“…[2][3][4][5]25 Ninety-five percent of these fractures occur in men. 11,26 In a series of 62 patients, the fracture was located at the base and proximal third of the hamate hook in 76 percent, in the mid third in 13 percent, and in the distal third in 11 percent, with 32 percent of fractures being displaced.…”

The treatment of choice in nondisplaced hook of hamate fractures is conservative, with lower arm splinting. Displaced fractures should be treated operatively, whereby excision of the fragment or open reduction and internal fixation are described. A hamulus ossis hamati fracture was verified in 14 patients (mean age, 42 years; range, 21 to 73 years) including 11 men and three women. In six patients (42.9 percent), conservative treatment was initiated immediately after trauma with a lower arm cast for 6 weeks, and eight patients (57.1 percent) were operated on primarily. In five patients (35.7 percent), the fragment was excised, and in three patients (21.4 percent), an open reduction and internal fixation was performed using a screw. In five of six patients treated conservatively, nonunion of the fracture with persisting clinical symptoms developed. All of those patients were treated operatively, whereby three patients underwent excision and two patients underwent screw fixation, which led to elimination of the symptoms. One patient was asymptomatic despite nonunion of the fracture and rejected surgery. All of the eight patients operated on primarily were asymptomatic 3 months after surgery. Therefore, the success rate of primary surgical treatment (eight of eight) was significantly higher compared with conservative treatment(one of six). Finally, all 14 patients were asymptomatic at late postoperative follow-up. The clinical outcome of patients with hook of hamate fractures treated conservatively was disappointing. Therefore, primary surgical treatment is recommended. In our patients, excision and open reduction and internal fixation led to comparable results.

“…Formula for calculating the recoil energy is E ϭ 1 ⁄ 2(Wr ⁄ 32) (Wb ϫ MV ϩ 4, 700 ϫ Wp ⁄ 7, 000 ϫ Wr) 2 Where E ϭ recoil energy in ft-lb, Wr ϭ weight of gun in pounds, Wb ϭ Weight of shot ϩ wad in grains, MV ϭ muzzle velocity of shot in ft/s, Wp ϭ weight of powder in grains. For example, for a shotgun with 10 gauge, 3.5-in length, 2.25-oz shot, muzzle velocity of 1,210 ft/s, and weight of 10.5 lb the recoil energy would be 62.9 ft-lb (Available at: www.chuckhawks.com/shotgun_recoil_table.htm).…”

“…1,2 Due to the popularity of sports involving the use of clubs, rackets, or bats, as golf, tennis, baseball, and hockey, the incidence of stress fractures of the hook appears to increase. [3][4][5][6] More careful assessment of wrist injuries and improved radiographic imaging have added to more frequent detection of this fracture. [7][8][9] Repeated microtrauma to the hook during sports is thought to be responsible for stress fractures, with golf accounting for an estimated one third of this type of injury, typically involving the nondominant hand.…”

Symptomatic nonunion frequently results after conservative treatment of hamate hook fractures, emphasizing the need of appropriate surgical strategies. A retrospective analysis of 8 patients with nonunions treated by fragment excision or open reduction and internal fixation (ORIF) at 3 centers was performed. The literature was reviewed for treatment options, as bone grafting and low-intensity pulsed ultrasound. Although fragment excision is advocated as the "gold standard" in nonunion, reports on functional results are controversial, and recent anatomic and biomechanical studies of the hook challenge this opinion. In our patients, complete relief of symptoms and comparable functional results were observed after ORIF or fragment excision. Bone grafting could supplement ORIF in selected cases. Low-intensity pulsed ultrasound may evolve as a conservative treatment option. Several alternatives to hook excision are available aiming at complete anatomic and functional recovery of hamate hook nonunion. Further experience is needed before general recommendations can be formulated.
