I'm having a difficult time coding this same scenario myself. J Foot Ankle Surg. There are two general ways of doing a lateral column lengthening, both of which involve taking a bone graft and inserting it into the lateral column. Flatfoot deformity with medial arch collapse. [Medial flexor digitorum longus tendon augmentation and lateral foot column lengthening or reorienting triple arthrodesis as surgical therapy of posterior tibial tendon dysfunction]. Adult acquired flatfoot deformity 2B: Dissect laterally over the anterior calcaneus, from a point adjacent to the calcaneocuboid joint to the level of the posterior facet. This pushes the foot into a straighter position. The typical amount of lengthening of the lateral column is between 5 and 10 mm. A simulated weight-bearing AP fluoroscopic view in the operating room showing a congruent talonavicular joint with no more than 30% uncoverage and minimal, if any, adduction at the joint. This site needs JavaScript to work properly. Please enable it to take advantage of the complete set of features! Hold the osteotomy open to the desired amount of lengthening and fashion a tricortical allograft to fit that space. Therefore, the lateral column lengthening procedure involves lengthening this region. Careers. For the next 4-6 weeks (assuming the bone graft has healed), the patient can weight bear as tolerated in acast boot. Please enable it to take advantage of the complete set of features! Lateral column lengthening (Evans Osteotomy) for adult acquired flatfoot is a surgical procedure designed to modify the shape of the foot and create an arch. Clinically, there should be near-normal eversion motion remaining, but mild stiffness is acceptable (Fig. 26.2 Goals of Surgical Procedure Note: Any of these options may help symptoms and possibly slow down progression, but they do not halt progression. Volkering C, Erne H, Altenberger S, Walther M. Orthopade. 26.1 Incisions for lateral column lengthening (LCL; green) and posterior calcaneal osteotomy (red). The successful patient has near-normal eversion motion remaining in the hindfoot, and good alignment of the heel. Sands A, Early J, Harrington RM, Tencer AF, Ching RP, Sangeorzan BJ. Also, look for possible sags at naviculocuneiform and first tarsometatarsal joints on the standing lateral X-ray. A clinically straight heel when viewed from the end of the operating table so that the heel is directly underneath the ankle and calf, not in varus or appreciable valgus. In a click, check the DRG's IPPS allowable, length of stay, and more. Fashion the graft according to the ideal amount of correction as shown by looking at the osteotomy held open to the desired amount. These joints are important for the patient being able to exercise on the foot and minimize the risk of ankle arthritis over time. Adolescent flexible flatfoot. LRR can be performed as an isolated procedure or as an associated procedure. This site needs JavaScript to work properly. In an osteoporotic patient with significantly weak bone, an Evans procedure is preferable to a step-cut osteotomy (see section Lateral Column Lengthening Alternative Procedure: Step-cut Osteotomy) because of less chance of fracturing the bone with manipulation. with or without lengthening, shortening or angular correction, metatarsal; first metatarsal 28310 Osteotomy, shortening, angular or rotational correction; proximal phalanx, first toe . With the graft in place and pinned, confirm that the amount of correction is appropriate and that both clinical inspection and fluoroscopic views show good apposition of the graft to the native bone. The lateral column is made up of the calcaneus, the cuboid, and the fourth and fifth metatarsals. An official website of the United States government. Abstract. Subperiosteal dissection was carried out over the calcaneocuboid joint. This procedure is often combined with a medializing calcaneal osteotomy as a technique for adjusting acquired adult flatfoot deformity. Background Lateral column lengthening calcaneal osteotomy is a powerful procedure for correcting forefoot abduction in flatfoot deformity. Epub 2017 Apr 10. If, on a simulated AP weight-bearing view with the eversion stress, there is adduction at the talonavicular joint or there is almost no eversion in the hindfoot, the foot is overcorrected. Lateral column lengthening is a powerful procedure performed either with an Evans calcaneal osteotomy or calcaneocuboid distraction arthrodesis that can be used as an adjunct in realigning the flatfoot. Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)Click to share on Google+ (Opens in new window) PROCEDURE: Radiographically, the abduction should be corrected so that there is a normal amount of uncoverage of the talar head (30% or less), and no adduction of the talonavicular joint. Medial displacement osteotomy os calcis - (confident) 28300 2015 Jun;36(6):705-9. doi: 10.1177/1071100715571439. These findings demonstrate the need for clinical investigation of this procedure, which could preserve motion in the talonavicular and subtalar joints, correct deformity, and obviate calcaneocuboid arthritis. A small bump can be placed under the ipsilateral hip to aid with the lateral column lengthening, although this may make the approach to the PTT more difficult during the tendon transfer procedure if the leg is rotated too internally. For the next 4-6 weeks (assuming the bone graft has healed), the patient can weight bear as tolerated in a cast boot. Foot Ankle Clin. Lengthening the lateral column of the foot has been shown to correct flatfoot deformity. Yin-Chuan Shih, MD . Oh I, Imhauser C, Choi D, Williams B, Ellis S, Deland J. J Bone Joint Surg Am.

Standing plain X-rays can underestimate deformity if patient is not allowing the arch to collapse, the patient is leaning back, or the X-ray is not properly centered over the talonavicular joint. Only gold members can continue reading. 2010 Jun;36(3):196-205. doi: 10.1007/s00068-010-1036-3. The .gov means its official. 26.6.1 Lateral Column Lengthening: Evans Procedure Lateral column lengthening is a useful adjunct to hindfoot arthrodesis in the correction of revision and severe end-stage flatfoot deformity. For the first 6-10 weeks, the patient is either non-weight bearing or limited weight bearing through the heel, until the bone graft has healed. 26.3 Advantages of Surgical Procedure Triple arthrodesis or medial-approach double arthrodesis have been the standard but often do not provide enough correction of the deformity. In cases with more than a little increased heel valgus, it is normally necessary to do a posterior calcaneal osteotomy as well as an LCL to obtain correct position of the heel. Good luck! Beimers L, Louwerens JW, Tuijthof GJ, Jonges R, van Dijk CN, Blankevoort L. Foot Ankle Int. Level of evidence: Level V, consensus, expert opinion. Judge the abduction of the talonavicular joint on the AP foot X-ray and the plantar sag at the talonavicular joint on the lateral X-ray. Autograft and allograft unite similarly in lateral column lengthening for adult acquired flatfoot deformity. When this is achieved, place a pin from the anterior calcaneus across the graft and into the posterior calcaneus. Mosier-LaClair S, Pomeroy G, Manoli A 2nd. The Current Procedural Terminology (CPT ) code 28300 as maintained by American Medical Association, is a medical procedural code under the range - Repair, Revision, and/or Reconstruction Procedures on the Foot and Toes. The site is secure. government site. Operative treatment of the difficult stage 2 adult acquired flatfoot deformity. Special hardware holds the graft and the bone together so they can grow together to form one bone. Radiographically, the abduction should be corrected so that there is a normal amount of uncoverage of the talar head (30% or less), and no adduction of the talonavicular joint. Curr Rev Musculoskelet Med. However, the disadvantages include the potential of creating a stiffer foot; possibly overcorrecting the foot (which may lead to more symptoms); and a higher rate of specific complications, such aspainful hardware,sural nerve irritation, andnonunion. FOIA Zhou H, Ren H, Li C, Xia J, Yu G, Yang Y. Biomed Res Int. 2017;2017:4383981. doi: 10.1155/2017/4383981. Hold the osteotomy open to the desired amount of lengthening and fashion a tricortical allograft to fit that space. Only gold members can continue reading. Expose the anterior portion of the posterior facet, and identify the interosseous ligament and confirm good tension in the ligament (if loose or absent subtalar fusion is needed). Copyright 2018 the American College of Foot and Ankle Surgeons. Dissection continued down through subcutaneous tissues to the calcaneocuboid joint using care to avoid damage to the sural neurovascular bundle. Tags: Foot and Ankle Surgery After lateral column lengthening with calcaneocuboid fusion, 48% of talonavicular and 70% of subtalar joint range of motion were preserved. Epub 2010 May 28. and transmitted securely. Mobilize the peroneal tendons so that they can be retracted with a Bennett retractor to allow a saw cut into the lateral aspect of the anterior calcaneus. Such a patient most often preoperatively does not have subfibular impingement but can certainly have subtalar impingement.

The distance between the calcaneocuboid joint and the articular facet of the subtalar joint was measured by digital calipers for further analysis. Also, on the coronal views of the CT scan, look for lateral subluxation of the subtalar joint, which probably indicates the need for a subtalar fusion. That situation will lead to an unsatisfied patient with lateral weight bearing. , Walther M.
