Hallux valgus in men. Part II: First ray mobility after bunionectomy and factors associated with hallux valgus deformity.

PURPOSE: To determine the 1st ray mobility following a distal soft-tissue procedure with proximal osteotomy (DSTP-PMO) and any associated factors. METHODS: A retrospective study of 30 men (35 feet) was performed. First ray mobility, ankle dorsiflexion, pes planus, and metatarsus adductus were evaluated at the final follow-up. All internal fixation was routinely removed at six to eight weeks postoperatively. Standard radiographs were evaluated and angular measurements were calculated on all feet. RESULTS: The mean follow-up was 78 months. No cases of degenerative arthritis of the 1st MTC joint were noted on follow-up radiographs. DSTP-PMO resulted in a mean postoperative 1st ray mobility of 4.9 mm (range, 2.5 to 8). In those feet evaluated following bunion correction, there was no correlation with pes planus, limited ankle dorsiflexion or metatarsus adductus. The preoperative hallux valgus angle and 1-2 intermetatarsal angle correlated with toe pronation and a positive family history. Twenty-two patients had an AOFAS score of 90-100, seven of 80-89 and one less than 69. CONCLUSION: Hallux valgus in this group of male patients was not associated with limited ankle dorsiflexion or pes planus. Men with toe pronation and a positive family history had a greater hallux valgus deformity than those without after a distal soft tissue repair with proximal first metatarsal osteotomy. There was no evidence of first ray hypermobility after a DSTP-PMO.

Operative repair of fourth and fifth toe corns.

METHODS: We report a retrospective review of 57 consecutive patients (72 feet) over a period of 20 years who had been treated operatively for either a lateral fifth toe corn or an interdigital corn of the fourth interdigital space more than two years previously. Of these, 51 patients (62 feet) returned for a follow-up evaluation at a minimum of two years (average of over seven years) which included a review of the interval history since the surgery, a physical examination, a radiographic evaluation, and assessment of the patient's satisfaction with the alignment and results of surgery. Treatment of 31 lateral fifth toe corns involved either a lateral condylectomy and flexor tenotomy or a complete condylectomy. Treatment of 31 interdigital corns comprised either a single condylectomy, double condylectomy of adjacent corns, or a complete condylectomy (hammertoe repair) of a symptomatic corn. Treatment in each case was dependent upon the severity of the deformity. RESULTS: There was found to be no significant difference in comparison of the two major groups (interdigital corns and lateral fifth toe corns) with the measurement of the relative length of the fourth and fifth metatarsals, toe malalignment, angulation of the fourth and fifth toes (MTP-4, MTP-5 angles), and the phalangeal-5 angle. Pain was relieved in 58 of 62 feet (93%) and subjective acceptable alignment was achieved in 54 of 62 feet (87%). At final follow-up 53 feet were rated by patients as excellent, seven as good, one as fair, and one as poor. Complications included numbness of the involved digit (six feet). There were two superficial infections. There were two cases of joint instability due to excessive bone resection. Joint stiffness was commonly observed (34/62 feet, 55%), but was not associated with diminished satisfaction at final follow-up. Mild asymptomatic recurrence of a callosity was noted in 10 feet and moderate or severe recurrence was noted in two feet. Dissatisfaction was associated with moderate or severe recurrence. CONCLUSION: In this retrospective study at an average of more than seven years, we achieved a high level of patient satisfaction treating both lateral fifth toe corns and interdigital corns with a partial and/or complete condylectomy, the choice depending upon the magnitude of the deformity and the callus, and the fixed nature of the lesser toe deformity.

Lesser toe abnormalities.

Lesser toe abnormalities, which can result in significant pain and discomfort, are caused by several intrinsic or extrinsic factors including inflammatory arthritis, trauma, congenital abnormalities, neuromuscular disorders, or poorly fitting shoe wear. Identification of the etiology of the deformity is necessary to determine whether conservative or surgical treatment is warranted and to possibly halt progression of the deformity.

Concurrent interdigital neuroma and MTP joint instability: long-term results of treatment.

INTRODUCTION: An interdigital neuroma is a common source of forefoot pain, and while second metatarsophalangeal joint instability is a less common entity, it can be a concomitant source of pain. The purpose of this study was to evaluate the long-term clinical course and surgical outcomes of the treatment of these concomitant problems. METHODS: 121 consecutive patients (131 feet and 136 neuromas) were evaluated and treated for a symptomatic interdigital neuroma from 1981 to 1997. Of these, 24 patients (20%) had a concurrent interdigital neuroma (IDN) and second metatarsophalangeal (MTP) capsular instability that underwent surgical treatment. At the final follow-up examination, 20 patients (21 feet) were evaluated by an independent orthopaedic surgeon with a standardized clinical and radiographic examination, patient self-assessment and outcome measures. RESULTS: Overall, there were 18 females and two males (21 feet) treated with an average age of 54 years at the time of surgery that returned for examination and follow-up at an average of 80 months (48 to 108 months) following surgery. Seventeen patients (85%) rated their result as good or excellent and three as fair. Six patients had mild continued symptoms referable to the second toe and none to the neuroma. Simultaneous neuroma excision and second MTP stabilization was performed in 15 cases and in six cases a staged repair was performed. The mean visual analog pain score was 1.4 (0=no pain, 10=severe pain) and mean MHAQ score was 1.13 (1-1.625) with activity modification stemming from hip, back and knee complaints. CONCLUSION: With careful patient selection and preoperative assessment, resection of an interdigital neuroma and stabilization of second metatarsophalangeal joint instability resulted in a high percentage of successful results at greater than four years following the procedure. Objective results were comparable to previous reports on the surgical treatment of isolated interdigital neuroma and crossover second toe reconstruction. Subjective patient satisfaction was high but both subjective and objective results were lower in patients with persistent symptoms of MTP instability.

Augmented lateral ankle reconstruction using a free gracilis graft.

This article describes a surgical technique for reconstruction of the unstable ankle that uses a modification of the Elmslie procedure for anatomic augmentation of the anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL). Our technique is an anatomic reconstruction that uses a free graft of the gracilis tendon toreconstruct the CFL and A TFL.
