Treatment of Pectoralis Major Tendon Tears: A Systematic Review and Meta-analysis of Operative and Nonoperative Treatment

Tendon transfers for the management of irreparable subscapularis tears

Rotator cuff pathology is the main cause of shoulder pain and dysfunction in older adults. When a rotator cuff tear involves the subscapularis tendon, the symptoms are usually more severe and the prognosis after surgery must be guarded. Isolated subscapularis tears represent 18% of all rotator cuff tears and arthroscopic repair is a good alternative primary treatment. However, when the tendon is deemed irreparable, tendon transfers are the only option for younger or high-functioning patients. The aim of this review is to describe the indications, biomechanical principles, and outcomes which have been reported for tendon transfers, which are available for the treatment of irreparable subscapularis tears. The best tendon to be transferred remains controversial. Pectoralis major transfer was described more than 30 years ago to treat patients with failed surgery for instability of the shoulder. It has subsequently been used extensively to manage irreparable subscapularis tendon tears in many clinical settings. Although pectoralis major reproduces the position and orientation of the subscapularis in the coronal plane, its position in the axial plane - anterior to the rib cage - is clearly different and does not allow it to function as an ideal transfer. Consistent relief of pain and moderate recovery of strength and function have been reported following the use of this transfer. In an attempt to improve on these results, latissimus dorsi tendon transfer was proposed as an alternative and the technique has evolved from an open to an arthroscopic procedure. Satisfactory relief of pain and improvements in functional shoulder scores have recently been reported following its use. Both pectoralis minor and upper trapezius transfers have also been used in these patients, but the outcomes that have been reported do not support their widespread use.

Pectoralis major tendon rupture repairs using intramedullary suture anchors shows high patient-reported outcomes in military service members

BACKGROUND

In the general population, pectoralis major tendon ruptures are uncommon; however, it is a common injury in the military population. The military service members have greater physical demands than the general population. The purpose of this study is to critically assess the postoperative outcomes of pectoralis major tendon ruptures in military service members following a repair using intramedullary suture anchors.

METHODS

A retrospective chart review was performed between 2014 and 2022, identifying patients who underwent a pectoralis major rupture repair performed by the senior surgeon using intramedullary suture anchors. Records were reviewed for age, gender, mechanism of injury, chronicity, visual analog scale, and Single Assessment Numeric Evaluation (SANE) scores. Patients who had less than 1 year of follow-up were excluded from the study. During the study period, 18 patients underwent surgical repair of their torn pectoralis major, and 15 patients were followed up >1 year postoperatively. Twelve of these 15 patients (80%) were successfully contacted, and patient-reported outcomes were collected.

RESULTS

A total of 12 patients (12 male, 0 female) with a mean age of 34.5 years were identified. Average time from injury to surgery was 471.4 days. Average duration of follow-up was 3.7 years. There was a decrease in the preoperative average single repetition maximum (1RM) barbell bench press of 125.7 kg (277 lbs) to a postoperative average 1RM bench press of 101.8 kg (225 lbs) (P = .03). Mean change in average 1RM barbell bench press is a 19.04% decrease postoperatively. Postoperative SANE score was 80.8 and an American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form score of 86.9. Seven patients (58.3%) stated they were afraid to bench press at their previous weight because of fear of reinjury. None of the patients were medically discharged from the military owing to limitations from their repaired shoulder. Ten patients (83%) reported they were extremely satisfied with their shoulder function postoperatively.

CONCLUSION

Repair of the pectoralis major tendon ruptures using intramedullary suture anchors has high rates of return to duty, patient satisfaction, and patient-reported outcomes. More than half of the patients reported they were afraid to bench press at their preinjury weight because of concerns of reinjury; the decrease in postoperative strength may be a result of the patients' fear of reinjury rather than physiologic limitations.

Functional Considerations in Bilateral, Simultaneous Tendon Injuries of the Upper Extremity: A Narrative Review of Current Literature

» Bilateral, simultaneous same-tendon injuries of the upper extremity are rarely encountered, yet their unique complexity poses a substantial challenge for treating orthopaedic surgeons.» In general, extremities with more tendon retraction should be repaired acutely while contralateral injuries can be treated in a staged or simultaneous manner depending on injury morphology, location, and anticipated functional impairment.» Combinations of accelerated and conventional rehabilitation protocols can be used for individual extremities to minimize the length of functional impairment.

Reconstruction of Chronic, Retracted Pectoralis Major Tendon Tear With Achilles Tendon Allograft

Rupture of pectoralis major tendon (PMT) is an uncommon injury, but its incidence has been increasing in the past 2 decades. Although open repair of the torn tendon is the preferred choice of treatment in acute and chronic cases, this often is not possible for chronic retracted tendon injuries. While several techniques have been described for PMT reconstruction, these allografts and autografts are often smaller and less thick than the native PMT. In this study, we describe the use of the Achilles tendon allograft with unicortical suture buttons for the reconstruction of a chronic and retracted PMT. Furthermore, the advantages and disadvantages of this technique are discussed.

The 'Cruciform Test': A diagnostic tool to detect pectoralis major rupture

Introduction

Pectoralis major (PM) rupture is a severe injury that untreated can lead to a profound functional deficit. Early surgical repair can greatly improve outcomes and give a more predictable timetable for recovery, making this the goal of current treatment. Surgical intervention is also essential to return professional athletes to their previous level of competition. However, there is no single, reliable and easily reproducible test that can be used to establish the diagnosis. We describe 'The Cruciform Test'; a method of identifying PM rupture that can be used for initial diagnosis either in clinic or a pitch-side environment, or to assess restoration of normal anatomy and function post-operatively.

Methods

We studied a series of 14 patients who underwent open PM repair in order to evaluate this method of assessment.

Results

All patients had a positive test pre-operatively. 5 were formally tested at post-operative follow-up and all had a negative result.

Discussion

The Cruciform Test is a simple and reproducible diagnostic tool that has potential as a clinical indicator of both PM rupture and successful repair. It can therefore contribute to earlier diagnosis, prompt surgical intervention and facilitate return to play at the earliest opportunity.

Video Analysis of Pectoralis Major Injuries in Professional Australian Football Players

Background:

There is little evidence regarding the mechanisms of pectoralis major (PM) injury and player outcomes in Australian Football League (AFL) players.

Purposes/Hypothesis:

The study aims were to investigate (1) the mechanisms of PM muscle injury in elite AFL players via video analysis and (2) the player profile, method of management, and clinical outcomes of the PM injuries sustained. We hypothesized that the majority of PM tears would occur in outer-range PM positions (hyperextension of the glenohumeral joint).

Study Design:

Case series; Level of evidence, 4.

Methods:

We analyzed video of the precipitating event for traumatic PM injuries during AFL competition or training over a 20-year period (2002-2021). The footage was analyzed by 4 experienced assessors, and the following were evaluated: mechanism of injury, injury variables (arm position, initial contact point, visual awareness, and use of taping), player characteristics (age at the time of injury, hand dominance, and history of injury), injury profile (location and size of tear), method of management (operative vs nonoperative), patient outcomes (time to return to full senior training/match play), and complication rates.

Results:

The mean ± standard deviation age of the players was 26.5 ± 3.1 years (range, 21-32 years). Overall, 22 PM injuries were identified in the AFL injury database for a rate of 1.1 per year; 16 of these injuries had accompanying video footage. We identified 3 mechanisms for PM injury: horizontal hyperextension (62.5%), hyperflexion-abduction (25.0%), and horizontal adduction (sustained tackling; 12.5%). The most common site of the tear was the insertion point of the sternocostal head (91.0%). Twenty players (91.0%) required surgical repair, with 75% undergoing surgery within 1 week (range, 0-26 weeks). The mean return to competition for the surgical repair group was 11.1 weeks (range, 8-15 weeks). The rerupture rate was 5.0% (1 repair; <4 weeks postoperatively in 2004).

Conclusion:

PM tears in elite male AFL players were due to 1 of 3 distinct mechanisms: horizontal hyperextension, hyperflexion-abduction, and horizontal adduction (sustained tackling). Players returned to play on average 11 weeks after injury. Knowledge regarding mechanisms of injury, player profile, and return-to-sport timelines is important for appropriate medical management and provides potential areas to target for prevention of PM injuries.

Influence of Fatty Infiltration on Hip Abductor Repair Outcomes: A Systematic Review and Meta-analysis

BACKGROUND

Increasing evidence supports surgical intervention for hip abductor tears; however, the influence of fatty infiltration (FI) on outcomes after repair remains uncertain and has been addressed only in small case series.

PURPOSE

To clarify the relationship between FI and surgical outcomes for hip abductor tears.

STUDY DESIGN

Meta-analysis; Level of evidence, 4.

METHODS

A systematic review and meta-analysis was conducted according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. FI severity was assessed by Goutallier-Fuchs (G-F) grade. The relationship between FI and improvement in Harris Hip Score (HHS)/modified Harris Hip Score (mHHS) and visual analog scale (VAS) score for pain was examined with mixed-effects metaregression. Outcomes with open and endoscopic techniques were also compared.

RESULTS

A total of 4 studies (206 repairs in 201 patients) were eligible. High-grade FI was associated with significantly less improvement in HHS/mHHS than both no FI (6.761 less; 95% CI, 3.983-11.570; P = .002) and low-grade FI (7.776 less; 95% CI, 2.460-11.062; P < .001) but did not significantly influence VAS score (P > .05). Controlling for FI severity, we found no significant difference in HHS/mHHS improvement between open versus endoscopic repair (P > .05 at each level), but open repair resulted in significantly greater improvement in VAS score for every G-F grade (all P < .005).

CONCLUSION

Surgical intervention for symptomatic hip abductor tendon tears improved outcomes as reflected by change in HHS/mHHS; however, the presence of high-grade FI resulted in less improvement. FI severity did not influence VAS scores for pain. Although no differences were found between open and endoscopic repairs in terms of FI-adjusted improvement in HHS/mHHS, open repairs resulted in significantly greater pain relief at each FI level.

No Difference in Complications Between Elbow Ulnar Collateral Ligament Reconstruction With the Docking and Modified Jobe Techniques: A Systematic Review and Meta-analysis

BACKGROUND

The most commonly used techniques for elbow ulnar collateral ligament reconstruction (UCLR) are the docking and modified Jobe figure-of-8 techniques. Previous literature has suggested that UCLR with the docking technique is associated with fewer complications; however, these studies included results from the original classic Jobe technique without controlling for the effects of flexor pronator mass (FPM) detachment and routine submuscular ulnar nerve transposition (UNT).

PURPOSE/HYPOTHESIS

This study sought to compare the rates of complications and subsequent unplanned surgical procedures between the docking and figure-of-8 techniques. We hypothesized that there would be no significant difference in the rates of complications or subsequent unplanned surgical procedures between the techniques when the FPM was preserved and no routine submuscular UNT was performed.

STUDY DESIGN

Systematic review and meta-analysis; Level of evidence, 4.

METHODS

This study was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A series of mixed-effects multivariate metaregression models were implemented using the restricted maximum likelihood method. Complications and subsequent unplanned surgical procedures were modeled as Freeman-Tukey transformed incidence rates for variance stabilization, and nerve-specific complications were assessed as the Freeman-Tukey transformed proportion of cases, with back-transformation to estimate summary effects.

RESULTS

There were 19 studies eligible for qualitative analysis, consisting of 1788 cases of UCLR (303 docking, 1485 figure-of-8), 18 of which were suitable for quantitative analysis (1769 cases; 291 docking, 1478 figure-of-8). A total of 338 complications were reported (17 for docking, 321 for figure-of-8), the majority of which were nerve related. Additionally, a total of 75 subsequent unplanned surgical procedures were related to the index UCLR procedure. There was no significant difference in the rate of complications (P = .146) or proportion of cases with nerve-specific complications (P = .127) between the docking and figure-of-8 techniques when controlling for FPM preservation versus detachment with submuscular UNT. FPM detachment with submuscular UNT was independently associated with a significantly higher proportion of postoperative nerve-related complications (P = .004). There was also no significant difference in the rates of subsequent unplanned surgical procedures between the docking and figure-of-8 techniques (P = .961), although FPM detachment with routine submuscular UNT was independently associated with a significantly higher incidence of subsequent unplanned surgical procedures.

CONCLUSION

The results of this study demonstrate no significant difference in the rates of complications or subsequent unplanned surgical procedures between the figure-of-8 and docking techniques for UCLR when controlling for FPM preservation versus detachment with submuscular UNT. With modern muscle-sparing approaches and avoiding submuscular UNT, the modified Jobe technique does not differ significantly from the docking technique in terms of complication rates, proportions of cases with nerve-specific complications, or rates of subsequent unplanned surgical procedures.

Routine Capsular Closure With Hip Arthroscopic Surgery Results in Superior Outcomes: A Systematic Review and Meta-analysis

BACKGROUND

In hip arthroscopic surgery, capsulotomy is performed to improve visualization and allow instrumentation of the joint. Traditionally, the defect has been left unrepaired; however, increasing evidence suggests that this may contribute to persistent pain and iatrogenic capsular instability. Nevertheless, the clinical benefit of performing routine capsular repair remains controversial.

PURPOSE/HYPOTHESIS

We conducted a systematic review and meta-analysis to investigate the effects of routine capsular closure on patient-reported outcomes (PROs), hypothesizing that superior PROs would be observed with routine capsular closure.

STUDY DESIGN

Meta-analysis and systematic review; Level of evidence, 4.

METHODS

A systematic review and meta-analysis was conducted according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The terms "hip,""arthroscopy,""capsule,""capsular,""repair," and "closure" were used to query Ovid MEDLINE, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), CINAHL (Cumulative Index to Nursing and Allied Health Literature), SPORTDiscus, and PubMed. Articles with PROs stratified by capsular management were included. Multivariate mixed-effects metaregression models were implemented with study-level random-effects and fixed-effects moderators for capsular closure versus no repair and after controlling for surgical indication and preoperative PROs. The effect of repair on both the postoperative score and the change in scores was evaluated via the Harris Hip Score (HHS)/modified HHS (mHHS), Hip Outcome Score (HOS)-Activities of Daily Living (ADL), and HOS-Sport Specific Subscale (SSS), with a supplemental analysis of additional outcomes.

RESULTS

Of 432 initial articles, 36 were eligible for analysis, with results for 5132 hip arthroscopic procedures. The capsule was repaired in 3427 arthroscopic procedures and unrepaired in 1705. Capsular repair was associated with significantly higher postoperative HHS/mHHS (2.011; SE, 0.743 [95% CI, 0.554-3.467]; P = .007), HOS-ADL (3.635; SE, 0.873 [95% CI, 1.923-5.346]; P < .001), and HOS-SSS (4.137; SE, 1.205 [95% CI, 1.775-6.499]; P < .001) scores as well as significantly superior improvement on the HHS/mHHS (2.571; SE, 0.878 [95% CI, 0.849-4.292]; P = .003), HOS-ADL (3.315; SE, 1.131 [95% CI, 1.099-5.531]; P = .003), and HOS-SSS (3.605; SE, 1.689 [95% CI, 0.295-6.915]; P = .033).

CONCLUSION

This meta-analysis is the largest to date evaluating the effect of capsular closure on PROs and demonstrates significantly higher mean postoperative scores and significantly superior improvement with repair, while controlling for the effects of preoperative score and surgical indication. The true magnitude of the benefit of capsular repair may be clarified by large prospective randomized studies using PRO measures specifically targeted and validated for hip arthroscopic surgery/preservation.

[Rupture of the pectoralis major muscle in amateur athletes: a rare injury or often overlooked?]

INTRODUCTION

A rupture of the pectoralis major muscle is a rare injury pattern overall, but it is frequently described in athletes, particularly in weightlifting. The risk of sustaining this type of injury is present especially during the eccentric phase of muscle loading. An association between such injuries and the abuse of anabolic steroids is described in the literature, but there is no coherent evidence to support this. We report the case of a young patient with a normal habitus who suffered a humeral rupture of the pectoralis major muscle during recreational sports. There was no history of excessive weight training or use of anabolic steroids.

CASE HISTORY

This 33-year-old patient reported a sudden onset of left pectoral pain during training on the chest fly machine as well as a whip-like popping sound, followed by an immediate painful restriction of movement in the left arm. A clinical examination revealed a mild haematoma located on the left medial upper arm with localised tenderness and a discrete asymmetry of the contour of the pectoral muscles. Due to the typical medical history, we established the indication for surgical exploration although the clinical picture was rather discrete and only an incomplete rupture was seen in an MRI scan. Intraoperatively, we detected a complete rupture of the sternocostal part of the pectoralis major muscle with marked retraction and haematoma. Reinforcement and reinsertion were performed at the "footprint" using titanium anchors (2 x 5.5mm Corkscrew FT, Arthrex, Florida). The patient was able to resume his sports activities at the pre-traumatic level four months after surgery.

CONCLUSION

A rupture of the insertion of the pectoralis major muscle must also be considered in amateur athletes with a typical history. The characteristic clinical symptoms described in the literature mostly refer to competitive athletes and bodybuilders, but these injuries can also be diagnosed in amateur athletes with lower muscle mass by subtle clinical examination. Nevertheless, there is a considerable risk of underestimating the extent of the injury. In case of doubt, surgical exploration should be performed promptly in amateur athletes. Surgical refixation of the humeral rupture of the pectoralis major muscle is the gold standard and should not be reserved to high-performance athletes.

Pectoralis Major Rupture: Evaluation and Management

Pectoralis major tendon ruptures are being reported with increasing frequency and primarily occur in young, high demand, male patients. The injury results from an eccentric contracture of the muscle most commonly while performing the bench press maneuver during weight training. In the setting of both acute and chronic injury, physical examination is critical for a timely and accurate diagnosis. During physical examination, comparison with the opposite side is imperative, and findings may include swelling, ecchymosis, loss of the anterior axillary fold, and a decreased pectoralis major index. Surgical treatment of acute ruptures is superior to nonsurgical treatment and results in improved functional outcomes and high levels of return to work and sport. Repair of chronic tears is more challenging and may require reconstruction with autograft or allograft tissue. Despite advances in surgical technique, tendon rerupture, persistent pain, and wound infection remain a concern.

Routine diagnostic arthroscopy with elbow ulnar collateral ligament reconstruction does not reduce the need for future valgus extension overload-related surgeries: a systematic review and meta-analysis

BACKGROUND

Valgus extension overload syndrome (VEOS) most commonly affects overhead athletes and consists of a constellation of conditions involving the medial, posterior, and lateral elbow, with the most widely discussed being ulnar collateral ligament (UCL) injuries. Many athletes with UCL tears also have findings consistent with other VEOS conditions, though these are not consistently symptomatic. Given the high rate of concomitant pathology, many authors have recommended performing arthroscopy at the time of UCL reconstruction (UCLR) to diagnose and address concomitant VEOS pathology; however, it is not known if this practice actually leads to a reduction in subsequent surgeries for VEOS conditions following index UCLR. The purpose of this systematic review and meta-analysis was to determine if performing routine diagnostic arthroscopy (RDA) in patients undergoing UCLR was associated with a lower incidence of future VEOS-related surgery.

METHODS

This study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, with the primary outcome of interest being the likelihood of needing future surgery to address VEOS conditions with or without RDA at the time of index UCLR. The proportion and incidence rate of subsequent VEOS-related surgeries following UCLR with and without RDA were compared in mixed effects models.

RESULTS

There were 25 eligible studies from an initial 1335 systematically identified articles, with results for 2118 UCLR cases. Among these, there were a total of 94 reported VEOS-related surgeries. The proportion of subsequent VEOS-related surgeries was lower when UCLR was performed with RDA (0.40%, 95% CI 0.00%-3.51%) than without (1.16%, 95% CI 0.03%-3.25%), but the difference was not significant (P = .584). The incidence rate of VEOS-related surgeries was 0.16 (95% CI 0.00-0.95) per 100 person-years with RDA and 0.14 (95% CI 0.00-0.55) per 100 person-years without RDA (P = .942).

CONCLUSION

RDA preceding UCLR does not significantly reduce the proportion or rate of subsequent surgery for other VEOS conditions. There has been a decrease in RDA utilization with UCLR over time for athletes with torn/incompetent UCLs but otherwise no known symptomatic VEOS conditions, and this trend appears to be justified based on these findings.

Return to Work After Pectoralis Major Repair

Background:

Pectoralis major repair (PMR) is an infrequent injury that occurs during resistance training, most commonly during the eccentric phase of muscle contraction. As the incidence of weight training continues to increase, it is important to understand the outcomes after PMR.

Purpose:

To evaluate the rate and duration of return to work in patients undergoing PMR.

Study Design:

Case series; Level of evidence, 4.

Methods:

Consecutive patients undergoing PMR from 2010 to 2016 at a single institution were retrospectively reviewed at a minimum of 1 year postoperatively. Patients completed a standardized and validated work questionnaire, as well as a visual analog scale for pain, American Shoulder and Elbow Surgeons survey, Single Assessment Numerical Evaluation, and a satisfaction survey.

Results:

Of the 60 eligible patients who had a PMR, 49 (81.7%) were contacted at the final follow-up. Of the 49 patients, 46 (93.9%) had been employed within 3 years before surgery (mean ± SD age, 40.4 ± 8.2 years; follow-up, 3.9 ± 2.8 years). Of these, 45 (97.8%) returned to work by 1.6 ± 2.1 months postoperatively, and 41 (89.1%) returned to the same level of occupational intensity. Patients who held sedentary, light-, medium-, or high-intensity occupations returned to work at a rate of 100.0%, 100.0%, 83.3%, and 66.7% by 0.8 ± 1.0, 0.8 ± 1.0, 1.3 ± 2.7, and 3.3 ± 2.7 months, respectively. Five of 6 patients (83.3%) with workers’ compensation returned to their previous occupations by 5.0 ± 1.6 months, while 100% of those without workers’ compensation returned to work by 1.1 ± 1.7 months (P < .001). Overall, 44 patients (95.7%) were satisfied with the procedure, and 40 (87.0%) would have the operation again if presented the opportunity. A single patient (2.2%) required revision PMR.

Conclusion:

Approximately 98% of patients who underwent PMR returned to work by 1.6 ± 2.1 months postoperatively. Patients with higher-intensity occupations took longer to return to their preoperative levels of occupational intensity. Information regarding return to work is imperative in preoperative patient consultation to manage expectations.

Simultaneous repair of bilateral pectoralis major tendons: A case report

BACKGROUND

Injuries to the pectoralis major are infrequent, with only a few hundred cases currently recorded in the literature.

CASE SUMMARY

We report a case of a patient who sustained bilateral pectoralis major tendon ruptures. While other cases of bilateral pectoralis major tears have been reported in the literature, the operative management in this report differs. Due to delayed presentation of the patient right and left pectoralis major repairs were performed simultaneously.

CONCLUSION

Patients with delayed presentation of bilateral pectoralis major tendon ruptures can undergo simultaneous repair of both tendon with a good postoperative outcome and high patient satisfaction.

Incidence of Pectoralis Major Injuries Has Increased 40% Over the Last 22 National Football League Seasons

Purpose

To examine trends in the incidence of pectoralis major (PM) injuries over the last 22 National Football League (NFL) seasons and identify risk factors for injuries requiring operative management.

Methods

Publicly available data from the 1998-1999 through 2019-2020 NFL seasons were reviewed to identify PM injuries, demographics, injury mechanisms, and management. Injury incidence was calculated using linear regression per 10,000 athlete-exposures, while risk factors for operative management were identified through multivariate logistic regression.

Results

There were 258 PM injuries. Mean athlete age at the time of injury was 27.1 years (range: 21-37) with a mean body mass index of 32.6 (range: 24.8-43.1). Overall incidence was 0.603 per 10,000 athlete-exposures, which was found to significantly increase with time by 0.039 per athlete-exposures per year (R² = .787, P < .001). Defensive athletes accounted for 64.7% of PM injuries. Repair was performed in 48.8% of athletes, with defensive linemen (odds ratio [OR] 3.78, CI 1.42-10.60, P = .009), defensive backs (OR 12.20, CI 2.13-76.60, P = .006), linebackers (OR 8.98, CI 2.58-33.60, P < .001), more recent time of injury (OR 1.11, CI 1.05-1.17, P < .001), and shorter NFL experience (OR .77 for older athletes, CI .59-.99), P = .047) at significant risk for operative treatment.

Conclusion

A total of 258 PM injuries were identified over 22 NFL seasons, with an overall incidence of 0.603 per 10,000 athlete-exposures, which was found to increase by 0.039 injuries per 10,000 athlete-exposures per year. Repair was performed in 48.8% of athletes, with more recent time of injury, shorter NFL experience, defensive linemen, defensive backs and linebackers at significantly higher risk for operative treatment.

Pectoralis Major Tendon Tear: A Critical Analysis Review

»

Pectoralis major (PM) tendon tears are predominantly seen in young men, and the majority of tears occur as tendon avulsions involving the sternal head. Weightlifting, specifically bench-pressing, and sporting activities with eccentric overloading of the PM tendon are the 2 most common activities that result in PM injury.

»

Early surgical repair or reconstruction should be offered to younger, active patients with a complete PM tear; the majority of the patients undergoing surgical repair achieve good-to-excellent outcomes.

»

Nonsurgical treatment of a complete PM tear is an option but will result in cosmetic deformity and a deficit in adduction strength of the arm. Outcomes after nonsurgical treatment of complete PM tears are less satisfactory than those obtained after surgical treatment.

»

Currently, there is no consensus on the chronological definition of PM tears (acute versus chronic), the critical time limit for performing surgical repair, the ideal fixation device (cortical button, bone tunnel, or suture anchors), the indications for allograft use, and the ideal rehabilitation protocol after treatment of PM tears.

Performance and Survivorship of National Football League Players with Pectoralis Major Injuries

PURPOSE

The purpose of this study was to determine return-to-play (RTP), performance and career survivorship for National Football League (NFL) athletes sustaining pectoralis major (PM) injuries with comparison among grades of injury and between nonoperative and operative management.

METHODS

Publicly available data from the 1998-2020 NFL seasons were reviewed to identify athletes with PM injuries. Athlete characteristics were collected 1 season before and 2 seasons after injury. Percent of total games played in a season, player efficiency rating (PER), and Pro Football Focus (PFF) grades were compared for the preinjury season and 2 postinjury seasons. Kaplan-Meier survivorship plots were computed for RTP and postinjury career length, whereas a log-rank test was used to compare survivorship differences.

RESULTS

In total, 258 PM injuries were reported at a mean age of 27.1 ± 3.3 years. A total of 126 surgical repairs occurred in 48.8% (n = 126) of injuries, with athletes undergoing repair possessing a lower RTP rate and longer time to RTP compared to athletes treated conservatively (P < .001). Survival analysis revealed shorter career length for athletes sustaining PM tears compared to strains (P < .001), although no difference in career length was appreciated on the basis of injury management (P = .980). Defensive linemen and wide receivers had lower PER during their second postinjury seasons (P = .019 and .030, respectively), whereas defensive linemen had lower PFF grades during their second post-injury seasons (P = .044).

CONCLUSION

NFL athletes requiring PM repair may experience a lower likelihood of RTP, and longer RTP timing, likely because of higher-grade injuries. Defensive linemen and wide receivers experiencing PM injuries are at risk for diminished performance post-injury. Career length does not appear to be affected based on injury management.

Level III, cohort study.

Parachute-Induced Pectoralis Major Tears in Military Servicemembers: What Is the Functional Recovery?

Background

Although the most common injury mechanism for pectoralis major (PM) tears is an eccentric loading mechanism typically caused by bench pressing, within the military, there is a unique injury mechanism associated with airborne operations. The results of operative repair for these parachute-induced PM tears have not been previously reported.

Purpose/Hypothesis

To assess the functional outcomes in military servicemembers undergoing operative repair of parachute-induced PM tears. We hypothesized that functional recovery would be impaired with delayed surgical intervention.

Study Design

Cohort study; Level of evidence, 3.

Methods

Included were active duty military servicemembers who underwent operative repair for PM tears caused by a parachute-induced mechanism. Charts were reviewed to identify characteristic, injury, and surgical variables. Patients completed the functional outcome assessment with the Disabilities of the Arm, Shoulder and Hand (DASH) and the American Shoulder and Elbow Surgeons (ASES) questionnaires. Outcomes were compared between patients treated within 6 weeks of injury and those treated beyond 6 weeks.

Results

Of the 68 identified PM tears, 25 were the result of parachute-induced mechanisms. A total of 13 patients consented and completed the functional outcome assessment. The mean patient age was 30.6 ± 6.4 years, and the mean follow-up period was 5.46 ± 1.26 years. Ten patients underwent repair within 6 weeks of injury, and the remaining 3 patients underwent repair at a mean of 338 days after injury (95% CI, -42.8 to 718.8 days), a significant difference between groups (P = .006). All 13 patients were able to return to military duties at a mean of 6 months from injury. Patients treated within 6 weeks of injury had significantly higher functional outcomes (DASH score, 6.17 vs 26.67; P = .018; ASES score, 85.97 vs 49.5; P = .008), with greater strength performance compared with preinjury (bench press, 90.58% vs 38.95%; P = .0057; push-ups, 81.9% vs 23.8%; P = .023) compared with patients treated beyond 6 weeks of injury.

Conclusion

Operative repair of parachute-induced PM tears within 6 weeks of injury provided a superior functional and strength recovery when compared with delayed surgical repair. Acute repair should be recommended for military servicemembers who experience this unique injury mechanism.

Isokinetic Strength and Functional Scores after Rehabilitation in Jiu-Jitsu Fighter with Repair Surgery of Pectoralis Major Muscle Rupture: A Case Report

A pectoralis major muscle rupture is a rare injury that mainly occurs during exercise. This study examined the application of rehabilitation, strength and passive range of motion (ROM) change, and subjective assessment for 1 year undertaken after repair surgery of pectoralis major muscle rupture in a Jiu-Jitsu fighter. We hypothesized that the application of ROM exercises and rehabilitation strategies contributed to muscle recovery and successful return to sports. The patient was a 34-year-old man who was injured after falling during a competitive event. The patient had pain and swelling in the front of the chest and shoulder, and the distal chest was deformed. Imaging revealed a complete rupture of the pectoralis major muscle. Reparative surgery was performed by a specialist. Immobilization was performed one week after the surgery. Passive ROM exercises began with the forward flexion 2 weeks after the surgery; abduction and external rotation ROM exercises at 4 weeks; low-intensity muscle strength exercises using tube bands at 6 weeks; machine-based pectoralis major muscle exercises at 3 months. Isokinetic equipment was used to measure horizontal adduction and internal rotation strengths, and the subjective shoulder functional and ROM scores were evaluated. Recovery of shoulder function and ROM occurred at 3 months and muscle recovery at 6 months. The participant was able to return to sports at 5 months and compete at 7 months. Although this study explored only one patient's post-operative recovery, it suggests that ROM and strength exercises may be effective post-operative strategies for restoring function and strength to enable a return to sports.

Die Pectoralis-major-Ruptur (PMR) ist eine seltene Verletzung, die v. a. beim Kraftsport aufritt. Vorgestellt wird der Fall eines 31-jährigen Profibasketballspielers, der sich beim Bankdrücken eine Komplettruptur am muskulotendinösen Übergang des M. pectoralis major (PM) zugezogen hatte. Drei Wochen nach dem erlittenen Trauma erfolgte bei persistierenden Schmerzen und Kraftdefizit die Refixation des PM. Drei Monate postoperativ konnte der Patient bei vollem Bewegungsumfang schmerzfrei in den Basketballsport zurückkehren. Die Verletzungsentität wird vor dem Hintergrund der aktuellen Literatur diskutiert und das operative Vorgehen im Detail dargestellt.

Modified Jobe Versus Docking Technique for Elbow Ulnar Collateral Ligament Reconstruction: A Systematic Review and Meta-analysis of Clinical Outcomes

BACKGROUND

The modified Jobe and docking techniques are the most common techniques used for elbow ulnar collateral ligament (UCL) reconstruction. Previous systematic reviews have suggested that the docking technique results in superior outcomes as compared with the Jobe (figure-of-8) technique. However, these included results from earlier studies in which the flexor-pronator mass (FPM) was detached and an obligatory submuscular ulnar nerve transposition was performed.

PURPOSE/HYPOTHESIS

The purpose was to compare the outcomes and return-to-play (RTP) time between the docking and figure-of-8 techniques for UCL reconstruction. We hypothesized that there would be no significant difference in the proportion of excellent outcomes between techniques when the FPM was preserved and no obligatory submuscular ulnar nerve transposition was performed. We also hypothesized that there would be no significant difference in RTP time between techniques.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

This study was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. In the primary analysis, techniques were compared in random effects models by using the restricted maximum likelihood method, with weighted effect sizes calculated as the Freeman-Tukey double-arcsine transformed proportion of excellent outcomes for variance stabilization and with summary effects estimated from the inverse double-arcsine transformation per the harmonic mean of the sample sizes. Mean RTP times for techniques were compared in a separate model.

RESULTS

There were 21 eligible articles identified, with results for 1842 UCL reconstructions (n = 320, docking; n = 1466, figure-of-8). Without controlling for the effects of flexor-pronator detachment and submuscular ulnar nerve transposition, a significantly larger proportion of excellent outcomes was observed with docking reconstruction (86.58%; 95% CI, 80.42%-91.85%) than with figure-of-8 reconstruction (76.76%; 95% CI, 69.65%-83.25%; P = .031); however, there was no significant difference between techniques when controlling for FPM preservation or detachment with submuscular nerve transposition (P = .139). There was no significant difference between techniques in time to return to sports (P = .729), although no reconstructions with FPM detachment and submuscular ulnar nerve transposition were available for RTP time analysis.

CONCLUSION

There was no significant difference in the proportion of excellent Conway Scale outcomes or RTP time between the docking and modified Jobe techniques for UCL reconstruction when the FPM was preserved and routine submuscular ulnar nerve transposition was not performed.
