Orthosis and Foot Structure Affect the Fifth Metatarsal Principal Strains During Simulated Level Walking.

Am J Sports Med 2022 05 18;50(6):1659-1667. Epub 2022 Mar 18.

Hospital for Special Surgery, New York, New York, USA.

Background: Fractures of the proximal fifth metatarsal bone are common injuries in elite athletes and are associated with high rates of delayed union and nonunion. Structural features of the foot may increase fracture risk in some individuals, emphasizing the need for intervention strategies to prevent fracture. Although orthotic devices have shown promise in reducing fractures of the fifth metatarsal bone, the effect of orthosis on fifth metatarsal strains is not well understood. Read More

Predictive factors for the bone union disorder of intramedullary screw fixation in proximal fifth metatarsal bone fractures.

Arch Orthop Trauma Surg 2022 Mar 2. Epub 2022 Mar 2.

Department of Sports Orthopedics Surgery, Kanto Rosai Hospital, 1-1, Kizuki Sumiyoshi-cho, Nakahara-ku, Kawasaki, Kanagawa, 211-8510, Japan.

Less Invasive Surgery With Autologous Bone Grafting for Proximal Fifth Metatarsal Diaphyseal Stress Fractures.

J Foot Ankle Surg 2022 Jul-Aug;61(4):807-811. Epub 2021 Dec 7.

Department of Sports Orthopedic Surgery, Kanto Rosai Hospital, Kanagawa, Japan.

Surgery with autologous bone grafting for proximal fifth metatarsal diaphyseal stress fracture has a potential to decrease nonunion, but it is not performed widely as the primary surgery because of donor-site morbidity. We have devised and performed a less invasive surgical procedure with autologous bone grafting and aimed to investigate the clinical and radiologic outcomes of this procedure. The data for 73 patients who underwent primary intramedullary screw fixation with autologous bone grafting from the fifth metatarsal base for proximal fifth metatarsal diaphyseal stress fractures were investigated retrospectively.

Radiol Case Rep 2022 Mar 9;17(3):423-426. Epub 2021 Dec 9.

Student Research Committee, Tabriz University of Medical Sciences, Tabriz, Iran.

Osteoid osteoma is a relatively common benign bone tumor that is most frequently seen on the appendicular skeleton in adolescents and young adults. Here we present the case of a 14-year-old boy presenting with a 10 month history of pain in his left foot which had been misdiagnosed as stress fracture due to its unusual clinical presentation. Magnetic resonance imaging of the left foot revealed a bone lesion with typical features of the osteoid osteoma on the distal part of the second metatarsal bone. Read More

Clinical and Biomechanical Progression after Ankle Joint Distraction in a Young Adolescent Patient with Haemophilia.

Int J Environ Res Public Health 2021 10 29;18(21). Epub 2021 Oct 29.

Musculoskeletal Rehabilitation Research Group, Department of Rehabilitation Sciences, KU Leuven, Spoorwegstraat 12, B-8200 Brugge, Belgium.

Ankle joint distraction (AJD) has been described to be a valuable joint-sparing alternative to arthrodesis or arthroplasty; however, clinical endpoints associated to this surgical intervention are lacking. The current case report describes clinical and biomechanical outcome measures of ankle joint distraction in a 14-year-old patient with severe haemophilia A. Because of persistent and incapacitating pain and the poor response to conservative and invasive treatment options, ankle joint distraction was performed in this 14-year-old patient using an external fixator encompassing two Ilizarov full rings in the tibia and a foot ring fixed to the foot by four K-wires.

JBJS Rev 2021 10 21;9(10). Epub 2021 Oct 21.

University Center of Orthopaedics and Traumatology, University Hospital Carl Gustav Carus Dresden, Dresden, Germany.

»: Fractures of the proximal fifth metatarsal (PFMT) are one of the most common foot injuries, accounting for 61% to 78% of all foot fractures, but full consensus on their classification, diagnosis, and treatment has not yet been reached.

»: The most commonly accepted classification is that of Lawrence and Botte, who divided the location of PFMT fractures into 3 zones with respect to their healing potential.

»: Avulsion fractures of the tuberosity of the base (zone 1) generally heal well, and nonoperative treatment is commonly recommended. Read More

J Am Acad Orthop Surg 2021 Jun;29(12):507-517

From the Mayo Clinic Arizona, Phoenix, AZ (Patel, Christopher), Chilton Medical Center, Pompton Plains, NJ (Hubbard), and the Hospital for Special Surgery (O'Malley), New York, NY.

Stress fractures of the fifth metatarsal (zones 2 and 3) remain a challenging clinical problem. It has been well established that nonsurgical treatment has unacceptably high nonunion and refracture rates. Surgical fixation remains the treatment of choice in the athletic cohort, and intramedullary screw fixation with a solid screw has been established as the most predictable means of achieving a successful outcome.
