The role of bipolar radial head prostheses (RHP) in elbow fracture-dislocation is controversial, with some reports of poorer stabilization than with monopolar designs. The aim of the present study ...was to compare mono- versus bi-polar RHPs in elbow fracture-dislocation. The study hypothesis was that mono- and bi-polar RHPs do not differ in clinical and radiological results, complications or revision rates.
A single-center retrospective study included 58 patients, with a mean age of 55 years (range, 21–84 years). All received RHP for elbow dislocation with association: terrible triad, Monteggia fracture-dislocation, transolecranal dislocation or divergent dislocation. Two groups were compared: Mono-RHP, with monopolar prosthesis (n=40), and Bi-RHP, with bipolar prosthesis (n=18). All patients underwent clinical and radiological examination at last follow-up.
Mean follow-up was 42.7 months (range, 12–131 months). There were no significant (p>0.05) inter-group differences in range of motion or Mayo Elbow Performance Score. Mono- versus bi-polar design did not correlate with onset of complications (p=0.89), surgical revision (p=0.71), persistent or recurrent instability (p=0.59), or ulnohumeral (p=0.62) or capitulum (p=0.159) osteoarthritis at last follow-up.
No differences were found between mono- and bi-polar RHPs in the treatment of elbow fracture-dislocation. Clinical and radiographic results were similar, as were complications and revision rates. The literature is inconclusive, reporting contradictory conclusions. We see no contraindications to bipolar RHPs in elbow dislocation with association, notably terrible triad injury.
III, Retrospective case-control study.
Introduction
The medial head of the triceps brachii flap is already described as a local muscular or as a free flap. It allows coverage of defects of the posterior cubital region. The aim of this ...study was to describe the vascular anatomy of the musculocutaneous medial triceps brachii pedicled flap.
Methods
Eleven fresh–frozen upper limbs (6 come from women and 5 from men) were proximally injected with Indian ink agar solution. The medial head of the triceps brachii muscle was dissected and the superior ulnar collateral artery (SUCA) was isolated with its collaterals. The collateral arteries were dissected to determine whether there were septocutaneous or musculocutaneous arteries for vascularization of the skin in front of the medial head. Lengths of those collaterals arteries were measured.
Results
The average number of collaterals arteries from the SUCA supplying the medial head of the triceps brachii is 4.5 (from 3 to 6 arteries). Among these collaterals’ arteries, there are one average 1.5 (0.6–4.5) septocutaneous arteries and 3 (1–4.8) musculocutaneous arteries.
Discussion and conclusion
A musculocutaneous flap with the medial head of the triceps brachii muscle can be described with the muscle. The SUCA gives perforator arteries musculocutaneous and septocutaneous for the vascularization of the triceps brachii medial head. The use of local pedicled flap with similar tissue maximizes healing with a minimal morbidity of the donor site. This study demonstrated the feasibility of the medial head triceps brachii musculocutaneous flap to cover defect of the posterior aspect of the elbow.
Background:
Considering the long head of biceps (LHB) management, important cultural differences exist among the surgeons around the world, especially when repairing small isolated distal ...supraspinatus tears under arthroscopy. In the perspective of an international survey to analyze our practice regarding biceps management in small rotator cuff tears, the aim is to collect all the possible LHB abnormalities according to literature review, before considering that the LHB could be normal or pathologic.
Indications:
The SFA (Société Francophone d’Arthroscopie) behind its research biceps group summarized these abnormalities in a description analysis called the “biceps box” concept, which was validated with a strong inter-rater reliability. The aim is to present the description analysis using a common language with short video records for each abnormality described to reproduce “intraoperatively” the different possible scenarios the surgeon has to encounter during arthroscopic evaluation.
Technique Description:
The description of the “biceps box” concept classifies lesions of the LHB, with so-called intrinsic lesions, for which the LHB should be considered pathological: partial rupture or delamination, fissuring, lateral or medial instability or subluxation, hypertrophy with an hourglass figure; and so-called extrinsic lesions, for which the LHB should be considered healthy: damage to the pulley without bicipital instability, exposure of the articular portion of the biceps by rupture of the supraspinatus tendon, inflammation of the superficial surface of the tendon, presence of type 1 or 2 superior labral anterior to posterior (SLAP) lesions, or a chondral print.
Results:
We present the 10 possible scenarios with video records according to our description analysis.
Discussion/Conclusion:
The LHB could be considered as a pain generator in certain situations which are still not completely clear. The indication of biceps tenotomy or tenodesis depends on the interpretation of the surgeon of these abnormalities as a pathologic or a normal condition. The next step is to use these videos in an international survey to assess cultural differences regarding the management and eventually find a consensus regarding treatment options for each abnormality.

Graphical Abstract
This is a visual representation of the abstract.
Onset of radial neck osteolysis (RNO) has been reported after radial head replacement (RHR), but data are sparse regarding impact and risk factors. We therefore conducted a retrospective study, 1) to ...quantify RNO after RHR, 2) to assess clinical and radiological impact, and 3) to identify risk factors.
RNO prevalence is high, but functional impact is limited.
A single-center retrospective study included all patients undergoing RHR for acute radial head fracture between 2008 and 2017: 53 patients, with a mean age of 53.8±15.7 years range, 21–85 years. At a minimum 2 years’ follow-up, patients were assessed clinically on joint range of motion and Mayo Elbow Performance Score (MEPS) and radiologically on standard radiographs. Associations between RNO and various parameters were assessed.
At a mean 46.7±19.8 months’ follow-up range, 24–84 months, RNO was found in 54.7% of cases (29/53), with mean 4.0 ±2.8mm distal extension range, 1.2–13.4mm, corresponding to 13.4±7.3% of stem height range, 2.7–27.7%.
RNO at last follow-up was not significantly associated with reduced flexion-extension (121.9° versus 114.0°; p=0.11), pronation-supination (152.6° versus 138.3°; p=0.25) or MEPS (84.7 versus 84.8; p=0.97), or with higher rates of postoperative complications (11/29 (37.9%) versus 7/24 (29.2%); p=0.782) or surgical revision (11/29 (37.9%) versus 10/24 (41.7%); p=0.503).
RNO was significantly associated with cementless fixation (19/29 (65.5%) versus 7/24 (29.2%); p=0.01), unipolar prosthesis (21/29 (72.4%) versus 7/24 (29.2%); p=0.002), high filling-ratio, whether proximal (88% versus 77%; p=0.002), middle (84% versus 75%; p=0.007) or distal (69% versus 59%; p=0.032), and shorter radial stem (33.2mm versus 46.3mm; p=0.011). No demographic parameters showed significant association with RNO at last follow-up.
RNO was frequent after RHR, but without clinical or radiological impact in the present series. The risk factors identified here argue for involvement of stress shielding.
IV, cohort study.
We sought to assess if the medullary diameter to cortical width ratio (MD:CW), canal flair index (CFI), and canal fill (CF) of the proximal radius were associated with the presence of stress ...shielding (SS) after a MoPyC radial head arthroplasty.
We conducted a retrospective, international, multicenter (4 centers) study. A total of 100 radial head arthroplasties in 64 women and 36 men with a mean age of 58.40 years ± 14.90 (range, 25.00-91.00) were included. Radiographic measurements, including MD:CW, CFI, CF, and postoperative SS were captured at a mean follow-up of 3.9 years ± 2.8 (range, 0.5-11).
SS was identified in 60 patients. Mean preoperative MD:CW, CFI, and CF were 0.55 ± 0.09, 1.05 ± 0.18, and 0.79 ± 0.11, respectively. The presence of SS was significantly associated with MD:CW (adjusted odds ratio = 13.66; P = .001), and expansion of the stem (adjusted odds ratio = 3.78; P = .001). The amount of the SS was significantly correlated with expansion of the stem (aβ 4.58; P < .001).
Our study found that MD:CW was an independent risk factor of SS after MoPyc radial head arthroplasty. Autoexpansion of the MoPyc stem significantly increased the risk of SS and its extent. Further studies involving multiple implants designs are needed to confirm the preliminary observations presented in the current study.
Terrible triad (TT) of the elbow almost always requires surgery to prevent progression to chronic instability and more or less inevitable osteoarthritis. Progression toward osteoarthritis after ...well-conducted surgery and associated risk factors have been little reported. We performed a retrospective study: (1) to assess rates of post-traumatic elbow osteoarthritis after surgical treatment of TT; (2) to assess functional impact; and (3) to identify prognostic factors.
Prevalence of osteoarthritis after surgical treatment of TT is high, impairing functional results.
A single-center retrospective study included 53 patients, with a mean age of 50±17.8 years (range, 21–84 years), undergoing surgery for acute TT in our department. All received clinical examination with ranges of motion and Mayo Elbow Performance Index (MEPI) and radiographic assessment at a minimum 1 year's follow-up. Osteoarthritis at last follow-up was assessed on elbow X-ray in the humero-ulnar and radio-condylar compartments on the Broberg–Morrey classification. Functional impact on range of motion and MEPI and prognostic factors were assessed on Student test or ANOVA and Chi2 or Fisher test.
Prevalence of Broberg–Morrey grade 2 or 3 osteoarthritis was 45.3% (24/53) in the humero-ulnar compartment and 50% (25/50) in the radio-condylar compartment. Humero-ulnar osteoarthritis impaired MEPI (76.3 points with versus 88.4 points without; p=0.003), flexion-extension (102.3° versus 115.2°; p=0.043) and pronation-supination (138.8° versus 159.3°; p=0.006). Radio-condylar osteoarthritis had no significant impact on MEPI (81.4 points with and 84.4 points without; p=0.47), flexion-extension (104.8° and 113°; p=0.23) or pronation-supination (141.8° and 156.4°; p=0.2). Humero-ulnar osteoarthritis at last follow-up was associated with dislocation or subluxation on immediate postoperative lateral view (45.8% with versus 10.3% without; p=0.004) and at last follow-up (20.8% versus 3.4%; p=0.047) and with postoperative complications (54.2% and 27.6%; p=0.049). Radio-condylar osteoarthritis at last follow-up was associated with radial head replacement rather than internal fixation (respectively, 92% and 48%; p=0.0007) and excessively high radial head implant positioning (47.8% versus 0%; p=0.023).
Prevalence of traumatic osteoarthritis after TT surgery was high, at 45.3% in the humero-ulnar compartment and 50% in the radio-condylar compartment, with clinical impact in humero-ulnar involvement.
IV; cohort study without control group.
After rotator cuff repair (RCR), return to work and return to sports is affected by various psychosocial factors. The role of one of these factors – mood and anxiety disorders (MAD) – is still not ...clear. The primary objective of this study was to determine the influence of prior MAD on the return to work and return to sports after RCR. Our hypothesis was that patients with a history of MAD would take longer to return to work and to sports after RCR, and the rate of return would be lower, than for patients without MAD.
This was a retrospective single-center study of patients who underwent arthroscopic RCR (distal supraspinatus tear). Patients who were employed and those who participated in sports before the surgery were included in the “working” and “sports” groups, respectively. The primary outcomes were the time to return to work and return to sports after surgery. The secondary outcomes were the ratio of patients returning to work and to sports at 3, 6 and 12 months; rate of return to same level of sports; need to change or stop working or sports. The effects of prior MAD on these various outcomes were determined using Bayesian multivariate analysis.
The “working” group consisted of 158 patients (of which 16.5% had MAD) and the “sports” group consisted of 118 patients (of which 17.8% had MAD). In those with a history of MAD, return to work was 21±11 weeks later and the return to sports was 17±8 weeks later than in those without MAD. There was a 98% probability that return to work or return to sports was delayed by at least 4 weeks in patients with history of MAD. The likelihood that patients with prior MAD who undergo RCR will completely abandon their sport was 2.8 times higher (OR=2.8 1; 7.8).
We found a negative influence of prior MAD on the return to work and return to sports after RCR.
III; retrospective case-control study.
Sugaya et al described a classification system to assess postoperative rotator cuff tendon healing. Although Sugaya I and II tendons can be considered as healed and Sugaya type IV and V can be ...considered as retorn, the exact status of Sugaya III tendons remains unclear. The objective of this study was to evaluate the impact of Sugaya III tendons on postoperative functional scores in a population of patients undergoing revision rotator cuff repair.
We retrospectively studied the records of all patients who underwent revision rotator cuff repair in one of 12 different institutions between July 2001 and December 2020. A total of 203 shoulders were included (59% males, mean age: 51 ± 8 years old, mean follow-up 11.5 years range: 2-28.8 yr). Fifty-four patients (61% males, mean age 52 ± 6 years old, mean follow-up 14.1 years range: 10.4-28.8 yr) had a follow-up ≥10 years (mean 14.1 years range: 10.4-28.8 yr) and were included in a long-term follow-up subgroup analysis. Structural integrity of the repaired tendon was evaluated on magnetic resonance imaging at last follow-up. Functional scores, acromiohumeral index (AHI), and progression of fatty infiltration and of osteoarthritis were compared according to Sugaya type.
Mean Constant score and mean strength were significantly higher in Sugaya I and II tendons than in Sugaya III (P = .021 and .003) and Sugaya IV and V tendons (P = .07 and .038), but did not differ between Sugaya III and Sugaya IV and V tendons. Mean Subjective Shoulder Value, pain, AHI were significantly higher and fatty infiltration and progression in the Hamada classification were significantly lower in Sugaya I and II tendons and in Sugaya III than in Sugaya IV and V tendons (P < .05), but did not differ between Sugaya I and II and Sugaya III tendons. Similar characteristics could also be observed in the long-term follow-up subgroup.
Sugaya III tendons after revision rotator cuff repair do not allow restoration of strength thereby impacting the Constant score. However, there seems to be a protective effect of Sugaya III tendons with regard to pain, progression of proximal migration of the humeral head, osteoarthritis, and fatty infiltration, which seems to last at long-term follow-up.
