ABSTRACT

BACKGROUND: In the field of minimally invasive surgery (MIS) for the treatment of hallux valgus (HV), different techniques have begun to emerge in the literature concerning the distal osteotomy of the first metatarsal bone, the synthesis or not of the metatarsal head, the possible association with lateral soft tissues release (LSTR) and osteotomy of the base of the first phalanx. AIM: To evaluate the role of LSTR on percutaneous HV correction, evaluating functional and radiographical results. METHODS: From January 2012 to May 2016 a total of 396 patients with mild to moderate symptomatic HV treated with the MIS technique were included in this retrospective study. The technique provides no internal fixation (WOS). Patients were divided into the LSTR group and no LSTR group (LSTR N). This surgical procedure (LSTR) was reserved for insufficient HV angle (HVA) correction during fluoroscopic control. Patients were evaluated at each follow-up by two other authors after appropriate training by senior authors (first practitioners). Clinical evaluation was performed before surgery, 6 mo after surgery, and 48 mo follow-up. American Orthopaedic Foot and Ankle Society (AOFAS) and visual analog scale (VAS) score was used to evaluate pain and function, and complications were recorded. In addition, the incidence of relapses and the degree of joint range of motion (ROM) with the association with the LSTR (capsule, adductor tendon, phalanx-sesamoid ligament, and the deep transverse metatarsal ligament) were evaluated. Radiological parameters included HVA and intermetatarsal angle (IMA). Patient satisfaction was assessed. Student t-test and Fisher exact test were used to assess statistical analysis. RESULTS: From our study it is clear that no differences in term of HVA, VAS, IMA correction, rate of complications, and AOFAS score were found between groups, while a significant improvement of the same variables was found in each group between pre and postoperative values. A significant improvement in ROM at 6 mo (P = 0.018) and 48 mo (P = 0.02) of follow-up was found in LSTR N group. Complications were rare in both groups. CONCLUSION: LSTR procedure on percutaneous HV correction seems to increase postoperative joint stiffness with a comparable incidence of relapse and a low incidence of complications.

ABSTRACT

Background: Within a timeframe of 8 years (2008-2016), 38 patients have undergone total hip replacement surgery for coxarthrosis or aseptic necrosis secondary to acetabulum fractures. Materials and Methods: The study included 27 males and 11 females between 42 and 70 years of age, all of whom came from other institutions. The follow-up period ranged between a minimum of 4.6 and a maximum of 9.7 years. Results: At the final follow-up, all patients were evaluated using the Merle D'Aubigne and Pastel model. Optimal results were found in all the cases. Three patients benefited from surgical revisitation with implant exchange following infection and one/two state reimplatation at seven, fourtheen et twenty-seven months respectively. Two patients benefited from cotyle revision due to chronic instability of the implant. Conclusions: The scope of the study was to present all the possible surgical difficulties that can come up with prosthetic implants. More particularly, hip implants after acetabulum fractures qualifies as a "difficult primary implant".
