Sagittal Band Injury and Extensor Tendon Realignment.

Orthop Clin North Am 2022 Jul 27;53(3):319-325. Epub 2022 May 27.

Department of Orthopaedic Surgery and Biomedical Engineering, University of Tennessee Health Science Center - Campbell Clinic, 1211 Union Avenue, Suite 510, Memphis, TN 38104, USA.

The sagittal bands are structurally important, aiding in the central alignment of the extensor tendons over the heads of each metacarpal. They resist the deviation of the tendon with flexion of the metacarpophalangeal (MCP) joint. Injury to the sagittal band can cause the extensor tendon to lose its alignment leading to pain, tendon subluxation, or dislocation. Read More

The Syringe External Fixator: Short- and Medium-Term Functional Outcomes From This Inexpensive and Customizable Treatment for Comminuted Intra-Articular Fractures of the Hand.

J Hand Surg Am 2021 Oct 1. Epub 2021 Oct 1.

The Curtis National Hand Center, MedStar Union Memorial Hospital Baltimore, MD. Electronic address:

Purpose: Comminuted intra-articular fractures and fracture dislocations of the metacarpophalangeal (MCP) and interphalangeal joints are challenging. Dynamic external fixation, permitting early joint motion while still minimizing forces across the healing joint, can result in acceptable postoperative active range of motion (AROM). However, some fractures are not initially stable enough for early dynamic motion; further, many available dynamic external fixation systems are costly and cumbersome. Read More

A novel technique of pulley creation for additional sagittal band reconstruction.

Hand Surg Rehabil 2021 10 10;40(5):568-571. Epub 2021 Sep 10.

Department of Orthopedic Surgery, Chonnam National University Hospital, Chonnam National University School of Medicine, 42 Jebong-ro, Dong-gu, Gwangju 61469, South Korea. Electronic address:

Because surgical treatment of chronic extensor tendon dislocation with sagittal band injury is complex and often requires donor grafts, we suggest a new technique: pulley creation for additional sagittal band reconstruction. A 76-year-old man diagnosed with chronic extensor tendon dislocation with radial sagittal band injury was treated by resecting the distended portion of the radial sagittal band, followed by plication. Using the remnant tissue obtained after resection, additional sagittal band reconstruction was performed using two mini soft suture anchors in the form of a pulley surrounding the extensor tendon.

Snapping Extensor Pollicis Longus Tendon Subluxation Secondary to Trapeziometacarpal Instability: Case Report and Technique.

JBJS Case Connect 2021 03 25;11(1). Epub 2021 Mar 25.

Department of Orthopaedic and Plastic Surgery, Wright State University Boonshoft School of Medicine, Dayton, Ohio.

Case: A 20-year-old woman presented with painful, snapping extensor pollicis longus (EPL) tendon subluxation and trapeziometacarpal (TMC) joint instability. Hemi-extensor carpi radialis longus (ECRL) tendon autograft stabilized the TMC joint, reconstructing the 1-2 intermetacarpal ligament. The subluxed EPL tendon was centralized over the dorsal first metacarpal by tightening the metacarpophalangeal radial sagittal band and creating a dorsal first metacarpal "neosheath" pulley using ECRL graft remnant.

Factors Related to Failure of Conservative Treatment in Volar Plate Avulsion Fractures of the Proximal Interphalangeal Joint.

Clin Orthop Surg 2020 Sep 3;12(3):379-385. Epub 2020 Jun 3.

Department of Orthopaedic Surgery, National Medical Center, Seoul, Korea.

Backgroud: Volar plate avulsion fractures of the proximal interphalangeal (PIP) joint are a common hand injury and have been treated conservatively with favorable results. We assumed that conservative treatment of volar plate avulsion fractures of the PIP joint would be unsuccessful if the fracture fragment, even if small, was much displaced or rotated and that delayed excision of the avulsion fractures would result in good outcomes. We report clinical and radiological outcomes of conservative treatment of volar plate avulsion fractures of the PIP joint and risk factors for failure of conservative treatment. Read More

Complex Irreducible Dorsal Dislocation of Thumb Interphalangeal Joint: Controversies and Consensus in Management.

Leon Alexander

J Hand Surg Asian Pac Vol 2020 Sep;25(3):378-383

Department of Plastic & Reconstructive Surgery, Universal Hospital, Abu Dhabi, UAE.

Dislocations of thumb interphalangeal (IP) joint are rare injuries due to inherent stability of the joint. This report presents a case of complex irreducible dorsal IP joint dislocation of thumb due to interposition of four structures - volar plate, sesamoid bone, flexor pollicis longus tendon and digital nerve which is perhaps the only case reported so far in literature where more than three structures have been implicated for this joint irreducibility. The author presents a comparative review of similar case reports previously reported in literature listing the controversies in management and forming a broad consensus in the management of these difficult injuries.

New approach to second metacarpophalangeal joint dislocation management: the SKY needling technique.

Eur J Orthop Surg Traumatol 2021 Jan 11;31(1):189-192. Epub 2020 Jul 11.

Department of Orthopedics, AIIMS, Raipur, India.

Second metacarpophalangeal dislocation is a rare entity, wherein correct diagnosis can be achieved by careful and experienced clinical examination that must be followed by radiological examination. This mostly requires open reduction either by dorsal or volar approach. Open reduction by volar approach is being used most widely but has more incidence of postoperative loss of sensation at volar aspect of finger due to neurovascular injury (digital nerve and vessel) and also required more extensive dissection.
