State of the Art in Lesser Metatarsophalangeal Instability

Advancements in lesser metatarsophalangeal (MTP) instability have involved the use of minimally invasive surgery techniques, synthetic augmentation of existing transfers, and use of arthroscopy for both diagnosing and addressing MTP disorder. Advances in imaging modalities, particularly MRI, have aided in diagnosing subtle instability. Clinical outcomes seem to be similar to traditional approaches as the indications and applicability continue to evolve.

This study compares the short-term clinical and radiographic outcome between conventional and minimally invasive posterior approaches in total hip arthroplasty. Study Design &Methods We conducted a prospective, comparative pilot study containing 30 patients who underwent primary total hip arthroplasty between January 2017 and May 2017, 15 of them were operated through a conventional posterior approach and the other 15 were operated upon using a minimally invasive posterior approach. The exclusion criteria were severe protrusio or acetabular dysplasia as well as severe obesity (more than 120 kg body weight or a body m...

Knee arthroscopy is a minimally invasive surgery used in the treatment of intra-articular knee pathology which may cause unintended damage to femoral cartilage. An ultrasound (US)-guided autonomous robotic platform for knee arthroscopy can be envisioned to minimise these risks and possibly to improve surgical outcomes. The first necessary tool for reliable guidance during robotic surgeries was an automatic segmentation algorithm to outline the regions at risk. In this work, we studied the feasibility of using a state-of-the-art deep neural network (UNet) to automatically segment femoral cartilage imaged with dynamic volume...

Publication date: Available online 19 September 2019Source: Arthroscopy TechniquesAuthor(s): Kai Man Chu, Tun Hing LuiAbstractSubfibular impingement is a common cause of lateral heel pain after calcaneal fracture. It can be caused by calcaneofibular impingement, peroneal impingement, or a combination thereof. It may not be easy to differentiate bony impingement from soft-tissue impingement. Simultaneous lateral calcaneal ostectomy and peroneal tendon decompression may increase the chance of pain relief. The purpose of this Technical Note was to report the technical details of endoscopic lateral calcaneal ostectomy and pero...

The ossicle is sometimes symptomatic and presents with local pain or lateral ankle instability. The purpose of this Technical Note is to describe the details of arthroscopic stabilization of the os subfibulare. It is indicated for symptomatic mechanical lateral ankle instability resulting from an unstable os subfibulare. The technique has the advantages of minimally invasive surgery, evaluation and treatment of concomitant an...

Publication date: Available online 11 September 2019Source: Arthroscopy TechniquesAuthor(s): Yue Ting Ophelia Wan, Tun Hing LuiAbstractOsteochondral lesions of the talar head can be classified into 4 types according to their location. A type 1 lesion is located at the anterior part of the talar head. Surgical debridement and microfracture are indicated for symptomatic type 1 lesions if conservative treatment fails to relieve the pain. The purpose of this technical note was to describe the details of arthroscopic debridement and microfracture of the symptomatic type 1 osteochondral lesion of the talar head and the kissing l...

The algorithm of arthroscopic reduction and minimally invasive surgery (ARMIS) can decrease the incidence of complications and reoperations, in spite of longer operative times and higher doses of irradiation for the patients with a supination –external rotation ankle fracture. At the present time, however, we cannot identify which procedure contributes to improved outcomes with use of the ARMIS algorithm.

ConclusionChronic ankle instability with concomitant injury of both the ATFL and CFL, can be successfully treated by an arthroscopic all-inside repair. The clinical relevance of the study is the description of the first arthroscopic all-inside ATFL and CFL anatomic repair technique, which offers excellent clinical results and the inherent benefits from minimally invasive surgery.Level of evidenceIV, retrospective case series.

In this study we aim to show that an optical fiber Bragg grating-based microindentation system, which has the potential to be deployed arthroscopically, can differentiate between healthy and degenerated articular cartilage, which represents an important challenge in minimally-invasive surgery. DESIGN: Twenty bovine osteochondral cylinders, extracted from the patellar groove of ten 24 months old animals were subjected to stepwise in vitro stress-relaxation indentation measurements. The indentation procedure comprised 15 indentation steps of 20 μm each, reaching a total depth of 300 μm. Ten samples remained un...

Jnl Wrist Surg DOI: 10.1055/s-0039-1693146 Purpose Minimally invasive techniques have been recommended in the treatment of painful but stable scaphoid nonunions. The purpose of this study was to determine if arthroscopically assisted bone grafting provided superior results in healing as compared to percutaneous screw fixation. Materials and Methods One hundred sixty-four consecutive patients with scaphoid nonunions were retrospectively analyzed. One hundred forty-eight patients were treated with the open grafting techniques either with iliac or distal radius bone, leaving 16 patients treated with minimally ...
