“…Multiple possibilities have been described: fracture fragment pull out, osteosynthesis with Herbert screws, KWs, mini-screw or preformed low-profile plates. 5,6 Some authors recommend the excision of the fragment as an elective treatment. 1 The hamate hook acts as an insertion of the transverse carpal ligament, the pisohamate ligament and the flexor and opponens digiti minimi muscles, although several studies have not been able to show any decrease in mobility or force afterwards.…”

“…For displaced body fractures, ORIF using preformed low-profile plates or compression screws is recommended. 5,6 Fixation with KWs may be necessary if there is an associated carpometacarpal luxation. This procedure usually fixes the fourth and fifth MCs to the third MC and the capitate bone in unstable type III fracture-dislocations, according to the fracture classification proposed by Cain et al (apub Sarabia et al 3 ); leaving conservative treatment through immobilization for type IA and IB fractures.…”

“…5 The decision between conservative or surgical treatment is based on the following criteria: stability, fracture displacement and joint involvement. 1,3 The approach most frequently described in the literature is the dorsal approach, 6 because of its lower complexity and also because it allows for an extensive body exposure.…”

Hamate fractures are rare. Their treatment depends on the displacement and type of fracture. We present the case and surgical technique of a 33-year-old male patient, who is a manual worker, with a displaced fracture of the body of the hamate bone associated with dislocation of the fourth and fifth metacarpal (MC) bones. The patient was operated on with a double palmar and dorsal approach directly over the hamate and the body hook, respectively, which was performed to improve the control reduction and avoid damaging the neighboring vascular and nerve structures. The open reduction internal fixation (ORIF) was performed by inserting mini-screws in a dorsal to palmar direction. Later, the dislocations were reduced and fixed with Kirschner wires between the fourth and fifth MC bases, and between the fourth MC base and the capitate bone. The patient was discharged 2.5 months after the fracture. The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire outcome measure was 5 points at 6 months postsurgery. Palabras Clave► fractura del ganchoso ► fractura del carpo ► reducción abierta y fijación interna ► luxación carpometacarpiana ► doble abordaje dorsal y volar ResumenLas fracturas del ganchoso son poco frecuentes y el tratamiento depende del desplazamiento y tipo de fractura. Se describe la actualidad del tema, y el caso y técnica quirúrgica de un varón de 33 años, trabajador manual que sufre una fractura desplazada del cuerpo del hueso ganchoso, con luxación asociada del 4°y 5°metacarpianos. El paciente fue intervenido realizando un doble abordaje volar y dorsal directo al gancho y cuerpo del ganchoso respectivamente para mejorar el control de la reducción y evitar el daño de las estructuras vasculo-nerviosas vecinas. Se osteosintetizó con tornillo desde dorsal a volar y redujeron y fijaron las luxaciones con agujas de Kirschner entre las bases del 4°y 5°MTC; y base de 4°MTC y hueso grande. Fue dado de alta a los 2,5 meses de la fractura. El cuestionario DASH fue de 5 puntos a los 6 meses post fractura.

“…Fractures of hamate hook often fail to unite 17 , non-union causes pain and significant limitation of function and disability, 20 and in an experimental study performed on cadaveric hands, it was suggested that minimal invasive repair of isolated hamate hook fractures is feasible 21 . Watson et al reported that there was loss of the power grip in ulnar deviation secondary to the loss of pulley effect of the hook on flexor tendons after excision of the hamate hook, and to restore the pulley effect of the hook, they recommended bone grafting for hamate hook nonunion 10 .…”

“…Scheufler et al from their study on fractured hook of hamate, recommended surgical treatment since they observed that the clinical outcome of patients, which were treated conservatively by lower arm splinting, was disappointing. They reported the surgical intervention by either screw fixation or excision, led to elimination of symptoms20 and in an experimental study performed on cadaveric hands, it was suggested that minimal invasive repair of isolated hamate hook fractures is feasible21 . Watson et al reported that there was loss of the power grip in ulnar deviation secondary to the loss of pulley effect of the hook on flexor tendons after excision of the hamate hook, and to restore the pulley effect of the hook, they recommended bone grafting for hamate hook nonunion 10 .…”

Objective: The first objective of this study was to find out the weakest part of the hook of the hamate, the second objective was to find out the vascular pattern of the weakest part. Materials and Methods: We used 55 dry bones from the Department of Anatomy, Manipal University. Bones were from adult cadavers of South Indian origin. Among 55 bones, 27 were from the right side and 28 from the left side. We measured morphometric parameters using a Metal Casing Electronic Digital Caliper, resolution 10μm. A magnifying lens (magnifying power 10x) was used to visualize the vascular foramina. Results: The differences between the right and the left hamate hooks were not statistically significant for any of the variables. (P>0.05). All hamate hooks had vascular foramina at their bases. In 17 (30%) bones, no vascular foramina were seen at the tip of the bone. Only four hamate hooks had vascular foramina at the bend. Conclusion: From the present study, we hypothesize that the bend of the hamate hook could be its weakest part, and since most of the hamate hooks lack vascular foramina at the bend, this site could be more prone to avascular necrosis. The study also aids to establish data on the hamate hook in a South Indian population.

Araçlar ve Yöntemler: Çalışmamızı Anatomi Bölümü, Manipal Üniversitesi'nden elde ettiğimiz 55 adet el kemiği üzerinde yaptık. Kemikler Güney Hindistan orijinli yetişkin kadavralara aitti. 55 kemiğin 27'si sağ, 28'i ise sol tarafa aitti. Ölçümlerimizde birim aralığı 10μm olan Elektronik Digital Kumpas kullandık. Vaskular foramen'leri görebilmek için x10 büyütmeli lens kullandık. Bulgular: Ölçüm yaptığımız tüm parametrelerde sağ ve sol hamatum kemikciğinin hamulus'ları arasında istatistiksel olarak anlamlı bir fark bulmadık (P>0,05). Hamatum kemikciğinin hamulus'larının hepsinde vaskular foramen'ler hamulus'un tabanında yer almaktaydı. 17 vakada (%30) hamulus'un uç kısmında vaskular foramen'lere rastlanmadı. Sadece 4 hamatum kemikciğinin hamulus'unda vaskular foramen'ler hamulus'un kıvrımındaydı. Sonuçlar: Hamatum kemikciğinin hamulus'larının çoğunda kıvrım yerlerinde vaskular foramen'lere rastlanmadığı için , bu bölge avaskuler nekrozlara daha yatkındır. Bu da bize hamatum kemikciği'nin en zayıf kısmının kıvrım yeri olduğunun hipotezini sunmaktadır.

Minimal Invasive Fixation of Hamate Hook Fractures Through a Dorsal Percutaneous Approach Using a Mini Compression Screw: An Experimental Feasibility Study

Abstract: Minimal invasive repair of isolated hamate hook fractures through a dorsal percutaneous approach is feasible. The special properties of the cannulated mini compression screw allow optimal screw positioning and stable fixation without risk of diplacement or disruption of the hook fragment.
