ABSTRACT
Peroneal subluxation is a rare but debilitating pathology that can be the result of a superior peroneal retinaculum tear or intrasheath laxity. On clinical examination of both cases, the pathology is observed when the ankle is circumducted in eversion and dorsiflexion. With a superior peroneal retinaculum tear, the tendons dislocate from the peroneal groove, whereas with intrasheath laxity the tendons remain in the groove. In the present case series, peroneal stabilization was performed for both superior peroneal retinaculum tear and intrasheath laxity. With our technique, the fibro-osseous connections of the peroneal tendon sheath are detached from the distal one third of the fibula. Drill holes are made through the fibula for suture to be passed through and the peroneal tendon sheath is reattached to the fibula through horizontal mattress sutures via pants over vest technique to restore tension to the sheath. A total of 5 patients underwent peroneal stabilization, 100% (5/5) of which had preoperative pain with palpation along the peroneal tendons and a palpable click with range of motion of the ankle joint. Postoperatively, 100% (5/5) of the patients were fully weight-bearing, compared to 60% (3/5) preoperatively. No patients had residual subluxation of the peroneal tendons postoperatively or a need for revisional surgery. Residual peroneal tendonitis was present in 20% (1/5) of patients and sural neuritis occurred in 20% (1/5) of patients. The peroneal tendons are physiologically tightened within the peroneal tendon sheath to mitigate the pathologic subluxation, without sacrificing tendons for transfer or using allograft material.Clinical Level of Evidence: Therapeutic, Case Series, Level 4.

Retrocalcaneal exostosis can be debilitating and in severe cases, surgical resection is indicated. Complications can arise from surgical resection of the exostosis and reattachment of the Achilles tendon, including irritation of the suture knot, recurrence of the bony prominence, and dehiscence. The use of a buried knot technique with functional lengthening of the Achilles tendon and gastroc-soleal muscle complex can minimize these complications. Complete detachment of the Achilles tendon allows for aggressive and thorough resection of the exostosis and functional lengthening with reattachment. The buried cruciate knot technique allows for firm reattachment with buried knots to prevent soft tissue irritation. A total of fourteen patients (14 limbs) underwent retrocalcaneal enthesophyte resection with functional Achilles tendon lengthening, (8/14) of which had difficultly wearing shoe gear, (10/14) had edema, and (2/14) had erythema preoperatively. Postoperatively, (11/14) of patients returned to full activities and sports, and (11/14) returned to normal shoe gear. Complications included (1/14) of patients with Achilles tendon avulsion and (3/14) of patients with surgical site dehiscence requiring revisional surgery. Overall, this technique helps prevent short-term complications and long-term recurrence due to the functional lengthening mitigating insertional forces on the Achilles tendon.

Subtalar joint arthroscopy can be performed on a wide array of pathology. The procedure has progressed from a diagnostic test to a reconstructive procedure. Although it is not as popular as ankle arthroscopy, it is becoming more commonly discussed in the literature and is part of many arthroscopy courses. Better education along with improved instrumentation will allow more foot and ankle surgeons to treat pathology of the subtalar joint with arthroscopic techniques. This will lead to improved outcomes and lower complication rates in treating that pathology.

The purpose of this study was to assess 7 methods of fixation for a midtarsal osteotomy. Polyurethane foam models (N = 6) and cadaver specimens (N = 4-7) were used to examine the force generated by the different constructs of fixation. A midtarsal osteotomy was performed on each specimen in the test groups. The osteotomies were fixated either with 2 parallel 0.062-in Kirschner wires and 40-mm-long, 4-mm partially threaded, cancellous, cannulated titanium screws, an external ring fixator (frame), a frame with wires tensioned (tension), a frame with wires tensioned and compressed toward the osteotomy (tension and compression), a frame with tension, compression, and parallel Kirschner wires, or a frame with tension, compression, and two 4.0 cannulated parallel screws, respectively. Each model was fixated, and the force generated by the construct across the osteotomy was recorded via the use of pressure-sensitive film. Statistical analysis of the data in the polyurethane foam group determined that the use of frame with tension, compression, and two 4.0 parallel cannulated screws was statistically superior to 1) frame, 2) frame with tension, 3) 2 parallel Kirschner wires, 4) two 4.0 cannulated parallel screws, and 5) frame with tension and compression. A cadaver study determined that the frame with tension, compression, and 2 parallel Kirschner wires was statistically superior to 1) frame and 2) two parallel Kirschner wires. These findings suggest that there is a difference in the force generated by the type of fixation construct across a midtarsal osteotomy.
