“…Reduction problems or recurrence can also be seen due to fixation complications (6,16,22). The application of an ILP has some advantages over other methods, in terms of union, stability, and recovery time, as well as the complication rates, which are more likely to be reduced (23). In our study this fixation method showed not only radiological, but also clinical improvement.…”

“…ILP provides strong fixation on osteotomy site, early bone bridging and weight-bearing. Compared to other endolog implants, the main disadvantage is that the locking screws, which are inserted into the metatarsal cottage in osteoporotic patients, can create fissures in the cortex, but this can be prevented with cerclage wires (23). This complication developed in 2 patients of the current study but they had no complaints of discomfort or unstable fixation.…”

Aim: Hallux valgus is a complex deformity of the first metatarsophalangeal joint characterized by varus deformity of the first metatarsal bone, valgus deformity of the big toe, and lateral deviation of the extensor tendons and sesamoid bones. Several surgical methods have been described for correction of the deformity. Distal metatarsal osteotomy is a commonly used procedure in mild-to moderate hallux valgus. Different materials have been used for the fixation of osteotomy. The aim of this study was to evaluate radiological and clinical efficacy of intramedullar locking plate in hallux valgus surgery. Material and Methods: Postoperative 6 th month data of patients with mild-to moderate hallux valgus deformity who underwent distal metatarsal osteotomy using an intramedullary locking plate between 2012 and 2014 were evaluated retrospectively. The surgical procedure was applied by Mitchell technique. Clinical and radiological features of the patients were analyzed. Results: Thirty-six (29 female, 7 male) patients whit a mean age of 51.00±12.96 years were enrolled the study. Eight patients underwent bilateral surgery. There were statistically significant improvement in hallux valgus angle, distal metatarsal articular angles, and American Orthopaedic Foot and Ankle Society hallux valgus scores in the postoperative 6 th month (all p values <0.001). No statistically significant difference were found between the preoperative and postoperative 6 th month inter-metatarsal angle values (p=0.058). Conclusion:The intramedullar locking plate usage in surgery of mild-to moderate hallux valgus deformity is an effective method providing strong fixation and quick recovery that led patients to gain an early improvement in the daily life activities. Keywords: Hallux valgus; intramedullar locking plate; distal metatarsal osteotomy. ÖZAmaç: Halluks valgus, birinci metetarsal kemiğin varus deformitesi, başparmağın valgus deformitesi, sesamoid kemikler ve ekstensör tendonların laterale yer değiştirmesi ile karakterize, birinci metatarso-falangial eklemin kompleks deformitesidir. Bu deformitenin düzetilmesi için çeşitli cerrahi yöntemler tarif edilmiştir. Distal metatarsal osteotomi hafif orta evre halluks valgus cerrahisinde en sık kullanılan yöntemlerden biridir. Metatars osteotomi hattının fiksasyon materyali olarak çeşitli implantlar kullanılmaktadır. Bu çalışmanın amacı halluks valgus cerrahisinde intrameduller plak uygulamasının kısa dönem klinik ve radyolojik sonuçlarını ortaya koymaktır. Gereç ve Yöntemler: 2012-2014 yılları arasında distal metatarsal osteotomi sonrası osteotomi hattı intramedüller kilitli plak kullanılarak tespit edilen halluks valgus hastalarının operasyon sonrası 6. ay verileri retrospektif olarak değerlendirildi. Cerrahi yaklaşım olarak Mitchell distal metatarsal osteotomi tekniği uygulandı. Hastaların klinik ve radyolojik özellikleri incelendi. Bulgular: Çalışmaya yaş ortalaması 51,00±12,96 yıl olan toplam 36 (29 kadın, 7 erkek) hasta dahil edildi. Sekiz hastaya her iki ayağından cerrahi uygulandı. Ameliyat ...

“…Multiple retrospective studies have reported the results of many different techniques proposed for HV correction, but, to the best of our knowledge, this is the first prospective study reporting the outcome of the Endolog technique at the 4 year follow-up. Only one retrospective study [ 22 ] showing midterm outcome of this device has been published.…”

Endolog technique for correction of hallux valgus: a prospective study of 30 patients with 4-year follow-up

BackgroundHallux valgus (HV) is a complex deformity of the forefoot altering the kinematics of walking. Many different treatment alternatives exist for the correction of hallux valgus, but to date, none has been shown to be more effective than any other. The rate of complications following hallux valgus surgery is variable and has been reported as ranging from 1 to 55 % in the scientific literature. The purpose of this preliminary prospective study was to evaluate the result of the Endolog device, an innovative titanium endomedullary nail, for the treatment of HV.MethodsThirty patients with mild-to-severe HV were treated with the Endolog device. Clinical evaluation was assessed preoperatively, as well as at 3, 6, 12, 24, and 48 months after surgery with a final follow-up at 4 years, using the American Orthopaedic Foot and Ankle Society (AOFAS) hallux grading system. Computer-assisted measurement of weight-bearing antero-posterior radiographs was taken preoperatively and postoperatively, as well as at 3, 6, 12, 24, and 48 months after surgery. Non-weight-bearing radiographs were taken before the patients were discharged. The radiological parameters measured included the intermetatarsal angle (IMA), the hallux valgus angle (HVA), the distal metatarsal articular angle (DMAA), and the tibial sesamoid position. Statistical analysis was carried out using the paired t test (p < 0.05).ResultsThe mean AOFAS score was 93.98 points at the 48-month follow-up. The postoperative radiographic assessments showed a statistically significant improvement compared with preoperative values. The mean corrections for each angular value at the last follow-up were as follows: IMA 5.95°; HVA 16.81°; DMAA 10.70°; and tibial sesamoid 1.36°.ConclusionThe Endolog is a safe and effective technique for the correction of HV deformity, to relieve pain and to preserve joint movement.

“…The most important finding of the study was that the MI LR of the first MTP joint was a safe and reliable technique that was performed in cadavers without damaging any neurovascular structures or articular cartilage.

Background: Lateral release (LR) for the treatment of hallux valgus is a routinely performed technique, either by means of open or minimally invasive (MI) surgery. Despite this, there is no available evidence of the efficacy and safety of MI lateral release. Our aim was to study 2 popular techniques for MI LR in cadavers by subsequently dissecting the released anatomical structures. Methods: Twenty-two cadaveric feet were included in the study and allocated into 2 groups, 1 for each procedure: 1 group underwent a MI adductor tendon release (AR), and in the other group, an extensive percutaneous lateral release (EPLR) (adductor tendon, suspensory ligament, phalanx-sesamoid ligament, lateral head of flexor hallucis brevis, and deep transverse metatarsal ligament) was performed. Anatomical dissection was performed to identify neurovascular injuries and to verify the released structures. Results: Both techniques demonstrated to be effective in reproducing a MI LR. A satisfactory release of the adductor tendon was achieved equally in both techniques ( P = .85), being partial in most EPLR cases and full in the majority of AR cases. The EPLR was successful in releasing the intended additional structures ( P < .05). One case of inadvertent complete section of the flexor hallucis longus was identified in the percutaneous adductor tendon release group. No cases of dorsolateral nerve injury were seen with either of the techniques. Conclusion: Percutaneous lateral release was a reliable and accurate technique in this cadaveric model. The MI AR proved to be more effective in fully releasing the adductor tendon while the ER was intended and able to release a number of other structures. Clinical Relevance: MI LR is a safe procedure that could obviate the need for open surgery to achieve the same surgical goal. It can be associated to either open or MI osteotomies in the correction of hallux valgus.
