The authors present a brief history of the development of the Ilizarov external fixator, and the classic uses associated with it. A preliminary study of 3 patients using 56 frames is presented. The Ilizarov external fixator is successfully used in these cases in place of traditional fixation.
A case presentation of an adolescent with tarsal navicular avascular necrosis is presented. External fixation with tarsal navicular diastasis is a simple, straightforward management option to allow osseous regrowth and bone healing. In this case, the external fixator was well tolerated and the patient demonstrated a quick return to function without pain or discomfort. The external fixation technique with tarsal navicular diastasis is an uncommon but effective means of reversing the tarsal navicular avascular process and avoiding an open technique such as arthrodesis.
The Treatment of Complex Motorcycle Spoke Injuries in Children
A Report of Four Cases and Literature Review
Motorcycle spoke injuries involving the soft tissue, Achilles tendon, and calcaneal defects are rare in children. Currently, calcaneal defects are very challenging to treat. Multiple methods have been used in clinical practice; however, an effective treatment has yet to be established, especially when Achilles tendon and soft-tissue defects are also present. It is important to address this condition, because the calcaneus plays a key role in standing and gait. Unsatisfactory treatment of calcaneal defects may significantly decrease patients' quality of life (eg, by limiting mobility). In this article, we report the effective treatment of calcaneal defects in four children using distraction osteogenesis with an external fixator framework designed by the authors. From May 2014 to May 2015, four children (age range, 6–11 years) with defects of the Achilles tendon, soft tissue, and calcaneus resulting from a motorcycle accident were treated at our hospital. The Achilles tendon and soft-tissue defects were treated with second-stage reconstruction. In the third-stage surgery, osteotomy of the residual calcaneus was performed. A customized external fixator was used to lengthen the calcaneus at a rate of 1.5 mm/day in the posterior direction and reposition it by 40° in the inferior direction. In all four children, the calcaneus was lengthened by 5 cm. Distraction osteogenesis through external fixation is effective for restoring the length, width, and height of the calcaneus in children.
Management of Grade III Open Dislocated Ankle Fractures
Combined Internal Fixation with Bioabsorbable Screws/Rods and External Fixation
Background:
Isolated dislocation of the ankle with grade III open fracture has been scarcely reported. These ankle injuries usually involved mortise fractures, complete dislocation of the tibial astragaloid joint, capsuloligamentous structure disruption, and severe soft-tissue damage. There is no well-recognized regimen that would result in desirable outcomes.
Methods:
Sixteen patients with grade III open dislocated ankle fractures were treated immediately with bioabsorbable implants and an external fixator between January 2003 and June 2007. According to the classification system of Gustilo and Anderson, five patients were grade IIIA, seven were grade IIIB, and four were grade IIIC. Surgical interventions included combined internal fixation with bioabsorbable screws/rods and external fixation.
Results:
Patients underwent clinical and radiologic examination at an average of 18.1 months after surgery. Outcomes were excellent in seven patients (three IIIA, three IIIB, and one IIIC), good in four (one IIIA, two IIIB, and one IIIC), fair in three (one IIIA, one IIIB, and one IIIC), and poor in two (one IIIB, and one IIIC). In the two patients with poor outcomes, bone defect and cartilage exfoliating in the distal tibia were found during surgery. Painful osteoarthritis in the ankle was discovered 2 years after surgery. Another case had pin tract infections in the external fixator 3 months after surgery. There was no case of late deep infection.
Conclusions:
It may be a reasonable and desirable option that bioabsorbable implants combined with an external fixator be applied for treatment of severe open dislocated ankle fractures. (J Am Podiatr Med Assoc 101(4): 307–315, 2011)
Presented here is a preliminary report of 102 patients who underwent first metatarsocuneiform joint arthrodeses performed with external fixation for the correction of hallux valgus. The advantages of using external fixation are the ability to initiate early weightbearing, predictable fusion, and removal of all of the hardware postoperatively. In the 102 patients reported here, the average time to initiation of unassisted full weightbearing was 13.1 days. The average time to fusion was 5.3 weeks, with removal of the external fixator at an average of 5.5 weeks postoperatively. There was no incidence of delayed union or nonunion. There was one case of pin-tract irritation, which resolved with appropriate pin care and a short course of oral antibiotics. External fixation is an effective alternative to traditional internal fixation techniques in metatarsocuneiform joint arthrodesis. (J Am Podiatr Med Assoc 95(4): 405–409, 2005)
Abstract
Background: Many surgical techniques have been reported for the treatment of ingrown toenails. Occurrences of infection after matricectomy procedures could cause clinicians to prefer using external braces to treat ingrown toenails. This study compares patients with ingrown toenails who underwent the nail fixation technique and the Winograd technique.
Methods: Patients who underwent ingrown toenail surgery were retrospectively reviewed. The patients’ demographic characteristics (age, gender, body mass index [BMI] morphology according to Heifetz classification, surgical technique, visual analog scale (VAS) values, time to return to daily activities (days), complications, and satisfaction levels were all recorded.
Results: Seventy patients were included in the study. Of the patients, 33 underwent nail fixation and 37 underwent the Winograd technique. No significant statistical differences were found in terms of patients’ age, gender, BMI, preoperative clinical features, long-term satisfaction, and ingrown toenail recurrence rates between the two groups, but time to return to daily activities and VAS values were statistically significantly lower in patients treated using nail fixation compared with the Winograd technique.
Conclusion: Nail fixation can be an effective surgical treatment option for an ingrown toenail.
One of the challenges after central ray resection is a large soft-tissue defect. Many authors have reported the use of external fixators as a means of narrowing the forefoot. Ours is the first article to report an interesting case using widely available and inexpensive tools such as Kirschner and cerclage wires as an external fixation means of narrowing the forefoot after a complete second-ray resection and extensive soft-tissue debridement for a severe diabetic foot ulcer. This simple yet inexpensive technique is easy to perform for any foot and ankle surgeon at any hospital or surgical center.
Osteoid Osteoma
An Uncommon Cause of Foot Pain
An osteoid osteoma located in the forefoot can be difficult to diagnose, and the diagnosis is frequently delayed. We present a clinical case of a patient with pain, erythema, and swelling of the left forefoot with no history of trauma. Although rarely seen in the metatarsal, osteoid osteoma should be included in the differential diagnosis of foot pain. Findings from radiographs, magnetic resonance images, and a detailed clinical history led to the diagnosis of osteoid osteoma of the left second metatarsal. The lesion was surgically excised using curettage. This process significantly weakened the lateral cortex of the metatarsal shaft. To correct this surgically induced stress riser, an external fixator was applied to provide stability, allow for callus distraction, and allow the patient to walk as early as possible. We review osteoid osteoma, including the classic clinical presentation and treatment associated with this benign bone tumor. (J Am Podiatr Med Assoc 97(5): 405–409, 2007)
This article describes a joint-preserving and joint-restoring procedure for the management of hallux limitus and hallux rigidus. The procedure uses a minirail external fixator to obtain distraction with or without arthrotomy of the first metatarsophalangeal joint. This procedure aims to restore joint function through elimination of the pathologic forces involved in hallux limitus and hallux rigidus. Both intrinsic and extrinsic muscular imbalances are reduced. Follow-up of 133 patients treated in this manner since 1997 demonstrates excellent long-term results. (J Am Podiatr Med Assoc 95(2): 121–129, 2005)
A Rare Combination of Brachymetatarsia and Congenital Hallux Varus:
Case Report and Review of the Literature
Hallux varus is defined as a medial deviation of the phalanx at the first metatarsophalangeal joint and can be congenital or acquired. Brachymetatarsia is defined as shortening of the metatarsal bones. A combination of hallux varus and brachymetatarsia is rare. A 15-year-old girl presented to our outpatient clinic complaining of problems with her feet. A distinctive hallux varus was present bilaterally combined with a brachymetatarsia of the first metatarsals. The patient reported discomfort. She was restricted in her activities and had severe psychological strain owing to the deformity. We decided on surgery. First, a Pennig MiniFixator for callus distraction of the first metatarsal bone was applied. Owing to the increased plantar subluxation of the phalanx during distraction, an extension of the external fixator was administered so that the hallux could be repositioned to a physiologically satisfying position. After sufficient callus formation, the hardware was removed 14 weeks after surgery. Thereafter, the phalanx moved back to the subluxed position. Finally, an arthrodesis of the first metatarsophalangeal joint was performed with a locking plate. Surgery should not be made only for cosmesis and associated psychological aspects; but, discomfort should be the deciding factor. The postoperative clinical and cosmetic results in our case were good, and the patient was quite satisfied. There was no longer any preoperative discomfort and pain.
