A case report of re-implanting a neglected avulsion of supraspinatus tendon by arthroscopic and open surgeries.

INTRODUCTION: Rotator cuff constitutes a mechanical arm and an important stabilizing factor for the shoulder joint, and the supraspinatus muscle is the initiator of the movement of arm in the abduction direction. Rotator cuff injuries constitute an important part of the shoulder pain, and many cases are managed conservatively, nevertheless, open or arthroscopic surgery remains a must in many cases. CASE REPORT: We present the case of a patient in the sixth decade of life who complained of absence of abduction movement in his right shoulder three months ago after he lifted a heavy object. The clinical examination showed a positive sign of drop arm and other clinical signs indicating absence of supraspinatus muscle function. The MRI also showed a full-thickness tear of the supraspinatus tendon and its retraction away from its original inserting point on the greater tuberosity of the humerus. The case was managed by re-implanting the ruptured tendon by combining arthroscopic and open surgeries and using two anchors with slipable sutures, adopting the principles of duplicated knots and multiple transverse entry through the tendon to get a firm fulcrum. The results were clearly good after rehabilitation with a wide and powerful ROM (Range of Motion). DISCUSSION: Many cases of RCT (Rotator Cuff Tears) are concretively managed by using corticosteroids injections into the subacromial space with results of significant improvement in symptoms, and arthroscopic surgery is of increasing importance in preventing the development of small partial or full thickness tears and in reconnecting complete or avulsion tears early. The current case is characterized by a clear contraction of the completely avulsed tendon with severe adhesions due to neglection of the case for several months, which made the possibilities of arthroscopic surgeries limited only by acromioplasty, loosening some adhesions and preparation of the footprint, as well as making open surgery mandatory to give a wide area for doubling the suturing layers and then re-implanting the avulsed tendon into its original anchor. CONCLUSION: Neglect and delay in managing full-thickness tears in the supraspinatus tendon are the important reasons for the occurrence of adhesions and fibrosis, which in turn hinder the process of re-implanting the ruptured tendon at its original anchor through arthroscopic surgery, so that open surgery becomes the mandatory solution. It is necessary to use anchors with slipable threads and to focus on doubling the suturing layers with repeatedly entering through the muscle tendon to reduce it to the footprint firmly and strongly by tightening the slipable threads through the anchors.

A case report of surgical treatment of traumatic drop hand by quadruple tendons transfer.

INTRODUCTION: Drop hand is the case of inability to dorsiflexion of the hand and fingers according to radial nerve palsy (complete syndrome) or PIN (Posterior Interosseous Nerve) palsy (partial syndrome). Therefore, the patient loses part of the normal function of his/her hand causing life problems especially if it is the dominant hand. Tendon transfer is the main surgical treatment. CASE REPORT: We present a case of a young male who sustained multiple traumatic war injuries especially in the left upper limb; open humerus fracture, open ulna fracture, open radius fracture with a clear drop hand syndrome. After quadruple tendons transfer, he got a very good result especially in thumb movements with good ROM (Range Of Motions) in the wrist. DISCUSSION: Since it is difficult to restore full ROM and full muscular strength in the wrist and fingers of a drop hand with triple tendon transfer routinely, especially in the case of multiple injury to the upper extremity with the pronator teres being nonfunctional, we decided to perform quadruple tendon transfer depending on the tendons; FCR, PL, 3rdFDS, 4thFDS for stronger extension of the wrist, thumb, and other fingers. CONCLUSION: Our aim here is to confirm that the drop hand does not have standard findings in all cases. It may be a challenge, and may have atypical findings especially in the case of ipsilateral multiple traumatic limb, which in turn may have weakness or restriction in some important movements, so, it is important to keep in mind alternatives of tendon transfer.

Constraint-Induced Movement Therapy Combined With Botulinum Toxin for Post-stroke Spasticity: A Systematic Review and Meta-Analysis.

Stroke is considered one of the main causes of adult disability and the second most serious cause of death worldwide. The combination of botulinum toxin type A (BTX) with rehabilitation techniques such as modified constraint-induced movement therapy (mCIMT) has emerged as a highly efficient intervention for stroke patients to start synchronized motor function along with spasticity reduction. The current systematic review and meta-analysis were conducted in order to evaluate the available literature about the safety and efficacy of constraint-induced movement therapy (CIMT) combined with BTX in stroke patients with upper limb spasticity. Searches were conducted on WoS (Web of Science), Ovid, EBSCO-ASC&BSC, and PubMed for identifying relevant literature published from 2000-2020. Randomized Controlled Trials (RCTs) and Quasi-experimental studies were considered for inclusion. Rayyan (systematic review tool) QCRI (Qatar Computing Research Institute) was used for independent screening of the studies by two reviewers. For risk of bias and study quality assessment, Cochrane risk of bias tool (RoB 2) and Physiotherapy Evidence Database (PEDro) scales were used. Cochrane review manager was used to carry out the meta-analyses of the included studies. The search resulted in a total of 13065 references, of which 4967 were duplicates. After the title, abstract and full-text screening, two RCTs were deemed eligible for inclusion. Both the RCTs scored 8 on PEDro and were level evidence. The studies were heterogeneous. The findings of this meta-analysis in all the three joints post-stroke spasticity assessed on modified Ashworth scale (MAS) at four weeks post-injection aren't statistically significant (elbow P-value 0.74, wrist P-value 0.57, fingers P-value 0.42), however, according to one of the included studies the therapeutic efficacy of the combination of BTX-mCIMT injection assessed at four weeks post-injection in wrist and finger flexors was promising.  The effectiveness of BTX-CIMT combination over conventional therapy (CT) for improving post-stroke spasticity still needs to be explored with long-term, multicenter rigorously designed RCTs having a good sample size. However, the BTX-CIMT combination is promising for enhancing motor function recovery and improving activities of daily living (ADLs).

A case report of a rupture of the musculotendinous junction of the pectoralis major in an athlete.

INTRODUCTION: The pectoralis major muscle (PM) is a large muscle on the anterior chest wall. The rupture of the PM is a rare entity in literature and most incidences had been reported frequently in weight lifting and contact sports. Acute repair of PM rupture yielded better outcome as compared to non-operative treatment in active individuals who wish to return to their sports. CASE REPORT: We presented a case of a champion in bodybuilding who lifted a heavy weigh during his routine exercises, which caused a rupture in the musculotendinous junction of the left pectoralis major muscle. DISCUSSION: As it is rare to meet ruptures in this site of pectoralis major, we decided to insert anchors into the humeral bone (as in avulsions and tendon's tears), and to duplicate the suturing levels in multiple directions (as in muscular belly ruptures). CONCLUSION: Our aim here is to confirm that the rupture of the musculotendinous junction of the pectoralis major muscle is rare and difficult to deal, but the acute surgical treatment by inserting anchors into the humerus, and duplicating the suturing layers in multiple directions can give good results especially in athletes.

A case report of a fingerlike meniscal exostosis.

INTRODUCTION AND IMPORTANCE: The menisci are intra-articular fibrocartilagenous structures that optimize the joint function. They have several functions. Meniscal malformations are rare and different in shape. The most common are classified in public and known classifications, but some are very rare like finger like exostosis, so it is useful to highlight these rare malformations, that helps in the development of typing and classification, and may explain some unclear mechanisms of injuries. PROPRIOCEPTION: We know that meniscal tears in young people usually result from clear mechanical causes, like twisting or direct trauma, so we always need a cause, but when your patient does not explain a clear movement or mechanical trauma, you will ask and ask to conclude why. Yes, keep in mind that; it may be caused by a very rare congenital malformation. CASE PRESENTATION: A 20 years old male patient presented with a history of left knee pain for 6 months. MRI revealed a horizontal tear with abnormal thickness in the posterior horn of the lateral meniscus. The primary arthroscopic examination discovered a horizontal tear in the PHLM with atypical downward directed fingerlike exostosis. By using an arthroscopic hock, grasper and scissors, the exostosis was removed, and the nearby tear was smoothed with the shaver. CLINICAL DISCUSSION: Diagnosis of finger like exostosis is challenging and needs strong clinical suspicion because most of the time, it is not predictable and MRI signs may lead to unclear differential diagnosis. The presence of exostosis give a causative explanation of PHLM horizontal tear especially in absence of clear twisting or direct trauma. It may increase the forward directed pull forces of the nearest part of the meniscus during normal gait and gym exercises. CONCLUSION: Fingerlike exostosis and other meniscal malformations should be in mind as rare cases. They may explain the presence of tears in young patients with no clear trauma.

A case report of an arthroscopic-assisted fixation of a small Hoffa fracture in a young patient.

INTRODUCTION: Hoffa fracture is a type of rare tangential supracondylar distal femoral fracture. The most common mechanism of this fracture injury is high energy trauma. In some cases, its poor visibility on X-rays makes its diagnosis difficult and needs more than routine X-rays. Treatment methods include conventional ORIF, or arthroscopy-assisted fixation as a more challenging method. CASE REPORT: We present a case of a young female patient who sustained a low energy injury trauma to her left knee, which caused in a small minimally displaced lateral unicondylar Hoffa fracture. DISCUSSION: Although it needs more experience and special tools, arthroscopy-assisted fixation of Hoffa fracture provides a good method of treatment, and it has many advantages over open method. CONCLUSION: Our aim here is to confirm that Hoffa fracture may occur even with low energy knee trauma, and that arthroscopy-assisted fixation is a successful, applicable and alternative method to ORIF for small and thin osteochondral fragments, and could provide good stability and union even when using only one screw for fixation.
