RESUMEN
The conventional hand tendon zones and subzones do not reflect the actual lengths covered by the involved locus of the tendon during full digital and wrist motion, which warrant reappraisal of the tendon zone concept. Because of the tendon excursions many lacerations should be regarded as multiple zone injuries. Furthermore, the length-spans of glide of the distal tendon stump and of the tendon junction (i.e. the glide zones of tendon injury and repair, respectively) are mostly not of the same length because, due to pulley release and bulkiness of the tenorrhaphy, the glide zone of tendon repair is shorter than that of tendon injury. Therefore, it would be practical to notate the glide zones of the lacerated tendon by indicating the anatomic position of the distal tendon stump and tendon junction in full extension and flexion. This data can be provided separately or along with the conventional tendon zones, e.g. II (A4-C2) or II-III (A2-PA), where A, C, and PA stand for the annular, cruciform, and palmar aponeurosis pulleys, respectively. The conventional tendon zone classification could be improved with a tendon glide zone concept. Documentation of the actual excursions of the distal tendon stump and of the tenorrhaphy interface would prevent misinterpretation of the actual level of tendon injury and repair.

Mallet finger injuries are a common presentation in the emergency department. These injuries result from a forced flexion at the distal interphalangeal joint (DIPJ) that causes extensor tendon disruption, and possibly bone avulsion, at the base of the distal phalanx. This article describes the anatomy, mechanisms, classification and assessment of mallet finger injury. It reviews different types of splints used in the conservative management of closed tendinous mallet finger injury and discusses the latest evidence regarding immobilisation methods and treatment duration. Maintaining the DIPJ in extension during treatment is essential, so the article stresses the importance of patient adherence to treatment.

BACKGROUND: The authors sought to determine the reliability of the Soong classification, which relates the position of the implant to the watershed line of the distal radius, for predicting flexor tendinopathy in distal radius fractures treated with volar plate fixation. METHODS: Medical records were reviewed, including demographics, fracture and operative characteristics, tendon-related complications, and radiographic outcomes. Six hundred fifty-nine distal radius fractures were reviewed with a mean duration of clinical follow-up of 12.9 ± 0.7 months. RESULTS: The incidence of isolated flexor tendinopathy and tendon rupture was 0.9 and 0.3 percent, respectively. The Soong classification failed to independently predict flexor tendon rupture or tendinopathy. Fractures classified as inadequately reduced were significantly associated with Soong grade 0 or grade 2, whereas adequately reduced fractures were significantly associated with Soong grade 1. CONCLUSION: The Soong classification is not the sole predictor of flexor tendinopathy and may be viewed as a reflection of the overall appropriateness of fracture reduction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

PURPOSE: The aim of this study was to evaluate the factors that influence the prognosis for patients with sagittal band injuries who were treated nonsurgically. METHODS: A total of 94 patients who had been diagnosed with traumatic sagittal band injury and initially treated with 7 weeks of metacarpophalangeal (MCP) joint extension orthosis wear (5 weeks of full-time followed by 2 weeks of part-time use) were studied. The response to treatment, including finger range of motion (ROM), extensor tendon instability, grip strength, and functional outcome measured as Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score were assessed at 24-week follow-up. The factors that were assessed for their influence on the outcomes were age, sex, occupation, hand dominance, type of injury, injury severity, time to treatment, and the duration of orthosis wear. Potential predictor variables in bivariate analyses were entered into multivariable analyses to determine prognostic indicators of the outcomes. RESULTS: After 24 weeks' follow-up, 67 patients (71%) achieved resolution of symptomatic tendon translocation with 83% of grip strength and 90% of ROM compared with the unaffected hand. The final mean QuickDASH scores was 15. Twenty-seven patients (29%) had persistently symptomatic tendon subluxation, and of those, 18 (19%) underwent surgical repair. There were significantly more manual laborers in the failure group than in the success group. Subjects in the treatment failure group were older, had longer symptom durations, and were more likely to have grade III injuries than were those in the success group. Multivariable analysis revealed that manual labor, longer symptom duration, and grade III injury were associated with a higher likelihood of treatment failure. CONCLUSIONS: An MCP extension orthosis for sagittal band injury (5 weeks of full-time followed by 2 weeks of part-time use) led to mostly satisfactory results with 71% of patients achieving resolution of symptomatic tendon translocation, but manual labor, longer symptom duration, and grade III injury were associated with a higher likelihood of treatment failure. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

BACKGROUND: To introduce a (semi-)quantitative surgical score for the classification of rotator cuff tears. MATERIAL AND METHODS: A total of 146 consecutive patients underwent rotator cuff repair and were assessed using the previously defined Advanced Rotator Cuff Tear Score (ARoCuS) criteria: muscle tendon, size, tissue quality, pattern as well as mobilization of the tear. The data set was split into a training (125 patients) and a testing set (21 patients). The training data set fitted a nonlinear predictive model of the tear score based on the ARoCuS criteria, while the testing data served as control. Based on the scoring results, rotator cuff tears were assigned to one of four categories (ΔV I-IV) and received a stage-adapted treatment. For statistical analysis, mean values ± standard deviation, interclass correlation coefficients (ICC) and kappa values were calculated. RESULTS: Overall, 32 patients were classified as ΔV I, 68 as ΔV II and 37 as ΔV III. Nine patients showed ΔV IV tears. Patients of all ΔV groups improved significantly their Constant scores (p < 0.001) and profited from significant pain reduction after surgery (p < 0.001). To date, ten patients have undergone revision surgery with five of them primarily classified as ΔV IV. Kappa values for the interobserver reliability ranged between 0.69 and 0.95. ICC scores for the ΔV category were 0.95 for interobserver reliability. CONCLUSIONS: The ARoCuS facilitates intra-operative decision-making and enables surgeons and researches to document rotator cuff tears in a standardized and reproducible manner.

INTRODUCTION: The purpose of this study was to determine whether tears of the peroneus brevis (PB) tendon correlate with increased fatty infiltration of the PB muscle on MRI compared with musculature without clinical evidence of peroneal pathology. METHODS: Ankle MRI scans of patients with PB tendon tearing (tear group) were compared with those of patients without clinical evidence of peroneal pathology (control group). Two reviewers graded the PB muscle belly according to the Goutallier classification. RESULTS: Thirty patients were included in each group. The mean Goutallier scores for the tear and control groups were 0.52 (±0.72) and 0.05 (±0.15), respectively (P = 0.0019). The level of interobserver agreement between reviewers was moderate (intraclass correlation coefficient = 0.75; 95% confidence interval, 0.57 to 0.85). DISCUSSION: Patients with PB tendon tear demonstrate markedly higher grades of fatty degeneration compared with patients without peroneal pathology. The Goutallier classification may become a valuable instrument for assessing the severity of a PB tear. LEVEL OF EVIDENCE: Level III-diagnostic study.

Aims: The aim of the study was to analyze the results of primary tendon reinsertion in acute and chronic distal triceps tendon ruptures (DTTRs) in the general population. Patients and Methods: A total of 28 patients were operated on for primary DTTR reinsertions, including 21 male patients and seven female patients with a mean age of 45 years (14 to 76). Of these patients, 23 sustained an acute DTTR and five had a chronic injury. One patient had a non-simultaneous bilateral DTTR. Seven patients had DTTR-associated ipsilateral fracture or dislocation. Comorbidities were present in four patients. Surgical treatment included transosseous and suture-anchors reinsertion in 22 and seven DTTRs, respectively. The clinical evaluation was performed using Mayo Elbow Performance Score (MEPS), the modified American Shoulder and Elbow Surgeons Score (m-ASES), the Quick Disabilities of the Arm, Shoulder and Hand score (QuickDASH), and the Medical Research Council (MRC) Scale. Results: A total of 27 patients (28 DTTRs) were available for review at a mean of 47.5 months (12 to 204). The mean MEPS, QuickDASH, and m-ASES scores were 94 (60 to 100), 10 (0 to 52), and 94 (58 to 100), respectively. Satisfactory results were observed in 26 cases (93%). Muscle strength was 5/5 and 4/5 in 18 and ten DTTRs, respectively. One patient with chronic renal failure experienced a traumatic rerupture of distal triceps. One patient (1 DTTR) experienced mild elbow stiffness. Conclusion: Primary repair of acute and chronic DTTRs in a general population yields satisfactory results in the majority of patients with a low rerupture rate.

The extensor mechanism of the knee-consisting of the four muscles of the quadriceps, the quadriceps tendon, the patella, and the patellar ligament-is essential for lower extremity function during both standing and ambulation. The presence of articular cartilage and growing physes in the pediatric knee, coupled with the generation of significant tensile force, creates an opportunity for pathology unique to the pediatric population.Tibial tubercle fractures and patella injuries are quite rare, and even pediatric-trained orthopaedic surgeons may not be exposed to these injuries on a regular basis. It is the intent of this article to discuss the current literature regarding the mechanism of injury, diagnostic workup, classification, indications for surgical versus non-surgical management, and techniques for operative management for both tibial tubercle and patella (transverse and sleeve) fractures.

BACKGROUND: This study analyzes position of the peroneal tendons and status of the superior peroneal retinaculum (SPR) whenever a lateral malleolar bony flake fracture occurs. METHODS: Twenty-four patients had a lateral malleolar bony fleck on anteroposterior ankle radiographs, either in isolation or associated with other hindfoot injuries. We studied size of the bony flecks, presence or absence of peroneal tendon dislocation and pathoanatomy on CT scans. RESULTS: In 11 patients, a small bony fleck lies within the superior peroneal retinaculum and contiguous periosteum, which are stripped off the lateral fibula (Class II lesions). Tendons dislocate into the subperiosteal pouch thus formed, resembling Class I lesions without associated bony avulsion. Treatment for Class II is same as for Class I injuries. In 8 patients with a big bony fleck, tendons dislocate into the fracture site and SPR is intact (Class III lesions). In Class IV lesions, observed in 5 patients with 2-part calcaneal fracture/dislocation, SPR remains intact and peroneal tendons are not dislocated. The invariably large fleck results from the displacing lateral calcaneal fragment abutting against the fibula, whereas the dislocating tendons cause the bony avulsions in Classes II and III. CONCLUSIONS: Due to pathoanatomical differences, surgical approach and natural history of neglected lesions differ depending on size of the bony fleck. The SPR must not be incised in case of big Class III flecks.

PURPOSE: The current literature describes multiple surgical and nonsurgical techniques for the management of mallet finger injuries, and there is no consensus on the indications for surgical treatment. The objective of this study was to determine, through a literature review, if any conclusions can be drawn concerning the indications for surgery in mallet finger injuries; the treatment outcomes of surgical versus nonsurgical management; the most effective methods of surgical and nonsurgical treatment; and the most common treatment complications of mallet finger injuries. METHODS: A systematic review of multiple databases was performed. English language clinical studies evaluating therapeutic interventions for mallet fingers that reported objective, standardized outcome measures were included. Basic science studies, cadaveric studies, conference abstracts, level V evidence studies, studies lacking statistical data, and tendinous injuries other than mallet fingers were excluded. Salvage procedures and studies evaluating exclusively chronic lesions were also excluded. RESULTS: Forty-four studies that reported clinical outcomes for the treatment of mallet finger injuries, 22 evaluating surgical treatments and 17 studies investigating nonsurgical treatments were included. The average distal interphalangeal joint extensor lag was 5.7° after surgical treatment and 7.6° after nonsurgical treatment. Complication rates of surgical and nonsurgical interventions were comparable (14.5% and 12.8%, respectively). Five studies directly compared the outcomes of surgical with nonsurgical management, with mixed results and recommendations. CONCLUSIONS: Both surgical and nonsurgical treatments of mallet finger injuries lead to excellent clinical outcomes. Insufficient evidence is available to determine when surgical intervention is indicated. Based on our literature review, it appears that these treatments are equivalent and should be individualized to the patient. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

We report the results of interposition tendon grafts using the ipsilateral palmaris longus tendon in 12 patients with closed flexor digitorum profundus tendon ruptures in zone III or IV of 14 digits between June 2006 and October 2015. Before surgery, 2 patients were diagnosed with closed tendon ruptures that occurred after nonunion of hamate hook fractures. The other 10 patients were diagnosed with spontaneous tendon ruptures of unknown cause. In 2 of the 10 patients with spontaneous tendon rupture, the cause of the rupture was not found. In the other 8 patients, there was rough surface with deficient overlying soft tissue on the radial side of the hamate hook. In all cases, the ruptured flexor digitorum profundus was reconstructed by applying overtension on the tendon graft, causing greater flexion than for the other normal digits. Hamate hook excision was also performed on 10 subjects with abnormalities. Postoperatively, the patients were followed for an average of 22.5 months (range, 12-64 months). At the final follow-up, the mean Disabilities of the Arm, Shoulder, and Hand questionnaire score was 5.7 (range, 3.3-8.3). There were excellent results in all 14 digits according to Strickland and Glogovac criteria. The mean total active motion was 167 degrees (range, 160-180 degrees). There were no surgical complications, including infection, adhesions, or tendon rerupture. There were excellent clinical results with the interposition tendon graft using palmaris longus for closed tendon rupture in zone III or IV of the hand. Applying overtension to the grafted tendon appears to be beneficial.

Extension of the fingers is a complex act. Boutonnière deformity is defined by flexion at the proximal inter-phalangeal (PIP) joint and hyperextension at the distal interphalangeal (DIP) joint due to disruption of the central slip of the extensor tendon. Swan neck deformity is defined by hyperextension at the PIP joint and flexion at the DIP joint, and the pathology is divided into intrinsic, extrinsic, and articular. The deformities are a result of imbalance of the tendons and ligaments in the fingers. Treatment is depending on the underlying cause and includes surgery and non-operative treatment. Functional gain and risk must be realistically assessed.

Traumatic avulsion of flexor digitorum profundus (jersey finger) is an uncommon injury. Our study aimed to describe functional outcomes of jersey fingers after surgical treatment. From January 2004 to 2014, we performed surgery on 32 patients who had jersey finger. Twenty-six of these patients were male and 6 were female with a mean age of 37.2years (range 16-68). Of the 32 cases, 11 were sports injuries, 16 presented on the ring finger and 13 on the little finger. Using the Leddy and Packer and Smith classifications, 16 of the injuries were type I, 4 were type II, 5 were type III, 7 were type IV. The mean time between injury and surgery was 6.8days (range: 0-32). The surgical techniques used were anchor, pull-out, or an association of both these techniques. Prior to the patient discharge, functional outcomes were evaluated. Twenty-nine patients were evaluated in total and three patients were lost. Of the 29, the average time between surgery and discharge was 36.6months ranging from 4.5 to 118months. According to the Buck-Gramcko classification, six patients had an excellent result, six had a good result, seven had a satisfactory result and ten a poor result. The mean Quick DASH score immediately to prior discharge was 5.66 (range: 0-56.82). Twelve complications were reported on nine patients. No infections were reported. Rapid diagnosis and rapid surgical treatment led to restoration of full range motion.

Chronic Achilles tendon lesions (CATLs) ensue from a neglected acute rupture or a degenerated tendon. Surgical treatment is usually required. The current English literature (PubMed) about CATLs was revised, and particular emphasis was given to articles depicting CATL classification. The available treatment algorithms are based on defect size. We propose the inclusion of other parameters, such as tendon degeneration, etiology, and time from injury to surgery. Partial lesions affecting less than (I stage) or more than (II stage) half of the tendon should be treated conservatively for healthy tendons, within 12 weeks of injury. In II stage complex cases, an end-to-end anastomosis is required. Complete lesions inferior to 2 cm should be addressed by an end-to-end anastomosis, with a tendon transfer in the case of tendon degeneration. Lesions measuring 2 to 5 cm require a turndown flap and a V-Y tendinous flap in the case of a good-quality tendon; degenerated tendons may require a tendon transfer. Lesions larger than 5 cm should be treated using two tendon transfers and V-Y tendinous flaps. A proper algorithm should be introduced to calibrate the surgical procedures. In addition to tendon defect size, tendon degeneration, etiology of the lesion, and time from injury to surgery are crucial factors that should be considered in the surgical planning.

BACKGROUND: Closed avulsion injury of the flexor digitorum profundus (FDP) tendon is a relatively common condition of the hand. Its present classification system seems to be deficient in including all possible patterns of injury, leading to improper selection of the best treatment method for the injury. We aim to provide a new classification scheme for this injury. METHODS: We developed a new classification scheme based on the possible pattern of FDP tendon injury. It consisted of three main types, and 10 sub-types. This was used to classify the injury of 34 patients, and help in choosing the best management approach. All patients underwent surgical treatment of their injury. The distal interphalangeal (DIP) joint extension deficit and total active motion (TAM) of the proximal interphalangeal (PIP) and DIP joints were considered as the main outcomes. Five orthopaedic surgeons used the new classification system for our cases, and the inter-rater reproducibility was tested with Fleiss' kappa. RESULTS: The multi-rater kappa for the classification was excellent. At the final follow-up visit 24 months following surgery, the mean loss of extension of the DIP joint was 13.76° ± 13.53° (range 0° to 45°), while the mean TAM was 148.88° ± 22.64° (range 94° to 172°). Based on the TAM score, 21 (61.76%), 8 (23.53%) and 5 (14.71%) patients had excellent, good and fair results, respectively. None of our patients had poor results. CONCLUSIONS: Our new classification scheme of FDP tendon avulsion appeared to be comprehensive and useful in guiding the surgeon for the best treatment option. Nevertheless, this should be confirmed by using it for larger number of patients with different patterns of injury.

Tibialis posterior tendon dislocation is a rarely described entity that is easily missed, resulting in delayed diagnosis and treatment. A review of the English published data on the topic showed inconsistency in the reporting of injuries and surgical management techniques, leading us to describe a novel classification system to guide treatment and future reporting. We also describe a case of tibialis posterior tendon dislocation in a professional volleyball player and our surgical technique for correction, including retromalleolar groove deepening.

PURPOSE: To assess the inter- and intraobserver agreement for classification and management of subscapularis tendon pathology based on arthroscopy and magnetic resonance imaging (MRI). METHODS: Twenty-two orthopaedic surgeons from the Multicenter Orthopaedic Outcomes Network (MOON) shoulder group reviewed still arthroscopic and MRI images of the subscapularis tendon from patients with a random assortment of subscapularis morphology. The surgeons were asked to classify the pathology based on 2 systems (Lafosse and Lyons) and choose whether they would repair the tendon and, if so, the method of repair (open or arthroscopic). The survey was administered 3 times to each surgeon. Inter- and intraobserver reliability between testing rounds was determined by kappa analysis. RESULTS: Interobserver reliability on classification of tears was poor based on MRI (k = 0.18 to 0.19) and fair based on arthroscopy (k = 0.26 to 0.29). Interobserver agreement on whether surgical treatment was indicated was fair for both MRI (k = 0.28) and arthroscopy (k = 0.38), while the agreement for type of surgery was poor based on MRI (k = 0.18) and fair based on arthroscopy (k = 0.28). Interobserver agreement did not improve when both MRI and arthroscopy were provided simultaneously (k = 0.24 to 0.30). Intraobserver reliability for classification and treatment was fair to moderate for both MRI (k = 0.32 to 0.50) and arthroscopic imaging (k = 0.39 to 0.56). When considering just those patients with normal tendons, surgeon agreement improved. For all questions, the arthroscopic images had a higher level of agreement among surgeons than the MRI (P < .001). CONCLUSIONS: Although surgeons tended to have higher reliability when presented with arthroscopic images compared with MRI, there was very little agreement on the classification and management of subscapularis tendon tears.

PURPOSE: To assess the reliability and reproducibility of the Goutallier/Fuchs classification for the evaluation of abductor tendon tears of the hip, as well as to identify the relation between preoperative tear size, abductor muscle quality, and the success of endoscopic tendon repair. METHODS: This is a retrospective review of 30 consecutive endoscopic abductor tendon repairs performed by a single surgeon over a 2-year period. Preoperative magnetic resonance imaging scans were reviewed, and the muscle was assigned a grade according to the Goutallier/Fuchs classification. Patient-rated outcome scores--visual analog scale score, Hip Outcome Score (HOS), and modified Harris Hip Score (mHHS)--were collected preoperatively and at a minimum of 2 years postoperatively. Intraobserver and interobserver reliability for muscle grading was calculated. Postoperative outcome measures were compared with preoperative tear size, muscle grade, and repair type to assess for correlations. RESULTS: Of the 30 hips included in the study, over 75% were classified as grade 1 (n = 15) or grade 2 (n = 8). The intraobserver reliability and interobserver reliability of the classification system averaged 0.872 and 0.916, respectively. Two patients (grades 3 and 4) had repair failure and underwent muscle transfer. In the remaining 28 hips, improvement was seen in the visual analog scale score (6.0 v 1.7, P < .0001), HOS-Activities of Daily Living subscale score (58.8 v 83.4, P < .0001), HOS-Sport-Specific subscale score (40.0 v 75.0, P < .0001), and mHHS (55.6 points v 81.1 points, P < .0001) postoperatively. Increasing preoperative fatty infiltration and atrophy correlated with increased postoperative pain levels (regression coefficient, 0.93; P < .001) and decreased postoperative HOS-Activities of Daily Living subscale scores (regression coefficient, -3.36; P = .011), HOS-Sport-Specific subscale scores (regression coefficient, -5.63; P = .016), mHHS values (regression coefficient, -3.50; P = .0008), and patient satisfaction (regression coefficient, -1.04; P < .0001). Patient age, tear size, or repair type (double v single row) did not affect postoperative outcomes. CONCLUSIONS: The Goutallier/Fuchs classification system can be reliably and reproducibly applied to the evaluation of abductor tendon tears of the hip and appears to correlate with patient-rated outcomes after repair. Increasing preoperative muscle fatty atrophy correlates with increased patient pain and decreased patient satisfaction and functional outcomes after repair. LEVEL OF EVIDENCE: Level IV, prognostic case series.
