The etiology of these deformities is often untreated or undercorrected infantile and adolescent Blount disease.

We apply the principles of fixator-assisted acute deformity correction, mostly described for use at the distal aspect of the femur, as well as the principles of anatomic reduction and fixation of proximal-third tibial fractures<sup>4</sup> to acutely correct these complex deformities in skeletally mature individuals<sup>5-12</sup>. We perform acute correction of multiplanar proximal tibial deformity with use of fixator-assisted intramedullary nailing in order to avoid the complications and patient discomfort associated with gradual deformity correction with use of a circular external fixator. This procedure is novel in the treatment of adolescent Blount disease deformity in skeletally mature individuals and can additionally be utilized for other proximal tibial metaphyseal deformities, allowing the accurate and acute correction of all planes of deformity as well as the anatomic and mechanical axes, while avoiding the prolonged use of external fixators.</p><p><strong>Description: </strong>The patient is positioned supine on a radiolucent table.

Mark a 3-cm transverse incision 1 cm distal to the proximal Achilles stump and make the incision, taking care to protect the sural nerve laterally. Next, create a transverse paratenon incision and bluntly dissect it from the Achilles circumferentially. After gaining access to the proximal Achilles stump, clamp it with an Allis clamp and insert the PARS Jig between the Achilles tendon and paratenon, sliding it proximally to the myotendinous junction. To secure the jig to the proximal Achilles tendon, insert a guide pin into the jig position-1 hole. To pass sutures through the Achilles tendon, insert pins with their respective sutures into positions 2 through 5 and insert the FiberTape suture (Arthrex) in position 1. Remove the jig from the transverse incision, pulling the suture ends out of the incision. Once they are out, reorient the sutures on the medial and lateral sides to match their positions when initially placed. On both sides, wrap the blue suture around the 2 striped green-and-white sutures twice, and pull the blue suture through the looped green-and-white suture on the ipsilateral side. After doing that, fold the blue suture on itself to create a shuttling suture with the green-and-white suture. Next, pull on the medial non-looped green-and-white suture until it has been pulled out medially, and repeat that with the lateral non-looped green-and-white suture until it has been pulled out laterally, to create a locking stitch.

A high-resistance nonresorbable suture is sewn with use of a Krackow technique to whipstitch the distal 4 cm of the tendon. Alternatively, 2 sutures (4 strands) can be utilized.

The location of the superior pubic root is identified after making a recess within the anteroinferior capsule. In order to ensure that the appropriate trajectory is obtained, C-arm imaging (inlet view and orthogonal obturator outlet views) is utilized to safely predrill the screw trajectory into the superior pubic ramus. A Kirschner wire (K-wire) is then placed into the hole. With use of a metal-cutting burr on the back table, customized peripheral screw holes are placed and then the acetabular component is slid and impacted into place over the K-wire.

However, in many cases of discontinuity, there may be severe ischial osteolysis, making ischial screw placement difficult or impossible. The superior pubic ramus, however, remains a reliable option that can be utilized for inferior screw fixation, even in cases of severe acetabular bone loss, and thus is especially beneficial in these difficult cases.</p><p><strong>Rationale: </strong>The technique of acetabular distraction was developed because of limitations with alternative techniques.

This procedure requires the use of a \"kickstand\" screw or of inferior screw fixation in order to prevent abduction failure of the cup.

The Kirschner wire is then advanced into the head of the fifth metacarpal, securing the reduction. Malrotation can be addressed in this stage by rotating the wire under fluoroscopic control. After ensuring anatomical reduction clinically and by fluoroscopy, the wire is shortened under the skin, followed by closure of the incision. We utilize a mid-hand brace for splinting.</p><p><strong>Alternatives: </strong>Nonoperative treatment is common for fifth metacarpal neck fractures in the absence of malrotation, excessive angulation, and shortening. Other surgical techniques include a similar procedure that involves the use of multiple Kirschner wires, plate fixation, transverse Kirschner wire pinning, and, less commonly, retrograde headless screw fixation<sup>2,7-9</sup>.</p><p><strong>Rationale: </strong>The main advantage of this technique is the preservation of the metacarpophalangeal joint and the minimal soft-tissue damage. Additionally, the use of a single Kirschner wire provides stability at low cost. With some experience, this surgery can be performed within 20 minutes<sup>1,9</sup>.</p><p><strong>Expected outcomes: </strong>This procedure provides good fracture reduction and stabilization<sup>8</sup>. The outcome is usually satisfactory, with very low Disabilities of the Arm, Shoulder, and Hand scores<sup>1</sup>. Malrotation, angulation, and shortening are sufficiently addressed, and the technique shows the same results as fixation performed with use of 2 intramedullary wires.</p><p><strong>Important tips: </strong>Bending the Kirschner wire to ensure easy gliding in the medullary canal provides the opportunity to reduce the metacarpal neck once the wire is safely in the head.Aim distally as you open the cortical bone with the awl in order to facilitate the insertion of the Kirschner wire.The primary reduction should be made manually, not by the","PeriodicalId":44676,"journal":{"name":"JBJS Essential Surgical Techniques","volume":"12 2","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9889294/pdf/jxt-12-e20.00050.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10661215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This allows the prosthesis to be skeletally anchored, eliminating socket-related problems such as tissue compression that can provoke neurogenic pain, skin abrasion, and fitting problems resulting from residual limb size fluctuation<sup>1</sup>. Amputees with osseointegrated prostheses typically wear their prosthesis more and experience better mobility, quality of life, and extremity proprioception compared to those with socket prostheses<sup>2-4</sup>.</p><p><strong>Description: </strong>We demonstrate the fundamentals of a single-stage procedure involving an impacted press-fit porous-coated titanium osseointegration implant. The preoperative evaluation is summarized and the specific surgical steps are described: exposure, osteotomy, canal preparation, implant insertion, (optional) targeted muscle reinnervation, muscle closure, soft-tissue contouring and stoma creation, and abutment insertion.</p><p><strong>Alternatives: </strong>Amputees who are dissatisfied with their quality of life or mobility when using a socket prosthesis can attempt to modify their socket or activity level or accept their situation.

In a recent study<sup>2</sup> of 18 femoral and 13 tibial amputees who had osseointegration, Reif et al. showed significant improvements in prosthesis wear time, mobility, and multiple quality-of-life surveys at a mean follow-up of nearly 2 years. The most common postoperative complication for this procedure is low-grade soft-tissue infection, which is usually managed by a short course of oral antibiotics. Much less often, soft-tissue debridement or implant removal may be needed to manage infection. Periprosthetic fractures can nearly always be managed with familiar fracture fixation techniques and implant retention<sup>6</sup>.</p><p><strong>Important tips: </strong>Template","PeriodicalId":44676,"journal":{"name":"JBJS Essential Surgical Techniques","volume":"12 2","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/27/07/jxt-12-e21.00068.PMC9889284.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10661216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
