Punching injuries to the hand are frequent and can result in fourth and fifth carpometacarpal (CMC) fracture-dislocations. Fourth and fifth CMC fracture-dislocations are unstable, and dorsal metacarpal dislocations are most common. Operative management for maintaining reduction of the unstable fracture-dislocation was closed reduction and percutaneous pinning; however, in delayed fractures, open reduction is necessary. We report on a plating technique used for acute and delayed, unstable fourth and/or fifth CMC fracture-dislocations. This method of plating is novel and allows for physiological motion at the CMC joint through a dorsal buttressing mechanism while maintaining joint reduction. The range of motion begins within the first week postoperatively, and full composite fist formation and digital extension occur 4 to 6 weeks postoperatively. This novel technique affords an alternative effective surgical treatment option with excellent outcomes for patients presenting with fourth and fifth CMC fracture-dislocations up to 12 weeks following the injury.

Septic arthritis of the metacarpophalangeal joint (MCPJ) compromises 9% of hand infections in Singapore. Common surgical treatment is open arthrotomy and joint washout. The wound is often left open for drainage postoperatively. Repeated debridement and secondary closure are frequently needed after the index surgery. We describe a method of continuous catheter irrigation of septic MCPJ joint using an infant feeding catheter. This method provides great infection clearance to avoid repeated debridement and allows primary closure of the wound to avoid secondary closure. This method also significantly reduces postoperative pain so that to facilitate early mobilization of the joint, which is crucial for functional recovery. We illustrate the techniques of this procedure and key points of postoperative management in the ward with case examples to demonstrate its simplicity, safety, and efficacy in treating MCPJ septic arthritis.

The ulnar shortening osteotomy (USO) is a common procedure used to treat ulnar impaction syndrome secondary to static or dynamic ulnar-positive variance. There are many described techniques for the USO. The distal metaphyseal ulnar shortening osteotomy (DMUSO) with retrograde cannulated screw fixation was described to reduce complications seen with other techniques. Biomechanical analysis of fixation constructs demonstrates 2-screw constructs are significantly stiffer than 1 screw and antegrade constructs have similar or greater stiffness when compared with retrograde constructs. Here, we describe a technique of antegrade cannulated screw fixation for DMUSO that obviates the need for the disruption of the distal radioulnar joint for intra-articular exposure of the ulnar head. Similar to the traditional retrograde DMUSO technique, this construct may also decrease the risk of delayed union, symptomatic implants associated with diaphyseal osteotomies, and disruption of triangular fibrocartilaginous complex in wafer procedures.

A fracture of the tip of the coracoid is a rare but challenging fracture. A surgical indication is required in case of a displaced fracture. Screws and suture anchors often do not offer a reliable fixation in the case of very small fragments. We describe our hardwareless technique that consists of an osteosuture with a 90-degree suture threads configuration that we called the x-mas box technique. This procedure is cost-effective and it provides stable fixation and low complications rate.

The suture button (SB) suspension technique has become popular in the treatment of thumb basal joint arthritis, as it works as an internal mean for metacarpal stabilization, demonstrating good results with improvement in function and strength. The aim of our study is to describe a new transosseous suture suspensionplasty technique using a simple Ethibond #2 suture as a substitute for the suture button and to report the postoperative clinical outcomes. In this study, we included a total of 14 patients with 2 years follow-up. We evaluated patients with the use of the Disabilities of the Arm, Shoulder and Hand questionnaire, the Visual Analog Scale, the Kapandji test, and the key pinch strength. Patients treated with transosseous suture suspensionplasty demonstrated clinical improvement at an average follow-up of 24 months. No complications were noted immediately after the procedure or during the 2-year follow-up period.

Various surgical techniques are available for the alleviation of symptoms in carpal tunnel syndrome and each of them has its pros and cons. This study was designed and performed to present a novel approach for cutting transverse carpal ligament by the thread looping technique without the use of ultrasonography. The novel modification of looped threaded carpal tunnel release was performed on 10 hands of 10 patients. The disabilities of arm, shoulder, and hand score, visual analog scale, and 2-point discrimination were used for assessing the outcomes. No patients developed pillar pain or scar discomfort after surgery. Complete elimination of paresthesia, pain, and numbness occurred in all patients. There was a significant reduction in the disabilities of arm, shoulder, and hand and visual analog scale scores ( P value<0.05). This technique is safe, available, and effective for carpal tunnel release and minimizes postoperative complications, such as pillar pain, and scar discomfort with avoiding unnecessary injuries to the surrounding soft tissue.

Trigger finger surgery is a commonly performed open procedure with known potential complications of infection, stiffness, pain, nerve injury, bowstringing, and incomplete release of the A1 pulley. We present a novel single-incision endoscopic trigger finger release technique that moves the incision from the palm to the palmar-digital crease, leading to less pain, scarring, and stiffness. We believe that this technique is technically simple, fast, and may decrease the risk of complications commonly encountered with open trigger finger release. Level of Evidence: Therapeutic IV.

Optimal surgical treatment of first carpometacarpal joint instability remains a subject of debate. Consensus on thumb carpometacarpal stability originating with the dorsoradial ligamentous complex has shifted reconstruction techniques towards stabilization dorsally. We describe a dorsal stabilization technique with internal brace augmentation of the dorsoradial ligamentous complex. A single fellowship-trained hand surgeon treated 10 women, average age 34 years (range, 21 to 52 y) and 1 man, age 34 years, between 2019 and 2022. Average patient follow-up was 2 years. Patient satisfaction was high. Further trials are needed to determine whether the procedure will prevent or delay the presentation of thumb carpometacarpal arthrosis.

Managing lateral soft tissue defects, distal to the proximal interphalangeal joint, of the finger can be challenging. The use of antegrade homodigital island flap can be limited due to the length of the defect. Using a heterodigital island flap can be precluded by an injury in the adjacent fingers. Using the locoregional flap from the hand can result in a more extensive soft tissue dissection, which can create additional donor site morbidity. We present our execution technique of the homodigital dorsal skin advancement flap. The pedicle of the flap is based on dorsal branches of the digital artery perforator; hence the proper digital artery and nerve are unharmed. The operation is limited only to the injured digit, which can reduce donor site morbidity.

Substance tears of the triangular fibrocartilage complex (TFCC) can occur secondary to trauma of the wrist. On the dorsal periphery, they are considered Palmer 1B tears or Atzei class 1 tears. If along the radial side, they can manifest as a tear of the central disc, classified as a Palmar class 1A tear. If it involves the ligaments, it is stated as a pre-1D tear as per the new classification system by Luchetti and colleagues. Multiple excellent repair techniques exist in the current literature for dorsal peripheral tears and even for those in the substance of the TFCC, whereas there are successful evolving techniques of repair of avulsed tears and those involving the substance of the ligaments on the radial side adjacent to the sigmoid notch. Here, we describe our technique of repairing substance tears of the TFCC arthroscopically without the need for any specialized equipment apart from the basic arthroscopy set. The technique was conducted in a patient with a transverse substance tear on the radial side of the triangular fibrocartilage involving the central disc with complete resolution of symptoms. It is a simple technique, which can be used to repair class 1B peripheral tears and pre-1D tears in the substance of the TFCC.
