Summary
Latissimus dorsi transfer (LDT) following reverse shoulder arthroplasty (RSA) effectively restores shoulder motion. Implant design and concomitant teres major transfer (TMT) do not significantly impact outcomes, with a complication rate similar to standard RSA.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Rehabilitative Medicine
Background:
- Reverse shoulder arthroplasty (RSA) aims to restore shoulder function.
- Latissimus dorsi transfer (LDT) is a surgical technique explored to improve motion after RSA, particularly for combined loss of forward elevation (FE) and external rotation (ER).
- This review evaluates the efficacy and safety of LDT in conjunction with RSA.
Approach:
- A systematic review adhering to PRISMA guidelines was conducted.
- Searched PubMed/MEDLINE, Embase, Web of Science, and Cochrane databases for studies on LDT with RSA.
- Primary outcomes included ER, FE, Constant score, and complication incidence; secondary outcomes analyzed implant design and concomitant teres major transfer (TMT).
Key Points:
- Nineteen studies involving 258 RSAs were analyzed.
- Significant improvements in mean ER (preop -12° to postop 25°) and FE (preop 72° to postop 141°) were observed.
- The complication rate was 14.1%, with no significant differences in outcomes based on implant design or TMT.
Conclusions:
- RSA with LDT is a reliable procedure for restoring shoulder motion.
- Complication rates are comparable to standard RSA procedures.
- Clinical outcomes appear unaffected by implant positioning (medialized vs. lateralized) or the addition of TMT.

01:23Muscles of the Shoulder
4.0K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...
