  • With the increasing use of arthroscopy and MRI for the diagnosis of shoulder problems, SLAP (superior labrum from anterior to posterior) lesions are more commonly diagnosed, and the incidence of SLAP repair surgery is increasing. Clinical diagnosis of SLAP is difficult to achieve, and many specific physical exam maneuvers have been described. However, neither these exam maneuvers nor history can provide a definitive diagnosis of a SLAP lesion. Despite this limitation, it is helpful to establish a more precise and accurate examination and to construct a preoperative plan. The purpose of this article is to review the original descriptions for specific physical exam maneuvers in SLAP, along with statistical analysis where available. This will help clinicians in deciding which tests are useful, how they should be implemented, and how to interpret the results.

  • SLAP(Superior labrum anterior to posterior) lesion is found in superior labrum injury alone and also combined with extension of the Bankart lesion(anteroinferior labral tear) in recurrent shoulder dislocation patients and rarely accompanied by the posterior Bankart lesion. There have been reports about SLAP lesions associated with various lesions, however, posterior type II SLAP lesion associated with posterior Bankart lesion has been rarely reported. In such a case, there are important technical tips in inserting anchors and suturing during arthroscopic repair. We experienced a rare case of posterior type II SLAP lesion associated with posterior Bankart lesion, occurred not after repetitive throwing(common mechanism) but after trauma in slipping down with the arm stretched during riding a bicycle. The satisfactory result was obtained after arthroscopic repair in this case.

  • Piston slap is not only one of the major sources of noise and vibration in internal combustion engines but also a cause of the deterioration of engine performance. The basic mechanism associated with the piston slap seems to be quite simple but the phenomenon is in fact complicated with regard to many mechanical elements associated, First of all the impact force of piston slap must be identified to estimate engine block surface vibration, In this paper model of collision point is proposed to calculate the impact force when slap surface vibration. In this paper model of collision point is proposed to calculate the impact force when slap occurs. The parameters of the model are estimated by employing the concept of point mobility, . The predicted and experimentally observed vibration results confirm that the proposed method is practically useful.

  • Superior labrum anterior to posterior (SLAP) lesions of the shoulder has recently been a popular issue to shoulder surgeons. Now we are correlating many shoulder symptoms to this SLAP lesion. A 45 year-old female patient injured her shoulder when her arm sleeve was entrapped in moving automobile door. A forceful pull of the arm in external and abduction position was suspected. She complained continuous shoulder pain with limited range of motion for 2 months. Magnetic resonance image showed possible SLAP lesion but no definite diagnosis were made prior to the operation. Arthroscopic evaluation revealed SLAP type Ⅱ lesion with concomitant avulsion of the superior glenoid cartilage. In addition anterior labrocapsular tear was seen from 7 to 9 o'clock of anterior glenoid. The SLAP lesion and the anterior capsulolabral lesion were repaired properly to the glenoid. We report a case of glenoid-cartilage avulsion type of SLAP Ⅱwith anterior labrocapsular lesion.

  • Purpose: We reviewed the SLAP lesions and associated injuries, also evaluated a hypothesis that the type II posterior SLAP lesion is related with posterior rotator cuff tear and gives rise to the postero-superior instability. Materials and Methods: The patient recording papers, MRI, video and operation sheets were reviewed with the 28 SLAP lesions confirmed by the arthroscopy among 242 cases. Among these SLAP lesions, type II was 22 cases and classified to the anterior, posterior(16 cases), combined subtype(6 cases) based on the main anatomic location. There were 14 cases of the type II accompanying rotator cuff tear. The average follow-up(13 months) results were evaluated with the ASES and Rowe rating score after repair or debridement of the SLAP lesions. Results: In the type II lesions accompanying the rotator cuff tears(14 cases), the posterior(l0 cases) and combined type(4 cases), cuff lesions were all existed posteriorly. Also We could confirm the drive-through sign in the eleven cases, though did not check the disappearance of this sign after repair because of retrospective study. We could followed up the 22 cases, 18 cases(77%) were excellent or good, fair 3 cases(14%) and poor 1 case(4%). Also, type II lesions with the rotator cuff tear(14 cases) were showed better results in the repair(8 cases) than the debridement(6 cases) of the unstable type II with the cuff repair. Conclusion: The type II lesions were frequently associated with the cuff tear in the specific location. We could presume the possibility of postero-superior instability in the SLAP lesion with the cuff injuries. Also, satisfactory results could be experienced when the unstable SLAP lesions with the cuff tear were repaired at the same time.

  • Purpose: This study reports the clinical results of the arthroscopic repair of type II SLAP lesion with bio-knotless anchor. Materials and Methods: 25 cases of 25 patients (20 male, 5 female) were included in this study. The average age was 44.5 years old. Preoperative ASES score was average 44. Arthroscopic SLAP repair with 1 or 2 bio-knotless anchors were performed in all cases. The average follow up period was 15 months. Results: The ASES score improved to average 92.7 at last follow up period and 23 cases had full range of motion of the shoulder. 2 case had mild limited range of motion of the shoulder without any problem in normal activity. Conclusion: Arthroscopic repair with bio-knotless anchor in type II SLAP lesion is one of the good methods because of the good clinical results.

  • Background: The purpose of this study is to evaluate results of superior labrum anterior to posterior (SLAP) repairs and debridement of type II SLAP lesions combined with Bankart lesions. Methods: Between 2010 and 2014, total 58 patients with anterior shoulder instability due to a Bankart lesion combined with a type II SLAP lesion were enrolled. Patients were divided into two groups: group C consisted of 30 patients, each with a communicated Bankart and type II SLAP lesion and group NC consisted of 28 patients, each with a non-communicated Bankart and type II SLAP lesion. Bankart repairs were performed for all patients. SLAP lesions were repaired in group C and debrided in group NC. Clinical results were analysed to compare groups C and NC by using the visual analogue scale pain score, American Shoulder and Elbow Surgeons score, Constant scores, Rowe score for instability and range of motion assessments. Results: The clinical scores were improved in both groups at final follow-up. Also, there were no differences between two groups. No significant difference was found in terms of the range of motion measured at the last follow-up. The number of suture anchors used was significantly higher in group C than in group NC (5.6 vs. 3.8; p=0.021). Conclusions: In this study, it is considered that Bankart repair and SLAP debridement could be a treatment option in patients with a non-communicated type II SLAP lesion combined with a Bankart lesion (study design: IV, therapeutic study, case series).

  • Piston slap is one of the major sources of noise in a 4-cycle diesel engine. Piston slap is not only one of major source mounted near the top and bottom of the piston thrust and antithrust skirts. Effects of engine speed, load and coolant temperature on piston motion were investigated. The measured piston motion showed 6 slapes per cycle resulting from the change of side force. Major piston slap timing was retarded as engine speeds became higher. The increase of engine load made large piston transverse movement toward thrust side of cylinder block. Piston transverse movement was due to reduced piston-liner clearance at higher coolant temperature.
