Arthroscopy-Assisted Scapholunate Reconstruction With Internal Brace Augmentation.

Various surgical techniques exist to repair or reconstruct complete scapholunate (SL) interosseous ligament tears, including capsulodesis, static or dynamic tenodesis, ligament reconstruction with tendon graft, bone-retinaculum-bone reconstruction, and the reduction and association of the scaphoid and lunate (RASL) procedure. The choice of surgical technique depends on arthroscopic assessment using the Geissler classification and European Wrist Arthroscopy Society staging of SL injury. This article describes arthroscopy-assisted extracapsular SL reconstruction using free tendon graft and internal brace augmentation for the treatment of unrepairable complete SL interosseous ligament tears.

Recognizing and Treating Unique Distal Radius Fracture Patterns that are Prone to Displacement.

An unstable distal radius fracture is one that is not capable of resisting displacement after initial closed reduction. The challenge in managing distal radius fractures is identifying which fractures are prone to displacement. Currently, there are no standard criteria for assessing the stability of distal radius fractures. The fracture pattern and patient characteristics should be taken into consideration when treating distal radius fractures. This article discusses how to recognize and manage distal radius fractures that are prone to displacement.

Corrective Osteotomies for Digital Overlap in Phalangeal and Metacarpal Fracture Malunion Using Wide Awake Local Anesthesia No Tourniquet (WALANT) Technique: A Technical Note.

The use of wide-awake local anesthesia with no tourniquet (WALANT) in surgical procedures of the hand is well described and extends to tendon surgery, carpal tunnel release, trapeziectomy and phalangeal fracture fixation. Its use has not been described in corrective osteotomies of phalangeal or metacarpal fracture malunion. In our series of five patients who underwent phalangeal and metacarpal osteotomies under WALANT, all of the patients achieved union at a mean of 3.5 months and were satisfied with the results. All digital malrotations were corrected. There was an improvement of motion and grip strength by 24% and 29.3% respectively compared to pre-surgery. Corrective osteotomies under WALANT is a safe and effective means of achieving correction of scissoring. With the patient wide awake and cooperating, precise correction of rotational alignment can be ascertained. Concomitant tenolysis allows motion gains to be made over and above the restoration of rotational alignment.

CaproGlu: Multifunctional tissue adhesive platform.

Driven by the clinical need for a strong tissue adhesive with elastomeric material properties, a departure from legacy crosslinking chemistries was sought as a multipurpose platform for tissue mending. A fresh approach to bonding wet substrates has yielded a synthetic biomaterial that overcomes the drawbacks of free-radical and nature-inspired bioadhesives. A food-grade liquid polycaprolactone grafted with carbene precursors yields CaproGlu. The first-of-its-kind low-viscosity prepolymer is VOC-free and requires no photoinitiators. Grafted diazirine end-groups form carbene diradicals upon low energy UVA (365 nm) activation that immediately crosslink tissue surfaces; no pre-heating or animal-derived components are required. The hydrophobic polymeric environment enables metastable functional groups not possible in formulations requiring solvents or water. Activated diazirine within CaproGlu is uniquely capable of crosslinking all amino acids, even on wet tissue substrates. CaproGlu undergoes rapid liquid-to-biorubber transition within seconds of UVA exposure-features not found in any other bioadhesive. The exceptional shelf stability of CaproGlu allows gamma sterilization with no change in material properties. CaproGlu wet adhesiveness is challenged against current unmet clinical needs: anastomosis of spliced blood vessels, anesthetic muscle patches, and human platelet-mediating coatings. The versatility of CaproGlu enables both organic and inorganic composites for future bioadhesive platforms.

Techniques for Continuous Irrigation of Septic Joints of the Hand.

Septic arthritis of the small joints of the hand usually occurs secondary to bacterial inoculation through penetrating injury to the joint, or direct spread of infection from paronychia, felon, or pyogenic flexor tenosynovitis. Surgical treatment involves drainage and irrigation and may involve debridement if there is an open wound. We describe a method of continuous irrigation of septic joints of the hand postoperatively in the ward setting using an intravenous cannula placed within the joint and connected to an intravenous giving set with delivery of physiological fluid using a pump driver. Modifications of the technique are described for distal interphalangeal, proximal interphalangeal, and metacarpophalangeal joints and illustrated in each joint by 3 case studies. In addition to the irrigation, intravenous antibiotics were administered. All patients healed well with a full return of joint motion, no radiologic change, and a mean QuickDASH score of 4.8 at a mean follow-up duration of 3.6 months. This is a safe and simple technique that can be performed in patients with suspected or confirmed septic arthritis and carries minimal morbidity.

Minimally Invasive Palmaris Longus Abductorplasty for Severe Carpal Tunnel Syndrome.

Camitz abductorplasty is the most commonly used tendon transfer in patients with severe carpal tunnel syndrome with significant muscle wasting and loss of opposition. This procedure requires a long incision in the palm to harvest a strip of palmar aponeurosis to lengthen the palmaris longus tendon, allowing it to reach the abductor pollicis brevis insertion. Several complications have been attributed to this extensive dissection in the palm. We describe a minimally invasive palmaris longus abductorplasty using a strip of free flexor carpi radialis tendon graft to achieve the necessary length. This can be done together with carpal tunnel release in patients with severe carpal tunnel syndrome.

Audit of Clinical and Functional Outcomes of Arthroscopic Resection of Wrist Ganglions.

BACKGROUND: The purpose of this study is to audit the clinical and functional outcomes of arthroscopic ganglionectomy (AG) in our centre. METHODS: A retrospective study was conducted on all 29 patients who underwent AG from 2007 to 2012 with a mean clinic and telephone follow-up duration of 6 months and 32 months respectively. RESULTS: A total of 29 patients (17 women and 12 men) with a mean age of 38 years underwent AG. 15 patients (52%) had associated pain with the lump, 24 out of 29 patients (83%) had preoperative ultrasound to confirm the diagnosis. All patients had preoperative wrist radiographs that showed no chronic carpal instability and bony pathology. 26 out of 29 patients (90%) had dorsal wrist ganglions and 3 patients (10%) had volar wrist ganglions. 15 out of 24 ganglions (62.5%) were multiloculated. Mean ganglion size clinically and through wrist ultrasound was 2.5 cm and 1.8 cm respectively. During arthroscopy, ganglion stalk was identified in 14 patients (48%). Average operating time was 69.5 minutes. Intraoperatively, 24 out of 29 patients (83%) had wrist synovitis and 26 patients (90%) had associated carpal ligament laxity. 97% of cases were successfully resected arthroscopically. Recurrence rate was 10% (3 cases). There was no significant difference between preoperative and postoperative range of motion of wrists - the mean wrist flexion ranged from 63 to 59 degrees pre and postoperatively, and the mean wrist extension ranged from 66 to 64 degrees pre and postoperatively. Overall grip strength improved from 27 kg to 32 kg ([Formula: see text]), and there was also a significant improvement in pain scores pre and post-operatively from visual analogue scale (VAS) score of 0.8 to 0.3 ([Formula: see text]). No major intra or post-operative complications occurred. All patients were satisfied in terms of cosmesis. CONCLUSIONS: AG is a safe and reliable alternative to open resection of wrist ganglions. In addition, it can be used as a diagnostic and therapeutic tool for other wrist conditions.

The lateral lesser toe fillet flap for diabetic foot soft tissue closure: surgical technique and case report.

Wound closure for the diabetic foot can be challenging and often involves amputation or reconstruction. The authors describe a surgical technique and a case report of lateral lesser toe fillet flap in the management of a diabetic foot wound. The lateral lesser toe fillet flap reconstruction is a reproducible technique that incurs comparatively minimal technical complexity and provides a favorable option in the management of diabetic foot wounds where soft tissue coverage is required.

Crescent flap for fingertip reconstruction.

A volar advancement flap based on V-Y concept for fingertip reconstruction is described. The crescent flap utilises curved incision to preserve fingertip contour and distal digital crease. Satisfactory outcome was achieved in two patients who underwent fingertip reconstruction using this technique. Its advantages are technical simplicity, minimal donor morbidity, and may be used in situation where conventional V-Y incision is unsuitable.
