Treatment for Freiberg's disease is largely conservative. For severe disease and refractory cases, there are various surgical options. Most studies are from the Far-Eastern population and have short follow-up. The purpose of this study was to report the 5 year clinical outcomes of a dorsal closing wedge osteotomy in the treatment of advanced Freiberg´s disease in a Caucasian population. Twelve patients (12 feet), with a mean age of 30.7 years (range 17–55), were treated with a synovectomy and a dorsal closing wedge osteotomy of the affected distal metatarsal. There were 10 females and 2 males. All patients were born in the United Kingdom. Clinical outcomes were independently evaluated pre and postoperatively using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system and a subjective satisfaction score. Nine (75%) feet involved the 2. nd. metatarsal and 3 feet (25%) involved the 3. rd. metatarsal. According to the Smillie classification, 6 feet were Grade IV and 6 feet were grade V. Radiological union was evaluated postoperatively. No patients were lost to follow up and the mean follow-up time was 5.2 years (4–7). AOFAS scores improved from 48.1 +/− 7.4 to 88.9 +/− 10.1 postoperatively (p< 0.001) giving a mean improvement of 40.8. 92% of patients were satisfied with their operation at latest follow-up, reporting excellent or good results. All patients had postoperative radiological union. One patient had a superficial postoperative infection that was successfully treated with oral antibiotics. A dorsal closing wedge osteotomy is an effective treatment of advanced Freiberg´s disease in a Caucasian population, with good outcomes and few complications

Aim. Forefoot ulcers in patients with diabetic neuropathy are a result of factors that result in increased forefoot plantar pressures. Progressive hindfoot equinus from contraction of gastrocnemius-soleus-tendo-Achilles complex and progressive plantar flexed metatarsal heads secondary to claw toe deformity results callus at the metatarsal heads which break down to ulceration. The aim is to describe 2-stage treatment pathway for managing these ulcers. Methods. Consecutive patients, who presented with forefoot ulcers since February 2019 were treated with a 2-stage treatment pathway. The first stage of this is an out-patient tendo-Achilles lengthening (TAL). The second stage is surgical proximal dorsal closing wedge metatarsal osteotomy for patients with persistent or recurrent ulcers. Patients were followed for a minimum of 12 months. Results. 112 patients (146 feet) underwent TAL by 3 consultants. Of these, 96 patients were followed for a minimum of 12 months (range 12–36 months). None had infection or wound related problems at the tenotomy sites; complete transection of the tendon was noted in 4 patients (4%) and one-patient developed heel callosity suggestive of over-lengthening. In 92 patients (96%), the ulcers healed within 10 weeks (± 4 weeks). Additional z-lengthening of peroneal longus and tibialis posterior tendons helped in patients with 1. st. metatarsal and 5. th. metatarsal head ulcers respectively. In 12 patients (10%), the ulcer failed to heal or recurred. MRI scan in these patients showed plantar flexed metatarsals from progressive claw toe deformity. The ulcer in this group healed after surgical offloading with proximal dorsal closing wedge osteotomy of the metatarsal/s, with no recurrence at a minimum 12months of follow-up. Conclusion. The described 2-stage treatment pathway results in long-term healing of neuropathic forefoot ulcers, and in 96% of patients, the ulcer healed after the first stage out-patient percutaneous TAL

Introduction. Freiberg's infarction poses a challenge to foot and ankle surgeons. Several surgical and non surgical treatment methods are described. We performed a dorsal closing wedge osteotomy, debridement and microfracture of the metatarsal head. Dorsal closing wedge osteotomy helps in bringing the smooth plantar articular surface of the metatarsal head to articulate with the phalangeal articular cartilage whilst offloading the damaged dorsal articular cartilage. Debridement and Microfracture of the metatarsal head helps in regeneration of the damaged cartilaage via subchondral stem cells. Materials and Methods. Total of 15 patients (12F, 3M) underwent the above surgery between year 2002 and 2008. Mean age was 35yrs (range14-60). All of them had an extraarticular dorsal closing wedge osteotomy fixed with a single screw along with debridement of the joint and mocrofracture of the damaged cartilage. Post operatively heel weight bearing was allowed with a special shoe for 6 weeks. Serial radiological assessments were done to assess healing of the osteotomy and reshaping of metatarsal head. Patients had a mean follow up of 2.5 yrs (Range 1-6). All patients were assessed using subjective patient satisfaction scores (scale 0-10) and AOFAS scores. Results. 2nd metatarsal was involved in 14 and 3rd in one patient. All the osteotomies healed at a mean period of 10 weeks (range6-18). The mean patient satisfaction score was 8 (range5-10). The mean pre and post operative AOFAS scores were 54 and 82. One patient developed post operative haematoma which resolved spontaneously. No other complications noted. Conclusions. A combination of dorsal closing wedge osteotomy, debridement and microfracture is a simple, reproducible and effective method of treating Freiberg's disease with no major complications

Introduction. The current treatment for Freiberg's osteochondrosis centres around either: simple debridement or debridement osteotomy. The main principle of the osteotomy is to rotate normal articular cartilage into the affected area. We recommend the use of CT scanning to delineate the amount of available, unaffected cartilage available to rotate into the affected space. Methods. We retrospectively reviewed 32 CT scans of new Freiberg's diagnoses in Sheffield over a 10 year period using the PACS system. We identified the sagittal CT slice that displayed the widest portion of proximal articular margin of the proximal phalanx and measured the diseased segment of the corresponding metatarsal head as an arc (in degrees). This arc segment was divided by 360°. This gave a ratio of the affected arc in the sagittal plane. Results. 28 out of 32 cases involved the 2nd metatarsal with the remaining 4 involving the 3rd metatarsal head. Of 32 cases, 18 had fragmentation. Surgically, 20 had debridement only, 5 also had an osteotomy and 1 had a fusion. 6 of the 32 cases were managed non-operatively. 11 cases out of 32 had an arc ratio of < 0.3. Of these, only 3 had an osteotomy, 3 had no procedure and 5 had a simple debridement. Of those that had osteotomies (5/32), 3 of the 5 cases had an arc ratio of < 0.3 with the other 2 being 0.42 and 0.38. Discussion. We hypothesise that those cases with an arc ratio of less 0.3 would be amenable to a dorsal closing wedge osteotomy and those with a ratio of more than 0.4 would be better suited to a simple debridement. For those cases between 0.3–0.4, we feel either option is viable. Further work to prove or disprove outcomes related to our classification is required

We reviewed the outcome of distal chevron metatarsal osteotomy without tendon transfer in 19 consecutive patients (19 feet) with a hallux varus deformity following surgery for hallux valgus. All patients underwent distal chevron metatarsal osteotomy with medial displacement and a medial closing wedge osteotomy along with a medial capsular release. The mean hallux valgus angle improved from −11.6° pre-operatively to 4.7° postoperatively, the mean first-second intermetatarsal angle improved from −0.3° to 3.3° and the distal metatarsal articular angle from 9.5° to 2.3° and the first metatarsophalangeal joints became congruent post-operatively in all 19 feet. The mean relative length ratio of the metatarsus decreased from 1.01 to 0.99 and the mean American Orthopaedic Foot and Ankle Society score improved from 77 to 95 points. In two patients the hallux varus recurred. One was symptom-free but the other remained symptomatic after a repeat distal chevron osteotomy. There were no other complications. We consider that distal chevron metatarsal osteotomy with a medial wedge osteotomy and medial capsular release is a useful procedure for the correction of hallux varus after surgery for hallux valgus

Introduction. In 1927, Lambrinudi described a variant triple fusion for the treatment of paralytic “drop foot”. This involved closing wedge osteotomies and fusion to correct the deformities predominantly caused by Polio. The eradication of Polio has seen a shift in its use to the correction of other complex hind foot deformities. The technique has relevance in modern Orthopaedics for other neurological and degenerate conditions. There have been few published series of this technique since 1927. We describe a series of 14 complex corrective triple arthrodeses to illustrate the power of Lambrinudi's concepts. We believe Lambrinudi's original description has relevance in terms of modern day complex hindfoot deformity correction

Introduction. Diabetes is increasing on a global scale. By 2030, 10% of the global population, ½ billon people, are predicted to have diabetes. Potentially there will be a corresponding increase in number of patients referred for surgery. Traditional surgical management of these patients is challenging. Presented is a case series utilizing Minimally Invasive Surgical Techniques of percutaneous metatarsal neck osteotomies, metatarsal head debridement, mid-foot closing-wedge osteotomies and hind-foot arthrodesis, for the surgical management of diabetic foot pathology. The potential socio-economic benefits analysis with regards to reduction in out-patient and theatre time, patient length of stay and time to healing are also postulated. Methods. Minimally Invasive Surgical Techniques of metatarsal neck osteotomy, metatarsal head debridement, closing wedge osteotomy, mid-fusion and hind-foot arthrodesis nailing are described. Procedures are preformed as day cases with fluoroscopic guidance. Low speed, high torque burrs and wedges, create the osteotomies, which can be held with percutaneous fixation. Comparative cost analysis of conservative treatment, including clinic visits, out-patient debridement, dressings, intravenous and oral antibiotics, versus Minimally Invasive Surgical Techniques is presented. Results. Six patients had metatarsal osteotomies for mechanical ulceration. Five reported good outcome. One patient required revision to forefoot arthroplasty due to mal-union. Five patients had debridement of metatarsal heads, which healed on average at six to eight weeks. Eight patients had mid-foot arthrodesis. Two infected cases required removal of metalwork. Three patients had hind-foot arthrodesis for arthritis following ankle fracture with degeneration and deformity. Patients had good short and early medium term outcomes, with no reports of below-knee amputation. This technique is reproducible once the initial learning curve is mastered. Comparative cost analysis, suggests significant financial savings by reducing inpatient admissions, clinic visits and theatre time. Conclusion. Minimally Invasive Surgical Techniques may provide an alternative surgical management for diabetic patient with foot and ankle pathology

Introduction. The aim of this study was to assess whether routine X-Rays at six weeks altered the subsequent management of patients who underwent a Scarf osteotomy. Materials and Methods. Between 1997 and 2010, 218 consecutive primary scarf osteotomies of the first metatarsal were performed by two foot and ankle surgeons in a single unit. 71 were combined with an Akin closing wedge osteotomy of the proximal phalanx of the great toe and soft tissue release. Additional osteotomies were performed on the lesser toes in 30 cases. Intraoperative X-Rays were taken. We retrospectively looked at clinic letters for all patients who attended six weeks post operatively and recorded the outcomes following X-Rays. Results. 209 patients were assessed six weeks post operatively with radiographs of the foot. 9 patients were lost to follow up. Four patients (1.9%) were identified as having complications at the osteotomy: recurrence of deformity seen in two patients, delayed union with failure of fixation, and painless hypertrophic nonunion. Discussion. Only a very small proportion of patients developed complications at the osteotomy site following a Scarf osteotomy for hallux valgus. Both cases of recurrence were diagnosed clinically. Failure of fixation was due to poor patient compliance. No revision procedures were planned for any patients. Conclusion. The senior author no longer requests postoperative X-Rays routinely. We believe that the majority of patients may be safely and successfully assessed clinically following Scarf osteotomy without the need for routine X-Rays

Introduction:. The dorsal closing wedge calcaneal osteotomy has been described for the treatment of insertional pathology of the tendo-achilles. The aim of this study was to evaluate the efficacy of the technique using outcome measures. Method:. This was a prospective case series. Patients were included if they had tendo-achilles insertional pathology (calcific tendonitis, bursitis or Haglund's deformity). A short extended lateral approach was used and a 1 cm dorsally based closing wedge osteotomy of the calcaneus performed. Fixation was with 2 staples. Patients were scored pre-operatively and at 6 and 12 months post-operatively using the VISA-A and AOFAS ankle-hindfoot scores. Results were analysed with the paired student t-test. Results:. Twenty five feet in 23 patients were enrolled in the study February 2011 – May 2013. 22 patients underwent the osteotomy (9 males and 14 females). Average age was 47.2 years (range 19–62 years). 12 feet have been followed up for 1 year, 6 for 6 months, 5 less than 6 months. Average VISA-A improvement was 27.87 points (−13–71) at 6 months p=0.001 and 38 (−13–81) at 12 months p=0.001. Average AOFAS improvement was 11 points (−8–31) at 6 months p=0.005 and 11 (−18–42) at 12 months p=0.04. 82.3% of patients would have the procedure again. Complications included minor wound problems (3), sural nerve symptoms (1) and plantar fasciitis (3). All complications have resolved. Conclusion:. The results of this study show that the use of the Zadek osteotomy of the calcaneus can provide consistent symptomatic relief from insertional Achilles pathology by altering the biomechanics of the tendon without disrupting the bursa. There is a small risk of minor complications, which should be included in the consent process

Most of the controversy surrounding management of the adult acquired flatfoot deformity revolves around the correction of Stage 2 deformity. Stage 1 deformity, uncommonly corrected surgically, involves tenosynovitis with preservation of tendon length and absence of structural deformity. Attempts at tenosynovectomy in light of structural deformity leads to operative failure, found in 10% of Teasdall and Johnson's 1992 patient population. Thus, with tenosynovectomy rarely becoming an operative situation, Stage 2 deformity becomes the mainstay of operative treatment of the adult flatfoot. Stage 2 deformity patients present with swelling medially, the inability to do a single heel raise, with a passively correctable subtalar joint. The tendon is functionally torn. In recent years, authors have subdivided Stage 2 deformity even further into A and B subcategories, where A involves less than 50% uncovering of the talonavicular joint, and B patients more than 50%. Recently, Anderson has added a C subtype, which may be applied to either A and B patients, in patients who have forefoot varus. Thus, Stage 2 patients suffer from pain that begins medially and progresses to the subfibular region over time. Most important, recognition of the continued sub classification in Stage 2 disease echoes the fact that this disorder is on a continuum, challenging the surgeon to recognize subtleties that, if unrecognized, lead to a poor patient outcome. The mainstay of treatment in Stage 2 disease is the medial slide calcaneal osteotomy, which realigns the hindfoot axis reducing valgus, improves the medial arch, protects the FDL tendon transfer, and allows the Achilles tendon to become a strong inverter. Over shift of the calcaneus can compromise the outcome, as will a lack of recognition of the congenital subtleties such that a valgus hindfoot can have a varus orientation to the calcaneus, both leading to lateral overload. A pure medial slide of a calcaneus that has a varus orientation does not correct deformity, rather, it creates it. Thus, an axial calcaneal view must be studied carefully, for a varus orientation may be corrected via a closing wedge osteotomy commensurate with the medial shift of the tuberosity. As noted above, the flexor digitorum longus tendon transfer is the staple procedure to replace the damaged posterior tibial tendon. This transfer balances the eversion power of the peroneal tendons, works in phase with the former posterior tibial tendon in the stance phase of gait, and replaces a painful diseased posterior tibial tendon. However, over tensioning the transfer results in a tenodesis rather than a functional tendon transfer, the relative weakness of the FDL tendon (30% as strong as the PTT) creates difficulty with heel raise, and inappropriate transfer to distal tarsal bones may compromise the result by limiting torque from the transferred tendon. Preservation of the posterior tibial tendon in combination with the transferred FDL tendon remains a consideration without answer, though Rosenfeld (2005) suggests a substantial improvement in strength through PTT preservation. Failure of the above protocol for treating Stage 2 disease most often revolves around the insufficient corrective power of the tandem procedures in longstanding ruptures. According to Guyton (2001), only 50% of patients report a perception in deformity improvement following FDL/calcaneal osteotomy procedures, and only 4% report a significant improvement in pre-existing deformity. Sangeorzan (2001) found such patients could not achieve a painless plantigrade foot due to acquired ligament laxity (primarily the Spring Ligament). Sangeorzan applied Evans' pediatric procedure to adults without confirming the pathomechanics of correction. Some speculate the windlass effect on the plantar fascia creates correction (refuted by Horton, 1998, finding the plantar fascia is loosened by a lateral column lengthening), others believe tightening the peroneus longus through lateral column lengthening increases first ray plantarflexion, restoring the medial arch. Controversy also remains in answering Cooper's (1997) claim that lengthening through the calcaneus creates static increase in pressure about the calcaneocuboid joint (1.4mPa total) that may lead to an arthritic joint long term. Painful lateral overload following lateral column lengthening remains difficult problem to both prevent and correct. This last point leads to some focusing their efforts on restoration of the medial column. This group focuses on the “C” type deformity noted by Anderson, those with forefoot varus. It is known that the medial column is supported by the navicular, the cuneiforms, and the first, second, and third metatarsals. While a Cotton (opening wedge medial cuneiform) osteotomy, a first tarsometatarsal joint arthrodesis, or a metatarsal osteotomy has value, the surgeon must note that this only corrects the first ray. Complete correction of the medial column is best achieved through naviculocuneiform joint arthrodesis. Standing radiographs commonly reveal collapse at that level; however, surgeons are reticent to perform such fusions in light of the higher nonunion rate

As it remains unproven that hypermobility of the first tarsometatarsal joint (TMTJ-1) is a significant factor in hallux valgus deformity, the necessity for including arthrodesis of TMTJ-1 as part of a surgical correction of a hallux valgus is questionable. In order to evaluate the role of this arthrodesis on the long-term outcome of hallux valgus surgery, a prospective, blinded, randomised study with long-term follow-up was performed, comparing the Lapidus procedure (which includes such an arthrodesis) with a simple Hohmann distal closing wedge metatarsal osteotomy. The study cohort comprised 101 feet in 87 patients: 50 feet were treated with a Hohmann procedure and 51 with a Lapidus procedure. Hypermobility of TMTJ-1 was assessed pre-operatively by clinical examination. After a mean of 9.25 years (7.25 to 11.42), 91 feet in 77 patients were available for follow-up. There was no difference in clinical or radiological outcome between the two procedures. Also, there was no difference in outcome between the two procedures in the subgroup clinically assessed as hypermobile. This study does not support the theory that a hallux valgus deformity in a patient with a clinically assessed hypermobile TMTJ-1 joint requires fusion of the first tarso-metatarsal joint.

Aims

Preoperative talar valgus deformity ≥ 15° is considered a contraindication for total ankle arthroplasty (TAA). We compared operative procedures and clinical outcomes of TAA in patients with talar valgus deformity ≥ 15° and < 15°.

Aims

There is little information about how to manage patients with a recurvatum deformity of the distal tibia and osteoarthritis (OA) of the ankle. The aim of this study was to evaluate the functional and radiological outcome of addressing this deformity using a flexion osteotomy and to assess the progression of OA after this procedure.

Aims

The mainstay of surgical correction of hallux valgus is first metatarsal osteotomy, either proximally or distally. We present a technique of combining a distal chevron osteotomy with a proximal opening wedge osteotomy, for the correction of moderate to severe hallux valgus.

Aims

The aim of this study was to report a single surgeon series of consecutive patients with moderate hallux valgus managed with a percutaneous extra-articular reverse-L chevron (PERC) osteotomy.

The purpose of this study was to compare the results of proximal and distal chevron osteotomy in patients with moderate hallux valgus.

We retrospectively reviewed 34 proximal chevron osteotomies without lateral release (PCO group) and 33 distal chevron osteotomies (DCO group) performed sequentially by a single surgeon. There were no differences between the groups with regard to age, length of follow-up, demographic or radiological parameters. The clinical results were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system and the radiological results were compared between the groups.

At a mean follow-up of 14.6 months (14 to 32) there were no significant differences in the mean AOFAS scores between the DCO and PCO groups (93.9 (82 to 100) and 91.8 (77 to 100), respectively; p = 0.176). The mean hallux valgus angle, intermetatarsal angle and sesamoid position were the same in both groups. The metatarsal declination angle decreased significantly in the PCO group (p = 0.005) and the mean shortening of the first metatarsal was significantly greater in the DCO group (p < 0.001).

We conclude that the clinical and radiological outcome after a DCO is comparable with that after a PCO; longer follow-up would be needed to assess the risk of avascular necrosis.
