Introduction
The proximal part of the humerus anatomically consists of the humeral head, the greater tuberosity, the lesser tuberosity and the shaft of the humerus [
1]. This is articulated with the scapula to form the glenohumeral joint, which allows the largest range of shoulder movement. Generally, a fracture of the proximal humerus indicates that the fracture has occurred above the proximal third of the humerus which includes the humeral head, the greater tuberosity, the lesser tuberosity and the shaft the of upper humerus [
2]. These fractures account for approximately 6% of all fractures in the body [
3] and are the third most common fracture in elderly people following wrist and hip fractures [
4]. Almost 80% of proximal humeral fractures are non-displaced fractures, which enable full recovery of fracture and joint function with conservative treatment [
5]. In cases such as displaced fractures and comminuted fractures, surgical treatment is considered, but there is controversy over whether the outcome is better than conservative treatment. The types of surgical treatments for proximal humeral fractures include fixation with percutaneous techniques, intramedullary nails, locking plates and arthroplasty [
6]. Rehabilitation for proximal humeral fractures after surgery is focused on recovery of the fracture, improvement of the range of motion (ROM) in the shoulder, regaining joint function through muscle strengthening and ultimately improving quality of life of the patient. There has only been 1 report where Korean traditional medicine has been used for treatment of a proximal humeral fracture, although it was not used postoperatively [
7].
In this current case study, we report the effects of using Korean traditional medicine to improve the patient’s ROM and joint function following traumatic proximal humeral fracture surgery.
Discussion
In this case report, the patient with postoperative pain for traumatic proximal humerus fracture was treated with Korean traditional medicine including acupuncture, cupping therapy and herbal medicine.
Samultang decoction is usually prescribed for the purpose of hematopoietic actions in Korean traditional medicine, in addition, a recent study demonstrated anti-inflammatory action [
11]. Gami-samultang decoction was prescribed in order to reduce swelling and inflammation in the surgical area. In addition, other medicine was used to treat the loss of blood stasis and to accelerate fracture recovery.
Acupuncture points were selected to avoid the surgical area to prevent infection. ST, GB and KI meridians were selected as remote acupuncture points, because the patient complained of pain all over her left shoulder and had limited ROM in all directions. Since the patient complained of severe pain when she abducted her shoulder, ST36 and ST37 were strongly stimulated. KI3 was also stimulated since the patient’s surgical area was at the front of her left shoulder. As a result of treatment, the NRS score decreased from 7 to 3 (
Fig. 5), the shoulder pain and disability index score decreased 93 to 25.9 (
Fig. 6).
The ROM was measured after the 21
st day of hospitalization, on the day the sling was removed. The ROM during the first measurement was flexion 65°, extension 35°, abduction 45°, adduction 25°, internal rotation 55°, and external rotation 20°. The ROM increased by the discharge date with the degree of flexion at 120°, extension 45°, abduction 105°, adduction 30°, internal rotation 55°, and external rotation 35° (
Fig. 7). The ratio of patient’s ROM compared to normal ROM showed an increase by flexion of 30%, extension 22%, abduction 33%, adduction 11%, internal rotation 0%, and external rotation 27%, increasing by 21% on average (
Table 1).
In the Neer classification [
12], the fracture type of the patient is a 3-part fracture of the proximal humeral fracture. Orthopedic studies of the 3-part fracture of the proximal humeral fracture, focused only on the outcome of conservative treatment and surgical treatment, so there is difficulty in comparing the general progress after surgery.
According to a rehabilitation program for conservative treatment 1 case recommended the removal of the sling and initiation of passive ROM exercises 3 weeks after the injury, and active ROM exercises to be initiated 6 weeks after the injury [
13]. The other case of conservative treatment, recommended initiation of passive ROM exercises immediately after the injury, but removed the sling and initiated active ROM exercises 8 weeks after injury [
14].
In the case of surgical treatment of 3 or 4 parts fracture of the proximal humeral fracture, the Hemiarthroplasty group recommended initiating passive ROM exercise immediately after surgery, but removing the sling and initiating active ROM exercise after 6 weeks and 3 days after surgery. On the other hand, in the Reverse Prosthesis group passive and active ROM exercises were initiated 1 week after surgery. It was not reported when the sling was removed in this case [
15].
In this current study, the patient initiated passive ROM exercises immediately after surgery, the sling was removed and active ROM exercises were initiated 4 weeks after surgery. Although it’s difficult to generalize treatment progress, Korean traditional medicine treatment for postoperative proximal humeral fractures showed similar treatment progress compared with conservative or surgical treatment of postoperative proximal humeral fractures.
This study is the first to date where a patient with proximal humeral fracture after surgery was treated with Korean traditional medicine. The patient had a reduced level of surgical pain, improved ROM, and ability to perform daily activities.
This case study is limited by patient numbers. In addition, there are few studies that describe the short-term progress of open reduction and internal fixation in proximal humeral fractures in orthopedics, so it was difficult to compare the effects due to Korean traditional treatment.
Further studies are required to accurately compare the treatment progress after surgery and standardize the postoperative treatment methods in Korean traditional medicine for proximal humeral fractures.
