Paleopathological study of hallux valgus.

Hallux valgus is the abnormal lateral deviation of the great toe. The principal cause is biomechanical, specifically the habitual use of footwear which constricts the toes. In this study, descriptions of the anatomical changes of hallux valgus from published cadaveric and clinical studies were used to generate criteria for identifying the condition in ancient skeletal remains. The value of systematic scoring of hallux valgus in paleopathology is illustrated using two British skeletal series, one dating from the earlier and one from the later Medieval period. It was found that hallux valgus was restricted to later Medieval burials. This appears consistent with archaeological and historical evidence for a rise in popularity, during the late Medieval period (at least among the richer social classes), of narrow, pointed shoes which would have constricted the toes.

Insertion of the tendon of the tibialis anterior muscle in feet with and without hallux valgus.

The insertion of the tendon of the tibialis anterior muscle may be related to pathologic changes of the foot and, in particular, hallux valgus. Morphologic data should enable evaluation of such a relationship and perhaps offer a basis for improved therapy. One hundred fifty-six embalmed feet, including 27 with hallux valgus, were examined. The tendon of the tibialis anterior muscle was dissected and measurements were made, including the width of the insertion on the first metatarsal and medial cuneiform. Distal-superficial and proximal-deep slips of the tendon twisted around each other. Two specimens presented with an insertion only on the medial cuneiform; in two other cases the insertion was limited to the first metatarsal; in one case the tendon inserted into the navicular and the medial cuneiform; in all other cases, the tendon inserted into the medial cuneiform and first metatarsal. The insertion was mainly located along the plantar margin of the medial side of the foot; some of the proximal-deep fibers also passed onto the plantar surface. Fibers inserting on the first metatarsal bone can outwardly rotate the first ray, which is opposite to the inward rotation of the first ray in hallux valgus. In all feet with hallux valgus these fibers were present. Therefore, it is unlikely that this deformity develops because of a specific type of insertion of the tendon of the tibialis anterior muscle, and any therapeutic approach altering the attachment of the tibialis anterior tendon would cause no biomechanical improvement.

Evaluation of the longitudinal arch of the foot with hallux valgus using a newly developed two-dimensional coordinate system.

The purposes of the present study were to establish a method for the evaluation of the longitudinal arch, using a two-dimensional coordinate system, and to clarify the main point of flattening of the foot in patients with hallux valgus. Measurements on a weight-bearing lateral radiograph of the foot were performed in 186 feet of 110 women with symptomatic hallux valgus and in 93 normal feet of 72 women. A two-dimensional coordinate system was used to perform the measurements. In this coordinate system, the line connecting the lowest point of the first metatarsal head and the lowest point (O) of the calcaneus is fixed as the x-axis, and the line that is perpendicular to the x-axis and intersects the x-axis at point O is fixed as the y-axis. The mean values of the y-coordinates at the points of the medial longitudinal arch of the foot in the patients with hallux valgus were significantly lower than those in the normal subjects (P < 0.001). The values were noticeably lower at points on the navicular. However, no change was observed in the posterior talus body. The new coordinate system indicated that the main points of flattening of the foot in patients with hallux valgus were the plantar flexion of the talus and the sinking of the navicular.

A patient-based questionnaire to assess outcomes of foot surgery: validation in the context of surgery for hallux valgus.

BACKGROUND: A patient-based outcome measure with good measurement properties is urgently needed for use in clinical trials of foot surgery. METHODS: We evaluated an existing foot pain and disability questionnaire (the Manchester Foot Pain and Disability Questionnaire) for its suitability as an outcome measure in the context of hallux valgus corrective surgery. Interviews with patients led to initial changes, resulting in 20 candidate questionnaire items with five response categories each. These were tested in a prospective study of 100 patients (representing 138 foot operations) undergoing hallux valgus corrective surgery. Analysis of underlying factor structure, dimensionality, internal reliability, construct validity and responsiveness of the questionnaire items in relation to (i) SF-36 general health survey and (ii) American Orthopaedic Foot & Ankle Society (AOFAS) hallux clinical scale resulted in a final 16 item questionnaire (the 'Manchester-Oxford Foot Questionnaire' (MOXFQ)), consisting of three domains/scales: 'Walking/standing' (seven items), 'Pain' (five items) and 'Social interaction' (four items) each having good measurement properties. All three domains were unidimensional. CONCLUSIONS: The new 16-item MOXFQ has good measurement properties in the context of outcomes assessment of surgery for hallux valgus. Future studies should assess the MOXFQ in the context of surgery for other foot and ankle conditions.

Management of soft tissue deficiency of the hallux: salvage in trauma, diabetes, and following surgical complications.

Loss of the hallux can lead to significant gait problems and cause difficult biomechanical problems with weight bearing. Amputation of the first ray should be avoided when possible. Soft tissue defect of the hallux can be particularly difficult to manage because of the absence of local muscle tissue for coverage. In younger patients, soft tissue loss usually is related to trauma; an understanding of the techniques that are available for coverage are important to maintain length and function of the first ray. Diabetic neuropathy and resultant ulceration of the hallux or metatarsophalangeal joint is another common cause of soft tissue deficiency that may lead to deep infection and potentially result in amputation. Certain systemic problems, such as inflammatory diseases or gout, can cause significant degeneration of the local tissues which also can be problematic. Wound dehiscence or loss of skin flaps that are created during surgery represent further difficulties that may be encountered. This article reviews the common causes of amputation of the hallux and the principles that are necessary for salvage of the digit.

Hallux IPJ fusion.

Surgical arthrodesis of the hallux interphalangeal joint can be used as an isolated procedure to address painful or deformed joints or in conjunction with other procedures to create a better functioning first ray. This type of arthrodesis may be necessary in neuropathic patients to prevent ulcerations or amputations. Several etiologies exist that result in a deformity about the hallux IPJ, some can be pain-free, others may be extremely debilitating to a patient. Many different surgical approaches have been described and used when performing a hallux IPJ arthrodesis. Developing your own technique enables you to understand what works for you and your patients and allows you to determine the most effective way to achieve arthrodesis. The goal is to prevent painful nonunions and address the underlying deformity. It is also important to understand that a successful arthrodesis in a patient who has a neurological disorder is the only way to prevent recurring deformities secondary to the underlying disease process. The ability to properly work-up and surgically address deformities of the hallux interphalangeal joint is necessary for those who perform lower extremity surgery.

First metatarsocuneiform arthrodesis and Reverdin-Laird osteotomy for treatment of hallux valgus: an intermediate-term retrospective outcomes study.

The authors present a retrospective study of 14 patients (20 feet) treated with first metatarsocuneiform arthrodesis and Reverdin-Laird osteotomy and distal soft tissue alignment for hallux valgus associated with hypermobility of the first ray and an increased proximal articular set angle. The purpose of this study was 3-fold: (1) to determine clinical outcome of this procedure combination, (2) to evaluate the effect of this procedure on the radiographic parameters of hallux valgus, and (3) to determine the degree of first ray shortening. At a mean 50.1 months postoperatively, patients were evaluated according to the American Orthopedic Foot and Ankle Society's Hallux-First Metatarsophalangeal-Interphalangeal Clinical Rating Scale. Preoperative and follow-up radiographs were compared for changes in the following measurements: 1-2 intermetatarsal angle (IMA), hallux abduction angle (HAA), proximal articular-set angle (PASA), and metatarsal protrusion distance (MPD). Statistical analysis using the Student t test showed a significant increase in total scores from a mean 43.6 to 92.6 of 100. A significant decrease was found in the IMA from a mean 16.9 degrees to 7.1 degrees, in the HAA from a mean 37.1 degrees to 5.2 degrees, in the PASA from a mean 20.3 degrees to 3.4 degrees (P <.001), and a significant change in the was found in the MPD of 7.7 mm (P <.001). Given the high rating scale scores, first ray shortening did not appear to hamper our patients' clinical outcome.

The role of cheilectomy in the treatment of hallux rigidus.

The aim of this study was to evaluate and compare the outcome of cheilectomy for patients with grades 1, 2, and 3 hallux rigidus according to Regnauld's classification. We evaluated 39 patients at a mean of 3.8 years after surgery for pre- versus postoperative changes in pain, activity level, difficulties with footwear, tiptoe walking, and metatarsophalangeal joint range of motion. We used Wilcoxon paired rank tests to compare outcomes for each grade of hallux rigidus. There was significant improvement (p < 0.05) in pain, activity level, tiptoe walking, and range of motion for all three grades of hallux rigidus. Footwear selection was significantly improved in Grades 1 and 2 patients but not in patients with Grade 3 hallux rigidus.

Modified lapidus arthrodesis for adolescent hallux abducto valgus.

The Lapidus arthrodesis was originally described for the surgical correction of hallux valgus associated with metatasus primus adductus. It was popularized on the adult patient with moderate to severe hallux valgus deformity. However, the authors present a retrospective review of 23 adolescents between the ages of 13 and 20 who underwent the procedures. Characteristics of adolescent hallux valgus include a smaller dorsal medial eminence, less valgus rotation of the hallux, and certain mechanical influences. These influences may include a generalized increase in motion at the first metatarsocuneiform joint. The modified Lapidus arthrodesis eliminates motion at the first metatarsocuneiform joint and therefore directly addresses an etiology of the deformity. Both preoperative and postoperative radiographs were evaluated for reduction in the 1-2 intermetatarsal angle. Patients were evaluated through either chart review or telephone interview for present activity level, comfortable footgear, and overall satisfaction of the procedure. Twenty-seven out of 30 feet (90%) had either a good or excellent result with only three complications and two recurrences over a mean follow-up of 61 months.

BIOPRO resurfacing endoprosthesis versus periarticular osteotomy for hallux rigidus: short-term follow-up and analysis.

Forty-four patients (47 feet) were enrolled in a prospective hallux rigidus study. A subjective evaluation, physical examination, and radiographic analysis were performed preoperatively and at a 1-year follow-up. Twenty patients (20 feet) underwent a periarticular osteotomy, with 16 patients (16 feet) returning. Seven patients (9 feet) underwent a BIOPRO resurfacing endoprosthesis, with all patients returning. The subjective evaluation was based on a modified American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal 100-Point scale. The physical examination included first metatarsophalangeal joint range of motion. Radiographic analysis included the metatarsal protrusion distance, transverse plane angulation of the second digit, lateral talo-first metatarsal angle, sagittal plane relationship of the first and second metatarsals, and hallux equinus angle. Statistically significant differences between preoperative and postoperative values were found for the periarticular osteotomy group for the metatarsal protrusion distance (P =.000), transverse plane angulation of the second digit (P =.000), and lateral talo-first metatarsal angle (P =.015). No other statistically significant differences between the pre-operative and post-operative values for either procedure group were found to exist. For this specific patient population the short-term results of surgical intervention for hallux rigidus, whether through a periarticular osteotomy or resurfacing endoprosthesis, provided subjective patient improvement and satisfaction, as well as, minimal increase in first metatarsophalangeal joint range of motion.

The modified Hohmann osteotomy: an alternative joint salvage procedure for hallux rigidus.

The purpose of this study was to evaluate the effectiveness of the modified Hohmann osteotomy for treatment of hallux rigidus. By allowing plantarflexion of the first metatarsal head, this osteotomy was theorized to protect gliding motion and to decompress the joint. Twenty-two patients (25 procedures) were assessed preoperatively and postoperatively for the first metatarsal plantarflexory osteotomy. The average postoperative follow-up was 12 months, with a range of 6 to 60 months. Postoperative subjective patient questionnaires showed the following: 96% reported excellent subjective ratings with no fair or poor ratings, 80% reported a return to normal activity within 1 to 2 months, no patients reported any significant limitations in their activity or reoccurrence of pain, and no patients reported any need for a revision surgery other than hardware removal. A goniometer was used to measure preoperative and postoperative dorsiflexion and plantarflexion at the first metatarsophalangeal joint. The patient first metatarsophalangeal joint dorsiflexion increased from a mean 17.76 degrees preoperatively to a mean 58.92 degrees postoperatively. The ability to hold a piece of paper under the hallux for purchase power was also evaluated. Only 2 of 25 procedures lacked the purchase power to effectively hold a piece of paper with the hallux. Thus, the modified Hohmann osteotomy provides an excellent alternative joint-salvaging procedure for moderate to severe hallux rigidus.

A plantar-flexor-shortening osteotomy for hallux rigidus: a retrospective analysis.

This retrospective study reported the clinical and radiographic findings of a plantar-flexor-shortening first metatarsal osteotomy for treatment of hallux rigidus. Twenty-six patients (33 feet) were evaluated with a mean 34.4 months follow-up (range, 18-65 months). Assessment consisted of clinical measurements of total range of first metatarsophalangeal joint motion and radiographic measurements of first metatarsophalangeal joint space, including plantarflexion and shortening of the first metatarsal. Patients were evaluated postoperatively using the American Orthopedic Foot and Ankle Society's Hallux Metatarsophalangeal-Interphalangeal Scoring System. The mean preoperative first metatarsophalangeal joint total range of motion was 33.5 degrees (5 degrees -60 degrees ), and postoperatively increased to 72.1 degrees (50-100 degrees ), a mean increase of 38.6 degrees at follow-up (range, 25 degrees -60 degrees ) (P < .001). This range of motion was observed despite a lack of significant improvement in radiographic joint space measurements, (preoperative mean 1.26; postoperative mean 1.82). Postoperative radiographs also demonstrated 1-4 mm of plantarflexion of the first metatarsal head, and a mean 6.1 mm shortening of the first metatarsal. At last follow-up, 85% (22/26) of patients rated their result as very good to excellent, 8% (2/26) reported a good result, 4% (1/26) a fair result, and 4% (1/26) a poor result. The mean postoperative rating scale score was 78.1/100. No patient required revisional surgery for hallux rigidus. Four patients had postoperative lesser metatarsalgia, 3 of which were self-limiting, and one that resolved following surgery. The results of this study show the plantar-flexor-shortening first metatarsal to be an effective surgical treatment for hallux rigidus with reproducible deformity correction and patient satisfaction.

Endometrial carcinoma metastasis to the distal phalanx of the hallux: a case report.

Endometrial carcinoma is the most common invasive cancer of the female genital tract and accounts for 7% of all invasive cancer in women. Bony metastasis is uncommon with endometrial carcinoma and distal metastasis is very rare. The purpose of this paper is to present a case of an 86 year-old female with endometrial carcinoma metastasis to the distal phalanx of the hallux. The patient had a known history of endometrial carcinoma with metastases (FIGO IIIC), and had been diagnosed with pulmonary and bony metastases 2 months prior to presentation. Her initial foot complaint was of a painful, infected ingrown toenail. The infection continued to progress following avulsion of the nail, and the patient was then diagnosed with osteomyelitis. Given her past history, the possibility of metastasis to the hallux was also considered. A hallux amputation was performed, and the pathology report revealed the diagnosis of endometrial carcinoma metastasis to the distal phalanx of the hallux. While the amputation site healed uneventfully, the patient refused further treatment measures for her carcinoma and eventually succumbed to the disease.

A retrospective analysis of surgical treatment in patients with symptomatic hallux rigidus: long-term follow-up.

The objective of this retrospective study was to analyze the long-term clinical outcomes and patient satisfaction of operative care in patients with symptomatic hallux rigidus. Seventy-seven patients (94 feet) underwent cheilectomy, Keller resection arthroplasty, or arthrodesis between 1990 and 2000. All were invited to return for follow-up evaluation after a minimum of 2 years (mean, 7 years). The average patient age was 53 years (range, 22-77 years). Outcomes were assessed by questioning and examining the patients and by evaluating radiographs according to the Regnauld's classification system. Overall patient satisfaction was good; average visual analogue and American Orthopedic Foot and Ankle Society (AOFAS) Hallux Metatarsophalangeal-Interphalangeal scores were 1.8 and 81, respectively. Eighty-seven percent stated they would undergo the same procedure again. After cheilectomy, the average visual analogue score was 1.4 for grade I and 2.3 for grade II, and rating scale scores were 87 and 82, respectively. There were comparable results for the Keller resection arthroplasty where visual analogue scores were 0.4 and 1.6, respectively, while AOFAS scores were 94 and 83, respectively. Average visual analogue scores and AOFAS scores in grade III patients after a Keller procedure and an arthrodesis were 2.3; 87 and 2.0; and 73, respectively. In the arthrodesis group, 4 patients required revision because of complications. Cheilectomy is a good choice for patients with grade I and II hallux rigidus because it is a safe and simple joint-preserving procedure. For end-stage hallux rigidus without preexistent metatarsalgia, the Keller procedure was favored over arthrodesis of the first metatarsophalangeal joint.

[Resection-interposition arthroplasty in symptomatic hallux valgus: a revision of indication and technique].

AIM: Popularity of resection-interposition-arthroplasty is decreasing due to more specific procedures in hallux valgus surgery. Therefore we analysed the influence of preoperative parameters and technical details to reevaluate this classic procedure. METHOD: In a retrospective, clinical and radiological long-term study (mean 9.6 years) 62 operated feet were examined and the assessed parameters were analysed, with focussing on the negative results. For comparison negative and positive outcome was defined by a hallux-metatarsal-interphalangeal scale (HMIS) and a subjective rating score (SRS). RESULTS: Negative outcome, 34 % according to HMIS and 24 % according to SRS, was characterised in both scoring systems by pain (visual analogue scale), functional deficit (walking distance) and negative cosmetic result (hallux-valgus-angle) (p < 0.01 each). As negative predictive factors we observed an early degenerative arthritis (p < 0.05, HMIS) and a positive metatarsal index (p < 0.05, SRS). Unsatisfactory results were related to an increased resection level of the first phalanx when compared with good results (p < 0.01 in HMIS, p < 0.05 in SRS). CONCLUSION: Resection-interposition arthroplasty in symptomatic hallux valgus seems an inadequate procedure in cases with early arthritis or a positive metatarsal index. However, in accordance with these criteria good results are probable, if resection of the first phalanx does not exceed one third of length.

[Hallux valgus: a therapy concept and its outcome from 1993 to 1996].

INTRODUCTION: Aim of this study is to present the treatment concept and the results of hallux valgus surgery of our department. PATIENTS AND METHODS: The criteria for decision making are 1st intermetatarsal angle, congruency of the first metatarsophalangeal joint and sesamoid position. According to our concept we performed between 1993 and 1996 42 Chevron osteotomies for mild, 138 Chevron with lateral soft tissue release (Chevron + LSR) for moderate and 93 basal crescentic (Mann) osteotomies with lateral soft tissue release for severe hallux valgus deformities. RESULTS: 31 Chevron, 118 Chevron with lateral soft tissue release and 80 basal crescentic osteotomies (Mann) were seen at an average follow up of 19 months (12-29) after a Chevron, respectively. 16 months (12-43) after Chevron with lateral soft tissue release and 18 months (12-32) after a basal crescentic osteotomy. 83% of all patients classified the results of the surgery as "very satisfactory" and "satisfactory". The average hallux valgus angle was corrected from preoperatively. 25.3 degrees (Chevron), 29.9 degrees (Chevron + LSR) and 41.8 degrees (Mann) to 16.5 degrees (Chevron), 12.1 degrees (Chevron + LSR) and 14.1 degrees (Mann) at final follow up, the average first intermetatarsal angle was corrected from preoperatively 12.1 degrees (Chevron), 14.0 degrees (Chevron + LSR) and 17.4 degrees (Mann) to 7.9 degrees (Chevron), 5.8 degrees (Chevron + LSR) and 7.8 degrees (Mann) at final follow up. CONCLUSION: Our analysis of the three osteotomies revealed that with this differentiated concept we were able to achieve excellent and good results in more than 80% of our patients. Only with a treatment plan that includes different procedures to address the various stages of hallux valgus can one achieve the optimum result for the patient.

Hallux valgus in young patients: comparison of soft-tissue realignment and metatarsal osteotomy.

Two procedures of hallux valgus correction in young patients were compared by long-term results: soft-tissue realignment (McBride) and Mitchell osteotomy. From 1970 to 1990, 33 hallux valgus deformities of 17 patients were corrected with one of these procedures at the Orthopaedic Department of the University of Mainz. Patients' age at operation ranged from 9 to 20 years and average follow-up was 16 years later. Reevaluation consisted of subjective criteria, such as pain, shoe-fitting, functional disability and cosmetics and objective parameters (hallux-valgus and intermetatarsal angle, osteoarthrotic changes and range of motion of the metatarsophalangeal joint). They were assessed by report, interview, radiograph and physical examination and determined the overall outcome. McBride procedure showed 59% good, 12% satisfying and 29% dissatisfying long-term results, whereas outcome after Mitchell osteotomy was graded as good in 69%, satisfying in 12% and dissatisfying in 19% of the cases. Critical analysis emerged, that each procedure has its own bounds of indication. Successful hallux valgus correction can be achieved by an individual approach consisting of careful study of the indications, well-performed surgery and appropriate postoperative care.

Distal soft tissue procedure and proximal metatarsal osteotomy in hallux valgus.

The results of a distal soft tissue procedure and a proximal metatarsal osteotomy in patients with symptomatic hallux valgus deformity were reviewed. The series consisted of 33 patients (47 feet; mean age of patients, 44 years). The average followup period was 48 months. At followup, 41 feet (29 patients, 85%) were free from pain at the first metatarsophalangeal joint. In six feet (four patients), the pain was improved but persisted. The mean hallux valgus angle was 38 degrees before surgery and 13.8 degrees after surgery. The mean intermetatarsal angle was 17.7 degrees before surgery and 7 degrees after surgery. The postoperative hallux valgus angle and intermetatarsal angle in patients who had pain at the first metatarsophalangeal joint after surgery were greater than those in patients without pain after surgery. This procedure corrects the hallux valgus deformity and relieves the symptoms, but careful attention should be paid to the surgical technique to obtain consistent and satisfactory results.
