Category: Midfoot/Forefoot Introduction/Purpose: Total joint replacement (TJR) and arthrodesis (A) are treatment options for severe osteoarthritis of the first metatarsophalangeal joint (MTP1). The aim of this study was to compare outcome (clinical and pedographic) of TJR (Roto- Glide) and A of MTP1. Methods: All patients that completed follow-up of at least 24 months after TJR and A of MTP1 before November 5, 2018 were included in the study. Preoperatively and at follow-up, radiographs and/or weight-bearing computed tomographies (WBCT) were obtained. Degenerative changes were classified in four degrees. Standard dynamic pedography was performed (percentage force at first metatarsal head/first toe from force of entire foot). Visual-Analogue-Scale Foot and Ankle (VAS FA) and MTP1 range of motion for dorsi-/plantarflexion (ROM) were registered and compared pre-operatively and follow-up. From November 24, 2011 until October 31, 2016, 25 TJR and 49 A were performed that completed follow-up. Results: Parameters (average values if not stated otherwise) for TJR/A were preoperatively: age 59/60 years; 7(28%)/14(29%) male; height 168/169 cm; weight 71/72 kg; degree degenerative changes 3.3/3.1; ROM 19.4/0/9.8°//20.3/0/9.2°; percentage force first metatarsal/first toe 7.9/14.6//8.5/15.3; VAS FA 45.9/46.2. Six wound healing delays were registered (TJR 2, A 4) as only complications. Follow-up time on average 45.7/46.2 and range 25.0-80.3/24.1-81.1 months. VAS FA at follow-up was 73.4/70.2.; percentage force first metatarsal/first toe 15.8/5.8//12.3/10.8; ROM 35.6/0/10.5°//10.5/0/0. Parameters did not differ between TJR and A (each p>.05) except higher force percentage first toe and lower ROM for A at follow-up (each p<.05). VAS FA and pedography parameters improved for TJR and A between preoperatively and follow-up, ROM increased for TJR and decreased for A (each p<.05). Conclusion: TJR and A were performed in similar patient cohorts regarding demographic parameter, degree of degenerative changes, ROM, pathological pedographic pattern, and VAS FA. TJR and A improved pathological pedographic pattern and VAS FA at minimum follow-up of 24 months. TJR additionally improved ROM and showed better pedographic pattern (and not different to physiological pattern) than A. Survival rate of TJR was 100% up to 6 years. In this study, TJR was a valuable alternative to A for treatment of severe MTP1 osteoarthritis.

Category: Midfoot/Forefoot Introduction/Purpose: Total joint replacement (TJR) and arthrodesis (A) are treatment options for severe osteoarthritis of the 1st metatarsophalangeal joint (MTP1). The aim of this study was to compare outcome (clinical and pedographic) of JTR (Roto-Glide, Implants International, Thornaby-On-Tees, UK) and A of MTP1. Methods: All patients that completed follow-up of at least 24 months after TJR and A of MTP1 before November 5, 2017 were included in the study. The data was extracted from a prospectively acquired database starting November 1, 2011 including all operatively treated patient at the authors´ institution. Exclusion criteria were bilateral treatment (n=24), additional procedures at other toes (n=34), A for revision of TJR (n=12), TJR exchange (n=5), and not completed minimum-24-month-follow-up (n=20). Preoperatively and at follow-up, radiographs and/or weight-bearing computed tomographies were obtained. Degenerative changes were classified in four degrees. Standard dynamic pedography was performed (percentage force at 1st metatarsal/1st toe from force of entire foot). Visual-Analogue-Scale Foot and Ankle (VAS FA) and MTP1 range of motion for dorsi-/plantarflexion (ROM) were registered. All parameters were compared between TJR and A and between preoperatively and follow-up. Results: From November 24, 2011 until October 31, 2015, 19 TJR and 38 A were performed. Parameters (average values if not stated otherwise) for TJR/A were preoperatively: mean age 59/60 years; 5(26%)/10(26%) male; height 167/166 cm; weight 73/74 kg; degree degenerative changes 3.3/3.1; ROM 10.3/0/18.8°//10.8/0/19.2°; percentage force 1st metatarsal/1st toe 7.8/14.5//8.4/15.2; VAS FA 45.5/44.9. Follow-up time on average 37.4/32.6 and range 25.3-71.3/24.1-67.1 months. VAS FA at follow-up was 71.7/69.4; percentage force 1st metatarsal/1st toe 15.6/5.5//16.5/10.5; ROM 35.4/0/20.5°//10.2/0/0. Parameters did not differ between TJR and A (each p>.05) except higher force percentage 1st toe and lower ROM for A at follow-up (each p<.05). VAS FA and pedography parameters improved for TJR and A between preoperatively and follow-up, ROM increased for TJR and decreased for A (each p<.05). Conclusion: TJR and A were performed in similar patient cohorts regarding demographic parameter, degree of degenerative changes, ROM, pathological pedographic pattern, and validated clinical scores (VAS FA). Both improved pathological pedographic pattern and VAS FA at minimum follow-up of 24 months. TJR additionally improved ROM and showed better pedographic pattern (and not different to physiological pattern) than A. TJR was similar to A except better ROM and better pedographic pattern. Survival rate of TJR was 100% up to 6 years. In this study, TJR was a valuable alternative to A for treatment of severe MTP1 osteoarthritis.

Category: Ankle Arthritis Introduction/Purpose: Total joint replacement (TJR) and arthrodesis (A) are treatment options for severe osteoarthritis of the ankle. The aim of this study was to compare outcome (clinical and pedographic) of JTR (STAR, Stryker, Airview Boulevard, MN, USA) and A of the ankle. Methods: All patients that completed follow-up of at least 24 months after TJR and A of the ankle before November 5, 2017 were included in the study. The data was extracted from a prospectively acquired database starting November 1, 2011 including all operatively treated patient at the authors´ institution. Exclusion criteria were bilateral treatment (n=14), extensive additional procedures such as arthrodesis at other joints (n=54), A for revision of TJR (n=8), TJR exchange (n=10), and not completed minimum-24-month-follow-up (n=26). Preoperatively and at follow-up, radiographs and/or weight-bearing computed tomographies were obtained. Degenerative changes were classified in four degrees. Standard dynamic pedography was performed (percentage force at hindfoot and forefoot from force of entire foot). Visual-Analogue-Scale Foot and Ankle (VAS FA) and ankle range of motion for dorsi-/plantarflexion (ROM) were registered. All parameters were compared between TJR and A and between preoperatively and follow-up. Results: From October 11, 2011 until October 31, 2015, 36 TJR and 28 A were performed. Parameters (average values if not stated otherwise) for TJR/A were preoperatively age 61/52 years; 20(56%)/14(50%) male; height 171/175 cm; weight 83/87 kg; degree degenerative changes 3.5/3.6; ROM 5.6/0/22.8°//4.8/0/22.1°; percentage force hindfoot/forefoot 45.5/38.3//48.4/34.5; VAS FA 43.8/40.3. Follow-up time on average 35.8/33.1 and range 25.4-66.4/24.1-71.3 months. VAS FA at follow-up was 68.6/61.3; percentage force hindfoot/forefoot 64.3/22.3//53.5/28.5; ROM 15.4/0/33.6°//0/0/0. Parameters did not differ between TJR and A (each p>.05) except lower age for A, higher VAS FA, hindfoot force percentage and ROM for TJR at follow-up (each p<.05). VAS FA and pedography parameters improved for TJR and A between preoperatively and follow-up, ROM increased for TJR and decreased for A (each p<.05). Conclusion: TJR and A were performed in similar patient cohorts regarding demographic parameter (except lower age for A), degree of degenerative changes, ROM, pathological pedographic pattern, and validated clinical scores (VAS FA). Both improved pathological pedographic pattern and VAS FA at minimum follow-up of 24 months. TJR additionally improved ROM and showed better pedographic pattern (and not different than physiological pattern) and VAS FA than A. TJR resulted in better clinical outcome including ROM and pedographic pattern. Survival rate of TJR was 100% up to 5.5 years. In this study, TJR outperformed A for treatment of severe ankle osteoarthritis.

Fungal Osteomyelitis

Most fungal infections primarily occur in immunocompromised patients. We describe a case of osteomyelitis involving the first metatarsal head due to Cryptococcus neoformans in a previously healthy immunocompetent patient. She was treated with surgical debridement combined with antifungal drug therapy for 6 months. At 5-year follow-up, she remained symptom free with full range of motion of the first metatarsophalangeal joint. Fungal osteomyelitis should be considered as a possible cause in osteolytic lesions in the metatarsal bone.

The effects of the Youngswick osteotomy on plantar peak pressure distribution in the forefoot are presented for 17 patients (23 feet) with mild-to-moderate hallux limitus deformity and 23 control subjects (23 feet). During 2 years of follow-up, the operation produced a significant increase in the range of dorsiflexion of the first metatarsophalangeal joint in these patients, reaching near-normal values. Preoperative and postoperative measurements, using a pressure-distribution measurement system, show that peak pressure beneath the hallux and the first metatarsal head remained unchanged. However, peak pressure was significantly increased beneath the second metatarsal head and decreased beneath the fifth metatarsal head. These findings suggest that the foot functioned in a less inverted manner postoperatively. Compared with normal feet, hallux limitus feet demonstrated significantly higher peak pressure beneath the fourth metatarsal head preoperatively and postoperatively.

The authors present a review of the literature concerning the pathogenesis, diagnosis, and treatment of osteochondral defects of the lower extremity. A case of bilateral osteochondritis dissecans of the first metatarsophalangeal joint in a 43-year-old female is presented, including surgical treatment with 1- and 3-year follow-up examinations. The correlation between articular damage to the first metatarsal head and concomitant hallux limitus and hallux rigidus is discussed. The authors also propose that osteochondritis dissecans lesions almost always occur on the convex surface of a joint because of a convergence of impaction forces.

Valgus Angle

The Austin osteotomy is a widely accepted method for correction of mild and moderate hallux valgus. In view of publications by Kitaoka et al. in 1991 and by Mann and colleagues, a more radical lateral soft tissue procedure was added to the originally described procedure. From September 1992 to January 1994, 85 patients underwent an Austin osteotomy combined with a lateral soft tissue procedure to correct their hallux valgus deformities. Seventy-nine patients (94 feet) were available for follow-up. The average patient age at the time of the operation was 47.1 years, and the average follow-up was 16.2 months. The average preoperative intermetatarsal angle was 13.9°, and the average hallux valgus angle was 29.7°. After surgery, the feet were corrected to an average intermetatarsal angle of 5.8° and an average hallux valgus angle of 11.9°. Sesamoid position was corrected from 2.1 before surgery to 0.5 after surgery. The results were also graded according to the Hallux Metatarsophalangeal Interphalangeal Score, and the functional and cosmetic outcomes were graded by the patient. Dissection of the plantar transverse ligament and release of the lateral capsule repositioned the tibial sesamoid and restored the biomechanics around the first metatarsophalangeal joint. There was no increased incidence of avascular necrosis of the first metatarsal head compared with the original technique.

Category: Midfoot/Forefoot Introduction/Purpose: Although the first metatarsophalangeal joint sesamoids have biomechanical value in the foot, pathologic conditions of these sesamoids are a source of disabling pain for patients, particularly during toe-off. Underlying causes include acute fracture, acute separation of bipartite sesamoids, sesamoiditis caused by repetitive trauma, infection, chondromalacia, osteochondritis dissecans, and osteoarthritis. Nonoperative treatment is the initial standard of care and has satisfactory outcomes overall, but operative management may be indicated in cases of pain refractory to conservative management. Surgical management includes tendo-Achilles or gastrocnemius lengthening, dorsiflexion osteotomy at the base of first metatarsal, corrective osteotomies, fusions for fixed pes cavus foot. Sesamoidectomy is a relatively uncommon procedure but should be considered if 6- 12 months of conservative managements fail or if the patient experiences ongoing debilitating symptoms. Methods: A retrospective chart review was conducted at our institution from 2009-2018. Twelve patients diagnosed with fibular sesamoiditis were treated with sesamoidectomy. Baseline patient demographics as well as postoperative outcomes were recorded. All patients were initially treated for an extended period conservatively with orthotics, anti-inflammatory medications, physical therapy, limitation of activity and a trial of non-weight bearing. Despite these measures, symptoms persisted for these twelve patients - all of who then underwent fibular sesamoidectomy for their symptoms. The fibular sesamoidectomy was performed by one of the three fellowship trained foot and ankle surgeons. All surgeons used plantar approach with a longitudinal incision on the lateral edge of the first metatarsal fat pad. Postoperatively, patients were kept non–weight bearing for 2 weeks and in a post-op walking shoe for 6 weeks. Results: Average age of the patients was 38 years. Ten of twelve patients (83%) were female. Majority of the patients (10) had no history of trauma, only two referred forefoot injury in the past. Average follow-up was 35 months. Two patients had both hallux valgus and hallux rigidus. One had preexisting rheumatoid arthritis with involvement of the first MTP. MRI showed 5 of 12 (42%) of patients had avascular necrosis of the sesamoid based on magnetic resonance imaging. None of the patients developed cock-up deformity of the lesser toes or hallux varus deformity, clinically or radiologically. Two patients experienced transient neuritis, one developed a superficial infection, and one had painful postoperative scarring. Hallux varus deformity was not observed in any patients. None underwent reoperation. Conclusion: Our study contradicts earlier studies which associate sesamoidectomy with high incidence of complications, particularly hallux varus. But, most of these earlier reports focus on combinations of medial, lateral, and paired excision, rather than lateral excision alone, unlike our study. Hence, fibular sesamoidectomy can be a safe, viable procedure for patients who fail conservative measures for sesamoiditis. The plantar lateral approach allows for adequate exposure of the fibular sesamoid, repair of the plantar plate, and preservation of flexor hallucis brevis, and is beneficial in preventing the occurrence of hallux varus deformity.

We present the short-term follow-up of 55 symptomatic hallux valgus deformities in 38 patients, treated operatively with a modification of the spike distal first metatarsal osteotomy, as described by Gibson and Piggott in 1962. The age range of the patients was 17 to 72 years at the time of surgery. The postoperative follow-up period was 12 to 55 months. Excellent and good clinical and radiographic results were recorded in 96.2% of our patients. Two of the patients (3.8%) were dissatisfied; one of them complained of metatarsalgia after the procedure, and the other had stiffness of the metatarsophalangeal joint and metatarsalgia that had been present before surgery. Three others (5.45%) required revision after early postoperative displacement but were asymptomatic subsequently. We concluded that our technique is an effective method of treating mild hallux valgus deformities with the advantages of simplicity, no shortening of the first metatarsal, and no risk of dorsal tilting of the distal fragment. Hallux valgus (lateral deviation of the great toe) is not a single disorder, as the name implies, but a complex deformity of the first ray that sometimes may involve the lesser toes. More than 130 procedures exist for the surgical correction of hallux valgus, which means that no treatment is unique. No single operation is effective for all bunions. 5 , 22 , 29 The objectives of surgical treatment are to reduce pain, to restore articular congruency, and to narrow the forefoot without impairing function, by transferring weight to the lesser metatarsals either by shortening or by dorsal tilting of the first metatarsal. 5 , 19 , 24 , 27 Patient selection is important for a satisfactory outcome after surgery of any kind, and our criteria were age, degree of deformity, presence of arthrosis, and subluxation of the first metatarsophalangeal joint. 1 , 5 , 13 , 19 – 21 , 24 , 29 In this study, we present a new method of treating hallux valgus that has been used at Mayday University Hospital since 1990. The technique was first described at the British Orthopaedic Foot Surgery Society, Liverpool, November 1990, 7 and we now present the short-term follow-up results. The procedure is essentially a modification of the spike osteotomy of the neck of the first metatarsal, as described by Gibson and Piggott. 9 It has the advantages of simplicity, no shortening of the first metatarsal, and no risk of dorsal displacement of the distal fragment.

Background. The aim of this study was to evaluate the mid- to long-term outcomes of metatarsal head resurfacing hemiarthroplasty in the surgical treatment of advanced-stage hallux rigidus. Methods. We performed a retrospective review of 57 consecutive patients (25 [43.9%] males, 32 [56.1%] females; mean age, 61.0 ± 6.4 years) who underwent first metatarsal head resurfacing hemiarthroplasty (HemiCAP) for hallux rigidus between August 2007 and September 2010. Sixty-five implantations were performed in 57 patients; 8 patients underwent bilateral procedures. All patients were clinically rated prior to surgery and at the final follow-up visit using the American Orthopaedic Foot and Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal scale and first metatarsophalangeal joint range of motion (MTPJ ROM). Results. The median follow-up duration was 81 (range = 8-98) months. The median preoperative AOFAS score was 34 (range = 22-59) points, which had increased to 83 (range = 26-97) points at the final follow-up visit (P < .001). The median preoperative first MTPJ ROM was 25° (range = 15° to 40°), which had increased to 75° (range = 30° to 85°) at the final follow-up visit (P < .001). Conclusions. First MTPJ hemiarthroplasty is an effective treatment method that recovers toe function and first MTPJ ROM, and provides good mid- to long-term functional outcomes.

First Ray

Today, bunion surgery is still controversial. Considering that a bunion deformity in fact may be a result of multiple causes, the rationale of the currently applied techniques of surgical treatment has not been conclusively demonstrated. In view of the known hypermobility syndrome of the first ray that results in insufficient weightbearing beneath the first metatarsal head, the relationship between this syndrome and hallux valgus deformity has been investigated. The results suggest a direct relationship between painful hallux valgus deformity and hypermobility in extension of the first tarsometatarsal joint. A pathological mechanism of symptomatic hallux valgus is proposed that relates this pathology with primary weightbearing disturbances in the forefoot where angulation of the first metatarsophalangeal joint is one of the consequences. The alignment of the metatarsal heads within the sagittal plane seems to be a main concern in many hallux valgus deformities. As a consequence, treatment includes reestablishing stable sagittal alignment in addition to the horizontal reposition of the metatarsal over the sesamoid complex. As an example, first tarsometatarsal reorientation arthrodesis regulates the elasticity of the multiarticular first ray within the sagittal plane and may be the treatment of choice in many hallux valgus deformities.
