SummaryObjectives: Femoral osteotomies are frequently completed to correct malalignment associated with patellar luxation. The objectives of this study were to compare the use of: 1) two different types of jig; and 2) different types of osteotomy in the realignment of canine femoral bone models which possessed various iterations of angular deformity.Methods: Models of canine femora possessing distal varus, external torsion and a combination of varus and torsion underwent correction utilizing two alignment jigs (Slocum jig and Deformity Reduction Device) and either a closing wedge ostectomy (CWO) or an opening wedge osteotomy (OWO). Post-correctional alignment was evaluated by radiographic assessment and compared between groups.Results: The use of the Slocum jig resulted in frontal plane overcorrection when used with CWO in models of femoral varus, and when used with OWO in models of femoral varus and external torsion when compared to other techniques. The Deformity Reduction Device tended to realign the frontal plane closer to the post-correction target value in all angulation types. The use of both jigs resulted in undercorrection in the transverse plane in models with varus and torsion.Clinical significance: Jig selection and osteotomy type may lead to different post-correctional alignment results when performing distal femoral osteotomies. Whereas OWO allows accurate correction when used with either jig to address frontal plane deformities, the Deformity Reduction Device can be utilized with both CWO and OWO to correct torsion-angulation femoral deformities to optimize frontal plane alignment.

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.

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.

Forefoot Varus

Adult flatfoot is a common pathology characterized by multiplanar deformity involving hindfoot, midfoot, and forefoot. Various surgical techniques have been described for the treatment but may not adequately correct the fixed forefoot varus component. Residual forefoot supination can be addressed by a plantar flexing opening wedge osteotomy of the medial cuneiform, also known as a Cotton osteotomy. Thus, the aims of this study were to compare clinical, radiological, and functional outcome after Cotton osteotomy, in patients treated with bone allograft or metallic implant. Consequently, 36 patients treated with opening wedge osteotomy of the medial cuneiform for forefoot varus were studied retrospectively. Patients were divided into two groups: the bone allograft group (HBG) (n=18) and the metallic implant group with BIOFOAM® Cotton Wedges (TTW) (n=18). Radiographic assessment and clinical scores including American Orthopaedic Foot and Ankle Society score, Foot Function Index, and visual analogue scale for pain were collected before operation and the last follow-up. The difference between baseline and follow-up for both groups was statistically significant for all the clinical scores and radiographic angles (p < 0.05). Most participants (92%) were very satisfied after surgery. Our results showed that Cotton osteotomy with a metallic implant provided both good clinical and radiographic outcomes comparable with bone allograft.

Background: While proximal first metatarsal osteotomy combined with distal soft tissue realignment is accepted as standard treatment of moderate to severe hallux valgus with metatarsus primus varus, none of the described proximal metatarsal osteotomies address the hyper-obliquity of the first metatarsocuneiform joint. An opening-wedge osteotomy of the medial cuneiform can potentially correct the 1-2 intermetatarsal angle (IMA) in addition to normalizing the hyper-obliquity of the first tarsometatarsal (TMT) joint. The purpose of this study was to retrospectively review the early radiographic and clinical results of the use of a medial cuneiform opening-wedge osteotomy fixed with a low-profile wedge plate combined with distal soft tissue realignment for the treatment of hallux valgus. Methods: Fourteen feet (13 patients; 2 male and 11 female, average age 56 years, range 22-75) with hallux valgus underwent an opening-wedge osteotomy of the medial cuneiform fixed with a low-profile nonlocking wedge plate combined with distal soft tissue realignment. The mean preoperative hallux valgus angle (HVA) was 32 degrees and the IMA was 16 degrees. HVA, 1-2 IMA, proximal first metatarsal inclination (PFMI), and presence of osteoarthritis of the first TMT joint were assessed on preoperative and final postoperative radiographs. Final postoperative radiographs were also evaluated for radiographic union and hardware failure at an average of 7 months (range, 3-19 months) postoperatively. Results: A mean intraoperative correction of 19 degrees and 7 degrees was achieved for the HVA and IMA, respectively. The mean HVA was 22 degrees and the mean IMA was 11 degrees at the time of final follow-up. At final follow-up, a recurrence of the deformity was observed in 12/14 feet. There were 2 nonunions—one plate failure and one screw failure. No first TMT joint instability or arthritis was observed. All patients were ambulatory without assistive device in either fashionable or comfortable shoe wear. Conclusion: Medial cuneiform opening-wedge osteotomy resulted in unreliable correction of HVA and IMA at short-term follow-up with a high rate of early recurrence of hallux valgus deformity and a complication rate similar to that of the Lapidus procedure. This procedure cannot be recommended for addressing hallux valgus in the setting of increased obliquity of the first TMT joint. Level of Evidence: Level IV, case series.

Forefoot Varus

Category: Hindfoot, Midfoot/Forefoot, Flatfoot Introduction/Purpose: Forefoot varus is a common component of flatfoot deformity that is often surgically addressed. There are multiple options to plantarflex the medial column of the foot, with midfoot fusion and the Cotton osteotomy being the most common. This study analyzes radiographic outcomes and complications when a titanium wedge is used for structural support in a dorsal opening wedge Cotton osteotomy of the medial cuneiform. Methods: Between December 2016 and May 2018, 32 feet in 31 patients were treated with medial column titanium wedges for residual forefoot varus in association with flatfoot corrections. All participants had preoperative and weight-bearing postoperative radiographs examined for analysis of radiographic correction. The average age of the patients was 41.1 years (Range: 12-70). The average follow-up time for patients was 8.1 months (6-17 months). All patients underwent a six-month non-operative treatment course prior to operative intervention. The average time from the initial visit with the primary surgeon (JFD, ARK) to the day of surgical intervention was 211 days (29-1296 days). The choice to use a titanium wedge, versus an alternative method of correction of the medial column, was at the discretion of the primary surgeon (JFD, ARK). Results: A dorsal opening wedge medial cuneiform osteotomy was performed in all patients. All radiographic parameters showed statistically significant correction from preoperative to postoperative. All cases had multiple concomitant procedures performed to address the flatfoot deformity, so it is difficult to isolate the effect of the medial cuneiform osteotomy. 30/31 cases went on to successful union of the osteotomy within the study follow-up period. There were no instances of hardware pain requiring implant removal. There was 1 case of plantar gapping at the osteotomy site and implant loosening that required revision to a larger titanium wedge which healed uneventfully. No implants had supplemental fixation or additional bone graft placement at the osteotomy site. Conclusion: To our knowledge, this represents the first reported series on the use of structural titanium wedges with an opening wedge osteotomy of the medial cuneiform. There is limited data regarding the use of metal wedges for flatfoot correction. Nearly every patient in our series underwent concomitant procedures as part of the flatfoot reconstruction. This makes it difficult to isolate the effect of the deformity correction provided solely by the medial column correction. Our study suggests that metal wedges are both safe and effective for use in medial column correction, and future studies comparing titanium wedges to traditional techniques are needed.
