Background: Shortening and dorsiflexion of the first metatarsal are known potential side effects of metatarsal osteotomies for hallux valgus (HV) with the potential to cause transfer metatarsalgia. We compared the effect of the first tarsometatarsal joint arthrodesis (Lapidus procedure), proximal lateral closing wedge osteotomy (PLCWO), and intermetatarsal suture button fixation procedures on the length and dorsiflexion of the first ray. Methods: We retrospectively evaluated 105 feet in 99 patients with 30 weeks of follow-up. The average age was 54 years. Seventy-four feet had a Lapidus procedure, 12 had a PLCWO, and 19 had intermetatarsal suture button fixation. Digital radiographic measurements were made for the pre- and postoperative hallux valgus angle (HVA) and intermetatarsal angle (IMA), absolute and relative shortening of the first ray, and dorsiflexion. Results: Preoperative HVA and IMA did not differ between treatment groups ( P > .05 for each). Similar corrections of HVA (30.5-13.5 degrees) were achieved between all groups ( P > .05). The IMA was improved more in the Lapidus group (14.3-6.5 degrees) compared with the suture button fixation group (14.2-8.1 degrees) ( P = .045). There were significant differences in the change in absolute first cuneiform–metatarsal length (FCML) between the Lapidus (–1.6 mm), PLCWO (–2.3 mm), and intermetatarsal suture button fixation (+1.9 mm) procedure ( P = .004). There were also significant differences in relative first metatarsal shortening between the Lapidus (0.1 mm relative shortening), PLCWO (1.1 mm relative shortening), and intermetatarsal suture button fixation (1.3 mm lengthening) procedure ( P < .001). The average dorsiflexion differed between the Lapidus (1.8 degrees) and suture button fixation (0.4 degrees) groups ( P = .004). Conclusion: Intermetatarsal suture button fixation relatively lengthened the first ray, the Lapidus procedure maintained length, and the PLCWO relatively and absolutely shortened it. Dorsiflexion may be higher with the Lapidus and osteotomy procedures. Level of Evidence: Level III, retrospective comparative series.

Category: Bunion; Lesser Toes; Midfoot/Forefoot Introduction/Purpose: Shortening and dorsiflexion of the first metatarsal are a known side effect of metatarsal osteotomies for hallux valgus (HV) deformity with the potential to cause transfer metatarsalgia. We compared the effect of the first tarsometatarsal joint arthrodesis (Lapidus), proximal lateral closing wedge osteotomy (PLCWO), and intermetatarsal suture button fixation procedures on the length and dorsiflexion of the first ray. Methods: We retrospectively evaluated 123 feet in 115 patients. The average age was 54. There were 106 females. Eighty-four feet had a Lapidus procedure, 14 had a PLCWO, and 24 had intermetatarsal suture button fixation. Digital radiographic measurements were made for pre- and postoperative hallux valgus angle (HVA) and intermetatarsal angle (IMA), absolute and relative shortening of the first ray, and dorsiflexion. Results: Preoperative HVA and IMA did not differ between treatment groups (p>0.05 for each). Similar corrections of HVA (30.1 to 12.3 degrees) and IMA (14.7 to 7.0 degrees) were achieved in all three groups (p>0.05). There were significant differences in absolute first-cuneiform-metatarsal length (FCML) between Lapidus (-1.5mm), PLCWO (-2.5mm), and intermetatarsal suture button fixation (+1.1mm) (p<0.05). There were also significant differences in relative 1st metatarsal shortening between Lapidus (0.32mm relative lengthening), PLCWO (1.05mm relative shortening), and intermetatarsal suture button fixation (1.24mm lengthening) (p<0.05). Average dorsiflexion differed between the Lapidus (1.95 degrees) and PLCWO groups (0.49 degrees) (p<0.05). Conclusion: The use of the intermetatarsal suture button fixation relatively lengthens the first ray, whereas the Lapidus and PLCWO shorten it. Dorsiflexion may be higher with Lapidus and osteotomy procedures. These findings may be helpful to explain postoperative symptoms of metatarsalgia and for the surgeon’s selection of the appropriate surgical technique for preoperative planning. [Table: see text]

Some authors reported the results from percutaneous distal metatarsal osteotomy for hallux valgus recently. On the other hand, there are few reports of percutaneous proximal metatarsal osteotomy. The purpose of the present study was to evaluate the radiographic results of percutaneous proximal closing wedge osteotomy with Akin osteotomy for correction of severe hallux valgus and increasing longitudinal arch height. Consecutive 17 feet (mean age = 70.8 years) were investigated. The mean follow-up was 22 months. Excision of medial eminence, distal soft tissue release, and Akin osteotomy were all performed percutaneously and concurrently. Weight-bearing anteroposterior and lateral radiographs of the feet were acquired preoperatively and at final follow-up. On the anteroposterior radiographs, hallux valgus angle, intermetatarsal angle, and first metatarsal shortening were measured. On the lateral radiographs, talometatarsal angle, calcaneal pitch angle, and first metatarsal dorsiflexion were measured. The average improvements in hallux valgus angle and intermetatarsal angle were 27.6° and 9.9°, respectively. The average first metatarsal shortening was 2.7 mm. The first metatarsal dorsiflexion improved by 2.2°; however, other parameters did not improve significantly. In conclusion, percutaneous proximal closing wedge osteotomy with Akin osteotomy corrects severe hallux valgus; however, the procedure does not increase the medial longitudinal arch.

Background: Although percutaneous surgery for the treatment of hallux valgus is popular in Europe, there is sparse English written literature documenting its efficacy. This study described the operative techniques using percutaneous basal closing wedge osteotomy of the first metatarsal in correction of moderate to severe hallux valgus (HV) and its short-term clinical outcomes. We postulated that satisfactory correction of hallux valgus (HV) angle, intermetatarsal (IM) angle, and patients’ clinical outcomes could be achieved with this technique. Methods: We conducted a retrospective review of 25 feet in 23 patients who underwent a percutaneous basal closing wedge osteotomy of the first metatarsal (MT1) combined with a mini-open modified McBride procedure and mini-open resection of medial eminence. Follow-up averaged 21.5 months. Radiographic outcomes included pre- and postoperative HV angle, IM angle, absolute and relative shortening of MT1, and time to union. American Orthopaedic Foot & Ankle Society (AOFAS) scores were compared between pre- and postoperatively. Results: The average HV angle improved from 39.4 (range, 29-58.3) degrees preoperatively to 14.7 (range, 0.1-23.2) degrees postoperatively ( P < .05). IM angle improved from 14.9 (range, 6.7-22.4) degrees to 6.6 (range, 0.9-14.8) degrees ( P < .05). The average absolute shortening was 3.8 (range, 0.27-12.91) mm and the relative shortening was 0.8 (range, 0.05-1.91) mm. There was no delayed union or malunion at the osteotomy site. The average AOFAS score improved from 39 (range, 12-50) to 81 (range, 70-93) ( P < .05). Conclusions: Satisfactory hallux valgus deformity correction and patients’ outcomes were achieved with this technique. Our results are similar to results reported in other studies using open techniques. There was no malunion or delayed union of the osteotomy. Level of Evidence: Level IV, case series study.

After 2 to 4 years, 25 patients (27 feet) who had a proximal closing wedge osteotomy of the first metatarsal and an adductor tenotomy were reviewed. A total of 20 patients (22 of 27 feet) were completely satisfied; 5 patients not completely satisfied had metatarsalgia because of dorsal displacement of the first metatarsal head. Radiographic measurements showed a narrowing of the forefoot rather than a large change in the intermetatarsal angle. The recovery period was long, an average of 11 weeks. Pin inflammation occurred in 5 patients and incisional neuromas in 2 patients. The risk of these complications must be taken into consideration when using this operation.

Background:Hallux valgus is a multiplanar deformity of the first ray. Traditional correction methods prioritize the transverse plane, a potential factor resulting in high recurrence rates. Triplanar first tarsometatarsal (TMT) arthrodesis uses a multiplanar approach to correct hallux valgus in all 3 anatomical planes at the apex of the deformity. The purpose of this study was to investigate early radiographic outcomes and complications of triplanar first TMT arthrodesis with early weightbearing.Methods:Radiographs and charts were retrospectively reviewed for 57 patients (62 feet) aged 39.7 ± 18.9 years undergoing triplanar first TMT arthrodesis at 4 institutions between 2015 and 2017. Patients were allowed early full weightbearing in a boot walker. Postoperative radiographs were compared with preoperative radiographs for hallux valgus angle (HVA), intermetatarsal angle (IMA), tibial sesamoid position (TSP), and lateral round sign. Any complications were recorded.Results:Radiographic results demonstrated significant improvements in IMA (13.6 ± 2.7 degrees to 6.6 ± 1.9 degrees), HVA (24.2 ± 9.3 degrees to 9.7 ± 5.1 degrees), and TSP (5.0 ± 1.3 to 1.9 ± 0.9) from preoperative to final follow-up ( P < .001). Lateral round sign was present in 2 of 62 feet (3.2%) at final follow-up compared with 52 of 62 feet (83.9%) preoperatively. At final follow-up, recurrence was 3.2% (2/62 feet), and the symptomatic nonunion rate was 1.6% (1/62 feet). Two patients required hardware removal, and 2 patients required additional Akin osteotomy.Conclusion:Early radiographic outcomes of triplanar first TMT arthrodesis with early weightbearing were promising with low recurrence rates and maintenance of correction.Level of Evidence:Level IV, retrospective case series.

Akin Osteotomy

Category: Bunion Introduction/Purpose: In hallux valgus deformity less weight can be borne by the first ray which may lead to transfer metatarsalgia and lesser toe deformities. Depending on the exact configuration of the bone cuts during the scarf procedure, an iatrogenic shortening of the first metatarsal may occur which may diminish weightbearing ability of the first ray as well, causing transfer metatarsalgia. The aim of the present study was therefore to determine preoperative and postoperative changes in length of the first metatarsal by using different methods of measuring metatarsal length. Methods: A consecutive series of 118 feet in 106 patients (89% female, 11% male) was enrolled, who underwent correctional osteotomy (Scarf-with/without Akin-Osteotomy) from May 2015 to July 2017 at a single institution. Patients, who underwent additional shortening osteotomy of the metatarsals, were excluded. Average age at the time of surgery was 51 years (range, 14 to 83 years). Pre- and postoperative angle measurement of hallux valgus- and intermetatarsal angle was assessed at between six weeks and three months postoperatively on standardized weight-bearing radiographs in dorsoplantar plane. We also identified early complications in hallux valgus surgery. An assessment and comparison of different methods of measuring metatarsal length (length of first metatarsal, ratio first to second metatarsal, Coughlin method) postoperatively was performed to identify the amount of shortening with this technique. Results: Hallux valgus angle was statistically significant reduced by an average of 18.6° (28.3° preoperatively to 9.7° postoperatively, p < 0.001), intermetatarsal angle by 7.7° (12.8° to 5.1°, p < 0.001). Measuring the length of the first metatarsal, in all three methods a statistically significant reduction of the first metatarsal length could be detected. Mean absolute shortening of 1.8 mm was measured (p < 0.001). The ratio of the first metatarsal to the second metatarsal averaged -0.03 (p = 0.02). The mean relative lengthening of the second metatarsal, using the method described by Coughlin, was 0.42 mm (from 4.51 to 4.89 mm, p < 0.001) on average. Of those three methods, the Coughlin method showed the highest correlation. 6 minor complications were observed (5%). Conclusion: In the current study we could demonstrate a significant reduction of hallux valgus angle and intermetatarsal angle with hallux valgus correction using Scarf-/Akin-Osteotomy, with a low complication rate. However, statistically significant shortening of the first metatarsal could be detected as well. Further research is required to improve and establish a hallux valgus correction technique without shortening of the first metatarsal.

Background: Hallux valgus recurrence is an unsatisfactory complication, with many causes postulated. This study investigated the effect of pes planus on recurrence after scarf osteotomy. Methods: A total of 183 feet were retrospectively reviewed. All patients were treated with a scarf osteotomy and if required Akin osteotomy. We measured preoperative lateral talus first metatarsal angle (T1MA) to study pes planus; an angle of under −4 degrees was considered pes planus. We measured pre and postoperative hallux valgus angle (HVA), intermetatarsal angle (IMA), and sesamoid location. In total 164 feet were suitable for inclusion, with follow-up of at least 6 months (10 males and 154 females, mean age: 52 years). Results: Recurrence frequency (HVA greater than 15 degrees) was 27 feet (16%). Hallux valgus recurrence was not influenced by gender ( P value = .66) or preoperative IMA ( P value = .48). Preoperative HVA greater than 35 degrees was associated with increased frequency of recurrence ( P value = .004). Those with T1MA less than −10 degrees demonstrated progression in HVA and deterioration in sesamoid location up to 6 months postoperatively ( P value = .038). HVA did not progress beyond 6 months. The prevalence of recurrent hallux valgus with normal T1MA was 1%, in T1MA −4 to −10 degrees it was 29% and in T1MA less than −10 degrees it was 47% ( P value <.001). Breaks in T1MA less than −4 degrees were found at the naviculocuneiform joint in 68% of feet in this series. Conclusion: The prevalence of hallux valgus recurrence correlated with the severity of pes planus. Level of Evidence: Level III, retrospective cohort study.

Background: Bipartite hallucal sesamoids are often found in patients with hallux valgus. However, it is unknown whether bipartite hallucal sesamoids affect the results of hallux valgus surgery or not. The purpose of the present study was to evaluate the outcomes of chevron osteotomy for hallux valgus with and without bipartite hallucal sesamoid. Methods: A total of 152 patients (168 feet) treated with distal or proximal chevron osteotomy for hallux valgus constituted the study cohort. The 168 feet were divided into 2 groups: bipartite hallucal sesamoid (31 feet) and without bipartite hallucal sesamoid (137 feet). Hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), tibial sesamoid position, and first metatarsal length were measured for radiographic outcomes and the American Orthopaedic Foot & Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal (MTP-IP) score was measured for clinical outcomes. Results: All radiographic measurements and the AOFAS score showed significant ( P < .05) improvement at the time of final follow-up compared with preoperative measurements in both groups. No significant differences ( P > .05) were found between the 2 groups in terms of HVA, IMA, DMAA, tibial sesamoid position, metatarsal shortening, and AOFAS score on final follow-up. Conclusions: This study suggests that bipartite hallucal sesamoids do not affect the results of hallux valgus surgery. Level of Evidence: Level III, retrospective comparative study.

Background: Hallux valgus (HV) is a triplanar deformity of the first ray including pronation of the first metatarsal with subluxation of the sesamoids. The purpose of this study was to investigate if a first tarsometatarsal fusion (modified Lapidus technique), without preoperative knowledge of pronation measured on weightbearing computed tomographic (CT) scans, changed pronation of the first metatarsal and determine if reduction of the sesamoids was correlated with changes in first metatarsal pronation. Methods: Thirty-one feet in 31 patients with HV who underwent a modified Lapidus procedure had preoperative and at least 5-month postoperative weightbearing CT scans and radiographs. Differences in preoperative and postoperative pronation of the first metatarsal using a 3-dimensional computer-aided design, HV angle, and intermetatarsal angle (IMA) were calculated using Wilcoxon signed-rank tests. After dividing patients into groups based on sesamoid station, Kruskal-Wallis H tests were used to compare first metatarsal pronation between the groups. Results: The mean preoperative and postoperative pronation of the first metatarsal was 29.0 degrees (range 15.8-51.1, SD 8.7) and 20.2 degrees (range 10.4-32.6, SD 5.4), respectively, which was a mean change in pronation of the first ray of −8.8 degrees ( P < .001). There was no difference in pronation of the first ray when stratified by postoperative sesamoid position ( P > .250). The average preoperative and postoperative IMA was 16.7 degrees (SD 3.2) and 8.8 degrees (SD 2.8), which demonstrated a significant change ( P < .001). Conclusions: The modified Lapidus procedure was an effective tool to change pronation of the first ray. Reduction of the sesamoids was not associated with postoperative first metatarsal pronation. Level of Evidence: Level IV, case series.
