Background For volar soft tissue defects of the proximal interphalangeal (PIP) joint, free flaps are technically challenging, but have more esthetic and functional advantages than local or distant flaps. In this study, we compared the long-term surgical outcomes of arterial (hypothenar, thenar, or second toe plantar) and venous free flaps for volar defects of the PIP joint. Methods This was a single-center retrospective review of free flap coverage of volar defects between the distal interphalangeal and metacarpophalangeal joint from July 2010 to August 2019. Patients with severe crush injuries (degloving, tendon or bone defects, or comminuted/intra-articular fractures), thumb injuries, multiple-joint and finger injuries, dorsal soft tissue defects, and defects >6 cm in length were excluded from the study, as were those lost to follow-up within 6 months. Thirteen patients received arterial (hypothenar, thenar, or second toe plantar) free flaps and 12 received venous free flaps. Patients' age, follow-up period, PIP joint active range of motion (ROM), extension lag, grip-strength ratio of the injured to the uninjured hand, and Quick Disabilities of Arm, Shoulder & Hand (QuickDASH) score were compared between the groups. Results Arterial free flaps showed significantly higher PIP joint active ROM (P=0.043) and lower extension lag (P =0.035) than venous free flaps. The differences in flexion, grip strength, and QuickDASH scores were not statistically significant. Conclusions The surgical outcomes of arterial free flaps were superior to those of venous free flaps for volar defects of the PIP joint.

There has been considerable controversy as to the treatment method of dislocation of the acromioclavicular joint, so various operative treatment modalities have been suggested. We analyzed the results of 40 patients with acromio­clavicular dislocation, in whom twenty patients were treated by modified Phemister method and 20 patients by modified Weaver-Dunn method above follow-up two years. The purpose of this study was to compare the clinical results of two operative methods. According to Weitzman criteriae for clinical results, 12 cases were excellent, six cases good and two cases fair in modified Phemister method. But in modified Weaver-Dunn method, ten cases were excellent, eight cases good, one case fair and one case poor. In radiological result, coracoclavicular distance was measured at preoperative, postoperative and last follow-up period. The modified Phemister method was 6.lmm, 1.5mm and 2.4mm respectively, and the modified Weaver-Dunn method 7.8mm, 2.lmm and 2.5mm respectively. The complications were two cases of heterotopic ossification, one case of inadequate fixation and one case of K-wire breakage in modified Phemister method, and two cases of early fixation loss and one case of heterotopic ossification in modified Weaver-Dunn method. We obtained that the clinical, functional and radiological results showed no significant difference in two methods. The modified Phemister method was effective treatment for old patients in acute injuries due to short operation time and simple technique. The modified Weaver-Dunn method, as a reconstructive operation that reduces various complications for young and active male patients, was also good for getting the stability of coraco­clavicular ligament through clavicular bony union.

An indirect reduction through the bicipital groove and allogenic iliac tricortical bone graft was performed as a treatment for a large Hill-Sachs lesion with a rotator cuff tear in an acute traumatic shoulder joint dislocation in an elderly patient. Six months after surgery, the rotator cuff healing and bone union were confirmed. The patient also showed satisfactory clinical results with 95 points of the American Shoulder and Elbow Surgeons (ASES) shoulder score and active range of motion with 155° flexion, 120° abduction, and 70° external rotation and 30° internal rotation at 90° abduction. The surgical method can be considered for a large Hill-Sachs lesion with rotator cuff tear in an acute traumatic shoulder joint dislocation in elderly patients.

Purpose : To evaluate the functional and radiographic outcome of the modified Bosworth method in the surgical treatment of acute type V acromioclavicular joint dislocation. Materials and Methods: From June 1995 to May 1998, 20 patients were operated on for acute and complete acromioclavicular dislocation(Rockwood type V). The operative technique includes fixation of the coracoclavicular joint with Bosworth screw or 6.5mm cancellous screw and imbrication of trapezius and deltoid muscles. The average age was 34 years(range, 19 to 51 years). These 20 patients with an average follow-up of 18months, were evaluated clinically using the UCLA scoring system. Additional radiographical assessment was performed with stress radiographs. Results: Excellent or good clinical results were obtained in 95%(19 cases). And the average coracoclavicular interval ratio was decreased from 3.31(2.2-6.0) to 1.13(1-1.4) in stress radiographs. There were 4 cases of hetero­topic calcification postoperatively but there was no correlation with clinical result. Posttraumatic A-C joint arthritis was developed in one case. In that case, the distal clavicular resection was done under the arthroscopic technique. Conclusion: The severe displacement observed with type V injuries is incompatible with normal shoulder function if the shoulder is left in its displaced position. In type V injuries, significant damage to the deltoid and trapezius musculature and overlying fascia occurs, therefore open reduction and good fixation must be obtained with imbrication of trapezius and deltoid muscles. In our type V acute complete acromioclavicular dislocation, the modified Bosworth technique provides excellent results with a low complication rate.

Most studies on the pathophysiology, natural history, diagnosis by imaging and outcomes after operative or nonoperative treatment of rotator cuff tear have focused on those of full-thickness tears, resulting in limited knowledge of partial-thickness rotator cuff tears. However, a partial-thickness tear of the rotator cuff is a common disorder and can be the cause of persistent pain and dysfunction of the shoulder joint in the affected patients. Recent updates in the literatures shows that the partial-thickness tears are not merely mild form of full-thickness tears. Over the last decades, an improved knowledge of pathophysiology and surgical techniques of partial-thickness tears has led to more understanding of the significance of this tear and better outcomes. In this review, we discuss the current concept of management for partial-thickness tears in terms of the pathogenesis, natural history, nonoperative treatment, and surgical outcomes associated with the commonly used repair techniques.

Background: Neer type II distal clavicle fractures have the drawback of coracoclavicular instability and insufficient distal bony fragment, thereby making it difficult to achieve adequate fixation. Although various surgical treatments have been described for Neer type II fracture, the optimal treatment remains controversial. This study reports the clinical results and usefulness of anatomical locking plate with additional K-wire fixation. Methods: A totally of 21 patients with type II distal clavicle fracture were included in the study. The surgical procedure reduced the fracture temporarily; it included insertion of one or two K-wire from the lateral margin of the distal fragment to the proximal fragment through the fracture site, followed by application and fixation of the locking plate. The bony union and migration of K-wire was evaluated in the follow-up radiography. The coracoclavicular distance and acromioclavicular joint arthrosis were assessed at the final follow-up. The Constant Score (CS) and Korean Shoulder Score (KSS) were evaluated for clinical scoring. Results: Bone union was achieved in all cases. At the final follow-up, coracoclavicular distance of the injured shoulder was increased, as compared to the intact shoulder (p=0.002), with no accompanying clinical symptoms. No K-wire migration was observed. At the final follow-up, K-wire irritation was observed in two cases and acromioclavicular arthrosis in one case, with no other adverse effects. Pain visual analogue scale, CS, and KSS were improved in all cases. Conclusions: The method of anatomical locking plate with additional K-wire fixation could be useful in achieving beneficial clinical results.

Background: For Neer type IIB fracture of distal clavicle with coracoclavicular ligament injury, various surgical treatments have been used in literatures. However, there was no consensus on the optimal treatment. The aim of this study is to report the clinical and radiological results of open reduction and internal fixation of unstable distal clavicle fracture and suture augmentation of disrupted coracoclavicular ligament. Methods: A prospective study was performed in 23 patients with Neer type IIB distal clavicle fracture in Seoul Medical Center, Eulji Hospital, and National Medical Center. Firstly, suture anchors are inserted in the base of coracoid process and preliminary reduction was achieved by tie-off of three suture limbs around the clavicle. Then, the final fixation was completed with anatomical locking plate. Bony union and the distance between coracoclavicular ligaments were evaluated. Clinical results and complications including stiffness and secondary procedures were evaluated. Results: Bony union was achieved in all cases except one (22 of 23). At mean 14.9 months, no significant difference in the mean coracoclavicular distance was observed compared to uninjured shoulder ($8.2{\pm}7.9mm$ versus $7.3{\pm}3.4mm$, p=0.14). Pain visual analogue scale, American Shoulder and Elbow Surgeons score, Constant score, and Disabilities of the Arm, Shoulder and Hand score were 0.5, 83.4, 78.5, and 6.2, respectively. Revision surgery was performed in one case of nonunion. Four patients who complained of skin irritation underwent implant removal. Conclusions: In cases of an unstable distal clavicle fracture with coracoclavicular ligament disruption, satisfactory clinical results were obtained by locking plate fixation and coracoclavicular ligament suture augmentation concurrently.

Background: The aim of the present study was to determine the correlation between the amount of pain reduction after local anesthetic injection into the subacromial space preoperatively and clinical outcome after arthroscopic rotator cuff repair. Methods: A total of 127 patients who underwent arthroscopic rotator cuff repair and followed up at least 1 year were analyzed retrospectively. Preoperatively, a visual analogue scale (VAS) for pain was measured in all patients before and after the ultrasound guided impingement test. The participants were divied into four groups according to pain reduntion ater impingement test (Group A: >75%, Group B: 50%-75%, Group C: 25%-50%, Group D: <25%). VAS for pain, shoulder range of motion, shoulder isometric strength, ASES score were evaluated preoperatively and at 3, 6, 9, and 12 months postoperatively. Results: After surgery, the amount of pain reduction shows significantly at 3, 6 months in Groups A, B as compared to Groups C, D (p<0.05). Among the range of motion of shoulder joint, forward flexion was significantly improved in Group A at 3 months (p<0.05). The ASES score significantly improved at 3, 6 months in Groups A, B as compared to Group C, D (p<0.05). Conclusions: Preoperative degree of pain reduction after impingement test correlates with the improvement of pain after arthroscopic rotator cuff repair, especially in the early phase. Therefore, the impingement test could be effectively used.

Purpose : To assess the relationship between post-stroke shoulder pain, motor function, and pain-related quality of life(QOL) Methods : Volunteer sample of 62 chronic stroke survivors with post-stroke shoulder pain and glenohumeral subluxation. The patients answered the question in shoulder pain with the Brief Pain Inventory question 12 (BP1-12), Pain-related Quality of life(BPI-23). Therapists measured the performance of combined upper-limb movement including the hand-behind-neck(HBN), hand-behind-beck(HBB) maneuver, added passive pain-free shoulder external rotation range of motion, and Modified Ashworth Scale(MAS) score of the elbow flexors. Physical performance assessments were used to measure basic activity daily living(Modified Barthel Index-self care, MBI-S/C), motor function of upper limb(Fugl-Meyer Upper/Lower Extremity, FM-U/E). Results : Stepwise regression analyses indicated that post-stroke shoulder pain is associated with the BPI 23, but not with the FM-U/E, MBI-S/C. Thus, the presence of shoulder pain is more important predicting pain-related QOL than its degree in predicting motor function of upper limb and basic activity daily living. Conclusion : Post-stroke shoulder pain was associated with reduced quality of life related to pain. The pain was not associated with the motor function of upper limb and basic activity daily living. The result imply that management of shoulder pain & anatomical position of shoulder joint after stroke should be emphasized. This provides a further incentive to develop effective rehabilitation prevention and treatment strategies for post-stroke shoulder pain.
