Phase1 (1~4weeks)

Goal

Exercise

inflammatory, proliferative & repair phase.

Protected tendon healing

PROM

Scapular realignment

 

1. Passive Rom

2. short-arm traction(IR/ER)

3. assisted forward flextion

4. scapular depression & protraction

(minimal posterior RC acivity)

5. pendulum(infra/supra MVIC 15%)

Avoided end range stretch (first 6 weeks), active exe

Avoided pulley exe

Avoided elevation from 30 to 60° (more 2 tendon injury, subscapularis injury)

 

Phase1 (1~4weeks)

collagen deposition and growth factors increase, with a peak increase around 10 days after surgery

repair should not be exposed to the excessive forces inposed by active motion

Pressure at the end range (stretching) should be avoided for the first 6 weeks

PROM is progressed with caution

 

Started periscapular activation

- isolated scapular depression, retraction performed and has shown to exhibit minimal posterior RC cuff activity

 

Approximately 20~30° of scapular plane

- preventing decreased blood flow in the supraspinatus

- increasing the subacromial space

회전근개에 문제가 생겨 재봉합하는 수술

재활의 목적 > 통증완화와 가동범위 회복, 기능 회복

 

합병증 보통 1.5% ~ 2.7%로 환자들의 어깨 움직임시 뻣뻣함 호소 > 치료시 신경써야한다.

재활가이드라인

회복 초기는 조직의 회복과 염증 통증감소 수술부위의 보호가 가장 중요.

수술 직후 4~6 주까지는 팔을 고정해주는 것이 중요하며 수술 후 어깨의 뻣뻣함 줄이기 위해 적절한 ROM운동이 필요하다.

 

회복과정은 3가지 단계로 구분

1 염증기 2 회복기 3재형성기

 

Operative treatment

Retear time rate

22 patients with large or massive tears (>3cm)

- immobilization 4 week, strengthening 12 weeks

66% retears, occurred within 3 months

33% tetears, occurred after 6 months

No retears from 6 to 24 months

 

ROM gains

Type 1 : small tears (1cm, very good tissue quality)

- Full AROM 6~8 weeks

Type 2 : large tears ( <3~5cm, adequate tissue)

- Full AROM 8~12 weeks

Type 3 : large massive tears ( 3~5cm<, poor tissue, retracted tissue)

- Full AROM 12~16 weeks

 

Rotator cuff tensile strength

Ablilty to tolerate up to 100 N/mm of tensile strength

However, the tendons' endurance of compressive and shear forces is much less

Irritation and inflammation of the subacromial bursa which is rich in nerve fibers

 

Bursa

protection from shearing forces

contribute to the blood supply

healing of the rotator cuff particularly

preservation of the tissue

 

Bursectomy

- lead to rotator cuff tears or adhesions of the tendons of capsule

 

Tendon Healing Potential

Partial -thickness, small full thickness tears of the rotator cuff may heal spontaneously.

Most small tears will enlarge if not surgically repaired

Rotator cuff healing stage

염증기 > 증식기 > 재형성기

 

염증기

* Following surgical tendon-to-bone fixation

* Occurs first 7 days

* The release of histamine and bradykinin increases vascular permeability

* Inflammatory cells followed by platelets and fibroblasts migrate into the repair site

* Cellular proliferation and matrix deposition of this phase is thought to be regulated by several growth factors and initially yields primarily type 3 collagen.

 

증식기

* When next 2~3 weeks, begin to proliferate or repair

* This tissue replaces, which occurs 2 to 3 weeks after tendon ingury or repair

* Combine with capillary buds and nascent extracellular matrix to form granulation tissue.

재형성기

* During the following week(after 4weeks), this repair tissue grows stronger during the transition to the maturation phase.

* Scar tissue organizes through extracellular matrix turnover.

* The initial type 3 collagen deposition is slowly replaced by type 1

 

collagen, continuing until mature scar tissue is formed

* Remodeling repair tissue does not reach maximal tensile strength for a minimum of 12~16 weeks post repair, returned to maximal failure loads after only 26 weeks of healing.

 

Fisk factors of stiff shoulder after cuff repair

Calcific tendinitis

Adhesive capsulitis

PASTA type repair

Concomitant SLAP repair

Single tendon repair

 

Effect of immobilization

Postoperative immobilization can minimize the tension on rotator cuff repairs and may lead to improved collagen orientation and visco-elastic properties as compared to immediate postoperative exercise treatment

Immobilization of the shoulder for 4-6 weeks in a slightly abducted position may minimize tension and maximize vascularization of the repair

 

신장분사 치료

post-surgically to decrease pain, swelling, muscle spasm, and minimize the inflammatory response

authors recommend the use of a home cryotherapy device for 10-14 days after surgery

 

관절 가동술

- anterior and posterior translational glides do not significantly alter stress on repaired supraspinatus tendons with the arm in resting position.

Especially, posterior translational glides have shown to significantly increase external rotation range of motion in patients with stiff shoulders.

회전근은 어깨뼈에서 시작하여 위팔뼈 위쪽 부분에 붙는 가시위근, 가시아래근, 어깨밑근, 작은원근을 말한다. 가시위근은 팔을 벌리는 기능을 하고 가시아래근과 작은원근은 팔을 바깥으로 돌리는기능을 하며 어깨 밑근은 팔을 안쪽으로 돌리는 기능을 한다. 회전근은 팔을 움직이는 역할을 할 뿐 아니라 관절오목에 대하여 위팔뼈 머리의 안정성을 제공한다.

어깨관절은 그 자체만으로는 불안정하기 때문에 회전근은 어깨 관절의 안정성을 유지하는 데 매우 중요한 역할을 한다.

 

가시위근 : 어깨뼈의 가시위오목에서 시작하여 위팔뼈 큰결절의 윗 면에 붙는다. 어깨위신경의 지배를 받는다.

 

가시아래근 : 어깨뼈의 가시아래오목에서 시작하여 위팔뼈 큰결절의 중간면에 닿는다. 어깨위신경의 지배를 받는다.

 

작은원근 : 어깨뼈 가쪽모서리 중간에서 시작하여 위팔뼈 큰결절 아랫면에 닿는다. 겨드랑 신경의 지배를 받는다.

 

어깨밑근 : 어깨뼈의 밑오목에서 시작하여 위팔뼈 작은결절에 붙는다. 어깨밑신경의 지배를 받는다.

Glenohumeral Joint 의 정의

 

Glenohumeral Joint

 

GH joint는 위팔뼈머리의 큰 볼록면과 관절오목의 얄은 오목면 사이에 형성된 관절이다. 이 관절 은 어깨의 큰 가동범위를 만들어내기 위해 어깨뼈의 움직임과 연합 하여 작용한다.

 

해부학적 위치에서 관절오목의 관절면은 어깨면쪽 방향인 앞 가쪽으로 향해 있다. 대부분의 사람에 있어관절오목은 약간 위쪽으로 돌림되어 있다.

해부학적 위치에서위팔뼈머리는 안쪽과 위쪽으로 향하고 있으며뒤굽음(retroversion)의 특성에 의해 뒤쪽으로도향하고 있다. 이러한 방향에 의해 위팔뼈머리는 어깨면에 놓이게 되어관절오목 의 관절면과 바로 마주보게 된다.

 

GH joint3도의 자유도 모두에서 움직임이 일어나기 때문에 만능관절 이다. GH joint에서의 일차적 운동은 굽힘과 폄 벌림과 모음, 그리고 안쪽 돌림과 가쪽돌림이다.
