 patients are reported, with an average clinical follow-up of 41 months. The hallux valgus angle improved an average of 15 degrees , from 32.0 degrees preoperatively to an average of 17.0 degrees postoperatively. The intermetatarsal I-II angle improved an average of 5.5 degrees, from 15.3 degrees preoperatively to 9.0 degrees postoperatively. The lateral plantar first metatarsal angle did not change. First metatarsal length was decreased by 2.0 mm. Union occurred at an average of 2 months. Sesamoid position improved 49%, from a preoperative average subluxation of 80% to a postoperative average subluxation of 29%. Subjective foot score profiles improved from a preoperative average of 70.1/100 to a postoperative average of 94.4/100 with respect to pain, deformity, motion, disability, and cosmesis. There were 10 patients with complications, including three patients with delayed unions, two with second metatarsal stress fractures, one with hallux varus, two with hallux limitus, one with progressive arthritis, one with cellulitis, and one with hallux elevatus. Eighty-four percent of the patients stated that they would undergo the procedure again without reservation, 9% would proceed with reservation, and 7% would not proceed with surgery again if offered. This technique provides reliable successful long-term results for the treatment of moderate and severe symptomatic bunion, hallux valgus, and metatarsus primus varus.

Hallux valgus repair. DuVries modified McBride procedure.

The DuVries modification of the McBride procedure was investigated in 72 feet in 47 patients with hallux valgus deformity. Overall, the patient satisfaction rate was 92%. The hallux valgus averaged 32 degrees preoperatively, and 16 degrees postoperatively. The intermetatarsal angle averaged 14 degrees preoperatively and 9 degrees postoperatively. Anatomic realignment of the remaining tibial sesamoid was achieved in 28% of the feet. As a result of realignment of the first metatarsophalangeal joint, the intractable plantar keratosis beneath the second metatarsal head was resolved in 19 of 20 feet. Six patients developed a hallux varus deformity that averaged 7.5 degrees. All cases of hallux varus had medial displacement of the tibial sesamoid. The number of patients who could withstand unrestricted shoe wear increased from ten patients preoperatively to 30 patients postoperatively. The patient activity level increased in two thirds of the cases. The distal soft-tissue procedure produces the most predictable correction in patients with a hallux valgus deformity measuring less than 30 degrees. In more severe deformities, a proximal metatarsal osteotomy should be added to the procedure.

Retrospective analysis of the Mau osteotomy and effect of a fibular sesamoidectomy.

The purpose of this study was to evaluate retrospectively outcomes of the Mau osteotomy for hallux abducto valgus deformity. Twenty-two patients were evaluated by the senior author on an average of 14 months (range, 3-34 months) following their surgery. Preoperative and postoperative intermetatarsal (IM) and hallux abductus (HA) angles were evaluated as well as range of motion of the first metatarsophalangeal joint and patient satisfaction. The mean preoperative IM and HA angles were 16.1 degrees and 35.8 degrees. The mean reduction in IM and HA angles was 10.5 degrees and 23.5 degrees, respectively. Joint range of motion was 58 degrees of dorsiflexion (range, 42 degrees-80 degrees) and 11 degrees of plantarflexion (range, 0 degree-20 degrees). There were no cases of delayed healing or avascular necrosis. There were two patients (9%) with radiographic values consistent with hallux varus; however, neither patient had a clinical appearance of hallux varus and neither patient was displeased with the outcome. Ninety-one percent of patients returned to a soft shoe or sneakers in an average of 5.1 weeks following surgery. Eighty-two percent of patients had no pain at the time of their evaluation, and 96% of patients stated they were satisfied or very satisfied with the surgery. Comparing the subgroup of patients who underwent a Mau-Reverdin procedure with another subgroup undergoing a Mau-Reverdin fibular sesamoidectomy, there was a 3.7 degrees greater reduction of IM angle and 6.7 degrees greater reduction in HA angle in the subgroup with the fibular sesamoidectomy.

Correction of moderate to severe hallux valgus deformity by a modified chevron shaft osteotomy.

BACKGROUND: Hallux valgus is one of the most common foot deformities in women. Despite the large number of techniques described for hallux valgus correction, there has been much controversy regarding the best procedure to use, especially for severe deformities. Proximal osteotomies have long been done for severe deformities; however, diaphyseal osteotomies have gained popularity because of the greater degree of correction and stability obtained. METHODS: This study retrospectively assessed the radiographic and clinical outcomes in 50 feet (34 patients) that had a modified chevron shaft osteotomy for moderate to severe hallux valgus. Additionally, an Akin medial closing wedge osteotomy of the proximal phalanx was done in most patients. Mean followup was 30 months (minimum 13 months). All patients in the study had either moderate or severe deformities. Patients with mild deformities had correction by other techniques. RESULTS: There was a mean AOFAS score improvement of 39.6 (44.5 to 84.1) points. The hallux valgus angle and intermetatarsal angle improved a mean of 22.7 degrees and 10.4 degrees, respectively. Hallux valgus persisted in one foot; however, the patient was not dissatisfied. Two feet developed hallux varus. Revision was necessary in two patients; one needed revision because of loss of fixation and the other because of symptomatic hallux varus. CONCLUSION: Based on radiographic correction and clinical outcomes, this procedure is indicated for the treatment of moderate to severe hallux valgus deformities.

Treatment of preaxial polydactyly of the foot.

Fourteen patients with preaxial polydactyly are classified into four types according to their morphologic configuration: type 1--ray duplication; type 2--completely duplicated phalanges; type 3--incompletely duplicated metatarsals; and type 4--incompletely duplicated phalanges. The surgical treatment and timing thereof appropriate for each group are discussed. Three cases of congenital hallux varus deformity are analyzed, focusing on the pathomechanism of this disorder. Based on our experience, two main factors are noticed in the etiology of congenital hallux varus deformity: inadequacy of the adductor hallucis and tightening of the fibrous band pulling the big toe into the varus.

The first metatarsal bicorrectional head osteotomy (distal "L"/Reverdin-Laird procedure) for correction of hallux abducto valgus: a retrospective study.

A retrospective analysis of the distal "L" osteotomy with bunionectomy (Reverdin-Laird procedure) for correction of hallux abducto valgus was performed. Sixty-nine cases meeting strict eligibility and exclusion criteria underwent evaluation an average of 33.51 months after the procedure. The evaluation included radiographs, physical examination, patient survey, and medical record review. The average decreases in radiographic angles were as follows: Hallux abductus: 19.97 degrees, relative intermetatarsal angle: 7.49 degrees, proximal articular set angle: 13.9 degrees. Twenty-seven cases demonstrated a negative proximal articular set angle. Only five of these cases resulted in clinical hallux varus. There was an average of 4.23 mm. of first metatarsal shortening with this procedure. Average postoperative range of motion of the first metatarsophalangeal joint was 72.05 degrees. The appearance of the forefoot was judged good or excellent in 91.3% of the surgeries. Hallux position was in rectus or mild abductus in 86.9% of cases. Complication rates included hallux varus, metatarsalgia, lesion subsecond metatarsophalangeal joint, pain at the surgical site, long-term stiffness, pin tract infection, and numbness. There were no cases of osteomyelitis or avascular necrosis. Survey results revealed a high level of patient satisfaction with this procedure (94.2%). Patient satisfaction was dependent on elimination of pain and ability to wear the desired shoe gear comfortably, not on hallux position.

Bilateral delta phalanx of the proximal phalanges of the great toes. A report on an affected family.

The condition known as delta phalanx (or longitudinally bracketed epiphysis) is a rare congenital anomaly first described in 1964. The deformity consists of a triangular bone with an epiphysis running along the shortened side of the phalanx in a proximal to distal direction, making longitudinal growth of the digit impossible. Isolated hallux varus congenitus due to a delta phalanx of the proximal phalanges of both great toes is extremely rare: there have been only three such cases reported, two of which were in one family--the only report of a familial occurrence of this deformity. This present report details the occurrence of isolated bilateral hallux varus congenitus in four members of one family, a father and his three eldest children. All three children show bilateral delta phalanx of the proximal phalanges of both great toes. There are associated thumb nail anomalies, but no suggestion of polydactylism.

Lethal hydrops fetalis due to congenital dyserythropoietic anemia in a newborn: association of a new skeletal abnormality.

Congenital dyserythropoietic anemias (CDAs) are a group of hereditary refractory anemias characterized by ineffective erythropoiesis, typical morphological abnormalities of erythroblasts, a low or no reticulocyte response, hyperbilirubinemia, and splenomegaly. A massive hydropic newborn born with a very severe anemia (Hb 4.8 g/dL), diffuse edema, hepatosplenomegaly, ascites, pulmonary edema and respiratory distress, and shortness and hallux varus deformity of the great toe of the right foot was diagnosed to have congenital dyserythropoietic anemia on the basis of the hematological (macrocytosis, anisopoikilocytosis, fragmented red cells and erythroblastosis in the peripheral blood, and erythroid hyperplasia with erythroblastosis and erythroblasts with double nuclei and thin chromatin bridges connecting these nuclei in the bone marrow) and serological (negative acidified serum lysis test and no agglutination with anti-i antibodies) findings. In this article the seventh case of neonatal congenital dyserythropoietic anemia presenting with a very severe (lethal) form of hydrops fetalis and a new (hallux varus) deformity of the great toe of the right foot is presented. Congenital dyserythropoietic anemia should be considered in the differential diagnosis of hydrops fetalis presenting with a very severe anemia and a skeletal abnormality of the great toe.

Polydactyly of the foot: manifestations and treatment.

Polydactyly of the foot is not an uncommon foot problem. However, it is not well understood and not often reported. Its clinical manifestations vary, as do treatment methods and results. During the period of 1979 to 1994, 54 children with polydactyly of 65 feet were treated in our clinic. Bilateral involvement was seen in 11 patients, and six had accompanying polydactyly of the hand. By Blauth and Olason's classification, duplication of the fifth ray (43 feet) was most common, followed by first ray duplication (20 feet) and other ray duplication (2 feet). A rudimentary form was found in one foot. Polysyndactyly was present in 18 feet. Hallux varus was the most common associated problem and was present in seven feet. Surgery for both cosmetic and functional purposes was performed in 38 patients (44 feet). Treatment included excision of the extra toe and reconstruction of the soft tissue around the remaining toe, of which the alignment was restored in cases of deviation. Results were evaluated with Phelps-Grogan's protocol; 39 feet (88%) were classified as having excellent results, two (5%) had good, and three (7%) had poor results. Postoperative complications included residual hallux varus in three feet with polydactyly of the first ray, and unpleasant surgical scars in another two. We conclude that polydactyly of the foot should be treated individually, depending on classification. Special attention should be paid to complex first ray polydactyly.
