“…They also indicated that tension on the pisohamate ligament causes an avulsion fracture of the hamate hook, and tension on the pisometacarpal ligament produces volar dislocation of the fifth CMC joint ( Figure 10). Jackson et al also reported a hamate hook fracture in an individual participating in clay shooting and suggested that the injury was caused by the avulsion force from the pisohamate ligament [6]. Our case is similar to the injury described by Garcia-Elias et al but was accompanied by an additional fourth CMC joint dislocation and avulsion fracture between the base of the fourth and fifth metacarpal.…”

We report a case of volar fourth and fifth carpometacarpal (CMC) joint dislocation complicated by a hamate hook fracture. The CMC joint was reduced in a closed fashion and temporally fixed with Kirschner wires. Using intraoperative computed tomography, the displaced fracture of the hamate hook was reduced by open reduction and internal fixation and fixed with a screw. We suggest that this rare injury was caused by the over contraction of the flexor carpi ulnaris and avulsion force from the ligamentous structure around the pisiform, hamate, and metacarpal bones.

“…The diagnosis of this kind of injury is often missed or delayed because the image of hamate hook is usually shielded in routine anteroposterior (AP) and lateral radiographs. If the diagnosis is missed, some severe complications such as ulnar nerve irritation and flexor tendon rupture tend to ensue [3][4][5] . So early diagnosis and proper treatments are of great importance.…”

To explore the clinical classification of hamate hook fracture and the treatment strategy for different type of fractures, 12 patients who suffered from hamate hook fractures were followed up retrospectively. According to the fracture sites and the prognosis, we classified the hamate hook fractures into 3 types. Type I referred to an avulsion fracture at the tip of hamate hook, type II was a fracture in the middle part of hamate hook, and type III represented a fracture at the base of hamate hook. By the classification, in our series, only 1 fell into type I, 7 type II, and 4 type III. The results were evaluated with respect to the functional recovery, recovery time and the association among the clinical classification, pre-operative complications and treatment results. The average follow-up time of this group was 8.4±3.9 months. Two cases were found to have fracture non-union and both of them were type II fractures. Six patients had complications before operation. Five cases were type II fractures and 1 case type III fracture. All the patients were satisfied with the results at the time of the last follow-up. Their pain scale and grip strength improved significantly after treatment. All the pre-operative complications were relieved. The recovery time of hamate hook excision was significantly shorter than that of the other two treatments. The incidences of both pre-operative complications and non-union in type II fractures were higher than those in type I and type III fractures. It was concluded that, generally, the treatment effects with hamate hook fracture are quite good. The complication incidence and prognosis of the fracture are closely related to the clinical classification. Early intervention is critical for type II fractures.

“…One athlete was additionally treated with a circular wrist tape after he restarted training. Recovery under conservative therapy was 8.2 Ϯ 1.5 (6)(7)(8)(9)(10)(11)(12) weeks in duration, and the final outcome (full recovery of preinjury climbing level) was satisfying in all athletes. Furthermore, 1 athlete was treated with steroid injection into the carpal tunnel; he was free of symptoms within 12 weeks.…”

“…All patients who underwent surgery were free of symptoms after 14.0 Ϯ 2.8 (12)(13)(14)(15)(16)(17)(18) weeks. The overall duration of symptoms was 10.7 Ϯ 5.1 (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24) weeks in our patient collective (Table 2).…”
