ABSTRACT

OBJECTIVE: Elimination of pain or instability by arthrodesis of the thumb joint in functional position by dorsal plateosteosynthesis. INDICATIONS: Painful primary or secondary arthrosis of the thumb, nonreconstructable ulnar, radial or palmar instability, posttraumatic dislocation, defect injuries, bone tumors in the region of the thumb metacarpophalangeal joint. CONTRAINDICATIONS: Local infection of the thumb metacarpophalangeal joint area. SURGICAL TECHNIQUE: Dorsal approach to the thumb metacarpophalangeal (MP) joint, splitting of the extensor aponeurosis between the extensor pollicis longus and extensor pollicis brevis tendon. Opening of the anterior capsule and separation of the collateral ligaments, open up the joint, narrow concave and convex joint surface resections, adjustment of the arthrodesis position in 10-20° flexion and K­wire transfixation, dorsal plateosteosynthesis, fine adjustment of the flexion, axis and pronation position. Closure of the capsule and the periosteal gliding tissue over the plate, reconstruction of the extensor aponeurosis. POSTOPERATIVE MANAGEMENT: Splint for 3 weeks. Full load after 6-8 weeks. RESULTS: The dorsal plate arthrodesis of the thumb MP joint is a reliable surgical method with very good functional results.

ABSTRACT

Among the carpal bones the scaphoid (Os scaphoideum) is the most important. The most frequent fracture of the carpus is a fracture of the scaphoid bone. The frequently occurring absence of healing of these fractures as well as unhealed ruptures of the ligament complex between the scaphoid and lunate, lead to the most severe biomechanical and thus the most severe clinical changes of the wrist. The detailed anatomy of the scaphoid, blood flow, ligament attachments, injury mechanisms and pathobiomechanics are described and illustrated.

ABSTRACT

BACKGROUND: After controversial discussions in the literature about therapy regimens for calcaneal fractures, a retrospective study of patients operatively treated in a maximum care trauma center was conducted. OBJECTIVE: Investigation of the influencing factors on the treatment quality of operatively treated patients with calcaneal fractures. MATERIAL AND METHODS: Between 2005 and 2013 a total of 90 patients with calcaneal fractures were surgically treated in this hospital with locking plate osteosynthesis. A total of 48 patients with 55 fractures were retrospectively investigated. The assessment with respect to posttraumatic arthrosis was made radiologically and Böhler's and Gissane's angles were also determined. Clinically AOFAS and SF-36 scores were documented. The results were statistically tested with respect to possible risk factors. RESULTS: A total of 9 patients (18.8%) were found with complications necessitating operative revision, with 8 patients requiring subtalar arthrodesis and 1 patient with a deep wound infection. Nicotine abuse and a long interval between trauma and reconstructive surgery were identified as factors that influenced the development of wound healing problems. The average AOFAS score was 68 points and the SF-36 was 58.86 points. A poor result in the scores was caused by the development of symptomatic arthritis and the type of insurance. In this cohort factors, such as age and complexity of fractures were not correlated with a poor result. CONCLUSION: In this patient collective nicotine abuse and a long interval between trauma and surgery were risk factors for development of wound infections. Other factors with an influence on the outcome were the postoperative development of arthritis and the type of health insurance; however, patient age had no impact on the outcome.

ABSTRACT

PURPOSE: Flexor tendon repair consists of circumferential peripheral sutures in combination with core sutures to avoid fraying and reduces the exposure of suture material on tendon surface. The peripheral suture adds up to a tenfold increase of the biomechanical stability compared to the core suture alone. The purpose of our study was to determine the most favourable peripheral repair technique for tendon repair. METHODS: Seventy-two porcine flexor tendons underwent standardized tenotomy and repair using one of the following six methods (n = 12): simple-running (SR), simple-locking (SL), Halsted-mattress (HM), lin-locking (LL), Lembert-mattress (LM), and Silfverskiöld cross-stich (SCS) suture technique. The SL- suture was placed 2 mm; the HM, LM, SC, and LL suture were placed 5 mm from the tendon gap. The SR suture was placed 1, 2, and 3 mm from tendon ends; no additional core suture was applied. For cyclic testing (1000 cycles), elongation was calculated; for load to failure construct stiffness, yield load and maximum load were determined. RESULTS: The mean cyclic elongation for all tested suture techniques was less than 2 mm; there was no significant difference between the groups regarding elongation as well as yield load. The HM, LM, SCS, and LL suture techniques presented significantly higher maximum loads compared to the SR- and SL-sutures. The 3 mm SR showed significantly higher maximum loads compared to the 2 and 1 mm SR. CONCLUSIONS: Beside the distance from tendon gap, the type of linkage of the suture material across and beneath the epitendineum is important for biomechanical stability. Simple-running suture is easy to use, even with a slight increase of the distance from tendon gap significantly increases biomechanical strength. For future repairs of flexor tendon injuries, 3 mm stitch length is highly recommended for simple peripheral suture, while the Halsted-mattress suture unites the most important qualities: biomechanically strong, most part of suture material placed epitendinous, and not too complicated to perform.

ABSTRACT

INTRODUCTION: 3T MRI has become increasingly available for better imaging of interosseous ligaments, TFCC, and avascular necrosis compared with 1.5T MRI. This study assesses the sensitivity and specificity of 3T MRI compared with arthroscopy as the gold standard. PATIENTS AND METHODS: Eighteen patients were examined with 3T MRI using coronal T1-TSE; PD-FS; and coronal, sagittal, and axial contrast-enhanced T1-FFE-FS sequences. Two musculoskeletal radiologists evaluated the images independently. Patients underwent diagnostic arthroscopy. RESULTS: The classifications of the cartilage lesions showed good correlations with the arthroscopy findings (κ = 0.8-0.9). In contrast to the arthroscopy, cartilage of the distal carpal row was very good and could be evaluated in all patients on MRI. The sensitivity for the TFCC lesion was 83%, and the specificity was 42% (radiologist 1) and 63% (radiologist 2). For the ligament lesions, the sensitivity and specificity were 75 and 100%, respectively, with a high interobserver agreement (κ = 0.8-0.9). DISCUSSION: 3T MRI proved to be of good value in diagnosing cartilage lesions, especially in the distal carpal row, whereas wrist arthroscopy provided therapeutic options. When evaluating the surgical therapeutical options, 3T MRI is a good diagnostic tool for pre-operatively evaluating the cartilage of the distal carpal row.

ABSTRACT

The exact knowledge of the anatomy of the fibrous skeleton of the hand is an absolute prerequisite for any treatment of Dupuytren's disease. The fibrous skeleton does not only include the palmar aponeurosis, but also numerous retinacula cutis, which are not found in current anatomy books. Here, eponyms facilitate the otherwise difficult and over-pronounced names of the fiber systems. Skoog, Legueu and Juvara, Gosset, Grapow, Grayson, Cleland, Thomine, and Barton are the most important. This systematic review of the fibers and strands is designed to help reduce iatrogenic complications.

ABSTRACT

The scaphoid is biomechanically and clinically of great importance for function of the wrist. In the literature, its anatomy and biomechanics are clearly underrepresented as well as underestimated. In the following review the scaphoid will be presented in more detail, according to recent information and findings. Not only will the origin of the name and the history of previous names, such as cotyloid or navicular, be introduced, but also for the first time in medical literature the significant phylogeny and ontogeny of the scaphoid will be shown. Moreover, the clinically very important blood supply, the ligaments of the scaphoid and relevant biomechanical details will be described.

ABSTRACT

Restoration of stability of the thumb represents an enormous gain of function for the patient and can be achieved by arthrodesis or ligament reconstruction. Ligament reconstruction should only be performed if good stability and mobility and a pain-free grip can also be achieved. In every case surgery must protect the delicate soft tissues and should be based on a profound knowledge of the anatomical and biomechanical circumstances. Instability of the trapeziometacarpal joint is rare but metacarpophalangeal joint instability (ulnar, palmar and radial) is relatively frequent. For both conditions arthrodesis is the most frequently used and easier surgical procedure. Ligament reconstruction is more difficult to perform but can maintain the mobility of these joints.

ABSTRACT

INTRODUCTION: Porcine flexor tendons, bovine extensor tendons, and human (semitendinosus) tendons are frequently used as substitutes for human ACL grafts in biomechanical in vitro studies. This study compares the biomechanical properties and structural differences of these tendons. MATERIALS AND METHODS: In this biomechanical study, fresh-frozen porcine flexor tendons, bovine extensor tendons, and human semitendinosus tendons were used (n = 36). The tendons were mounted in a uniaxial testing machine (Zwick/Roell) with cryo-clamps, leaving a 60 mm tendon part free between the two clamps. Specimens have been loaded to failure to evaluate the biomechanical parameters stiffness, yield load, and maximum load. A Total Collagen Assay Kit was used to detect differences in the total collagen type I concentration (n = 30). A one-way ANOVA was performed to detect differences in the means. The significance level was set at p < 0.05. RESULTS: There were no significant differences in the stiffness between the groups (bovine 194 ± 43 N/mm, porcine 211 ± 63 N/mm, and human cadaveric 208 ± 58 N/mm). The yield and maximum loads were high (>1000 N) in all groups, but they were significantly increased in both animal specimens (means of 1681-1795 N) compared with human cadaveric specimen (means of 1289-1406 N; p < 0.01). No difference in the collagen type I concentration was detected (N.S.). CONCLUSION: Porcine flexor and bovine extensor tendons are eligible substitutes with similar stiffness and high failure loads compared with human cadaveric semitendinosus tendons in in vitro studies.

ABSTRACT

OBJECTIVE: Stabile recentering the extensor tendon over the top of the head of the metacarpal to restore the exact tension and the direction. INDICATIONS: Dislocation of the extensor tendon at the metacarpophalangeal (MP) joint with functional disabilities of the fingers. CONTRAINDICATIONS: Severe osteoarthritis of the MP joint. Accompanying injuries of collateral ligaments. Fibrosis of the MP joint or contractures of the intrinsic muscles. SURGICAL TECHNIQUE: Curved 8 cm skin incision at distal metacarpal, MP joint, and proximal phalanx. A distally pedicled central tendon strip from the extensor digitorum communis (EDC) tendon is removed. Centralization of the tendon by reconstructing the sagittal ligament and the proximal part of the extensor hood. The tendon strip is wrapped around the tendon of the interossous muscle. POSTOPERATIVE MANAGEMENT: Immobilization of the MP joint in 30° flexion with free proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints for 4 weeks. Full fist after 5 weeks. RESULTS: In all 16 patients good or very good results were achieved. There were no recurrences of tendon dislocations, no MP joint contractures, and only a few minor extensor tendon adhesions.

ABSTRACT

BACKGROUND: The success of the flexor tendon suture depends on many factors. An important factor is that the tendon suture technique that must be carried out for flexor tendons is considerably more complex and more precise than for all other tendons of the body. OBJECTIVES: To discover important technical points that need to be considered during flexor tendon suturing. METHOD: We compiled the most important technical details in flexor tendon suturing from the literature and from personal experience. RESULTS: Details on core suture, peripheral suture, the tensile strength, gapping, the circulation of sutured tendons, gliding resistance and excisions are discussed. CONCLUSIONS: Flexor tendon suturing must be performed taking great care to conserve tissue.

ABSTRACT

BACKGROUND: To ensure proper function of the flexor tendons, pulleys are extremely important. Pulleys can be impaired by injury, infection, but also sometimes iatrogenically. The consequences of this failure are often poorly understood. OBJECTIVES: What is the impact of pulley insufficiency, what are the clinical signs, and what are the reconstruction options? METHODS: The experiences of 64 patients with different forms of pulley insufficiency are presented. RESULTS: All patients benefit from a ring ligament reconstruction. A phalanx fracture can be one complication. CONCLUSIONS: Pulley reconstructions are very beneficial operations.

ABSTRACT

BACKGROUND: Insufficiency of both flexor tendons of a finger considerably disrupts the function of the whole hand. Flexor tendon transplantation represents the best way to reconstruct or improv function in many cases. OBJECTIVES: Based on the literature and our own results, not only the current state of the surgical technique, but also the opportunities and dangers of this sophisticated operation, are represented. Knowledge of alternative methods is important. METHODS: With a follow-up of between 2 to 12 years, a total of 272 patients who underwent flexor tendon transplantation in the hand during several periods from 1974 to 2000 were investigated. RESULTS: Similar to the international literature, our long-term results did not specify the exact surgical technique (pedicled or free). According to the Buck-Gramcko score, 32 % had very good results, 26.4 % good, 15.1 % satisfactory, and 26.5 % poor. CONCLUSIONS: Numerous details need to be considered before, during, and after surgery. For the patient, the procedure has tremendous significance in many ways; thus, this operation should only be performed by an experienced hand surgeon.

ABSTRACT

OBJECTIVE: Restoring stability and preventing subluxation/dislocation of the trapeziometacarpal (first carpometacarpal = CMC-I) joint while preserving mobility. INDICATIONS: Posttraumatic, acquired or congenital instability of the CMC-I joint. CONTRAINDICATIONS: Existence of osteoarthritis of the CMC-I joint. Neurogenic or muscular origin dysfunction of thenar muscles and other contractures the CMC-I area. Infections. SURGICAL TECHNIQUE: Radiopalmar approach to the CMC-I joint, reduction, and transosseous ligament reconstruction with a distally pedicled tendon strip from the abductor pollicis longus muscle. POSTOPERATIVE MANAGEMENT: Splint immobilization for 5 weeks. RESULTS: This procedure generally results in good or very good outcomes. Of 24 patients, only one patient experienced rupture of the ligament reconstruction. Ligament reconstruction for the carpometacarpal joint of the thumb relieves pain and restores stability while preserving functional range of motion in patients with chronic instability.

ABSTRACT

OBJECTIVE: Restoration of ulnar collateral ligament stability of the metacarpophalangeal (MP) joint of the thumb with elimination of palmar subluxation while retaining mobility for chronic instability without osteoarthritis. INDICATIONS: Acquired or congenital chronic instability of the MP joint of the thumb with compelling reasons for joint preservation and against arthrodesis, e.g., an arthrodesis or arthritis of adjacent joints. CONTRAINDICATIONS: Arthritis of the thumb MP joint. Contractures of the MP joint. Low natural range of motion of the joint (compared to the contralateral hand). Additional palmar instability with significant hyperextensibility. Infections. Lesions to the median and/or ulnar nerve with impaired active mobility. SURGICAL TECHNIQUE: Anatomical reconstruction of the ulnar collateral ligament and the accessory collateral ligament using a tendon graft (palmaris longus tendon). Ulnar approach, transosseous course of the tendon graft and elimination of subluxation. POSTOPERATIVE MANAGEMENT: Splint for 5 weeks and hand therapy. RESULTS: Of 12 patients undergoing this type of ligament reconstruction, all achieved good stability and pain-free range of motion, which was 60-95% of the contralateral hand. This surgical procedure has few complications and is considered reliable.

ABSTRACT

INTRODUCTION: Bicycles are becoming increasingly popular. In Münster, a German town with a population of 273,000, bicycles were the main method of transportation in 2009, used more often (37.8%) than cars (36.4%). Each day in Münster, bicycles are used around 450,000 times. In 1982, they were only used around 270,000 times a day. However, the increased use of bicycles has also led to an increased number of bicycle accidents. METHODS: Between February 2009 and January 2010, data on bicycle-accidents leading to injuries were collected by the Police of Münster and in all emergency units of the six hospitals in Münster. A systematic acquisition of technical data from the police and the medical data from the hospitals were combined anonymously. None of the forms contained personal data of patients involved, except for patient age and sex as well as time and place of bicycle accidents to match the questionnaires. The data were entered into a central database (MS Access for input/MySQL for data retrieval). RESULTS: 2250 patients were included in this study. For each of these patients either a patient record or a hospital record or a police record or a combination of any of these different records existed in our database. In total, 1767 patients received medical treatment at a hospital and 484 people included in the study did not go to a hospital. Three fatalities occurred as a result of bicycle accidents. Considering reasons for hospital admission, traumatic brain injuries were the leading cause (25.7%). However, the largest resource consumption was attributed to fractures of the upper extremities (36.8%) and lower extremities (29.9%) with major surgery. DISCUSSION: Bicycle accidents occur more frequently than indicated by police records. The results of the Münster Bicycle Study have shown that the actual number of bicycle accidents exceeds the officially reported number by nearly two times. Since bicycle helmets cannot prevent accidents it is recommended not only to focus on helmet use as the only injury prevention method. Other factors, such as weather, pavement and default of traffic, roadworthiness of the bicycles or alcohol/drug abuse also affect the accident rates.

ABSTRACT

Due to medical improvements surgeons are increasingly confronted with conditions associated with severe medical comorbidities. Fracture or nonunion of the femoral neck would have been classified as "inoperable" in the past. We report the successful operative treatment of a patient with femoral neck nonunion after screw osteosynthesis and associated existence of a left ventricular assist device for dilated cardiomyopathy.

ABSTRACT

An osteochondral transfer of a scaphoid segment into the lunate fossa in proximal row carpectomy was performed in two female patients in stage IV of Kienböck's disease. Clinical and radiological follow-up at 18 and 6 months, respectively, showed results comparable to those of PRC in Lichtman stage III. This technique may serve as another option for salvage operations on the wrist.
