Recommendation: There is evidence indicating that the amount of bony correction performed in the setting of progressive collapsing foot deformity reconstructive surgery can be titrated within a recommended range for a variety of procedures. The typical range when performing a medial displacement calcaneal osteotomy should be 7 to 15 mm of medialization of the tuberosity. The typical range when performing an Evans lateral column lengthening should be 5 to 10 mm of a laterally based wedge in the anterior calcaneus. The typical range when performing a plantarflexion opening wedge osteotomy of the medial cuneiform (Cotton) osteotomy should be 5 to 10 mm of a dorsal wedge. Level of Evidence: Level V, consensus, expert opinion.

Consensus Expert

Recommendation: Forefoot varus is a physical and radiographic examination finding associated with the Progressive Collapsing Foot Deformity (PCFD). Varus position of the forefoot relative to the hindfoot is caused by medial midfoot collapse with apex plantar angulation of the medial column. Some surgeons use the term forefoot supination to describe this same deformity (see Introduction section with nomenclature). Correction of this deformity is important to restore the weightbearing tripod of the foot and help resist a recurrence of foot collapse. When the forefoot varus deformity is isolated to the medial metatarsal and medial cuneiform, correction is indicated with an opening wedge medial cuneiform (Cotton) osteotomy, typically with interposition of an allograft bone wedge from 5 to 11 mm in width at the base. When the forefoot varus is global, involving varus angulation of the entire forefoot and midfoot relative to the hindfoot, other procedures are needed to adequately correct the deformity. Level of Evidence: Level V, consensus, expert opinion.

We present a technical surgical description of a 36-year-old female diagnosed with Progressive Collapsing Foot Deformity (PCFD) treated with a medial displacement calcaneus osteotomy, a lateral column lengthening, and a modified Lapidus fusion. In order to increase the plantar flexion power of this arthrodesis and minimize the loss in ray length with joint preparation, a bone block structured graft was used. Fixation was performed using a post implant in the medial cuneiform with crossing screws though the surfaces and the graft. Forefoot varus was properly corrected intraoperatively by using the described surgical technique. Satisfactory functional short-term results and an excellent alignment was accomplished.

Important Sign

Recommendation: Progressive collapsing foot deformity (PCFD) is a complex 3D deformity with varying degrees of hindfoot valgus, forefoot abduction, and midfoot supination. Although a medial displacement calcaneal osteotomy can correct heel valgus, it has far less ability to correct forefoot abduction. More severe forefoot abduction, most frequently measured preoperatively by assessing talonavicular coverage on an anteroposterior (AP) weightbearing conventional radiographic view of the foot, can be more effectively corrected with a lateral column lengthening procedure than by other osteotomies in the foot. Care must be taken intraoperatively to not overcorrect the deformity by restricting passive eversion of the subtalar joint or causing adduction at the talonavicular joint on simulated AP weightbearing fluoroscopic imaging. Overcorrection can lead to lateral column overload with persistent lateral midfoot pain. The typical amount of lengthening of the lateral column is between 5 and 10 mm. Level of Evidence: Level V, consensus, expert opinion. CONSENSUS STATEMENT ONE: Lateral column lengthening (LCL) procedure is recommended when the amount of talonavicular joint uncoverage is above 40%. The amount of lengthening needed in the lateral column should be judged intraoperatively by the amount of correction of the uncoverage and by adequate residual passive eversion range of motion of the subtalar joint. Delegate vote: agree, 78% (7/9); disagree, 11% (1/9); abstain, 11% (1/9). (Strong consensus) CONSENSUS STATEMENT TWO: When titrating the amount of correction of abduction deformity intraoperatively, the presence of adduction at the talonavicular joint on simulated weightbearing fluoroscopic imaging is an important sign of hypercorrection and higher risk for lateral column overload. Delegate vote: agree, 100% (9/9); disagree, 0%; abstain, 0%. (Unanimous, strongest consensus) CONSENSUS STATEMENT THREE: The typical range for performing a lateral column lengthening is between 5 and 10 mm to achieve an adequate amount of talonavicular coverage. Delegate vote: agree, 100% (9/9); disagree, 0%; abstain, 0%. (Unanimous, strongest consensus)

Lateral Column Lengthening

Category: Midfoot/Forefoot Introduction/Purpose: Lateral column lengthening (LCL) is a surgical procedure used to manage forefoot abduction occurring in patients with stage IIB Adult Acquired Flat Foot Deformity (AAFD). This procedure utilizes an opening wedge osteotomy of the calcaneus which is then filled with autograft, allograft, or a titanium wedge. The primary aim of this study was to compare the radiographic outcomes of these different bone substitutes in the setting of stage IIB AAFD with the use of LCL. Methods: All patients who underwent LCL from October 2008 until October 2018 were retrospectively reviewed. Preoperative weight bearing radiographs, initial postoperative radiographs and 1-year weight bearing radiographs were reviewed. The following radiographic measurements were recorded: talonavicular uncoverage angle, incongruency angle, and calcaneal pitch. Results: A total of 44 patients were included in our study. The mean age of the cohort was 54 (range 18-74). The study cohort was divided into two groups. There were 17 (38.7%) patients that received a titanium wedge and 27 (61.5%) that received autograft or allograft. Patients that underwent LCL with the autograft/allograft group were significantly older (p=0.006). Patients who underwent LCL with a titanium wedge had a significantly higher preoperative talonavicular angle (p=0.013). There were no significant differences in post-operative talonavicular uncoverage angle, incongruency angle or calcaneal pitch at 6 months or 1 year. Conclusion: Adult acquired flat foot deformity is a difficult disorder to treat surgically. Lateral column lengthening is a common surgical procedure used to treat forefoot abduction that occurs. Our results show that at 6 months and 1 year no radiographic difference exists between autograft/allograft bone substitutes versus titanium wedge in LCL. Future research should evaluate the differences in patient reported outcomes between autograft/allograft versus titanium wedge bone substitutes. [Table: see text]

Consensus Expert

Recommendation: There is evidence that the medial displacement calcaneal osteotomy (MDCO) can be effective in treating the progressive collapsing foot deformity (PCFD). This juxta-articular osteotomy of the tuberosity shifts the mechanical axis of the calcaneus from a more lateral position to a more medial position, which provides mechanical advantage in the reconstruction for this condition. This also shifts the action of the Achilles tendon medially, which minimizes the everting deforming effect and improves the inversion forces. When isolated hindfoot valgus exists with adequate talonavicular joint coverage (less than 35%-40% uncoverage) and a lack of significant forefoot supination, varus, or abduction, we recommend performing this osteotomy as an isolated bony procedure, with or without additional soft tissue procedures. The clinical goal of the hindfoot valgus correction is to achieve a clinically neutral heel, as defined by a vertical axis from the heel up the longitudinal axis of the Achilles tendon and distal aspect of the leg. The typical range when performing a MDCO, while considering the location and rotation of the osteotomy, is 7 to 15 mm of correction. Level of Evidence: Level V, consensus, expert opinion.

Background: The forefoot abduction component of the flexible adult-acquired flatfoot can be addressed with lengthening of the anterior process of the calcaneus. We hypothesized that the step-cut lengthening calcaneal osteotomy (SLCO) would decrease the incidence of nonunion, lead to improvement in clinical outcome scores, and have a faster time to healing compared with the traditional Evans osteotomy. Methods: We retrospectively reviewed 111 patients (143 total feet: 65 Evans, 78 SLCO) undergoing stage IIB reconstruction followed clinically for at least 2 years. Preoperative and postoperative radiographs were analyzed for the amount of deformity correction. Computed tomography (CT) was used to analyze osteotomy healing. The Foot and Ankle Outcome Scores (FAOS) and lateral pain surveys were used to assess clinical outcomes. Mann-Whitney U tests were used to assess nonnormally distributed data while χ2 and Fisher exact tests were used to analyze categorical variables (α = 0.05 significant). Results: The Evans group used a larger graft size ( P < .001) and returned more often for hardware removal ( P = .038) than the SLCO group. SLCO union occurred at a mean of 8.77 weeks ( P < .001), which was significantly lower compared with the Evans group ( P = .02). The SLCO group also had fewer nonunions ( P = .016). FAOS scores improved equivalently between the 2 groups. Lateral column pain, ability to exercise, and ambulation distance were similar between groups. Conclusion: Following SLCO, patients had faster healing times and fewer nonunions, similar outcomes scores, and equivalent correction of deformity. SLCO is a viable technique for lateral column lengthening. Level of Evidence: Level III, retrospective cohort study.

Talonavicular (TN) coalition is a rare pathological union of the talus and navicular bones. We report the case of a 7-year-old girl with a symptomatic TN coalition, who underwent operative management with a lateral column lengthening procedure using autologous iliac crest bone grafting. There are no complications to report and the graft was incorporated at an early stage. At 3 year follow-up the patient has remained pain-free since the operation and maintained alignment. To our knowledge, this is the first reported case of TN coalition treated with reconstructive surgery in a paediatric patient.

Background: The Cotton osteotomy, or dorsal-opening wedge osteotomy of the medial cuneiform (MC), is used to address medial column alignment to restore the static-triangle of support. There are many described techniques regarding the incision and osteotomy. Successful completion of the osteotomy requires knowledge of the anatomy, particularly the location of the medial dorsal cutaneous nerve (MDCN). This study describes the relationship between MDCN, tibialis anterior, extensor-hallucis-longus tendon, and ligamentous attachments to the MC. A technique to determine a safe location for the osteotomy is also described. Methods: Twelve fresh-frozen adult foot specimens were used for this study (7 male and 5 female). The MDCN and its branches were dissected and its relationship with the MC was documented. Osteotomy tilt angle and relationship to structures around the MC were measured. Results: MDCN traveled medially and distally over the dorsum of the MC, and a small branch to the MC was observed. The tilt angle was 80.1 ±1.4 degrees. There was no significant difference between the distance from the distal-articular surface to the midline of the cuneiform and to the interosseous ligament ( P = .69), or between the distance from the distal-articular surface to the second tarsometatarsal joint and to the origin of the Lisfranc ligament ( P = .12). Conclusions: The dorsal-medial-oblique incision effectively protected MDCN and the MC. We believe the osteotomy should be performed in the safe zone to maintain the stability of the opening wedge. Clinical relevance: The dorsal-medial-oblique incision could reduce the risk of injury to the MDCN and the tibialis-anterior tendon.

Interphalangeal hyperextension is one of the major hallux deformities in patients with rheumatoid arthritis; however, there is yet no established surgical method for this deformity. We here present the case of a 69-year-old female patient with rheumatoid arthritis who developed hallux interphalangeal hyperextension and painful callosity on the plantar hallux accompanied by limited dorsiflexion at the metatarsophalangeal joint. Lateral weight-bearing radiograph of the foot revealed misalignment of the medial column and hallux, including a collapsed medial arch, elevated first metatarsal, plantar flexion and deviation of the proximal phalanx, and hyperextension of the distal phalanx. The foot was successfully treated and became symptom-free with opening wedge osteotomy of the medial cuneiform, plantar and proximal translation of the metatarsal head, and tenotomy of the extensor hallucis longus. This case suggests that reconstruction of the sagittal alignment of the medial column and hallux through a combination of osteotomy and soft tissue intervention could be an optional treatment for interphalangeal hyperextension.

Purpose: To determine the effect of the additional first ray osteotomy on hindfoot alignment for the correction of pes plano-valgus. Methods: Data obtained from 37 consecutive patients recruited from 2006 to 2014 who underwent medial displacement calcaneal osteotomy (MDCO) alone (group H) or MDCO followed by medial cuneiform opening wedge osteotomy (MCOWO) (group HF) with a minimum 1-year follow-up were reviewed retrospectively. The mean follow-up periods were 34 and 32 months. Results: Degree of decrease of Talonavicular coverage angle (TNCA) via surgery or postoperative TNCA on standing foot AP radiographs were not significantly different between group H and HF ( p = 0.287). The calcaneal pitch angle and medial cuneiform height on the standing foot lateral radiographs was significantly increased after operation in group HF ( p = 0.01), there was a significant difference with group H as well ( p = 0.033). In group HF, the Meary’s angle was significantly decreased after operation, a significant difference compared to group H ( p = 0.009). Hindfoot alignment angle on the hindfoot alignment view was decreased after operation in both groups but was not significantly different between both groups ( p = 0.410). Hindfoot alignment ratio was also increased after the operation in both groups, but was not different between two groups ( p = 0.783). Conclusion: The additional first ray osteotomy using MCOWO had no correctional power for hindfoot correction, although it caused improvement in some radiographic parameters.
