Management of Chronic Exertional Compartment Syndrome of the Foot: A Report of 3 Cases.

BACKGROUND: Arch pain in athletes is a common complaint with many causes. One uncommon cause of arch pain related to exercise that is often overlooked is chronic exertional compartment syndrome. This diagnosis should be considered in athletes who presents with exercise-induced foot pain. Recognition of this problem is paramount because it can significantly affect an athlete's ability to pursue further sports activities. METHODS: Three case studies are presented that underscore the importance of a comprehensive clinical evaluation. Unique historical information and findings on focused physical examination after exercise strongly suggest the diagnosis. RESULTS: Intracompartment pressure measurements before and after exercise are confirmatory. Because nonsurgical care is typically palliative, surgery involving fasciotomy to decompress involved compartments can be curative and is described in this article. CONCLUSIONS: These three cases with long-term follow-up were randomly chosen and are representative of the authors' combined experience with chronic exertional compartment syndrome of the foot.

Postoperative Infection Rates After Total Ankle Arthroplasty: A Comparison With and Without the Use of a Surgical Helmet System.

Following total joint arthroplasty, surgical site infections (SSI) and periprosthetic joint infections (PJI) are associated with increased patient morbidity and healthcare utilization. Current positive-pressure surgical sterile helmet system (SHS) were developed as a feasible, useful version of the body exhaust system.The use of SHS has not yet been proven to decrease infection rates in the orthopedic literature. The primary purpose of this study is to compare the infection rates between patients who underwent total ankle arthroplasty (TAA) with a surgical team wearing SHS versus without SHS.A retrospective chart review in patients undergoing primary TAA with the surgeon wearing SHS (Group 1) or standard surgical attire (Group 2) was conducted. The primary outcome was postoperative SSI and PJI. The rate of wound complications, revision rates, and associated procedures were also analyzed. We identified 109 patients in Group 1 and 151 patients in Group 2. The rate of SSI was 12.8% in Group 1 and 14.6% in Group 2 (p = .411). The rate of PJI was 0.92% in Group 1 and 2.6% in Group 2 (p = .411). There was no difference in revision rates between the two groups. This study suggests that SHS does not appear to protect against postoperative SSI or PJI after TAA. Conversely, we did not find a higher infection rate compared to standard surgical attire despite recent in-vitro studies suggesting SHS as a source of wound contamination. The utility of SHS does not appear to influence the prevalence of postoperative SSI or PJI.

A Comparison of Outcomes of Revision Surgical Options for the Treatment of Failed Bulk Talar Allograft Transfer: A Systematic Review.

Talar bulk osteochondral allograft transplantation is a useful treatment strategy for large, uncontained osteochondral lesions of talus. Complications and high revision rates from osteochondral talar allograft transfer can be common. Talar graft failure is a devastating complication that results from failure of allograft incorporation within the host bone and subsequent resorption and sometimes subsidence can occur. Treatment options and outcomes for graft failure have rarely been reported. The purpose of this study is to evaluate treatment options and their outcomes for treating talar allograft failure. A systematic review was completed to find all reports of salvage treatments for talar graft failure and outcomes of these reports were analyzed. Eleven studies involving a total of 522 ankles, in 520 patients, met the inclusion criteria. The allograft failure rate was 11.5% in these studies with a reoperation rate of 18.9%. With limited reports, satisfactory outcomes for treatment of graft failure with ankle arthrodesis were 77.3%, 50% for revision allograft procedures, and 50% for total ankle arthroplasty. Considering the large failure rate and reoperation rate for bulk talar allograft transplantations, superior revision, and salvage options are needed. More prospective cohort studies focusing on consistent and standard outcome measures are needed to further assess revision options for failed talar allograft procedures.

Complications of En Bloc Osteochondral Talar Allografts and Treatment of Failures: Literature Review and Case Report.

Reoperation rates and complication rates can be high for patients receiving an osteochondral talar allograft transplant. Complications can include graft failure, delamination of the graft, arthrofibrosis, advancing osteoarthritis, nonunion of malleolar osteotomies, and partial or complete osteonecrosis of the talus. Graft failure refers to failure of graft incorporation with subsequent necrosis and subsidence. Treatment options for talar graft failure are limited, and outcomes for these treatments have rarely been reported. We present a review of the published data on the complications and treatments for failed talar allograft transplantation. A case report is presented on a young woman who experienced graft failure and osteonecrosis of her talar allograft transplant. Because of the size of the present osteonecrosis, an ankle arthrodesis was performed as the initial revision procedure. Talar necrosis was removed and revascularized from the ankle fusion with solid fusion was confirmed with computed tomography. Symptomatic adjacent joint pain quickly developed in the hindfoot after the ankle fusion, and 12 months later an ankle fusion conversion to total ankle arthroplasty was performed. The patient has returned to normal activity with significant reduction in pain at most recent follow-up visit. This patient was followed for 7 years from initial osteochondral talar allograft transplantation and for 2 years from conversion of ankle fusion to total ankle arthroplasty. It is important to understand the techniques, indications, and outcomes for the various revision options for talar allograft failure. This case report illustrates how multiple revision options can be used to provide the best outcome for the patient.

Takedown of Ankle Arthrodesis With Insufficient Fibula: Surgical Technique and Intermediate-Term Follow-Up.

Conversion of ankle arthrodesis to total ankle arthroplasty has recently gained popularity. However, technical challenges are present when treating patients without a sufficient fibular buttress. We describe a technique for restoration of an adequate fibular buttress using an iliac crest bone graft or malleolar relocation. The results of 10 patients with an average follow-up period of 56 (range 24 to 123) months are presented. Of the 10 patients, 3 underwent tricortical iliac bone augmentation of the fibula, 4 underwent repositioning of the remnant fibula, and in 3, the in situ fibula was used. The average interval from fusion to takedown was 15.1 (range 5 to 35) years, and the average age at takedown was 52.8 (range 33 to 75) years. The average improvement in the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale and Buechel-Pappas scale scores was 35.8 (range 30 to 46) and 34 (range 25 to 42), respectively. Three patients underwent a total of 7 subsequent operations related to the ankle implant. Only 1 of the patients had any residual frontal plane deformity. None of the patients exhibited any component subsidence; however, 2 patients experienced asymptomatic lateral talar component overgrowth. The improvement in the clinical scores in this group of patients suggests that takedown of an ankle arthrodesis with an insufficient fibula is a viable option to improve function. Various techniques to restore the lateral buttress can be used even with complete absence of the distal fibula.

Plate Fixation With Autogenous Calcaneal Dowel Grafting Proximal Fourth and Fifth Metatarsal Fractures: Technique and Case Series.

Metaphyseal and proximal diaphyseal fractures of the lateral column metatarsals can have problems with healing. In particular, those involving the fifth metatarsal have been associated with a high nonunion rate with nonoperative treatment. Although intramedullary screw fixation results in a high union rate, delayed healing and complications can occur. We describe an innovative technique to treat both acute and chronic injuries involving the metatarsal base from the metaphysis to the proximal diaphyseal bone of the fourth and fifth metatarsals. The surgical technique involves evacuation of sclerotic bone at the fracture site, packing the fracture site with compact cancellous bone, and plate fixation. In our preliminary results, 4 patients displayed 100% radiographic union at a mean of 4.75 (range 4 to 6) weeks with no incidence of refracture, at a mean follow-up point of 3.5 (range 1 to 5) years. The early results with our small series suggest that this technique is a useful treatment choice for metaphyseal and proximal diaphyseal fractures of the fourth and fifth metatarsals.

Total Ankle Replacement with Severe Valgus Deformity: Technique and Surgical Strategy.

Correction of severe valgus deformity of the foot and ankle with ankle replacement is challenging. We describe the controversies and specific issues of surgical management and provide a detailed surgical strategy for management of this common deformity. A reliable technique for deltoid reconstruction is also described and illustrated in detail.
