Extensive implant reaction in failed subtalar joint arthroereisis: report of two cases.

Foreign body synovitis with extensive granulomatous giant cell reaction to refractile polyethelene debris is a complication of subtalar arthroereisis not previously reported. We present two cases whereby STA-peg implants were used to treat bilateral painful flexible flatfoot deformities in children. Two boys, presented at 7 and 10 years of age, 2 years after STA-peg procedures and tendo-Achilles lengthening for painful flatfeet.

Clinical tips: retrograde drilling of talar osteochondral defects.

Contemporary methods of bone grafting osteochondral defects, in which the remaining overlying cartilage is relatively well preserved, have inherent problems. The bony defects are often saucer-shaped and the cylindrical graft may not fill the void, leaving areas of cartilage with no underlying scaffold and obviating early weight bearing. Furthermore, to obtain a proper fill of the defect, tamping of the graft can cause excessive pressure and disruption of the overlying cartilage.

The frequency of digital artery resection in Morton interdigital neurectomy.

Background: Operative strategies used in resecting the digital nerve in Morton neuroma emphasize retaining the digital artery. Concern over inadvertent resection of the digital vessel has prompted many surgeons to avoid adjacent interdigital neurectomies when more than one nerve is affected.

Methods: The current study examined 674 consecutive pathologic specimens obtained after neurectomy.

Observations on the fibrous retinacula of the heel pad.

Background: The original purpose of the study was to clarify whether or not there is continuity of the Achilles tendon and the plantar fascia. Those findings have been previously published. In the course of that study, observations of the anatomy of the retinacular tethers of the heel pad were made.

Outcomes after standardized screw fixation technique of ankle arthrodesis.

Several methods of obtaining ankle fusion have been described, with numerous studies reporting on patient populations with varied diagnoses and various methods of fixation. This has led to outcome analyses that are difficult to interpret. Our hypothesis is that using a standard method of fusion, without the aid of allograft, a solid ankle fusion can be achieved in patients with end-stage ankle arthritis, and that this outcome can be reflected in standardized outcome tools.

Outcomes after interposition arthroplasty for treatment of hallux rigidus.

Unlabelled: Interposition arthroplasty reportedly improves outcomes after traditional salvage procedures for advanced hallux rigidus. We hypothesized this procedure can provide pain relief and satisfactory function with few complications. We examined 18 patients with severe articular cartilage loss who received 21 interposition arthroplasties.

An analysis of talar surface area occupied by screw fixation in ankle fusions.

Background: Ankle arthrodesis remains the benchmark of treatment for end-stage arthrosis of the ankle joint. Despite that, the incidence of nonunion can be as high as 15%. Various strategies have been used to reduce the incidence of nonunion, including multiple compression screws and larger diameter screws to improve mechanical stability and compression.

An analysis of outcome measures following the Broström-Gould procedure for chronic lateral ankle instability.

Background: The Broström-Gould procedure is a commonly recommended operative treatment for chronic ankle instability. Using standardized physician-based outcome scores, the results of this procedure have been uniformly excellent. Current scoring systems, however, do not adequately evaluate mechanical or functional instability.
