Most patients can be positioned prone for this procedure, except for those with fractures associated with anterior loose bodies and those with neck fractures requiring reduction, which are both amenable to lateral positioning<sup>1</sup>. The feet are positioned off the end of the bed in a neutral position with room to plantar flex and dorsiflex the ankle freely for reduction maneuvers. Following induction of anesthesia and positioning of the patient, the fluoroscopic screen and arthroscopy equipment are positioned on the side opposite the surgeon. A mini C-arm is utilized for the fluoroscopy. The team may then proceed with preparing and draping the surgical field. The surgeon proceeds with creating posteromedial and posterolateral portals to view the fracture site. For talar neck fractures, we utilize standard posterolateral and posteromedial portals directly adjacent to the Achilles tendon at the level of the tip of the medial malleolus, which have previously been established as safe with respect to neurovascular structures<sup>4</sup>. Of note, for talar body fractures these portals are placed slightly more distal at the level of the distal fibula, allowing the screws to be placed perpendicular to the fracture site. An accessory sinus tarsi portal can be established if further reduction to correct varus is needed. The flexor hallucis longus tendon serves as a landmark throughout the case to maintain orientation. We prefer to utilize a 1.9-mm malleable arthroscopic NanoScope (Arthrex), which maximizes our view in the small subtalar space and allows for visualization over the talar dome. A shaver is then utilized to clear out the deep joint capsule and remove fracture hematoma. In our experience, after the initial primary reduction attempt by the orthopaedic trauma provider, the fracture is relatively stable and often held by an external fixator. The remaining reduction is performed with use of manipulation of the ankle in combination with an accessory sinus tarsi portal, utilizing an elevator or a small reduction tool in 1 of the posterior portals.

However, posterior decompression or instrumentation often necessitates patient repositioning, which is associated with increased operative time and time under anesthesia 1–3 . The single-position prone transpsoas approach is a technique that allows surgeons to access both the anterior and posterior aspects of the spine, bypassing the need for intraoperative repositioning and therefore optimizing efficiency 4 . The use of robotic assistance allows for decreased radiation exposure and increased accuracy, both with placing instrumentation and navigating the lateral corridor. Description: The patient is placed in the prone position, and pedicle screws are placed prior to interbody fusion. Pedicle screws are placed with robotic guidance. After posterior instrumentation, a skin incision for LLIF is made in the cephalocaudal direction, orthogonal to the disc space, with use of intraoperative (robotic) navigation. Fascia and abdominal muscles are incised to enter the retroperitoneal space. Under direct visualization, dilators are placed through the psoas muscle into the disc space, and an expandable retractor is placed and maintained with use of the robotic arm. Following a thorough discectomy, the disc space is sized with trial implants. The expandable cage is placed, and intraoperative fluoroscopy is utilized to verify good instrumentation positioning. Finally, posterior rods are placed percutaneously. Alternatives: An alternative surgical approach is a traditional LLIF with the patient beginning in the lateral position, with intraoperative repositioning from the lateral to the prone position if circumferential fusion is warranted. Additional alternative surgical procedures include anterior or posterior lumbar interbody fusion techniques. Rationale: LLIF is associated with reported advantages of decreased risks of vascular injury, visceral injury, dural tear, and perioperative infection 5,6 . The single-position prone transpsoas approach confers the added benefits of reduced operative time, anesthesia time, and surgical staffing requirements 7 . Other potential benefits of the prone lateral approach include improved lumbar lordosis correction, gravity-induced displacement of peritoneal contents, and ease of posterior decompression and instrumentation 8–11 . Additionally, the use of robotic assistance offers numerous benefits to minimally invasive techniques, including intraoperative navigation, instrumentation templating, a more streamlined workflow, and increased accuracy in placing instrumentation, while also providing a reduction in radiation exposure and operative time. In our experience, the table-mounted LLIF retractor has a tendency to drift toward the floor—i.e., anteriorly—when the patient is positioned prone, which may, in theory, increase the risk of iatrogenic bowel injury.

Treatment of this disorder requires restoration of normal mechanical axis alignment and joint orientation, for which it is important to assess whether the deformity arises from the distal femur, knee joint, or proximal tibia. Most commonly, the deformity originates from the distal femur, and various osteotomies of the distal femur have been described 1–6 . The presently described wedgeless V-shaped osteotomy 7,8 is a good option among the various alternative procedures listed below. Description: The anesthetized patient is placed in the supine position on a radiolucent operating table. A bolster is placed beneath the knee to relax the posterior structures. A medial longitudinal skin incision is made that extends from the level of the medial joint line to 5 cm proximal to the adductor tubercle. The vastus medialis is identified and elevated anteriorly by detaching it from its distal and posterior aspects. The leash of vessels underneath the vastus medialis is identified, and the apex of the V-shaped osteotomy is kept just proximal to it. The anterior arm of the V is kept longer than the posterior one, both of them are kept perpendicular to each other, and the apex of the V is made to point distally. The osteotomy is performed on the medial cortex with use of an oscillating saw or multiple drill holes that are then connected using a thin osteotome. Care is taken not to utilize a saw or drill on the lateral cortex. A gentle valgus thrust is applied to break the lateral cortex without periosteal disruption. The apex of the V osteotomy on the proximal fragment is trimmed, and the deformity is corrected with varus force. The osteotomy site is stabilized with use of an anatomically contoured distal medial femoral locking plate or a medial proximal tibial L-shaped buttress plate (of the contralateral side). The implant position is verified under a C-arm image intensifier. The wound is closed in layers over a suction drain in a standard manner. Alternatives: Various types of corrective osteotomies of the distal femur have been described in the literature, including the lateral opening wedge, medial closing wedge, dome, and spike osteotomies 1–6 . All of these procedures have certain limitations and shortcomings. Rationale: The wedgeless V-shaped osteotomy is another described procedure that is inherently stable 7,8 . It is a safe procedure and yields good clinical outcomes 8,9 . The posterior arm of the V-shaped osteotomy is kept smaller than the anterior arm. The proximal cortical bone is allowed to dig into the cancellous bone of the wider distal metaphysis during deformity correction. Trimming the apex of proximal bone end after making the osteotomy facilitates the process.

It is widely agreed that radial neck fractures with angulation of >30° should be reduced. Various maneuvers have been described, but none uniformly achieves complete reduction in severely displaced radial neck fractures (Types III and IV) 1–4 . The aim of the present technique is to achieve closed reduction in these severely displaced radial neck fractures without surgical instrumentation. Description: A stepwise approach is described. First, the radial head is viewed in profile under an image intensifier so that it appears rectangular. Varus stress is applied at the medial aspect of the elbow by the assistant, and thumb pressure is applied at the radial head along the posterolateral aspect of the elbow. This results in partial reduction of the radial head. The elbow is then simultaneously flexed and pronated with continuous pressure over the radial head. This final step anatomically reduces the radial head, and hyperpronating the forearm locks it in the corrected position. Alternatives: Operative alternatives to this technique include intra-focal pin-assisted reduction to achieve closed reduction, the Métaizeau technique of achieving indirect closed reduction of the fracture with the aid of a TENS (Titanium Elastic Nailing System) nail, and open reduction 5 . Nonoperative techniques have also been described for use with Judet Type-II and III fractures, but not with the severely displaced types described in the present article. Rationale: This technique takes into consideration the anatomy of the capsule and lateral collateral ligament complex. The biomechanical ligamentotaxis helps in achieving anatomic reduction of the radial head. Placing the forearm in pronation tightens the annular and lateral collateral ligaments and prevents redisplacement. There are potential complications with operative treatment, including the risk of nerve injury with percutaneous reduction techniques and the risks of osteonecrosis, premature epiphyseal fusion, and heterotopic ossification with open reduction. These complications can be avoided by the use of the presently described technique. Expected Outcomes: This technique provided satisfactory clinical outcomes in our previous study 6 , with none of the 10 patients showing signs of growth disturbance, loss of reduction, or reported complications at 12 months. Terminal restriction of supination was observed in 1 patient. No patient had osteonecrosis or elbow deformity. No patient required conversion to an implant-assisted or open reduction procedure.

Description: The presently described technique is generally utilized in cases in which there is an irreparable disruption of the scapholunate ligament and widening of the scapholunate junction with no carpal arthritis. Alternatives: Other treatment options for irreparable scapholunate dissociation include various forms of capsulotenodesis, bone-ligament-bone reconstruction, tendon-based reconstructions, partial wrist arthrodesis, and proximal row carpectomy. Rationale: The modified Brunelli reconstruction is indicated for a nonrepairable complete scapholunate ligament injury with a reducible rotatory subluxation of the scaphoid, without cartilage degeneration. The dorsal scapholunate ligament is reconstructed and the distal palmar scaphoid rotation is corrected with use of a distally based flexor carpi radialis tendon. The reconstruction is achieved by placing the flexor carpi radialis tendon through a transosseous scaphoid tunnel and weaving the tendon through the dorsal ulnar capsule or radiotriquetral ligament.

Description: The procedure is performed with the patient under general anesthesia and on a radiolucent table in order to allow for intraoperative fluoroscopy. The procedure is performed through small incisions made over the vertebral levels of interest, typically utilizing either a fixed or expandable type of tubular dilator, which is eventually seated against the facet joint complex 4 . A laminectomy and/or facetectomy is performed in order to expose the disc space, and the ipsilateral neural elements are visualized 5 . The end plates are prepared, and an interbody device is placed after the disc is removed. Pedicle screws and rods are then placed for posterior fixation. Alternatives: Nonoperative alternatives include physical therapy and corticosteroid injections. Other operative techniques include open TLIF or other types of lumbar fusion approaches, such as posterior lumbar interbody fusion (PLIF), anterior lumbar interbody fusion, lateral or extreme lateral interbody fusion, or oblique lumbar interbody fusion. Rationale: Open TLIF was developed in order to obtain a more lateral approach to the lumbar disc space than was previously possible with PLIF. The goal of this was to minimize the amount of thecal-sac and nerve-root retraction required during PLIF 4 . Additionally, as the number of patients who required revision after PLIF increased, the need arose for an approach to the lumbar spine that circumvented the posterior midline scarring from previous PLIF surgical sites 6 . MI-TLIF was introduced to reduce the approach-related paraspinal muscle damage of open TLIF 5 . Indications for MI-TLIF include most degenerative pathology of the lumbar spine, including disc herniation, low-grade spondylolisthesis, and spinal and foraminal stenosis 7 . However, MI-TLIF allows for less robust correction of deformity than other minimally invasive approaches; therefore, MI-TLIF may not be as effective in cases of substantial spinal deformity or high-grade spondylolisthesis 8 . Expected Outcomes: MI-TLIF results in significantly less blood loss, postoperative pain, and hospital length of stay compared with open TLIF 1–3 . Although some studies have suggested increased operative time for MI-TLIF 9,10 , meta-analyses have shown comparable operative times between the 2 techniques 1–3 . It is thought that the discrepancy in reported operative times is the result of a learning curve and that, once that is overcome, the difference in operative time between the 2 techniques becomes minimal 11,12 .

Much research has been dedicated to finding solutions that offer balance in terms of the strength and ease of the repair versus the rate of complications such as adhesions. The number of core sutures, distance from the tendon edge, and use of an epitendinous stitch have been shown to affect repair strength 1–4 . A number of configurations have been described for the placement of the suture; however, none has been identified as a clear gold standard 5 . This article will highlight the preferred tendon repair technique of the senior author (R.J.S.), the Strickland repair with a simple running epitendinous stitch. Relevant anatomy, indications, operative technique, and postoperative management will be discussed. Description: The flexor tendon is typically accessed via extension of the laceration that caused the initial injury. After the neurovascular structures and pulleys are assessed, the tendon is cleaned and prepared for repair. A 3-0 braided nylon suture is utilized for the 4-core strand repair and placed in the Strickland fashion. A 5-0 polypropylene suture is then utilized for the simple running epitendinous stitch. Alternatives: Multiple alternative techniques have been described. These vary in the number of core strands, the repair configuration, the suture caliber, and the use of an epitendinous or other suture. Nonoperative treatment is typically reserved for partial flexor-tendon laceration, as complete tendon discontinuity will not heal and requires surgical intervention. Rationale: The 4-core strand configuration has been well established to increase the strength of the repair as compared with 2-core strand configurations, while also being easier to accomplish and with less suture burden than other techniques 1 . The presently described technique has excellent repair strength and can allow for early active range of motion, which is critical to reduce the risk of postoperative adhesions and stiffness. Expected Outcomes: Excellent outcomes have been demonstrated for primary flexor-tendon repair if performed soon after the injury 1,2,6,7 . Delayed repair may lead to adhesions and poor tendon healing 8 . Early postoperative rehabilitation is vital for success 9 . There are advocates for either active or passive protocols 10–12 . The protocol at our institution is to begin early active place-and-hold therapy at 3 to 5 days postoperatively, which has been shown in the literature to provide improved finger motion as compared with passive-motion therapy 13–16 . Important Tips: The proximal end of the tendon may need to be retrieved via a separate incision if it is not accessible through the flexor-tendon sheath. The proximal end of the tendon may be held in place with a 25-gauge needle in order to best place sutures into both ends of the tendon. The epitendinous suture is run around the back wall before the core sutures are tied down, in order to p","PeriodicalId":44676,"journal":{"name":"JBJS Essential Surgical Techniques","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135954744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
